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

n Keep your work area clean and well lit. Cluttered

benches and dark areas invite accidents. Floor must not
be slippery from wax or dust.

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 tools. Distractions can cause you to lose

control.

n Operate air compressor in an open area at least 18 in.

away from any wall or object that could restrict the
flow of fresh air to ventilation openings.

ELECTRICAL SAFETY

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 grounded.

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

tool 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 Eye protection which conforms to ANSI specifications

and provides protection against flying particles both
from the FRONT and SIDE should ALWAYS be worn
by the operator and others in the work area when
loading, operating, or servicing this tool. Eye protection

is required to guard against flying fasteners and debris,
which could cause severe eye injury.

n The employer and/or user must ensure that proper

eye protection is worn. We recommend a Wide Vision

Safety Mask for use over eyeglasses or standard safety
glasses that provide protection against flying particles
both from the front and side. Always use eye protection
which is marked to comply with ANSI Z87.1.

n Additional safety protection will be required in some

environments. For example, the working area may in-

clude exposure to a noise level which can lead to hearing

damage. The employer and user must ensure that any
necessary hearing protection is provided and used by the
operator and others in the work area. Some environments
will require the use of head protection equipment. When
required, the employer and user must ensure that head
protection marked to comply with ANSI Z89.1 is used.

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 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 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 Do not exceed the pressure rating of any component

in the system.

n Protect material lines and air lines from damage or

puncture. Keep hose and power cord away from sharp

objects, chemical spills, oil, solvents, and wet floors.

n Check hoses for weak or worn condition before each

use, making certain all connections are secure. Do not

use if defect is found. Purchase a new hose or notify an
authorized service center for examination or repair.

n Release all pressures within the system slowly. Dust

and debris may be harmful.

n Store idle tools out of the reach of children and other

untrained persons. Tools are dangerous in the hands of

untrained users.

n Maintain tools with care. Follow maintenance instruc-

tions. Properly maintained tools are easier to control.

n 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
serviced before using. Many accidents are caused by

poorly maintained tools.

n Never point any tool toward yourself or others.

n Keep the exterior of the air compressor dry, clean, and

free from oil and grease. Always use a clean cloth when
cleaning. Never use brake fluids, gasoline, petroleum­based products, or any strong solvents to clean the unit.
Following this rule will reduce the risk of deterioration of
the enclosure plastic.

EXTENSION CORDS

Use only 3-wire extension cords that have 3-prong ground­ing plugs and 3-pole receptacles that accept the tool’s plug.
When using a power tool at a considerable distance from the
power source, use an extension cord heavy enough to carry
the current that the tool will draw. An undersized extension
cord will cause a drop in line voltage, resulting in a loss of
power and causing the motor to overheat. Use the chart
provided below to determine the minimum wire size required
in an extension cord. Only round jacketed cords listed by
Underwriter’s Laboratories (UL) should be used.

NOTE: AWG = American Wire Gauge

When working with the tool outdoors, use an extension cord
that is designed for outside use. This is indicated by the
letters

Before using an extension cord, inspect it for loose or
exposed wires and cut or worn insulation.

“W-A” or “W”

on the cord’s jacket.

WARNING:

Keep the extension cord clear of the working area.
Position the cord so that it will not get caught on
lumber, tools or other obstructions while you are
working with a power tool. Failure to do so can
result in serious personal injury.

SPEED AND WIRING

The no-load speed of this tool is approximately 3,450 rpm.
This speed is not constant and decreases under a load or
with lower voltage. For voltage, the wiring in a shop is as
important as the motor’s horsepower rating. A line intended
only for lights cannot properly carry a power tool motor. Wire
that is heavy enough for a short distance will be too light for
a greater distance. A line that can support one power tool
may not be able to support two or three tools.

GROUNDING INSTRUCTIONS

In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current to
reduce the risk of electric shock. This tool is equipped
with an electric cord having an equipment-grounding
conductor and a grounding plug. The plug must be plugged
into a matching outlet that is properly installed and grounded
in accordance with all local codes and ordinances.

Do not modify the plug provided. If it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding conductor
can result in a risk of electric shock. The conductor with
insulation having an outer surface that is green with or with­out yellow stripes is the equipment-grounding conductor. If
repair or replacement of the electric cord or plug is neces­sary, do not connect the equipment-grounding conductor
to a live terminal.

Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if
in doubt as to whether the tool is properly grounded.

Repair or replace a damaged or worn cord immediately.

This tool is intended for use on a circuit that has an outlet
like the one shown in figure 1. It also has a grounding pin
like the one shown. This product must be grounded.

WARNING:

Check extension cords before each use. If
damaged replace immediately. Never use tool with
a damaged cord since touching the damaged area
could cause electrical shock resulting in serious
injury.

NOTE: Use longer air hoses instead of long extension cords.
Your air compressor will run better and last longer.

ELECTRICAL CONNECTION

This tool is powered by a precision-built electric motor. It
should be connected to a power supply that is 120 volts,
60 Hz, AC only (normal household current). Do not operate
this tool on direct current (DC). A substantial voltage drop
will cause a loss of power and the motor will overheat. If
the product does not operate when plugged into an outlet,
double check the power supply.
