by authorized service center, that have the proper tools and
expertise.
POWER CORD
To avoid shock or fire hazard, if the power cord is
worm or cut, or damaged in any way, have it re-
place immediately.
Electrical connection cables often suffer insula-
tion damage. Possible causes are:
1. Punch points when connection cables are run
through window or door gaps.
2. Kinks resulting from incorrect attachment or
laying of the connection cable.
3. Cuts resulting from running over the connect-
ing cable.
4. Insulation damage resulting from forcefully
pulling out of the wall socket.
5. Cracks through aging of insulation.
Such defective electrical connection cables must
not be used as the insulation damage makes them
extremely hazardous.
FUEL FILTER
Remove and replace the inline fuel filter (Fig. 14)
from time to time.
WATER FILTER
Clean the water intake filter regularly and free it
from any impurities (Fig. 15).
NOZZLE
The high pressure nozzle fitted on the lance must
be changed from time to time, as this component
is subject to normal wear during use. Wear may
generally be detected by a drop in the working
pressure of the pressure washer. To replace it,
consult your supplier and/or dealer for instruc-
tions.
DESCALING
Descaling must be carried out, by official service
center only, from time to time because the scale
present in the water partially deposits inside the
hydraulic circuit and the coil which with time be-
comes clogged.
CLEANING
Use a small soft brush to clean the outside of the
