SECTION 2: POWER SUPPLY
Availability
Before installing the machine, consider the avail-
ability and proximity of the required power supply
circuit. If an existing circuit does not meet the
requirements for this machine, a new circuit must
be installed. To minimize the risk of electrocution,
fire, or equipment damage, installation work and
electrical wiring must be done by an electrician or
qualified service personnel in accordance with all
applicable codes and standards.
Serious injury could occur if you connect
machine to power before completing setup
process. DO NOT connect to power until
instructed later in this manual.
Circuit Requirements
This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:
Nominal Voltage .................... 110V, 115V, 120V
Cycle..........................................................60 Hz
Phase........................................... Single-Phase
Power Supply Circuit ......................... 20 Amps
Electrocution, fire, or
equipment damage may
occur if machine is not
correctly grounded and
connected to the power
supply.
A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power sup-
ply circuit used for this machine must be sized to
safely handle the full-load current drawn from the
machine for an extended period of time. (If this
machine is connected to a circuit protected by
fuses, use a time delay fuse marked D.)
Full-Load Current Rating
The full-load current rating is the amperage a
machine draws at 100% of the rated output power.
On machines with multiple motors, this is the
amperage drawn by the largest motor or sum of all
motors and electrical devices that might operate
at one time during normal operations.
For your own safety and protection of
property, consult an electrician if you are
unsure about wiring practices or electrical
codes in your area.
Full-Load Current Rating at 120V ..... 15 Amps
The full-load current is not the maximum amount
of amps that the machine will draw. If the machine
is overloaded, it will draw additional amps beyond
the full-load rating.
Note: Circuit requirements in this manual apply to
a dedicated circuit—where only one machine will
be running on the circuit at a time. If machine will
be connected to a shared circuit where multiple
machines may be running at the same time, con-
sult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.
If the machine is overloaded for a sufficient length
of time, damage, overheating, or fire may result—
especially if connected to an undersized circuit.
To reduce the risk of these hazards, avoid over-
loading the machine during operation and make
sure it is connected to a power supply circuit that
meets the specified circuit requirements.

Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without yellow
stripes) is the equipment-grounding wire. If repair
or replacement of the power cord or plug is nec-
essary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Grounding & Plug Requirements
This machine MUST be grounded. In the event
of certain malfunctions or breakdowns, grounding
reduces the risk of electric shock by providing a
path of least resistance for electric current.
This machine is equipped with a power cord that
has an equipment-grounding wire and a grounding
plug. Only insert plug into a matching receptacle
(outlet) that is properly installed and grounded in
accordance with all local codes and ordinances.
DO NOT modify the provided plug!
Check with a qualified electrician or service per-
sonnel if you do not understand these grounding
requirements, or if you are in doubt about whether
the tool is properly grounded. If you ever notice
that a cord or plug is damaged or worn, discon-
nect it from power, and immediately replace it with
a new one.
GROUNDED
5-15 RECEPTACLE
Extension Cords
Grounding Prong
We do not recommend using an extension cord
with this machine. If you must use an extension
cord, only use it if absolutely necessary and only
on a temporary basis.
5-15 PLUG
Extension cords cause voltage drop, which can
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
Neutral Hot
Figure 3. Typical 5-15 plug and receptacle.
Any extension cord used with this machine must
be in good condition and contain a ground wire
and matching plug/receptacle. Additionally, it must
meet the following size requirements:
Minimum Gauge Size...........................12 AWG
Maximum Length (Shorter is Better).......50 ft.
SHOCK HAZARD!
Two-prong outlets do not meet the grounding
requirements for this machine. Do not modify
or use an adapter on the plug provided—if
it will not fit the outlet, have a qualified
electrician install the proper outlet with a
verified ground.

Cleanup
Site Considerations
The unpainted surfaces of your machine are
coated with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
This rust preventative works extremely well, but it
will take a little time to clean.
Workbench Load
Refer to the Machine Data Sheet for the weight
and footprint specifications of your machine.
Some workbenches may require additional rein-
forcement to support the weight of the machine
and workpiece materials.
Be patient and do a thorough job cleaning your
machine. The time you spend doing this now will
give you a better appreciation for the proper care
of your machine's unpainted surfaces.
Placement Location
Consider anticipated workpiece sizes and addi-
tional space needed for auxiliary stands, work
tables, or other machinery when establishing a
location for this machine in the shop. Below is
the minimum amount of space needed for the
machine.
There are many ways to remove this rust preven-
tative, but the following steps work well in a wide
variety of situations. Always follow the manufac-
turer’s instructions with any cleaning product you
use and make sure you work in a well-ventilated
area to minimize exposure to toxic fumes.
Before cleaning, gather the following:
•
•
•
•
Disposable rags
Cleaner/degreaser (WD•40 works well)
Safety glasses & disposable gloves
Plastic paint scraper (optional)
17"
Basic steps for removing rust preventative:
1. Put on safety glasses.
231/2
"
2. Coat the rust preventative with a liberal
amount of cleaner/degreaser, then let it soak
for 5–10 minutes.
Figure 5. Minimum working clearances.
3. Wipe off the surfaces. If your cleaner/degreas-
er is effective, the rust preventative will wipe
off easily. If you have a plastic paint scraper,
scrape off as much as you can first, then wipe
off the rest with the rag.
Children and visitors may be
seriously injured if unsuper-
vised around this machine.
Lock entrances to the shop
or disable start switch or
power connection to prevent
unsupervised use.
4. Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a quality

Bench Mounting
Assembly
Number of Mounting Holes ............................ 4
Dia. of Mounting Hardware Needed ..........5⁄16"
The cutterhead elevation crank, cord wraps, and
dust port must be installed in order to operate the
planer.
The base of this machine has mounting holes
that allow it to be fastened to a workbench or
other mounting surface to prevent it from moving
during operation and causing accidental injury or
damage.
To assemble planer loose parts:
1. Assemble cutterhead elevation crank by
snapping knob onto crank handle.
The strongest mounting option is a "Through
Mount" (see example below) where holes are
drilled all the way through the workbench—and
hex bolts, washers, and hex nuts are used to
secure the machine in place.
2. Remove black plastic lid from crank handle.
3. Align flat portion inside crank handle bore
with flat portion on elevation shaft, then place
crank assembly on elevation shaft.
4. Thread M5-.8 x 25 button head cap screw
and 5mm flat washer through crank (see
Figure 8) and into shaft. Tighten with 4mm
hex wrench. Do not over-tighten.

Dust Collection
This machine creates substantial amounts
of dust during operation. Breathing air-
borne dust on a regular basis can result in
permanent respiratory illness. Reduce your
risk by wearing a respirator and capturing
the dust with a dust collection system.

Recommended CFM at Dust Port: 250 CFM
Do not confuse this CFM recommendation with
the rating of the dust collector. To determine the
CFM at the dust port, you must consider these
variables: (1) CFM rating of the dust collector,
(2) hose type and length between the dust col-
lector and the machine, (3) number of branches
or wyes, and (4) amount of other open lines
throughout the system. Explaining how to cal-
culate these variables is beyond the scope of
this manual. Consult an expert or purchase a
good dust collection "how-to" book.

ice machine operator with a basic understanding
of how the machine is used during operation, so
the machine controls/components discussed later
in this manual are easier to understand.
able for planing.
2. Puts on safety glasses or face shield, a respi-
rator, and ear protection.
3. If workpiece is bowed, operator surface
planes workpiece on a jointer until one side
is flat. Doing so ensures that it sits solidly on
planer table during operation.
Due to the generic nature of this overview, it is
not intended to be an instructional guide. To learn
more about specific operations, read this entire
manual and seek additional training from expe-
rienced machine operators, and do additional
research outside of this manual by reading "how-
to" books, trade magazines, or websites.
4. Places workpiece on table with flat side
down. Positions front edge of workpiece far
enough under cutterhead assembly to set
depth of cut using cutterhead elevation scale
(see Depth of Cut on Page 20).
5. Correctly adjusts cutterhead height to

6. When all safety precautions have been taken,
turns planer ON.
7. Stands to one side of planer path to reduce
risk of kickback injuries, then, with flat surface
of workpiece facing down, feeds workpiece
into planer until infeed roller grabs it.
Eye injuries, respiratory problems, or hear-
ing loss can occur while operating this
tool. Wear personal protective equipment to
reduce your risk from these hazards.
8. Once workpiece is clear of outfeed roller,
operator measures workpiece thickness. If
further planing is required, operator adjusts
cutterhead height, then feed workpiece into
front of planer again.
9. Operator continues process until desired
thickness is achieved, then turns machine
OFF.
If you are not experienced with this type
of machine, WE STRONGLY RECOMMEND
that you seek additional training outside of
this manual. Read books/magazines or get
formal training before beginning any proj-
ects. Regardless of the content in this sec-
tion, Grizzly Industrial will not be held liable

Workpiece
Inspection
Wood Types
The species of wood, as well as its condition,
greatly affects the depth of cut the planer can
effectively take with each pass.
Some workpieces are not safe to use or may
require modification before they are. Before cut-
ting, inspect all workpieces for the following:
The chart in the figure below shows the Janka
Hardness Rating for a number of commonly
used species. The larger the number, the harder
the workpiece, and the less material should be
removed in any one pass for good results.
•
Material Type: This machine is only intend-
ed for workpieces of natural wood fiber
Attempting to use workpieces of any other
material that may break apart during opera-
tion could lead to serious personal injury and
property damage.
Note: The Janka Hardness Rating is expressed in
pounds of force required to embed a 0.444" steel
ball into the surface of the wood to a depth equal
to half the ball's diameter.
•
Foreign Objects: Inspect lumber for defects
and foreign objects (nails, staples, imbedded
gravel, etc,). If you have any question about
the quality of your lumber, DO NOT use it.
Remember, wood stacked on a concrete floor
can have small pieces of stone or concrete
pressed into the surface.

Planing Tips
Cutting Problems
•
Inspect your lumber for twisting or cupping,
and surface one face on a jointer if necessary
before planing workpiece.
Below is a list of wood characteristics you may
encounter when planing. The following descrip-
tions of defects will give you some possible
answers to problems you may encounter while
planing different materials. Possible solutions fol-
low the descriptions.
•
•
•
Scrape off all glue when planing glued-up
panels. Dried glue can quickly dull knives.
DO NOT plane more than one piece at a
time.
Chipped Grain
Problem: Usually a result of cutting against the
grain, planing lumber with knots or excessive
amount of cross grain, or using dull knives.
Never remove more than the recommended
amount of material on each pass. Only
remove a small amount of material on each
pass when planing wide or dense stock.
Solution: Decrease the depth of cut. Inspect
your lumber and determine if its grain pattern is
causing the problem. If the lumber does not show
substantial crossgrain, inspect your knives.
•
Support the workpiece on both ends. Get
assistance from another person if you are
planing long lumber, or use roller stands to
support the workpiece.
Fuzzy Grain
Problem: Usually caused by surfacing lumber
with too high of a moisture content. Sometimes
fuzzy grain is an unavoidable characteristic of
some woods, such as basswood. Fuzzy grain can
also be caused by dull knives.
•
Measure the workpiece thickness with cali-
pers to get exact results.
•
Carefully inspect all stock to make sure it is
free of large knots or foreign objects that may
damage your knives, cause kickback, or be
ejected from the planer.
Solution: Check the lumber with a moisture
meter. If moisture is greater than 20%, sticker the
lumber and allow it to dry. Otherwise, inspect the
knife condition.
•
•
When possible, plane equal amounts on
each side of the board to reduce the chance
of twisting or cupping.
Snipe
Use the entire width of the planer to wear
knives evenly. With narrow workpieces, alter-
nate between far left, far right, and the middle
of the table. Your knives will remain sharp
much longer.
Problem: Occurs when board ends have more
material removed than the rest of the board.
Usually caused when the workpiece is not prop-
erly supported as it goes through the machine. In
many cases, however, a small amount of snipe is
inevitable.
•
•
To avoid "chip marks," always plane WITH
the grain direction of the wood. Never plain
cross-grain or end-grain.
Solution: The best way to deal with snipe is by
planing lumber longer than your intended work
length and then cutting off the excess after plan-
ing is completed.
Plane ONLY natural wood fiber. Do not
plane wood composites or other materials
that could break up in the planer and cause
operator injury or damage to planer.
•
Always true cupped or warped stock on a
jointer before planing.

Pitch & Glue Build-up
Depth of Cut
Problem: Glue and resin buildup on the rollers
and cutterhead will cause overheating by decreas-
ing cutting sharpness while increasing drag in the
feed mechanism. The result can include scorched
lumber as well as uneven knife marks and chatter.
The planing depth on the Model G0790 is con-
trolled by the cutterhead elevation crank on top of
the planer. Turning the crank clockwise raises the
cutterhead; turning it counterclockwise lowers the
cutterhead.
Solution: Clean the rollers and cutterhead.
Chip Marks or Indentations
Elevation Crank
Problem: Chip indentation or chip bruising is the
result of wood chips not being thrown away from
the cutterhead and out of the machine. Instead
they are carried around the cutterhead, deposited
on the planed surface and crushed by the outfeed
roller. Chip indentations can be caused by a num-
ber of reasons, some of which are:
The elevation crank provides a simple and accu-
rate method for producing cuts of consistent
depth on multiple passes.
The pitch of the elevation leadscrew is 16 TPI
(threads per inch), meaning that every turn of the
crank will move the cutterhead 1⁄16". Using this as
a base, you can make passes with a depth of cut

Note: Any time you switch directions with the
cutterhead elevation crank, there will be a small
amount of backlash—so the first turn of the crank
after switching directions will be slightly less than
1⁄16". However, as long as you move the crank in
the same direction during the operation, backlash
will not be a factor.
•
•
Make sure planer knives are sharp.
Reduce depth of cut.
Although the correct depth of cut varies according
to wood hardness and workpiece width, we rec-
ommend a maximum depth of cut no more than
1⁄32". A series of light cuts will give better results
and put less stress on the planer than trying to
take off too much material in a single pass.

Elevation Scale
Feeding Workpiece
The depth of cut is read directly from the elevation
scale (see Figure 15) on the righthand column at
the front of the machine. The measurement indi-
cated by the red arrow is the effective thickness
of the board after planing.
The feed rate on this planer is automatically set
at 26 FPM. Infeed and outfeed rollers move the
workpiece through the planer while keeping it flat
and providing a consistent rate of movement.
To feed workpiece into planer:
Column
1. Place workpiece on table so it is perpendicu-
lar to cutterhead, with side to be planed fac-
ing up toward cutterhead.
Scale
Note: Boards more than 24" long should be
supported on both sides of planer.
Red Arrow
2. Lower cutterhead until depth bar (see Figure
16) just touches workpiece.
Figure 15. Positioning elevation scale.
Outfeed
Example: If you need to plane a board down to
1", simply make multiple passes (no greater than
the maximum depth of cut) until the cutterhead
elevation scale reads 1". A final pass at this set-
ting will create a 1" thick workpiece.
Depth
Bar
Note: The cutterhead elevation scale does not
provide a precise measurement and should only
be used for approximate measurements. If pre-
cise workpiece thicknesses are needed, use
calipers to ensure your workpieces meet your
standards.

7. Continue this process until desired thick-
ness is reached. Depth of cut indicator scale
shows approximate thickness of workpiece
after it has been cut. Use this indicator to
judge when thickness is approximately cor-
rect. For more precise applications, use a
caliper to measure workpiece thickness.

4. Turn planer ON.
5. With flat side of board facing down on table,
feed workpiece into front of planer, making
sure not to stand directly in front or behind
workpiece to reduce the risk of a kickback
injury.
— If cut is too deep and bogs down planer,
turn planer OFF immediately, allow it to
come to a complete stop, raise cutterhead,
remove workpiece, reduce depth of cut,
then repeat Step 5.
Note: Infeed and outfeed rollers will control
feed rate of workpiece as it passes through
planer. Do not push or pull on workpiece.

Knife Replacement
To reduce risk of shock or
accidental startup, always
disconnect machine from
power before adjustments,
maintenance, or service.
The cutterhead knives on Model G0790 are
extremely sharp. Accidental contact with
knives can result in severe cuts. Take great
caution whenever working with or around
cutterhead knives. Wear heavy leather
gloves to reduce risk of severe cuts.
Tools Needed
Qty
Hex Wrench 4mm.............................................. 1
Removing Knives
1. DISCONNECT MACHINE FROM POWER!
2. Remove (2) M5-.8 x 10 cap screws from
cutterhead guard, then remove guard (see
Figure 27).
To maintain accurate and consistent plan-
ing results, we do not recommend sharpen-
ing knives yourself. Instead, just replace
dull knives or have them professionally
sharpened.
Note: Cutterhead guard locks in place.
After removing cap screws, slide guard right
approximately 1⁄8" to release.
The knives on the Model G0790 Planer are
reversible and should always be reversed or
replaced as a matched set. To avoid downtime,
we recommend having an extra set of knives for
your planer. Once the cutterhead, gib, and knives
have been inspected and prepared, install the
knives.
Cutterhead
Guard
Before re-installing the knives, the cutterhead,
gib and knife must be inspected. Neglecting to
inspect these components may result in damage
to the planer.
Cap Screws
The condition of the knives on the Model G0790
will affect the precision of the cut. During opera-
tion, watch for the following signs of dulled knives.
Figure 27. Position of cutterhead guard prior to
disassembly.
•
Raised grain occurs as a result of dull knives
hammering at the surface of the wood.
•
A "fuzzy" appearance on the surface of the
wood occurs as a result of dull knives tearing,
rather than cutting the wood fibers.
•
•
Ridges occur as a result of nicks along the
knife edge.
Difficulty feeding the workpiece into the
planer.
If any of these signs become apparent during use,
the knives should be reversed or replaced.

Inspecting Cutterhead, Gib, and Knives
1. DISCONNECT PLANER FROM POWER!
2. Carefully clean the cutterhead with a rag and
with a flashlight, inspect the following:
•
•
Make sure the threaded screw holes do
not contain wood material or sawdust.
Make sure that the hex socket and the
threads of all cap screws are in good con-
dition. Replace if questionable.
Figure 30. Gib installation.
4. Carefully rotate cutterhead until second knife
slot is exposed.
•
•
Make sure any resin or glue buildup
on the cutterhead, gib, and knives is
removed so the knife and gib will sit flat
on the cutterhead.
5. Repeat Steps 2–3 for second knife, then
replace knife guard.
Make sure the knives are free of cracks.
If any cracks exist, replace both knives.

Replacing Motor
Brushes
Replacing &
Tensioning V-Belt
This motor is equipped with two long-life carbon
brushes. However, brush life expectancy is affect-
ed by motor loading. Regularly planing very wide,
dense boards or cutting too deeply will reduce
brush life.
The cutterhead is driven by a belt that is located
on the right-hand side of the motor and cutterhead
assembly (when facing the front of the machine).
The belt is very durable, but with extended use it
may begin to stretch and slip, indicating the need
for tightening or replacement.
Check brushes if motor loses power or becomes
noisy. Replace the carbon brushes when the motor
no longer reaches full power or if brushes mea-
sure less than 1⁄4" long (new brushes are 5⁄8" long).

Scale Calibration
Feed Rollers
Although correctly set at the factory, the scale can
be adjusted for accuracy if it becomes necessary.
The feed rollers rotate in bushing blocks that are
spring loaded. The feed rollers ride up on the
board so that the roller pressure is maintained.
If chips or sawdust build up between the bracket
and bushing block (see Figure 36), the amount
of roller vertical travel will be reduced, potentially
causing improper feeding of workpiece through
the machine.
Tools Needed
Qty
Phillips Screwdriver #2 ...................................... 1
Scrap Piece of Stock......................................... 1
Calipers ............................................................. 1
To reposition scale:
1. Plane scrap piece of stock until it is flat on
both sides and has even thickness along its
length.
Note: Turn scrap board over between each
pass to make surfaces parallel.

3. If there is a discrepancy between board thick-
ness and reading on elevation scale, loosen
the M6-1 x 12 Phillips head screw shown in
Figure 35, adjust position of red pointer to
indicate correct thickness, then re-tighten
screw.
Sawdust can get trapped between the
bushing block and the bracket.

Table Height
Adjustment
NOTICE
During next step, DO NOT let chain fall off
sprockets. It can be very difficult to return
chain to proper location on sprockets with-
out changing table adjustments.
The table and cutterhead are checked for paral-
lelism at the factory. However, over long periods
of use, parallelism may be affected. To restore
parallelism between the table and the cutterhead,
perform the following steps.
4. Loosen (2) M5-.8 x 10 cap screws on idler
bracket to loosen chain. Do not remove
chain.
Tools Needed
Hex Wrench 4mm.............................................. 1
Qty
Note: The goal in the next step is to adjust the
height of the table by rotating the leadscrew
sprockets at the corners of the base (see
Figure 38).
To adjust table height:
1. Plane a test piece of wood. Measure amount
of taper from front to back and side to side.
Determine which corner(s) of table need to
be adjusted.
