• If you are working with hot water, rotate the SWT switch to the
OFF position.
Continue working with cold water for a few minutes to allow the
•
boiler to cool down properly
Close the water supply tap

7.6 OPERATING PROCEDURES

The Super and Super Plus series high pressure washers are equipped
with a "delayed total lockout system", which stops the machine a few
seconds after the gun is released. Pressing the gun again will cause
the machine to restart normally.
The high-pressure cleaner is equipped with a "micro leak detection"
function, which will stop the machine after repeated starts caused by
small leaks. If this function is tripped, the machine will stop. To
restart it (reset), first rotate the main switch to "OFF" and then back
to "ON"
The high pressure washer is equipped with a "time-out" function,
which stops the machine after 20 minutes of inactivity. If this
function is tripped, the machine will stop. To restart it (reset), first
rotate the main switch to "OFF" and then back to "ON" This function
can be excluded but this operation is to be carried out only by expert
personnel.

7.7 PRESSURE CONTROL VALVE

The pressure control valve allows the water pressure to be reduced
from its maximum value down to about 25 bar. Reducing this value,
the valve partializes the quantity of water to be heated thus allowing
the water's temperature to be increased. This function is intended to
obtain short periods of water spray at temperatures greater than
100°C (this value is variable depending on the model and its flow
rate).
WARNING
With the water at such high temperatures, great care must
be taken when handling the jet.
WARNING
Prolonged use at high temperatures causes rapid
limescale buildup.
7.8 WASHING WITH DETERGENT
Open the tap located on the panel and then activate the lever on the
gun; the pump will automatically draw detergent from the tank. Spray
the surface to be treated, release the lever on the gun and then close
the detergent tap. Activate the lever on the gun again to begin rinsing.
Note: detergent delivery will continue for a few more seconds once
the tap is closed due to residual product in the piping.
WARNING
Do not spray detergent on hot surfaces and then rinse
within the time recommended by the manufacturer of the
chemical product.

8. ROUTINE MAINTENANCE

WARNING
During routine maintenance, cleaning or extraordinary
maintenance operations, it is mandatory to put on the
personal protective equipment provided.
WARNING
Non-compliance with these safety instructions could
result in injury, death or damage to the equipment.
WARNING
All maintenance or cleaning operations are to be carried
out with the machine switched off, the spark plug cable
disconnected and only once the motor has cooled to avoid
burns and fire hazards. No one other than maintenance
personnel should be permitted to approach the machine.
