CAUTION
Ensure the operator is aware that when the trigger is pulled, water at high
pressure can cause the lance to kick - it should therefore be held firmly.
In addition, care must be taken to ensure that the nozzle is NOT aimed at
an area where the water jet will cause damage, i.e. away from people,
animals, windows - greenhouses etc., and be aware that splash back
could also cause damage if the jet is trained on a nearby wall etc.
If you intend to use the chemical injection facility,
fill the detergent tanks at thr rear of the unit, shown
in Fig.9, with the requisite detergent.
The amount of detergent that enters the system
may be regulated by turning the knob on the front
of the unit shown in Fig. 10.
Note that two tanks are provided so that a
detergent/cleaner may be used in one and a wax/
shampoo in the other, for example.
By turning the regulator knob to the left - the medium
in the left tank (looking from the front) will be used, and
turning to the right-will use the right tank

15:1...Min-approx. 1000:1.
SHUTTING DOWN THE MACHINE
If the chemical injection facility has been used, turn the pressure adjuster on the
end of the lance to HIGH pressure, and allow the pump to run for a minute or so
until the water being ejected is foam free, then switch OFF the pump.
Disconnect from the mains electrical supply, and turn OFF the water supply -

IMPORTANT:
ALWAYS operate the lance trigger once more to ensure there is no pressure in the
high pressure hose. NEVER disconnect the high pressure hose without first pulling
the trigger.
