Operation (Continued)

sliding down and streaking. Wait a
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.

2a. To rinse or to return the nozzle to

high pressure, release the trigger and
slide the nozzle to the high pressure
setting.

2b. For units with quick connect tips:

replace black 65

tip with another

color tip.

Never make the 
nozzle pressure

adjustment when the gun is triggered.
Adjusting the high-low nozzle when the
gun is triggered can result in damage to
the seals in the nozzle.

Never replace quick 
connect tip when

gun is triggered.

3. After using detergents, flush the suc-

tion system by placing the detergent
suction tube into a bucket of clean
water.

You can control the cleaning power of
your pressure washer in two ways: 

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. 

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.

NOTE:

Some units also may have a reg-

ulator knob on the pump that can
adjust the pressure (if so equipped).

WARNING

NOTICE

5. Cleaning Power

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.

1.  Be sure all detergent is flushed from

system.

2. Turn the engine OFF.

3

Turn the water supply OFF.

4. After the engine and water supply are

turned off, trigger the gun to depres-
surize the system.

NEVER turn the 
water supply off

before turning the engine/motor off.
Serious damage could occur to the pump
and/or engine/motor.

NEVER disconnect 
the high pressure

discharge hose from the machine while
the system is pressurized. To depressurize,
turn engine/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 the pressure washer out-
doors.

Do not store the pressure washer
where it might freeze unless it has
been properly winterized (See page 9,
third column). 

LONG TERM STORAGE INSTRUCTIONS
(MORE THAN 30 DAYS IN STORAGE)

1.  Remove fuel from the tank and run the

pressure washer in a normal operating
mode until the engine stops from a
lack of fuel. Normal operating mode
means actually spraying water from the
gun while the engine is running.

Alternate method 

– Add fuel stabiliz-

er to gas in the tank and run in nor-
mal operating mode for at least five
minutes.

2.  Stop the engine, turn off the water

supply, and trigger the gun to release
pressure in the high-pressure hose.

!

CAUTION

NOTICE

3. Disconnect the water supply and high

pressure hose from the pump.

4. Allow the engine to cool.

5. Disconnect the spark plug wire and

remove the spark plug.

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.

7. Place a rag over the spark plug hole

and slowly pull the starter rope several
times to distribute the oil.

WINTERIZING INSTRUCTIONS 

1.  Follow and complete the Long Term

Storage Instructions on Page 9.

2. Disconnect the spark plug wire.

3. Disconnect the high pressure hose

from the pump.

4. Insert a 12” to 14” piece of garden

hose into the pump inlet.

5. Place a funnel in the other end of the

garden hose.
