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 90psi (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 on the
following pages.
(Fig. 4: Portable Air supply Setup; Fig 5:
Stationary air Supply Setup)
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.
OPERATION
ON/OFF Operation
The trigger (Fig. 1) of the Groz pneumatic tools
are designed either inside or outside of the
grip. These are “plug-and-run” type devices.
The pneumatic tool will stop operating in a few
seconds after relieving the trigger
Power Control
A regulator (Fig. 2) is provided to increase /
decrease the power output. Turn the regulator to
the position of smaller circle /number for the least
power output and larger circle/number for highest
power output.
Rotation Direction
Be sure to check the rotation direction (Fig. 3)
before operating the tool. The "F” indicates the
forward direction of rotation and “R” indicates the
reverse direction of rotation. Forward direction
is defined as clockwise direction seen from the
operator's position.
MAINTENANCE
Lubrication
Every week clean the loader adaptor with a cloth
to remove foreign particles so the pump is free of
contamination.
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 spindle
oil and operating it for a short time at regular
intervals is strongly recommended.
Repairs
Always use Genuine Groz Spare parts for all service
and repair.
Do not modify, tamper or make any unnecessary/
temporary repairs to the pneumatic tools.
All major service of maintenance and repairs
should only be carried out by well-trained
technician or by Groz through one of its own
authorized service representatives.
Please check the free speed of the pneumatic tools
after every repair.

WARNING
1. For multiple hazards, read and understand the
safety instructions before installing, operating,
repairing, maintaining, changing accessories
on, or working near the pneumatic tool. Failure
to do so can result in serious bodily injury.
2. Do not discard the safety instructions; give
them to the operator.
3. Only qualified and trained operators should
install, adjust or use the Pneumatic tool.
4. Do not modify this Pneumatic tool.
Modifications can reduce the eectiveness of
safety measures and increase the risks to the
operator.
5. Do not use the Pneumatic tool if it has been
damaged.
6. Ensure that the socket is securely fixed.
7. Use only lubricants recommended by Groz
authorized sales or service representatives.
8. While using a Pneumatic tool, the operator
should adopt a comfortable posture whilst
maintaining secure footing and avoiding
awkward or o-balanced postures.
9. Projectile Hazards
• Failure of the work piece, of accessories
or even of the inserted socket itself can
generate high-velocity projectiles.
• Always wear impact-resistant eye
protection during the operation of the
Pneumatic tool. The grade of protection
required should be assessed for each use.
• Use only impact wrench rated sockets
(impact sockets) in good condition, as poor
condition or hand sockets and accessories
used with impact wrenches can shatter and
become a projectile.
10. Entanglement Hazards
• Entanglement hazards can result in
choking, scalping and/or lacerations if loose
clothing, personal jewellery, neckwear, hair
or gloves are not kept away from the tool
and accessories.
• Gloves can become entangled with the
rotating drive, causing severed or broken
fingers.
• Rotating drive sockets and drive extensions
can easily entangle rubber-coated or
metal-reinforced gloves.
• Do not wear loose-fitting gloves or gloves
with cut or frayed fingers.
• Never hold the drive, socket or drive
extension.
• Keep hands away from rotating drives.
• Keep the hands away from the sockets.
11. Air Supply and Connection Hazards
• Slips, trips and falls are major causes of
workplace injury.
• Be aware of slippery surfaces caused by
the use of the tool and also of trip hazards
caused by the air line or hydraulic hose.
• Proceed with care in unfamiliar
surroundings. Hidden hazards, such as
electricity or other utility lines, can exist.
• Do not install quick coupler directly to the
tool. Couplers contain an air valve that will
allow the air tool to retain pressure and
inadvertently operate after the air supply is
disconnected.
• Disconnect the Pneumatic tool from
the energy supply before changing the
inserted tool or accessory
• Do not exceed the maximum air pressure
stated on the tool.
• Never carry an air tool by the hose.
• Air under pressure can cause severe injury.
• Always shut o air supply, drain hose of
air pressure and disconnect tool from air
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.
• 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

5
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.
TROUBLESHOOTING
PROBLEM CAUSE SOLUTION
