bPress the high-pressure gun and wait until the wa-
ter escaping from the high-pressure gun is free of
air bubbles.
cConnect the spray lance.
dObserve the maximum suction height during suc-
tion operation (see chapter Technical data ).
Strong pressure fluctuations
1. Clean the high-pressure nozzle:
aUse a needle to remove dirt from the nozzle drill.
bRinse the high-pressure nozzle from the front with
water.
2. Check the water supply volume.
Device leaking
1. The device leaks a small amount for technical rea-
