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 wrench is not moving and disconnected from the air
supply 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 impact 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 ensure that the socket is correctly installed before switching on.
6. Always only use sockets which are specified for impact wrench use.
7. Due to the possible presence of asbestos dust from brake linings, always
wear suitable respiratory protection.
8. Never carry the impact wrench by the air supply hose.
9. Always disconnect from the air supply when changing bits or when the
wrench is not required for immediate use in order to avoid accidental
starting.

COMPRESSED AIR REQUIREMENTS
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF
COMPRESSORS AND COMPRESSED AIR SUPPLY.
• Use only clean, dry, regulated compressed air as a power source.
• Air compressors used with the tool must comply with the appropriate
European Community Safety Directives.
• A build-up of moisture or oil in the air compressor will accelerate
wear and corrosion in the tool. Ensure any moisture is drained from
the compressor daily and the inlet filter is kept clean.
• If an unusually long air hose is required, (over 8 metres), the line
pressure or the hose inside diameter may need to be increased.
• The air hose must be rated at least 150% of the maximum operating
pressure of the tool.
• A typical air line layout is shown above. If an automatic in-line filter/
regulator is used, it will keep the tool in good condition, but should
be regularly checked and topped up with oil. clarke airline oil should
be used, and the lubricator adjusted to approx 2 drops per minute.
• For optimum performance it is recommended that a 3/8” ID hose is
used.
• Never exceed the maximum operating pressure for the tool. It is
recommended that air pressure to this tool does not exceed 90 psi
at the tool when running. Higher pressures and dirty air will shorten
the life of the tool due to faster wear and is a possible safety hazard.

BEFORE USE
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF AIR
COMPRESSORS AND COMPRESSED AIR SUPPLY.
NOTE: Ensure the compressor is turned off.
1. If required, connect an in-line mini oiler to the tool.
• A mini oiler helps to prolong the life of the impact wrench.
2. If a mini-oiler is not being used, run
a few drops of oil through the tool
before use. It can be entered
through the airline connector or
via the hose at the nearest
connection to the air supply.
3. Connect a suitable hose as shown.
4. Connect the other end of the hose
to the compressor.
5. Turn on the air supply and check
for air leaks. Rectify any found before proceeding.
• PTFE tape may be useful for sealing threaded connections.
Your air tool is now ready for use.
You can fit a whip hose with a quick fit coupling if required, available from
your Clarke dealer.

OPERATION
WARNING: NEVER USE STANDARD SOCKETS. THESE MAY SHATTER WITH
SERIOUS CONSEQUENCES. ONLY USE IMPACT SOCKETS DESIGNED FOR
USE WITH IMPACT TOOLS.
FITTING THE IMPACT SOCKET
1. Select the impact socket you
require, which must be in good
condition and fit the tool exactly.
2. Push the socket onto the square
drive shaft as shown.
OPERATING THE IMPACT WRENCH
1. Forward/Reverse rotation is
selected by pressing the
combined Forward/Reverse
operating control according to the
symbol shown on the tool.
2. For normal tightening, the wrench
should be operated in the forward
(F) direction at position.
3. For loosening, the wrench should
be operated in the reverse (R)
direction.
4. Locate the socket over the nut to be tightened or loosened.
5. Squeeze the trigger to start the wrench in either forward or reverse
direction.
6. Release the trigger switch to stop the wrench.
• The anvil will continue to rotate very briefly after the trigger has been
released.

ADJUSTING THE POWER
1. To adjust the power, set the air
regulator to one of the 8 settings
available. (Setting 1-Low, 8 -High)
• These numbers are only for
reference and do not denote a
specific amount of power.
For maximum power when removing
stubborn nuts, turn the supply
regulator to its highest setting.
DISCONNECTING THE AIR SUPPLY
1. Do not disconnect the air supply hose until the compressor has been shut
down and the compressed air released.
2. Refer to the compressor instruction manual for the procedure to shut down
and vent the compressed air.
3. Once the pressure has been released, disconnect the air supply hose from
the air tool.

MAINTENANCE
WARNING: MAKE SURE THAT THE AIR TOOL IS DISCONNECTED FROM THE
AIR SUPPLY BEFORE STARTING ANY CLEANING, OR MAINTENANCE
PROCEDURES.
DAILY
1. Before use, drain water from the airline filter and compressor.
2. Pour a few drops of Clarke air-line oil, into the tool air inlet. This should be
carried out regardless of whether or not an in-line mini oiler is used. If an inline mini oiler is not used, this procedure should be repeated after every
two to three hours of use, or at the start of the working day.
3. Keep the body of the tool clean and free from debris.
CLEANING
1. Grit or gum deposits in the tool may reduce efficiency and cause the tool
to run erratically. This condition can be corrected by cleaning the air
strainer and flushing out the tool with gum solvent oil.
2. Failing this, the tool should be disassembled, thoroughly cleaned, dried
and reassembled.
3. The tool may be dismantled by removing the rear cover using the hex key
supplied prior to replacing any worn or damaged parts. You may prefer to
take the tool to your Clarke dealer if internal maintenance is required.
4. While is a dismantled state, it may be desirable to grease the hammer
mechanism and applying a small amount of good quality bearing grease.
• This may be better left to your Clarke dealer.
• A hex key is provided for removing the end cover from the wrench.
STORAGE
• If the tool is to be stored, or is idle for longer than 24 hours, run a few
drops of Clarke air line oil into the air inlet, and run the tool for 5
seconds in order to lubricate the internal parts. Store the tool safely
in its box in a dry, secure environment.

PERFORMANCE
Please note that factors other than the tool may effect its operation and
efficiency such as reduced compressor output, excessive drain on the airline,
moisture or restrictions in the air-line, or the use of connectors of improper size
or poor condition which will reduce air supply.
**Clarke Air Line Oil (part no. 3050825) is available from your Clarke dealer.
Your Clarke air tool 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.
