INTRODUCTION
Thank you for purchasing this CLARKE Air Riveter.
Before attempting to use this product, please read this manual thoroughly and
follow the instructions carefully. In doing so you will ensure the safety of yourself
and that of others around you, and you can look forward to your purchase
giving you long and satisfactory service.
OPERATING PRINCIPLE
Before use, the rivet gun is oiled in order to ensure that it is properly lubricated.
The rivet is pushed through the hole in the workpiece and the rivet pin inserted
into the rivet gun to take hold of it. Once the rivet gun is activated the throttle
valve allows air through the tool. The pressure of the air forces the rivet pin into
the teeth of the machine which pull the pin up into the rivet. As the pin istaken
up, the base of the rivet expands and this joins the workpiece. The rivet gun
pulls the pin until it breaks off, thereby sealing the rivet.
Pop rivets have limited strength so they are typically used for fastening light
sheet metals. Professionals sometimes refer to these rivets as blind rivets, as the
user cannot see the other side of the material being riveted.

COMPRESSED AIR REQUIREMENTS
• 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 & topped up with oil. Clarke air-line oil should
be used, and the lubricator adjusted to approx 2 drops per minute.
• 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.
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.

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.
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 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 helpful for
sealing threaded connections.
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).

PREPARATION & ADJUSTMENT
CHECKING THE OIL LEVEL
1. Disconnect the riveter from the air
line.
2. Hold upside-down and remove the
air cylinder cap (fig 1) with the
spanner provided.
3. Remove the air/hydraulic piston
assembly (grip the exposed nut
and pull up) as in Fig 2.
4. Add hydraulic oil to the hydraulic
cylinder until the level is just below
the connection with the air
cylinder. See fig. 3.
5. Lightly lubricate the inner wall of
the air cylinder.
6. Replace the air/hydraulic piston
assembly and press in as far as it
will go.
7. Refit and tighten the air cylinder
cap.
ADJUSTING THE STROKE
1. Check that the hydraulic level is correct as above.
2. Remove the frame head using the spanner provided.
3. Check the jaw stroke by using the
spanner/gauge as in figs 4 and 5.
4. Set the distance to <71mm i.e. the
length of the spanner gauge as
shown.

5. If necessary, adjust the stroke as
follows:
• Hold the rear jaw case (fig. 6)
with the larger spanner and
loosen the lock nut with the
spanner/gauge.
• Adjust the stroke by rotating the
jaw case assembly and tighten
the lock nut when adjustment is
complete.
6. Refit the frame head.
CHANGING JAWS
1. Disconnect the tool from the air
line.
2. Remove the frame head (fig. 7)
using the spanner provided.
3. Use both spanners to unscrew the
front jaw case (fig. 8) from the rear
jaw case.
4. Remove the jaws and clean with
solvent and brush. If the teeth are
blunted, replace with new jaws.
5. Reverse the above procedure to reassemble.
OPERATION
1. Select the nosepiece to suit the rivet size and fit to the frame head using
the spanner.
2. Insert the rivet stem fully through the nosepiece and thus into the jaws.
3. Press the rivet body through the pre-drilled hole and hold with the rivet
flange flush on the workpiece.
4. Squeeze the trigger. The rivet will be compressed and the rivet stem will be
ejected into the safety cap.
WARNING: ALWAYS FIT THE SAFETY CAP TO THE REAR OF THE FRAME
BEFORE USE TO PREVENT INJURY FROM EJECTED RIVET STEMS. FIT WITH THE
SLOT FACING DOWNWARDS SO THAT THE STEMS FALL TO THE FLOOR.

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

MAINTENANCE
DAILY
1. Before use, drain water from the air-line and compressor.
2. Maintain the tool with care. Keep it oiled for optimum performance.
3. Lubricate the air tool daily with a high quality air tool oil either via an oiler in
the air supply system or by placing a few drops into the riveter air inlet
immediately before use. 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 hours of constant use.
CLEANING
1. Keep the tool clean.
2. Deposits in the tool may also reduce efficiency. This can be corrected by
cleaning the air inlet and flushing out the tool with gum solvent oil, or failing
this, the tool should be disassembled, thoroughly cleaned, dried and
reassembled.
3. If the tool becomes inefficient and the air supply is of good quality, it may
be necessary to 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.
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-lne Oil (part no. 3050825) is available from your Clarke dealer.
WARNING: MAKE SURE THAT THE AIR TOOL IS DISCONNECTED FROM THE
AIR SUPPLY BEFORE STARTING ANY CLEANING, OR MAINTENANCE
PROCEDURES.

Clarke air-line oil into the air inlet, and depress the trigger in order to lubricate
the internal parts.
When not in use, disconnect from air supply, clean and store in a safe, dry
place.
