IMPORTANT SAFETY INSTRUCTIONS
IMPROPER OPERATION OR MAINTENANCE OF THIS PRODUCT COULD RESULT IN SERIOUS INJURY AND
PROPERTY DAMAGE. READ AND UNDERSTAND ALL WARNINGS AND OPERATING INSTRUCTIONS BEFORE
USING THIS EQUIPMENT. WHEN USING AIR TOOLS, BASIC SAFETY PRECAUTIONS SHOULD ALWAYS BE
FOLLOWED TO REDUCE THE RISK OF PERSONAL INJURY.
HAZARD
RISK OF EYE OR HEAD
INJURY
RISK OF FIRE OR EXPLOSION
WHAT COULD HAPPEN
• Air powered equipment and power tools
are capable of propellingmaterials such as
metal chips, saw dust, and other debris at
high speed, which could result in serious
eye injury.
• Compressed air can be hazardous. The air
stream can cause injury to soft tissue
areas such as eyes, ears, etc. Particles or
objects propelled by the stream can cause
injury.
• Tool attachments can become loose or
break and fly apart propelling particles at
the operator and others in the work area.
• Abrasive tools such as sanders and
grinders, rotating tools such as drills,
and impact tools such as wrenches are
capable of generating sparks which
could result in ignition of flammable
materials.
• Exceeding the maximum pressure rating
of tools or accessories could cause an
explosion resulting in serious injury.
HOW TO PREVENT IT
• Always wear ANSI approved Z87.1
safety glasses with side shields.
• Never leave operating tool
unattended. Disconnect air hose
when tool not in use.
• For additional protection use an
approved face shield in addition to
safety glasses.
• Make sure that any attachments are
securely assembled.
• Never operate tools near flammable
substances such as gasoline, naptha,
cleaning solvents, etc.
• Work in a clean, well ventilated area
free of combustible materials.
• Use compressed air regulated to a
maximum pressure at or below the
rated pressure of any attachments.
RISK OF LOSS OF HEARING
• Long term exposure to noise produced
from the operation of air tools can lead
to permanent hearing loss.
2 — ENG D21543
• Always wear ANSI S3.19 hearing
protection.
HAZARD
RISK TO BREATHING
INHALATION HAZARD
WHAT COULD HAPPEN
• Abrasive tools, such as grinders and
sanders generate dust and abrasive
materials which can be harmful to
human lungs and respiratory system.
• Some materials such as adhesives and tar,
contain chemicals whose vapors could
cause serious injury with prolonged
exposure.
HOW TO PREVENT IT
• Always wear MSHA/NIO5H
approved, properly fitting face
mask or respirator when using such
tools.
• Always work in a clean, dry, well
ventilated area.
RISK OF INJURY
• Tools left unattended, or with the air hose
attached can be activated by unauthorized
persons leading to their injury or injury to
others.
• Power tools can throw materials through
out the work area.
• Power tools can become activated by
accident during maintenance or tool
changes.
• Power tools can cause the workpiece to
move upon contact leading to injury.
• Loss of control of the tool can lead to
injury to self or others.
• Poor quality, improper, or damaged tools
such as grinding wheels, chisels, sockets,
drills, etc., can fly apart during operation,
propelling particles throughout the work
area.
• Remove air hose when tool is not in
use and store tool in secure location
away from reach of children.
• Keep work area clean and free of
clutter. Keep children and others away
from work area during operation of
the tool.
• Keep work area well lit.
• Remove air hose to lubricate or add
grinders, sanding discs, drills, etc.
to the tool.
• Never carry the tool by the hose.
• Avoid unitentional starting. Don't carry
hooked-up tool with finger on trigger.
• Repair servicing should be done only
by an authorized service
representative.
• Clamps or other devices to prevent
movement.
• Never operate tool while under the
influence of drugs or alcohol.
• Don't overreach. Keep proper footing
and balance at all times.
• Keep handles dry, clean, and free from
oil and grease.
• Stay alert. Watch what you are doing.
Use common sense. Do not operate
tool when you are tired.
• Always use tool attachments rated
for the speed of the power tool.
• Never use tools which have been
dropped, impacted or damaged by
use.
• Use only impact grade sockets on an
impact wrench.
• Do not apply excessive force to the
tool – let the tool perform the work.
RISK OF ENTANGLEMENT
RISK OF CUT OR BURNS
• Tools which contain moving elements,
or drive other moving tools, such as
grinding wheels, sockets sanding
discs, etc. can become entangled in
clothing, jewelry and other loose
objects, resulting in severe injury.
• Tools which cut, shear, drill, punch, chisel,
etc. are capable of causing serious injury.
3 — ENG
• Never wear loose fitting clothes, or
apparel which contains loose straps
or ties, etc. which could become
entangled in moving parts of the tool.
• Remove any jewelry, watches,
identifications, bracelets, necklaces,
etc. which might become caught by
the tool.
• Keep hands away from moving parts.
Tie up or cover long hair.
• Keep the working part of the tool away
from hands and body.

OPERATING INFORMATION
Lubrication
Air tools require lubrication throughout the life of the tool.
The air motor and bearing uses compressed air to power
the tool. Because moisture in compressed air will rust the
air motor, you must lubricate the motor daily. An inline
oiler is recommended.
To lubricate the air motor manually:
1. Disconnect the tool from the air supply holding it so
the air inlet faces up
2. Hold the trigger down and put one teaspoon of air tool
oil in the air inlet (use SAE #10 weight oil if air tool oil
is not available). Holding the trigger down helps
circulate oil in the motor.
3. Connect the tool to an air source, cover the exhaust
port with a towel and run for a few seconds.
Any excess oil in the motor is immediately
expelled from the exhaust port. Always direct exhaust port away from people or
objects.
Air Supply
Recommended Air Compressor: 3/4 HP tank for intermittent use - 1.5 HP or larger for heavier duty use.
Air hose should be at least 3/8" I.D.
Pipe and fittings between compressor and air hose
should be at least 1/2" nominal size. (5/8 I.D.). Be sure
piping is free of droops and sags where moisture can
accumulate.
*The use of air filters and air line lubricators is
recommended.
Operation
Before each use, drain water out of air compressor tank
and condensation from air lines. After clearing air compressor moisture and lubricating tool, connect tool to an
air hose of recommended size. Check air pressure. This
tool operates at a maximum 90 PSI pressure.
Set torque regulator, see chart, to set the desired setting
to avoid over tightening and possible damage. Forward
and reverse direction are controlled by pushing the
button noted. Depress the trigger to operate tool.
*Failure to lubricate the tool at the air inlet will void your
warranty.
Impact wrench sockets and accessories must be
used with this tool. Do not use hand sockets and
accessories.

OPERATING INFORMATION
Lubrication
Air tools require lubrication throughout the life of the tool.
The air motor and bearing uses compressed air to power
the tool. Because moisture in compressed air will rust the
air motor, you must lubricate the motor daily. An inline oiler
is recommended.
To lubricate the air motor manually:
1. Disconnect the tool from the air supply holding it so
the air inlet faces up
2. Hold the throttle lever down and put one drop of air
tool oil in the air inlet (use SAE #10 weight oil if air
tool oil is not available). Holding the throttle lever
down helps circulate oil in the motor.
3. Connect the tool to an air source, cover the exhaust
port with a towel and run for a few seconds.
ANY EXCESS OIL IN THE MOTOR IS IMMEDIATELY EXPELLED FROM THE EXHAUST
PORT. ALWAYS DIRECT EXHAUST PORT
AWAY FROM PEOPLE OR OBJECTS.
*Failure to lubricate the tool at the air inlet will void
your warranty.
Air Supply
Recommended Air Compressor: 1 HP tank for intermittent
use - 1.5 HP or larger for heavier duty use.
Air hose should be at least 3/8" I.D.

be at least 1/2" nominal size. (5/8 I.D.). Be sure piping is

Operation
Before each use, drain water out of air compressor tank
and condensation from air lines. After clearing air compressor moisture and lubricating tool, connect tool to an air
hose of recommended size. Check air pressure. This tool
operates at a maximum 90 PSI pressure.
The throttle control lever provides instant response when
depressed. The reverse button is located in the ratchet
housing and determines the direction of rotation. When
driving a fastener to the point that the ratchet stalls, further
tightening can be accomplished by operating the air
ratchet in the same manner as a manually operated
ratchet.
Impact wrench sockets and accessories must be
used with this tool. Do not use hand sockets and
accessories.
