GENERAL TECHNOLOGY

• PSI: Pounds per square inch - Common unit measure used for water
pressure, air pressure, hydraulic pressure and pounds of force.

• LPM: Litres per minute - common unit measure used for flow rate of
water.

• Bypass Mode: In bypass mode, the high pressure pump recirculates
water because the spray gun trigger has not been pressed.

DIESEL ENGINE

1. Air Filter: The air filter prevents airborne contaminants from entering the
engine.

2. Fuel Tank: The fuel tank is a reservoir that holds the diesel fuel.

3. Start Motor: It is powered by the battery and engages the flywheel in
motion to start the engine.

4. Fuel Switch: To turn ‘ON’ or ‘OFF’ the fuel supply to the injection pump.

5. Recoil Starter: Use for starting the engine manually.

6. Decompression Lever: This helps to start the engine by reducing the effort
needed to pull the recoil starter handle.

HIGH PRESSURE WATER PUMP

1. Pump Model & Serial Number: It contains the year, month and day of
production, and can track the batch of materials, assembler and tester.
Please provide the serial no. along with the pump model and version when

SAFETY FEATURES

Bypass mode: In bypass mode, the pump recirculates the water because the

trigger of the spray gun is not being pulled. If the unit is left unused for more
than two minutes, the water temperature will rise to a dangerous level and
could damage internal components of the pump. If this is the case, the
Thermal Relief Valve will automatically engage. If the gun will not be used for a
longer period or the thermal relief valve does not operate, switch off the
engine.

Thermal Relief Valve: In an effort to
prevent damage, pumps are
equipped with a thermal relief valve.
This valve will open when the
temperature inside the pump
becomes too high. The valve will then
release a gush of water in an effort to
lower the temperature inside the
pump. Immediately after this occurs,
the valve will close.

14

Parts & Service: 020 8988 7400 / E-mail: [email protected] or [email protected]

Trigger Safety Switch: The trigger on
the gun has a safety switch to protect
against accidental activation of the
washer. To deactivate the switch,
push the switch down into the trigger.
ALWAYS move the switch back into
the safe up position when not in use
or while being stored.
