SECTION 1: SAFETY WARNING For Your Own Safety Read Instruction Manual Before Operating This Equipment The purpose of safety symbols is to attract your attention to possible dangers. This manual uses a series of symbols which are intended to convey the level of criticality of the safety message. 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.
WARNING Safety Instructions For Power Tools 9. USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When using an extension cord, be sure it is rated Hard Service (grade S) or better. Conductor size must be 16 A.W.G. for cords up to 100 feet in length. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Your extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords if they become damaged.
WARNING Additional Safety Instructions For Planers 1. 2. 3. Ensure that the machine sits firmly on the floor before use. Any “wobbles” must be corrected by shimming or blocking before operation. This machine is not designed to process any other material except wood. 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.
SECTION 2: CIRCUIT REQUIREMENTS 220V Operation Grounding The G1021 Planer motor is wired to operate at 220V only. A cordset without a 220V plug is included with the Model G1021. Plugs and receptacles can be purchased at your local hardware store or home center. When connecting to 220V, ensure that the electrical circuit is in fact a 220V circuit. Contact your local electrical contractor if uncertain about converting to 220V operation.
SECTION 3: INTRODUCTION Commentary Grizzly Industrial, Inc. is proud to offer the Model G1021 15" Planer. The G1021 is part of Grizzly’s growing family of fine woodworking and metalworking machinery. When used according to the guidelines stated in this manual, you can expect years of trouble-free, enjoyable operation. The Model G1021 is intended for home and professional use.
Unpacking The bandsaw is shipped from the factory in a carefully packed carton. If you find the machine to be damaged after you’ve signed for delivery and the truck and driver are already gone, you will need to file a freight claim with the carrier. Save the containers and all packing materials for inspection by the carrier or their agent. Without the packing materials, filing a freight claim can be difficult. If you need advice regarding this situation, please call us immediately.
Clean Up The unpainted surfaces are coated with a waxy oil to protect it from corrosion during shipment. Remove the protective coating with common paint thinner (mineral spirits) and paper towels. Do not use gasoline or other petroleum based solvents because of their extremely low flash points. Do not use chlorine-based solvents – if you happen to splash some onto a painted surface, you’ll ruin the finish. WARNING Follow the safety rules listed below when working with solvents. 1.
SECTION 4: ASSEMBLY Overview Most of your G1021 Planer has been assembled at the factory, but some parts must be assembled or installed after delivery. We have organized the assembly process into steps. Please follow along in the order presented here. TOOLS REQUIRED: Most of the tools required for assembly are included with the planer. However, you will also need a Phillips® and regular screwdriver as well as feeler gauge for adjustments later on. Figure 2. Stand crossbracing in place.
Planer Unit TO MOUNT THE PLANER: 1. Using the lifting handles shown in Figure 4, place the planer on the stand and align the four holes in the base over the four mounting holes in the stand. 2. Secure the planer base to the stand with the four hex bolts, nuts, washer and fender washers provided. CAUTION This planer is relatively heavy and awkward to handle. We strongly recommend that you get assistance. It will require at least two people to lift the planer onto the stand.
Handwheel Knife Setting Jig The handwheel is used to raise and lower the planer table. Each complete revolution raises the table 5⁄32" (4mm). The knife setting jig has been provided to make knife setting quick and easy. See Figure 7. TO ASSEMBLE THE KNIFE SETTING JIG: TO MOUNT THE HANDWHEEL: 1. Place the handwheel over the keyed shaft on the planer body. Make sure the key on the shaft and the keyway on the handwheel line up. The handwheel shaft is at the front right of the planer. See Figure 6. 2.
Extension Rollers Dust Port The extension rollers can be attached now, but it may be easier to make all the necessary adjustments to the planer before attaching them. The G1021 Planer features a 4" dust port for use with a dust collection system. TO ATTACH THE EXTENSION ROLLERS: 1. 2. Use the hex bolts and washers to mount the extension rollers. See Figure 8. Ensure that the top of the rollers are above the extension roller frame. Finger-tighten the mounting bolts for now.
SECTION 5: ADJUSTMENTS Overview A. The switch is thermally protected and magnetically controlled and features push buttons to turn the planer on and off. Once assembly has been completed, your G1021 15" Planer requires just a few adjustments to ready it for use in your shop. 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.
Gauge Block Table Adjustment Before attempting any table adjustments, you will need to construct a gauge block. See Figure 11. 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. Do not use the planer during the milling process since the gauge block is needed first to check and make planer adjustments.
If the gap difference from one side to the other is greater than 0.004", but less than 0.016", go to step 5. Knife Inspection 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. The Model G1021 Planer has a three-knife cutterhead. The cutterhead is located in the head casting and rotates on two sealed bearings.
Knife Setting The process of setting the knives in the cutterhead will come into play whenever you sharpen or replace, or after determining that setting is necessary during the initial setup. The knives are locked into the cutterhead with wedge type gibs. Springs under each knife provide an upward pressure to help ease the setting process. Figure 14. Adjusting knife height. 4. If the knife bottoms out on the gauge block, repeat steps 1, 2 and 3, but start on the opposite side of the cutterhead. 5.
4. While holding the position of the knife setting jig, tighten the gib bolts down again in the cutterhead. Tighten the bolts evenly from the outside, working toward the middle. See Figure 16. 5. Repeat these steps for the other two knives. 3. Place the gauge block on the table directly under the cutterhead. Using a one millimeter (0.05") feeler gauge between the gauge block and the cutterhead, raise the table until one of the knives just touches the feeler gauge.
6. If an adjustment is necessary, loosen the locknuts and turn the setscrews. See Figure 18. Stop turning when the bottom of the chip breaker just touches the gauge block. 7. Re-tighten both locknuts 8. Replace the exhaust hood. 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: Figure 18.
6. Repeat steps 1-5 for the opposite side of the roller. Repeat all steps for the outfeed roller. Feed Roller Pressure Feeler gauge measurement should equal 0.040". TO ADJUST ROLLER HEIGHT: 1. Remove the drive chain cover 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.
4. Remove the springs that are in the holes left by the setscrews. See Figure 22. 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. TO ADJUST THE BED ROLLERS: 1. Ensure that power is disconnected and lay a high quality straightedge across both table rollers. Use a try square to keep the straightedge perpendicular to the table. 2.
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. Setscrews Setscrews Mounting Bolts Figure 24. Adjusting bed roller height.
Anti-Kickback Belts The Model G1021 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 26. 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.
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. Loosen the two bolts that hold the motor/pulley assembly to the planer. 2. Insert a wooden lever of suitable strength and pry the motor up to increase belt tension. See Figure 28. 3. Maintain lever position and check belt tension. Re-adjust if necessary. 4.
3. 4. The oil level in the gearbox should be to the bottom of the filler plug near the top of the gearbox. Top off with 80-90 wt. gear oil if necessary. Use 50 wt. motor oil if you are working in an unheated winter shop. See Figure 30. Drain and replace the oil yearly. See Figure 31. Extension Rollers N. EXTENSION ROLLERS If you elected to wait to install the extension rollers during the assembly process, install the extension rollers now. Refer to the Assembly Section.
Thickness Scale 4. Re-measure the board and compare your results with the scale. If there is a discrepancy, loosen the scale adjustment screw and correct the position. See Figure 33. The thickness scale, located below the handwheel, can be adjusted for accuracy. However, the machine must be operated to adjust the thickness scale. Follow the directions in the Operations Section for test running before attempting to make these adjustments. TO ADJUST THE SCALE: 1. 2. 3.
SECTION 6: Operations WARNING The Model G1021 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 G1021 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.
Power Feed Handwheel 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. Figure 35. Crank the handwheel to raise or lower the table according to the desired workpiece thickness.
Test Run Wood Species Once the assembly is complete and the adjustments are done to your satisfaction, you are ready to test the machine. 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 brief listing of common hard and soft woods in relation to their shear strengths and planing difficulty is listed below.
Planing Difficulties 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.
SECTION 7: MAINTENANCE General Knives Make a habit of inspecting your planer each time you use it. Check for the following conditions and repair or replace when necessary. We recommend that dull knives be taken to a professional knife sharpener. Improperly sharpened knives can cause a number of defects to lumber and put unnecessary load on the motor and drive systems. If you can avoid sharpening knives yourself, allow them to be handled by a trained sharpener. 1. Loose mounting bolts. 2. Worn switch.
Lubrication The Model G1033 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, overheating of the journal containing the bad bearing could occur. If the bad bearing is not replaced, it will eventually seize - possibly doing damage to other parts of the machine.
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 80-90 Wt. gear oil in normal situations. Use 50 wt. motor oil for unheated, winter shops. See Adjustment Section. Lubrication Ports 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.
