NOTICE

2 minutes without active spraying can
cause serious damage to the pressure
washer.
Shut off the engine:
– before taking a break
– if leaving the machine unattended
– any time active spraying will be
interrupted for more than 2 minutes
Thermal pressure relief valve
If the engine is running in standby mode
without active spraying, the water in the
high-pressure pump heats up to 60 °C
(140 °F). The thermal pressure relief
valve automatically lets the hot water
escape from the high-pressure pump so
that fresh and cool water can flow into
the system.
