IMPACT WRENCH SAFETY INSTRUCTIONS
1. ALWAYS use the impact wrench in the manner and for the functions
described in these instructions.
2. ALWAYS ensure the machine is not moving with the switchbar in the centre
position when changing sockets etc. Use only Impact Wrench
sockets....DO NOT use standard sockets.
3. ALWAYS finish tightening wheel nuts or engine parts with a torque wrench
or suitable spanner to the correct torque as recommended by the vehicle
manufacturer.
4. ALWAYS avoid excessive use of the wrench. When tightening a nut or bolt,
never allow the wrench to impact more than 8 times - to avoid over
tightening - 3 to 4 impacts is normally sufficient.
5. ALWAYS use outdoor extension leads if working outdoors. Always use an
approved cable extension suitable for the power rating of the battery
charger (see specifications), the conductor size should also be at least the
same size or larger than that on the charger. When using a cable reel,
always unwind the cable completely.
Please keep these instructions in a safe place for future reference.

ELECTRICAL CONNECTIONS
WARNING! Read these electrical safety instructions thoroughly
before connecting the product to the mains supply.
Before switching the product on, make sure that the voltage of your electric-
ity supply is the same as that indicated on the rating plate. This product is
designed to operate on 230VAC 50Hz. Do not connect it to any other power
source.
This product may be fitted with a non-rewireable plug. If it is necessary to
change the fuse in the plug, the fuse cover must be refitted. If the fuse cover
becomes lost or damaged, the plug must not be used until a suitable re-
placement is obtained.
If the plug has to be changed because it is not suitable for your socket, or
due to damage, it should be cut off and a replacement fitted, following the
wiring instructions shown below. The old plug must be disposed of safely, as
insertion into a mains socket could cause an electrical hazard.
WARNING! The wires in the power cable of this product are
coloured in accordance with the following code:
Blue = Neutral Brown = Live
If the colours of the wires in the power cable of this product do not corre-
spond with the terminal markings of your plug, proceed as follows.
• The wire which is coloured Blue must be connected to the terminal which
is marked Nor coloured Black.
• The wire which is coloured Brown must be connected to the terminal
which is marked Lor coloured Red.
Plug must be BS1363/A approved.
Always fit a 13 Amp fuse.

BATTERY CHARGING
1. The new battery pack will require
charging before use.
2. Squeeze the battery release buttons on
either side of the battery pack and pull
gently down to disengage the battery
pack from the wrench.
3. Insert the battery pack into the charger,
as shown, noting it will only fit one way.
4. Plug the charger into a 230v (mains)
power supply and switch ON.
• The green light illuminates to show the
unit is connected to the mains supply.
The red light illuminates when the
battery is charged, and flashes while charging (faster if the battery
is either flat or faulty).
• If charging does not take place, ensure all connections are clean
and free of grease etc.
• If the red charging light will only stay on for a few moments, the
battery pack is likely to be defective and it must be replaced.
• 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.
5. After charging, switch off and unplug the charger from the power supply.
6. Remove the battery pack from the charger and slide it back into the
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.
• Remember to avoid extremes of heat or cold when charging. Avoid
temperatures outside the range of Minimum 4°C /Maximum 50°C. Avoid
placing batteries in direct strong sunlight or other heat source.
NOTE: Ni-Cad batteries as used in Clarke cordless power tools should be
given a full charge when first supplied new. Maximum battery performance
will be achieved after approximately 5 complete charge/discharge cycles.
• The battery should be fully discharged before recharging in order to
achieve its optimum performance. Constant topping up after only a small
amount of charge has been used will, in effect, reduce its capacity.
• Ni-Cad batteries will slowly lose their power whilst in storage. Do not leave
the batteries in this state for any length of time.

OPERATION
CAUTION: ALWAYS BE SURE THAT THE TOOL IS SWITCHED 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.
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 10.
2. Squeeze the trigger to start the wrench. Release the trigger to stop.
3. To run the impact wrench in reverse, push the switch-bar through the drive
unit. The direction of rotation is shown on the end face of the switch-bar.
• The 3-position switch bar controls forward or reverse direction of rotation.
Select the appropriate position ONLY when the machine is STATIONARY. Do
not move the switch-bar when the spindle is moving. When the switch-bar
is in the central position the trigger is locked.
4. Always check the direction of rotation before operation.
5. Turn off the machine as soon as the impact sound is heard.
Note: As the battery becomes discharged, the power available will drop.
Operating the machine at low speed will cause a reduction in torque.
6. After use, recharge the battery pack as on page 9. Avoid leaving your
batteries in a discharged state.
LOOSENING A WHEEL NUT
1. Remove any wheel trim, before selecting the appropriate socket and
placing firmly on 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.
3. Jack up the vehicle according to the vehicles handbook so that the
wheel is clear of the ground, then proceed to fully undo the wheel nuts.
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.

TIGHTENING A NUT
1 Start the nut by hand, ensuring it is not cross threaded, then with the
appropriate socket installed on the wrench, place it on the nut.
2. With the FORWARD/NEUTRAL/REVERSE switch-bar in the clockwise
(FORWARD) 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 for 3 to 4 impacts only to prevent
overtightening.
4. ALWAYS finish tightening with a torque wrench. The weight of the vehicle
will need to be placed on the wheel to prevent it from rotating while the
nuts are tightened. Ensure the final torque applied to the nuts meets the
vehicle manufacturer’s recommendations.
RECHARGING
Recharge the battery pack following each period of use.
1. Check that the red CHARGING light illuminates and remains flashing
during the charging process.
2. If the red CHARGING light goes out almost straight away after repeating
this procedure a couple of times, although the green POWER ON light is lit,
the battery pack should be replaced with a new one.
3. The charging light should remain flashing for about 1 hour, after which, the
battery cartridge may be removed and used.
4. After charging, remove the charger from the power supply.
5. For maximum battery life, we recommend that you maintain the battery
in a fully charged state at all times.
MAINTENANCE
• Ensure all fixings remain tight to ensure the machine is in safe working
condition.
• All bearings etc, in this machine are lubricated with a sufficient amount of
high grade lubricant for the machines lifetime under normal operating
conditions, therefore no further lubrication is required.
• Refer to your CLARKE dealer if internal maintenance is required.
