ASSEMBLY AND PREPARATION FOR USE

Before proceeding with assembly of your new Aussie Eco AB high pressure blaster, check that all parts listed
below are included.

1 Gun handle assembly and high pressure hose
1 Lance and nozzle assembly

A. Machine Preparation (initial 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
different grades of oil as this may affect the machines performance.
If alternative oil is used, first empty out oil by unscrewing drain plug
in bottom of machine.

2. Ensure breather plug is fitted to pump.
WARNING: Before operation ensure top mounted travel plug is
replaced by breather plug. Failure to fit breather and keep clean can
result in over pressuring of oil chamber (crank case) and can blo w 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 battery leads on electric start machines.

5. Check oil level in engine and fill with proper grade oil if necessary.
(SAE 10W-30 for Honda engines, check engine manual for other
makes)

6. Check fuel level and fill if necessary. (unleaded petrol)

7. Assemble gun/lance assembly.

HEAVY DUTY LANCE: To assemble the lance, insert Section B into Section A and screw together and check
nozzles have been fitted to end of lance (C & D).

B. Hose Connections

1. Connect high pressure hose to machine outlet.

2. If optional 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 attached, in the chemical
container (not supplied).

3. Connect gun/lance assembly to high pressure hose.

4. Check inlet water filter is clean then connect water supply hose to machine. Use a 25mm (minimum)
hose .

Incoming water supply must deliver double the flow of the machine. If questionable, check supply at
machine. If supply is insufficient, do not operate from this outlet. For residential use, the outlet closest to
the meter will usually deliver the highest flow rate. Connect only to clean town water supply.

Warning: Do not operate from tank or pond. Doing so will cavitate the pump causing damage. Cavitation
or pump starvation is not covered by warranty. Cavitation is a phenomenon causing vacuum pockets to
form within the pump that eventually implode under pressure pitting the internal pump surfaces.

Fitting instructions for optional hose reel

, Securely clamp the hose reel mounting bar across the top of the Scud

frame using the two sets of nuts and bolts supplied. Aussie Pumps
recommends using Loctite on the bolts to prevent them vibrating loose.

, Fit hose reel to the mounting bar using the four sets of nuts and bolts

supplied. Ensure all bolts are securely tightened and use Loctite to
prevent them vibrating loose.

The reel should be positioned so that it rotates fore/aft to aid fitting
whip hose.

, Connect whip hose to high pressure outlet on pump.
, Fit handle to reel.
, Fit gun to hose using C1500.24 nipple.

Start up machine (see below) and check for leaks. All leaks must be
rectified before using machine.

C. Before starting the machine

OPERATE IN WELL VENTILATED AREAS ONLY.

1. Ensure machine is level

2. Turn on water supply.

3. Pull gun trigger until water starts to flow in a steady steam then release trigger.

D. Starting the engine (for Honda , refer to engine manual for other engine options)

1. Ensure fuel valve is open

2. Move the choke on the engine to the closed position (see fig. 1). If engine is warm, move choke half-way.

3. Turn engine ON/OFF switch to ON

4. Hold the gun trigger on.

5. Start engine, either turn engine key or pull the recoil starter grip lightly until resistance is felt, then pull
briskly.

6. After engine starts, release the gun trigger and slowly open the choke.

7. Warm up engine for 3 minutes without load.
