HIGH and LOW
PRESSURE
is set by
pulling IN or pushing
OUT the nozzle as
shown in Fig. 8.

NOTE: The detergent facility will ONLY operate at LOW PRESSURE
B. HOT WASH
Follow the same procedure as for the cold
wash, but switch the burner ON once the
pump has been switched ON, by pressing
the rocker switch on the side of the unit,
denoted by the symbol to‘I’ (ON).
If the burner does not start or smoke issues
from the exhaust, it is likely that the fuel system
requires bleeding. To do this, first remove the
top cover, ensuring the machine is
disconnected from the mains supply, then
open the bleed valve shown in Fig.11 . When fuel is emmitted, retighten the
valve, and replace the top cover.
Take care when using the HOT WASH facility. DO NOT forget that certain
components get extremely hot during operation, and will remain so for a period
after switching OFF. This includes the metal parts of the lance.
High pressure may also be regulated at
the knob on top of the unit, shown at ‘A’
in Fig. 10. By turning clockwise the
pressure is reduced. A scale alongside
the knob ‘B’, registers the outlet pressure.
USING DETERGENTS
Detergents will automaticlly be drawn
and mixed with the water jet when the
nozzle is set to LOW PRESSURE.

IN -HIGH pressure OUT - LOW pressure
Additionally a FAN SPRAY may be used by twisting the nozzle as shown in Fig.9.
C. SHUTTING DOWN THE MACHINE
If the burner has been used, switch it OFF FIRST by pressing the rocker
switch, on the side of the unit, to ‘O’ (OFF).
Allow the pump to run for a minute or so until the water being ejected is
cold then switch OFF the pump by pressing the switch to ‘O’ (OFF).
If the chemical injection facility has been used, set the lance to HIGH
pressure, and allow the pump to run for a minute or so until the water
being ejected is cold and foam free,then switch OFF the pump by pressing
the switch to ‘O’ (OFF).
Disconnect from the mains electrical supply, and turn OFF the water supply
- disconnect where appropriate.
Operate the lance trigger once more to ensure there is no pressure in the high
pressure hose. NEVER disconnect High pressure hose without operating trigger.
MAINTENANCE
WARNING:
Ensure the machine is disconnected from the mains supply before
carrying out any adjustment, servicing or maintenance.
AFTER EACH USE
When using chemical detergents, always ensure the system is thoroughly flushed
out after use as described in ‘Shutting Down The Machine’above.
Ensure the hoses and power cable are coiled and properly stowed. DO
NOT allow them to be left casually, in a heap. This invites damage and will
cause rapid deterioration. Take care NOT to drape the hoses/cables over
the hot exhaust. Check to ensure they are fully serviceable.
STORAGE
Fig.11.
Store the Hot Washer preferably under
cover, protected from the elements.
If there is a danger of freezing, the pump
should be filled with antifreeze by inserting
the inlet and outlet hoses into a bucket
of antifreeze as shown in Fig.10. Start the
machine and allow the antifreeze to
circulate. After a short time stop the
machine using the procedure outlined
above, and store the machine with the
antifreeze still within the pump body.
