OPERATION 17
To avoid damage to the water pump and gearbox (if fitted) never
allow the diesel engine to run on idle/tick over speed for prolonged
periods of time.
MODEL PW200 ONLY
As water enters the pump it will discharge through the EASYSTART
valve in the pump to atmosphere, this is correct. When the trigger
gun is operated the EASYSTART valve will close and the water will
stop discharging. Each time the trigger gun is closed water will
discharge through the EASYSTART valve again. This is a built in
safety feature of this unit to avoid overheating the pump and to ease
starting. The EASYSTART valve also releases any residual pressure
in the system automatically when the engine is stopped.
