4. GENERAL SAFETY RULES
WORK AREA
1. Keep the work area clean and well lit. Cluttered and dark areas invite
accidents.
2. Do not operate power tools in explosive atmospheres such as in the
presence of flammable liquids, gasses or dust. Power tools create sparks
which may ignite dust or fumes.
3. Keep children and bystanders away while operating a power tool.
Distractions can cause you to loose control.
ELECTRICAL SAFETY
1. Power tools must match the power outlet. Never modify the plug in any
way. Do not use adaptor plugs with earthed (grounded) power tools.
Correct plugs and outlets will reduce the risk of electric shock.
2. Do not expose power tools to rain or wet conditions. Any water entering
power tools will increase the risk of electric shock.
3. Do not abuse the electrical cable. Never use the cord for pulling or
unplugging the power tool. Keep the cable away from sources of heat, oil,
sharp edges or moving parts. Damaged or tangled cables increase the
risk of electric shock.
4. When operating a power tool outdoors, use an extension cable suitable
for outdoor use. Using the correct cable reduces the risk of electric shock.

4
PERSONAL SAFETY
1. Stay alert, watch what you are doing and use common sense when you
are operating a power tool. Do not operate a power tool when you are
tired, ill or under the influence of alcohol, drugs or medication.
2. Wear personal protective equipment including eye protection. Safety
equipment such as a dust mask, non-skid shoes or hearing protection used
for appropriate conditions will reduce injuries. Use a face or dust mask if
operation is particularly dusty. Wear ear protectors/defenders as the noise
level of this machine can exceed 85dB (A).
3. Do not over-reach. Keep your proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
4. Avoid accidental starting of the machine. Ensure the switch is in the off
position and the locking button disengaged before plugging the machine
in to the power supply. Carrying power tools around with your finger on
the trigger or plugging in power tools that are switched on invites
accidents.
5. Remove any adjusting key or wrench before turning the power tool on. A
tool left attached to a moving part may result in injury.
6. Dress properly. Do not wear loose clothing or jewellery which may get
caught in moving parts. Wear protective hair covering to contain long
hair. For best footing, wear rubber soled footwear. Keep floor clear of oil,
scrap wood, etc.
7 Concentrate on the job in hand, no matter how trivial it may seem. Be
aware that accidents are caused by carelessness due to familiarity.
8. Switch the machine OFF immediately after the task is completed.
5.POWER TOOL USE AND CARE
1. Do not force the machine. Use the correct power tool for your application.
It will do a better and safer job at the rate for which it was designed.
2. Do not use the power tool if the switch does not turn it on and off. Any
power tool that cannot be controlled with the switch is dangerous and
must be repaired.
3. Disconnect the power tool from the power supply before making any
adjustments, changing accessories, or storing the tool. These measures will
reduce the risk of the power tool starting accidently.
4. Store power tools out of the reach of children and do not allow persons
unfamiliar with these instructions to operate the power tool. Power tools
are potentially dangerous in the hands of untrained users.
5. Maintain power tools in top condition. Keep tools/ machines clean for the
best and safest performance. Check for misalignment or binding of
moving parts, broken parts, or any condition that may affect the power

5
tool’s operation. If damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power tools.
6. Use recommended accessories. The use of improper accessories could be
hazardous.
7. Machine cleanliness. Do not allow the ventilation slots in the machine to
become blocked with dust.
8. Check the power tool for damage before using the machine. Any
damaged part should be inspected to ensure that it will operate properly
and perform its intended function. Check for alignment of moving parts,
breakage of parts, mountings, and any other condition that may affect
the machine’s operation. Any damage should be properly repaired or
the part replaced. If in doubt, DO NOT use the machine. Consult your
local dealer.
9. Always allow the machine to come to a complete stop before cswitching
from forward to reverse direction and vice-versa.
SERVICE
1. When necessary, have your power tools serviced or repaired by a
qualified person using identical replacement parts. This will ensure that the
safety of the power tool is maintained.
6. IMPACT WRENCH SAFETY INSTRUCTIONS
1. Use the wrench correctly. Only use the impact wrench in the manner and
for the functions described in these instructions.
2. Changing Sockets. Always disconnect the machine from the power
supply when changing sockets etc. Use only Impact Wrench sockets....DO
NOT use standard sockets.
3. Achieve the correct torque. Always finish tightening wheel nuts with a
torque wrench or suitable spanner to the wheel-nut torque as
recommended by the vehicle manufacturer.
4. 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 sufficient.
5. Care of the mains cable. Keep the mains cable well away from the
machine and ensure an adequate electrical supply is close at hand so
that the operation is not restricted by the length of the cable.
6. Use outdoor extension leads. If working outdoors, 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.
Please keep these instructions in a safe place for future reference.

11.OPERATING INSTRUCTIONS
ALWAYS ENSURE THAT THE MACHINE IS DISCONNECTED FROM
THE POWER SUPPLY BEFORE CHANGING THE SOCKET。
WHEN CHANGING FROM FORWARD TO REVERSE OPERATION OR
VICEVERSA, ALWAYS ENSURE THE MACHINE HAS FULLY STOPPED
BEFORE SWITCHING ON IN THE NEW DIRECTION.
LOOSENING A NUT
1. Remove any wheel trim, before selecting the appropriate socket and
placing firmly on the square drive of the wrench.
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 OR NUTS.
2. With the FORWARD/NEUTRAL/REVERSE switch in the REVERSE (R) 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.
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.
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 (F) 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.

9
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 manufacturer’s recommendations
12.MAINTENANCE
CLEANING
1. Always inspect the tool before use and ensure it is in top condition.
2. Ensure all air vents are clear, (use compressed air to clean the

REPLACING THE CARBON BRUSHES
1. Remove and inspect the carbon
brushes after periods of extended
use.
2. Replace them when they
eventually wear down.
• The brushes should be kept
clean and free to slide up and
down in the holders. Both
brushes should be replaced at

10
the same time as a pair. Only
use identical brushes from your
Clarke dealer.
3. Use a screwdriver to remove the
brush holder covers from the
machine body. Draw out the worn
brushes and insert new ones before
replacing the brush holder caps.
