Additional Safety Instructions For The  
Portable Planer  
1. Ensure that the machine is firmly secured  
6. Position yourself so as not to get caught  
(pinned) between the lumber and another  
obstruction during the planing operation.  
Also, ensure that there is sufficient clear-  
ance for the material being fed.  
to a bench or table before use.  
2. Always be aware of the condition of the  
wood you are planing. Pay particular atten-  
tion to knots, splits, and other potential  
areas where the grain may be getting  
ready to separate.  
7. Keep hands and fingers away from moving  
parts and away from the infeed and outfeed  
section of the planer. Do not reach into the  
machine at any time for any reason without  
first turning the switch off, pulling the elec-  
trical plug and after the machine has come  
to a full stop.  
3. Perform machine inspection and mainte-  
nance services regularly.  
4. Make sure the planer knives are sharp,  
balanced, and set correctly and securely.  
Operate planer only with both knives in the  
cutterhead.  
8. Any glued-up stock must be completely set  
up and dry before planing.  
5. Do not plane any man-made composites  
such as plywood, hardboard, particle  
board, fiber board, flake board, fiberglass  
and/or any other material other than solid,  
natural wood fiber.  
9. Never leave the planer running unattended.  
10. Habits – good and bad – are hard to break.  
Develop good habits in your shop and safe-  
ty will become second-nature to you.  
Operating this equipment has the potential  
to propel debris into the air which can  
cause eye injury. Always wear safety glass-  
es or goggles when operating equipment.  
Everyday glasses or reading glasses only  
have impact resistant lenses; they are not  
safety glasses. Be certain the safety glass-  
es you wear meet the appropriate standards  
of the American National Standards  
Institute (ANSI).  
Like all power tools, there is danger associ-  
ated with the Model G8794 Portable Planer.  
Accidents are frequently caused by lack of  
familiarity or failure to pay attention. Use  
this tool with respect and caution to lessen  
the possibility of operator injury. If normal  
safety precautions are overlooked or  
ignored, serious personal injury may occur.

SECTION 2: CIRCUIT REQUIREMENTS  
110V Operation  
Grounding  
The Model G8794 is wired for 110/120V, single  
phase operation only. The 2 HP motor will draw  
15 amps at 110V. If you operate this planer on  
any circuit that is already close to its capacity, it  
might blow a fuse or trip a circuit breaker.  
However, if an unusual load does not exist and a  
power failure still occurs, contact a qualified elec-  
trician or our service department.  
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 hav-  
ing an equipment-grounding conductor. See  
Figure 1. The outlet must be properly installed  
and grounded in accordance with all local codes  
and ordinances.  
This equipment must be grounded. Verify  
that any existing electrical outlet and circuit  
you intend to plug into is actually ground-  
ed. If it is not, it will be necessary to run a  
separate 12 A.W.G. copper grounding wire  
from the outlet to a known ground. Under  
no circumstances should the grounding pin  
from any three-pronged plug be removed.  
Serious injury may occur.  
Fusing  
A 20-amp fuse or circuit breaker should be used  
when fusing this combination sander. Circuits  
rated any higher are not adequate to protect the  
motor from power surges.  
Equipment returned to us for service that shows  
evidence of being over-fused will be repaired or  
replaced totally at the customer’s expense,  
regardless of the present warranty status.  
Extension Cords  
If you find it necessary to use an extension cord  
with the Model G8794, make sure the cord is  
rated Hard Service (grade S) or better. Refer to  
the chart in the standard safety instructions to  
determine the minimum gauge for the extension  
cord. The extension cord must also contain a  
ground wire and plug pin. Always repair or  
replace extension cords when they become worn  
or damaged.

The G8794 is a relatively heavy machine (85  
lbs. shipping weight). DO NOT over-exert  
yourself while unpacking or moving your  
machine – get assistance. In the event that  
your planer must be moved up or down a  
flight of stairs, be sure that the stairs are  
capable of supporting the combined weight  
of people and the machine. Serious person-  
al injury may occur.  
In the event that any non-proprietary parts are  
missing (e.g. a nut or a washer), we would be  
glad to replace them, or, for the sake of expedi-  
ency, replacements can be obtained at your local  
hardware store.

Clean up  
Site Considerations  
The table surface has a protective film on it which  
must be peeled away. The cutterhead surfaces  
are coated with a waxy oil to protect them from  
corrosion during shipment. Remove this protec-  
tive coating with a solvent cleaner or citrus-based  
degreaser such as Grizzly’s G7895 Degreaser.  
The cutter knives are extremely sharp, use great  
caution when cleaning those areas. Avoid chlo-  
rine-based solvents as they may damage painted  
surfaces should they come in contact. Always fol-  
low the usage instructions on the product you  
choose for clean up.  
The Model G8794 is designed to be portable.  
There is a carry handle located on the top of the  
planer, as well as handles on both sides of the  
planer to aid in lifting and moving. Before moving  
the planer, fold the extension wings up and  
ensure that the power cord is disconnected and  
stored beneath the wing on the cord storage loop.  
1. Working Clearances: Consider existing  
and anticipated needs, size of material to  
be processed through each machine, and  
space for auxiliary stands, work tables or  
other machinery when establishing a loca-  
tion for your planer.  
Many of the solvents commonly used to clean  
machinery can be highly flammable, and toxic  
when inhaled or ingested. Always work in  
well-ventilated areas far from potential ignition  
sources when dealing with solvents. Use care  
when disposing of waste rags and towels to  
be sure they do not create fire or environmen-  
tal hazards. Keep children and animals safely  
away when cleaning and assembling this  
machine.  
2. Lighting and Outlets: Lighting should be  
bright enough to eliminate shadow and pre-  
vent eye strain. Electrical circuits should be  
dedicated or large enough to handle  
amperage requirements. Outlets should be  
located near each machine so power or  
extension cords are clear of high-traffic  
areas. Observe local electrical codes for  
proper installation of new lighting, outlets,  
or circuits.  
Do not use gasoline or other petroleum-based  
solvents to remove this protective coating.  
These products generally have low flash  
points which makes them extremely flamma-  
ble. A risk of explosion and burning exists if  
these products are used. Serious personal  
injury may occur.  
The cutterhead knives on the G8794 planer are  
extremely sharp. Merely brushing your finger  
along the edge can result in a severe cut. Take  
extreme caution when doing any of the adjust-  
ments involving the cutterhead knives. Wear  
thick gloves anytime it is necessary to manu-  
ally rotate the cutterhead assembly.

SECTION 4: ASSEMBLY  
Chip Deflector  
For your safety and proper machine operation,  
ensure that the chip deflector is secured before  
use. The chip deflector directs wood chips away  
from the cutterhead during operation and covers  
the cutterhead and feed rollers for operator safe-  
ty. To secure the chip deflector:  
1. Align the chip deflector with the two bolts  
mounted at the exit side of the planer.  
2. Set chip deflector in place and use two wing  
nuts and washers to secure in place. See  
Figure 2.  
Figure 3. Mounting handle.  
Mounting to Bench  
Mounting Studs  
The planer can be directly mounted to a bench or  
table top, or to a Shop Fox® Deluxe Tool Table for  
increased stability during planing. Use the mount-  
ing holes shown in Figure 4, using the appropri-  
ate fasteners.  
Figure 2. Chip deflector mounting studs.  
Handle Assembly  
Attach the handle assembly to the shaft protrud-  
ing out of the top of the planer. Align the flat  
inside the handle bore with the flat on the shaft.  
Insert the M5-.8 x 20mm cap screw. Do not over  
tighten.  
Mounting Holes

SECTION 5: CONTROLS  
On-Off Switch  
Depth-Of-Cut  
The on-off switch is located on the front of the  
planer. See Figure 5. The switch has a key  
which, when removed, allows the switch to be  
locked in the “off” position. To access the locking  
feature, push the switch to the OFF position and  
pull the switch key out. Should the key be  
removed when the planer is ON, it can still be  
turned OFF, but will not be able to be restarted  
until the key is replaced.  
The planing depth is controlled by the crank han-  
dle on top of the planer. Turning the handle clock-  
wise raises the cutterhead and counter-clockwise  
lowers the cutterhead. See Figure 6. Depth-of-  
cut is read directly from the inch/millimeter scale  
located on the top, right side of the planer. One  
complete turn of the handle raises or lowers the  
5
cutterhead approximately 64'' (2mm). The range  
3
of material thickness that can be planed is 16'' -  
6'' (5mm - 1152mm).  
The maximum depth-of-cut varies according to  
the hardness of the wood and how wide the board  
is being passed under the cutterhead. Generally  
1
we recommend a maximum depth of 32". A  
series of light cuts will give a better end result  
than trying to take off too much material in a sin-  
gle pass, plus there is less strain on the motor.

Depth-of-Cut Indicator  
Reset Button  
The G8794 Planer comes equipped with a ther-  
mal overload protection switch which will trip if the  
motor builds up too high a level of heat. To reset  
the switch, turn the switch to the OFF position,  
wait a few seconds and then depress the reset  
button. See Figure 5. If the reset button does not  
stay depressed, wait longer before resetting to  
allow the machine to cool down.

SECTION 6: ADJUSTMENTS  
Knife Setting  
Extension Wings  
The G8794 Planer is equipped with a 2 blade cut-  
terhead. The blades are locked in position by a  
knife locking bar with seven bolts angled to put  
pressure on the assembly when they are tight-  
ened. A set of two springs under each blade  
pushes up to keep the blade portion exposed.  
The knife setting gauge is used to push down on  
the blade to set it to the proper height.  
Disconnect the power cord from the power  
source before adjusting or removing the  
knives.  
Your planer is equipped with front and rear exten-  
sion wings. Each wing folds up for machine  
mobility and down for machine operation. To  
check alignment, lay a straightedge across the  
bed and wings. See Figure 7.  
If adjustment is necessary, proceed as follows:  
1. Use the 10mm wrench and loosen the lock-  
ing nuts and set bolts underneath each  
extension wing.  
To remove the knives:  
2. Hold a straightedge across the bed and  
wing and turn the adjustment bolts so the  
end of the wing is flush with the straight-  
edge.  
1. Lower cutterhead to provide access to  
knives from the top.  
2. Remove chip deflector.  
3. Use the 8mm end of the wrench to loosen  
the bolts in the knife locking bar. Turn  
clockwise to loosen bolts and free the  
knife! (See Figure 8)  
4. Slide knife out of cutterhead. Use care  
when handling knives - they are sharp!  
5. Repeat steps three and four above to

To install and adjust the knives:  
turn the tightening bolts counterclockwise  
with the other hand. Tighten the seven bolts  
until they begin to contact the side of the  
groove. Then tighten further, starting with  
the bolts at the center and working toward  
the outer ones. Once they are tight enough  
to hold the knife in position, remove the  
gauge.  
1. Make sure the two springs in the knife  
groove are in position. If the knife locking  
bar was removed, make certain it is rein-  
serted with the bolts oriented as shown in  
5. Do a final tightening of each bolt. Recheck  
with the setting gauge to make certain the  
knife did not move. The knife tip should be  
just touching the top of the arc of the gauge  
as shown in Figure 10.  
6. Repeat Steps 1 through 5 above to set the  
second knife.  
7. Remove all tools and install chip deflector.

The cutterhead knives on the G8794 planer are  
extremely sharp. Merely brushing your finger  
along the edge can result in a severe cut. Take  
extreme caution when doing any adjustments  
involving the cutterhead knives. Wear thick  
gloves anytime it is necessary to manually  
rotate the cutterhead assembly.  
NOTICE  
Never run the planer with only one knife  
installed in the cutterhead. This will cause a  
severe imbalance condition at the high speed  
at which the cutterhead rotates. Always install  
both knives and make certain they are tightly  
secured. When resharpening, always have  
both knives sharpened as a set.

SECTION 7: OPERATIONS  
Test Run  
Planing Tips  
Once assembly is complete and adjustments are  
done to your satisfaction, you are ready to test  
the machine. Make certain you have removed  
any tools or gauges used in the adjustment or  
assembly process from the bed of the planer.  
Inspect your lumber for twist or cup and sur-  
face one face on a jointer if necessary.  
Scrape all glue off when planing laminated  
stock.  
Plug the planer in and make sure the power sup-  
ply is on at the main panel. With the locking key  
inserted, move the toggle switch to the ON posi-  
tion. Make sure that your finger is poised to flip  
the switch to the OFF position, just in case there’s  
a problem. The planer should run smoothly, with  
little or no vibration or rubbing noises. Strange or  
unnatural noises should be investigated and cor-  
rected before operating the machine further.  
Plane boards of equal thicknesses when  
planing multiples.  
Remove only 132'' to 116'' (.8mm to 1.6mm) of  
material on each pass. Remove less materi-  
al in each pass when planing wide or dense  
stock.  
Support lumber on both ends. Get assis-  
tance if planing long lumber, or use roller  
stands.  
If you cannot easily locate the source of an  
unusual noise or vibration, feel free to contact our  
service department for help.  
Measure workpiece with calipers to get exact  
results.  
Check surface of workpiece for any irregular-  
ities.  
Plane equal amounts on each side of the  
board to reduce the chance of warpage.  
Make sure the G8794 is unplugged or dis-  
connected from the power source and mov-  
ing parts have come to a complete stop  
before investigating any problems or per-  
forming any maintenance or adjustments.  
Serious personal injury may occur.  
Use entire width of planer to wear knives  
evenly.  
Surface wood with the grain. Never feed any  
end cut or end grained wood through the  
machine.

Wood Types  
Wood Characteristics  
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.  
The species of wood, as well as condition, will  
affect planing ability. The harder the wood, the  
more difficult it will be to plane. We’ve included  
below, 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.  
Commonly used hardwoods and their associated  
shear strengths are illustrated in Figure 11. High  
shear means difficult planing.  
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. Often, chipped  
grain can be avoided by taking shallow 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.

Fuzzy Grain - Usually caused by surfacing lum-  
ber with too high 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.

Similarly, common softwood shear strengths are  
displayed in Figure 12.  
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.

Snipe - 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.  
However, a small amount of snipe is inevitable.  
The best way to deal with snipe is by planing lum-  
ber longer than your intended work length and  
then cutting off the excess after planing is com-  
pleted.

Wavy Surface - Caused by poor knife height  
adjustment, wavy surface appears when one  
knife is taking deeper cuts than the rest of the  
knives. Recheck or reset knife height with the  
gauge.  
Pitch & Glue Build-up - Glue and resin build-up  
on the rollers and cutterhead will cause over-  
heating 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.  
Storing Power Cord  
The underside of the outfeed extension wing con-  
tains a convenient cord storage area. Just fold  
the wing up, and wrap the cord around the stor-  
age wires to keep the cord neatly stowed until the  
next use of this portable planer.  
Chip Marks or Indentations - Chip indentation  
or chip bruising is the result of wood chips not  
being thrown away from the cutterhead and out  
of the dust chute. Instead they are carried around  
the cutterhead, deposited on the planed surface  
and crushed by the outfeed roller. Chip indenta-  
tions can be caused by a number of reasons,  
some of which are:  
1. The type of lumber being planed. Certain  
species have a tendency to chip bruise.  
2. A high moisture content (over 15%) and/or  
surface moisture. Typically found in air-  
dried stock where the surface is dry but the  
inside needs a longer time to season.  
Figure 13. Convenient cord storage.  
3. Dull knives.  
4. Too much material being removed in one  
pass.  
5. Improper knife cutting angle.  
Possible Solutions:  
1. Lumber must be completely dry, preferably  
kiln-dried (KD). Air-dried (AD) lumber must  
be seasoned properly and have no surface  
moisture. Do not surface partially-air-dried  
(PAD) lumber.  
2. Make sure planer knives are sharp.  
3. Remove less material per pass.  
4. Use a smaller cutting angle or a double  
bevel grind (consult a reputable knife  
grinder).

SECTION 8: MAINTENANCE  
General  
Knife Sharpening  
Regular periodic maintenance on your Model  
G8794 Planer will ensure its optimum perfor-  
mance. Make a habit of inspecting your planer  
each time you use it. Check for the following con-  
ditions and repair or replace when necessary:  
• Loose mounting bolts, extension wings, or  
handles, or excessive play in the depth-of-  
cut adjustment.  
Knife sharpness is one of the most important fac-  
tors in getting good results with the planer. Knives  
can be made to last a long time if care is taken in  
checking the condition of the wood which is put  
into the machine. The biggest problem will come  
from wood with nails or other metal embedded.  
This will nick or chip the knives and can require a  
complete regrinding. Another wear factor is sand,  
grit, or other dirt on the surface of the wood which  
the knives have to cut through. Simply laying a  
board on a concrete floor can embed enough  
abrasive material to severely damage the knives.  
At the speed the cutterhead is rotating, these  
types of surface contamination can have a very  
abrasive effect.  
• Worn switch.  
• Worn or damaged cords or plugs.  
• Dull or damaged cutterhead knives.  
• Any condition that could hamper the safe  
operation of the machine.  
This planer has knives with a grind angle of 40˚  
which is a configuration which should suit most  
general planing needs. The optimal grind or bevel  
angle is a compromise between effective cutting  
(the smaller the angle the better the cutting  
action) and edge life where the larger the angle  
the more the edge is supported, thus the longer it  
will last.  
The cutterhead knives on the G8794 planer are  
extremely sharp. Merely brushing your finger  
along the edge can result in a severe cut. Take  
extreme caution when doing any of the adjust-  
ments involving the cutterhead knives. Wear  
thick gloves anytime it is necessary to manu-  
ally rotate the cutterhead assembly.  
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. It is a pro-  
cedure which requires some care and precision,  
otherwise a set of blades can be easily ruined.  
Knives should always be ground as a set so they  
can be properly matched. Unequal material  
removal can result in an unbalanced cutterhead  
which can affect not only planing surface quality  
but ultimately the life of the cutterhead bearings.  
NOTICE  
Never run the planer with only one knife  
installed in the cutterhead. This will cause a  
severe imbalance condition at the high speed  
at which the cutterhead rotates. Always install  
both knives and make certain they are tightly  
secured. When resharpening, always have  
both knives sharpened as a set.  
Please refer to Section 6 Adjustments - Knife  
Setting for complete detail on the removal and  
reinstallation of planer knives.

Motor  
V-Belt  
Keep the motor as clean as possible. Prevent any  
water, oil or wood chips from penetrating inside  
the motor. Be sure to clean the machine after  
every use.  
The cutterhead is driven by a flat rubber V-belt  
located on the right side of the motor and cutter-  
head assembly (when facing the front of the  
machine). The belt is a durable long life belt, how-  
ever eventually it may require replacement:  
The bearings inside the motor are also shielded  
and lubricated for the life of the bearing and  
require no routine maintenance.  
1. Remove the depth-of-cut handle and the  
four Allen® head screws on the top cover.  
Pull the cover off and the sides are then  
free to be removed.  
This motor is equipped with long life carbon  
brushes. However, brush life expectancy is  
affected by motor loading. Planing very wide,  
dense boards or cutting too deep will reduce  
brush life. Check brushes after every ten to fifteen  
hours of operation. See Figure 14. When the  
2. Remove the Belt Guard Cover. This piece  
just snaps into two grooves. Squeeze the  
top of the cover slightly and pull up to  
remove. See Figure 15.  
3. ''Roll off'' the old belt toward the side of the  
elevation screw.  
4. Loop the new belt so that it completely sur-  
rounds the motor pulley but with only half  
the "vees" engaged. Start the lower portion  
on the underside of the cutterhead pulley  
and slowly rotate the motor pulley with your  
free hand.  
5. By pushing on the edge of the belt and  
slowly turning the pulleys by hand, you can  
force the belt over until all the "vees" of the  
belt are in alignment with the "vees" on the  
pulley.  
6. Replace the belt guard, sides, cover and  
handle.  
Figure 14. Brush holder location.  
brushes are worn down to 14'' (6mm), it is time for  
replacement. When checking brushes, be sure to  
replace each brush in the same position and the  
same location that it came from. When replacing  
old brushes, be sure to replace both brushes at  
the same time.

roller.  
6. Replace the sides, cover and depth-of-cut  
handle.  
The feed rollers rotate in bushing blocks that are  
spring-loaded. The feed rollers ride up on the  
board so roller pressure is maintained. If chips or  
sawdust build up between the bracket and bush-  
ing block, the amount of roller vertical travel will  
be reduced. See Figure 16.  
Lubrication  
There are two primary points requiring periodic  
lubrication; the head elevation screws and the  
feed roller chain drive. Access for lubrication  
requires removing the cover and sides of the  
machine first. Remove the depth-of-cut handle  
and the four Allen® head screws on the top cover.  
Pull the cover off and the sides are then free to be  
removed. See Figure 17.  
The elevation screws on each side of the  
machine should be coated with a light grease to  
lubricate the threads. The chain drive can be  
lubricated with a spray oil. Saturate each chain  
link, then wipe off the excess so that sawdust will  
not be attracted.  
Remove trapped sawdust from between  
the bushing block and the bracket  
Figure 16. Location of potential trapped sawdust.  
Periodically check and clean chips and sawdust  
from between the bushing blocks and brackets.  
Remove the side covers from the Planer by  
removing the depth-of-cut handle on top, and  
then remove the four Allen® head screws holding  
the cover. Lift the top cover off, then remove the  
sides. This provides easy access to depress the  
rollers so that chips and sawdust can be easily  
removed:  
Replace the sides, cover and handle when com-  
plete.  
Elevation Screw  
1. Place a 3-4'' high block of wood between  
one of the feed rollers and the planer bed.  
Ensure that the block of wood is not under  
the cutterhead.  
2. Lower the cutterhead assembly down just  
enough so that the roller is pushed up  
against the spring and pressure is off of the  
two brackets.  
Figure 17. Lubrication of chain and screw.  
3. Remove any trapped material from  
between the roller assembly and bracket.  
4. Raise the cutterhead assembly and remove  
the block of wood.
