Explanation
Washer Pump: Increase the pressure of the water supply.
Engine: Drive the washer pump
High Pressure Water Hose: Carries the pressurized water from the pump to the gun and lance.
Gun: Connects with lance to control water flow rate, direction, and pressure.
Lance: Lance is equipped with a female quick fix-up on the end. This allows the user to quickly change out nozzle for
different spray patterns and change the soap nozzle for the low pressure and chemical/soap applications.
Chemical Hose: Feeds cleaning agents into the pump to mix the pressurized water.
Thermal Relief Valve: In an effort to prevent extreme damage, pumps are equipped with a thermal relief valve. This
valve will open when the temperature inside the pump rises too high. This 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.
Chemical Injection System: Mixes cleaners or cleaning solvents with the pressurized water to improve cleaning
effectiveness.
Water Supply: All pressure washers must have a source of water. The minimum flow rate requirement of water
supply must not fall below 19 LPM (liters per minute) at 20PSI
Pressure Regulator: The pressure setting is preset at the factory to achieve optimum pressure and cleaning. If you
need to lower the pressure, it can be accomplished by these methods. Back away from the surface to be cleaned. The
future away you are, the less the pressure will be on the surface to be cleaned.
By Pass Mode: In bypass Mode, the pump is reticulating water because the trigger of the spray gun is not pulled. If
unit is left in bypass mode for more than two (2) minutes, the water temperature will rise to a dangerous level and
could damage internal components of the pump. Any damage to pump due to these causes will not be covered under
warranty.
Nozzle: The size of the nozzle determines the size of the fan spray and the pressure out of the nozzle. The 0°, 15°,
25°and 40°nozzles are high pressure nozzle, the chemical nozzle 84°is a low pressure nozzle.
0°nozzle – red. This nozzle delivers a pinpoint stream and is extremely powerful. It covers a very small area of
cleaning. This nozzle should only be used on surface that can withstand this high pressure such as metal or concrete.
Do not use on wood
15°nozzle - Yellow. This nozzle delivers a powerful 15 degree spray pattern for intense cleaning of small areas. This
nozzle should only be used on areas that can withstand the high pressure from this nozzle.
25°nozzle - Green. This nozzle delivers a powerful 25 degree spray pattern. This nozzle should only be used on areas
that can withstand the high pressure from this nozzle.


10
40°nozzle - White. This nozzle delivers a 40 degree spray pattern and a less powerful stream of water. It covers a wide
area of cleaning; this nozzle should be used for most general cleaning jobs.
Chemical Nozzle – black. This nozzle is used to apply chemicals or cleaning solutions. It has the least power stream.
Maintenance
Warning: When performing maintenance, you may be exposed to hot surfaces, water pressure, or moving parts that
can cause serious injury or death!
Before performing any maintenance or repair, stop engine and let it cool and release all water pressure. The engine
contains flammable fuel. Do not smoke or work near open flames while performing maintenance.
Nozzle cleaning: If the nozzle becomes clogged with foreign materials, such as dirt, excessive pressure may develop.
If the nozzle becomes partially clogged or restricted, the pump pressure will pulsate. Clean the nozzle immediately
using the nozzle kit supplied.
Wand/Lance:
1. Shut off the pressure washer and turn off the water supply.
2. Disconnect the wand/lance from the gun.
3. Clean the nozzle using the nozzle cleaner provided or a straightened paper clip. Insert into the nozzle end and
work back and forth until obstruction is removed.
4. Direct water supply into nozzle end to back flush loosened particles for 30 seconds.
5. Reconnect wand/lance to gun and turn on water supply.
6. Start pressure washer.
Water Inlet Screen Cleaning:
All pumps are equipped with some type of water filter screen. This screen should be checked periodically and cleaned
if necessary.
1. Remove the filter screen and flush with clean water.
2. Place the cleaned filter screen into the water inlet connector.
Storage
Optimum Winterizing Procedure
1. Drain all water from high pressure washer hose. Roll hose carefully and do not allow hose to be kinked.
2. Drain all water from gun and lance by holding gun in a vertical position with nozzle end pointing down and
squeezing trigger. Store in gun/hose holder.
3. Store chemical hose. High pressure water hose, so they are protected from damage, such as being run over.
It is recommended that you follow these steps to protect the internal seals of the washer pump when storing the unit for
more than 30 days and/or when freezing temperature is expected;
4. Obtain a funnel, 200ml of antifreeze, and approximately 1 meter of garden hose with a male connector attached to
the one end
5. Disconnect spark plug wire
6. Connect the hose to water inlet of pump
7. Add antifreeze to hose.
8. Pull engine starter rope slowly several times. Until antifreeze comes out of high pressure water hose connection
