IMPACT WRENCH SAFETY INSTRUCTIONS
1. Use only impact wrench sockets....DO NOT use standard sockets which
could shatter and cause injury.

avoid 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
not store the battery where the temperature may exceed 40oC (104oF)

BATTERY CHARGING
The battery will have been shipped in a low charge state and will require
charging before use.
1. Press the battery release clip on
the front of the battery pack and
slide the battery pack from the
impact wrench.
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, noting
that it will only fit one way.
• The red light will flash to indicate
the battery is charging.
• When charging is complete
(typically after about 3 hours),
both lights will come on. The
battery pack can be
considered charged and be
removed. 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.
• In the event of both LED indicators flashing rapidly, it can be
assumed that either the battery has become too hot, in which case
it should be left to cool down, or that a battery cell has failed and
the battery should be replaced.
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 onto the
impact wrench until it clips into place.

Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
The battery pack should slide in easily. If it is not to be fitted immediately,
ensure that the metal contacts are protected to avoid the possibility of a short
circuit which would cause battery damage. For maximum battery life, we
recommend that you maintain the battery in a fully charged state.
OPERATION
FITTING A SOCKET
1. Align the chosen socket and
simply push it onto the anvil. Use
only ½” square drive impact
sockets as listed on page 12.
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
selector bar.
• When the selector bar is in the
central position the trigger is
locked.
2. Always check the direction of
rotation before operation.
CAUTION: MAKE SURE THAT THE IMPACT WRENCH IS OFF USING THE
SELECTOR BAR 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.

SPEED SELECTION
1. Three running speeds are
available by moving the rocker
switch shown.
LOOSENING A NUT
1. Fit the appropriate socket to the square drive of the impact wrench.
2. With the FORWARD/REVERSE switchbar in the REVERSE running position,
hold the wrench firmly and pull the trigger. The nut will be impacted
repeatedly until it is loosened.
NOTE: As the battery becomes discharged the power available will
drop. The battery will cut out when a low state of charge is
reached. This is normal and is a design feature to protect the
battery from deep discharge. If this occurs, re-charge the battery
as described on page 8.
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 impact wrench, place it on the nut.
2. With the FORWARD/REVERSE selector bar in the forward running position,
and holding the wrench firmly, pull the trigger.
3. Install each nut in turn until it is ‘nipped’ up only - do not tighten fully. When
all nuts are secure, tighten further but take care to prevent over-tightening.
4. ALWAYS finish tightening with a torque wrench to the manufacturers
recommended torque.
WARNING: ENSURE THAT THE CORRECT SOCKET IS BEING USED FOR THE
NUTS ON YOUR PARTICULAR VEHICLE. AN INCORRECT SOCKET SIZE WILL
DAMAGE THE HEADS OF THE BOLTS/NUTS.

BELT HOOK
The impact wrench is provided with a
belt hook. This can be fitted to either
side of the main housing, adjacent to
the battery and is retained by a
single screw.
MAINTENANCE
All bearings etc, in this wrench are lubricated with a sufficient amount of high
grade lubricant for the machines lifetime under normal operating conditions,
therefore no further lubrication is required.

wires etc.
Avoid using solvents when cleaning plastic parts, most plastics are susceptible
to damage from the various types of commercial solvents. Keep the unit clean
by wiping with a dry cloth. DO NOT use solvents as a cleaning agent.
Your Clarke impact wrench has been designed to give long and trouble free
service. If, however, having followed the instructions in this booklet carefully,
