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

Keep work area clean and well lit. Cluttered or dark

areas invite accidents.

Do n o t o p e r a te p o w e r to ol s in ex p l o s i v e

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

may ignite the dust or fumes.

Keep children and bystanders away while operating a

power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

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.

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.

Do not expose power tools to rain or wet conditions.

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

Do not abuse the cord. Never use the cord for carrying,

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.

When operating a power tool outdoors, use an

extension cord suitable for outdoor use. Use of a

cord suitable for outdoor use reduces the risk of electric shock.

PERSONAL SAFETY

Stay alert, watc h 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.

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.

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.

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.

Do not overreach. Keep proper footing and balance

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

in unexpected situations.

Dress properly. Do not wear loose clothing or jewelry.

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

in moving parts.

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.

Do not wear loose clothing or jewelry. Contain long

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

into air vents.

Do not use on a ladder or unstable support. Stable

footing on a solid surface enables better control of the power 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.

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.

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.

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.

Maintain power tools. Check for misalignment or

binding 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.

Keep cutting tools sharp and clean. Properly maintained

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

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

different from those intended could result in a hazardous situation.

GENERAL SAFETY RULES

SERVICE

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.

WARNING!

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

SPECIFIC SAFETY RULES

Wear ear protectors with impact drills. Exposure to

noise can cause hearing loss.

Use auxiliary handles supplied with the tool. Loss of

control can cause personal injury.

Hold power tools 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 tool “live” and shock the operator.

Know your power tool. Read operator’s manual

carefully. 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.

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.

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.

Protect your hearing. Wear hearing protection during

extended periods of operation. Following this rule will

reduce the risk of serious personal injury.

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.

When servicing a power tool, use only identical

replacement parts. Fo l low 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.

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.

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.

Inspect for and remove all nails from lumber before

using this power tool. Following this rule will reduce the

risk of serious personal injury.

 If the power supply cord is damaged, it must be replaced

only by the manufacturer or by an authorized service center to avoid risk.

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.
