IMPACT WRENCH SAFETY INSTRUCTIONS
1. ALWAYS ensure the wrench is not moving with the selector bar in the

accidental starting.
LITHIUM-ION BATTERY USE AND CARE
1. Only use the wrench with the battery pack supplied. Use of any another
battery pack may create a risk of injury and fire.
2. Do not charge the battery when the room temperature is below 10oC. Do

BATTERY CHARGING
The battery will have been shipped in a low charge state and will require charg-
ing before use.
1. Squeeze the battery release clips
on either side of the battery pack
and pull gently down to
disengage the battery pack from
the wrench as in Fig 1.
2. Plug the charger into a 230V
power supply and switch ON.
• The green POWER ON light will
illuminate to show the unit is
connected to the mains supply.
3. Insert the battery pack into the
battery charger, as shown in Fig 2,
noting that it will only fit one way.
• The red light will come on to
indicate the battery is charging.
• When charging is complete
(typically after about 1 hour),
the GREEN charging light comes
on. The battery pack can be
considered charged and be
removed. The charging time will
be dependant upon the initial
state of the battery.
• When charging a new battery
pack it may initially not accept
full charge. This is common & does not indicate a fault. It can be
recharged fully after it has been discharged a couple of times.
• If charging does not take place, ensure all connections are clean.
4. After charging, switch off and unplug the charger from the power supply.
5. Remove the battery pack from the charger and slide it back into the
impact wrench until it clips into place.
The battery pack should slide in easily. If the battery pack is not to be fitted
immediately, ensure that the metal contacts are protected so as to avoid the
possibility of a short circuit which would cause damage. For maximum battery
life, we recommend that you maintain the battery in a fully charged state at
all times.

OPERATION
FITTING A SOCKET
1. Align the chosen socket and
simply push it onto the anvil. Use
only ½” square drive impact
sockets supplied, or as listed on
page 11.
2. Squeeze the trigger to start the
impact wrench. Release the
trigger to stop.
FORWARD/REVERSE SELECTION
1. Select the direction of operation by
pushing the selector bar in the
appropriate direction.
• The direction of rotation is shown on
the end face of the switch-bar.
• When the selector bar is in the central
position the trigger is locked.
2. Always check the direction of rotation
before operation.
LOOSENING A NUT
1. Fit the appropriate socket to the square
drive of the wrench.
2. With the FORWARD/NEUTRAL/REVERSE
switchbar in the REVERSE running position, and holding the wrench firmly in
BOTH HANDS, pull the trigger. The nut will be impacted repeatedly until it is
loosened. IMPORTANT! Release the trigger immediately the nut begins to
loosen.
CAUTION: MAKE SURE THAT THE WRENCH IS FULLY OFF BEFORE
ATTACHING OR REMOVING A SOCKET. ALWAYS TAKE CARE TO USE THE
CORRECT SIZE SOCKET FOR BOLTS AND NUTS. AN INCORRECT SOCKET
WILL CAUSE DAMAGE TO THE BOLT OR NUT.

.
NOTE: As the battery becomes discharged, the power available will
drop.
3. After use, recharge the battery pack as shown on page 8. Avoid leaving
the batteries in a discharged state.
TIGHTENING A NUT
1. Start the nut by hand, ensuring it is not cross threaded, then with the
appropriate socket fitted to the wrench, place it on the nut.
2. With the FORWARD/NEUTRAL/REVERSE switch-bar in the clockwise
(FORWARD ARROW) running position, and holding the wrench firmly in
BOTH HANDS, pull the trigger.
3. Run each nut up in turn until it is ‘nipped’ up only - do not tighten. When all
nuts are nipped up, tighten progressively by pulling the trigger fully and
allowing the action to operate as little as possible to prevent over-
tightening.
4. ALWAYS finish tightening with a torque wrench.
WARNING: ENSURE THAT THE CORRECT SOCKET IS BEING USED FOR THE
NUTS ON YOUR PARTICULAR VEHICLE. AN INCORRECT SOCKET SIZE IS
LIKELY TO DAMAGE THE HEADS OF THE BOLTS/NUTS.
