SECTION 1: SAFETY

For Your Own Safety, Read Instruction

Manual Before Operating this Machine

The purpose of safety symbols is to attract your attention to possible hazardous conditions. This

manual uses a series of symbols and signal words which are intended to convey the level of

importance of the safety messages. The progression of symbols is described below. Remember

that safety messages by themselves do not eliminate danger and are not a substitute for proper

accident prevention measures.

Indicates an imminently hazardous situation which, if not avoided,

WILL result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,

COULD result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,

MAY result in minor or moderate injury. It may also be used to alert

against unsafe practices.

This symbol is used to alert the user to useful information about

proper operation of the machine.

Additional Safety Instructions for Planers

1. INSTRUCTION MANUAL. This machine

presents significant safety hazards to

untrained users. Read/understand this

entire manual before starting the planer.

8. CUTTING LIMITATIONS. The planer may

kick out a workpiece at the operator or be

damaged if pushed beyond these limits:

•

Maximum Depth of Cut ..................¹⁄8

Minimum Board Length.................6¹⁄2

Minimum Board Thickness .............¹⁄4

2. REACHING INSIDE PLANER. Never

reach inside the planer or remove covers

when the planer is connected to power.

Maximum # of Boards at One Time..1

9. CLEAN STOCK. Planing stock with nails,

staples, or loose knots MAY cause debris

to kick out at the operator and WILL dam-

age your cutters when they contact the

cutterhead. Always thoroughly inspect and

prepare stock to avoid these hazards.

3. INFEED CLEARANCE SAFETY. The

infeed roller is designed to pull material

into the cutterhead. Always keep hands,

clothing, and long hair away from the

infeed roller during operation to prevent

serious injury.

10. REMOVING JAMMED WORKPIECES. To

avoid serious injury, always stop the planer

and disconnect power before removing

jammed workpieces.

4. BODY POSITION WHILE OPERATING.

The workpiece may kick out during opera-

tion. To avoid getting hit, stand to the side

of the planer during the entire operation.

11. DULL/DAMAGED CUTTERS. The planer

may kick out a workpiece at the operator or

give poor finish results if it is operated with

dull or damaged cutters.

5. PLANING CORRECT MATERIAL. Only

plane natural wood stock with this planer.

DO NOT plane MDF, plywood, laminates,

or other synthetic products.

12. UNPLUGGING DURING ADJUSTMENTS.

When connected to power, the planer can

be accidentally turned ON. Always discon-

nect power when servicing or adjusting the

components of the planer.

6. GRAIN DIRECTION. Planing across the

grain is hard on the planer and may cause

the workpiece to kick out. Always plane in

the same direction or at a slight angle with

the wood grain.

12. WORKPIECE CLEARANCE. Always verify

workpiece has enough room to exit the

planer before starting.

7. LOOKING INSIDE PLANER. Wood chips

fly around inside the planer at a high rate

of speed. DO NOT look inside the planer or

remove guards/covers during operation.

No list of safety guidelines can be complete.

Every shop environment is different. Always

consider safety first, as it applies to your

individual working conditions. Use this and

other machinery with caution and respect.

Failure to do so could result in serious per-

sonal injury, damage to equipment, or poor

work results.

Like all machinery there is potential danger

when operating this machine. Accidents are

frequently caused by lack of familiarity or

failure to pay attention. Use this machine

with respect and caution to lessen the pos-

sibility of operator injury. If normal safety

precautions are overlooked or ignored, seri-

ous personal injury may occur.

Test Run

Tighten V-Belts

The final step in the set up process must be done

after approximately 16 hours of operation. During

this first 16 hours, the V-belts will stretch and seat

into the pulley grooves. After this time, the V-belts

must be retensioned or belt failure will occur

quickly. Refer to Page 22 when you are ready to

perform this important adjustment.

Loose hair and cloth-

ing could get caught

in machinery and

cause serious person-

al injury. Keep loose

clothing rolled up and

long hair tied up and

away from machinery.

Note: Pulleys and belts run very hot. This is a

normal condition. Allow them to cool before mak-

ing adjustments. A collection of black belt dust at

the bottom of the belt housing is a normal during

the life of the machine.

To perform a test run:

1. Read the entire instruction manual, and

make sure oil is in the gearbox.

1. Put on safety glasses.

2. Unless your workpiece starts very flat, sur-

face plane the workpiece on a jointer until it

is flat.

3. Adjust table height to slightly lower than your

workpiece height to ensure the first cut is as

light as possible.

4. Start the planer.

5. Place the flat side of the board down on the

table, and feed the workpiece through the

planer, making sure not to stand directly in

front or behind the workpiece.

Loose hair and cloth-

ing could get caught in

machinery and cause seri-

ous personal injury. Keep

loose clothing and long

hair away from moving

machinery.

—If the cut is too heavy and bogs down the

planer, turn the planer OFF immediately,

allow it to come to a complete stop, remove

the workpiece, and repeat Steps 3–5.

6. Measure your workpiece thickness and

adjust the table height as necessary to take

a lighter or heavier pass, depending on your

needs.

Operation Tips

Feed Speed

•

Inspect lumber for defects, warping, cup-

ping, twisting, and for foreign objects (nails,

staples, imbedded gravel, etc,). If you have

any question about the quality of your lum-

ber, do not use it. Remember, wood stacked

on a concrete floor can have small pieces of

stone or concrete pressed into the surface.

The infeed and outfeed rollers power the stock

through the planer while keeping boards flat and

providing a consistent rate of movement.

The power feed features 16 FPM and 20 FPM

feed rates. The speed should be changed ONLY

when the machine is running.

•

Use the full width of the planer. Alternate

between the left, the right, and the middle

when feeding lumber into the planer. Your

cutters will remain sharp much longer.

Figure 10 illustrates the three different positions

of the feed control knob. Moving the knob toward

the machine (Position A) produces the 20 FPM

feed speed; moving away from the machine

(Position C) produces 16 FPM; and moving the

knob to the center position (Position B) places the

gearbox in neutral.

•

Scrape all glue off joined boards before plan-

ing.

Plane ONLY natural wood fiber. DO NOT

plane MDF, plywood, laminates, or other

synthetic products.

NOTICE

Change the speeds when the planer is run-

ning, but DO NOT attempt to change speeds

during any cutting operations or damage to

the gearbox will result.

•

Plane wood with the grain. Never feed

end-cut or end-grained lumber into your

planer.

Do not use boards with loose or large knots,

splits, crossgrain or other obvious blemishes

or defects. They can damage the machine

and pose the possibility of operator injury.

�

•

Keep your work area clear.

When making multiple passes 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.

•

Avoid planing wood with a high water con-

tent. Wood with more than 20% moisture

content or wood exposed to excessive mois-

ture (such as rain or snow), will plane poorly

and cause excessive wear to the cutters and

motor. Excess moisture can also hasten rust

and corrosion of the planer and/or individual

components.

The height of the bed rollers will vary, depend-

ing on the type of material you intend to plane,

but as a general rule keep the roller height within

0.002"–0.020" above the table. When planing

rough stock, set the rollers high to keep the lum-

ber from dragging along the bed. When planing

milled lumber, set the rollers low to help minimize

snipe.

Figure 12. Bed roller controls (only one side

shown).

3. Raise or lower the rollers by rotating the

adjusters to reach your desired height.

4. Verify both sides of the bed roller are at the

same height and lock them in position with

the locking set screws.

5. Double check the roller heights to make sure

they did not move when you locked them (if

they did, repeat the procedure).

Figure 11. Bed roller height range.

To ensure accurate results and make the adjust-

ment process quicker and easier, we recommend

using a Rotacator (see Page 20) to gauge the

bed roller height from the table. If a Rotacator is

not available, a straightedge and feeler gauges

can be used, but care must be taken to achieve

satisfactory results.

Note: Misaligned bed rollers can be the root of

many planing problems, such as:

• Workpiece chatter and/or noisy operation

• Washboard surfaces

• Workpiece rotating during planing

• Tapered cuts

• Binding, causing the workpiece to jam

SECTION 6: MAINTENANCE

Cleaning

Always disconnect power

to the machine before

performing maintenance.

Failure to do this may

result in serious person-

Vacuum excess wood chips and sawdust, and

wipe off the remaining dust with a dry cloth—this

ensures moisture from wood dust does not remain

on bare metal surfaces. Treat all unpainted cast

iron and steel with a non-staining lubricant after

cleaning. We recommend products like SLIPIT^®,

G96^®Gun Treatment, or Boeshield^®T-9 (see

al injury.

Schedule

Page 21 for more details).

For optimum performance from your machine,

follow this maintenance schedule and refer to any

specific instructions given in this section. Refer to

Lubrication on Page 23 for specific lubrication

instructions.

V-Belts

Adjust/replace belts by using the hex nuts on

the motor mount bolt (Figure 20) to control the

tension. The correct tension for the V-belts is ¹/4

Daily:

•

Clean unpainted cast iron part of table

Lubricate feed rollers

deflection when pushed in the center with moder-

ate pressure. After the first 16 hours of belt life,

retension them, as they will stretch and seat dur-

ing this time.

Weekly Maintenance:

•

Clean cutterhead

•

Lubricate four columns

Always replace the V-belts with a matched set of

3 belts, or belt tension may not be even among

the 3 belts and can cause premature belt failure.

Monthly Check:

•

Inspect V-belt tension, damage, or wear

•

Clean/vacuum dust buildup from inside cabi-

net and off motor

•

Lubricate worm gear

Lubricate chain

Lubricate drive chain

Yearly:

•

Change gear box oil (should be performed

after the first 20 hrs when planer is new)

Figure 20. Motor mount bolt.

Lubrication

The Model G1021X features factory-sealed bear-

ings. Should a bearing fail, your planer will prob-

ably develop a noticeable rumble/vibration, which

will increase when the machine is put under load.

Bearings are standard sizes and can be replaced

through Grizzly.

Fill

Proper lubrication of other planer components 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.

Drain

Figure 21. Gearbox oil drain/fill locations

(sprockets and chains removed for clarity).

Drive Chain: The drive chain should be inspected

and lubricated monthly. Check sprockets, chains

and cotter pins during inspection. Some chains

will have master links instead of cotter pins.

Always disconnect power

to the machine before

lubricating! Failure to do

this may result in serious

personal injury.

Feed Rollers: Daily lubrication of feed rollers is

crucial to the operation of your planer. Lubricate

before start-up. Each end of each power feed roll-

er has an oiling port located on the top of the head

casting (Figure 22). Apply a SAE 30W oil, making

sure that the lubricant penetrates the bearing.

Columns/Lead Screws: The four columns should

be lubricated weekly with SAE 30W oil. Unfasten

dust covers to gain access. The four lead screws

should be lubricated with general purpose grease

once a month.

Worm Gear: The worm gear should be inspected

monthly and lubricated with general purpose

grease 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 with general

purpose grease when needed.

Gear Box: Gear box oil should be changed after

the first 20 hours of operation (see Figure 21). It

is not necessary to remove the chain drive cover

to access the fill/drain plugs, but doing so will give

you easier access.

Figure 22. Tension screw locations.

Replace with 80W-90W 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.

SECTION 7: SERVICE

In addition, each cutter has a reference dot on

one corner. As the cutter is rotated, the reference

dot location can be used as an indicator of which

edges are used and which are new. When the

reference dot revolves back around to its starting

position, the cutter should be replaced.

Always

disconnect

power to the machine

before performing ser-

vice adjustments. Failure

to do this may result in

serious personal injury.

About Service

This section is designed to help the operator with

adjustments that were made at the factory and

that might also need to be made during the life of

the machine.

Figure 23. Cutter rotating sequence.

This section is provided for your convenience—

it is not a substitute for the Grizzly Service

Department. If any adjustments arise that are not

described in this manual, then feel free to call

Tech Support at (570) 546-9663.

To rotate or change a carbide cutter:

1. DISCONNECT THE PLANER FROM THE

POWER SOURCE!

Similarly, if you are unsure of how to perform any

procedure in this section, Tech Support will be

happy to guide you through the procedures or

help in any other way.

2. Remove any sawdust from the head of the

carbide cutter Torx screw.

3. Remove the Torx screw and carbide cutter.

4. Clean all dust and dirt off the cutter and the

cutterhead pocket from which the cutter was

removed, and replace the cutter so a fresh,

sharp edge is facing outward.

Rotating/Changing

Carbide Cutters

Note: Proper cleaning is critical to achieving

a smooth finish. Dirt or dust trapped between

the cutter and cutterhead will slightly raise the

cutter, and make a noticeable marks on your

workpieces the next time you plane.

Tools Needed:

T-Handle Wrench w/T20 Torx Bit...................... 1

Qty

The cutterhead is equipped with 72 indexable car-

bide cutters. Each cutter can be rotated to reveal

any one of its four cutting edges. Therefore, if one

cutting edge becomes dull or damaged, simply

rotate it 90˚ to reveal a fresh cutting edge, as

shown in Figure 23.

5. Lubricate the Torx screw threads with a

light machine oil, wipe the excess oil off the

threads, and torque the Torx screw to 48-50

inch/pounds.

Note: Excess oil may squeeze between the

cutter and cutterhead, thereby lifting the cut-

ter slightly and affecting workpiece finishes.

Maximum Allowable Tolerances:

Cutterhead/Table Side-to-Side..................0.002"

Wrench or Socket 12mm................................... 1

Head Casting/Table Front/Back ................0.020"

The chain drive transfers movement from the

handwheel to elevate the table. The chain drive

can be adjusted to remove slack if the chain

stretches over time or during table leveling pro-

cedures.

Table parallelism is critical to the operation of the

machine. As such, it is essential that the table is

parallel with the cutterhead (within 0.002") from

side-to-side, as illustrated in Figure 25.

To adjust the chain tension:

��

1. DISCONNECT THE PLANER FROM THE

POWER SOURCE!

��

2. Remove the motor access panel.

�

��

�

3. Loosen the two locking bolts and move the

idler sprocket until chain play has been elimi-

nated (Figure 24).

��

Figure 25. Side-to-side parallelism of table and

cutterhead.

How the table sits in relation to the head casting

from front-to-back is also important (see Figure

26). Because the feed rollers, pressure bar, and

chip breaker will be adjusted off the table position,

the tolerances on the front-to-back positioning are

not as critical as the cutterhead/table side-to-side

positioning. Therefore, the maximum allowable

tolerance for the front-to-back parallelism is not

more than 0.020".

NOTICE

��

DO NOT let the chain fall off the sprock-

ets—returning it to its proper location with-

out changing the table adjustments can be

very difficult.

6. Carefully turn the sprocket (clockwise to

lower the table; counterclockwise to raise the

table) just enough to position the next tooth at

the marked location, then fit the chain around

sprocket again.

Table Parallelism Inspection

Use your Rotacator to inspect the table parallel-

ism. If you do not have a Rotacator, a wood block

and feeler gauges may be used, but extra care

must be taken to ensure accuracy. If the table is

not within the maximum allowable tolerances, it

must be adjusted.

7. Repeat Steps 4–6 with each sprocket that

needs to be adjusted until the table-to-

cutterhead clearance is within 0.016" from

one side to the other.

Table Parallelism Adjustments

The table is adjusted by turning the chain sprock-

ets underneath the table for movements over

0.016" or by adjusting how the table is mounted

on the columns for movements under 0.016".

8. Make sure the chain is properly fitted on the

sprockets and tighten the idler sprocket and

lock bolts.

9. Micro-adjust the table position by loosening

the cap screws shown in Figure 27 and lifting

the table upward or downward until the table

and cutterhead are in alignment.

NOTICE

When making adjustments, tighten fasten-

ers after each step to ensure the accuracy

of your tests. When adjusting the chain

sprockets, keep in mind that if the chain

becomes too loose, it will fall off of all the

sprockets. Returning it to its proper loca-

tion can be frustrating.

Note: This process may require adjusting the

columns on both the left and right hand sides

until you find the correct combination.

To adjust the table parallelism:

1. DISCONNECT THE PLANER FROM THE

POWER SOURCE!

2. Remove the cabinet panel and locate the

chain on the underside of the table.

3. Loosen the idler sprocket (see Chain Tension

instructions on Page 25).

4. Move the chain away from only the sprocket

you want to adjust so only that sprocket can

be turned independent of the chain.

Figure 27. Close up of table micro-adjustment

screws (one side shown only).

Note: If the left side of the table is too high,

the left two sprockets will need to be adjusted.

Each tooth on the sprocket represents .016"

of vertical movement as the cogs are turned.

Make sure, as you turn the sprockets, to keep

an accurate tooth count to ensure that the

table is adjusted equally.

5. Mark the location of one tooth in the sprocket

that you are adjusting.

roller back and forth.

Figure 28. Cutter edge at bottom dead center.

To ensure accurate results and make the adjust-

ment process quicker and easier, we recommend

using a Rotacator (see Page 20) for these adjust-

ments.

7. Adjust the height of the infeed roller on the

same side as the Rotacator to the specifica-

tion given at the beginning of this procedure,

using the zero setting of the Rotacator as a

reference point. Figure 30 shows the jam nut

and set screw for adjusting the roller height.

If a Rotacator is not available, a pair of even-sized

wood blocks and a 0.40" feeler gauge can be

used, but care must be taken to achieve accurate

results.

8. Repeat Steps 6 & 7 on the left-hand side of

the infeed roller.

To set the height of the infeed and outfeed roll-

ers and the chip breaker using a Rotacator:

9. Double-check and micro-adjust both sides

of the infeed roller, then carefully lock both

sides in place.

system as a safety feature. The anti-kickback

fingers hang from a rod suspended across the

cutterhead casting. The anti-kickback fingers

should be inspected regularly.

Check the fingers (Figure 36) to ensure that they

swing freely and easily. If the fingers do not swing

freely and easily, clean them with a wood resin

solvent.

Proper pulley alignment (see Figure 37) prevents

premature belt wear. The pulleys are properly

aligned when they are parallel and in the same

plane as each other. Use a straightedge on the

edge of the pulleys to judge alignment.

Do not apply oil or other lubricants to the anti-

kickback fingers. Oil or grease will attract dust,

restricting the free movement of the fingers.

Proper operation of the anti-kickback fin-

gers are essential for the safe operation of

this machine. Failure to ensure that they

are working properly could result in serious

operator injury.
