MAINTENANCE
Cleaning of the smoke pump.
Remove lightly adhering soot particles:
For this purpose, make some firm pump strokes, the probe head slightly drawn and no filter paper inserted.

Lightly adhering dirt will peel away also from the valve.
Disassembly of the smoke pump:
A. Unscrew the cylinder cap with left-hand rotation.
B. Carefully pull the piston out of the cylinder. Pay attention not to damage the piston packing on the thread inside of
the cylinder!
When cleaning the piston package, do not take it off the piston rod!
C. Unscrew the probe head with left-hand rotation.
D. Screw off the valve using the supplied key through a left-hand rotation. Put the key securely into the keyhole.
To remove lubricant excesses, use only cleaning agents not affecting plastic material!
Very dirty piston rods may be cleaned with fine-grained sandpaper.

Clean the pump components with a cloth or a suitable brush.

Lubrication of the smoke pump
Before lubricating, the pump has to be cleaned (see chapter: "Cleaning of the smoke pump").
To lubricate the pump only use the provided lubricating oil!
Do not apply too much lubricant oil!
Do not use lubricants containing mineral oil!
A. Drop some lubricant in the cylinder. Spread the lubricant oil on the piston packing and than put the piston back in.
B. Move the piston in the cylinder until it runs smoothly.
C. Mount the remaining components.
TESTING THE PUMP FOR LEAKS
A. Turn the probe head under slight pressure to the valve support (clockwise rotation - clamping position)
B. Hold the pump with handle towards the body so that the probe tube may be closed with the thumb (Of course you
may also use other accessories for closing the probe tube).
C. Pull the pump piston on the handle out for approx. 3-5 cm and let it loose. The handle should spring back in its
initial position: in this case the pump is sealed.
D. If the handle does not spring back in its initial position, the pump is leaked.
Possible causes:
- rubber hose defect
- faulty valve or valve gasket
- crack in the piston packing
