F. Applying detergent
(not available on Predator Plus)
1.
Prepare pressure washer detergent solution as
required by manufacturer.
2.
Place detergent siphon tub/filter into solution.
3.
Adjust double lance to low pressure setting.
4.
Apply cleaning solution to a dry surface, starting
at lower portion of areas to be washed and
work upward, using long overlapping strokes.
5.
Allow time to detergent to activate and then
rinse off. DO NOT allow detergent to dry on.
IMPORTANT
; You must flush the injection system
after each. Place the siphon hose into a bucket of
clean water, then run pressure washer in low pressure
for 2 minutes.
G. Stopping the machine
1.
If using the detergent injector, flush out the
chemical by running clean water through the
system.
2.
Allow machine to run for 1 minute without load
to cool before stopping.
3.
Turn engine ON/OFF switch to OFF
4.
If your machine has a recoil start, pull recoil
start until compression resistance is felt. Store
the machine in this position to help prevent
valve warpage or sticking.
5.
Close fuel valve.
FAILURE TO CLOSE THE FUEL VALVE ON THE ENGINE CAN
CAUSE FUEL LEAKAGE WHEN THE MACHINE IS BEING
TRANSPORTED!
6.
Turn off water supply.
7.
Pull gun trigger to release all pressure in the
system, then LOCK THE TRIGGER.
8.
Hoses may now be disconnected from the
machine.
Failure to release pressure before
disconnecting the hose quick coupler will
result in the quick coupler o-ring seal
blowing out. This o-ring must be
replaced before operating machine.
CARE AND MAINTENANCE:
AFTER EACH USE
If cleaning agents have been mixed with the incoming
water, it is essential to flush the machine with clean
water after use.
If there is a danger of freezing anti-freeze should be
mixed with the flush water or the machine must be
completely drained.
After the final flush stop the machine. DO NOT allow
the machine to idle for more than 15 seconds. This is
particularly important when there is a danger of
freezing. Do not run for longer without water supply.
STORAGE
Store the washer in an upright position, preferably
drained of water if there is a danger of freezing (or fill
with anti-freeze).
PUMP CRANKCASE LUBRICATION
Proper pressure washer pump crankcase lubrication
will help extend the working life of the machine.
Follow these important guidelines. We recommend
keeping a simple service log book.
Change oil in pump after initial 50 hour run-in
period. (SAE 75W-90)
Change pump oil every 3 months, use high
quality oil. (SAE 75W-90)
Pump oil level can be checked with the dip
stick under the breather cap or by viewing the
oil sight gauge where fitted. The oil level is
correct if level is in the centre of the gauge. If
oil level is low, fill to correct level with
recommended oil (SAE 75W-90).
DO NOT
OVERFILL CRANKCASE!
Replace oil in gearbox (separate chamber) with
SAE 90 gear oil every three months.
