*SPL = Sound Power Level on equipment representative of this type
**GSPL = Guaranteed Sound Power Level for this equipment.
Notes
For the engine to reach it’s maximum power, and the unit to achieve full rated
performance, the machine must be run in for at least 10 hours. The engine’s performance
diminishes as altitude and ambient temperature increase. If the machine is to be used
at altitude or with a high ambient temperature please refer to the engine user manual for
guidance and any necessary precautions.

• The washer has been designed and manufactured for:
- wash down of machinery, vehicles, buildings, facades, tools etc using clean, soft water
at a maximum of 40°C and suitable detergents.
- spraying of disinfectants and/or sanitizing products;
- pumping detergents and colours in aqueous solution;
- pumping water for non-edible use.
• The washer must not be used for pumping:
- aqueous solutions with density and viscosity above that of water;
- solutions of chemical products the compatibility of which with the materials making up
the motor pump itself is not known;
- seawater or water with high salt concentration;
- fuels and lubricants of all kinds and types;
- inflammable liquids or liquefied gases;
- edible liquids;
- solvents and thinners of all kinds and types;
- paints of all kinds and types;
- liquids with temperatures above 40 °C/104 °F or below 5°C/41°F;
- liquids containing granules or solid parts in suspension.
• The washer must not be integrated in machines designed to wash: people, animals,
energized electrical apparatus, delicate objects, the motor pump itself or the machine in
which it is integrated.
• The washer is not designed to operate in environments with special conditions such as,
for example, corrosive or explosive atmospheres.
• The washer is not designed to operate on board vehicles, ships, or planes.
All other uses are to be deemed incorrect.

5. Pre-Operation Set Up
• Unpack and make sure that the Washer is complete and undamaged. If the Washer
appears damaged in any way, do not use the machine and consult your dealer.
• Check engine oil is at correct level as specified in the engine manufacturer’s handbook.
Warning – Engines are not shipped filled with oil
The engine will not start until oil is added. Incorrect engine oil level can result
in serious damage.
• Connect the suction hose & filter assembly (item 10, fig 2) to the inlet feed barb (item 7,
fig 1). Ensure the connection has no air leaks and submerge the filter in water supply
tank. For optimum performance ensure the supply tank is above the Washer to aid
priming and water supply. Ensure the filter is always below the water level.
• Connect the bypass hose (item 11, fig 2) to the bypass outlet on the pressure regulating
valve (item 9, fig 1) and put other end in to the top of the water supply tank.
• Connect the delivery hose (item 12, fig 2) to the delivery outlet (item 8, fig 1).
• Connect the gun and lance assembly (item 13, fig 2) to the delivery hose
• Fit desired quick release nozzle (item 14, fig 2) to the lance assembly outlet. The Washer
is supplied with a selection of nozzles to give different fluid projection.

• When the pump is at a standstill, check
the oil level is not above the notch on the
case and is no more than 2-3mm below it.
Always check the oil when the pump is at a
standstill and has cooled down completely.
Refer to Model Information (page 2) for
type of oil to use.

6. Engine Start Up / Shut Down Procedure
• Consult the accompanying Honda user manual for full engine checks and start up and
shut down procedure
Note – Before starting and after stopping the Washer depress the lance trigger to
release system water pressure.
＊Read and understand the Owner’s Manual before operating the engine.

General Use
• Open and close the lance trigger to start/stop the flow of water as required.
• The washer is fitted with a return-to-tank pressure regulating valve which bypasses
excess fluid back to the supply tank during normal use and when the lance trigger is
closed
NOTE – It is normal for a small amount of water to be bypassing even when the lance
trigger is open.
• The pressure can be adjusted using the pressure adjusting knob (item 6, fig 1) on the
pressure regulating valve.
• The Washer is supplied with a selection of nozzles to give different fluid projection.
Warning – Risk of damage to pump
Do not let the pump idle in bypass for long periods of time. Never leave the
Washer running unattended.

Warning
Stopping the Pump
• Always make sure that, once stop operations have been performed, no part of the motor
pump and of the machine in which it is integrated is moving and no pipes contain liquid
under pressure.
a) Turn off the delivery pressure as described in point a) in “Pump Operation” section.
b) Stop the pump.
c) Wait for the motor pump and the machine in which it is integrated to cool down.
7. Operating Information
Initial Priming
• Ensure the suction filter is fully submerged in the supply tank
• Hold lance trigger open and wait for water to make it’s way up the suction hose and in to
the Washer.
• After initial priming from the water supply tank the Washer is ready to run.
Pump Operation
• The motor pump can only be primed if the pressure of the delivery circuit is reset in the
following way:
a) Fully turn the knob of the regulation valve (item 6, figure 1) anti-clockwise.
b) Start the pump to prime it.
c) Turn the knob (item 6, figure 1) until the water is delivered at the required pressure (turn
clockwise to increase the pressure, turn anti-clockwise to decrease the pressure)

(*) Checks must be more frequent if liquids are used with abrasive particles in suspension.
(**) The oil must be changed whenever the diaphragm is changed.
(***) If very aggressive chemical products are used, the diaphragms are best changed
whatever their condition.
Special Pump Maintenance
