IMPORTANT SAFETY INSTRUCTIONS (For All Tools) WARNING: WHEN USING ELECTRIC TOOLS, BASIC SAFETY PRECAUTIONS SHOULD ALWAYS BE FOLLOWED TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, AND PERSONAL INJURY, INCLUDING THE FOLLOWING: READ ALL INSTRUCTIONS. 1. KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries. 2. CONSIDER WORK AREA ENVIRONMENT. Don't use power tools in damp or wet locations. Keep work area well lit. Don't expose power tools t o rain. Don't use tool in presence of flammable liquids or gases. 3. KEEP CHILDREN AWAY. All visitors should be kept away from work area. Don't let visitors contact tool or extension cord. 4. STORE IDLE TOOLS. When not in use, tools should be stored in dry, and high or locked-up place - out of reach of children. 5. DON'T FORCE TOOL. It will do the job better and safer at the rate for which it was intended. 6. USE RIGHT TOOL. Don't force small tool or attachment t o do the job of a heavy-duty tool. Don't use tool for purpose not intended; for example, don't use circular saw for cutting tree limbs or logs. 7. DRESS PROPERLY. Don't wear loose clothing or jewelry. They can be caught in moving parts. Rubber gloves and non-skid footwear are recommended when working outdoors. Wear protective hair covering t o contain long hair. 8. USE SAFETY GLASSES. Also use face or dust mask if cutting operation is dusty. 9. DON'T ABUSE CORD. Never carry tool by cord or yank it t o disconnect from receptacle. Keep cord from heat, oil, and sharp edges. IO. SECURE WORK. Use clamps or a vise t o hold work. It's safer than using your hand and it frees both hands t o operate tool. 11. DON'T OVERREACH. Keep proper footing and balance at all times. 12. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and safer performance. Follow instructions for lubricating and changing accessories. Inspect tool cords periodically and if damaged, have repaired by authorized service facility. Inspect extension cords periodically and replace if damaged. Keep handles dry, clean, and free from oil and grease. 13. DISCONNECT TOOLS. When not in use, before servicing, and when changing accessories, such as blades, bits, cutters. 2 14. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking t o see that keys and adjusting wrenches are removed from tool before turning it on. 15. AVOID UNINTENTIONAL STARTING. Don't carry tool with finger on switch. Be sure switch is OFF when plugging in. 16. EXTENSION CORDS. Make sure your extension cord is in good condition. When using an extension cord, be sure t o use one heavy enough t o carry the current your product will draw. A n undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 1 shows the correct size t o use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.
