IMPORTANT SAFETY INSTRUCTIONS
SYMBOLS
In this manual and/or on the machine the following symbols are used:
WARNING –When using tools, basic precautions should always be followed, including the
following:
General
To reduce the risks of electric shock, fire, and injury to persons, read all the
instructions before using the tool.
Work Area
1. Keep the work area clean and well lighted. Cluttered benches and dark areas increase the
risks of electric shock, fire, and injury to persons.
2. Do not operate the tool in explosive atmospheres, such as in the presence of flammable
liquids, gases, or dust. The tool is able to create sparks resulting in the ignition of the dust or
fumes.
3. 3. Keep bystanders, children, and visitors away while operating the tool. Distractions are
able to result in the loss of control of the tool.
Personal Safety
1. Stay alert. Watch what you are doing and use common sense when operating the tool. Do
not use the tool while tired or under the influence of drugs, alcohol, or medication.Amoment
of inattention while operating the tool increases the risk of injury to persons.
Denotes risk of personal injury, loss of life or damage to the tool in
case of non-observance of the instructions in this manual.
Wear hearing protection.
Wear safety goggles.
Contact with or inhalation of dust coming free during use (e.g.
lead-painted surfaces, wood and metal) can endanger your health
and the health of bystanders. Always wear appropriate protective
equipment, such as a dust mask. Always use proper dust
extraction during use.
Wear gloves.

2. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep hair, clothing,
and gloves away from moving parts. Loose clothes, jewelry, or long hair increases the risk of
injury to persons as a result of being caught in moving parts.
3. Avoid unintentional starting. Be sure the switch is off before connecting to the air supply. Do
not carry the tool with your finger on the switch or connect the tool to the air supply with the
switch on.
4. Remove adjusting keys and wrenches before turning the tool on. A wrench or a key that is
left attached to a rotating part of the tool increases the risk of personal injury.
5. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance
enables better control of the tool in unexpected situations.
6. Use safety equipment. A dust mask, non-skid safety shoes and a hard hat must be used for
the applicable conditions. Wear heavy-duty work gloves during use.
7. Always wear eye protection. Wear ANSI-approved safety goggles.
8. Always wear hearing protection when using the tool. Prolonged exposure to high intensity
noise is able to cause hearing loss.
TOOL USE AND CARE
1. Use clamps or another practical way to secure and support the workpiece to a stable
platform. Holding the work by hand or against the body is unstable and is able to lead to loss
of control.
2. Do not force the tool. Use the correct tool for the application. The correct tool will do the job
better and safer at the rate for which the tool is designed.
3. Do not use the tool if the switch does not turn the tool on or off. Any tool that cannot be
controlled with the switch is dangerous and must be repaired.
4. Disconnect the tool from the air source before making any adjustments, changing
accessories, or storing the tool. Such preventive safety measures reduce the risk of starting
the tool unintentionally. Turn off and detach the air supply, safely discharge any residual air
pressure, and release the throttle and/or turn the switch to its off position before leaving the
work area.
5. Store the tool when it is idle out of reach of children and other untrained persons. A tool is
dangerous in the hands of untrained users.
6. Maintain the tool with care. Keep a cutting tool sharp and clean. A properly maintained tool,
with sharp cutting edges reduces the risk of binding and is easier to control.
7. Check for misalignment or binding of moving parts, breakage of parts, and any other
condition that affects the tool's operation. If damaged, have the tool serviced before using.
Many accidents are caused by poorly maintained tools. There is a risk of bursting if the tool is
damaged.
8. Use only accessories that are identified by the manufacturer for the specific tool model. Use
of an accessory not intended for use with the specific tool model, increases the risk of injury
to persons.

OPERATING INSTRUCTIONS
Figure .1 –Airline Oiler
Use
Step 1: Set the compressor’s pressure regulator to a maximum of 90 PSI. 90 PSI is
satisfactory without harming this tool.
Step 2: You will need to purchase a union fitting (sold separately) before you can connect the
Impact Wrench to your air compressor. You may also wish to purchase an Air Coupler
as this allows quick-coupling action when using multiple tools with one compressor.
Step 3: Determine the socket size necessary for the job you need to do. Attach the appropriate
1/2" drive socket to the Impact Wrench as shown in Figure 2.
Figure 2 —Attaching the Air Coupler and Socket
Step 4: Connect the Impact Wrench to the air compressor’s hose. If leaking is detected,
disconnect the air hose and repair before use.

6
Step 5: Select the power setting for Loosening by adjusting the AIR REGULATOR (#36)
located on the bottom of the Impact Wrench as shown in Figure 3. When the Air
Regulator is completely screwed in it is at it’s lowest setting. Air pressure increases as
you loosen the Air Regulator.
CAUTION: Use the Setting Appropriate for the Job. Do Not Set the Power Setting Higher Than
Needed. Damage to Parts Could Result.
Figure .3–Adjusting the Reverse Power Setting
Step 6: Select the direction of the Wrench (forward or reverse) by pushing the REVERSE
VALVE (#42) located on the handle of the Impact Wrench as shown in Figure 4.
Figure 4 —Selecting Reverse Direction, Pressing Trigger
Step 7: Press the TRIGGER (#31) to test the Impact Wrench. The Impact Wrench should spin
freely as shown if Figure 4.

Loosening
Step 1: Verify that the power level is correct for your needs and that the REVERSE VALVE
(#42) has been shifted (pressed) completely to the right. If not, refer to Steps 5 through
9 under Use before proceeding.
Step 2: Place your work in as clear a location as possible. Make sure the air hose will reach as
far as needed without stressing any connections.
Step 3: With the correct socket attached to the Impact Wrench, slide the socket over the nut or
bolt.
Step 4: Grip the Impact Wrench with both hands, especially with higher power settings. Make
sure you are in a stable position and spread your feet shoulder-width apart.
Step 5: Press the TRIGGER (#31) to loosen the bolt.
Step 6: If the bolt will not loosen, and you are on a low power setting for Loosening, try
increasing the power setting and attempt again.
Step 7: If the bolt will not loosen with the Impact Wrench on a higher power setting, do not
repeat attempts to loosen. You may snap the bolt or strip the threads of the stud or nut.
Try another method to loosen the bolt or nut.
WARNING ！ The Impact Wrench May Kick Back During Operation. If This Happens, Release
the TRIGGER IMMEDIATELY!
Tightening
Step 1: Verify that the power level is correct for your needs and that the REVERSE VALVE
(#42) has been shifted (pressed) completely to the left. If not, refer to Steps 5 through 9
under Use before proceeding.
Step 2: Place your work in as clear a location as possible. Make sure the air hose will reach as
far as needed without stressing any connections.
Step 3: Thread the nut or bolt on as far as possible by hand. This is to prevent cross-threading.
Step 4: If you have torque specs for the nut or bolt you are working on, refer to them. If a low
torque setting is given, it is recommended that you use a socket wrench or a manual
torque wrench to tighten as the Impact Wrench may provide too much torque, even in
the lowest power setting.
Step 5: Place the socket onto the nut or bolt.
Step 6: Grip the Impact Wrench with both hands, especially with higher power settings. Make
sure you are in a stable position and spread your feet shoulder-width apart.
Step 7: Press the TRIGGER to tighten the bolt.
Step 8: When the bolt is tight, release the TRIGGER. DO NOT OVER TIGHTEN!
MAINTENANCE
There are no user-serviceable parts in your Impact Wrench. Attempts to repair or make
adjustments on your tool are prohibited and will VOID your warranty.
Wipe down your tool after every use and store it in a drawer or other safe place
