IMPORTANT SAFETY

INFORMATION

General Safety Rules

WARNING Read all safety

warnings and instructions.

Failure to follow the warnings and
instructions may result in injury.

Save all warnings and
instructions for future reference.

1. Work area safety

a. Keep work area clean and well

lit. Cluttered or dark areas invite

accidents.

b. Keep children and bystanders

away while operating.

Distractions can cause you to lose

control.

2. Personal safety

a. Stay alert, watch what you are

doing and use common sense

when operating a tool. Do not

use while you are tired or under

the influence of drugs, alcohol

or medication. A moment of

inattention while operating tools

may result in serious personal

injury.

b. Use personal protective

equipment. Always wear ANSI-

approved 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.

c. Do not overreach. Keep proper

footing and balance at all times.

This enables better control of the
power tool in unexpected situations.

3. Tool use and care

a. Do not force the tool. Use the

correct tool for your application.
The correct tool will do the job
better and safer at the rate for
which it was designed.

b. Maintain tools. Check for

misalignment or binding of
moving parts, breakage of parts
and any other condition that may
affect the tool’s operation. If
damaged, have the tool repaired
before use. Many accidents are

caused by poorly maintained tools.

Safety Warnings

1. Maintain labels and nameplates on
the tool. These carry important safety
information. If unreadable or missing,
contact Harbor Freight Tools for a
replacement.

2. This product is not a toy. Keep it out
of reach of children.

3. The warnings, precautions, and
instructions discussed in this
instruction manual cannot cover all
possible conditions and situations that
may occur. It must be understood
by the operator that common sense
and caution are factors which cannot
be built into this product, but must be
supplied by the operator.
