SAFETY PRECAUTIONS
WARNING: READ ALL INSTRUCTIONS. FAILURE TO FOLLOW ALL
INSTRUCTIONS LISTED BELOW MAY RESULT IN ELECTRIC SHOCK, FIRE AND
/OR SERIOUS INJURY. THE TERM” POWER TOOL” IN ALL WARNINGS
REFERS TO YOUR CIR220 IMPACT WRENCH.
WORK AREA
a. Keep the work area clean and well lit. Cluttered and dark areas invite
accidents.
b. 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.
c. Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
ELECTRICAL SAFETY
a. Avoid body contact with earthed or grounded surfaces such as pipes,
radiators, ranges or refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
b. Do not expose power tools to rain or wet conditions. Any water entering
power tools will increase the risk of electric shock.
c. When operating a power tool outdoors, use an extension cable suitable
for outdoor use. Use of a cable suitable for outdoor use reduces the risk of
electric shock.
PERSONAL SAFETY
a. 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. A moment
of inattention while operating a power tool may result in personal injury.
b. Use safety equipment. Always wear eye protection. Safety equipment
such as a dust mask, non-skid shoes or hearing protection used for
appropriate conditions will reduce personal injuries.
c. Avoid accidental starting. Ensure the switch is in the off position before
plugging the machine in to the power supply.
d. Do not over-reach. Keep your proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.

Parts & Service: 020 8988 7400/E-mail:Part[email protected] or [email protected]
e. Dress properly. Do not wear loose clothing or jewellery. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewelleryor
long hair can be caught on moving parts.
POWER TOOL USE AND CARE
a. Do not force the power tool. Use the correct power tool for your
application. The correct power tool will do a better and safer job at the
rate for which it was designed.
b. Do not use the power tool if the trigger does not turn it on and off. Any
power tool that cannot be controlled with the switch is dangerous and
must be repaired.
c. Disconnect the battery before making any adjustments, changing
accessories, or storing power tools. Such preventive measures reduce the
risk of starting the power tool accidentally.
d. Store idle tools out of the reach of children and do not allow persons
unfamiliar with these instructions to operate the power tool. Power tools
are dangerous in the hands of untrained users.
e. Maintain power tools. Check for misalignment or binding of moving parts,
broken parts, or any condition that may affect the power tools operation.
If damaged, have the power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
f. Use the power tool and accessories in accordance with these instructions
and in the manner intended for the particular type of power tool, taking
into account the working conditions and the work to be performed. Use of
the power tool for operations different from intended could result in a
hazardous situation.
BATTERY TOOL USE AND CARE
a. Recharge only with the charger specified by the manufacturer. A charger
that is suitable for one type of battery pack may create a risk of fire when
used with another battery pack.
b. Use power tools only with specifically designed battery packs. Use of any
other battery pack may create a risk of fire when used with another
battery pack.
c. When the battery pack is not in use, keep it away from other metal
objects, like paper clips, coins, keys, nails, screws or other small metal
objects that can make a connection from one terminal to another.
Shorting the battery terminals together may cause burns or a fire.
d. Under abusive conditions, liquid may be ejected from the battery: avoid
contact. If contact accidentally occurs, flush with water. If liquid contacts
the eyes additionally seek medical help. Liquid ejected from the battery
may cause irritation or burns.

IMPACT WRENCH SAFETY INSTRUCTIONS
a. ALWAYS use the impact wrench in the manner and for the functions
described in these instructions.
b. ALWAYS ensure the impact wrench is not moving with the switchbar in the
centre position when changing sockets etc.
c. Use only impact wrench sockets. DO NOT use standard sockets.
d. 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.
e. ALWAYS avoid excessive use of the wrench. When tightening a nut or bolt,
never allow the wrench to impact more than 7 or 8 times - to avoid over
tightening - 3 to 4 impacts is normally sufficient.
SERVICE
a. 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.
Please keep these instructions in a safe place for future reference.

BATTERY CHARGING
The new battery pack will require charging
before use.
1. Squeeze the battery release buttons on
either side of the battery pack and pull
gently down to disengage the battery pack
from the wrench.
2. Insert the battery pack into the charger, as
shown, noting it will only fit one way.
3. 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 placed into the charger and remains illuminated untill the battery
is charged. When the battery is charged, the red light goes out and
the green light illuminates.
• If charging does not take place, ensure all connections are clean
and free of grease etc.
• A new battery pack may initially not accept full charge. This is
common and does not indicate a fault. It can be recharged fully
after it has been discharged approximately five times.
4. The red charging light should remain on for about 1 hour during charging,
thereafter the green light comes back on and the battery cartridge may
be removed and used.
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.
7. For maximum battery life, we recommend that you maintain the battery
in a fully charged state at all times.
• 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.

11
Parts & Service: 020 8988 7400/E-mail:Part[email protected] or [email protected]
• 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
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 13.
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 switchbar selects the forward or reverse direction of rotation. 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 wrench 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. When discharged, recharge the battery pack as on page 10.
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 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 when 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.

Parts & Service: 020 8988 7400/E-mail:Part[email protected] or [email protected]
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 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 only 3 to 4 impacts 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 manufacturers recommendations.
MAINTENANCE
1. Ensure all fixings remain tight to ensure the machine is in safe working
condition.
2. Check the battery charger power cable to ensure it is free from cracks,
bare wires etc.
3. 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.
• 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.
• Your Clarke impact wrench has been designed to give long and trouble
free service. If, however, having followed the instructions in this booklet
carefully, you encounter problems, take the unit to your local Clarke
dealer.
STORAGE
• Make sure that the machine is stored in a clean, dry place, out of reach of
children when not in use.
• Always store the machine and its charger in the case supplied.
