2. Dress appropriately: - do not wear loose clothing or jewellery. Tie long hair
out of the way.

3. Keep children and visitors away - do not let children handle the drill.

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

5. Stay alert and use common sense - do not operate the saw when you are
tired or under the influence of alcohol, drugs or medication.

6. Always wear eye protectors when using the saw - Eye protection must
provide protection from flying particles from the front and the side.

7. Always wear ear protectors and face mask when using the saw.

8. Do not overreach - Keep proper footing and balance at all times.

USE OF AIR POWERED TOOLS

1. Never use any type of bottled gas as a source of power for an air tool.

2. Do not connect the air supply hose with your finger on the trigger.

3. Do not exceed the maximum pressure for the saw 90 psi / 6.2 bar.

4. Check hoses for leaks or worn condition before use and ensure that all
connections are secure.

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

6. Do not use this saw for any other purpose than that described in this
manual.

7. Do not fit this saw to any stand or clamping device that may damage it.

8. Do not carry out any alterations or modifications to this saw.

9. Always disconnect from the air supply when:

• Performing any maintenance

• The saw is not in use.

• Moving to another work area.

• Passing the saw to another person.

10. Never use the saw if it is defective or operating abnormally.

11. Always ensure the saw has stopped before putting it down.

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.

• 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 air 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.

Parts & Service: 020 8988 7400 / E-mail: [email protected] or [email protected]

• Never exceed the maximum operating pressure for the air tool. It is

recommended that air pressure to this tool does not exceed 90 psi
(6.2 bar) 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

WARNING: MAKE SURE THAT THE SAW IS DISCONNECTED FROM THE AIR
SUPPLY BEFORE INSTALLING, REMOVING OR REPLACING THE BLADE.

FITTING THE BLADE

1. Slide the blade into the saw as
shown.

2. Secure the blade by tightening the
grub screw shown using the
hexagonal key supplied.

3. Identify the material and then
select the correct blade for your
operation.

4. Always use the correct saw blade
for the material for smooth and
fast cutting.

• It is recommended that

operators use 32T blades for cutting light sheet metal, body panels,
exhaust pipes, etc., use 24T blades for general purpose sawing
including aluminum and other soft materials, and use 18T blades for
cutting plastic, reinforced fiberglass, wood, etc.

CONNECTING THE AIR LINE

1. Remove the protective plug from
the air inlet and connect a suitable
hose as shown.

2. A gauze filter is fitted within the air
inlet. Ensure this is always in place
and is kept clean. The air line is
connected to the adapter,
preferably via a quick release
coupling (not supplied).

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

4. Ensure the trigger is NOT depressed
when connecting the air line.

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.

6. If required, connect an in-line mini oiler to the airline close to the air tool.

• A mini oiler helps to prolong the life of any air tool.

7. If a mini-oiler is not being used, run a few drops of oil through the air tool
before use. It can be entered through the airline inlet or via the hose at the
nearest connection to the air supply.

• Your sabre saw is now ready for use

• You can fit a whip hose with a quick fit coupling if required

(available from your Clarke dealer.)

OPERATION

OPERATING THE SAW

1. Slide the safety lock forward and
squeeze the trigger.

• Allow the saw to reach full

speed before use.

2. Release the trigger to stop the
saw. When the blade has stopped
remove it from the workpiece.

DISCONNECTING THE AIR SUPPLY

1. Do not disconnect the air supply hose until the air supply has been shut
down and the compressed air released from the hose.

2. Refer to the compressor instruction manual for the procedure to shut down
and release the compressed air.

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

MAINTENANCE

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

Please note that factors other than the tools condition 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 connector

DAILY

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

2. Lubricate the saw daily for optimum performance. Use a high quality airline
oil either via a lubricator in the air supply system or by placing a few drops
into the air inlet immediately before use. This should be carried out
regardless of whether or not an in-line lubricator is used.

CLEANING & OVERHAUL

1. Keep the saw clean and free from debris.

2. If the saw becomes sluggish and the air supply is of good quality, it may be
necessary to replace worn or damaged parts.

3. Grit or gum deposits in the mechanism may eventually reduce efficiency.
This condition can be corrected by cleaning the air inlet filter and flushing
out the saw with gum solvent oil or an equal mixture of SAE No10 oil and
paraffin.

4. Failing this, the saw should be disassembled, thoroughly cleaned, dried
and reassembled. You may prefer to take the saw to your CLARKE dealer if
internal maintenance is required.

STORAGE

If the saw 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 depress the trigger in order to lubricate
the internal parts.

When not in use, the saw should be disconnected from the air supply and
stored in a dry place out of the reach of children. Avoid storing in a damp
environment.

ACCESSORIES

A wide range of accessories is available including filter/regulators, lubricators,
high-pressure hoses (5 to 50 metres) etc.
