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

•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 recommended when working outdoors. Wear

protective hair covering to contain long hair. Air vents often cover

moving parts and should also be avoided.

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

is dusty.

• 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 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.

• REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of

checking to see that keys and adjusting wrenches are removed

from tool before turning it on.

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

servicing, and when changing accessories, such as blades, bits,

cutters.

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

on switch

•STAY ALERT. Watch what you are doing. Use common sense. Do

not operate 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.

• CAUTION: When fastening into walls, floors or wherever live

electrical wires may be encountered, DO NOT TOUCH ANY

METAL PARTS OF THE TOOL! Hold the tool only by insulated

grasping surfaces to prevent electric shock if you drill or drive into a

live wire.

• CAUTION: Remove battery pack before adjusting tool torque

setting.

CAUTION: Some tools with large battery packs will stand upright

on the battery pack but may be easily knocked over. When not in use,

place tool on its side on a stable surface where it will not cause a

tripping or falling hazard.

WARNING: Some dust created by power sanding, sawing, grinding,

drilling, and other construction activities contains chemicals known to

cause cancer, birth defects or other reproductive harm. Some

examples of these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry

products, and

• arsenic and chromium from chemically-treated lumber (CCA).

Your risk from these exposures varies, depending on how often you do

this type of work. To reduce your exposure to these chemicals: work in

a well ventilated area, and work with approved safety equipment, such

as those dust masks that are specially designed to filter out

microscopic particles.

•Avoid prolonged contact with dust from power sanding, sawing,

grinding, drilling, and other construction activities. Wear protective

clothing and wash exposed areas with soap and water. Allowing

dust to get into your mouth, eyes, or lay on the skin may promote

absorption of harmful chemicals.
