Lavorwash MYSTIC, Instructions Manual

Page: 23 / 92

This device enables the machine’s by-pass op-
eration through automatic water discharge
whenever it reaches a temperature of nearly
60°C and cooling working components.
•
CAUTION: appliances that are not pro-
vided with this disposal must not oper-
ate for more than 2 minutes with released
gun. Recycled water raises its temperature
remarkably causing great damages to the
pump.
> GUN SAFETY DEVICE
Whenever the machine has to be stopped, it is
important to engage the safety catch on the
gun so that it cannot be operated accidentally.
> 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 first time after 50 working
hours, with subsequent changes every 500
hours. Use oil SAE 20/30 (750 gr).
CHECKING THE WATER INTAKE FILTER
Inspect and clean the water intake filter on the
intake union periodically. This is important to
prevent fouling which may impair operation 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.
