be used to alert against unsafe practices. This symbol is used to alert the user to useful information

about proper operation of the equipment.

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

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.

Minimum Gauge for Extension Cords

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.

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.

18. CHECK DAMAGED PARTS. Before fur-

ther 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.

Additional Safety Instructions For Grinders

1. Wear a face shield and/or safety goggles.

2. Use clamps and supports to sharpen tools.

3. Grinding creates sparks. Make sure your work area is free of combustible materials.

4. Dress the grinding wheel when its surface becomes rutted or uneven. Replace the wheel if the wear or damage becomes excessive.

5. Do not use a wheel that is cracked or chipped.

6. Be sure the grinder is mounted on a stable surface.

7. If you are unclear about operating the machine, don’t use it. Please call our service department if you have questions about any element of this machine’s operation.

8. Use care when handling sharpened cutting tools.

Operating 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).

Like all power tools, there is danger associated with the Model G8220 Wet/Dry Bench Grinder. 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.

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 person injury, damage to equipment or poor work results.

110V Operation

SECTION 2: CIRCUIT REQUIREMENTS

A 15-amp fuse or circuit breaker should be used when connecting this Bench Grinder. Circuits rated any higher are not adequate to protect the motor from power surges.

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

If you find it necessary to use an extension cord with the Model G8220, make sure the cord is rated Hard Service (grade S) or better. Refer to the chart in the standard 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. 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 injury may occur.

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 hav-

ing an equipment-grounding conductor. See Figure 1. The outlet must be properly installed

and grounded in accordance with all local codes and ordinances.

The Model G8220 is wired for 110V, single phase operation only. The

⁄4

HP motor will draw 1 amp at 110V. If you operate this grinder on any circuit that is already close to its capacity, it might blow a fuse or trip a circuit breaker. However, if an unusual load does not exist and a power failure still occurs, contact a qualified electrician or our service department.
