1. Surface Preparation
The following cleaning procedure will
help you organize your cleaning task and
ensures that you will achieve the best
results in the shortest amount of time.
Remember to use the spraying / cleaning
techniques mentioned in the following
section.
7. Start the engine.
b. Do not exceed 100˚ F (38˚ C) inlet
water temperature.
If the engine is cold, completely close
the engine choke.
NOTE: The inlet water supply must have a
minimum flow rate of 8 gpm (30 lpm).
If the engine is warm, leave the
choke open or just partially closed.
Unlock the trigger safety latch on
the gun. Grasp the starter rope and
brace one foot on the chassis. While
squeezing the trigger on the gun,
pull the starter rope rapidly and
firmly. Continue holding the rope as
it returns. Repeat these steps until
the engine starts. In cool weather,
the choke may have to be kept
closed for 10 to 30 seconds to keep
the engine running. Otherwise,
open the choke as soon as the
engine starts.
4. Turn the water supply ON.
Never run the unit
dry. Be sure the
water supply is completely turned on
before operating the unit.
NOTICE
Before starting a pressure washer clean-
ing job, prepare the surface you intend to
clean. Clear furniture from the area and
make sure that all windows and doors
are closed tightly. Also, protect all plants
and trees near the cleaning area with a
drop cloth. A covering ensures that your
plants won’t be sprayed by the deter-
gents.

8. If the engine does not start after two
or three pulls or if the rope is hard to
pull, squeeze the gun trigger to
release the pressure that has built up
in the high pressure hose. Repeat
Steps 7 and 8 until the engine starts.
1. Check engine oil levels. Add oil as nec-
essary.
NOTE: Some units are equipped with a
low oil sensor that shuts the engine off if
the oil level falls below a certain level. If
the unit stops unexpectedly, check both
the oil and fuel levels. Check the oil level
each time you refuel the unit.
3. Initial High Pressure Rinse
After the engine starts, trigger the gun
3 to 5 times to get any trapped air out
of the system. After the spray becomes
constant, you may need to adjust the
pressure or the spray fan angle for the

Operation (Continued)
If there is not a plastic adjustment knob
located on the pump (See Figure 10),
then the pressure cannot be adjusted.
The only way to adjust the pressure is
to move closer or further away from the
cleaning surface and adjust the spray
fan angle as shown in the next section.
ANGLE TO THE CLEANING SURFACE
When spraying water against a surface,
you can generate maximum impact by
striking the surface head on. However,
this type of impact can cause dirt parti-
cles to embed in the surface and can
prevent the desired cleaning action.
Quick connect tip
Pull back collar
The optimum angle for spraying water
against a cleaning surface is 45 degrees.
Counterclockwise:
Lower pressure
Quick connect tip
Spray water against a surface at a 45
degree angle to achieve the most benefi-
cial impact force and to efficiently
remove debris.

ADJUSTING THE SPRAY FAN ANGLE
A narrow stream has high impact force
on the cleaning surface and results in
maximum deep cleaning in a concen-
trated area. However, this narrow high
impact spray can damage some sur-
faces, so use it cautiously.
Your unit is either equipped with a
adjustable fan nozzle or quick connect
tips that have a range of spray fan
angles.
Figure 15 - Optimum angle to cleaning
surface
If equipped with the adjustable fan
nozzle, the spray end of the lance can
be rotated to have a 0o narrow high
impact stream to a 60o wide fan spray
(See Figure 11).
A wide fan pattern will distribute the
impact of the water over a larger area
resulting in excellent cleaning action
with reduced risk of surface damage.
Clean large surface areas quickly using
a wide fan pattern.
DISTANCE FROM CLEANING SURFACE
The distance between the spray nozzle
and the cleaning surface is another fac-
tor that affects the impact force of the
water. The impact force of the water
increases as the nozzle is moved closer to
the surface.
Nozzle
HOW TO AVOID DAMAGING SURFACES
Damage to cleaning surfaces occurs
because the impact force of the water
exceeds the durability of the surface. You
can vary the impact force by controlling
the nozzle’s fan pattern, the nozzle’s
angle to the cleaning surface, and the
nozzle’s distance from the cleaning sur-
face. Never use a narrow high impact
stream or a Turbo/rotary nozzle on a sur-
face that is susceptible to damage. Avoid
spraying windows with a narrow high
impact stream or turbo nozzle. Doing so
may break the window. The most sure
way to avoid damaging surfaces is to fol-
low these steps:
Figure 11 - Adjusting nozzle for fan
pattern
Figure 13 - Narrow high impact stream
If equipped with the quick connect tips,
the tips can be switched out from a 0o
narrow high impact stream to a 65o
wide fan spray.
The color of the tip shows what spray
angle it is:

Yellow – 15o – Heavy Duty

that turns from left to right). Pull
firmly and quickly away from you.
(NOTE: Do not adjust lance while
spraying.) The lance will extend
1/2” and be in low pressure (See
Figure 18). Soap can only be drawn
in low pressure.
Once applied to a cleaning surface, deter-
gents take time to break down dirt and
grime. Detergents work best when
applied at low pressure.
2. Place the nozzle approximately 4-5
feet away from the cleaning surface.
Then hold the nozzle at a 45 degree
angle to the cleaning surface. Trigger
the gun.
You can effectively clean surfaces by com-
bining the chemical action of detergents
with high pressure rinses. On vertical sur-
faces, apply the detergent starting at the
bottom and work your way upward. This
method prevents the detergent from slid-
ing down and causing streaks. Begin high
pressure rinsing at the bottom and work
your way upward. On particularly tough
stains, use a brush in combination with
detergents and high pressure rinsing.
3b.For units with quick connect tips:
use the black 65o quick connect
spray tip (See Figure 16).
3. Vary the fan pattern spray angle and
the distance to the cleaning surface
until optimum cleaning efficiency is
achieved without damaging the sur-
face.
4. If equipped, adjust the detergent
injection flow by turning the collar
of the injector. Turning collar clock-
wise decreases flow of detergent
and turning collar counter clock-
wise increases detergent flow (See
Figure 17).
TURBO NOZZLE (NOT INCLUDED WITH
ALL MODELS)
A turbo nozzle, sometimes referred to as
a rotary nozzle, can significantly reduce
cleaning time. The turbo nozzle combines
the power of a narrow high impact
stream with the efficiency of a 25 degree
fan pattern. The turbo nozzle swirls a nar-
row high impact stream into a cone
shape to clean a larger area.
1. Follow manufacturer’s label direc-
tions for mixing correct concentra-
tions of soap/detergents. The soap
detergent to water ratio through
the pump is approximately 10% (1
to 10).
2. Insert the filter end of the clear plas-
tic detergent tube into the deter-
gent container.
Since a turbo nozzle
uses a narrow high
NOTICE
impact stream, only use a turbo lance in
applications where the cleaning surface
cannot be damaged by narrow high
impact spray. 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. Many deter-
gents are customized for pressure washer
use on specific cleaning tasks. Pressure
washer detergents are as thick as water.

couple of minutes for the detergent
to break down the dirt and grime.
Use a brush to lightly scrub heavily
soiled areas. Never allow the deter-
gent to dry on the cleaning surface.
6. Final Rinse
PRESSURE RELIEF
PROCEDURE
The final rinse should start at the bottom
and work upward. Make sure that you
thoroughly rinse the surface and that you
remove all detergent.
To reduce the risk of bodily
injury or property damage,
always follow this procedure

5. Cleaning Power
5. After each use, wipe all surfaces of the
pressure washer with a clean, damp
cloth.
3. Disconnect the water supply and high
pressure hose from the pump.
You can control the cleaning power of
your pressure washer in two ways:
•
Do not store the pressure washer out-
doors.
4. Allow the engine to cool.
1. Adjust the spray pattern at the noz-
zle. Choose the widest pattern possi-
ble for spraying when starting the
job and adjust the pattern to a nar-
rower angle until you find a suitable
pattern.
5. Disconnect the spark plug wire and
remove the spark plug.
•
Do not store the pressure washer
where it might freeze unless it has
been properly winterized (See page 9,
third column).
6. Pour 1/2 oz. of engine oil into the
spark plug hole.
Never pull the
starter rope on the
engine when the spark plug is removed
unless the spark plug hole is covered. Fuel
vapor from the hole can ignite by a spark.
!
WARNING
2. The easiest way to regulate the
cleaning power of your pressure
washer is by changing the distance
from the surface you are cleaning.
Begin spraying with a wide fan pat-
tern while standing several feet from
the surface. Slowly move closer to the
object you are cleaning, adjusting the
spray pattern as necessary, until you
find the most effective cleaning tech-
nique.
8. Storage
