JOB
• Check the power cable, high pressure hose, couplings, spray gun
and lance hose.
If any of these is damaged, do not use the machine and contact
a Specialized Technician.
• Wall fixing check, where applicable.
• Clean the water inlet filter (30).
Unscrew the quick-fit coupling (32) and take out the filter (30) (see also
Fig. 1). Generally speaking, to clean this all that need be done is pass
the filter under a jet of running water or blow on it with compressed air.
In the most difficult cases, use an anti-scale product or replace the filter.
To buy spares contact an authorized after-sales centre.
Fit the filter back on and screw the quick-fit coupling back on.
• Clean the nozzle.
Generally speaking, to clean the nozzle, it is enough to pass the pin (26)
provided through the nozzle hole. If this is not successful, change the
nozzle. Buy this from an authorized after-sales centre. The nozzle can
be changed using a 14 mm/0.55 in wrench (not supplied).
• Check pump oil level.
For floor operation, put the machine horizontally and check the level
through the oil sight glass (24). If topping up is required, contact a
Specialized Technician.

• Pump oil change.
