Remedy
Engine does not start.
Check / clean fuel system.
Check engine stop lever.
Check decompression lever.
Check starter battery and charging regulator.
Engine r.p.m. fluctuates.
Check / clean / replace air filter.
Eliminate leakages in high-pressure system:
handgun, high-pressure hose, cleaning agent system,
non-return valve, overflow valve, valve seat of the ball.
Low operating pressure and flow
rate
Check / replace high-pressure nozzle.
Check / clean water inlet filter.

Eliminate leakages in high-pressure system (as
mentioned above).
Check / adjust spring at overflow valve.
Replace suction and pressure valves.
Replace high-pressure and low-pressure seals.
Pump does not draw in any
cleaning agent.
Clean cleaning agent system and eliminate leakages.
High-pressure hose is too long or its inner diameter too
small.
Note:
Cleaning agent is only drawn in during low-
pressure operation when the servopress handgun
is completely opened.
Replace injector:
- Unscrew front injector as much as possible.
- Then slowly pull through hand start rope.
While doing so, the engine must not start.
- The resulting pump pressure pushes both
injectors out of the high-pressure outlet.
