accident prevention measures.  
Indicates an imminently hazardous situation which, if not avoided,  
WILL result in death or serious injury.  
Indicates a potentially hazardous situation which, if not avoided,  
COULD result in death or serious injury.  
Indicates a potentially hazardous situation which, if not avoided,  
MAY result in minor or moderate injury. It may also be used to alert

Additional Safety for Drum Sanders  
1. FEEDING STOCK. DO NOT allow anyone  
to stand at the outfeed end when feeding  
your stock. Never sand more than one  
piece of stock at a time.  
6. DUST COLLECTION SYSTEM. Never  
operate the sander without an adequate  
dust collection system in place and run-  
ning.  
DO NOT jam the workpiece into the  
machine during operation. Firmly grasp the  
workpiece in both hands and ease it into  
the machine using light pressure.  
7. BE ATTENTIVE. Never leave the machine  
running unattended.  
8. REPLACING SANDING PAPER. Replace  
sanding paper when it becomes worn or  
damaged.  
2. MINIMUM STOCK DIMENSIONS. DO NOT  
1
sand any stock thinner than 16", narrower  
than 18", or shorter than 9". DO NOT sand  
thin stock by using a “dummy” board under  
your workpiece.  
9. EXPERIENCING DIFFICULTIES. Any  
problem, with the exception of convey-  
or belt tracking that is concerned with  
any moving parts or accessories, must be  
investigated and corrected with the power  
disconnected, and after all moving parts  
have come to a complete stop.  
3. CLOTHING. DO NOT wear loose clothing  
while operating this machine. Roll up or  
button sleeves at the cuff.  
4. HAND PROTECTION. DO NOT place  
hands near, or in contact with, sanding  
drums during operation. DO NOT allow  
fingers to get pinched between board and  
conveyor belt during operation. This may  
pull the operator’s hand into the machine  
and cause serious injury or death!  
10. MAINTENANCE AND ADJUSTMENTS.  
Never attempt to adjust conveyor belt track-  
ing when the sanding drums are running.  
Perform machine inspections and main-  
tenance service promptly when called for.  
Disconnect power before performing main-  
tenance or adjustments on the sander.  
5. INSPECTING WORKPIECES. Always  
inspect one workpiece at a time for nails,  
staples, knots, and other imperfections that  
could be dislodged and thrown from the  
machine during sanding operations.  
11. RESPIRATOR AND SAFETY GLASSES.  
Always wear a respirator and safety glass-  
es while operating the machine. Dust and  
chips are created when sanding. Some  
debris will be ejected, becoming hazards to  
the eyes and lungs.  
No list of safety guidelines can be complete.  
Every shop environment is different. Always  
consider safety first, as it applies to your  
individual working conditions. Use this and  
other machinery with caution and respect.  
Failure to do so could result in serious per-  
sonal injury, damage to equipment, or poor  
work results.  
Like all machines there is danger associat-  
ed with the Model G0449/G0450. Accidents  
are frequently caused by lack of familiarity  
or failure to pay attention. Use this machine  
with respect and caution to lessen the pos-  
sibility of operator injury. If normal safety  
precautions are overlooked or ignored, seri-  
ous personal injury may occur.

G0450 at 440V  
Power Connection  
Because of the high amperage draw from this  
machine, we recommend that you hardwire it  
directly to your circuit breaker and install a locking  
shut-off lever (see Figure 3) near the machine as  
a way to quickly disconnect the power and pre-  
vent accidental starting.  
Serious personal injury could occur if you  
connect your machine to the power source  
before you have completed the set up pro-  
cess. DO NOT connect the machine to the  
power source until instructed to do so.  
220V Pre-Wired

Phase Converter  
with G0450  
When using a phase converter, the power from  
the manufactured power leg (sometimes called  
the wild wire) can fluctuate. Connect the manu-  
factured power leg to the L2 terminal to prevent  
damage to the transformer. The wire from the L2  
terminal can handle some fluctuation because it  
goes directly to the motor. The power going to the  
L1 and L3 terminals goes to the controls and must  
be consistent to prevent damage.  
Minimum Circuit Requirement 440V........30 Amp  
Minimum Cord Requirements  
A cord is not provided with your machine. For  
440V 3-phase operation, use the following type

Grounding  
Rewiring to 440V  
In the event of an electrical short, grounding  
reduces the risk of electric shock. The grounding  
wire in the power cord must be properly connect-  
ed to the grounding prong on the plug; likewise,  
the outlet must be properly installed and ground-  
ed. All electrical connections must be made in  
accordance with local codes and ordinances.  
The Model G0450 can be rewired for 440V  
operation. This rewiring job consists of replacing  
the existing control panel box with a 440V control  
panel box and rewiring the motor.  
The 440V conversion kit can be purchased as  
#P0450253 by calling (800) 523-4777.  
Improper connections of the electrical-grounding  
conductor increases the risk of electric shock.  
Check with a qualified electrician or one of our  
service personnel if you do not understand  
the grounding instructions, or if you doubt the  
machine is properly grounded.  
This procedure takes moderate electrical skill and  
the rewiring job must be inspected by a qualified  
electrician before connecting to power.  
To rewire the Model G0450 for 440V opera-  
tion:  
1. Disconnect the saw from the power  
source!  
Electrocution or fire could  
result if this machine is  
not grounded correctly  
or if your electrical con-  
figuration does not com-  
ply with local and state  
codes. Ensure compliance  
by checking with a quali-  
fied electrician!  
2. Rewire both motors according to the dia-  
grams on the inside of the junction box  
cover.  
Note: These drawings are also shown in  
Figure 55 for your reference, but always use  
the drawings in the junction box cover, as  
they will reflect any changes to the machine  
since the time of writing.  
3. Open the electrical panel and familiarize  
yourself with Figures 54 & 56 for component  
locations.  
Extension Cords  
4. Keeping track of the wire locations, discon-  
nect all power and motor wires, so the con-  
trol panel box can be completely removed.  
Because of the high amperage draw from this  
machine, we do not recommend the use of exten-  
sion cords. Instead, position your equipment near  
installed wiring to eliminate the need for exten-  
sion cords.  
5. Remove and replace the control panel box  
with the box from the 440V conversion kit.  
6. Connect the power and motor wires to the  
new control panel box in the same manner  
that they were removed from the old box.  
7. Have the wiring job inspected by a qualified  
electrician.

Placing Sander  
Mounting to Floor  
Although not required, we recommend that you  
mount your new machine to the floor. Because  
this is an optional step and floor materials may  
vary, floor mounting hardware is not included.  
The Model G0449/G0450  
has a shipping weight of  
1190/1275 lbs. Serious

ods are not followed. To  
be safe, get assistance  
and use power equip-  
ment when moving the  
crate and removing the  
machine from the crate.  
Bolting to Wood Floors  
The most secure method of mounting this drum  
sander to a wood floor is using 38" hex bolts with  
flat washers, and securing the bolts from under  
the floor with flat washers, lock washers and hex  
nuts. Use lag bolts with washers only if you do not  
have access to the underside of the floor.  
Bolting to Concrete Floors  
3
Lag shield anchors with 8" lag bolts or anchor  
studs (Figure 10) are two popular methods for  
anchoring an object to a concrete floor. We sug-  
gest you research the many options and methods  
for mounting your machine and choose the best  
that fits your specific application.  
Use lifting straps with a combined minimum  
of 1500 lbs. lifting capacity. If lifting straps  
break, serious personal injury may occur.  
To place the sander in a permanent location:  
1. Unbolt the sander from the pallet.  
2. Position the forklift forks directly above the  
sander. Place two lifting straps with hooks on  
the ends over the forklift forks and slide the  
hooks into the points shown in Figure 9.  
Figure 10. Concrete anchor options.  
NOTICE  
Concrete anchor studs are stronger and  
more permanent alternatives to lag shield  
anchors; however, they will stick out of the  
floor, causing a tripping hazard if you decide  
to move your machine at a later point.  
Figure 9. Lifting the sander.  
3. Lift the sander and move it to your predeter-  
mined location. DO NOT lift it any higher than  
is necessary to clear the floor.

panel and lift off the face plate.  
Gear Oil Check  
It is important to make sure the gear box has oil in  
it before running the sander for the first time. This  
is to ensure the gears do not burn up.  
To check the gear oil:  
1. Remove the feed motor cover, and check the  
sight glass shown in Figure 15 to make sure  
gear oil is present.  
Figure 13. G0449 control panel wiring.  
2. Feed the power cord through the strain relief  
on the bottom of the control panel, tighten  
the strain relief, connect the cord to the ter-  
minals shown in Figure 13 or 14, and close  
the control panel.  
Note For Model G0450 Only: When using a  
phase converter, connect the manufactured  
power leg to the L2 terminal (Figure 14).  
The L2 terminal can handle power fluctuation  
because it is wired directly to the motor. The  
other wires connect to the controls and must  
be consistent to prevent damage.

Adjustments  
Now that the machine is connected to the power  
source, it is important to perform a test run to  
make sure all the controls are working properly.  
For your convenience, the adjustments listed  
below have been performed at the factory and  
no further setup is required to operate your  
machine.  
Before starting the sander, make sure you  
have performed the preceding assembly  
and adjustment instructions, and you have  
read through the rest of the manual and  
are familiar with the various functions and  
safety issues associated with this machine.  
Failure to follow this warning could result in  
serious personal injury or even death!  
However, because of the many variables involved  
with shipping, some of these adjustments may  
need to be repeated to ensure optimum results.  
Keep this in mind as you start to use your new  
drum sander.  
Step-by-step instructions for these adjust-  
ments can be found in SECTION 7: SERVICE  
ADJUSTMENTS.  
To test run the sander:  
1. V-Belt Service (Page 30). Perform after the  
first 16 hours.  
1. Put on safety glasses and make sure any  
bystanders are out of the way and also wear-  
ing safety glasses.  
2. Conveyor Tensioning & Tracking (Page 32).  
3. Drum Adjustments (Page 33).

SECTION 4: OPERATIONS  
Operation Safety  
Depth of Cut  
The optimum depth of cut will vary based on  
the type of wood, feed rate, and sandpaper grit.  
Under most sanding conditions, the depth should  
not exceed 64" or 0.4mm (approx. 4 turn of the  
handwheel). Each full turn of the table height  
handwheel raises the conveyor table approxi-  
mately 0.020" (0.5mm). Attempts to remove too  
much material can cause jamming, wood burning,  
rapid paper wear or tearing, poor finish and belt  
slippage.  
Damage to your eyes, lungs, and ears could  
result from using this machine without  
proper protective gear. Always wear safety  
glasses, a respirator, and hearing protection  
when operating this machine.  
1
3
To set the depth of cut:  
1. Rotate the table height handle (Figure 16)  
until the table is too low, then raise the table,  
allowing a gap between the workpiece and  
the sanding drum.  
Loose hair and cloth-  
ing could get caught in  
machinery and cause seri-  
ous personal injury. Keep  
loose clothing and long  
hair away from moving  
machinery.  
Note: When adjusting the table to sand a  
thicker workpiece, lower and then raise the  
table to remove backlash from the adjust-  
ment mechanism.  
NOTICE  
If you have never used this type of machine  
or equipment before, WE STRONGLY REC-  
OMMEND that you read books, trade maga-  
zines, or get formal training before begin-  
ning any projects. Regardless of the con-  
tent in this section, Grizzly Industrial will  
not be held liable for accidents caused by  
lack of training.  
Figure 16. Table height handwheel.  
2. Start the conveyor and sanding drums and  
feed the workpiece into the sander. SLOWLY  
raise the conveyor table until the workpiece  
makes light contact with the sanding drums.  
This is the correct height to begin sanding the  
workpiece.

Variable Speed  
Sanding  
The variable speed knob allows you to increase  
the feed rate from 6–18 FPM. The correct speed  
to use depends on the type of stock you are using  
(hardwood vs. softwood) and the stage of finish  
you are at with that workpiece.  
DO NOT sand more than one board at a time.  
Minor variations in thickness can cause one  
board to be propelled by the rapidly spinning  
sanding drum and ejected from the machine.  
NEVER stand directly in front of the outfeed  
area of the machine. Failure to do so could  
result in severe personal injury.  
As a general rule, a slower feed rate will sand  
the surface smoother, but runs the risk of burning  
the wood; a faster feed rate will remove material  
faster, but runs the risk of overloading the motor.  
Use trial-and-error to determine the best settings  
for your specific applications.  
The digital readout displays the combined amper-  
age draw of the motors. The number on the digital  
readout increases when a load is placed on the  
machine. Use this meter to avoid pushing your  
machine to its maximum load; instead of maxing  
out your machine, make multiple passes or install  
a coarser grit paper. Since various types of wood  
will cause different loads, use trial-and-error to  
determine the best settings for your application.  
To adjust the conveyor speed:  
1. Start the conveyor (DO NOT adjust conveyor  
speed when the conveyor motor is OFF).  
NOTICE  
Adjusting the variable speed when the con-  
veyor motor is OFF can damage the V-belt  
and the adjusting mechanism.  
G0449 Maximum Amp Load .......................47A  
G0450 Maximum Amp Load at 220V .........39A  
G0450 Maximum Amp Load at 440V .........20A  
2. Rotate the variable speed knob (Figure 17)  
counterclockwise to increase the feed speed,  
or clockwise to decrease the feed speed.  
To sand a workpiece:  
1. Adjust the table height according to the  
instructions in Depth of Cut on Page 21.  
2. Start the dust collector, the drum motor, and  
the feed motor.  
3. Feed the workpiece through the sander and  
monitor the amp meter; if it approaches the  
maximum amp load, lower the conveyor  
table. Retrieve the workpiece by standing at  
the side—not at the outfeed end.  
4. Run wide stock through two or three times  
without adjusting the table height. Turn the  
stock 180° between passes to ensure an  
even cut.

Sanding Tips  
Choosing Sandpaper  
Replace the sandpaper with a higher grit to  
achieve a finer finish.  
There are many types of sanding belts to choose  
from. We recommend Aluminum Oxide for gen-  
eral workshop environments. Below is a chart  
that groups abrasives into different classes, and  
shows which grits fall into each class.

Raise the table with a maximum of 4 turn of  
the height handle until the workpiece is the  
desired thickness.  
Grit  
Class  
Usage  
Reduce snipe when sanding more than one  
board of the same thickness by feeding them  
into the sander with the front end of the sec-  
ond board touching the back end of the first  
board.

planer  
Finish sanding.  
DO NOT sand boards less than 9" long  
1
or less than 16" to prevent damage to the  
workpiece and the drum sander.  
The general rule of thumb is to sand a workpiece  
with progressively higher grit numbers, with no  
one grit increase of more than 50. Avoid skipping  
grits; the larger the grit increase, the harder it will  
be to remove the scratches from the previous  
grit.  
Extend the life of the sandpaper by regularly  
using a PRO-STICK® sanding pad (Page  
25).  
When sanding workpieces with irregular sur-  
faces, such as cabinet doors, take very light  
sanding passes to prevent gouges. When  
the drum moves from sanding a wide surface  
to sanding a narrow surface, the load on  
the motor will be reduced, and the drum will  
speed up, causing a gouge.  
The Model G0449/G0450 allows you to place a  
different grit sandpaper on each drum. The first  
drum should have a coarser grit than the sec-  
ond. Usually this translates into combinations  
of successive group types. A common selection  
for stock that is planed before being sanded is a  
100/150 grit combination.  
DO NOT edge sand boards. This can cause  
boards to kickback, causing serious personal  
injury. Edge sanding boards also can cause  
damage to the conveyor belt and sandpa-  
per.  
Ultimately, the type of wood you use and your  
stage of finish will determine the best grit types to  
install on your sander.  
When sanding workpieces with a bow or  
crown, place the high point up (prevents the  
workpiece from rocking) and take very light  
passes.  
Feed the workpiece at an angle to maximize  
stock removal and sandpaper effectiveness,  
but feed the workpiece straight to reduce  
sandpaper grit scratches for the finish pass-  
es.

tension tool into the head of the cap screw  
securing the spring (see the inset box in  
Figure 18), then place the spring tension tool  
over the arm of the tension wheel as shown  
in Figure 18.  
8. Tightly spiral the paper onto the drum, ensur-  
ing there are no bubbles or overlapping  
3
edges. Try to leave a uniform 16" gap  
between the spirals as you wind the paper  
around the drum. This will allow the paper to  
move and stretch slightly and will decrease  
the likelihood of overlapping and tearing.  
4. Remove the screwdriver, then lightly tighten  
the Phillips head screw in the spring tension  
tool to secure it to the tension wheel.  
9. Fold the corner of the loose end into the  
spring clip, then install the clip onto the ten-

any features of the machine while it is run-  
ning. Wait until the machine is turned OFF,  
unplugged, and all working parts have come  
to a rest before you do anything!

Gearbox: The oil in the gearbox should be  
changed every 500 hours with new SAE 80W  
gear oil.  
Cleaning  
1. Remove the motor cover, loosen the four hex  
bolts that secure the gear box to the motor  
bracket, and remove the V-belt.  
Cleaning the Model G0449/G0450 is relatively  
easy. From time to time vacuum wood dust off of  
the internal components, especially the motor.

Failure to routinely inspect your drum sander  
for damage and wear could result in unsatis-  
factory work results, premature component  
or machinery failure, or operator injury. We  
recommend you create a checklist for routine  
inspection and maintenance. Remember to  
always disconnect the drum sander from its  
power source before attempting to inspect,  
adjust, or repair this machine!  
Table Lift Screws: These should be lubricated  
with lithium grease every six months.  
Clean the table lift screws (Figure 25) and rub  
lithium grease onto the threads. Move the table  
up or down to spread the grease thoroughly over  
the threads.

The gauge blocks described here will be required  
to complete most of the service procedures in this  
section. After you have made them, they can be  
conveniently stored inside of the sander cabinet  
for future use.  
Tension  
New V-belts often stretch and loosen up during  
the first 16 hours of use. After this period, they  
should be inspected and re-tensioned if neces-  
sary.  
To make the gauge blocks:  
Proper tension is important for optimum power  
transmission. However, too much tension may  
cause premature bearing failure.  
1. Edge joint the concave edge of the 2x4 flat  
on a jointer, as shown in Figure 27.  
The correct V-belt tension is achieved when the  
1
V-belts can be deflected 2"–34" when pushed in  
the middle with moderate pressure. See Figure  
29 for an example of how to perform a V-belt  
deflection test with a straightedge and ruler.  
Figure 27. Edge jointing on a jointer.  
2. Place the jointed edge of the 2x4 against the  
table saw fence and rip cut just enough off  
the opposite side to square up the two edges  
of the 2x4, as shown in Figure 28.

3. Cut the 2x4 into two even pieces to make two  
36" long wood gauge blocks.  
Note: The Steps 1 & 2 can be skipped, but  
having these wood gauge blocks at an even  
height is critical to the accuracy of your over-  
all adjustments.

To adjust V-belt tension:  
Pulley Alignment  
Pulley alignment is another important factor in  
power transmission and belt life. The pulleys  
should be parallel to each other and in the same  
plane (coplaner) for optimum performance.  
1. Disconnect power to the sander!  
2. Open the side cover.  
3. Turn the motor mount nuts in the direction  
shown in Figure 30 to loosen or tighten the  
V-belts.  
Each pulley can be adjusted by loosening the set  
screw that secures the pulley to the shaft, sliding  
the pulley in/out, and retightening the set screw to  
lock the pulley in place.  
To align the pulleys:  
1. Disconnect power to the sander!  
2. Open the pulley cover.  
3. Remove the V-belts.  
Loosen  
V-Belts  
Tighten  
V-Belts  
4. Place a straightedge across the face of the  
motor pulley and front drum pulley to check  
the alignment. The straightedge should sit  
evenly on the top and bottom part of both pul-  
leys, as shown in Figure 31.  
Figure 30. V-belt tension controls.  
5. Repeat Step 4 with the straightedge placed  
against the motor pulley and rear drum pul-  
ley.  
Removal/Replacement  
Replace the V-belt if you notice fraying, cracking,  
glazing, or any other damage. A worn/damaged  
V-belt will not provide optimum power transmis-  
sion from the motor to the drums.  
6. Adjust the pulleys as necessary until they are  
all coplanar with each other.  
V-belt removal and replacement is simply a matter  
of loosening the V-belts until you can roll them off  
the pulleys, replacing them with a MATCHED set,  
then re-tensioning them.  
Note: A matched set means all the V-belts are  
the same size and also have the same serial  
number.

3. Turn both of the conveyor adjustment bolts  
clockwise one full turn at a time until the con-  
veyor belt no longer slips during operation.  
Conveyor Tensioning  
& Tracking  
—If the conveyor starts tracking to one side,  
immediately turn the drum sander OFF and  
perform the tracking instructions.  
Tools Needed:  
Qty  
Wrench 19mm................................................... 1  
4. Tighten the lock nuts to lock the conveyor  
adjustment bolts in place.  
Tensioning  
The conveyor may slightly stretch with continued  
use and will eventually need to be tensioned. This  
is most obvious if the conveyor starts slipping on  
the rollers.  
Tracking  
The conveyor must track straight. If the conveyor  
tracks to either side, then the tracking must be  
corrected or the conveyor will become damaged  
and have to be replaced.  
When you tension the conveyor, focus on ten-  
sioning the adjustment bolts in even increments.  
Tensioning one side more than the other will  
cause tracking problems, which will require you to  
take additional steps to get the sander operating  
correctly.  
Replacing a damaged conveyor is a big job.  
Always be careful to make sure that the belt does  
not travel too far to one side or the other.  
Tracking the conveyor is a balancing process that  
takes patience and a small degree of trial-and-  
error. Usually you must over-tighten the loose side  
(the side the belt is tracking towards) to make the  
conveyor move to the middle of the rollers, then  
loosen that same side to make the conveyor stay  
in position. If you adjust the bolt too much either  
way, then you have to repeat the process until the  
conveyor rides in the middle and stays there dur-  
ing continuous operation.  
To tension the conveyor:  
1. Loosen the lock nut, shown in Figure 32, on  
both sides of the conveyor.  
Adjustment  
Bolt  
To track the conveyor:  
1. Turn the conveyor ON and watch it track.  
2. Determine which side the conveyor is track-  
ing towards (the loose side) and tension the  
adjustment bolt on that side until the con-  
veyor tracks in the opposite direction.  
Lock Nut  
Figure 32. One side of conveyor tensioning &  
tracking controls (guard removed for clarity).  
Note: Tracking changes may take up to three  
minutes before they are noticeable.  
2. Use a magic marker, white out, or fingernail  
polish to mark the front of the conveyor ten-  
sioning bolt on both sides. This step will aid  
you in keeping track of the rotations as you  
turn the bolts, so they remain as even as pos-  
sible.  
3. When the conveyor is near the middle of the  
rollers or table, loosen the adjustment bolt  
until the conveyor stops moving and tracks  
straight.  
—If the conveyor tracks too far to the other  
side, then adjust the bolt as necessary to  
bring it back and repeat Steps 2 & 3 until  
the tracking is correct.

The drums can be adjusted in fine increments at  
the pillow bearings and in larger increments by  
using the table lift screws (Page 27).  
Drum Adjustments  
Tools Needed:  
Qty  
While adjusting the drums, keep in mind that  
having the drums parallel to the conveyor belt is  
critical to the sanding operation. Care should be  
taken to make the tolerances as close as possible  
(within 0.002" from one side to the other) when  
adjusting the drum heights.

even allowing up to 8" difference from one side  
When adjusting the drums, they must be aligned  
in two ways—perpendicular to the feed direction  
(Figure 33) and parallel to the conveyor belt  
(Figure 34). In addition, the rear drum should be  
set approximately 0.020" (0.5 mm) below the front  
drum. (This amount is equal to one full crank of  
the handwheel.)  
to the other before causing problems.  
To align the drums:  
1. Disconnect power to the sander!  
2. Open the top and V-belt covers and remove  
the V-belts (see Page 31).  
3. Remove the sandpaper from the drums.  
 
4. Loosen the lock nuts (see Figure 35) on the  
front drum pillow bearing.

5. Place the gauge blocks on the conveyor table  
and position them under the drum rollers, as  
shown in Figure 36.  
10. Adjust the height of the drum ends by loosen-  
ing the locknuts and sliding the pillow bearing  
up or down along the wedge.  
—If you need more room behind the drum,  
adjust the dust scoop as described in Dust  
Scoop Position on Page 37.  
—If you need to move the drum up or down  
more than can be done at the pillow bear-  
ing, then you need to adjust the table lift  
screw in that corner. Refer to Table Lift  
Screws on Page 27.  
11. At both ends, measure the distance between  
the edge of the rear drum and the rear upper  
frame angle, as shown in Figure 37. The dif-  
ference between these two measurements  
will tell you how close the drum is to being  
perpendicular to the feed direction.  
Figure 36. Gauge blocks positioned under the  
ends of the drums.  
6. Raise the table until the gauge blocks just  
touch the rear drum.  
Note: A good way to know when they are  
touching is to rock the rear drum back and  
forth while raising the table until you hear or  
feel contact with the gauge blocks.

8. Starting at one end, find the largest size  
feeler gauge that can pass between the  
rear drum and your gauge block. (The feeler  
gauge should slide with moderate resistance,  
without forcing the drum to roll.)

15. Raise the table up until the gauge blocks just  
touch the rear drum, as described in Step 7.  
16. Adjust the height of the front drum ends by  
loosening the locknuts and sliding the pillow  
bearing up or down along the wedge until the  
largest size feeler gauge you can fit between  
the front drum and gauge blocks at both ends  
is 0.015". This will reflect the rear drum depth  
of cut.  
19. Tighten all the lock nuts.  
20. Check the height of the drum ends to make  
sure they did not move.  
—If they did not move, you have successfully  
adjusted the drums. Congratulations!  
Note: The 0.015" setting is based off the  
suggested depth of cut in the SECTION  
4: OPERATIONS; however, you can set  
the front drum between 0.005" and 0.025",  
depending on the sandpaper grit size you will  
use (ie, coarse grit = larger number; fine grit  
= smaller number).  
—If they did move, repeat Steps 17-18.  
21. Calibrate the scale pointer as described on  
Page 37.  
17. At both ends, measure the distance between  
the edge of the front drum and the front upper

Note: An additional trick for eliminating snipe is  
to reduce pressure on the rear rollers, but not the  
front rollers. Conditions will vary with wood types,  
so use trial-and-error to find the best results for  
your application.

To adjust the pressure rollers to the factory  
setting:  
Factory Setting:  
Distance Below Rear Drum........... 0.160" (4mm)  
1. Disconnect power to the sander!  
The pressure rollers are factory set at 0.160"  
(4mm) below the bottom of the rear sanding drum  
and are fully adjustable either up/down with the  
two nuts shown in Figure 39. After the adjust-  
ment has been made, always lock the top hex nut  
against the bottom to prevent it from moving.  
2. Open the top cover.  
3. Place the gauge blocks on the conveyor table  
and position them under all the pressure roll-  
ers, as shown in Figure 40.  
Figure 40. Gauge blocks in position for  
adjusting the pressure roller height.  
Figure 39. Pressure roller adjustment hex nuts.  
Proper pressure on the workpiece helps avoid  
kickback and keeps the workpiece from slip-  
ping. However, as pressure increases on the  
workpiece, snipe also increases (snipe is normal  
with all brands of drum sanders).  
4. Adjust the conveyor table up so the gauge  
blocks just touch the rear drum roller.  
5. Rotate the handwheel eight full turns, count-  
ing from the point of actual table movement  
so handwheel freeplay does not affect your  
count.  
If snipe becomes a problem, you can minimize  
it by reducing pressure (raising pressure roller  
height). However, you can only minimize it so  
much before the workpiece will slip or kick out,  
causing a hazard to the operator. If this happens,  
you have raised the pressure rollers too high for  
them to function as intended—the pressure rollers  
MUST be lowered to prevent injury.  
6. With all the rollers: 1) Raise one end off the  
gauge block and move it back down until it  
just touches the gauge block; 2) repeat with  
the other side; 3) tighten the hex nuts togeth-  
er to make sure the adjustments are locked  
in place.

In order for the scale pointer to be accurate, it  
must be calibrated.  
The dust scoop helps control the effectiveness  
of the dust collection system, thus reducing  
the amount of dust that accumulates on the  
workpiece as it travels through the sander.  
We recommend calibrating your scale pointer  
any time you adjust the drum heights or table lift  
screws.  
To adjust the dust scoop position:  
1. Disconnect power to the sander!  
2. Open the top cover.  
To calibrate the scale pointer:  
1. Sand a workpiece with the drum sander  
and measure the thickness of the sanded  
workpiece.  
3. Loosen the four button head cap screws,  
shown in Figure 41, that secure the dust  
scoop to the rear upper angle.  
2. Loosen the screw that secures the scale  
pointer and adjust it to the thickness of the  
workpiece.  
4. At both ends, adjust the dust scoop forward/  
backward until there is a 4mm gap between  
the rear drum and the dust scoop at the nar-  
rowest point (use the 4mm hex wrench as a  
gauge; Figure 41), and tighten the four but-  
ton head cap screws.

or if you have removed the table or chain during  
a service procedure and you need to reset the  
drums parallel to the table.  
Each tooth on the sprocket represents 0.006" or  
.16mm of table elevation movement. For example,  
if the rear of the table was 0.006" low, rotate both  
rear table lift screws to the next sprocket tooth in  
the same chain position. You can easily rotate the  
sprockets from the top of the table lift screws with  
a flat head screwdriver.  
To adjust the table lift screws:  
1. Disconnect power to the sander!  
2. Open the side cover.

6. Carefully move the chain off of only the  
marked sprocket.  
3. Raise the table up to at least the 1" mark on

difference in height needed.  
the height scale.  
4. At the lift screw that needs to be adjusted,  
mark the end of a sprocket tooth and the  
chain hole where that tooth is meshed, as  
shown in Figure 42.  
8. Fit the chain back over the sprocket, making  
sure the new sprocket tooth is inserted into  
the marked chain hole.  
9. Re-tension the chain and check the new

height setting.  
Marking the chain and sprocket locations  
will save you a substantial amount of time  
when you reinstall the chain. Make sure you  
have done this before removing the chain.  
10. Repeat Steps 5–9 as needed until the table  
height is parallel to the drums in all four cor-  
ners, and calibrate the scale pointer.

5. Remove the sanding drums (4 hex nuts and  
4 flat washers on each one).  
Replacing the conveyor belt is a big job and  
requires moderate mechanical skill and a fair  
amount of patience. For planning purposes,  
expect to have your machine out of operation for  
at least a few hours.  
6. Place the gauge blocks face down, as shown  
in Figure 45, raise the table to relieve the  
spring pressure on the pressure rollers,  
remove the pressure roller nuts, and lower  
the table to remove the pressure rollers.  
As you remove hardware to complete these  
instructions, we recommend putting all the bolts,  
screws, washers, etc. back into the holes from  
which they came. This simple habit will take  
slightly longer when disassembling the machine,  
but it will save you a lot of time and reduce frus-  
tration during reassembly.  
To replace the conveyor belt:  
1. Disconnect power to the sander!  
2. Remove the top cover (6 button head screws)  
and pulley cover (4 hex bolts).  
3. Remove the rear dust scoop (4 button head

7. Remove the front and rear upper frame  
angles (4 cap screws, 4 lock washers, and 4  
flat washers on each one).  
12. Raise the table up to the 1" mark on the  
scale.  
13. Mark the chain and sprockets.  
8. Remove the table elevation lock knob.  
14. Loosen the chain idler adjustment sprocket,  
carefully pull the chain off of all the sprockets,  
and remove it from the cabinet by undoing  
the chain master link, as shown in Figure  
47.  
9. Remove the feed motor cover (4 button head  
screws and setscrew on knob).  
10. Remove the front conveyor guard (4 button  
head screws) and the cord clamp, and set  
the front conveyor guard off to the side of the  
machine.  
11. Remove the rear conveyor end guards (4 but-  
ton head screws). The drum sander should  
now look similar to Figure 46.  
Figure 47. Chain removed from table by  
removing the master link.  
15. Loosen the conveyor belt from the rear  
adjustments, as shown in Figure 48.

17. Loosen the strain relief on the conveyor  
motor cord, and disconnect wiring inside the  
conveyor motor junction box.  
Note: Leave the front pillow bearing connect-  
ed to the bracket, but disconnect that bracket  
from the table.  
18. Remove the conveyor feed motor. The sand-  
er should now be disassembled as shown in  
Figure 49.  
Figure 51. Conveyor belt removed from table.  
21. Install the new belt and reassemble the drum  
sander by reversing the disassembly steps.  
Figure 49. Drum sander disassembled  
to Step 17.  
22. After reassembly, adjust the drums and pres-  
sure rollers to their proper settings. See Drum  
Adjustments on Page 33 and Pressure  
Roller Height on Page 36.  
19. Using four strong people (or a forklift w/  
straps), carefully lift the table off of the drum  
sander cabinet, as shown in Figure 50.  
Note: When removing the table, be careful  
with the ball thrust bearings located under  
the table elevation shafts (part #78 in the  
breakdown drawing), as they can be easily  
knocked onto the ground.
