LOW PRESSURE CHEMICAL APPLICATION
The Low Pressure Chemical Application facility is an optional extra
and may/may not be available on the machine.
Totally immerse the filter on the chemical suction hose in the
chemical solution container, connect the opposite end of the hose to
the chemical induction on the water pump.
The model PW9012 is provided with a metering control knob on the
front panel of the machine when the Low Pressure Chemical
Application facility is available. Turn the knob Anti-Clockwise to
increase the flow of chemical, turn Clockwise to reduce the flow.
Dependant on the type of Lance supplied follow the instructions
below induce the flow of chemical through the LANCE, Note chemical
will only be induced at low pressure.
One-Piece Lance assembly, turn the chemical applicator at the end of
the Lance anti-clockwise when viewed from the trigger gun. After a
short delay chemical will be automatically dispensed. To stop the
chemical application, turn the chemical applicator at the end of the
lance clockwise. After a short delay whilst the residue of chemical
works its way through the system the chemical flow will turn off
completely.
Two-Piece Lance, the end of the lance has a Multireg nozzle system,
this allows the angle of the spray to be adjusted by rotating the
nozzle and the pressure to be lowered by pushing the nozzle away
from the end of the lance. The amount of chemical flow induced is
regulated by the knob on the control panel. To stop the flow of
chemical, pull the nozzle assembly back towards the lance.
If chemicals have been used through the machine it is essential that
clean water is allowed to flush through the system until the chemical
residue completely disappears before the engine is stopped.
After the engine is stopped ensure all residual pressure in the
system is released by pulling the trigger gun.
