ALL

INSTRUCTIONS.

KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.

CONSIDER WORK AREA ENVIRONMENT. Don't use power tools in damp

or wet locations. Keep work area well

lit.

Don't expose power tools to rain.

Don't use tool

USE RIGHT TOOL. Don't force small tool or attachment to do thejob of a

heavy-duty tool. Don't use tool for purpose not intended.

DRESS PROPERLY. Don't wear looseclothing 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.

USE SAFETY GLASSES. Also use face or dust mask if cutting operation is

dusty.

DON'T ABUSE CORD. Never carry tool by cord or yank

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

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 instructions for lubricating and changing acces-

sories. Inspecttool cords periodically andif damaged, have repairedby autho-

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

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 adjustingwrenches are removedfrom toolbefore turning

on.

15.

AVOID UNINTENTIONAL STARTING. Don't carry plugged-intool

OUTDOOR USE EXTENSION CORDS. Whentoolisusedoutdoors, useonly

extension cords intended for use outdoors and

marked.

STAY ALERT. Watchwhat youare doing, usecommonsense. Don't operate

tool when

you

are tired.

18.

CHECK DAMAGED PARTS. Before further use of the tool, a guard or other

part that is damaged should be carefully checked to determine that

will

operate properly and performitsintended function. Check for alignment of

moving parts, binding of moving parts, breakage of 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

19.

GUARD AGAINST ELECTRIC SHOCK. Prevent body contact

with

grounded

surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.

20.

REPLACEMENTPARTS. When servicing, useonly identicalreplacementparts.

21.

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

polarized outlet only one way. If the

plug

reverse the

plug.

the proper outlet. Do not change the plug

any way.

VOLTAGE WARNING: Beforeconnectingthetool toa 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 thetool can result

SERIOUS INJURY tothe user

as well as damage to

the tool. If

doubt, DO NOT PLUG

THE TOOL. Using a power source

with

voltage less than the nameplate rating is harmful to the motor.

ADDITIONAL SAFETY RULES

Rags, cloth, cord, string and the like should never be left around the work

Avoidcutting nails. Inspect for and removeall nails from the workpiece before

Handle the blades very carefully.

Be sure the bladeinstallationboltsare securely tightened before operation.

Hold the tool firmly with both hands.

Keep hands away from rotating parts.

Before using the tool on an actual workpiece, let
