GENERAL SAFETY RULES

WARNING! Read and understand all instructions.

Failure to follow all instructions listed below, may

result in electric shock, fire and/or serious personal injury

SAVE THIS INSTRUCTIONS

1.1

Work Area

- Keep your work area clean and well lit.

Cluttered benches and dark areas invite accidents.

- Do not operate power tools in explosive atmospheres, such as in the presence of

flammable liquids, gases, or dust.

Power tools create sparks which may ignite the dust or

fumes.

- Keep bystanders, children, and visitors away while operatingapower tool.

Distractions

can cause you to lose control.

1.2

Electrical Safety

- Grounded tools must be plugged into an outlet properly installed and grounded in

accordance with all codes and ordinances. Never remove the grounding prong or modify
the plug in any way. Do not use any plugs. Check withaqualified electrician if you are
in doubt as to whether the outlet is properly grounded.

If the tools should electrically
malfunction or break down, grounding providesalow resistance path to carry electricity away
from the user.

- Avoid body contact with grounded surface ad pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body is grounded.

- Don't expose power tools to rain or wet conditions.

Water enteringapower tool will

increase the risk of electric shock

- Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an

outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged
cords immediately.

Damaged cords increase the risk of electric shock.

- When operatingapower tool outside, use an outdoor extension cord marked W-A or W.
These cords are rated for outdoor use and reduce the risk of electric shock.

1.3

Personal Safety

- Stay alert, watch what you are doing and use common sense when operatingapower
tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication.

A

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

- Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair,

clothing, and gloves away from moving parts.

Loose clothes, jewelry, or long hair can be

caught in moving parts.

- Avoid accidental starting. Be sure switch is off before plugging in.

Carrying tools with

your finger on the switch or plugging in tools may result in personal injury.

- Remove adjusting keys or switches before turning the tool on. A

wrench orakey that is

left attached toarotating part of the tool may result in personal injury.

- Do not overreach. Keep proper footing and balance at all times.

Proper footing and

balance enables better control of the tool in unexpected situations.

- 2 -

- Use safety equipment. Always wear eye protection.

Dust mask, non-skid safety shoes, hard

hat, or hearing protection must be used for appropriate conditions.

1.4

Tool use and Care

- Use clamps or other practical way to secure and support the workplace toastable
platform.

Holding the work by hand or against your body is unstable and may lead to loss of

control.

- Do not force tool. Use the correct tool for your application.

The correct tool will do the

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

- Do not use tool if switch does not turn it on or off.

Any tool that cannot be controlled

with the switch is dangerous and must be repaired.

- Disconnect the plug from the power source before making any adjustments, changing

accessories, or storing the tool.

Such preventive safety

- Store idle tools out of reach of children and other untrained persons.

Tools are

dangerous in the hands of untrained users.

- Maintain tools with care. Keep cutting tools sharp and clean.

Properly maintained tools,

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

- Check for misalignment or binding of moving parts, breakage of parts, and any other

condition that may affect the tools operation. If damaged, have the tool serviced before
using.

Many accidents are caused by poorly maintained tools.

- Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool, may become hazardous when used on another
tool.

1.5

SERVICE

- Tool service must be performed only by qualified personnel.

Service or maintenance

performed by unqualified personnel could result inarisk of injury

- When servicingatool, use only identical replacement parts. Follow instructions in

the Maintenance section of this manual.

Use of unauthorized parts or failure to follow

Maintenance instructions may createarisk of electric shock or injury.

2.

SPECIFIC SAFETY RULES

2.1

Hold tool by insulated gripping surfaces when performing an operation where the

cutting tool may contact hidden wiring or its own cord.

Contact witha"live" wire will

make exposed metal parts of the tool"live" and shock the operatior.

2.2

Never lubricate aerosol oil on to the electrical part.
