> GUN SAFETY DEVICE
Whenever the machine has to be stopped, it is
important to engage the safety catch (S, ref. 5)
on the gun so that it cannot be operated acci-
dentally.
> DESCALING
The descaling procedure must be carried out pe-
riodically with specifi c products. The interval de-
pends on the hardness of the water. This opera-
tion should be carried out by our after-sales serv-
ice, since the descaling product may cause wear
of components. Comply with the regulations in
force when disposing of the descaling agent.
• Liquid softener tank (if any)
Fill the softener tank with our products (in all
cases, with non corrosive products). The dis-
pensing rate is set at a medium value; the After
Sales Services will be able to adapt the setting
to local conditions.
> MAINTENANCE
IMPORTANT: Before doing any work on
the cleaner, discharge the pressure and
disconnect the electricity and water
supplies.
CHECKING THE PUMP OIL LEVEL
Check the oil level periodically. The oil must be
changed for the fi rst time after 50 working hours,
with subsequent changes every 500 hours. SAE
20/30 oil is recommended - Oil capacity 0,7 Kg
CHECKING THE WATER INTAKE FILTER
Inspect and clean the water intake fi lter (ref. 6)
on the intake union periodically. This is impor-
tant to prevent fouling which may impair op-
eration of the pump.
REPLACING THE SPRAY ROD NOZZLE
Replace the nozzle when the pressure drops
below the normal values.
ELECTRIC MOTOR
If the motor malfunctions, it cuts out. Wait 5-10
minutes before restarting. If the problem per-
sists, refer to the "TROUBLESHOOTING" section.
If you are still unable to eliminate the problem,
stop using the machine and contact an Author-
ized Service Centre.
ELECTRICAL CORD
WARNING: Take care not damage the elec-
tric cable. Have a damaged power cord re-
placed immediately by an authorized serv-
ice point or an electrical specialist.
CLEANING THE FUEL FILTER
Check the fuel fi lter (ref. 7) periodically and re-
place if it has deteriorated or is excessively dirty.
