General Use
• Open and close the lance trigger to start/stop the flow of water as required.
• The washer is fitted with a return-to-tank pressure regulating valve which bypasses
excess fluid back to the supply tank during normal use and when the lance trigger is
closed
NOTE – It is normal for a small amount of water to be bypassing even when the lance
trigger is open.
• The pressure can be adjusted using the pressure adjusting knob (item 6, fig 1) on the
pressure regulating valve.
• The Washer is supplied with a selection of nozzles to give different fluid projection.
Warning – Risk of damage to pump
Do not let the pump idle in bypass for long periods of time. Never leave the
Washer running unattended.
