Translation of the original instruction
Troubleshooting:
Cleaning performance with the cleaning attachment is insufficient:
•
The rotation nozzle is not turning
•
Scaly deposits on the rotor
•
Blocked by particles of dirt
•
Turn multiple time manually (make sure the high pressure cleaner is depressurized before doing so)
•
Disassemble and clean
•
In case of excessive and sudden water pressure, the cleaning head can freeze. In this case, press the high pressure
cut off trigger multiple times.
•
Is the high pressure cleaner producing sufficient pressure?
•
Is there a sufficient supply of water to the high pressure cleaner? (Inlet line must be ¾")
•
The rotating nozzle may be worn and need replacing.
• No water is being discharged from the suction unit:
•
Air pocket in the pump
•
Is the power lead for the immersion pump plugged in at the suction basket?
•
The immersion pump is standing in mud and can't extract water
•
Discharge hose kinked.
•
No vacuum or insufficient vacuum:
•
Vacuum flow interrupted due to excessive solid build up in filter basket
•
Machine switched off by thermocouple (caused by vacuum flow interruption / blocked, kinked, or sagging suction
hose / excessive water temperature)
•
Is the top section with motor positioned precisely on the lower barrel?
•
Check the sealing ring on the filter basket between the barrel parts for signs of damage and soiling
•
Check the suction hose coupling
•
Only one suction motor switched on
• Rollers on the cleaning attachment not turning:
•
Casters stuck or dirty. Move attachment back and forth on a durable, insensitive base by applying a slight pressure.
Replace the casters if they cannot be freed.
• Water escaping from the attachment:
•
Clean sealing brushes to remove clogging, or replace brushes.
•
Insufficient vacuum build up
•
Incorrect height setting of sealing brushes
•
Vacuum flow interruption triggered (clean filter basket)
• Unable to actuate cleaning attachment trigger:
•
Release the lock
• Vacuum switching off:
•
Machine switched off by thermocouple (caused by vacuum flow interruption
•
blocked, kinked, or sagging suction hose / excessive water temperature)
•
Check power supply: the circuit breaker may have triggered. Use only 2.5mm² diameter
•
extension lead. Total length must not exceed 30 metes. Completely unwind extension reels.
•
Bellow air filter below suction unit wet and / or soiled
•
Check if the pump plug is plugged into the suction unit (otherwise the water level will rise and the vacuum flow
interrupter will trigger).
•
Switch motors on individually.
•
Attach all machines to different power supplies.
•
Check the 230V power supply.
•
Set both main switches to "0" position. Remove the cause of the malfunction and switch the machine back on after
waiting for approx. 5 min.
