Introduction
Congratulations on purchasing your Pressure Washer. We aim to provide quality tools at an
affordable price. We hope you will enjoy using this tool for many years. Your RX450 Portable
Washer has been designed for cars, bikes, boats and other outdoor equipment or garden
patios, green houses etc.
Assembly
You will need a standard screw driver.
1. Insert cable hook hold into the machine (figure 1a)
2. Align holes on the bottom of the pressure cleaner as shown and tighten the 2 screws
(figure 1b)
Figure 1a Figure 1b
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 (Figure2)
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
(figure 3)
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 (figure 4)
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.

Last updated 14/02/2014 Version 1.2 5 | P a g e
Spraying water against a surface at this angle provides for the most beneficial impact force
combined with efficient removal of debris from the surface.
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 recommended way to avoid damaging surfaces is as follows:
-Before triggering the gun, adjust the nozzle to a wide fan pattern.
-Place the nozzle approximately 4-5 feet from and 45 degrees to the cleaning surface,
and trigger the gun.
-Vary the fan pattern spray angle and the distance to the cleaning surface until optimum
cleaning efficiency is achieved without damaging the surface.
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.
Detergents
The use of detergents can dramatically reduce cleaning time and assist in the removal of
difficult stains. Some detergents have been customized for pressure washer use on specific
cleaning tasks. These detergents are approximately as thick as water. The use of thicker
detergents, such as dish soap, will clog the chemical injection system and prevent the
application of the detergent. 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.
The following cleaning procedure will help you to organize 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. This is done by cleaning 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

Last updated 14/02/2014 Version 1.2 6 | P a g e
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.
Detergent Application
USE THE INSTRUCTIONS APPROPRIATE FOR MODEL PURCHASED
NOTE: Use only detergents formulated for pressure washes.
NOTE: Test detergent in an inconspicuous area before use.
For Units with Detergent Applicator Included
Follow manufacturer’s label directions for mixing correct
concentrations of detergent to water ratio through the
pressure washer is approximately 5.4% (1 to 19).
1. Unscrew to top of detergent applicator and fill
applicator with detergent.
2. Replace top on applicator.
3. Remove lance from gun.
4. Attach detergent applicator to gun. (See Figure 8)
5. Apply detergent so it thoroughly covers cleaning
surface. Apply from bottom to top to prevent detergent
from sliding down and streaking.
6. Allow detergent to remain on the surface for a few minutes. This is a good time to use a
brush to lightly scrub heavily soiled areas. Never allow detergent to dry on the cleaning
surface.
7. Remove detergent applicator from gun and replace with the lance, or remove applicator
from end of lance.
8. Rinse detergent from surface.
NOTE: Flush detergent applicator with clear water following each use.
1. Final Rinse
Start final rinse at bottom and work upward. Make sure you thoroughly rinse the surface and
that all detergent has been removed.
2. 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 depressurize 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 pressurized. To depressurize, turn motor off, turn water supply off and squeeze gun
trigger times.

Storage
Do not store pressure washer outdoors or where it might freeze.
Tips for extending the life of your pressure washer;
-Never operate unit without water.
-Pressure washer is not meant to pump hot water. Never connect to hot water supply –
this will significantly reduce life of the pump.
-Using detergent other than others brand may cause damage to pump components (O-
rings, etc.).This also applies to chemicals such as bleach, dish soap, etc.
-Never operate unit for more than one (1) minute without spraying water. Resulting heat
build-up will damage pump.
-Before adjusting nozzles pressure (high-to-low or low-to-high) release trigger. Failure to do
so will reduce life of O-rings in lance.
Maintenance
Nozzle cleaning instructions
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:
1. Turn off and unplug unit.
2. Turn off water supply. Relieve any pressure trapped in
the hose by squeezing trigger 2-3 times.
3. Separate lance from gun.
4. Rotate nozzle to the narrow stream setting. This
opens up the fan blades.
5. 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.)
6. 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.

Electrical safety
WARNING! When using mains-powered equipment, basic safety precautions, including the
following, should always be followed to reduce risk of fire, electric shock, personal injury and material
damage.
The term “power tool" in all of the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
General power tool safety warnings
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and
instructions may result in electric shock, fire and/or serious injury.
1. Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can cause
you to lose control.
2. Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any way.
b) Do not use any adapter plugs with earthed (grounded) power tools.
c) Unmodified plugs and matching outlets will reduce risk of electric shock.
d) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
e) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase
the risk of electric shock.
f) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords
increase the risk of electric shock.
g) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of electric shock.
h) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk of electric shock.
3. Personal safety
a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do
not use a power tool while you are tired or under the influence of drugs, alcohol or medication.
A moment of inattention while operating power tools may result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection. Protective equipment such as
dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off-position before connecting to
power source and/or battery pack, picking up or carrying the tool. Carrying power tools with
your finger on the switch or energising power tools that have the switch on invites accidents.

Last updated 14/02/2014 Version 1.2 11 | P a g e
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of
the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection facilities, ensure
these are connected and properly used. Use of dust collection can reduce dust-related hazards.
4. Power tool use and care
a) Do not force the power tool. Use the correct power tool for your application. The correct power
tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the battery pack from the power tool before
making any adjustments, changing accessories, or storing power tools. Such preventive safety
measures reduce the risk of starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the
power tool or these instructions to operate the power tool. Power tools are dangerous in the
hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and
any other condition that may affect the power tool's operation. If damaged, have the power tool
repaired before use. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking
into account the working conditions and the work to be performed. Use of the power tool for
operations different from those intended could result in a hazardous situation.
5. Service
Have your power tool serviced by a qualified repair person using only identical replacement
parts. This will ensure that the safety of the power tool is maintained.
