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 impact sockets or when the wrench is not required for immediate use in order to avoid accidental starting
10. Always store this product in a dry, secure place out of reach of children or untrained users.
11. Always use both hands to control the impact wrench.
12. Always ensure the wrench has stopped before putting it down after use.
13. Never carry the tool by the air hose.

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
---|---

typical air line layout is shown below.

AIR SYSTEM LAYOUT :

1. Air Tool
2. Air Hose 3/8″ (1.D .)
3. Oiler
4. Pressure Regulator
5. Filter
6. Shut Off Valve
7. Whip Hose
8. Coupler Body And Connector
9. Drain Valve
10. 1 /2″ or larger pipe and fitting
11. Air Dryer
12. 1″or larger pipe and fitting
13. Air Compressor
14. Auto Drain
15. Drain Valve

• 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.

• 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.

CONNECTING THE AIRLINE

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 air inlet 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.
**Clarke Air Line Oil (part no. 3050825) is available from your Clarke dealer.

OPERATION

FITTING THE IMPACT SOCKET

| WARNING: NEVER USE STANDARD SOCKETS. THESE MAY SHATTER WITH SERIOUS CONSEQUENCES. ONLY USE IMPACT SOCKETS DESIGNED FOR USE WITH IMPACT TOOLS.
---|---

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 as shown.
   

OPERATING THE IMPACT WRENCH

1. Locate the socket over the nut to be tightened or loosened.
2. Squeeze the trigger to start the wrench.
3. Release the trigger switch to stop the wrench.

• The square drive shaft 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 3 settings available. (Setting 1-Low, 3 -High)

• These numbers are only for reference and do not denote a specific amount of power.
  

SELECTING FORWARD AND REVERSE

| WARNING: WAIT UNTIL THE ANVIL HAS STOPPED ROTATING BEFORE OPERATING THE FORWARD/REVERSE BUTTON.
---|---

Forward/Reverse rotation is selected by pushing the combined Forward/ Reverse knob/power regulator in the direction shown by the arrow on the back of the wrench.

1. For normal tightening, the wrench should be operated in the forward (F) direction.

• For loosening, the wrench should be operated in the reverse (R) direction.
  

DISCONNECTING THE AIR SUPPLY

1. Do not disconnect the air supply hose until the compressor has been shut down and the compressed air released. Residual pressure can be expelled from the tool by running it until it stops.
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/SUBJECT TO USAGE

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 in-line mini oiler is not used, this procedure should be repeated after every two to three hours of use.

• Check the air inlet filter for blockage and clean if needed.
  

Lubricate the motor by first removing the screw shown with a hex key.

• A hex key is provided for removing the end cover from the wrench.
  

Using a grease gun, insert the gun nozzle into the grease port. Several drops of grease are recommended for lubrication.

• This will protect the motor in good rotating condition.
  

INTERNAL 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 or oil.
2. Failing this, the tool should be disassembled, thoroughly cleaned, dried and reassembled.
3. The tool may be dismantled by removing the front cover using the hex key supplied prior to replacing any worn or damaged parts.
4. You may prefer to take the tool to your Clarke dealer if internal maintenance is required.
5. While in a dismantled state, always grease the hammer mechanism applying a small amount of good quality bearing grease.

2. Adjust in-line regulator to open position.
3. Operate tool in short bursts.

Tool will not run. Air flows freely from exhaust.|

1. Motor vanes stuck due to buildup of foreign material.

|

1. Disconnect air supply and rotate tool assembly manu- ally.
2. Try operating tool in short bursts.
3. Tap motor housing gently with a rubber mallet.

Tool will not shut off.|

1. Throttle O-rings dam- aged or ill-fitting in seat.

|

1. Return to Clarke dealer for repair.

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.

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. When not in use, disconnect from air supply, clean & store in a safe, dry place.
