Maintenance
Required tool: Allen key 8 mm.
Remove the oil-drain plug (8/4) and let the used oil drain into a suitable con-
tainer.
When the flow of oil slows down, screw the oil-drain plug back in, briefly switch
on the pump (max. 10 s) and then switch it off again. Remove the oil-drain
plug once more and drain out the remaining oil.
Screw the oil-drain plug back in (check the gasket and reinstall a new one if
necessary).
Remove the oil-fill plug (8/1) and fill in fresh oil.
Screw the oil-fill plug (8/1) back in.
When an exhaust filter with lubricant return has been installed on the pump
please also exchange the oil there.
We can only guarantee that the pump operates as specified by the tech-
nical data if the lubricants recommended by us are used.
5.5 Cleaning the Inlet Screen
A wire-mesh sieve is located in the intake port of the pump to act as a dirt trap
for foreign objects. It should be kept clean to avoid a reduction of the pumping
speed.
For this purpose, remove the dirt trap (1/2) from the intake port and rinse it in a
suitable vessel with solvent. Then thoroughly dry it with compressed air.
If the dirt trap is defective, replace it with a new one.
The cleaning intervals depend on the application. If the pump is exposed
to large amounts of abrasive materials, a dust filter should be fitted into
the intake line.
