MAINTENANCE
SCHEDULE
JOB
Every time it is
used
• Check the high pressure hose, fittings, spray gun and lance hose.
If one or more parts are found to be damaged do not, under any circumstances,
use the high pressure cleaner and contact a Specialized Technician.
• Check pump oil level.
• Remove all dirt and debris from the cooling fins on the engine, from the air
inlet grids, from the mechanisms and rev regulator springs (refer to the engine
operating and maintenance manual).
Weekly
• Clean the water inlet filter (23).
Unscrew the cap (61) and take the cartridge out (63), (see Fig. 4). It is normally
enough to put the cartridge under running water or blow it with compressed air
to clean it. In the most difficult cases, use a scale remover or replace it, contacting
an authorised assistance centre to buy the new cartridge.
Mount the cartridge and screw the plug back down.
Monthly
• Clean the water inlet filter (23) (refer to what has been explained previously).
• Clean the nozzle.
It is normally enough to put the needle (29) supplied through the hole of the
nozzle to clean it. If the results are not good, replace the nozzle purchasing it from
an authorised assistance centre.
The professional fixed fan nozzle mounted on the nozzle holder heads (24) can
be replaced using a 14 mm box spanner (not supplied).
• Oil or grease the rotating or sliding parts the operator is able to reach (refer also
to the engine operating and maintenance manual).
• Check soundness of the water inlet and outlet circuits.
• Check clamping of the pump to the engine and the engine to the frame.
If clamping is found to be insecure do not, under any circumstances, use the
high pressure cleaner and contact a Specialized Technician.
CAUTION
• When working, the high pressure cleaner should not be too noisy and there should be no obvious
drips of water or oil underneath it. If this is the case have the machine checked by a Specialized
Technician.
SPECIAL MAINTENANCE

Also remember to carry out the special maintenance jobs listed in the engine operating and maintenance
manual.
