tened with soapsuds. Do not use any solvents such
as gasoline, alcohol, ammonia, etc. Chemicals such
as these will damage the synthetic components.
Water inlet filter (Fig. A)
The water inlet filter (3) must be inspected regu-
larly, so as to avoid blockage and restriction of the
water supply to the pump.
Cleaning nozzle (Fig. A, F)
When the nozzle is clogged, it may cause failure.
The nozzle can be cleaned by inserting the 'clean-
ing 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.
Keep the high pressure cleaner in well-ventilated
dry premises with temperature not going below
+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 over-
heating.
• 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.
