A. GROUNDING INSTRUCTIONS 

1. In the event of a malfunction or breakdown, grounding provides a path of least resistance for 

electric current to reduce the risk of electric shock. This tool is equipped with an electric cord 
having an equipment-grounding conductor and 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. 

2. Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by 

a qualified electrician. 

3. Improper connection of the equipment-grounding conductor can result in a risk of electric 

shock. The conductor with insulation having an outer surface that is green with or without 
yellow stripes is the equipment-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. 

4. Check with a qualified electrician or service personnel if the grounding instructions are not 

completely understood, or if in doubt as to whether the tool is properly grounded. 

5. Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles 

that accept the tool's plug. 

6. Repair or replace damaged or worn cord immediately. 
7. This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in 

Sketch A in Figure (below) (120V). The tool has a grounding plug that looks like the plug 
illustrated in Sketch A in Figure (below). A temporary adapter, which looks like the adapter 
illustrated in Sketches B and C, may be used to connect this plug to a 2-pole receptacle as 
shown in Sketch B if a properly grounded outlet is not available. The temporary adapter 
should be used only until a properly grounded outlet can be installed by a qualified 
electrician. The green-colored rigid ear, lug, and the like, extending from the adapter must be 
connected to a permanent ground such as a properly grounded outlet box. 

8. USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. 

When using an extension cord, be sure to use one heavy enough to carry the current your 
product will draw. An undersized cord will cause a drop in line voltage resulting in loss of 
power and overheating. Table (below) shows the correct size to use depending on cord 
length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the 
gauge number, the heavier the cord. 

9. Install equipment so that the power supply cord can be pulled out without hindrance in event 

of emergency. 

1. For your own safety read instruction manual before operating tool. 
2. Wear eye protection. 
3. Replace cracked wheel immediately. 
4. Always use guards and eye shields. 
5. Do not over tighten wheel nut. 
6. Use only flanges furnished with the grinder. 
7. REMOVE ADJUSTING KEYS AND WRENCHES. From habit of checking to see that keys and 

adjusting wrenches are removed from tool before turning it on. 

8. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents. 
9. DON'T USE IN DANGEROUS ENVIRONMENT. Don't use power tools in damp or wet 

locations, or expose them to rain. Keep work area well lighted. 

10. Risk of injury due accidental starting. Do not use in an area where children may be present. 
11. DON'T FORCE TOOL. It will do the job better and safer at the rate for which it was designed. 
12. USE RIGHT TOOL. Don't force tool or attachment to do a job for which it was not designed. 
13. WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets, or 

other jewelry that might get caught in moving parts. Nonslip footwear is recommended. Wear 
protective hair covering to contain long hair. 

14. ALWAYS USE SAFETY GLASSES. Everyday eyeglasses only have impact resistant lenses, 

they are NOT safety glasses. Also use face or dust mask if cutting operation is dusty. 

15. SECURE WORK. Use clamps or a vise to hold work when practical. It's safer than using your 

hand and it frees both hands to operate tool. 

16. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best performance and to 

reduce the risk of injury to persons. Follow instructions for lubricating and changing 
accessories.
