Intended Use

• Air driven impact wrench, for use with standard ½" sockets to loosen
and tighten nuts and bolts.
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 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

Fitting the quick connector
Note: This tool is supplied with two different male airline quick connectors:
EQ-4 – commonly used in Europe
EN-6 – mainly used in the UK
EQ-4
Europe
• 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 (3). 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
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

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:
• Bar exposed above trigger = 'F' – forward (clockwise rotation)
• Bar exposed at rear of tool = 'R' – reverse (anticlockwise rotation)
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 to locking ring on to the 1/2" Square
Drive (1)
2. Ensure the locking ring engages and the socket is firmly attached by
trying to pull it off the drive
Note: Firmly pull the socket off the drive to remove.
Operation
Loosening a nut or bolt
1. Place the socket over the nut
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 nut or bolt starts moving, release the trigger 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 ratchet to run in 'idle rotation' for an extended
period of time. This will shorten its life.
WARNING: If the tool cannot loosen the nut, 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 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
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 'Specifications' if the tool stalls wile tightening or the
torque produced is insufficient.
WARNING: Be aware that air tools may hold residual pressure after use.
Always bleed air pressure from the tool after shutting off air supply.
