Safety Information
WORK AREA SAFETY
1. Keep your work area clean and well lit. Ensure floors are not
slippery from wax or dust.
2. 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. Keep
bystanders, children, and visitors away while operating tools.
Distractions can cause you to lose control.
3. Always disconnect the air supply and power supply before
making adjustments, servicing a tool, changing an accessory or
when a tool is not in use.
4. For further information on the safe use of air tools, we advise
you to obtain a copy of CAGI B186.1-2009 from
Husky Air Tools
851 Jupiter Park Lane
Jupiter, Florida 33458
(877) 260-1630.
PERSONAL SAFETY
1. Use safety equipment. Always wear eye protection with side
shields when operating power tools. Dust mask, nonskid
safety shoes, hard hat, or hearing protection must be used for
appropriate conditions.
2. Stay alert when operating a power tool. Do not use the tool while
tired or under the influence of drugs, alcohol, or medication.
3. 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.
4. Keep proper footing and balance at all times. Proper footing
and balance enables better control of the tool in unexpected
situations.
5. Do not use on a ladder or unstable support.

CAUTION: This product contains chemicals known to
the State of California to cause cancer and birth defects or
other reproductive harm. Wash hands after handling.
WARNING: Some dust created by power sanding, sawing,
grinding, drilling and other construction activities contains
chemicals known to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals are:
Lead from lead based paint, crystalline silica from bricks
and cement and other masonry products, arsenic and
chromium from chemically-treated lumber.
Your risk from those exposures varies, depending on how
often you do this type of work. To reduce your exposure to
these chemicals: work in a well-ventilated area, and work
with approved safety equipment, such as dust masks that
are specifically designed to filter out microscopic particles.
Safety Information (continued)
AIR COMPRESSOR AND AIR TOOL SAFETY
1. Risk of Bursting. Do not adjust regulator to result in output
pressure greater than marked maximum pressure of this air tool.
WARNING: Do not use at pressure greater than the rated
maximum pressure of this air tool.
2. Ensure the hose is free of obstructions or snags. Entangled or
snarled hoses can cause loss of balance or footing and may
become damaged.
WARNING: Do not attempt to modify this tool or create
accessories not recommended for use with this tool. Any
such alteration or modification is misuse and could result in
a hazardous condition leading to possible serious personal
injury.
3. Never leave a tool unattended with the air hose attached.
4. Do not operate this tool if it does not contain a legible warning
label.
WARNING: Operating any power tool can result in foreign
objects being thrown into your eyes, which can result in
severe eye damage. Before beginning operation, always
wear safety goggles, safety glasses with side shields, or
a full face shield when needed. Always use eye protection
marked to comply with ANSI Z87.1
5. Do not continue to use a tool or hose that leaks air or does not
function properly.
6. Never direct a jet of compressed air toward people or animals.
7. Protect your lungs. Wear a face or dust mask if the operation is
dusty.
WARNING: Avoid Prolonged Exposure to Vibration
Pneumatic tools can vibrate during use. Prolonged exposure
to vibration or very repetitive hand and arm movements,
can cause injury. Stop using any tool if discomfort, tingling
feeling or pain occurs. You should consult your physician
before resuming use of the tool.
WARNING: Hearing Protection is Recommended
Hearing protection should be used when the noise level
exposure equals or exceeds an 8 hour time-weighted
average sound level of 85dBA.

Installation
1 Cleaning the air hose
□□ A 3/8" air hose is required, with a maximum length of 25 ft.
□□ Clean the air hose of accumulated dust and moisture
before connecting it to the air supply.
NOTE: If a longer air hose is required, connect a 1/2" air
hose to the 3/8" air hose to ensure the ratchet wrench has
the necessary air supply.
2 Connecting to the air supply
Recommended Air Line Set-Up
Part
□□ Always use clean dry air. Excessive moisture and dirt will
greatly reduce the life of any air motor. We recommend the
installation of an in-line filter-regulator-lubricator as close
to the tool as possible.
□□ Ensure all hoses and fittings are the correct size and
secured tightly.

□□ This 3/8 inch. Air Ratchet Wrench is designed to operated
on 90 PSIG. Low pressure (below 90 PSIG) will reduce the
power output. Higher pressure (over 90 PSIG) raises the
tool performance beyond its rated capacity and could result
in serious damage to the tool and/ or operator.
Installing and removing the sockets
WARNING: Disconnect tool from air supply before servicing
or changing accessories.
To install the sockets
□□
Disconnect the tool from the air source
□□
Select the suitable and desirable socket size
□□
Press fit the anvil into the socket
To remove the impact socket
□□
Disconnect the tool from the air source;
□□
Use the hand or suitable tool to remove the socket;

□□ This tools features the reverse switch to change the
output torque direction to tighten( assemble) or loose
(disassemble) the bolt or fastener. Control the output torque
direction by turning the reverse switch to the F (Forward)
or R (Reverse) position to change the direction.
Tightening or loosening the bolt or
fastener
□□ Fit the socket in.
□□ Hold the ratchet wrench with one hand.
□□ Use the tool to tighten or loose the bolt of fastener
Maintenance
Ensure the air line is shut-off and drained of air before removing this tool for service or changing
sockets. This will prevent the tool from operating if the throttle is accidentally engaged.
LUBRICATION
□□ An in-line filter-regulator-lubricator is recommended as it increases tool life and keeps the tool in
sustained operation.
□□ Regularly check and fill the in-line lubricator with air tool oil. Avoid using excessive amounts of oil.
□□ Adjust the in-line lubricator by placing a sheet of paper next to the tool’s exhaust ports and holding the throttle open approximately 30
seconds. The lubricator is properly set when a light stain of oil collects on the paper.
□□ If it is necessary to store the tool for an extended period of time (overnight, weekend, etc), generously lubricate the tool through the air
inlet. Run the tool for approximately 30 seconds to ensure the oil is evenly distributed throughout the tool. Store the tool in a clean and
dry environment.
□□ Recommended lubricants: Air tool oil or any other high grade turbine oil containing moisture absorbent, rust inhibitors, metal wetting
agents, and an EP (extreme pressure) additive.
Troubleshooting
Problem
Possible Cause
Solution
The tool runs slowly or will not
operate.
There is grit or gum in the tool.
Flush the tool with air tool oil or gum solvent.
The tool is out of oil.
Lubricate the tool according to the lubrication
instructions in this manual.
The air pressure is low.
□□ Adjust the regulator on the tool to the
maximum setting.
□□ Adjust the compressor regulator to the tool’s
maximum setting of 90 psi.
The air hose leaks.
Tighten and seal the hose fittings with pipe thread
tape if leaks are found.
The air pressure drops.
□□ Ensure the hose is the proper size. Long
hoses or tools using large volumes of air may
require a hose with an I.D. of ½" or larger
depending on the total length of the hose.
□□ Do not use a multiple number of hoses
connected together with a quick connect
fitting. This causes additional pressure drops
and reduces the tool power. Directly connect
the hoses together.
There is moisture blowing out
of the tool’s exhaust.
There is a worn rotor blade in the motor.
Replace the rotor blade.
There is a worn ball bearing in the motor.
Remove and inspect the bearing for rust, dirt, and
grit. Replace or clean and grease the bearing with
bearing grease.
There is water in the tank.
Drain the tank. (See the air compressor manual
for instructions.) Lubricate the tool and run it until
water is not evident. Lubricate the tool again and
run for 1-2 seconds.
