PRIMING THE WATER PUMP
Each time the machine is put into operation the water pump will
require priming before it will operate correctly. Priming the pump and
hoses removes any air which may be trapped in the system and
which may affect the correct operation of the pump and prevent the
full working pressure from being reached.
To prime the water pump follow the instructions below:-
Connect up the suction hose, if drawing from a tank keep the suction
hose as short as possible and never exceed 3 metres.
Start the engine and run up to 3/4 full speed
Hold the trigger gun open until a constant flow of water emerges, this
can take as long as 30 seconds, if after 30 seconds no water has
emerged stop the engine and investigate the cause.
Close trigger, increase the engine speed and use in normal manner.
