SAFETY SYMBOLS CONTENTS

Read the ENTIRE manual before set up or use of this product.
1. Keep work area clean. Cluttered areas invite injuries.
2. Observe work area conditions. Do not use machines or power tools in damp
or wet locations. Don’t expose to rain. Keep work area well lighted. Do not
use electrically powered tools in the presence of flammable gases or
liquids. Do not bring combustible materials near the tools.
3. As with any tool, use common sense when operating. Do not wear loose
clothing or jewelry that could become caught by moving parts, causing
injury. Operate tool a safe distance from yourself and others in the work area.
4. Keep children away. Children must never be allowed in the work area. Do
not let them handle machines, tools, hoses or extension cords.
5. Store idle equipment. When not in use, tools must be stored in a dry
location to inhibit rust. Always lock up tools and keep out of reach of
children and other untrained persons. Switch off all unused electrical tools
when stored. Tools are dangerous in the hands of untrained users.
6. Always wear ANSI Z87 approved safety glasses when using tools.
If raising dust, wear a suitable mask.
7. Work Safe. When wearing gloves to operate the tool, make sure that the
gloves do not interfere with operating the Trigger. Test your gloves with the
Trigger before attaching the unit to an air source. Keep your finger away
from the Trigger until you are ready to work. Never start the tool unless
you have a firm grip with both hands and you are positioned at your work
piece or area. Before using the tool, know what is directly underneath the
work area or work piece. The tool can quickly penetrate material. If
working directly on the ground, make sure you are not directly above
shallow cables, lines, or pipes. Keep your limbs and body clear of the tool.
If an accessory or attachment breaks off, the tool tends to surge forward
suddenly. Operate tool a safe distance from yourself and others in the work
area. Make sure the immediate area is clear of other people or animals.
Spectators must stay at a safe distance. Never point the tool or the air hose
(not included) at anyone. Keep proper footing and balance at all times. Do
not reach over or across running machines, hoses, etc.
8. Do not operate any tool if under the influence of alcohol or drugs. Read
warning labels on prescriptions to determine if your judgment or reflexes are
impaired while taking drugs. If there is any doubt, do not operate any tool.
9. Be sure air is in OFF position when connecting tool to air supply.
10. Use only those accessories that are designed for use with tools. For
example, with impact wrenches do not use ordinary sockets. Use impact
sockets for all air tools.
11. Be sure to disconnect tool from air supply before changing accessories,
performing service on tool and when not in use.
12. Follow air source manufacturers’ directions for connection of regulators,
filters, and other accessories to air source. Do not install quick couplers
directly on tool as they put unnecessary strain on the air inlet threads
possibly causing them to wear out prematurely. Instead, install them on a
short length of air hose attached to the tool.
13. Check for damaged parts. Before using any tool, any part that appears
damaged should be carefully checked to determine that it will operate
properly and perform its intended function. Check for alignment and
binding of moving parts; any broken parts or mounting fixtures; and any
other condition that may affect proper operation. Any part that is damaged
should be properly repaired or replaced by a qualified technician.

IMPORTANT SAFETY INFORMATION

Oil tool before each use. 4 to 5 drops of a good grade Air Tool Oil placed in the
air inlet is sufficient. Use proper air pressure and CFM rating listed for this tool.
3
Drain water from hoses and compressor tank. Water in the air supply line will
cause gumming and loss of power. Clean the air filter on the supply line and
flush the tool with gum solvent or a 50/50 mix of air tool oil and kerosene. It
may be necessary to disassemble the tool to properly clean and re-lubricate.
AIR SOURCE
Clean air of correct air pressure is recommended for the power supply for this
tool. A maximum of 90 PSI at the tool is recommended for most air tools of this
class. Check specifications section for recommended pressure. (Depending on
length of air hose and other circumstances, air pressure at compressor may need
to be increased to 100 PSI to ensure 90 PSI at the tool.)
Water in the air hose and compressor tank contributes to reduced performance
and damage of the air tool. Drain the air tank and filters before each use and as
necessary to keep the air supply dry.
AIR RATCHET SAFETY
1. This air ratchet is designed to speed productivity, not for high torque
applications such as head bolts, lug nuts, etc. DO NOT USE THIS RATCHET
UNDER POWER TO BREAK FASTENERS LOOSE. Loosen fasteners by
hand without depressing throttle. Once loose, depress throttle to speed
fasteners in or out. Always perform final torque tightening by hand.
2. Use only impact sockets designed for impact wrenches.
3. This ratchet is rated to 1/2" USS bolt size. Rating will decrease for
U-Bolts, Long Cap Screws, Spring Fasteners and rusted or
corroded fasteners. All of these factors absorb power and reduce
torque capability.
4. Always use approved eye and ear protection when using air powered
tools. If raising dust/debris, wear a suitable mask. Do not wear loose
clothing or jewelry.
5. Always operate tool a safe distance from yourself and others in the work area.
Keep footing and balance at all times.
6. Make sure work piece is secure to allow safe operation of the tool with both
hands. Do not hold the work piece in your hand, lap or against any part of
your body.
7. Make sure trigger is in the “off” position before connecting or disconnecting
the tool from air source. Disconnect tool from air source before changing
accessories, performing service and when not in use.
8. Follow air source manufacturer’s directions for connection of
regulators, filters and other accessories to air source. Do not install
quick couplers directly at tool air inlet. This causes inlet failure due
to excess weight and vibration. Use a whip hose between tool and
quick couplers.
9. DO NOT OVERLOAD! Do not force tool. Match tool capacity to work load
requirement. Use tool within its rated capacity and only for its designated
purpose. Overloading air tools will cause premature wear and/or permanent
damage of internal and external drive parts and will void warranty.
10. Inspect hoses and fittings for wear and damage prior to using tool. Do not
carry or drag tool by the air hose. Keep air hose free from obstruction, twisting
and binding.Carry the pneumatic driving tool at the workplace using only the
handle, and never with the trigger actuated.
Take conditions at the workplace into account. Fasteners can penetrate thin work
pieces or slip off corners and edges of workplaces, and thus put people at risk.
For personal safety, use protective equipment such ad hearing and eye protection.
IMPORTANT: DO NOT direct the adjustable vent hole to the operator or other
person or animals during the use.

2. This ratchet is rated to 1/2" USS bolt size. Rating will decrease for
U-Bolts, Long Cap Screws, Spring Fasteners and rusted or corroded
fasteners. All of these factors absorb power and reduce torque capability.
3. Use the simplest socket to wrench hook-up. Any additional extensions,
u-joints or adaptors will absorb power and reduce torque capability.
4. Forward/Reverse Lever. Select “F” for Forward (Clockwise) or “R” for
Reverse (Counter-clockwise) operation. Do not attempt to change direction
while tool is running.
5. If fastener bogs, slows or binds the tool, use a larger size ratchet tool with a
higher torque rating. Overloading this tool will cause premature wear and/or
permanent damage to internal and external drive parts and will void warranty.

1. You will need to prepare the 1/4" Quick-disconnect Coupler Plug to connect to
the air inlet on the wrench. Wrap the Coupler Plug with pipe thread seal tape
before threading it into the Air Inlet. Connect the a Quick-Disconnect coupler
on a 3/8" ID Air Source Hose to the tool.
Note: If you are not using an automatic oiler system, before operation, add a few
drops of Pneumatic Tool Oil to the airline connection. Add a few drops more after
each hour of continual use.
2. Set the air pressure on your compressor to 90 PSI. Do not exceed the
recommended air pressure of 90 PSI.
3. Check the air connection for leaks. Once you are satisfied there are no leaks,
turn off the air compressor and disconnect the tool.
4. This impact wrench is rated to 9/16 in. USS bolt size. Rating will decrease for U-Bolts,
Long Cap Screws, Spring Fasteners and rusted or corroded fasteners. All of these factors
absorb power and reduce torque capability.
5. Use the simplest socket to wrench hook-up. Any additional extensions, U-joints or
adaptors will absorb power and reduce torque capability.
6. Use only impact sockets designed for impact wrenches.
7. Forward/Reverse Lever. Select “F” for Forward (clockwise) or “R” for Reverse (counter-
clockwise) operation. Do not attempt to change direction while tool is running.
8. If fastener bogs, slows or binds the tool, or if the fastener fails to move after 5 seconds,
use a larger size impact wrench with a higher torque rating. Overloading this tool will
cause premature wear and/or permanent damage to internal and external drive parts and
will void warranty.
9. The air regulator can be used as an air throttle. Turn air regulator knob out (counter-
clockwise) for maximum power.
10.Torque setting: To set the tool to desired torque, select a fastener of known tightness of
the same size, thread pitch and thread condition as those on the job. Turn air regulator to
lowest position. Apply wrench to (turn regulator out) until fastener moves slightly in the
direction it was originally set. The wrench is now set to duplicate the torque applied to
this fastener. Critical torque specifications cannot be met by any wrench in this class.
Use an appropriate torque wrench to obtain a specific torque.

AIR RATCHET OPERATION
IMPACT WRENCH ASSEMBLY & OPERATION

INSUFFICIENT POWER:
Probable Cause Solution
Dirty or clogged air passages Flush and lubricate tool, drain air tank and supply line
Insufficient air supply Increase line pressure, Make sure compressor
matches tool’s air pressure and consumption needs
Air leakage Use teflon tape at all fittings and joints. Check tool for
worn or damaged O-rings & seals.
Worn/damaged wear & tear parts Replace as necessary.
Tool matching Be sure you are using a tool suited for the torque
requirements of the job at hand.
WARNING: Always disconnect the tool from the air source before
examining or changing bits.
1. Select the appropriate chisel/bit. Unscrew the Retainer Spring and insert the
shank of the chisel/bit. Screw the Retainer Spring back onto the Cylinder.
Holding the Air Chisel rmly, pull the chisel/bit hard to make sure it
locked into place.
Note: Before connecting the air supply, make sure you are wearing safety
goggles and a full face mask, ear protection, and steel toe shoes.
WARNING: Any spectators in the immediate area will need eye and
ear protection. Beware of ying chips of wood, concrete, metal, or any
other material being chiseled.
2. Connect the air hose to the Air Inlet and turn on the compressor
(not included).
3. Grip the Air Hammer with both hands rmly and put the chisel/bit tip up
against the workpiece you wish to chip.
4. Gently squeeze the Trigger and move slowly along the workpiece. Do not
push down on the Air Hammer; let it do the work. If it does not do the
intended job to satisfaction, examine your bit to see if it is worn or dull.
WARNING: Always disconnect from the air source before examining or
changing bits.
5. When you are nished, turn off the air supply and then hold the Air Hammer
in a safe direction and Squeeze the trigger to bleed off the remaining air.
Then, disconnect the air hose.
1. Do not put additional pressure on the machine. This will only reduce
sanding efficiency and shorten the tool’s life. We recommend the air
pressure of this grinder at 90 PSI.
2. When using the grinder be careful not to exert excessive force. Too
much force could be hazardous if it caused the cutting tool spindle to
bend or break.
3. The burning of the work piece or excessive speed reduction indicates
too much force being applied. Changing to a free cutting tool may be
better for the desired rate of speed and stock removal.
4. Avoid hazardous conditions by making sure there is sufficient gripping
force on the spindle of the cutting tool by placing the spindle at least
7/16" inside the collet.
5. Lubricate the air motor with a good grade of air tool oil and drain the
tank daily. Grit or gum deposits in the tool may cut power and may be
corrected by cleaning the air strainer and flushing out the tool with
gum solvent oil.
