Safety Instructions For Power Tools
9. USE PROPER EXTENSION CORD. Make
sure your extension cord is in good condi­tion. Conductor size should be in accor­dance with the chart below. The amperage rating should be listed on the motor or tool nameplate. 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.

10. WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Non-slip footwear is recommended. Wear protective hair cov­ering to contain long hair.
11. ALWAYS USE SAFETY GLASSES. Also use face or dust mask if cutting operation is dusty. Everyday eyeglasses only have impact resistant lenses, they are NOT safe­ty glasses.
14. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest performance. Follow instructions for lubri­cating and changing accessories.
15. DISCONNECT TOOLS before servicing and changing accessories, such as blades, bits, cutters, and the like.
16. REDUCE THE RISK OF UNINTENTION­AL STARTING. Make sure switch is in off
position before plugging in.
17. USE RECOMMENDED ACCESSORIES.
Consult the owner’s manual for recom­mended accessories. The use of improper accessories may cause risk of injury.
18. CHECK DAMAGED PARTS. Before fur­ther use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, bind­ing of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.
19. NEVER LEAVE TOOL RUNNING UNAT­TENDED. TURN POWER OFF. Do not
leave tool until it comes to a complete stop.
20. NEVER USE UNDER THE INFLUENCE of alcohol or drugs, or when tired.
12. SECURE WORK. Use clamps or a vise to hold work when practical. It’s safer than using your hand and frees both hands to operate tool.
13. NEVER OVERREACH. Keep proper foot-
ing and balance at all times.
G8621 Heavy-Duty Sliding Table Shaper -3-
21. NEVER ALLOW UNSUPERVISED OR
UNTRAINED PERSONNEL TO OPER­ATE THE MACHINE. Make sure any
instructions you give in regards to the operation of the machine are approved, correct, safe, and clearly understood.
Additional Safety Instructions For Shapers
1. NEVER ALLOW YOUR HANDS to come
within 12 inches of the cutters. Never pass your hands directly over or in front of the cutter.
2. BLIND CUT WHENEVER POSSIBLE. This keeps the knives on the underside of the workpiece and provides a distance guard for the operator.
3. WHEN SHAPING CONTOURED WORK
and using a rub collar, NEVER start out at a corner. See the “Rub Collar” instructions further on in the manual.
4. WITH THE MACHINE UNPLUGGED, always rotate the spindle by hand with any new setup to ensure proper cutter clearance before starting the machine.
5. DO NOT SHAPE STOCK SHORTER than 12 inches without special fixtures or jigs. Where practical, shape longer stock and cut to size.
6. NEVER ATTEMPT to remove too much material in one pass. You are far more like­ly to enjoy safer and higher quality results if you allow the cutter to remove material in multiple passes.
7. THE DANGER OF kickback is increased when the stock has knots, holes, or foreign objects in it. Warped stock should be run through a jointer before attempting to run it through a shaper.
8. KEEP THE UNUSED PORTION of the cut­ter below the table surface.
9. THE USE OF PUSH STICKS as safety devices in some applications is smart; in others it can be quite dangerous. If the push stick comes in contact with the cutter on the end grain, it can fly out of your hand like a bullet—potentially causing serious injury. We recommend using some type of fixture, jig, or hold-down device as a safer alterna­tive. Always use the guard as described in the manual.
10. NEVER FORCE MATERIALS through the shaper. Let the cutters do the work. Excessive force is likely to result in poor cut­ting results and will cause dangerous kick­back conditions.
11. ALWAYS ensure that the cutters, fence, and spindle elevator knob have been tight­ened properly before beginning any opera­tion.
12. ALWAYS feed the work toward the cutters in the direction opposite of the cutter rota­tion. Also, using and maintaining a sharp cutterhead will greatly reduce the chance of kickback.
13. NEVER REACH BEHIND CUTTER to grab the workpiece. Your hand may suddenly be pulled into the cutter in the event of a kick­back.
14. IF AT ANY TIME YOU ARE EXPERIENC­ING DIFFICULTIES PERFORMING THE INTENDED OPERATION, STOP USING THE SHAPER! Then contact our service
department or ask a qualified expert how the operation should be performed.
Like all power tools, there is danger associ­ated with shapers. Accidents are frequently caused by lack of familiarity or failure to pay attention. Use this tool with respect and cau­tion to lessen the possibility of operator injury. If normal safety precautions are over­looked or ignored, serious personal injury may occur.
-4- G8621 Heavy-Duty Sliding Table Shaper
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.
SECTION 2: CIRCUIT REQUIREMENTS
220V Operation
The Model G8621 Shaper is furnished with a 3450 R.P.M., 5 H.P., Single-Phase 220V motor, push-button ON/OFF magnetic starter switch, for­ward-reverse switch and a cord set. Under nor­mal use, the motor draws approximately 25 amps @ 220V. We recommend a 30 amp circuit break­er. If frequent circuit failures occur when using the shaper, contact our service department.
The shaper motor must be connected to its own dedicated 30A circuit. The shaper should not share a circuit with any other machine, and the wires in the circuit should be rated for 30A. A standard 2-pole breaker is also necessary for use with the shaper.
We recommend using a NEMA-style L6-30 plug and outlet similar to that in Figure 1. You may also “hard-wire” the shaper directly to your panel, provided you place a disconnect near the machine. Check the electrical codes in your area for specifics on wiring requirements.
Grounding
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 an electric cord that has an equipment-grounding conductor which must be properly connected to a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.
Improper connections of the electrical-grounding conductor can result in the risk of electric shock. The conductor with green or green and yellow striped insulation is the electrical-grounding con­ductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment grounding conductor to a live terminal.
This equipment must be grounded. Verify that any existing electrical outlet and circuit you intend to plug into is actually grounded. Under no cir­cumstances should the grounding pin from any three-pronged plug be removed. Serious injury may occur.

Extension Cords
Wiring
We do not recommend the use of extension cords on 220V equipment. 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 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.
A wiring diagram is provided at the back of this manual should it be necessary to repair or revise the wiring. Always utilize a qualified electrician when doing any electrical work on this equip­ment.
We have covered some basic electrical requirements for the safe operation of your machine. These requirements are not necessarily comprehensive. You must be sure that your particular electrical configu­ration complies with local and state codes. Ensure compliance by checking with your local municipality or a licensed electrician.

Clean Up
Site Considerations
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 such as Grizzly’s G7895 Degreaser. Avoid chlorine­based solvents as they may damage painted sur­faces should they come in contact. Always follow the usage instructions on the product you choose to clean.
Do not use gasoline or other petroleum-based solvents to clean with. They have low flash points which make them extremely flammable. A risk of explosion and burning exists if these products are used. Serious personal injury may occur.
FLOOR LOAD
Your Model G8621 Shaper represents a moder­ately large weight load in a moderate sized foot­print. Most commercial shop floors will be ade­quate for the 770 lb. weight of the Model G8621. Some floors may require additional support. Contact an architect or structural engineer if you have any question about the ability of your floor to handle the weight.
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.
Do not smoke while using solvents. A risk of explo­sion or fire exists and may result in serious personal injury.
Many of the solvents commonly used to clean machinery can be toxic when inhaled or ingest­ed. Always work in well­ventilated 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.
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.
Make your shop “child safe.” Ensure that your workplace is inaccessible to children by closing and locking all entrances when you are away. Never allow visitors in your shop when assembling, adjusting, or operating equipment.

SECTION 4: ASSEMBLY
Beginning Assembly
Most of your Model G8621 Shaper 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.
Keep loose clothing rolled up and out of the way of machinery and keep hair pulled back.
Disconnect power to the machine when perform­ing any maintenance or assembly. Failure to do this may result in serious personal injury.
Handwheel
The handwheel, pre-installed at the factory, is made of cast iron. It is used to raise and lower the spindle to accommodate the height required by your cutter.
Thread the crank handle onto the handwheel.
Wear safety glasses dur­ing the entire assembly process. Failure to com­ply may result in serious personal injury.
Some metal parts may have sharp edges on them after they are formed. Please examine the edges of all metal parts before handling them. Failure to do so could result in injury.
