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.
