Maintenance
E. Cleaning the Gas Ballast Intake Filter
Tools required: Open-jaw or box wrenches 10 mm, 17 mm.
Remove the fastning screws at the top of the pump-cylinder cover (7/51a-
52a), loosen the pump foot (7/94a) at the bottom of the cover and take off
the cover.
Release the clips on the gas ballast filter.
Clean the filter using a suitable solvent. Then dry it. Reassemble in the
reverse sequence.
F. Cleaning the Dirt Trap
Tools required: open-jaw or box wrenches 10 mm, 17 mm.
A dirt trap for coarse particles is located in the intake flange of the pump
(7/57). It should be kept clean to avoid reduction of the pumping speed.
The dirt trap consists of two wire-mesh screens. The outer one is accessible
by removing the intake line. If it is only slightly dirty, just wipe off the screen
from the outside. If it is very dirty, disassemble the intake flange.
To do so, remove the fastening screws at the top of the pump-cylinder cover
(7/51a-52a), loosen the pump foot (7/94a) at the bottom of the cover and
take off the cover.
Remove four screws and take off the intake flange (7/57) and gasket (7/55).
Remove the retaining ring from inside the intake flange (7/57). Take out both
wire-mesh screens and clean them using a suitable solvent.
Reassemble in the reverse sequence. We recommend replacing the gasket
(7/55) with a new one.
G. Checking the Anti-Suckback Valve
Tools required: open-jaw or box wrenches 10 mm, 17 mm.
Keep the anti-suckback valve clean to ensure proper operation of the pump.
If the pump is exposed to large amounts of dust or dirt, we strongly recom-
mend installing a dust filter upstream.
First disconnect the intake line.
Then remove the fastening screws at the top of the pump-cylinder cover
(7/51a-52a), loosen the pump foot (7/94a) at the bottom of the cover and
take off the cover.
Remove four screws and take off the intake flange (7/57) and gasket (7/55).
Remove the spring and anti-suckback valve, and replace them if required.
If the anti-suckback valve closes too soon, carefully compress the spring
slightly. The top edge of the valve should be about 1-2 mm away from the
bottom side of the intake port.
Reassemble the spring with the correct orientation: small diameter to the top.
Do not screw the spring into the generator suction hole !
Reassemble the intake port. We recommend replacing the gasket (7/55) with
a new one.
