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. ALWAYS take care of sharp edges produced by the cutting operation.
4. DO NOT use damaged punches/blades. When replacing cutting tool parts

COMPRESSED AIR REQUIREMENTS
A typical air line layout is shown below. 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.
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.

7
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
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 (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.
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 air tool.
ACCESSORIES
A wide range of accessories is available including filter/regulators, lubricators,
high-pressure hoses (5 to 50 metres) etc.
Contact your CLARKE dealer for further information or CLARKE International
Service Department on 01992 565333.
CLARKE Air Line Oil (part no. 3050825) is available from your CLARKE dealer.

BEFORE USE
When opening the carton, check that all the items are present. Any damage
or deficiency should be reported to your CLARKE dealer immediately.
The carton should contain:
• Air Nibbler tool
• Male inlet adaptor
• Spare Die and blade
1. Remove the plastic blanking plug
from the air inlet connection.
2. Pour 2-3 drops of CLARKE airline oil
into the air inlet port. This should be
done regardless of whether or not
a lubricated air supply is to be
used.
3. If required, connect an in-line mini
oiler to the tool.
• A mini oiler helps to prolong the
life of any air tool.
4. Connect a suitable hose as shown or use the snap connector supplied to
connect directly to the hose.
5. Connect the other end of the hose to the compressor.
• PTFE tape may be useful for sealing threaded connections.
6. Turn on the air supply and check for air leaks. Rectify any found before
proceeding.
7. If using a mini oiler, place a sheet of paper next the exhaust port and
squeeze the trigger for approximately 30 seconds. The oil volume is
correctly set when a light stain of oil can be seen on the paper. Excessive
oil should be avoided.
Your air nibbler is now ready for use.
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF AIR
COMPRESSORS AND A COMPRESSED AIR SUPPLY.

OPERATION
The punch and die can be rotated through 360oto aid access and obtain
maximum consumable life.
1. To do this, loosen the locknut with
a 22 mm spanner and rotate the
die on the blade until it is in the
right position for the job in hand.
2. Hold the die steady with a 15mm
spanner on its flats and retighten
the locknut.
3. Ensure your workpiece is properly
secured and marked out.
4. Connect the nibbler to the airline.
5. Start the nibbler by squeezing the throttle lever.
6. Introduce the sheet metal into the slot in the end of the die. Apply only light
pressure to move the tool in the desired direction through the material.
7. Do not allow the nibbler to run freely for long periods of time as this could
harm the bearings.
It is recommended that a whip hose with a swivel (not included) be used to
prevent twisting, kinking and resultant wear to the air hose.
CHANGING THE BLADE AND DIE
1. Loosen the locknut using a 22mm
spanner.
2. Unscrew the die (with the locknut
on it) from the body of the tool.
3. Using a 9mm ring spanner, unscrew
the blade retainer with the blade.
4. Remove the old blade from the
retainer and insert the new one.
5. Screw the retainer back into place
and tighten with the ring spanner.
6. Slide the die and locknut over the
blade and screw it back into the
tool until the tip of the blade is flush
with the bottom of the die. Rotate

10
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
the die into the best position required by the workpiece. Hold the die
steady with a spanner on its flats and re-tighten the locknut.
NOTE: The open side of the die should be straight ahead and in
alignment with the metal being cut.
DISCONNECTING THE AIR SUPPLY
1. Do not disconnect the air hose until the supply is isolated at a shut-off
valve.
2. Once the pressure has been isolated, disconnect the air supply hose from
the air tool.
3. Shut down the compressor at the end of the work session.
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 tool and store in a safe, dry
place.
When storing, replace the blanking plug to the air inlet once the airline is
disconnected.

MAINTENANCE
Please note that factors other than the tools condition may effect its operation
and efficiency. These include reduced compressor output, excessive drain on
the airline, moisture or restrictions in the air-line, or the use of connectors of
incorrect size or poor condition which will reduce air supply.
DAILY
1. Before use, drain water from the air-line and compressor.
2. Lubricate the tool 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
tool immediately before use. This
should be carried out regardless of
whether or not an in-line lubricator
is used.
3. Oil can be added via the
lubrication cover on top of the
nibbler. It is screwed on finger tight.
CLEANING & OVERHAUL
1. Keep the tool clean and free from debris.
2. If the tool 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 tool with gum solvent oil or an equal mixture of SAE No10 oil and
paraffin.
4. Failing this, the tool should be disassembled, thoroughly cleaned, dried
and reassembled. You may prefer to take the tool to your CLARKE dealer if
internal maintenance is required.
WARNING: MAKE SURE THAT THE TOOL IS DISCONNECTED FROM THE AIR
SUPPLY BEFORE PERFORMING ANY CLEANING OR MAINTENANCE.
