• For your own safety, do not operate your pressure washer until it is completely
assembled and installed according to the instructions and until you have read and
understood all of the safety guidelines.
Pressure washer safety rules
• Do not force the pressure washer. Use the correct pressure washer for your
application. The correct pressure washer will do the job better and safer at the rate for
which it was designed.
• Do not use the pressure washer if the engine switch or trigger does not turn it on
and off. Any pressure washer that cannot be controlled with the switch is dangerous
and must be repaired.
• Switch off the engine, disconnect the spark plug lead and depressurise unit
before making any adjustments, service or storing pressure washers.
Such preventive safety measures reduce the risk of starting the pressure washer
accidentally.
• Store idle pressure washers out of the reach of children and do not allow
persons unfamiliar with the pressure washer or these instructions to operate the
pressure washer. Pressure washers are dangerous in the hands of untrained users.
• Maintain pressure washers and accessories. Check for misalignment or binding of
moving parts, leakage of water and fuel and any other condition that may affect the
pressure washer’s operation. If damaged, have the pressure washer repaired before
use. Many accidents are caused by poorly maintained pressure washers.
• Use the pressure washer and accessories etc. in accordance with these
instructions, taking into account the working conditions and the work to
be performed. Use of the pressure washer for operations different from those intended
could result in a hazardous situation.
• Keep handles and grasping surfaces dry, clean and free from oil and grease.
Slippery handles and grasping surfaces do not allow for safe handling and control of
the equipment in unexpected situations.
• Do not alter or misuse the tool. These tools are precision built. Any alteration or
modication not specied is misuse and may result in dangerous conditions.
• NEVER leave running equipment unattended. Shut down before leaving worksite.
•ALWAYS release pressure at the end of use.
• NEVER move equipment by pulling the hoses.
• NEVER activate the spray gun with no nozzle in the wand. This will cause the “O”
ring to be dislodged from the coupling and the unit will not function properly.
• NEVER lock the spray gun in the on position.
• NEVER operate with the hose coiled or kinked. Ensure the hose is unwound and as
straight as possible to avoid damage to hose.

10

Additional precautions
Thermal protection valve
CAUTION Before any operator uses this pressure washer
they must understand the pump is tted with a
thermal protection valve.
NEVER allow the pump to run for more than a 3 minute period without operating
the gun. The thermal dump valve is fail safe and pressure will release once the
temperature exceeds the limit. This feature protects the pump from damage. It is
strongly recommended that this feature be used as an emergency safe guard only. Once
released, the pressure washer cannot be used until the thermal dump valve is replaced
by a qualied technician which will not be covered under the warranty.
• Damage caused to the pump due to excessive water temperature will void the
warranty.
• NEVER let the pump run without being connected to a water supply.

12
• NEVER run dirty water through the pump.
• Check the supplied inline lter is connected to the pump inlet, and that it is not clogged
and in good working condition.
• NEVER run caustic (lye) or acidic substances through the pump.
• NEVER use chemical cleaning agents that are not compatible with the Buna-N and
PVC (polyvinyl) or neoprene covering of the hose.
• NEVER run water into the machine more than 60°C .
• ENSURE the water supply into the pump is sufcient, minimum 15lt/min 20psi.
• Before starting the machine be sure the pump is primed & air is purged from the
system by allowing water to ow through the pump.
• When drawing water from a pressure source you need a hose with a 5/8”outside
diameter for lengths up to 15 metres, and 3/4” diameter for lengths up to 30 metres.
Low oil shutdown
The engine is equipped with a low oil shutdown feature and will automatically turn off if
the oil level is below the satisfactory level. This should only be used as an emergency
fail safe. Always check and top up oil to the correct level before use.
Engine precautions
• Use quality fresh Unleaded RON 91 fuel only.
• Use suitable engine oil based on engine manufacturer’s recommendation.
• Ensure oil is lled to the thread on the inlet before use.
Pump oil
• The pump is shipped with correct amount of oil already lled directly from the factory.
The oil should be good for the life of the pump and will not require topping up or
replacement under normal use. Should you need an oil replacement, please contact a
qualied service agent as the pump must be completely removed. Instruction to do this
is not provided as we do not recommend customers doing this.

Adjusting the spray nozzle
Water ow is adjusted by regulating the nozzle. Your pressure washer comes in 5
different colour coded quick connect nozzles that provide spray widths from 0°, 15°, 25°,
40° & a chemical (soap) nozzle. You can simply adjust the spray pattern & pressure by
selecting a different nozzle.
Red Nozzle = 0°
The highest pressure nozzle producing a pencil point pattern with no fan coverage. Ideal
for aggressive cleaning such as removing caked mud from equipment, removing stains
from concrete, steel & aluminium. Not recommended for decks, painted surfaces & cars.
Orange/Yellow Nozzle = 15°
Referred to as a chiseling tip. Narrow fan for high performance. Held at a 45° angle
to the work area it can be used as a chisel or scraper to remove dirt & debris such as
peeled paint or mildew.
Green Nozzle = 25°
Known as the wash tip it has a medium fan for multi-purpose application. It delivers
medium impact pressure and cleaning coverage.
White Nozzle = 40°
With the largest fan area it delivers relatively low pressure ideal for delicate surfaces.
Ideal for washing & rinsing large areas or washing vehicles.
Black Soap Nozzle
This tip is used for chemical / detergent application. It is the lowest pressure nozzle
creating the largest orice.

18
Operation
Pre-operation check
For your safety, to ensure compliance with environmental regulations in Australia, and to
maximize the service life of your equipment, it is very important to take a few moments
before you operate the pressure washer to check its condition. Be sure to take care of
any problem you nd, or have your servicing dealer correct it, before you operate the
engine.
The following pre-start-up inspection must be performed before the start of each work
session and after every four hours of use. If any fault is discovered, the pressure washer
must not be used until the fault is rectied.
1. Thoroughly inspect the pressure washer for signs of damage. Check components are
present and secure.
2. Check for damage, kinks or twists in all lines and hoses before each use. Replace
any damaged hoses.
3. Check the ENGINE oil level and top up if necessary.
4. Check the FUEL level and top up if necessary.
5. Check for fuel and oil leaks.
6. Check the pressure washer is connected to an appropriate water supply - minimum
ow 15lt/min 20psi.
7. Check & tighten all connections.
8. Check the pump is primed & air is purged from lines by squeezing the spray gun
trigger allowing water to ow through the pump. YOU WILL DAMAGE THE PUMP IF
THIS STEP IS NOT PERFORMED BEFORE STARTING THE ENGINE.
Pressure washer start up
!WARNING Before starting up the pressure washer check
that it is receiving water correctly; use of the
appliance without water will damage it. Do not
cover the ventilation grilles when the pressure
washer is in use.
Running the pump dry will cause damage and
void the warranty.
1. Turn on the water supply tap fully.

19
PRESSURE WASHER 3500P
2. Release the safety catch on the gun
3. Squeeze the gun trigger to purge the air for a few seconds and start the engine
according to the operating instructions of the engine manufacturer.
Engine start up
!WARNING During operation the pressure washer must be
positioned on a rm, stable surface.
Start the engine and follow all safety precautions according to the operating instructions
of the engine section in this manual.
Recommended cleaning procedure
1. Hold the spray gun rmly with two hands and a sturdy stance -- Gun kicks back when
triggered.
2. Dissolve dirt by applying the detergent mixed with water to the surface while still dry.
When dealing with vertical surfaces work from the bottom upwards.
3. Leave the detergent to act for 1-2 minutes but do not allow the surface to dry. Starting
from the bottom, use the high pressure jet at a minimum distance of 30 cm. Do not
allow the rinse water to run onto unwashed surfaces.
4. In some cases, scrubbing with brushes is needed to remove dirt. High pressure is not
always the best solution for good cleaning results, since it may damage some
surfaces. The nest adjustable nozzle jet should not be used on delicate or painted
parts, or on pressurised components (e.g. tyres, ination valves, etc.).
5. Effective cleaning depends on both the pressure and volume of the water used, to
the same degree.
6. When not spraying, use the spray gun safety catch/safety lock to prevent accidental
high pressure discharge.
Stop the engine
!WARNING During operation the pressure washer must be
positioned on a rm, stable surface.
