Cause and Rectification

Refuel the engine
(For any further, refer to the separately supplied engine manual.
The strain filter is clogged or the water supply from the tap is
insufficient.
Clean the strain water filter.
If there isn't enough water-flow through the tap, the machine
should suck from a filled water vat or tank.
The high pressure nozzle is partly clogged.
Turn off the High Pressure Cleaner, dismantle the high-pressure
nozzle and remove the extraneous matter. Replace if damaged.
The high-pressure nozzle is clogged or there is dirt in the by-pass
valve. The pump sucks air.
Turn off the High Pressure Cleaner. Clean the nozzle. Inspect the
low pressure supply,
or while the spray-gun trigger is activated turn the machine on
again. Repeat the procedure again; now with the trigger released. If
the problem still occurs, the by-pass valve should be dismantled
and the extraneous matter removed.
There is dirt in the valves.
Turn off the High Pressure Cleaner. Dismantle the valve bolts and
the valves, remove the dirt and check to ensure the valve flaps are
movable and fits tightly.
