6. Do not exceed the maximum pressure for the tool of 90 psi / 6.2 bar.
7. Check hoses for leaks or worn condition before use, and ensure that all connections are secure.
8. Keep the air supply hose away from heat, oil and sharp edges.
9. Do not use the tool for any purpose than that described in this manual.
10. Do not fit the tool to any stand or clamping device that may damage it.
11. Do not carry out any alterations or modifications to the tool.
12. Always disconnect from the air supply when:
    • Performing any maintenance.

SAFETY SYMBOLS

The following safety symbols are to be found on the machine.

OVERVIEW

The CAT134 and CAT135 ratchet wrenches are ideally suited to quick removal and installation of nuts, bolts, and other fasteners where space is limited.

ACCESSORIES

A wide range of accessories is available including filter/regulators, lubricators, high-pressure hoses (5 to 50 metres) etc. Contact your Clarke dealer or the Clarke International Service Department for further information.

COMPRESSED AIR REQUIREMENTS

WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF COMPRESSORS AND A COMPRESSED AIR SUPPLY.

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 Daily
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 Daily

• 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 minimum 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 air supply 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 air tool. Read the instructions supplied with the mini-oiler before use.

2. If a mini-oiler is not being used, insert a few drops of oil into the tool through the air inlet before use.

3. Connect a suitable hose as shown.

4. Connect the other end of the hose
   to the compressed air supply.

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

USING THE DIRECTION CONTROL
WARNING: ALWAYS WAIT UNTIL THE DRIVE SHAFT HAS STOPPED ROTATING BEFORE OPERATING THE DIRECTION CONTROL.

To select the direction of rotation turn the direction control as follows.

• For tightening, turn the direction control anti-clockwise to F (Forward).
• For loosening, turn the direction control clockwise to R (Reverse).

USING THE AIR RATCHET

1. Select the socket you require.
   • Push the socket onto the square drive shaft. It clicks into place when secure.
2. Place the socket over the nut.
   • Take care that the socket is firmly engaged.
3. Squeeze the trigger against the body of the tool to start.
4. Release the trigger to stop the tool.
5. Always ensure the tool has stopped before putting it down.
6. When releasing very tight fastenings initially break loose by hand. Squeeze the trigger and the air tool will complete the job.
7. If necessary, use penetrating oil to assist in freeing off rusted fasteners.
8. When assembling, start turning fasteners by hand, then set the rotation forward or reverse. Apply the tool gently and squeeze the trigger to tighten with power.
9. Final tightening should be completed by hand.

SETTING THE SPEED

1. Set the tool speed by rotating the control to one of the four settings.
   • The graduations on the speed control indicate the speed setting when aligned with the reference mark on the air inlet.
   •  Speeds available are: 45, 85, 140 or 180 rpm (+/-10%).
     NOTE: When critical torque values are not required, turn the nut or bolt until it is snug – slightly tighter if gaskets are used between surfaces. Where torque settings are critical, the final tightening of nuts or bolts must be by hand, using a calibrated torque wrench.

SETTING THE EXHAUST DEFLECTOR
The direction of the exhaust air leaving the tool can be adjusted by rotating the exhaust deflector. Twist the exhaust deflector sleeve to direct the air as required to deflect air away from the workpiece or operator.

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.
4. Store the tool safely in its box in a dry, secure environment.

MAINTENANCE

WARNING : MAKE SURE THAT THE AIR TOOL IS DISCONNECTED FROM THE COMPRESSED AIR SUPPLY BEFORE STARTING ANY CLEANING, OR MAINTENANCE PROCEDURES.

DAILY

1. Before use, drain water from the compressed air supply.
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.

WEEKLY
Check the air inlet screen filter for blockage and clean if necessary.

CLEANING

1. Keep the body of the tool clean and free from debris.
2. Grit or gum deposits in the tool may also reduce efficiency. This condition can be corrected by cleaning the air strainer and flushing out the tool with gum solvent oil, or failing this, the tool should be disassembled, thoroughly cleaned, dried and reassembled. This is better left to your Clarke dealer.
3. After extensive use, remove the inlet screen filter and flush out the mechanism with gum solvent oil or an equal mixture of Clarke air-line oil and paraffin. Allow to dry before use.
4. Clean the air inlet filter screen inside the air inlet.
5. If the tool runs erratically or becomes inefficient, and the air supply is of good quality, it may be necessary to dismantle the air motor and replace worn or damaged parts. You may prefer to take the tool to your Clarke dealer if internal maintenance is required.

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.

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.
