RX550 Electric Pressure Washer
•
The trigger gun must not be jammed in position during operation.
•
Never tie knots or kink the high-pressure hose. Do not use damaged high-pressure hoses.
•
All hose connections must be properly sealed.
Thermal Relief Valve
A thermal relief valve is provided to protect the pump from overheating if the spray gun is closed for an
extended length of time or the nozzle becomes obstructed. However, it is only intended to be used as a
backup system and every effort should be made to ensure that you pull the spray gun trigger to allow
water flow so that there are no blockages in the system.
Safety 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.
