INTRODUCTION

This tool has many features for making its use more pleasant and enjoyable. Safety, performance, and dependability have been given top priority in the design of this product making it easy to maintain and operate.

GENERAL SAFETY RULES

WARNING:

Read all instructions. Failure to follow all

instructions listed below, may result in electric shock, fire and/or serious injury. The term “power tool” in all of the warnings listed below refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

SAVE THESE INSTRUCTIONS WORK AREA SAFETY

n Keep work area clean and well lit. Cluttered or dark

areas invite accidents.

n Do not operate power tools in explosive atmo-

spheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which

may ignite the dust or fumes.

n Keep children and bystanders away while operating a

power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

n Power tool plugs must match the outlet. Never modify

the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and

matching outlets will reduce risk of electric shock.

n Avoid body contact with earthed or grounded surfaces

such as pipes, radiators, ranges and refrigerators.

There is an increased risk of electric shock if your body is earthed or grounded.

n Do not expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of electric shock.

n Do not abuse the cord. Never use the cord for carry-

ing, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges, or moving parts.

Damaged or entangled cords increase the risk of electric shock.

n When operating a power tool outdoors, use an exten-

sion cord suitable for outdoor use. Use of a cord suit-

able for outdoor use reduces the risk of electric shock.

PERSONAL SAFETY

n Stay alert, watch what you are doing and use

common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment

of inattention while operating power tools may result in serious personal injury.

n Use safety equipment. Always wear eye protection.

Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

n Avoid accidental starting. Ensure the switch is in the

off-position before plugging in. Carrying power tools

with your finger on the switch or plugging in power tools that have the switch on invites accidents.

n Remove any adjusting key or wrench before turning

the power tool on. A wrench or a key left attached to

a rotating part of the power tool may result in personal injury.

n Do not overreach. Keep proper footing and balance

at all times. This enables better control of the power tool

in unexpected situations.

n Dress properly. Do not wear loose clothing or jew-

elry. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can

be caught in moving parts.

n If devices are provided for the connection of dust

extraction and collection facilities, ensure these are connected and properly used. Use of these devices can

reduce dust-related hazards.

n Do not wear loose clothing or jewelry. Contain long

hair. Loose clothes, jewelry, or long hair can be drawn

into air vents.

n Do not use on a ladder or unstable support. Stable

footing on a solid surface enables better control of the tool in unexpected situations.

POWER TOOL USE AND CARE

Do not force the power tool. Use the correct power

tool for your application. The correct power tool will

do the job better and safer at the rate for which it was designed.

n Do not use the power tool if the switch does not turn

it on and off. Any power tool that cannot be controlled

with the switch is dangerous and must be repaired.

n Disconnect the plug from the power source and/or

the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce

the risk of starting the power tool accidentally.

n Store idle power tools out of the reach of children and

do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power

tools are dangerous in the hands of untrained users.

n Maintain power tools. Check for misalignment or bind-

ing of moving parts, breakage of parts, and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use.

Many accidents are caused by poorly maintained power tools.

n Keep cutting tools sharp and clean. Properly main-

tained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

n Use the power tool, accessories and tool bits etc., in

accordance with these instructions and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations dif-

ferent from those intended could result in a hazardous situation.

GENERAL SAFETY RULES

SERVICE

n Have your power tool serviced by a qualified repair

person using only identical replacement parts. This will

ensure that the safety of the power tool is maintained.

n When servicing a power tool, use only identical replace-

ment parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to

follow Maintenance instructions may create a risk of shock or injury.

SPECIFIC SAFETY RULES

n Hold power tool by insulated gripping surfaces when

performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a

“live” wire will make exposed metal parts of the cutting tool “live” and shock the operator.

n Know your power tool. Read operator’s manual care-

fully. Learn its applications and limitations, as well as the specific potential hazards related to this power tool. Following this rule will reduce the risk of electric

shock, fire, or serious injury.

n Always wear safety glasses. Everyday eyeglasses

have only impact-resistant lenses; they are NOT safety glasses. Following this rule will reduce the risk

of serious personal injury.

n Protect your lungs. Wear a face or dust mask if the

operation is dusty. Following this rule will reduce the

risk of serious personal injury.

n Protect your hearing. Wear hearing protection during

extended periods of operation. Following this rule will

reduce the risk of serious personal injury.

n Inspect power tool cords periodically and, if damaged,

have repaired at your nearest Authorized Service Center. Constantly stay aware of cord location. Following

this rule will reduce the risk of electric shock or fire.

WARNING!

To reduce risk of injury, user must read instruction manual.

n Check damaged parts. Before further use of the power

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. Following this rule

will reduce the risk of shock, fire, or serious injury.

n 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. A wire gauge size (A.W.G.) of at least 14 is recommended for an extension cord 50 feet or less in length. A cord exceeding 100 feet is not recommended. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord. An

undersized cord will cause a drop in line voltage resulting in loss of power and overheating.

n Inspect for and remove all nails from lumber before

using this power tool. Following this rule will reduce the

risk of serious personal injury.

n Save these instructions. Refer to them frequently and

use them to instruct others who may use this power tool. If you loan someone this power tool, loan them these instructions also.

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. 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.
