SAFETY DEVICES
•Amperecut-outprotectiondevice.
This device stops the high-pressure cleaner operation in the event of excessive power absorption.

15
EN
If it trips, proceed as follows:
- move the master switch (1) to“0”position and remove the plug from the power socket;
- press the spray gun lever (19), so as to release any residual pressure;
- wait 10÷15 minutes for the high-pressure cleaner to cool down;
- make sure the instructions for connection to the power supply are complied with (refer to the
INSTRUCTION MANUAL - SAFETY PRECAUTIONS ), with special reference to the extension used;
- t the plug back in the socket and repeat the start procedure described in the paragraph
“OPERATION” .
•Pressureunloader/regulationvalve.
Valve suitably set by the Manufacturer, which permits regulating the operating pressure by means of
the knob (6) and which allows the pumped uid to return to pump suction, preventing the occurrence
of hazardous pressures when the spray gun is closed or whenever an attempt is made to set pressure
values above max. allowed pressure.
•Spraygunleverlockdevice.
Safety stop (18) which allows locking the lever (19) of the spray gun (9) in closed position, thus preventing
accidental operation
(fig. 2, posiTion s) .

ROUTINE MAINTENANCE
Perform the operations described in the “STOP” paragraph, following the chart shown below.
MAINTENANCE SCHEDULE JOB
After every use •Check the power cable, high-pressure hose, connections, spray gun and
lance hose.
If any of these is damaged, do not use the high-pressure cleaner and
contact a skilled TeChniCian.
Weekly • Cleanthewaterinletlter(21).
Unscrew the quick-fit connection (23) and take out the filter (21).
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dicult cases,useananti-scaleproductorreplace
the filter. To buy spares contact an authorised after-sales centre.
Fit the lter back on and screw the quick-t connection back on.
Monthly • Cleanthenozzle.
Generally speaking, to clean the nozzle, it is enough to pass the pin (12)
provided through the nozzle hole. If this is not successful, change the
nozzle. Buy this from an authorised after-sales centre. The nozzle can be
changed using a 14 mm wrench (not supplied).
• Cleanthedetergentsuctionlter(16).
Generally speaking, to clean the lter, all you need do is pass it under a jet
ofrunningwaterorblowitwithcompressedair.Inthemostdicultcases,
use an anti-scale product or replace it. Only buy spares from authorised
after-sales centres.
• Checkthepumpoillevel(ETM130).
Use the indicator (5) (fig. 1). If topping up is required, contact a skilled
TeChniCian.
