Maintenance
Cleaning of the soot pump
Remove lightly adhering soot particles:
For this purpose, make some expeditious pump
strokes with the pump, the probe head slightly drawn
and no filter paper inserted. With it, lightly adhering dirt
also peels away from the valve.
Disassembly of the soot 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!
For cleaning the piston package, in no case take it off
the piston rod!
C Unscrew the probe head with left-hand rotation.
D Screw off the valve using the enclosed key through
left-hand rotation. Put the key securely into the
borehole.
For removing lubricant residues, use only cleaning
agents not affecting plastic material!
Strongly effloresced piston rods may be cleaned
with fine-grained sandpaper.
Clean the pump components with a cloth or a
suitable brush.
Lubrication of the soot pump
Before lubricating the relevant parts of the soot pump,
it has to be cleaned
(see: Cleaning of the soot pump)!

Do not apply too much lubricating oil!
Do not use lubricants containing mineral oil!
A Insert somewhat oil in the cylinder. Apply and
distribute lubricating oil on the piston packing and than
mount it.
B Move the piston in the cylinder until it is smooth
running.
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: The pump is sealed.
or
D The handle does not spring back in its initial
position: The pump is leak.
Possible causes:
- rubber hose defect
- valve / valve gasket is not OK
- crack in the piston packing
