Problem
Remedy
Engine does not start.
Check gaseoline system / clean if required.
Check spark plug / replace if required.
Check oil level and oil level sensor.
Check ignition system / adjust if required.
Engine r.p.m. fluctuates.
Check air filter / clean / replace if required.
Eliminate any leakage in the high-pressure system:
handgun, high-pressure hose, cleaning agent system,
non-return valve, overflow valve and ball valve seat.
Low operating pressure and flow
rate
Check high-pressure nozzle / replace if required.
Check water inlet filter / clean if required.
Check engine speed / adjust if required.
Check spring at overflow valve / adjust if required.
Eliminate any leakage in the high-pressure system (as
mentioned above).
Replace suction and pressure valves.
Replace high and low-pressure seals.
Pump does not draw in cleaning
agent.
Clean cleaning agent system and eliminate leakage.
High-pressure hose is too long or its diameter too small.
Note:
Cleaning agent is only drawn in during full load.
Replace injectors:
- Unscrew front injector as much as possible.
- Then slowly pull through hand start rope.
While doing so, engine must not start.
- The resulting pump pressure pushes both
injectors out of the high-pressure outlet.
