3. Should you wish to replace a detachable fuse carrier, ensure that the correct replacement
is used (as indicated by marking or colour code).
4. Replacement fuse covers can be obtained from your local Clarke dealer or most electrical
stockists.
If in any doubt, consult a qualified electrician. DO NOT attempt any electrical repairs
yourself.
5. CABLE EXTENSION
Always use an approved cable extension suitable for the power rating of this tool (see
specifications), the conductor size should also be at least the same size as that on the
machine, or larger. When using a cable reel, always unwind the cable completely.
6. OPERATING INSTRUCTIONS
ALWAYS ENSURE THAT THE MACHINE IS DISCONNECTED FROM THE POWER SUPPLY
BEFORE CHANGING THE SOCKET.
LOOSENING A NUT
1. Remove any wheel trim, before selecting the appropriate socket and placing firmly on the
square drive of the wrench.
2. Select the appropriate socket and place firmly on the square drive of the wrench. Holding
the wrench firmly in BOTH HANDS, pull the rocker switch at 'L' marked on the casing. The
torque will build up and impact the nut repeatedly until the nut is loosened.
3. With the FORWARD/NEUTRAL/REVERSE switch in the REVERSE position, and holding
the wrench firmly in BOTH HANDS, pull the trigger fully. The nut will be impacted repeatedly
until it is loosened. IMPORTANT! Release the trigger immediately the nut begins to loosen.
4. 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 in the FORWARD position, and holding
the wrench firmly in BOTH HANDS, pull the trigger gently. You can vary the spindle speed by
modulating finger pressure on the trigger.
3. Run each nut up in turn until it is 'nipped' up only - do not tighten - do not fully depress
the trigger. 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 or suitable spanner. 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 manufacturers
recommendations.
7. MAINTENANCE
CLEANING
• Always inspect the tool before use, and ensure it is in top condition.
• Ensure all air vents are clear, (use compressed air to clean the machine if possible).
GENERAL MAINTENANCE
• Ensure all nuts, bolts and screws remain tight to ensure the machine is in safe working
condition.
• Refer to your CLARKE dealer if internal maintenance is required.
• Check the power cable to ensure it is sound and free from cracks, bare wires etc. avoid
using solvents when cleaning plastic parts, most plastics are susceptible to damage from the
