supply when not in use, before changing
accessories or when making repairs.
• Never direct air at yourself or anyone else.
• Whipping hoses can cause severe injury.

3
• Always check for damaged or loose
hoses and fittings.
12. Workplace Hazards
• The use of the tool can expose the
operator's hands to hazards including
crushing, impacts, cuts and abrasions
and heat. Wear suitable gloves to
protect hands.
• Operators and maintenance personnel
should be physically able to handle the
bulk, weight and power of the tool.
• Hold the tool correctly; operator
should be ready to counteract normal
or sudden movements and have both
hands available.
• Maintain a balanced body position and
secure footing.
• It is recommended to use a suspension
arm/spring balancer whenever
possible.
• The working places shall be kept
ventilated, clean and illuminated.
• It is recommended to use means to
absorb the reaction torque above 4
Nm for straight tools, above 10 Nm for
pistol-grip tools.
• Release the trigger in the case of an
interruption of the energy supply.
• Do not use in confined spaces and
beware of crushing hands between
tool and work piece, especially when
unscrewing
• The Pneumatic tool is not intended
for use in potentially explosive
atmospheres and is not insulated
against electric power.
• Make sure there are no electrical
cables, gas pipes, etc., that can cause
a hazard if damaged by use of the tool
13. Additional Safety Topics
• If the operator experiences symptoms
such as persistent or recurring
discomfort, pain, throbbing, aching,
tingling, numbness, burning sensations
or stiness, these warning signs
should not be ignored. The operator
should tell the employer and consult a
qualified health professional.
• If you experience numbness, tingling,
pain or whitening of the skin in your
fingers or hands, stop using the
Pneumatic tool for threaded fasteners,
tell your employer and consult a
physician.
• Appropriate controls to reduce the risk
may include actions such as damping
materials to prevent work pieces from
“ringing”.
• Exposure to vibration can cause
disabling damage to the nerves and
blood supply of the hands and arms.
• Do not use worn or ill-fitting sockets or
extensions, as this is likely to cause a
substantial increase in vibration.
• Support the weight of the tool in a
stand, tensioner or balancer, if possible.
• Hold the tool with a light but safe grip,
taking account of the required hand
reaction forces, because the risk from
vibration is generally greater when the
grip force is higher
• Use hearing protection in accordance
with employer's instructions and
as required by occupational health
and safety regulations. Unprotected
exposure to high noise levels can cause
permanent, disabling, hearing loss
and other problems, such as tinnitus
(ringing, buzzing, whistling or humming
in the ears).
• Dust and fumes generated when
using Pneumatic tools can cause ill
health (for example, cancer, birth
defects, asthma and/or dermatitis);
risk assessment and implementation of
appropriate controls for these hazards
are essential.
• Use respiratory protection in
accordance with employer's
instructions and as required by
occupational health and safety
regulations.
INSTALLATION
Air Pressure
Always use clean and dry air at 90 PSI
(6.2 bar) to operate the Pneumatic tools
Do not operate Pneumatic tools beyond the
maximum working air pressure of 90 PSI
(6.2 bar).
Air Line
For using pneumatic tools eciently, connect
air hose to the air inlet. Compressed air
has traces of moisture (water droplets)
in it and this moisture may permeate into
the pneumatic tools and cause mechanical
failure, therefore It is strongly recommended
to install an air filter, moisture separator,
regulator and lubricator in the air supply line.
Typical air supply setups are shown in the
following figures.

Air Hose
Before connecting the air hose to pneumatic
tool, thoroughly clean the air hose with the blow
out of compressed air. This will prevent both
moisture and dust contained within the hose from
entering the tool and causing possible rusting and
malfunctioning.
OPERATING INSTRUCTIONS
ON/OFF Operation
The trigger of the pneumatic tools are designed
inside of the grip. These are “plug-and-run” type
devices. The pneumatic tool will stop operating in
a few seconds after relieving the trigger
Speed Control
A speed controller is provided to increase /
decrease the speed output. Turn the regulator to
the position of smaller number for the least speed
output and larger number for highest speed
output.
Direction Rotation
Be sure to check the rotation direction before
operating the tool. The right side indicates
the forward direction of rotation and left side
indicates the reverse direction of rotation.
Forward direction is defined as clockwise
direction and reverse direction is defined as
counter clockwise as seen from the operator's
position.
MAINTENANCE
Lubrication
Every week clean the air inlet area with a cloth
to remove foreign particles so the pump is
free of contamination. Lubricate the tool using
pneumatic oil and grease regularly.
Fastening of Parts
Regularly check if all the connected parts are
fastened securely.
Cleaning
Dusty and oily surface on the handle will erode
the protective grip of the tool, because of the
reaction torque. Cleaning the grip with a dry
cloth is highly recommended before and after
operation.
Storage
Store the tool in dry and clean environment.
If the pneumatic tool will not to be used for a
period of time, the residual moisture inside of
the pneumatic tool can cause rusting. Therefore
before storing, oiling the pneumatic tool at
air inlet with pneumatic oil and operating it
for a short time at regular intervals is strongly
recommended.

TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE CORRECTIVE ACTION
Decreased output. Not enough air pressure and / or air flow. Check for loose connections and make
sure that air supply is providing enough air
flow (CFM) at required pressure (PSI) to
the tool’s air inlet.
Note: Do not exceed maximum air
pressure.
Obstructed trigger. Clean around trigger to ensure free
movement.
Incorrect lubrication or not enough
lubrication.
Lubricate using pneumatic oil and grease
Blocked air inlet Clean air inlet area with a dry cloth.
Air leaking from loose housing. Make sure housing is properly assembled
and tight.
Severe air leakage. (Slight air leakage is
normal, especially on older tools.)
Cross-threaded housing components. Check for incorrect alignment and uneven
gaps. If cross threaded, disassemble and
replace damaged parts before use.
Loose housing. Tighten housing assembly. If housing
cannot tighten properly, internal parts
may be misaligned.
Dirty air inlet. Clean air inlet area with a dry cloth
