Pressure Washer
! IMPORTANT !
This pressure washer is equipped with a microswitch sensitive to water flow. This Instant
Start/Stop switch (ISS) senses water flow in the pump. When the trigger is released,
water stops flowing through the pump. The ISS then automatically turns the motor off
to protect pump from overheating.
OPERATION
1. Pull trigger on gun.
2. Turn the “ON/OFF” switch to “ON”.
3. Release trigger. The pressure washer motor will stop running.
4. To spray again, pull trigger and motor and pump will restart.
Note: Occasionally the motor may run for a short time to bring fresh, cool water into
the pump even if trigger is released. This is part of normal operation and will not damage
the unit.
Risk of Injection.
Unit will start spraying when trigger is squeezed if ON/OFF switch is in “ON”
position. Always point gun in safe direction.
Always turn the “ON/OFF” switch to “OFF”, then trigger gun to

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 Figure
2).
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
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 un-folded
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.

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 is 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.
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 SURFACE
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.
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 break down the dirt and grime.
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 the 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.
Before starting a pressure washer 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
adjacent to the cleaning area are protected
by a drop cloth. This will ensure that your
plants won’t be sprayed by the detergents.
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.
NOTE: Use only detergents formulated for
pressure washers.
NOTE: Test detergent in an inconspicuous
area before use.
Follow manufacturer’s label directions for
mixing correct concentrations of soap/
detergents. The soap/detergent to water ratio
through the pressure washer is approximately
5.4%.
1. Unscrew 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 throughly 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.
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.
Start final rinse at bottom and work upward.
Make sure you throughly rinse the surface and
that all detergent has been removed.
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.

NEVER turn water supply
off before turning motor off. Serious
damage could occur to the pump and/or
motor.
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 2-3
times.
5. After each use, wipe all surfaces of the
pressure washer with a clean, damp cloth.
•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 detergents other than foreseen for
pressure washer brand may cause
damage to pump components (o-rings,
seals, etc). This also applies to chemicals
such as bleach, dish soap, etc.
4. Never operate unit for more than one (1)
minute without spraying water. Resulting
heat buildup will damage pump.
5. Before adjusting nozzle for pressure
(high-to-low or low-to-high) release trigger.
Failure to do so will reduce life of o-rings
in lance.
