still does not fit, contact a qualified elec-
trician to install a polarized outlet. Do not
change the plug in any way.

 Double insula-

tion 

 eliminates the need for the three wire

grounded power cord and grounded power
supply system.

5.

Avoid body contact with grounded sur-
faces such as pipes, radiators, ranges and
refrigerators.

 There is an increased risk of

electric shock if your body is grounded.

6.

Do not expose power tools to rain or wet
conditions.

 Water entering a power tool will

increase the risk of electric shock.

7.

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.

8.

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

9.

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.

10.

Dress properly. Do not wear loose cloth-
ing 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.

11.

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.

12.

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.

13.

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

 Proper footing and

balance enables better control of the tool in
unexpected situations.

14.

Use safety equipment. Always wear eye
protection.

 Dust mask, non-skid safety

shoes, hard hat, or hearing protection must
be used for appropriate conditions. Ordinary
eye or sun glasses are NOT eye protection.

Tool Use and Care

15.

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.

16.

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.

17.

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.

18.

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.

19.

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

 Tools are

dangerous in the hands of untrained users.

20.

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.

21.

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 ser-
viced before using.

 Many accidents are

caused by poorly maintained tools.
