Safety Instructions For Power Tools  
9. USE PROPER EXTENSION CORD. Make  
sure your extension cord is in good condi-  
tion. Conductor size should be in accor-  
dance with the chart below. The amperage  
rating should be listed on the motor or tool  
nameplate. An undersized cord will cause  
a drop in line voltage resulting in loss of  
power and overheating. Your extension  
cord must also contain a ground wire and  
plug pin. Always repair or replace exten-  
sion cords if they become damaged.  
15. USE RECOMMENDED ACCESSORIES.  
Consult the owner’s manual for recom-  
mended accessories. The use of improper  
accessories may cause risk of injury.  
16. REDUCE THE RISK OF UNINTENTION-  
AL STARTING. On machines with magnet-  
ic contact starting switches there is a risk of  
starting if the machine is bumped or jarred.  
Always disconnect from power source  
before adjusting or servicing. Make sure  
switch is in OFF position before reconnecting.  
Minimum Gauge for Extension Cords  
17. CHECK DAMAGED PARTS. Before fur-  
ther use of the tool, a guard or other part  
that is damaged should be carefully  
checked to determine that it will operate  
properly and perform its intended function.  
Check for alignment of moving parts, bind-  
ing of moving parts, breakage of parts,  
mounting, and any other conditions that  
may affect its operation. A guard or other  
part that is damaged should be properly  
repaired or replaced.

SECTION 3: CIRCUIT REQUIREMENTS  
Amperage Draw  
Plug-Type  
We recommend using a NEMA-style 6-15 plug  
and outlet with the G0550 as shown in Figure 1a  
and an L6-20 plug and outlet for the G0551 as  
shown in Figure 1b. You may also “hard-wire”  
the planer directly to your panel, provided you  
place a disconnect near the machine. Check the  
electrical codes in your area for specifics on  
wiring requirements.  
The Model G0550/G0551 motor is wired to oper-  
ate at 220V only. The planer motors draw the fol-  
lowing amperage:  
Amperage Draw  
G0550 2 HP..........................................12 Amps  
G0551 3 HP..........................................18 Amps  
Circuit Breaker  
Use the following guidelines when choosing a cir-  
cuit breaker (circuit breakers rated any higher are  
not adequate to protect the circuit):  
Circuit Breaker  
G0550 ........................................15 Amp, 2 Pole  
G0551 ........................................20 Amp, 2 Pole

Circuit Capacity  
Extension Cords  
Always check to see if the wires in your circuit are  
capable of handling the amperage draw from  
your machine, as well as any other machines that  
could be operating on the same circuit. If you are  
unsure, consult a qualified electrician.  
220V Operation  
We do not recommend the use of extension cords  
on 220V equipment. Instead, arrange the place-  
ment of your equipment and the installed wiring to  
eliminate the need for extension cords.  
If the circuit breaker trips or the fuse blows regu-  
larly, your machine may be operating on a circuit  
that is close to its amperage draw capacity.  
However, if an unusual amperage draw does not  
exist and a power failure still occurs, contact a  
qualified electrician.  
If you find it absolutely necessary to use an  
extension cord at 220V with your Grizzly Planer:  
Make sure the cord is rated for Standard  
Service (grade S) or better.  
The extension cord must also contain a  
ground wire and plug prong.  
Use at least a 16 gauge cord if the cord is 50  
feet long or less.  
Grounding  
Use at least a 14 gauge cord if the cord is  
between 51-100 feet.  
Electrocution or a fire can  
result if the machine is  
not grounded correctly.  
Make sure all electrical  
circuits are grounded. DO  
NOT use the machine if it  
is not grounded.  
In the event of an electrical short, grounding  
reduces the risk of electric shock by providing a  
path of least resistance to disperse electric cur-  
rent. This tool is equipped with a power cord that  
has an equipment-grounding prong. The outlet  
must be properly installed and grounded in accor-  
dance with all local codes and ordinances.

Site Considerations  
Clean Up  
Floor Load  
The unpainted surfaces are coated with a waxy  
oil to protect them from corrosion during ship-  
ment. Remove this protective coating with a sol-  
vent cleaner or citrus-based degreaser such as  
Grizzly’s G7895 Degreaser. To clean thoroughly,  
some parts may need to be removed. For opti-  
mum performance from your machine, make  
sure you clean all moving parts or sliding  
contact surfaces that are coated. Avoid chlo-  
rine-based solvents as they may damage painted  
surfaces should they come in contact.  
The Model G0550 weighs 410 lbs and has a 25"  
x 25" footprint. The Model G0551 weighs 450 lbs  
and has a 21" x 21" footprint. Most commercial  
floors are suitable for the machine. Some resi-  
dential floors may require additional reinforce-  
ment to support both the machine and operator.  
Working Clearances

Cutterhead Locks  
Your safety is important! Please follow the  
warnings below during this entire section:  
There is a cutterhead lock knob on each side of  
the planer that must be loosened before adjusting  
the height. Once the height has been set, tighten  
the lock knobs. See Figure 15.  
Damage to your eyes, lungs, and ears  
could result from failure to wear safety  
glasses, a respirator, and hearing protec-  
tion while using this machine.

Power Feed  
Handwheel  
The power feed can be set for two feed rates—16  
FPM and 20 FPM. While the planer is running the  
feed rate can be changed by pulling the feed con-  
trol knob (Figure 16). Press the knob in towards  
the machine for 20 FPM and pull the knob out for  
16 FPM. When the control knob is in the center  
position, the power feed is in neutral.  
Turn the handwheel to raise or lower the cutter-  
head, according to the workpiece thickness.  
Each complete revolution of the handwheel  
moves the table by 532" (4mm).  
Make sure the height scale is properly adjusted  
before making a cut. It is always a good idea to  
run a test piece through the planer and compare  
the thickness of the workpiece to the scale read-  
ing.  
Depth Limiter  
The depth limiter, shown in Figure 17, controls  
1
the maximum depth of cut to 8". To avoid  
mechanical damage to the planer and workpiece  
do not remove the depth limiter.

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.

Anti-Kickback  
Wood Species  
The species of wood, as well as its condition,  
have a dramatic effect on planing ability. The  
harder the wood (as illustrated by its shear  
strength), the more difficult it will be to plane. A  
brief listing of common hard and soft woods in  
relation to their shear strengths and planing diffi-  
culty is listed below.  
The anti-kickback fingers hang from a rod sus-  
pended across the front of the cutterhead casting.  
Check the fingers to ensure that they swing freely  
and easily. See Figure 18.  
DO NOT apply oil or other lubricants to the  
anti-kickback fingers. Oil or grease will  
attract dust and restrict movement of the  
fingers, which could result in damage to  
your workpiece, the planer, or possibly  
serious injury to the operator.

5. Any other condition that could hamper the  
safe operation of this machine.  
Table  
Projectiles from the  
machine could cause  
serious eye injury. Wear  
safety glasses at all  
times.  
The table and other non-painted surfaces on your  
machine should be protected against rust and pit-  
ting. Wiping the table clean after every use  
ensures that moisture from wood dust does not  
remain on bare metal surfaces.  
Tables can be kept rust-free with regular applica-  
tions of products like SLIPIT® or Boeshield® T-9.  
For long term storage you may want to consider  
products like Kleen Bore's Rust Guardit™.

V-Belts  
Squeeze the V-Belts at their midpoints with mod-  
erate finger pressure. You should be able to  
deflect each V-Belt about 3/4". Belts will rarely be  
too tight, but will sometimes be too loose.  
To ensure optimum power transmission from the  
motor to the blade, the V-belts must be in good  
condition (free from cracks, fraying and wear).  
Check the V-belts at least every 3 months; more  
often if the planer is used daily.  
To tension the V-Belt:  
1. Disconnect the machine from the power  
source!  
Make sure that the motor pulley and cutterhead  
pulley are aligned and the V-Belts are properly  
tensioned.  
2. Insert a wooden lever between the motor  
mount and the top of the planer as shown in  
Figure 20.  
To align the V-Belt:  
1. Disconnect the machine from the power  
source!  
2. Remove the V-Belt cover.  
3. Loosen the bolts that mount the motor to the  
motor mount bracket.  
4. Adjust the position of the motor until the pul-  
leys are in line, and check the alignment with  
a straightedge as shown in Figure 19.  
Loosen These Bolts  
Figure 20. Tensioning Belt.  
3. Loosen the two bolts that hold the motor pul-  
ley assembly to the planer (Figure 19).  
4. Lift the motor assembly with the wooden  
lever until the belt is tensioned correctly.  
5. Hold the motor in place and secure the bolts  
loosened in step 3.  
6. Squeeze the belts to check the tension and  
repeat steps 2-5 if necessary.

Gearbox  
Lubrication  
Since all bearings are sealed and permanently  
lubricated, simply leave them alone until they  
need to be replaced. DO NOT lubricate them.  
The gearbox is located just behind the handwheel  
on the right side of the planer. The gearbox trans-  
fers power from the belt-driven cutterhead to the  
power feed rollers. The two-speed transmission  
is controlled by a push/pull lever on the right side  
of the planer. When engaged, the power feed  
rollers will move lumber through the planer at  
either 16 or 20 feet-per-minute. The center lever  
position is neutral.  
The following is a list of features and parts  
that need lubrication:  
Columns/Lead Screws—The four columns  
should be lubricated with light machine oil once a  
week. The four lead screws should be lubricated  
with general purpose grease once a month. See  
Figure 22.  
To inspect the gearbox:  
1. Loosen the socket head cap screw on the  
gearbox cover, and gently pull the cover off  
the roll pins that hold it in place.  
2. Check the bolts that hold the sprockets in  
place. Inspect the drive chains to ensure that  
the retaining clips are in place. Replace the  
clips if necessary. See Figure 21.

Worm Gear—The worm gear should be inspect-  
ed monthly and lubricated when needed.  
Remove the worm gear box to inspect. See parts  
diagram for location.  
Drive Chain—The drive chain should be inspect-  
ed and lubricated monthly. Check the sprocket,  
the chain and the cotter pin during inspection.  
Use a general purpose grease. Some chains will  
have master links instead of cotter pins.  
Chain—The table height adjustment chain  
should be inspected monthly and lubricated when  
needed. A good quality bicycle chain lubricant  
works well for periodic lubrication.  
Feed Rollers—The infeed/outfeed pressure  
setscrews double as lubrication ports for the  
rollers. See Figure 25. Add 1-2 drops of light  
machine oil to all ports before each use. Daily  
lubrication of the feed rollers is crucial to the oper-  
ation of your planer. Lubricate before start-up.  
Apply a light oil, making sure that the lubricant  
penetrates the bearing.  
Gear Box—Gear box oil should be drained after  
the first 20 hours of operation. See Figure 23 &  
24. Replace with 80W-90 gear oil. Inspect levels  
periodically and change yearly. Replace gear oil  
more frequently under heavy use. Fill until oil  
reaches the top of the filler plug port for correct oil  
level.

Planing Difficulties  
Snipe can be minimized by proper adjustment of  
the planer components, but complete removal of  
snipe is extremely unlikely. More likely, you will  
be able to reduce it to a tolerance of .002". If  
snipe under that level is a problem, consider plan-  
ing lumber longer than your intended work length  
and cut off the excess after planing is completed.  
The species of wood, as well as condition, will  
affect planing ability. The harder the wood, the  
more difficult it will be to plane. Below, we have  
included below, a list of wood characteristics you  
may encounter when planing. The following  
descriptions of defects will give you some possi-  
ble answers to problems you may encounter  
while planing different materials. Possible solu-  
tions follow the descriptions.  
Uneven Knife Marks—Uneven knife marks can  
occur when the chipbreaker is set too high.  
Inspect cutterhead bearings if re-adjustment of  
the chipbreaker fails to remedy the situation.  
Chatter Marks—Usually caused by incorrect  
chipbreaker and pressure bar setting heights.  
Chatter marks can also be caused by running a  
narrow wood piece through the planer at either  
the right or left end of the cutterhead. Chatter, like  
uneven knife marks, will show in the form of a  
''washboard'' look. Chatter marks are more likely  
to be inconsistent in appearance than uneven  
knife marks.  
Chipped Grain—Usually a result of cutting  
against the grain, or planing wood with knots or  
excessive amount of cross grain. Chipped grain  
can also be caused by dull knives or misaligned  
chipbreaker. Often, chipped grain can be avoided  
by slowing down the feed rate and by taking shal-  
low cuts. If those options do not work, inspect  
your lumber and determine if its grain pattern is  
causing the problem. If the wood does not show  
substantial crossgrain, inspect your knives for  
sharpness and inspect the chipbreaker for proper  
alignment. See the Adjustment Section.  
Wavy Surface—Caused by poor knife height  
adjustment, a wavy surface appears when one  
knife is taking deeper cuts than the rest of the  
knives. Remedy by resetting the knives to a toler-  
ance within 0.003" of one another.  
Fuzzy Grain—Usually caused by surfacing lum-  
ber with too high of a moisture content.  
Sometimes fuzzy grain is a characteristic of some  
woods, such as basswood. Fuzzy grain can also  
be caused by dull knives or an incorrect grinding  
bevel. Check with a moisture meter. If moisture is  
greater than 20%, sticker the wood and allow to  
dry. Otherwise, inspect knife condition.  
Pitch & Glue Build-up—Glue and resin build-up  
on the rollers and cutterhead will cause overheat-  
ing by decreasing cutting sharpness while  
increasing drag in the feed mechanism. The  
result can include scorched lumber as well as  
uneven knife marks and chatter.  
Glossy Surface—Usually caused by dull knives  
taking shallow cuts at a slow feed speed. Surface  
gloss will usually be accompanied by overheat-  
ing. Often, lumber will be scorched and eventual-  
ly damage to knives will occur. If knives are sharp  
on inspection, increase feed speed or cutting  
depth.  
Chip Marks—Occur when chips are not properly  
expelled from the cutterhead. The knives catch  
the chips and drag them across the lumber being  
planed. Chips tend to be random and non-uni-  
form (as compared to chipped grain). Can be  
caused by exhaust blockage or too much room  
between the cutterhead and chip deflector. Using  
a dust collection system in combination with the  
planer can help reduce chip marks. Inspect the  
chip deflector and readjust (as described earlier  
in the text).  
Snipe—Occurs when board ends have more  
material removed than the rest of the board.  
Usually caused when one or both of the bed  
rollers are set too high. Can also be caused by  
the chipbreaker or pressure bar being set too  
high. However, small amount of snipe is  
inevitable.

SECTION 8: SERVICE ADJUSTMENTS  
Gauge Blocks  
Always  
disconnect  
power to the machine  
before performing ser-  
vice adjustments. Failure  
to do this may result in  
serious personal injury.  
Before attempting to adjust the table, you will  
need to construct a gauge block. See Figure 26.  
Do not use common 2x4 material. Use a hard  
wood material like maple or oak. A pattern for this  
gauge block has been provided for you on page  
48 of this manual.  
About Service  
A good alternative is to use a Rotocator Figure  
27. Use the Rotocator whenever the instructions  
call for use of the gauge block or feeler gauge.  
Refer to the current Grizzly catalog for rotocators.  
This section is designed to help the operator with  
adjustments that were made at the factory and  
that might also need to be made during the life of  
the machine.  
This section is provided for your convenience—it  
is not a substitute for the Grizzly Service  
Department. If any adjustments arise that are not  
described in this manual, then feel free to call the  
Grizzly Service Department at (570) 546-9663.  
Similarly, if you are unsure of how to perform any  
procedure in this section, the Grizzly Service  
Department will be happy to guide you through  
the procedures or help in any other way.

0.016", go to step 5.  
Table Adjustment  
If the gap difference from one side to the other is  
greater than 0.016", the table raising chain under  
the planer base will need to be adjusted. Please  
call our Customer Service number for chain  
adjustment instructions.  
It is important that the cutterhead is parallel to the  
table to plane stock perfectly square.  
To check the table alignment:  
1. Disconnect the machine from the power  
source!  
To adjust for gap differences:

raised to correct the gap.  
7. Locate the two cap screws in the table cast-  
ing for each of the columns. See Figure 29.  
Loosen both sets of cap screws for each col-  
umn on the side you wish to adjust.  
3. Turn the handwheel to raise the table until  
the block barely touches the cutterhead  
body. The block should not be touching  
the knives. See Figure 28.  
4. Slide the block toward the opposite side of  
the cutterhead. Use a feeler gauge to mea-  
sure the width of the gap, if any, between the  
top of the block and the bottom of the cutter-  
head. If there is a gap, make a note, reading  
the distance from the feeler gauge.  
5. If the block wedges tightly between the table  
and cutterhead when shifting from one side  
to the other, repeat steps 1 through 3 above,  
but start from the opposite end of the cutter-  
head.  
Figure 29. Cap screws for column adjustment.  
8. Push down or pull up the table in the desired  
direction. Hold the table in position and  
retighten the cap screws.  
9. Recheck the table to cutterhead parallelism  
again. Repeat steps 1- 8 until the deviation  
is less than 0.004".

4. Measure the board again and compare your  
results with the scale. If there is a discrepan-  
cy, loosen the scale adjustment screw and  
correct the position. See Figure 30.  
Thickness Scale  
The thickness scale, located below the hand-  
wheel, can be adjusted for accuracy. However,  
material must be run through the machine to  
adjust the thickness scale. Make certain you have  
followed the directions in the Operations Section  
for test running before attempting to make these  
adjustments.  
To adjust the scale:  
1. Adjust the cutterhead height to the approxi-  
mate thickness of your test lumber. Measure  
the lumber with calipers to determine its  
exact thickness.

2. Move the cutterhead to 16" under the thick-  
ness of your lumber and feed your test board  
through the planer.  
3. Turn the handwheel one half rotation and run  
the board through once more. Turn the board  
over and repeat.

Knife Inspection  
The Model G0550/G0551 Planer has a three-  
knife cutterhead. The cutterhead is located in the  
head casting and rotates on two sealed bearings.  
No lubrication is needed for the life of the bear-  
ings.  
Because of normal use and wear, the knives  
must be periodically sharpened, replaced or  
adjusted. Adjustment from the factory must also  
be checked prior to use due to possible move-  
ment during shipment.  
Figure 31. Using the feeler gauge to  
measure the gap.  
To inspect the knives:  
5. The variation between one side and the other  
should not be greater than 0.004". Repeat  
steps 1-4 on the other two knives. Again, the  
variation between all three knives should not  
be greater than 0.004".  
1. Disconnect the machine from the power  
source!  
2. Lower the table and place the gauge block or  
a Rotocator under one end of the cutterhead.  
Once you have completed inspection on all three  
knives, you will able to determine whether or not  
there is a need to adjust the knives in the cutter-  
head. Proceed to the appropriate section,  
depending upon whether you are using the jack  
screws or the springs.  
3. Remove the V-Belt cover and carefully rotate  
the belts to turn the cutterhead until the first  
knife is at bottom dead center. Adjust the cut-  
terhead height until the knife barely touches  
the top of gauge block. Note—Rock the cut-  
terhead back and forth to determine bottom  
dead center.  
When making adjustments, all three knives  
must be adjusted the same. DO NOT adjust  
one knife without adjusting the others as  
well. Improper knife height adjustment can  
result in damage to knives, poor planer per-  
formance and possible operator injury.  
4. Slide the gauge block to the opposite side of  
the cutterhead and check the same knife,  
rocking back and forth to determine bottom  
dead center.  
— If the knife does not contact the gauge  
block, use a feeler gauge to determine  
the difference between one side and the  
other. See Figure 31.  
NOTICE  
— If the knife bottoms out on the gauge  
block, repeat steps 1-3, but start on the  
opposite side of the cutterhead.  
Always adjust the thickness scale after  
adjusting the knives.

Knife Sharpening  
Knife Setting  
The process of setting the knives in the cutter-  
head will come into play whenever you sharpen  
or replace, or after determining that setting is nec-  
essary during the initial setup.  
For the best results, it is best to have planer  
knives sharpened by a professional sharpening  
service which has the grinding and measurement  
equipment to assure that the knife cutting geom-  
etry is maintained at optimum levels. Knife sharp-  
ening is a procedure that requires some care and  
precision, otherwise, a set of blades can be easi-  
ly ruined. Knives should always be ground as a  
set so they can be properly matched. Unequal  
material removal can result in an unbalanced cut-  
terhead which can affect not only planing surface  
quality but ultimately the life of the cutterhead  
bearings.  
The knives lock into the cutterhead with wedge  
type gibs. Springs under each knife provide an  
upward pressure to help ease the setting  
process. Jack screws under the knives allow fine  
tuning to help in the setting process.  
To set the knives:  
1. Disconnect the machine from the power  
source!  
Your planer knives can be sharpened by a blade  
hone. See the “Aftermarket Accessories” sub-  
section at the back of this manual for more infor-  
mation.  
2. Remove the upper cover to expose the cut-  
terhead.  
3. Choose a knife to begin with and loosen the  
gib bolts just enough until the springs push  
the knife upward.  
Figure 32 illustrates the features of the cutter-  
head that are mentioned in this section.

4. Place the knife setting jig over the knife on  
the cutterhead as shown in Figure 33. The  
knife setting jig will push the knife into posi-  
tion in the cutterhead.  
Chip Breaker  
The chip breaker is located on the top side of the  
planer and extends down around the front of the  
cutterhead. Its function is to prevent tear-out or  
deep, unregulated gouging as the knives remove  
material. The chip breaker works by breaking the  
woodchips as they are being cut by the cutter-  
head. The chip breaker also deflects and expels  
the woodchips away from the surface of the  
board and out of the planer.  
To check the chipbreaker:  
1. Disconnect the machine from the power  
source!  
Figure 33. Proper knife setting jig placement.  
2. Ensure that the knives are properly adjusted.  
5. While holding the position of the knife setting  
jig, adjust the jack screws, located on each  
end of the knife, until they make contact with  
the bottom of the knife.  
3. Place the gauge block on the table directly  
under the cutterhead.  
4. Using a 1mm feeler gauge between the  
gauge block and the cutterhead, raise the  
table until one of the knives just touches the  
feeler gauge. Rotate the cutterhead by turn-  
ing the V-belts to be sure the knife is at bot-  
tom dead center.  
6. While holding the position of the knife setting  
jig, tighten the gib bolts down again in the  
cutterhead (Figure 34). Tighten the bolts  
evenly from the middle, working toward the  
ends.  
5. Lock the table by tightening the table lock  
7. Repeat these steps for the other two knives.  
knobs.  
6. Remove the feeler gauge and slide the  
gauge block under the chip breaker. See  
Figure 35. The chip breaker should just  
touch the top of the gauge block. Slide the  
gauge block to the opposite end of the chip  
breaker and check it in the same manner.

Feed Roller Height  
The infeed and outfeed rollers move the lumber  
through the planer, and press the lumber flat  
against the planer table.  
Set the infeed and outfeed rollers to 0.02"-0.04"  
below the cutterhead knife edge at bottom dead  
center.  
To check roller height:  
Figure 35. Gauge block under chip breaker.  
1. Disconnect the machine from the power  
source!  
To adjust the chip breaker:  
2. Lower the table so the gauge block will fit

source!  
under one side of the infeed roller.  
3. Raise the table until the gauge block barely  
touches the infeed roller. See Figure 37. Do  
not change the position of the table.  
2. If an adjustment is necessary, loosen the  
locknuts and turn the setscrews. See Figure  
36. Stop turning when the bottom of the chip  
breaker just touches the gauge block.  
4. Slide the gauge block over so it is under the  
edge of one of the knives. Turn the cutter-  
head until one of the knives is at bottom  
dead center over the gauge block.  
3. Tighten both locknuts.  
5. Measure the clearance between the top of  
the gauge block and the edge of the knife  
with a feeler gauge. Note the measurement  
indicated on the feeler gauge.

6. Repeat steps 1-5 for the opposite side of the  
Bed Rollers  
roller. Repeat all steps for the outfeed roller.  
Feeler gauge measurement should be between  
0.02"- 0.04"on the infeed and outfeed roller at  
bottom dead center.  
The bed rollers ease stock movement through  
the planer. The height of the bed rollers will vary  
depending on the types of wood you will be plan-  
ing. When planing rough stock, set the rollers  
slightly high to keep the lumber from dragging  
along the bed; however, snipe may be unavoid-  
able. Smooth lumber should be planed with the  
rollers set just above the plane of the table. This  
will minimize snipe.  
To adjust roller height:  
1. Remove the drive chain cover to access the  
roller adjustments on the drive chain side of  
the planer. A single socket head cap screw  
holds the drive chain cover on. The belt side  
adjustments are already accessible.  
To adjust the bed rollers:  
2. Loosen the roller adjustment check nuts and  
turn the roller height setscrews to change the  
height of the roller as needed. See Figure  
38.  
1. Ensure that power is disconnected and lay a  
high quality straightedge across both table  
rollers. Use a try square to keep the straight-  
edge perpendicular to the table.  
3. Check the roller height according to the  
above instructions. Continue turning the  
setscrew until the roller is properly adjusted.  
2. Use a feeler gauge to measure the clearance  
between the bottom of the straight edge and  
the table. Ideal clearance is between 0.006"  
and 0.002". Measure in several places. This  
measurement must be consistent across the  
entire table. See Figure 39.  
4. When the roller is set in the correct position,  
retighten the check nuts you loosened in  
step 2 above.  
5. Check your settings one last time and repeat  
steps 1-4 if necessary.

3. Loosen the setscrews on both sides of  
each bed roller. See Figure 40.  
Feed Roller Pressure  
To be effective, the infeed and outfeed rollers  
must put pressure on the workpiece as it feeds  
through the planer. Too little pressure results in  
slipping boards, too much pressure results in  
jamming.  
Setscrews  
Setscrews  
Experiment with the best pressure settings for  
your work situations. Some rough cut lumber will  
feed through with relatively few problems, while  
other lumber will have more difficulty.  
Adjusting roller pressure does not affect height.  
To adjust roller pressure:  
Figure 40. Adjusting bed roller height.  
1. Disconnect the machine from the power  
source!  
4. Use a wrench to turn the eccentric shafts that  
adjust roller height. Stop turning when the  
table rollers are at the proper height.  
2. Ensure that knives and feed rollers are set  
correctly.  
5. Once your roller heights are correct, retight-  
en all the setscrews.  
3. Unscrew the three regular pressure  
setscrews on top of the planer body. See  
Figure 41.  
6. Check the height of the table rollers. Repeat  
steps 1-5 until the bed rollers are properly  
set.  
Regular Pressure Setscrews  
7. Spin the bed rollers to ensure free move-  
ment.

Chip Deflector  
4. Remove the springs that are in the setscrew  
holes. See Figure 42.  
The chip deflector keeps chips from falling onto  
the outfeed roller. It is the orange plastic plate  
located under the top cover.  
5. Check for any dirt or grit, and clean the  
springs and setscrews if dirty.  
6. Screw the three regular-pressure setscrews  
back in until they are flush with the top of the  
head casting.  
The beveled edge of the chip deflector should be  
properly adjusted according to your dust collec-  
tion setup. However, if the chip deflector is set too  
close to the knives, the rotating cutterhead may  
pull it in and destroy it.  
7. Screw the light pressure setscrew (Figure  
1
42) until it is approximately 4" above the  
head casting. The feed chain applies addi-  
tional tension to the right side of the outfeed  
roller, so the pressure added by the setscrew  
need not be as high.  
To adjust the chip deflector:  
1. Disconnect the machine from the power  
source!  
2. Loosen the three deflector mounting bolts.  
See Figure 43. Make sure the beveled edge  
of the deflector faces the cutterhead.
