IMPORTANT
SAFETY INSTRUCTIONS
(For All Tools)
WARNING:
WHEN USING ELECTRICTOOLS, BASICSAFETY
PRECAUTIONSSHOULD ALWAYS BE FOLLOWEDTO 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 torain.
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 be storedindry, and high
or locked-up place
- out of reach of children.
5. DON'T FORCETOOL. It will do thejob better and safer at the 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 use tool for purpose not intended; for example, don't
use circular saw for cutting tree limbs or logs.
7. DRESSPROPERLY. Don't wear loose clothingorjewelry. They can be caught
in moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors. Wear protective hair coveringtocontain 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 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
13

safer performance. Follow instructions for lubricating and changing acces-
sories. Inspecttoolcords periodically and
if damaged, haverepairedby autho-
rized service facility. Inspect extension cords periodically and replace if
damaged. Keep handles dry, clean, and free from oil and grease.
DISCONNECTTOOLS. When not
in use, before servicing, and when chang-
ing accessories, such as blades, bits, cutters.

14. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keysand adjusting wrenches are removed from tool beforeturning
it on.
15. AVOID UNINTENTIONALSTARTING. Don't carry tool withfinger 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
inline voltage resulting in
loss of power and overheating. Table 1 showsthe
correct size to 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.

17. OUTDOOR USE EXTENSIONCORDS. Whentool is usedoutdoors, use only
extension cords intended for use outdoors and
so marked.
18. STAY ALERT. Watchwhat 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 its intended function. Check for alignment of
moving parts, bindingof moving parts, breakageof 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 by an authorized serv-
ice center unless otherwise indicatedelsewhere inthis 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 aqualified electrician toinstali
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.
