DESCRIPTION:
Engine drive high pressure cold water blasters
designed for professional cleaning applicaons.
MATERIAL CONSTRUCTION:
Aussie Scud pressure washers are mounted on heavy
duty trolley mounted frames. They consist of a
quality internal combuson petrol engine driving a
triplex style three piston high pressure pump. The
machines are supplied with wheels for ease of
portability and manoeuvrability. The machines can be
supplied with hose reels and up to 45 metres of high
pressure hose to increase operator convenience.
RISK RANKING METHOD:
Risk is the combinaon of the likelihood of a specic
unwanted event and the potenal consequences if it
should occur.
RISK RANKING TABLE:
The consequences (loss outcomes) are combined
with the likelihood (of those outcomes) in the risk
ranking table to idenfy the risk rank of each loss
event (e.g. a consequence of ‘Moderate’ with a
likelihood of ‘Likely’ yields a risk rank of 17).
The table yields a risk rank from 1 to 25 for each set
of probabilies and consequences. A rank of 25 is
the highest magnitude of risk that is a highly likely,
very serious event.
A rank of 1 represents the lowest magnitude of risk,
an almost impossible very low consequence event.
Controls must be taken to either eliminate or
minimise the risk

ASSEMBLY AND PREPARATION FOR USE
Before proceeding with assembly of your new Aussie
Eco Scud high pressure blaster, check that all parts
listed below are included.
 1 x safety eyewear
 1 x gun handle assembly
 1 x high pressure hose
 1 x dual lance & nozzle assembly
 1 x detergent injector kit
HEAVY DUTY LANCE: To assemble the gun/lance,
screw together and check nozzles have been ed to
end of lance.
A. Machine Preparaon (inial start-up)
1. Check the oil in the pump and gearbox.
Note separate reservoirs. With the machine on
a level surface the oil lever should cover the red
spot in the oil level sight glass on the side of the
machine. If necessary, top up with SAE 75W-90.
Do not mix dierent grades of oil as this may
aect the machines performance. If alternave
oil is used, rst empty out oil by unscrewing
drain plug in boom of machine.
2. Ensure breather plug is ed to pump.
WARNING: Before operaon ensure top
mounted travel plug is replaced by breather
plug. Failure to t breather and keep clean can
result in over pressuring of oil chamber (crank
case) and can blow oil seals. This will void
warranty.
3. Note that the gearbox has a separate oil
reservoir. Gearbox oil is SAE 90 gear oil.
4. Connect baery leads on electric start
machines.
5. Check oil level in engine and ll with proper
grade oil if necessary. (SAE 10W-30 for Honda
engines, check engine manual for other makes)
6. Check fuel level and ll if necessary. (unleaded
petrol)
7. Fit detergent injecon kit to unloader using the
quick coupler (no tools required).

B. Hose Connecons
1. Connect high pressure hose to detergent
injector outlet.
2. If oponal low pressure downstream, in-line
chemical injector is to be used, connect the
injector tube to the detergent inlet and place
the other end of the tube, with the strainer
aached, in the chemical container (not
supplied).
3. Connect gun/lance assembly to high pressure
hose.
4. Check inlet water lter is clean then connect
water supply hose to machine. Use a 25mm
(minimum) hose .
Incoming water supply must deliver double the
ow of the machine. If quesonable, check
supply at machine. If supply is insucient, do
not operate from this outlet. For residenal use,
the outlet closest to the meter will usually
deliver the highest ow rate. Connect only to
clean town water supply.
Warning: Do not operate from tank or pond.
Doing so will cavitate the pump causing
damage. Cavitaon or pump starvaon is not
covered by warranty. Cavitaon is a
phenomenon causing vacuum pockets to form
within the pump that eventually implode under
pressure ping the internal pump surfaces.
Fing instrucons for oponal hose reel
1. Securely clamp the hose reel mounng bar (sold
separately) across the top of the Scud frame
using the two sets of nuts and bolts supplied.
Aussie Pumps recommends using Locte on the
bolts to prevent them vibrang loose.
2. Fit hose reel to the mounng bar using the four
sets of nuts and bolts supplied. Ensure all bolts
are securely ghtened and use Locte to
prevent them vibrang loose. The reel should
be posioned so that it rotates fore/a to aid
ng whip hose.
3. Connect whip hose to high pressure outlet on
pump.
4. Fit handle to reel.
5. Fit gun to hose using C1500.24 nipple.
6. Start up machine (see below) and check for
leaks. All leaks must be reced before using
machine.
C. Before starng the machine
OPERATE IN WELL VENTILATED AREAS ONLY.
1. Ensure machine is level
2. Turn on water supply.
3. Pull gun trigger unl water starts to ow in a
steady steam then release trigger.

F. Applying detergent
(not available on Predator A)
1. Prepare pressure washer detergent soluon as
required by manufacturer.
2. Place detergent siphon tub/lter into soluon.
3. Adjust double lance to low pressure seng.
4. Apply cleaning soluon to a dry surface, starng
at lower poron of areas to be washed and
work upward, using long overlapping strokes.
5. Allow me to detergent to acvate and then
rinse o. DO NOT allow detergent to dry on.
IMPORTANT; You must ush the injecon system
aer 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, ush 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 unl compression resistance is felt. Store
the machine in this posion to help prevent
valve warpage or scking.
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 o 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
disconnecng the hose quick coupler will
result in the quick coupler o-ring seal
blowing out. This o-ring must be
replaced before operang machine.
CARE AND MAINTENANCE:
AFTER EACH USE
If cleaning agents have been mixed with the incoming
water, it is essenal to ush the machine with clean
water aer use.
If there is a danger of freezing an-freeze should be
mixed with the ush water or the machine must be
completely drained.
Aer the nal ush stop the machine. DO NOT allow
the machine to idle for more than 15 seconds. This is
parcularly important when there is a danger of
freezing. Do not run for longer without water supply.
STORAGE
Store the washer in an upright posion, preferably
drained of water if there is a danger of freezing (or ll
with an-freeze).
PUMP CRANKCASE LUBRICATION
Proper pressure washer pump crankcase lubricaon
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 aer inial 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
sck under the breather cap or by viewing the
oil sight gauge where ed. The oil level is
correct if level is in the centre of the gauge. If
oil level is low, ll 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.

A pressure spike will cause the
safety valve to ‘blow’ to prevent
damage to the pump seals.
A pressure spike is generally caused
by the unloader for the following
reasons.
1. Worn nozzles.
Worn nozzles, ed in the end of
the lance, result in less water
bypassing back through the
unloader to cool & lubricate it.
Without sucient ow the
unloader will overheat and wear.
A drop in pressure on the gauge
indicates nozzle wear. Replace
worn nozzles.
2. Dirt in the unloader may cause it
to jam. Clean out unloader &
check inlet lter ed and clean.
3. Leaks in the system can cause
unloader ‘chaer’. This will lead
to the unloader wearing
prematurely. All leaks must be
xed before using the machine.
The safety valve should only be
reset aer checks to ensure the
unloader valve is working correctly.
If in doubt contact, your nearest
Aussie Eco-clean service centre.
The following steps should be taken
to reset the safety valve, with the
unit running.
1. Unscrew the lock nut (C) on the
safety valve and the adjusng
screw (D), should be screwed in
all the way.
2. Using an allen key, loosen the
lock nut (B) on the unloader and
wind the unloader knob (A) in
gradually unl the required
pressure is obtained whilst the
trigger is pulled and water is
running through the pump. Do
not exceed the maximum rated
pressure of the pump.
3. The lock nut (B) should then be
wound down unl it grounds out
at the boom (do not over
ghten as this will further adjust
the pressure) and locked with use
of the allen key. Paint mark across
the nut and knob to idenfy any
tampering with the seng.
4. With the pump running at the
required pressure, the adjusng
screw (D) on the safety valve
should be wound out unl there
is a slight drip. Screw it in one
quarter of a turn, or unl the drip
stops, this will set the safety valve
10% over the required pressure.
The lock nut (C) should then be
locked o. Paint mark to idenfy
any tampering.
5. Repeat running with the trigger
open and then closed two or
three mes to ensure safety valve
doesn’t blow o pressure.
6. If safety valve connues to trip
contact your nearest Aussie Eco-
clean service centre.
This video demonstrates how to
adjust the unloader and the safety
valve (view online on Cold Water
Blaster Spares page)

WEAR PROTECTIVE GOGGLES & CLOTHING!
WARNINGS
OVERSPEEDING
Do not operate machine at over 3200 rpm
(engine speed). Over speeding can cause
serious pump damage.
HIGH PRESSURE SETTING
The high pressure pump is factory set to operate
at its rated pressure. DO NOT ADJUST.
Tampering with the pressure regulator will void
warranty and can be DANGEROUS.
EXCESSIVE BYPASS
Do not run on excessive by-pass. Switch
machine o within ve minutes of ceasing
operaon as excessive by-pass can cause heat
build up in pump and subsequent damage.
Excessive bypass running voids warranty.
CHECK NOZZLE MONTHLY
If pressure drops o check nozzle for wear.
Nozzles should be replaced on a regular basis
(every month for machines in regular use, every
three months for machines used intermiently).
Using the machine with the incorrect nozzle size
or worn nozzle will void warranty and can be
DANGEROUS to the operator.
