SAFETY INSTRUCTIONS
(For All Tools)
WARNING: WHEN USING ELECTRICTOOLS, BASIC SAFETY
PRECAUTIONSSHOULD 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. Keepwork area well
lit. Don't expose power tools to 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 IDLETOOLS. When not in use, tools should bestored in dry, andhigh
or locked-up place
- out of reach of children.
5. DON'T FORCE TOOL. It will do thejob betterand safer atthe ratefor which
it was intended.
6. USE RIGHT TOOL. Don't force small tool or attachment to do the job of a
heavy-dutytool. Don't usetoolfor purpose notintended; for example, don't
use circular saw for cutting tree limbs or logs.
7. DRESS PROPERLY. Don't wear loose clothing orjewelry. They can becaught
in moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors. Wear protective hair covering tocontain 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 bycordor yank it todisconnect from
receptacle. Keep cord from heat, oil, and sharp edges.
IO. SECURE WORK. Use clamps or a vise to hold work. It's safer than using
your hand and
it frees both hands to 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 instructionsfor lubricatingand changing acces-
sories. Inspect toolcords periodicallyand if damaged, have repairedbyautho-
rized service facility. Inspect extension cords periodically and replace if
damaged. Keep handles dry, clean, and free from oil and grease.
13. DISCONNECTTOOLS. When not in use, beforeservicing, and when chang-
ing accessories, such as blades, bits, cutters.

14. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keys and adjusting wrenches are removed from tool before turning
it on.
15. AVOID UNINTENTIONALSTARTING. Don't carry tool with finger onswitch.
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 to use one heavy enough
to carry
the current your product will draw. An undersized cord will cause a drop
inlinevoltage resulting
in loss of power and overheating. Table 1 showsthe
correct size to use depending on cord lengthand nameplate ampere rating.
If
in doubt, use the next heavier gage. The smaller the gage number, the
heavier the cord.

17. OUTDOOR USE EXTENSIONCORDS. When tool is usedoutdoors, use only
extension cords intended for use outdoors and
so marked.
18. STAY ALERT. Watch what you are doing, use common sense. Don't operate
tool when you are tired.
19. 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 itsintended function. Check for alignment of
moving parts, bindingof moving parts, breakageof parts, mounting, andany
other conditions that may affect its operation. A guard or other part that
is damaged should be properly repaired or replaced by an authorized serv-
ice center unless otherwise indicated elsewhere
in this instruction manual.
Have defective switches replaced by authorized service center. Don't use
tool
if switch does not turn it on and off.
20. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded
surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.
21. REPLACEMENT PARTS. When servicing, useonly identicalreplacementparts.
22. POLARIZEDPLUGS. To reduce the risk of electric shock, this equipment has
a polarized plug (one blade is wider than the other). This plug will
fit in a
polarized outlet only one way. If the plug does not fit fully
in the outlet,
reversethe plug.
If it stilldoes notfit, contact aqualifiedelectriciantoinstall
the proper outlet. Do not change the plug
in any way.

VOLTAGE WARNING: Before connecting the tooltoa power source (receptacle,
outlet, etc.) be sure the voltage supplied is the same as that specified on the
nameplate of the tool.
A power source with voltage greater than that specified
for the tool can result
in SERIOUS INJURY tothe user - as well as damage to
the tool.
If in doubt, DO NOT PLUG IN THE TOOL. Using a power source with
voltage less than the nameplate rating is harmful to the motor.
