Pre-operation

Adjusting fan pattern

The angle of spray coming out of the lance may be
adjusted on some lances by rotating the nozzle. This will
vary the spray pattern from approximately a 0° narrow
high impact stream to a 60° wide fan spray. (See Figure2).

Trueshopping

www.trueshopping.co.uk

14

A narrow stream has high impact force on the cleaning
surface and results in maximum deep cleaning in a
concentrated area. However, this narrow high impact
spray must be used cautiously, as it may damage some
surfaces.

A wide fan pattern will distribute the impact of the water
over a larger area, resulting in excellent cleaning action
with a reduced risk of surface damage. Large surface
areas can be cleaned more quickly using a wide fan
pattern.

Nozzle cleaning instructions

Trueshopping

www.trueshopping.co.uk

15

A clogged or partially clogged nozzle can cause a
significant reduction of water coming out of the nozzle and
cause the unit to pulsate while spraying. To clean out the
nozzle:

• Turn off and unplug unit.

• Turn off water supply. Relieve any pressure trapped in

the hose by squeezing trigger 2-3 times.

• Separate lance from gun.

• Rotate nozzle to the narrow stream setting. This opens

up the fan blades.

• Using included tip cleaner, or an unfolded paper clip,
insert wire into the nozzle hole and move back and forth
until debris is dislodged. (See Figure 5.)

• Remove additional debris by back-flushing water
through the nozzle. To do this, place end of a garden hose
(with water running) to end of nozzle for 30-60 seconds.

Trueshopping

www.trueshopping.co.uk

16

Angle to the cleaning surface

When spraying water against a surface, maximum impact
is generated when the water strikes the surface “head
on.”

However, this type of impact tends to cause dirt particles
to imbed in the surface, thereby preventing the desired
cleaning action. The optimum angle for spraying water
against a cleaning surface if 45 degrees.

Spraying water against a surface at this angle provides for
the most beneficial impact force combined with efficient
removal of debris from the surface.

Trueshopping

www.trueshopping.co.uk

17

Distance from cleaning surface

Another factor that determines the impact force of the
water is the distance from the spray nozzle to the cleaning
surface. The impact force of the water is increased as the
nozzle is moved closer to the surface.

How to avoid damaging surfaces

Damage to cleaning surfaces occurs because the impact
force of the water exceeds the durability of the surface.
The impact force can be varied by controlling the three
previously noted items. Never use a narrow high impact
stream or a turbo/rotary nozzle on a surface that is
susceptible to damage. Avoid spraying windows with a
narrow high impact stream or turbo nozzle as this may
cause breakage.

The surest way to avoid damaging surfaces is to follow
these steps:

1. Before triggering the gun, adjust the nozzle to a wide
fan pattern.
2．Place the nozzle approximately 4-5 feet from and 45
degrees to the cleaning surface, and trigger the gun.

3. Vary the fan pattern spray angle and the distance to the
cleaning surface until optimum cleaning efficiency is
achieved without damaging the surface.

Trueshopping

www.trueshopping.co.uk

18

Turbo nozzle (Not included with all models)
A turbo nozzle, sometimes referred to as a rotary nozzle,
is a very effective tool that can significantly reduce
cleaning time. The turbo nozzle combines the power of a
narrow high impact stream and the efficiency of a 25
degree fan pattern. This swirls the narrow high impact
stream into a cone shape that cleans a larger area.

CAUTION: Since a turbo nozzle uses a narrow high
impact stream, only use it in applications where the
cleaning surface cannot be damaged by narrow high
impact spray. Additionally, the turbo nozzle is not
adjustable and cannot be used to apply detergent.

Adjustable spray nozzle

Turn off the spray lance first, hold the rear part of spray
nozzle, then turn the front part of spray nozzle clockwise.
Water may be sprayed out from the spray nozzle in fan
shapes (fig 1); turn the front part of spray nozzle
withershins, water may be sprayed out from the spray
nozzle linearly (fig 2).

Trueshopping

www.trueshopping.co.uk

19

Low/high pressure adjustable lance

Using high pressure: Please make sure the trigger is
released and there is not any water spraying. Then turn
the rear part of spray nozzle withershins (fig 4). Squeeze
the trigger, the gun will spray water with high pressure.

Using low pressure: Please make sure the trigger is
released and there is not any water spraying. Then turn
the rear part of spray nozzle clockwise (fig 3). Squeeze
the trigger, the gun will spray water with low pressure.

CAUTION: Selection of high or low pressure by turning
action. The selection of the pressure must be carried out
with the gun in closed position.

Water inlet screen

The water inlet filter must be inspected regularly, so as to
avoid blockage and restriction in the water supply to the
pump (fig 5).

Using detergent

Add detergent to the container. Set the adjustable spray
wand at low pressure position. (fig 6) Trigger gun to spray
detergent.

Detergents

The use of detergents can dramatically reduce cleaning
time and assist in the removal of difficult stains. Some
detergents have been customised for pressure washer
use on specific cleaning tasks. These detergents are
approximately as thick as water.

The use of thicker detergents will clog the chemical
injection system and prevent the application of the
detergent.

Trueshopping

www.trueshopping.co.uk

21

The cleaning power of detergents comes from applying
them to a surface and giving the chemicals time to break
down the dirt and grime. Detergents work best when
applied at low pressure.

The combination of chemical action and high pressure
rinsing is very effective. On vertical surfaces, apply the
detergent starting at the bottom and work your way
upward. This will prevent the detergent from sliding down
and causing streaks. High pressure rinsing should also
progress from the bottom to top. On particularly tough
stains, it may be necessary to use a brush in combination
with detergents and high pressure rinsing.

Operation

The following cleaning procedure will help you to organise
your cleaning task, and ensure that you achieve the most
beneficial results in the shortest amount of time.

Remember to use the spraying/cleaning techniques
previously listed.

Surface preparation

Before starting a pressure wash cleaning job, it is
important to prepare the surface that is to be cleaned.

Trueshopping

www.trueshopping.co.uk

22

This is done by clearing the area of furniture, and making
sure that all windows and doors are closed tight. In
addition, you should make sure that all plants and trees
adjacent to the cleaning area are protected by a drop
cloth. This will ensure that your plants won’t be sprayed
by the detergents.

Initial high pressure rinse

The next step is to spray the cleaning surface with water
to clear off any dirt or grime that may have collected on
the surface. This will allow your detergent to attack the
deep down dirt that has worked its way into the cleaning
surface. Before triggering the gun, adjust the nozzle to a
wide fan pattern and slowly adjust to the desired spray
pattern. This will help you avoid applying too much
concentrated spray to the surface which could cause
damage.

Final rinse

Start final rinse at bottom and work upward. Make sure
you thoroughly rinse the surface and that all detergent
has been removed.

Shut down

1. Be sure all detergent is flushed from system.

2. Turn off motor.

3. Turn off water supply.

4. After motor and water supply are turned off, trigger gun
to depressurise system.

CAUTION: Never turn water supply off before turning
motor off. Serious damage could occur to the pump and/
or motor.

WARNING! Never disconnect high pressure discharge
hose from machine while system is pressurised. To
depressurise, turn motor off, turn water supply off and
squeeze gun trigger 2-3 times.

5. After each use, wipe all surfaces of the pressure
washer with a clean, damp cloth.

Storage

 Do not store pressure washer outdoors.
 Do not store pressure washer where it might

freeze.

Tips for extending the life of your pressure washer.

1. Never operate unit without water.

2. Pressure washer is not meant to pump hot water.
Never connect to hot water supply – this will significantly
reduce life of the pump.

3. Using detergent which is not recommended may cause
damage to pump components (o-rings, etc.).This also
applies to chemicals such as bleach, dish soap, etc.

4. Never operate unit for more than one minute without
spraying water. Resulting heat buildup will damage pump.

5. Before adjusting nozzle’s pressure (high-to-low or
low-to-high) release trigger. Failure to do so will reduce
life of o-rings in lance.
