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).

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 -
1.25 hex nut and washer provided.
4. Attach the handle to the outer edge of the handwheel. The handle threads into the hole on the handwheel.

Extension Rollers
Speed Change Knob
The infeed and outfeed extension rollers support the work as it goes through the machine.
TO MOUNT THE EXTENSION ROLLERS:
1. Thread three (3) 8mm setscrews into the
mounting bracket of the extension rollers. The setscrew holes are located just below the mounting holes. Just star t them into the holes for now.
2. Use three (3) hex bolts and washers to mount the extension rollers. See Figure 5. Make sure the roller assembly is oriented as shown in Figure 6.
3. Position a straightedge on the table bed, so it lays on the table and suspends over the extension rollers.See Figure 6.

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!

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.
Jack Screw
Spring
Figure 13. Typical placement of 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 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!

The knives are locked into the cutterhead with wedge-type gibs and gib bolts.Jack screws under the knives may be substituted with springs to help in the setting process. It is advised that the jack screws be removed when using the springs. 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 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.

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.

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.

NOTICE
If you take a cut that is too large, the planer will bog down noticeably. The motor may even stall. If this happens, turn off the power immediately, lower the table, and remove your workpiece. Re-adjust your table to allow a lesser cut and repeat your operation.
NOTICE
The feed rate should be set while the plan­er is running but before feeding lumber into it. DO NOT attempt to change speeds after the cutting operation has begun.

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.

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.
General
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.

-34- G1021Z 15" Planer
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
