4. Do not operate the tool where there are flammable liquids or gases.

5. Keep the air supply hose away from heat, oil and sharp edges.

6. Do not fit the tool to any stand or clamping device that may damage it.

USE

1. Stay alert and use common sense - do not operate the shear when you are

tired or under the influence of alcohol, drugs or medication.

personnel.

14. Avoid damaging the tool for example by applying excessive force of any

kind.

15. Always maintain the tool with care. Keep it clean for the best and safest

performance.

HAZARDS SPECIFIC TO SHEARS

1. Be careful around all moving parts and pinch points. Always keep your

fingers away from the point of cutting.

2. Ensure material is properly supported during cutting. Use supports for long

material. Hold the material securely to prevent it tilting during the cut. Use

clamps or vices to hold the work piece whenever possible.

3. Take care of sharp edges produced by the cutting operation.

4. Do not use damaged blades. When replacing blades make sure they are

correctly and securely mounted.

5. Anticipate the unexpected tool movement due to a binding blade.

Release the trigger immediately if this occurs.

TRANSPORT & STORAGE

1. Never carry the tool by the air hose.

2. Never carry the tool with your finger on the trigger.

3. When not in use the tool must be disconnected from the air supply and

stored in a dry place out of the reach of children (preferably in a locked

cabinet).

THE COMPRESSED AIR SUPPLY

• Use only clean, dry, regulated compressed air as a power source.

• Air compressors used with the impact wrench 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 impact wrench. 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. SAE 10 oil should be

used, and the lubricator adjusted to approx 2 drops per minute.

• The minimum hose diameter should be 5/16”(8mm) ID and fittings

should have the same internal dimensions.

• 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 unclean air will

shorten the life of the tool due to faster wear and is a possible safety

hazard.

BEFORE USE

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 air tool. Remove the

oil fill screw from the side of the

mini oiler and fill with Air-line Oil

available from your CLARKE

dealer. Replace the screw

before using the tool.

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 inlet strainer 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.

6. 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).

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.

OPERATION

OPERATING THE AIR SHEAR

1. Place the cutter head against the

side of the sheet metal you want

to cut.

2. Squeeze the trigger to start the

metal shear.

3. Maintain constant pressure to

move the tool through the sheet

metal.

4. Release the trigger switch to stop

the metal shear.

WORKING AT AN ANGLE

The shears can be set to operate in

line with the handle or at an angle, for

example, if working in a confined

space.

1. To do this, re-set the nose section in

its new position by slackening the

hex screw shown using the key,

and rotating the nose assembly to

the angle required.

• It can be set at any angle

required.

2. Ensure you have re-tightened the screw before using the shear.

DISCONNECTING THE AIR SUPPLY

Do not disconnect the air supply hose until the compressor has been shut

down and the compressed air released.

1. Refer to the compressor instruction manual for the procedure to shut down

and release the compressed air.

2. Once the pressure has been released, disconnect the air supply hose from

the air drill.

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

MAINTENANCE

DAILY

1. Before use, drain water from the air tank, air line and compressor.

2. Pour a few drops of CLARKE airline oil, into the 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.

WEEKLY

1. 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.

3. After extensive use, remove the inlet screen filter and flush out the

mechanism with gum solvent oil or an equal mixture of SAE No10 oil and

paraffin. Allow to dry before use.

4. Clean the air inlet filter screen inside the hose adaptor.

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.

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.

WARNING: MAKE SURE THAT THE TOOL IS DISCONNECTED FROM THE AIR

SUPPLY BEFORE STARTING ANY CLEANING, OR MAINTENANCE

PROCEDURES.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

REPLACING BLADES

After heavy use, the blades and knife

may become damaged and require

replacement. Replacements are

available from your Clarke dealer.

1. To remove both blades and the

knife, unfasten the three socket

headed screws using the hex key

provided.

• The nose section will become

detached from the body

connector.

2. Remove and replace the knife and the left/right-hand blades and re-

tighten the screws.

• Take care not to lose the knife pivot bush shown and replace it when

refitting the knife.

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.

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.

ACCESSORIES

A wide range of accessories is available including filter/regulators, lubricators,

high-pressure hoses (5 to 50 metres) etc.
