Safety Features
THERMAL RELIEF VALVE
A thermal relief valve is provided to protect the pump from overheating if the spray gun is
closed for an extended amount of time or the nozzle becomes plugged. However, it is
intended to be used as a backup system and every effort should be made to not permit the
pump to heat up.
We recommend to turn the pressure washer OFF if it will not be used for more than 5
minutes. This saves wear on the unit, reduces fuel consumption and extends the life
of the pump by avoiding overheating.
SAFETY LOCK LATCH
To prevent accidental discharge of high pressure water, the safety latch on the trigger
should be engaged whenever the pressure washer is not in use.
LOW-OIL SHUTDOWN
Some engines are equiped with low-oil shutdown systems. If the engine oil level becomes
lower than required, the pressure washer wil automatically shut off. Refer to the engine
manual for this feature. This protects your pressure washer engine from operating without
proper lubrication.
If the pressure washer engine shuts off and the oil level is according to specification,
check to see if the pressure washer is sitting on an angle that forces the oil to shift.
Place on even surface to correct this. If the engine fails to start, there may not be enough
oil to deactivate the low oil level switch.
Pump will overheat and may be damaged,
or cause damage if allowed to circulate
more than 5 minutes
