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 THESE INSTRUCTIONS
WORK AREA

�     Keep  your  work  area  clean  and  well  lit. 

Cluttered 

benches and dark areas invite accidents.

n

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.

n

Keep bystanders, children, and visitors away while 

operating a power tool. 

Distractions can cause you to 

lose control.

ELECTRICAL SAFETY

n

Double insulated tools are equipped with a polarized 

plug (one blade is wider than the other). This plug will 

fit in a polarized outlet only one way. If the plug does 

not  fit  fully  in  the  outlet,  reverse  the  plug.  If  it  still 

does not fit, contact a qualified electrician to install 

a polarized outlet. Do not change the plug in any way. 

Double insulation 

 eliminates the need for the three-

wire grounded power cord and grounded power supply 

system.

n

Avoid body contact with grounded surfaces such as 

pipes, radiators, ranges, and refrigerators. 

There is an 

increased risk of electric shock if your body is ground-

ed.

n

Don’t 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 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.

n

When operating a power 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.  

PERSONAL SAFETY

n

Stay alert, watch what you are doing and use common 

sense when operating a power tool. Do not use tool 

while 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

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.

n

Avoid  accidental  starting.  Be  sure  switch  is  off 

before plugging in.

 Carrying tools with your finger on the 

switch or plugging in tools that have the switch on invites 

accidents.

n

Remove adjusting keys or wrenches before turning 

the tool on.

 A wrench or a key that is left attached to a 

rotating part of the tool may result in personal injury.

n

Do not overreach. Keep proper footing and balance 

at all times.

 Proper footing and balance enables better 

control of the tool in unexpected situations. 

n

Use safety equipment. Always wear eye protection.

 

Dust mask, nonskid safety shoes, hard hat, or hearing 

protection must be used for appropriate conditions.

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.

TOOL USE AND CARE

n

Use  clamps  or  other  practical  way  to  secure  and 

support the workpiece to a stable platform. 

Holding 

the work by hand or against your body is unstable and 

may lead to loss of control.

n

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.

n

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.

n

Disconnect the plug from the power source before 

making any adjustments, changing accessories, or 

storing the tool. 

Such preventive safety measures reduce 

the risk of starting the tool accidentally.

n

Store  idle  tools  out  of  reach  of  children  and  other 

untrained persons.

 Tools are dangerous in the hands 

of untrained users.

n

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.

n

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.

n

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.

n

 

Keep the tool and its handle dry, clean and free from 

oil and grease. 

Always use a clean cloth when clean-

ing. Never use brake fluids, gasoline, petroleum-based 

products,  or  any  strong  solvents  to  clean  your  tool. 

Following this rule will reduce the risk of loss of control 

and deterioration of the enclosure plastic.
