Vibration Hazards
Exposure to vibration can cause disabling damage to the nerves and blood supply of the hands
and arms. Not all vibration hazards can be eliminated by tool design or construction, and some
residual risks remain. Check the vibration-emission value (obtained using ISO 28927-3) shown in
the 'Specification' table. Ensure the risk it represents is assessed and managed. If the risk cannot be
managed so that it falls within acceptable limits, then do not use the tool.
Take the following steps to reduce risk of vibration-related injury:
• Wear warm clothing when working in cold conditions. Keep hands warm and dry.
• If numbness, tingling, pain or whitening of the skin of fingers or hands is experienced, stop
using the tool, inform employer (where appropriate) and consult a qualified health professional.
• Operate and maintain the tool as recommended in the instructions to prevent an unnecessary
increase in vibration levels.
• Where appropriate, support the weight of the tool in a stand, tensioner or balancer.
• The risk from vibration is generally greater when the grip force is higher. Hold the tool with a
light but safe grip, taking account of the required hand reaction forces.
• Ensure the tool and accessories are properly mounted and in good repair: improperly mounted
or damaged tools can cause excessive vibration.

Intended Use
½" square air drive impact wrench powered by an air compressor, for use with sockets and
accessories to drive nuts, bolts and other fasteners via a rotary/impact action.
Not intended for commercial use.
The tool must ONLY be used for its intended purpose. Any use other than those mentioned in this
manual will be considered a case of misuse. The operator, and not the manufacturer, shall be liable
for any damage or injury resulting from such cases of misuse. The manufacturer shall not be liable
for any modifications made to the tool, nor for any damage resulting from such modifications.
Unpacking Your Tool
• Carefully unpack and inspect your tool. Fully familiarise yourself with all its features and
functions
• Ensure that all parts of the tool are present and in good condition. If any parts are missing or
damaged, have such parts replaced before attempting to use this tool
Before Use
WARNING: Always disconnect the tool from the air supply before adjustment or maintenance
is carried out.
Fitting the quick connector
Note: This tool is supplied with two different male airline Quick Connectors (3) (Fig. I):
EQ-4 – commonly used in Europe
EN-6 – mainly used in the UK
• Please choose the connector that is compatible with the airline system you are using, and install
as outlined below:
1. Apply some PTFE tape (not included) to the screw threads of the Quick Connector. This will help to
maintain an airtight seal
Note: Apply PTFE tape tightly and in a clockwise direction, so it does not come off when the thread
is screwed into the tool.
2. Remove the protective plug from the air inlet
6
3. Using a spanner (not included) screw the Quick Connector into the air inlet located at the base of
the handle
4. Connect to airline, pressurise carefully and carry out a leak check (e.g. by spraying small amounts
of soapy water on to the outside of the connectors)
• Air lines fitted with matching female Quick Connectors will now be a push fit to the tool
WARNING: Do not attach the tool to a hose and the hose to a compressor with only threaded
connections. Always use Quick Connectors so the tool can be removed from the air supply
connection when needed for safe operation.
WARNING: Never fit a female Quick Connector directly to the leader hose/whip hose or directly
to the tool. The stored pressurised air in the tool, even when detached from the main air supply, can
operate the tool unexpectedly.
Recommended air supply
• This tool should be connected to a clean, dry air supply with inline oiler and water separator
• Do not allow supply pressure to exceed the maximum stated (see 'Specification')
• Ensure that water is drained from air system daily
• Ensure that all parts of the system (hoses, couplers, etc.) are correctly rated for the air pressure
to be used
Setting tool power
• The tool speed can be adjusted by pressing and turning the Air/Torque Control Dial (4):
'1' = minimum, '4' = maximum
Forward and reverse
• This tool features a forward/reverse function. Select the desired direction by pushing the Forward/
Reverse Switch (2). The letters 'F' and 'R' marked on the tool indicate the switch position for
forward and reverse.
Note: The terms 'forward' and 'reverse' refer to right hand threads.
Installing a socket
WARNING: Always disconnect the tool from the air supply before attaching or removing
sockets.
1. Push a suitable socket firmly over the locking ring on to the 1/2" Square Drive (1)
2. Ensure the locking ring engages and the socket is firmly attached.
Note: Firmly pull the socket off the drive to remove.
Operation
Loosening a fastener
1. Engage the socket with the fastener
2. Hold the tool firmly by the handle. Your thumb should wrap around the handle and your fingers
should sit on the Trigger (5)
3. Brace the machine with your other hand on the back of the tool to control torque reaction
4. Press the Forward/Reverse Switch (2) inwards until it protrudes out the back of the housing
5. Press the Trigger to start the tool
6. When the fastener is completely undone, release the Trigger to stop the tool and remove the
socket from the fastener
IMPORTANT: DO NOT allow the tool to run in 'idle rotation' for an extended period of time. This
will shorten its life.
WARNING: If the tool cannot loosen the fastener, DO NOT raise the outlet pressure of the air
compressor. Use a manual spanner instead to loosen the fastener.
WARNING: Be aware that air tools may hold residual pressure after use. Always bleed air
pressure from the tool after shutting off air supply.
Tightening a fastener
WARNING: This device is not a torque wrench. Always torque fasteners with a calibrated
torque wrench.
1. Check the torque setting and ensure the fastener can withstand the torque selected
2. Thread the nut/bolt onto the corresponding threaded part for at least one complete turn. Ensure
the pieces are not cross threaded
3. Engage the socket with the fastener
4. Hold the tool firmly by the handle. Your thumb should wrap around the handle and your fingers
should sit on the Trigger (5)
5. Brace the machine with your other hand on the back of the tool to control torque reaction
6. Press the Forward/Reverse Switch (2) inwards until it protrudes out the front of the housing
7. Press the Trigger to start the tool
8. When the nut has been tightened, remove the tool and socket
