Additional Safety Instructions For Planers
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 personal injury, damage to equipment
or poor work results.
Like all power tools, there is danger associated with the Model G1021Z 15" Planer.Use
the tool with respect and caution to lessen
the possibility of mechanical damage or
operator injury. If normal safety precautions are overlooked or ignored. Serious
personal injury may occur.
1. Ensure that the machine sits firmly on the
floor before use. Any “wobbles” must be
corrected by shimming or blocking before
operation.
2. This machine is not designed to process
any other material except wood.
3. Never position fingers or thumbs near the
infeed roller.
4. Long stock should always be fully supported by some type of support fixture.
5. Do not operate planer with dull or damaged
knives.
6. Ensure that the planer is properly adjusted
before using.
7. Do not remove excessive amounts of
wood in a single pass.
8. Inspect your stock before planing. Reject
stock with defects and foreign material.
9. Do not attempt to remove jams until power
is disconnected and all moving parts have
come to a complete stop.
10. Provide adequate infeed and outfeed
space for operating the planer.
11. Do not plane wood less than 12" long and
1
⁄4" thick.
12. Do not plane lumber with loose knots or
knots that may become loose during
planing.
Operation of this equipment has the potential to propel debris into the air which can
cause eye injury. Always wear safety glasses or goggles when operating equipment.
Everyday glasses or reading glasses only
have impact resistant lenses, they are not
safety glasses. Be certain the safety glasses you wear meet the appropriate standards of the American National Standards
Institute (ANSI).

G1021Z 15" Planer -7-
220V Operation
SECTION 2: CIRCUIT REQUIREMENTS
The G1021Z Planer motor is wired to operate at
220V only. A cordset without a 220V plug is
included with the Model G1021Z. Plugs and
receptacles can be purchased at your local hardware store or home center. Contact your local
electrical contractor if uncertain about connecting
to a 220V circuit.
When operating at 220V, we recommend using a
NEMA-style 6-15 plug and outlet as depicted in
Figure 1. You may also “hard-wire” the planer
directly to your panel, provided you place a disconnect switch near the machine.Check the electrical codes in your area for specifics on wiring
requirements.
Under normal load, the Model G1021Z draws
about 12 amps.We recommend a 15-amp circuit
or a 20-amp slow-blow fuse. A circuit rated any
higher will not adequately protect the motor.
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.
Fusing
We do not recommend the use of extension cords
on 220V equipment. It is much better to arrange
the placement of your equipment and the
installed wiring to eliminate the need for extension cords. Should it be necessary to use an
extension make sure the cord is rated Hard
Service (grade S) or better. Refer to the chart in
Section 1: 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.
Extension Cords
Grounding
This equipment must be grounded. Please
ensure that this machine is continuously
grounded from the motor to the machine frame
and then to a known ground. Verify that any
existing electrical outlet and circuit you intend
to plug into is actually grounded. 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 personal injury may
occur.
Figure 1. NEMA 6-15 220V/15A connector.
In the event of an electrical short, grounding
reduces the risk of electric shock by providing a
path of least resistance to disperse electric current.This tool is equipped with a power cord having an equipment-grounding conductor.The outlet must be properly installed and grounded in
accordance with all local codes and ordinances.

Clean Up
The unpainted surfaces are coated with a waxy
oil to protect them from corrosion during shipment. Remove this protective coating with a solvent cleaner or citrus-based degreaser. Avoid
chlorine-based solvents as they may damage
painted surfaces should they come in contact.
Always follow the usage instructions on the product you choose for clean up.
Follow the safety rules listed below when
working with solvents.
1. Read and follow all directions and
warnings on the solvent label.
2. Work only in a well ventilated area.
3. Do not work near any type of open
flame (e.g., pilot lights, kerosene
heaters, and so on).
4. DO NOT smoke while working with
flammable material.
5. Paper towels from the cleaning pr ocess
are extremely combustible. Dispose of
waste towels so they do not create a
fire hazard.
Site Considerations
FLOOR LOAD
Your G1021Z Planer represents a large weight
load in a small footprint. Most commercial floors
are suitable for the Model G1021Z. Some residential floors may require additional support to
accommodate both machine and operator.
WORKING CLEARANCES
Working clearances can be thought of as the distances between machines and obstacles that
allow safe operation of every machine without
limitation. Consider existing and anticipated
machine needs, size of material to be processed
through each machine, and space for auxiliary
stands and/or work tables. Also consider the relative position of each machine to one another for
efficient material handling. Be sure to allow yourself sufficient room to safely run your machines in
any foreseeable operation.
LIGHTING AND OUTLETS
Lighting should be bright enough to eliminate
shadow and prevent eye strain.Electrical circuits
should be dedicated or large enough to handle
combined motor amp loads. Outlets should be
located near each machine so power or extension cords are not obstructing high-traffic areas.
Be sure to observe local electrical codes for proper installation of new lighting, outlets, or circuits.
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 environmental hazards. Keep
children and animals safely away when
cleaning and assembling this machine.
Make your shop “child safe”. Ensure that
your workplace is inaccessible to youngsters by closing and locking all entrances
when you are away. Never allow visitors in
your shop when assembling, adjusting or
operating equipment.

Lifting Handles
This planer is heavy and awkward to move.
We recommend that you use the proper
equipment to put the planer into position in
your shop or on a mobile base. Lifting without proper equipment or ample assistance
could result in serious injury.
Figure 2. Location of lifting handles.
SECTION 4: ASSEMBLY
Overview
The G1021Z Planer requires very little assembly
when you receive it. There a just a few easy
assembly steps to get the machine ready for your
shop. The machine should be properly adjusted
from the factory, however should you desire to
check the various settings, the following section
will detail the proper adjustment procedures.
This planer unit is very heavy, approximately 480
lbs.There are lifting handles which slide out of the
base of the planer head (Figure 2) which can be
used to move the unit.These can be used as lifting points using an overhead lift, block and tackle or a forklift, or if you have three other friends
who are each willing to grab a handle!
Handwheel
The handwheel is used to raise and lower the
planer table.
TO MOUNT THE HANDWHEEL:
1. The handwheel shaft is at the front right
corner of the planer. Insert the key into the
keyway on the shaft, then line up the notch
on the handwheel bore with the key. Slide
the handwheel onto the shaft.
2. Slide the direction scale over the keyed
shaft so it sits on the center face of the
handwheel. See Figure 3.
3. Secure the handwheel with the 10mm -

SECTION 5: ADJUSTMENTS
Overview
Once assembly has been completed, your
G1021Z 15" Planer requires just a few adjustments to ready it for use in your shop.
Many adjustments have already been made at
the factory, yet we recommend you familiarize
yourself with all of the following procedures to
gain a better understanding of the Planer’s construction and operation.
General control and adjustment locations are
shown in Figure 9:
A. The switch is thermally protected and mag-
netically controlled and features push buttons to turn the planer on and off.
B. The handwheel raises and lowers the table
and controls the depth of cut. Turning the
handwheel clockwise raises the table and
counter-clockwise lowers the table.
C. The bed rollers ease stock movement
through the planer and are adjustable.
D. The three position feed rate change knob
shifts planer feed speed from neutral to 16
and 20 feet per minute.
E. The table lock knob secures the table in a
fixed position.
F. Extra large ball bearing return rollers
G. Removable belt guard.

Gauge Block
Before attempting any table adjustments, you will
need to construct a gauge block. See Figure 10.
A larger gauge block diagram is also included at
the end of the manual for your convenience.
Precision adjustments later on require accuracy
when milling the gauge block. Do not use common 2x4 material. Use maple or similar type of
hardwood.
Using a magnetic dial indicator is a good alternative to constructing a gauge block. Use the dial
indicator whenever the instructions call for use of
the gauge block and/or feeler gauge.Refer to the
current Grizzly catalog for dial indicators.
Table Adjustment
To plane stock perfectly square, it is important
that the table is parallel to the cutterhead.
TO CHECK TABLE PARALLELISM:
1. Place the gauge block on the table under
one end of the cutterhead.
2. Tur n the handwheel to raise the table until
the block barely touches the cutterhead
body. The block should not be touching
the knives. See Figure 11.
3. Slide the block toward the opposite side of
the cutterhead. Use a feeler gauge to measure the width of the gap, if any, between
the top of the block and the bottom of the
cutterhead. If there is a gap, make a note,
reading the distance from the feeler gauge.
4. 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 cutterhead.
Figure 10. Guide block specifications.
DO NOT make adjustments while the planer
is running. Ensure that the switch is off,
power is disconnected and moving parts
have stopped before making adjustments.
Failure to comply could result in serious
injury or electrical shock hazard.
Figure 11. Guide block indicates parallelism.
If the gap difference from one side to the other is
equal to or less than 0.004", no further adjustment is necessary.
Page 16
-16- G1021Z 15" Planer
Figure 12. Cap screws for column adjustment.
If the gap difference from one side to the other is
greater than 0.004", but less than 0.016", go to
step 5.
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.
To adjust for gap differences of less than 0.016":
5. Determine which side of the table must be
raised to correct the gap.
6. Locate the two cap screws in the table casting for each of the columns.See Figure 12.
Loosen both sets of cap screws for each
column on the side you wish to adjust.
7. Push down or pull up the table in the
desired direction. Hold the table in position
and retighten the cap screws.
8. Recheck the table to cutterhead parallelism
again. Repeat steps 1 through 7 until the
deviation is less than 0.004".

Loosen these cap
screws to micro adjust
the table height
Notes
Planer knives are dangerously sharp. Use
extreme caution when inspecting,removing,
sharpening, or replacing knives into the cutterhead. Substantial risk of injury!
Page 17
G1021Z 15" Planer -17-
Figure 14. Placing springs into knife slots.
Figure 15. Cover Removed, Jig on cutterhead
The knives of your planer must be periodically
adjusted and will ultimately need to be removed
for sharpening.Adjustments should be as precise
as possible with tolerances within .002"-.003" to
prolong the sharpness of the knife edges.
Improperly adjusted knives can cause an imbalance condition in the cutterhead and shorten
bearing life, as well as produce substandard
planing results.
TO INSPECT THE KNIVES:
1. UNPLUG THE PLANER!
2. Remove the dust port and upper cover and
cutterhead guard to expose the top of the
cutterhead. See Figure 15.
Knife Inspection
The knives are set at the factory using jack
screws before shipping.Springs are also included
with your machine, installed beneath the knives.
These may be used instead of the jack screws
depending on your preference. Refer to Figure
13 for placement of the jack screws or springs.

If you decide you prefer to use the spring adjustment method, you need to remove each knife,
remove the jack screws, leave the two springs
under each knife, and replace the knife.
Loosen the gib bolts until the knife is loose in the
slot. The gib bolts turn clockwise to loosen and
counterclockwise to tighten (when facing the
head of the bolt).Carefully remove the knife.Back
the jack screws out completely from the threaded
hole and remove.If the springs have become dislodged in the removal process, be sure to place 1
spring in each of the two holes in bottom of the
knife slot.The springs do not
go into the threaded
hole where the jack screws were installed. See
Figure 14.
When using jack screws, it is not necessary to
install the springs. However it will not affect the
adjustment if both the springs and jack screws
are in place together.

Figure 16. Proper knife setting jig placement.
3. Remove the belt guard. Carefully turn the
cutterhead (using the pulley) until the first
knife is top dead center.
4. Using the knife setting gauge, check the
knife height. The jig should sit solidly with
both feet on the cutterhead.See Figure 16.
If the knife is adjusted properly, the contact
point at the center of each adjuster should
just touch the tip of the knife. If the knife
does not make contact, or if the knife causes the adjuster’s legs to not seat on the cutterhead, the knives need to be adjusted. It
may be helpful to mark the side of the knife
with an ink marker to indicate whether it is
high or low .This will make the actual adjustment process easier.
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 cutterhead. Proceed to the appropriate section following depending upon whether you are using the
jack screws or the springs.
Knife Sharpening
Knife sharpness is one of the most important factors 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 contamination can have a very abrasive effect.
This planer has knives with a grind angle of 35˚
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.
For the best results it is best to hav e planer kniv es
sharpened by a professional sharpening service
which has the grinding and measurement equipment to assure that the knife cutting geometry is
maintained at optimum levels. It is a procedure
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.
Please refer to Section 6 Adjustments - Knife
Setting for complete detail on the removal and
reinstallation of planer knives.

Knife Setting
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 performance and possible operator injury.
The knives are locked into the cutterhead with
wedge-type gibs and gib bolts.Jack screws under
the knives allow fine tuning to help in the setting
process.
To set the knives:
1. UNPLUG THE PLANER!
2. Remove the upper cover to expose the cut-
terhead.
3. Loosen the gib bolts until the knife is loose
in the slot. The gib bolts tur n clockwise to
loosen and counterclockwise to tighten
(when facing the head of the bolt). See
Figure 17.

SCREWS
Figure 18. Tightening knives in cutterhead.
5. Adjust the screws below each end of the
knife until both feet of the gauge rest evenly on the cutterhead and the knife is just
touching the bottom of the middle foot of
the gauge.The gauge will set the knives at
a uniform protrusion of approximately .070"
above the cutterhead. The knife height
should vary no more than .002"-.003"
across the length of the cutterhead.
6. Maintain a constant pressure on the gauge
while re-tightening the gib bolts.
7. Repeat the same procedure on the remaining knives. As mentioned before, the standard knife setting gauge is satisfactory for
reasonably accurate knife setting tasks.
4. Place the knife setting jig over the knife on
the cutterhead as shown in Figure 18.The
feet should be securely planted on the cutterhead. Make sure the gauge extension
rod is parallel to the cutterhead to maintain
accuracy.
Planer knives are dangerously sharp. Use
extreme caution when inspecting, removing, sharpening, or replacing knives into the
cutterhead. Substantial risk of injury!

Figure 22. Chip breaker height adjustment.
6. If an adjustment is necessary, loosen the
locknuts and turn the setscrews. See
Figure 22. Stop turning when the bottom of
the chip breaker just touches the gauge
block.
7. Re-tighten both locknuts
8. Replace the exhaust hood.
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 cutterhead. The chip breaker also deflects and expels
the woodchips away from the surface of the
board and out of the planer.
TO ADJUST THE CHIPBREAKER:
1. Disconnect the machine from the power
source, remove the dust hood and lower
the table.
2. Ensure that the knives are properly adjusted.
3. Place the gauge block on the table directly
under the cutterhead. Using a one millimeter (0.040") 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 manually to be sure the knife is at bottom dead
center.
4. Lock the table by tightening the table lock
knobs.
5. Remove the feeler gauge and slide the
gauge block under the chip breaker. See
Figure 21. 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.

DO NOT make adjustments while the planer
is running. Ensure that the switch is off,
power is disconnected and moving parts
have stopped before making adjustments.
Failure to ensure that power is disconnected could result in serious injury or electrical shock hazard.

Feed Roller Height
The infeed and outfeed rollers propel the lumber
through the planer.The rollers also press the lumber flat against the planer table.
Set the infeed and outfeed rollers 0.040" below
the knife edge at bottom dead center.
TO CHECK ROLLER HEIGHT:
1. Disconnect the machine from the power
source.
2. Lower the table so the gauge block will fit
under one side of the infeed roller.
3. Raise the table until the gauge block barely
touches the infeed roller. See Figure 23.
Do not change position of the table.
4. Slide the gauge block over so it is under the
edge of one of the knives. Turn the cutterhead until one of the knives is at bottom
dead center over the gauge block.
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 roller. Repeat all steps for the outfeed
roller.
Feeler gauge measurement should equal 0.040".
TO ADJUST ROLLER HEIGHT:
1. Remove the drive chain cov er 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. Belt side
adjustments are already accessible.
2. Loosen the roller adjustment check nuts
and turn the roller height setscrews to
change the height of the roller as needed.
See Figure 24.
3. Check roller height according to the above
instructions. Continue tur ning the setscrew
until the roller is properly adjusted.
4. When the roller is set in the correct position, re-tighten the check nuts you loosened
in Step 2 above.
5. Check your settings one last time and
repeat steps 1-4 if necessary.

4. Remove the springs that are in the holes
left by the setscrews.See Figure 26.
5. Check for any dirt or grit. 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.
7. Screw the light pressure setscrew until it is
approximately
1
⁄4" above the head casting.
The feed chain applies additional tension to
the right side of the outfeed roller, so the
pressure added by the setscrew need not
be as high.
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.
Experiment with the best pressure settings for
your work situations. Some rough cut lumber will
feed through fine with relatively few problems,
while other lumber will have more difficulty.
Adjusting roller pressure does not affect height.
TO ADJUST ROLLER PRESSURE:
1. Disconnect the machine from the power
source.
2. Ensure that knives and feed rollers are set
correctly.
3. Unscrew the four large pressure setscrews
on top of the planer body. See Figure 25.

Bed Rollers
Figure 27. Inspecting bed roller height.
4. Use a wrench to turn the eccentric shafts
which adjust roller height. Stop turning
when the table rollers are at the proper
height.
5. Once your roller heights are correct, retighten all the setscrews.
6. Check the height of the table rollers.Repeat
steps 1-5 until the bed rollers are properly
set. Spin the bed rollers to ensure free
movement.
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 planing. When planing rough stock, set the rollers
slightly high to keep the lumber from dragging
along the bed. However, snipe may be unavoidable. Smooth lumber should be planed with the
rollers set just above the plane of the table. This
will minimize snipe.
TO ADJUST THE BED ROLLERS:
1. Ensure that power is disconnected and lay
a high quality straightedge across both
table rollers. Use a tr y square to keep the
straightedge perpendicular to the table.
2. Use a feeler gauge to measure the clearance between the bottom of the straight
edge and the table. Ideal clearance is
between 0.002" and 0.005". Measure in
several places.This measurement must be
consistent across the entire table. See
Figure 27.
Figure 28. Adjusting bed roller height.
3. Loosen the setscrews on both sides of
each bed roller. See Figure 28.

Chip Deflector
The chip deflector keeps chips from falling onto
the outfeed roller. It is the orange plastic plate
located under the top cover.
The beveled edge of the chip deflector should be
about
1
⁄8" - 1⁄4" from the knife edge.Carefully rotate
the cutterhead to gauge the distance between the
chip deflector and the knives.Adjust if necessary.
However, if the chip deflector is set too close to
the knives, the rotating cutterhead may pull it in
and destroy it.
TO ADJUST THE CHIP DEFLECTOR:
1. Disconnect the machine from the power
source and remove the planer’s upper
cover.
2. Loosen the three deflector mounting bolts.
See Figure 29. Make sure the beveled
edge of the deflector faces the cutterhead.
3. Move the deflector until its edge is approximately
1
⁄8" - 1⁄4" from the tip of the cutting
knives. Push down on the deflector with a
wooden stick to check if it will touch the
knives. Cautiously rotate the cutterhead to
ensure clearance. Do Not touch the knives
- severe cuts may result.
4. Re-tighten the chip deflector mounting bolts
and re-mount the upper cover to the planer.

The Model G1021Z Planer provides an anti-kickback safety feature. The anti-kickback fingers
hang from a rod suspended across the front of
the cutterhead casting. The anti-kickback fingers
should be inspected regularly. Check the fingers
to ensure that they swing freely and easily. See
Figure 30.
Figure 30. Anti-kickback assembly.
The belt and pulley assembly are on the left side
of the planer. The belts transfer power from the
motor to the cutterhead and then through the
gearbox to the feed rollers .Remove the belt cover
by unscrewing the two lock knobs holding the
cover in place.
TO INSPECT/ADJUST THE PULLEYS:
Place a metal ruler or other straightedge across
the pulleys to check alignment. The pulleys are
aligned if the ruler crosses them evenly. See
Figure 31.
If the pulleys are out of alignment:
1. Loosen the bolts that hold the motor to the
motor mount bracket.
2. Adjust the position of the motor until the
pulleys are in line.
3. Re-tighten all bolts.
Figure 31. Checking pulley alignment.
DO NOT apply oil or other lubricants to the
anti-kickback fingers. Oil or grease will
attract dust and restrict free movement of
the fingers, which could result in damage to
your workpiece,the planer,or possibly serious injury to the operator or others in the
workplace. Call our Customer Service number if the anti-kickback fingers do not move
freely when setting up your planer. DO NOT
attempt to use the planer if the anti-kickback fingers are not operating properly.

TO CHECK BELT TENSION:
Squeeze the V-Belts at their midpoints with moderate 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 adjust belt tension:
1. Remove the belt guard using the two
threaded knobs. Remove the panel at the
back of the machine stand to gain access
to the motor assembly.
2. The motor pivots on a platform which is
suspended at one end by a threaded
adjustment bolt. Adjust the two locknuts up
or down the shaft until the desired belt
deflection is achieved.See Figure 32.
3. Tighten the bolts against the pivot plate to
lock the motor adjustment into place.
4. Check belt tension again. Repeat steps 2-3
as necessary.
Figure 32. Adjusting belt tension.
The gearbox is located just behind the handwheel
on the right side of the planer.The gearbox transfers 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.
TO INSPECT THE GEARBOX:
1. Loosen the socket head cap screw on the
gearbox cover.Gently pull the cover off the
roll pins that hold it in place.
2. Check the bolts holding the sprockets in
place. Inspect the drive chains to ensure
that the retaining clips are in place.Replace
the clips if necessary. See Figure 33.
Figure 33. Location of sprocket bolts.
Move these nuts to
adjust belt tension.
DO NOT make adjustments while the planer
is running. Ensure that the switch is off,
power is disconnected and moving parts
have stopped before making adjustments.
Failure to comply could result in serious
injury.

The thickness scale, located below the handwheel,
can be adjusted for accuracy. However, material
must be run through the machine to adjust the
thickness scale.Make certain you ha ve f ollo wed the
directions in the Operations Section for Test
Running before attempting to make these adjustments.
TO ADJUST THE SCALE:
1. Adjust the table height to the approximate
thickness of your test lumber. Measure the
lumber with calipers to determine its exact
thickness.
2. Move the table to
1
/16" under the thickness of
your lumber and feed y our 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.

planer on long stock, use the stock return
rollers on the top of the machine to move the
material back to the infeed side of the
machine.
9. Avoid planing wood with a high water content.
Wood with more than 20% moisture content or
wood exposed to rain or sno w, will plane poorly and cause excessive w ear to the kniv es and
motor. Excess moisture can also hasten rust
and corrosion.
10.Read as much as possible about planing procedures.Alternative publications present more
wood specific planing requirements. They will
often share tips on safety and more efficient
ways to operate your planer.
1. Inspect lumber for defects, warping, cupping,
twisting, and for 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 wood.
2. Use the full width of the planer. Alternate
between the left, the right and the middle
when feeding lumber into the planer. Your
knives will remain sharp much longer.
3. Scrape all glue off of joined boards before
planing.
4. Plane ONLY natural wood fiber.No wood composites, laminates, particle board, plywoods or
plastics should be run through the planer.
5. Surface wood with the grain. NEVER feed
end-cut or end-grained lumber into your
planer.
6. Do not use boards with knots, splits, crossgrain or other obvious blemishes or defects.
They can damage the machine and pose the
possibility of operator injury.
7. Keep your work area clear.
8. When making multiple passes through the
Before attempting to adjust table height, loosen
the two black knobs on the left side of the table.
After table height is adjusted and the table height
is set, tighten the two black knobs back down
again. See Figure 35.

The Model G1021Z 15" Planer is a powerful
woodworking machine, designed and constructed for professional-quality applications. Because of its powerful motor and
razor-sharp knives, the Model G1021Z is
inherently dangerous and should be operated with considerable caution and respect.
Failure to do so could result in damage to
the machine, or severe injury to the operator or others in the work area.

Crank the handwheel to raise or lower the table
according to the desired workpiece thickness.
Make sure the height scale is properly adjusted.
The power feed features two feed rates; 16 FPM
and 20 FPM. When running the machine, the
operator can control the feed speed by moving
the feed control knob .Moving the knob toward the
machine produces the 20 FPM feed speed, away
from the machine produces 16 FPM and a center
position places the gear box in neutral. See
Figure 36.
Figure 36. Feed speed adjustment knob.
The Model G1021Z is equipped with a depth limiter located on the bottom of the cutterhead casting just under the nameplate.See Figure 37. The
depth limiter controls maximum depth of cut to
1
/8".
With the limiting clip installed, you cannot cut
more than
1
/8" in a single pass.While cutting this
much material is possible, it is not recommended.
Take it slow and easy .The quality of your work will
be better and your planer will last longer.

Once the assembly is complete and the adjustments are done to your satisfaction, you are
ready to test the machine.
Turn on the power supply at the main panel.
Press the START button. Make sure that your finger is poised on the STOP button, just in case
there is a problem. The planer should run
smoothly, with little or no vibration or rubbing
noises. Strange or unnatural noises should be
investigated and corrected before operating the
machine further.
Test Run
DO NOT attempt to investigate or adjust the
machine while it is running. Wait until the
machine is turned off, unplugged and all
working parts have come to a rest before
you do anything!
If noises occur that cannot be found by visual
inspection, feel free to contact our service department for help.
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

Wood Characteristics
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 descriptions of defects will give you some possible
answers to problems you may encounter while
planing different materials. Possible solutions follow the descriptions.
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 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 and inspect the chipbreaker for proper
alignment. See the Adjustment Section.
Fuzzy Grain - Usually caused by surfacing lumber 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.
Glossy Surface - Usually caused by dull knives
taking shallow cuts at a slow feed speed.Surface
gloss will usually be accompanied by overheating. Often, lumber will be scorched and eventually, damage to knives will occur.If knives are sharp
on inspection, increase feed speed and/or cutting
depth.
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.
Snipe can be minimized by proper adjustment of
the planer’s 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 prob lem, consider planing lumber longer than your intended work length
and cut off the excess after planing is completed.
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.
Wavy Surface - Caused by poor knife height
adjustment, wavy surface appears when one
knife is taking deeper cuts than the rest of the
knives. Remedy by re-setting the knives to a tolerance of ± .003".
Pitch & Glue Build-up - Glue and resin build-up
on the rollers and cutterhead will cause overheating 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.
Chip Marks - Occur when chips aren’t 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-uniform (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).

SECTION 7: MAINTENANCE
Make a habit of inspecting your planer each time
you use it. Check for the following conditions and
repair or replace when necessary:
1. Loose mounting bolts.
2. Worn switch.
3. Worn or damaged cords and plugs.
4. Damaged V-belts .
5. Any other condition that could hamper the
safe operation of this machine.

Knives
The inspection and setting of the planer knives is
covered extensively in Section 5: Adjustments.
Table
The table and other non-painted surfaces on the
Model G1021Z should be protected against rust
and pitting.Wiping the table clean after every use
ensures that moisture from wood dust isn’t
allowed to trap moisture against bare metal surfaces.
Some woodworkers recommend using automotive paste wax on e xposed steel and cast iron surfaces.The wax provides a layer of protection, as
well as reducing friction between lumber and the
table, making cuts faster and smoother. Avoid
waxes that contain silicone or other synthetic
ingredients. These materials can find their way
into lumber that’s being worked, and can make
staining and finishing difficult. If you use paste
wax, make sure that it’s 100% Carnauba wax.

Lubrication
The Model G1021Z features factory-sealed bearings. A sealed bearing requires no lubrication
during its lifetime. Should a bearing fail, your
planer will probably develop a noticeable rumble,
which will increase when the machine is put
under load.If allowed to get worse, ov erheating of
the journal containing the bad bearing could
occur. If the bad bearing is not replaced, it will
eventually seiz e - possibly doing damage to other
parts of the machine.Bearings are standard sizes
and can be replaced through Grizzly.
Proper lubrication of other components of the
Model G1021Z are essential for long life and trouble-free operation. Below is a list of components
that require periodic lubrication. Schedules are
based on daily use. Adjust accordingly for your
level of use.
Columns/Lead Screws - The four columns
should be lubricated weekly with light oil.
Unfasten dust covers to gain access. The four
lead screws should be lubricated with general
purpose grease once a month.
Worm Gear - The worn gear should be inspected
monthly and lubricated when needed. Remove
the worm gear box to inspect. See parts diagram
for location.
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.
Gear Box - Gear box oil should be drained after
the first 20 hours of operation. See Figure 40.
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.
Drive Chain - The drive chain should be inspected and lubricated monthly.Check sprocket, chain
and cotter pin during inspection. Use a general
purpose grease. Some chains will have master
links instead of cotter pins.
Feed Rollers - The infeed/outfeed pressure
setscrews double as lubrication ports for the
rollers. See Figure 41. Add 1-2 drops of light
machine oil to all ports before each use. Daily
lubrication of feed rollers is crucial to the operation of your planer. Lubricate before start-up.
Apply a light oil, making sure that the lubricant
penetrates the bearing.

Clean and lubricate the chain sprockets as needed.The gearbox oil should be checked before the
first use. It is full when oil begins dribbling out of
the fill hole. Oil should be replaced yearly. Use
80W-90 gear oil in normal situations. Use 50W
motor oil for unheated, winter shops. See
Adjustment Section.
The lead screws and columns should be wiped of
any grease and dust build up once a week.They
should be relubricated with light machine oil. See
Figure 42.
