FOR YOUR SAFETY ■ ALL TOOLS

Important Safety Instructions

WARNING: When using electric tools, basic safety precautions should

always be followed to reduce risk of fire, electric shock, and personal
injury, including the following:

READ ALL INSTRUCTIONS

Double Insulation

Double insulated tools are constructed throughout with two separate layers
of electrical insulation or one double thickness of insulation between you
and the tool’s electrical system. Tools built with this insulation system are
not intended to be grounded. As a result, your tool is equipped with a two
prong plug which permits you to use extension cords without concern for
maintaining a ground connection.

NOTE: Double insulation does not take the place of normal safety precau

tions when operating this tool. The insulation system is for added protec
tion against injury resulting from a possible electrical insulation failure
within the tool.

CAUTION: WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT

PARTS. Repair or replace damaged cords.

Polarized Plugs

Polarized plugs (one blade is wider than the other) are used on equipment

to reduce the risk of electric shock. When provided, this plug will fit into a

polarized outlet only one way. If the plug does not fit fully into the outlet,
reverse the plug. If it still does not fit, contact a qualified electrician to
install the proper outlet. Do not change the plug in any way.

Safety Instructions For All Tools

KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.
CONSIDER WORK AREA ENVIRONMENT. Don’t expose power tools to rain.

Don’t use power tools in damp or wet locations. Keep work area well lit. Do
not use tool in presence of flammable liquids or gases.

GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded

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

KEEP CHILDREN AWAY. Do not let visitors contact tool or extension cord.

All visitors should be kept away from work area.

STORE IDLE TOOLS. When not in use, tools should be stored in dry, and

high or locked-up place — out of reach of children.

DON’T FORCE TOOL. It will do the job better and safer at the rate for which

it was intended.

USE RIGHT TOOL. Don’t force small tool or attachment to do the job of a

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

DRESS PROPERLY. Do not wear loose clothing or jewelry. They can be

caught in moving parts. Rubber gloves and non-skid footwear are recom
mended when working outdoors. Wear protective hair covering to contain
long hair.

USE SAFETY GLASSES. Also use face or dust mask if operation is dusty.
DON’T ABUSE CORD. Never carry tool by cord or yank it to disconnect from

receptacle. Keep cord from heat, oil, and sharp edges.

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.

DON’T OVERREACH. Keep proper footing and balance at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and

safer performance. Follow instructions for lubricating and changing acces
sories. 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.

• DISCONNECT OR LOCK OFF TOOLS when not in use, before servicing, and

when changing accessories, such as blades, bits, cutters.

• REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see

that keys and adjusting wrenches are removed from tool before turning it on.

• AVOID UNINTENTIONAL STARTING. Don’t carry tool with finger on switch.

Be sure switch is off when plugging in.

• 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 in line
voltage resulting in loss of power and overheating. The following table
shows the 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.

OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only

extension cords intended for use outdoors and so marked.

STAY ALERT. Watch what you are doing. Use common sense. Do not oper

ate tool when you are tired.

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, 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 by an authorized service
center unless otherwise indicated elsewhere in this instruction manual. Have
defective switches replaced by authorized service center. Do not use tool if
switch does not turn it on and off.
