Water inlet filter (Fig. A)
The water inlet filter (3) must be inspected
regularly, so as to avoid blockage and restriction of
the water supply to the pump.
Cleaning nozzle (Fig. A, G)
When the nozzle is clogged, it may cause failure.
The nozzle can be cleaned by inserting the
'cleaning pin' (13) into the tip to remove filth.
Storage and frost protection
The high pressure cleaner and accessories that are
not completely drained can be destroyed by frost.
Completely drain the high pressure cleaner and
accessories and protect them against frost.

+5°C.
MALFUNCTION
Should the machine fail to function correctly, a
number of possible causes and the appropriate
solutions are given below:
1. When switched on, the machine will not start
working.
• Plug is not well connected or electric socket is
faulty.
• Check plug, socket and fuse.
• The mains voltage is lower than the minimum
requirement for start up.
• Check that the mains voltage is adequate.
• The pump is stuck.
• Refer to after storage instructions. Switch
off the unit and let the motor cool.
• Thermal safety has tripped.
• Leave the lance open with water coming
through.
2. Fluctuating pressure
• Pump sucking air.
• Check that hoses and connections are
airtight.
• Valves dirty, worn out or stuck. Pump seals
worn.
• Clean and replace or refer to dealer.
3. Water leaking from the pump
• Seals worn out.
• Check and replace, or refer to dealer.

4. The motor stops suddenly
• Thermal safety switch has tripped due to
overheating.
• Check that the mains voltage corresponds
to specifications. An extension cable, which
is too thin, and too long can cause a voltage
drop and cause the motor to overheat.
Leave to cool down. Use heavy duty
extension cables.
5. The pump does not reach the necessary
pressure.
• Water inlet, filter is clogged.
• Clean the water inlet filter.
• Pump sucking air from connections or hoses.
• Check that all supply connections are tight.
• Suction/ delivery valves are clogged or worn
out.
• Check that the water feeding hose is not
leaking.
• Unloader valve is stuck.
• Clear or respire valves.
• Lance nozzle incorrect or worn out.
• Loosen and re-tighten regulation screw
check and/ or replace.
Repairs and servicing should only be
carried out by a qualified technician or
service firm.
