Clean up
Site Considerations
The unpainted surfaces are coated with a waxy
oil to protect it from corrosion during shipment.
Remove this protective coating with a solvent
cleaner or citrus-based degreaser. 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 G1017 is designed to be portable.
There are handles on both sides of the planer to
aid in lifting and moving. Before moving the plan-
er, fold the depth control handle down, the exten-
sion wings up and ensure that the power cord is
disconnected.
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 poten-
tial ignition sources when dealing with sol-
vents. Use care when disposing of waste
rags and towels to be sure they do not cre-
ate fire or environmental 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
flammable. A risk of explosion and burning
exists if these products are used. Serious
personal injury may occur.
The cutterhead knives on the G1017 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 adjustments involving the cutterhead
knives. Wear thick gloves anytime it is nec-
essary to manually rotate the cutterhead
assembly.

SECTION 4: ASSEMBLY
Wooden Base
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:
The wooden base yields greater stability and
enables the planer to be fastened to a sturdy
bench or floor when planing long stock. To con-
struct the wooden base pieces:
1. Mill two pieces of wood 17'' (L) x 2'' (W) x 2''
(H). Do not use planer for constructing base
pieces until it is checked out and adjust-
ments have been made as required.
1. Remove the two socket head cap screws at
the rear of the planer.
2. Set chip deflector in place and replace the
two socket head cap screws. See Figure 2.
2. Layout the two planer mounting hole loca-
tions on each piece.
3. Predrill mounting holes and mount the plan-
er using four 5⁄16'' lag bolts and washers pro-
vided. See Figure 3.
Alternatively, the planer can be directly mounted
to a bench or table top, or to a Shop Fox® Deluxe
Tool Table utilizing these same mounting holes,
using the appropriate fasteners.
Figure 2. Chip deflector mounting screws.
Handle Assembly
Figure 3. Mounting planer to wooden base.
Attach the handle assembly to the shaft protrud-
ing out of the top of the planer. Align the handle
with the notch, and tighten the M6-1 x 10mm cap
screw. Do not over tighten.

SECTION 5: CONTROLS
On-Off Switch
Depth Of Cut
The on-off switch is located on the front of the
planer. See Figure 4. 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.
The planing depth is controlled by the crank han-
dle on top of the planer. To extend the handle up
for operation, pull out on the handle while folding
it up. Turning the handle clockwise raises the cut-
terhead and counter-clockwise lowers the cutter-
head. See Figure 5. Depth of cut is read directly
from the inch/millimeter scale located on the top,
right side of the planer. The minimum reading is
1⁄16'' (1 mm). One complete turn of the handle rais-

ensure consistency from side to side.
Without turning the set bolts, tighten the
lock nuts.
Your planer is equipped with front and rear exten-
sion wings. Each wing folds up for machine mobil-
ity and down for machine operation. To check
alignment, lay a straightedge across the bed and
wings. See Figure 6.
4. To adjust the second wing, repeat steps
one through three above.
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.
Feed Rollers
2. Hold a straightedge across the bed and
wing and turn the setscrews so the end of
the wing moves back into the same plane
as the planer bed.
The infeed and outfeed rollers are made of high
quality rubber and provide effective gripping pres-
sure during operation. The delivery speed is 26
FPM (8 MPM).The infeed and outfeed roller pres-
sure was pre-set at the factory and requires no
adjustment.
The cutterhead knives on the G1017 planer
are extremely sharp. Merely brushing your

2. Raise the cutterhead so that the wood
gauge fits between the edge of the knife in
the cutterhead and the planer bed. Place
the gauge to one end of the cutterhead.
Adjust the crank handle so the knife edge
just makes contact with the gauge at its
lowest point. See Figure 8.
Parallelism
Before leaving the factory, the planer cutterhead
was set parallel to the planer bed for even cutting.
However, periodic inspections should be done to
ensure accuracy, especially if the planer is jostled
during transport. To check parallelism between
the cutterhead and bed, switch planer off, wait for
moving parts to stop and proceed as follows:
3. Shift the hardwood gauge to the other end
of the cutterhead without changing the
position of the cutterhead. If the block
begins to bind against the cutterhead as
you move to the opposite end, lower the
table and go back to step 2, starting at this
end instead.
1. Construct a hardwood gauge as shown in
Figure 7.
4. Check to see if there is any gap between
the knife edge and the block at the other
end. The knife edge should just touch the
block all the way along the length of the
knife.

Scrape all glue off when planing laminated
stock.
Turn on the power supply at the main panel.
Press the ON button. Make sure that your finger
is poised on the OFF button, 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 1⁄32'' to 1⁄16'' (.8mm to 1.6mm) of
material on each pass. Remove less materi-
al in each pass when planing wide or dense
stock.
If you cannot easily locate the source of an
unusual noise or vibration, feel free to contact our
service department for help.

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 12. 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 13.
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 one or both of the bed
rollers are set too low. However, small amount of
snipe is inevitable. The best way to deal with
snipe is by planing lumber longer than your
intended work length and then cutting off the
excess after planing is completed.

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 to ±.001''.

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.
Notes
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 indentations
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.
3. An inefficient dust collection system without
enough suction capacity or an incorrectly
engineered and assembled system.
4. Dull knives.
5. Too much material being removed in one
pass.
6. 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 sur-
face moisture. Do not surface partially-air-
dried (PAD) lumber.
2. Make sure planer knives are sharp.
3. Use an adequate dust collection system,
one that uses relatively few turns and is as
air tight as possible.
4. Remove less material per pass.
5. 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
G1017 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.
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. At the speed the
cutterhead is rotating, these types of surface con-
tamination can have a very abrasive effect.
Routinely check the condition of the follow-
ing items and repair or replace as neces-
sary:
• Loose mounting bolts, extension
wings, or handles, or excessive play
in the depth of cut adjustment.
• Worn switch.
This planer has knives with a grind angle of 50˚
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.
• Worn or damaged cords or plugs.
• Dull or damaged cutterhead knives.
• Any condition that could hamper the
safe operation of the machine.
Serious personal injury may occur.
For the best results it is best to have planer knives
sharpened by a professional sharpening service
which has the grinding and measurement equip-
ment to assure that the knife cutting geometry is
maintained at optimum levels. It is a procedure
which requires some care and precision, other-
wise 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 ulti-
mately the life of the cutterhead bearings.
Lubrication
Since all bearings are shielded and permanently
lubricated, simply leave them alone until they
need to be replaced. Do not lubricate them.
As for other items on this machine, such as the
depth adjusting screw-threads, an occasional
“shot” of light oil is all that is necessary.
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. Do not use compressed air to remove
saw dust. Dust may be forced into normally pro-
tected parts which may cause damage to the
machine.
The cutterhead is driven by a rubber V-belt locat-
ed on the left side of the motor and cutterhead
assembly. The feed rollers are driven by a chain
on the right side of the motor and cutterhead
assembly. To inspect or remove the V-belt:
1. Lower the cutterhead assembly and leave a
gap along the front edge of 11⁄2'' to the table.
The bearings inside the motor are also shielded
and lubricated for the life of the bearing and
require no routine maintenance.
2. Remove the Belt Guard Cover.
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.
Figure 14. Brush holder location.
This motor is equipped with long life carbon
brushes. However, brush life expectancy is affect-
ed 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 brushes are
1
worn down to ⁄4'' (6mm), it is time for replace-
ment. 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.

Routinely check and clean chips and sawdust
from between the bushing blocks and brackets.To
depress the rollers so that chips and sawdust can
be easily removed:
Feed Rollers
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 15.
1. Place a 5'' block of wood between one of
the feed rollers and the planer bed. Ensure
that the block of wood is not under the cut-
terhead.
2. Lower the cutterhead assembly down just
enough so that the roller pressure is off of
the two brackets.
3. Remove any trapped material from
between the roller assembly and bracket.
4. Raise the cutterhead assembly and remove
the block of wood.
Repeat Steps 1 through 4 above to clean chips
and sawdust from the second feed roller.
Remove trapped sawdust from between
the bushing block and the bracket
