• For torque-control and continuous-rotation tools, the air pressure has a safety critical effect on
performance. Therefore, requirements for length and diameter of the hose shall be specified.
• Never carry an air tool by the hose .
Air Impact Wrench Safety
• Hold the tool with a firm grip. Impact wrenches can provide instantaneous high levels of torque
whilst driving fasteners that could easily be transferred to the operator .
• Use the auxiliary handle/s, if provided . Loss of control can cause harm to the operator .
• Always ensure the workpiece is secured . A properly secured workpiece using a vice or other
clamping equipment is held more secure than by hand .
• Always wait until the machine has come to a complete stop before setting the tool down . The tool
insert can jam leading to a loss of control over the power tool .

Product Familiarisation
Intended Use
Compressor-powered impact wrench with a 3/8” square drive output. Butterfly-switch operated
forward and reverse function and torque control dial .
Note:
This device is not a torque wrench . Always torque nuts/bolts with a calibrated torque wrench .
Unpacking Your Tool
• Carefully unpack and inspect your new tool . 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 from the air supply and depressurise before cleaning or
carrying out any maintenance .
Note: Before every use, drip 3 droplets of air tool oil into the Air Inlet (7) to increase tool longevity .
Fitting the quick connector
Note:
This tool is supplied with two different male air line quick connectors:
EQ-4 – commonly used in Europe outside the UK
EN-6 – mainly used in the UK

• Please choose the connector that is compatible with the air line system you are using, and install
as outlined below:
1 . Apply some PTFE tape (not included) to the screw threads of the Quick Connector (8) . This will
help to maintain an air-tight 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 (7)
3 . Using a spanner (not included) screw the Quick Connector into the Air Inlet located at the base of
the handle
4 . Connect to air line, 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

RECOIL HOSE
• 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/power can be adjusted by turning the Torque Control Dial (9): ‘0’ = off, ‘1’ =
minimum, ‘8’ = maximum
Socket installation
WARNING:
Always disconnect the tool from the air supply before attaching or removing sockets .
• Push a suitable socket firmly over the 3/8” Square Drive (1)
Note: Firmly pull the socket off the drive to remove
Operation
WARNING:
ALWAYS wear eye protection, adequate respiratory and hearing protection, as well
as suitable gloves, when working with this tool .
Forward and reverse
• This tool features a forward/reverse function. Select the desired direction by pushing the Butterfly
Switch (4) . The letters ‘F’ and ‘R’ marked on the tool indicate the switch position for forward
and reverse:
• ‘F’ – forward (clockwise rotation)
• ‘R’ – reverse (anticlockwise rotation)
• To stop the tool, release the Butterfly Switch
Note: The terms ‘forward’ and ‘reverse’ refer to right-hand threads .
Loosening a nut or bolt
1 . Adjust the tool’s power setting by turning the Torque Control Dial (9) to an appropriate setting . If
in doubt, work up the power values from the ‘1’ setting
2 . Place the socket over the nut
3. Hold the tool firmly by the handle. Your fingers should wrap around the handle and your thumb
should rest on the Butterfly Switch (4)
4 . Brace the machine with your other hand wrapped around the exposed side of the tool to control
torque reaction
5. Press the Butterfly Switch to operate the tool
6. When the nut or bolt starts moving, release the Butterfly Switch to stop the tool and remove the
socket from the nut or bolt . Remove the nut from the socket if needed
Note:
DO NOT allow the 3/8” Square Drive (1) 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 nut or bolt .
Tightening a nut or bolt
1 . Check the torque setting and ensure the nut or bolt can withstand the torque selected
2 . Tighten the nut or bolt as far as possible by hand
3 . Place the socket over the nut
4. Hold the tool firmly by the handle. Your fingers should wrap around the handle and your thumb
should rest on the Butterfly Switch (4)
5 . Brace the machine with your other hand wrapped around the exposed side of the tool to control
torque reaction
6. Press the Butterfly Switch to operate the tool
7 . When the nut has been tightened, remove the tool and socket
WARNING:
DO NOT over-tighten . You should use a calibrated torque wrench to torque the nut to the
correct value after using the impact wrench .
WARNING:
NEVER increase the air pressure above the maximum operating pressure stated in
