IMPORTANT SAFETY RULES
Even when the tool is used as prescribed it is not possible to eliminate all
residual risk factors. The following hazards may arise in connection with the
tool’s construction and design:
1- Damage to lungs if an effective dust mask is not worn.
2- Damage to hearing if effective hearing protection is not worn.
3- Health defects resulting from vibration emission if the power tool is being
used over longer period of time or not adequately managed and properly
maintained.
4- Wear eye protection.
5- Always ensure machine is switched off before connecting to air supply.
6- Disconnect any machine from the air supply before changing blades or
discs, and before servicing any type of machine.

USER MANUAL 5
7- Always keep your air tool clean and lubricated. Daily lubrication is
essential to avoid internal corrosion and possible failure.
8- Do not wear watches, rings bracelets or loose clothing when using air tools.
9- Using only light weight coil hoses from a tool to the wall or compressor
coupling. Do not t quick change couplings onto the machine as vibration
can cause the coupling to fail.
10- Do not overload the machine. Allow the tool to operate at its optimum
speed for maximum efciency.
11- Do not increase the air pressure above the manufacturers recommended
level, as excessive overload can cause the machine casing to split. Also,
this creates excessive wear on moving parts and possible failure.
12- In the interests of safety and possible damage to the machine/operator,
always ensure that the machine has stopped before putting it down after use.
13- Always ensure that the work piece is rmly secured leaving both hands
free to control the machine.
14- Always ensure that the accessories such as blades, discs, sockets,
etc. are designed for use with the machine. Also, correctly and securely
fastened before connecting the machine to the air supply.
COMPATIBLE COMPRESSOR AND AIR TOOL:
Always ensure the use of appropriately matched air tools and compressors.
The compressor should be able to supply a minimal air delivery of 9.5
SCFM (90PSI) to ensure the compressor can run continuously with the
VALU-AIR Air-Powered Impact wrench. Using tools or a combination of
tools that together or separately require air pressure more than that of
which the air compressor can deliver will reduce performance and could
void the compressor.

OPERATING INSTRUCTION
AIR SUPPLY
1- Always use clean, dry, regulated, compressed air at 4 to 7bar (60 to
100PSI).
2- Do not exceed the maximum and minimum pressure. Operating the tool
at the wrong pressure (too low or too high) will cause excessive noise or
rapid wear.
3- It is recommended that a lter-regulator-lubricator be used and be
located as close to the tool as possible.
4- If a lter-regulator-lubricator is not installed, place up to 6 drops of
pneumatic tool oil into the air inlet plug before each use.
5- If a lter-regulator-lubricator is installed, keep the air lter clean. A dirty
lter will reduce the air pressure to the tool, which will cause a reduction in
power, efciency, and general performance.
6- Clean air inlet lter weekly.
7- Line pressure should be increased to compensate for unusually long air
hoses (over 8 meters). The hose diameter should be 3/8” I.D.
8- Do not use oxygen or any other combustible or bottled gas to power this
tool.
9- Do not use this tool in the presence of any ammable liquids or gases.

USER MANUAL 7
LOADING AND OPERATION
ENSURE YOU READ, UNDERSTAND AND APPLY SAFETY
INSTRUCTIONS BEFORE USE.
1- Only use impact sockets which are specically designed for use with an
impact wrench.
2- Connect the wrench to the air hose.
3- Place the socket over the subject nut and depress the trigger to operate
the wrench.
4- For reverse (R) rotation, press the speed control knob on the left side
of the tool; For forward (F) rotation, press the speed control knob on the
right side of the tool; Rotate the speed control knob on the left side of the
tool during reverse rotation to control the speed of the air ow as required.
Rotate the speed control knob on the right side of the tool during forward
rotation to control the speed of the air ow as required.
5- The ow of air may be regulated by adjusting ow valve at the base of
the handle.
6- Do not use Impact wrench accessories other than those that are
specically designed for use with the Air-powered impact wrench. Failure
to comply will result in serious injury or loss of life.
DO NOT use any additional force upon the wrench in order to remove a nut.
DO NOT allow wrench to free run for an extended period of time as this will
shorten its life.
LUBRICATION
An automatic in-line lter-regulator-lubricator is recommended (Fig4) as it
increases tool life and keeps the tool in sustained operation. The in-line
lubricator should be regularly checked and lled with air tool oil. Proper
adjustment of the in-line lubricator is performed by placing a sheet of paper
next to the exhaust ports and holding the throttle open approximately 30
seconds. The lubricator is properly set when a light stain of oil collects on

In the event that it becomes necessary to store the tool for an extended period
of time (overnight, weekend, etc.), it should receive a generous amount
of lubrication at that time. The tool should be run for approximately 30
seconds to ensure oil has been evenly distributed throughout the tool. The
tool should be stored in a clean and dry environment.
- It is most important that the tool be properly lubricated by keeping the
airline lubricator lled and correctly adjusted. Without proper lubrication the
tool will not work properly and parts will wear prematurely.
- Use the proper lubricant in the air line lubricator. The lubricator should
be of low air ow or changing air ow type, and should be kept lled to
the correct level. Use only recommended lubricants, specially made for
pneumatic applications. Substitutes may harm the rubber compounds in
the tools O-rings and other rubber parts.
IMPORTANT!
If a lter/regulator/lubricator is not installed on the air system, air operated
tools should be lubricated at least once a day or after 2 hours work with 2
to 6 drops of oil, depending on the work environment, directly through the
male tting in the tool housing.

MAINTENANCE
Disconnect wrench from air supply before changing accessories, servicing
or performing maintenance. Replace or repair damaged parts. Use genuine
parts only. Non-authorized parts may be dangerous.
1- Lubricate the air wrench daily with a few drops of air tool oil dripped into
the air inlet.
2- DO NOT use worn, or damaged sockets.
3- Loss of power or erratic action may be due to the following:
a) Excessive drain on the air line. Moisture or restriction in the air pipe.
Incorrect size or type of hose connectors. To remedy check the air supply
and follow instructions.
b) Grit or gum deposits in the wrench may also reduce performance. If your
model has an air strainer (located in the area of the air inlet), remove the
strainer and clean it.
4- When not in use, disconnect from air supply, clean wrench and store in
a safe, dry, childproof location.
5- Verify that no part is loose or missing and that no part is stuck or jammed.
6- Check the air supply for correct size and type of hose connectors. To
avoid loss of power or erratic action, ensure that there is no additional drain
on the air line and no moisture or restriction in the air pipe.

TROUBLE SHOOTING
The following form lists the common operating system with problem and
solutions.
If any of the following symptoms appears during your operating, stop using
the tool immediately, or serious personal injury could result. Only
a qualied persons or an authorized service center can perform
repairs or replacement of tool. Disconnect tool from air supply before
attempting repair or adjustment. When replacing O-rings or Cylinder,
lubricate with air tool oil before assembly.
PROBLEMS POSSIBLE CAUSES REMEDIES
Tool runs at
normal speed but
loses under load
- Motor parts worn.
- Cam clutch worn or
sticking due to lack of
lubricant.
- Lubricating clutch housing.
- Check for excess clutch oil. Clutch
cases need only be half full. Overfilling
can cause drag on high-speed clutch
parts, ie. a typical oiled/lubricated
wrench requires 1/2 ounce of oil.
GREASE LUBRICATED: NOTE: Heat
usually indicates insufficient grease in
chamber. Severe operating conditions
may require more frequent lubrication.
Tool runs slowly.
Air flows slightly
from exhaust
- Motor parts jammed
with dirt particles
- Power regulator in
closed position
- Air flow blocked by
dirt.
- Check air inlet filter for blockage.
- Pour air tool lubricating oil into air inlet
as per instructions.
- Operate tool in short bursts quickly
reversing rotation back and forth where
applicable.
- Repeat above as needed.
