Equipment Operation
WARNING
CAUTION
Do not direct spray
from the pressure
washer at a person or an
animal. The water stream
could cause serious injury.
Use the pressure
washer only on
surfaces able to withstand the
force of the spray.
Replace the non-vented brass oil 1.
plug with the aluminum Pump Breath-
er Plug before rst use. The Pump
Breather Plug must be used whenever the pressure washer is used. The
brass oil plug (without the breather
hole) should be used for transporting
only.
Choose the Nozzle that best meets 2.
the needs of the job. Only use the
Nozzles on surfaces capable of withstanding the force of the spray. Only
use the Black Nozzle when using
pressure washer detergent. The
power of the other Nozzles will
propel mist back at the operator
and can imbed detergent into the
surface.
Pull back the quick connect collar and 3.
push the Nozzle onto the end of the
Wand. Make sure the quick connect
collar locks the Nozzle in place.
Turn the water supply on and hold 4.
down the Trigger to start the stream.
Be aware that when it is rst started,
the gun will kick.
It is best to start at a low pressure 5.
setting, and adjust the pressure
upwards. Test spray the edge
of the surface to be cleaned rst
to make sure that the stream is
not too strong for the surface. If
the stream damages the surface
turn the Pressure Regulator Knob
counterclockwise to reduce the
pressure. Moving further away from
the surface being cleaned will also
reduce the pressure being applied
to the surface. If the stream is still
too strong. Turn the engine off, turn
the water supply off, discharge the
excess pressure from the gun by
squeezing the Trigger, and change to
a lower pressure Nozzle.
To increase the pressure, turn the 6.
Pressure Regulator Knob clockwise.
Page 15For technical questions, please call 1-800-444-3353.SKU 67596
Page 16
Hold the Wand at about a 45° 7.
angle when cleaning; spraying the
surface directly could embed dirt
into the surface (especially with the
high pressure Nozzles). Spray at a
distance of about three to ve feet.
Clean vertical and sloped surfaces •
from the top down.
When cleaning horizontal surfaces, •
occasionally use the stream to clear
the area of excess water.
CAUTION Do not allow the Pressure
Washer to idle, without the Trigger held down, for more than two
minutes. The water will heat up
and damage the Pressure Washer.
RISK OF BURNS!
The pump will also expel very hot
water if allowed to idle too long.
Hold the Trigger down and move 8.
the Wand back and forth slowly
and steadily to pressure wash the
surface. Take special care when
spraying surfaces made of two
different materials (brick and mortar,
for example), to not damage the
softer of the two materials during
pressure washing.
If the surface is streaked or uneven 9.
at the end of a job, switch to a Nozzle

Air Filter Element Maintenance
Spark Plug Maintenance
The air cleaner cover is held in place 1.
by a wing nut or clamps. Remove it.
Remove the air lter element.2.
Cleaning:3.
For “paper” lter elements: a.
To prevent injury from dust and
debris, wear ANSI-approved safety
goggles, NIOSH-approved dust
mask/respirator, and heavy-duty
work gloves. In a well-ventilated
area away from bystanders, use
pressurized air to blow dust out of
the air lter.
If this does not get the lter
reasonably clean, replace it.
For foam lter elements: b.
Wash the element in warm water
and mild detergent several times.
Rinse. Squeeze out excess water
and allow it to dry completely. Soak
the lter in lightweight oil briey, then
squeeze out the excess oil.
Install the new lter or the cleaned 4.
lter. Secure the Air Cleaner Cover
before use.
Disconnect spark plug wire from 1.
end of plug. Clean out debris from
around spark plug.
Using a spark plug wrench, remove 2.
the spark plug.
Inspect the spark plug: 3.
If the electrode is oily, clean it using a
clean, dry rag.
If the electrode has deposits on it,
polish it using emery paper.
If the white insulator is cracked or
chipped, the spark plug needs to be
replaced.
When installing a new spark 4.
plug, adjust the plug’s gap to the
specication on the Technical
specication chart. Do not pry
against the electrode, the spark plug
can be damaged.
Install the new spark plug or the 5.
cleaned spark plug into the engine.
Gasket-style: Finger-tighten until the
gasket contacts the cylinder head,
then about 1/2-2/3 turn more.
Non-gasket-style: Finger-tighten until
the plug contacts the head, then
about 1/16 turn more.
Apply dielectric spark plug boot 6.
protector (not included) to the end of
the spark plug and reattach the wire
securely.

Fuel Filter Replacement (if equipped)
WARNING! RISK OF FIRE
OR EXPLOSION. Replace the
fuel lter in a well-ventilated
area away from ignition
sources. Do not smoke.
Wait for engine to cool completely 1.
before proceeding.
Wear protective gear including, ANSI-2.
approved safety goggles, NIOSHapproved dust mask/respirator, and
nitrile gloves.
Close fuel valve leading from gas 3.
tank completely.
Take note of the fuel lter’s 4.
orientation.
Cleaning, Maintenance, and
Lubrication Schedule
Note: This maintenance schedule
is intended solely as a general
guide. If performance decreases
or if equipment operates unusually,
check systems immediately. The
maintenance needs of each piece
of equipment will differ depending
on factors such as duty cycle,
temperature, air quality, fuel quality,
and other factors.
Note: These procedures are in addition to
the regular checks and maintenance
explained as part of the regular
operation of the engine and
equipment.
Place a suitable container under the 5.
fuel lter.
Disconnect the fuel lines leading to 6.
and from the fuel lter and allow fuel
to drain onto the container.
Install new fuel lter in the same 7.
orientation. Make sure to properly
secure both fuel lines.
Clean up and properly dispose of all 8.
fuel.
Wait for at least one hour before use 9.
to allow all residual fuel vapors to
dissipate. To prevent FIRE, do not
start the engine while the smell of
fuel hangs in the air. Remember to
open the fuel valve before restarting
the engine. It may take a little
longer than usual to start the engine
because the fuel needs to rell the
fuel line and new lter.
After 20 Operation Hour Break-in

the product or part must be returned to us
with transportation charges prepaid. Proof
of purchase date and an explanation of the
complaint must accompany the merchandise.
If our inspection veries the defect, we will
either repair or replace the product at our
