Equipment Operation
Do not direct spray
from the pressure
washer at a person or an
animal. The water stream
could cause serious injury.
3.
Pull back the quick connect collar and
push the Nozzle onto the end of the
Wand. Make sure the quick connect
collar locks the Nozzle in place.
4.
Turn the water supply on and hold
down the Trigger to start the stream.
Be aware that when it is first started,
the gun will kick.
5.
It is best to start at a low pressure
setting, and adjust the pressure
upwards. Test spray the edge
of the surface to be cleaned first
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.
6.
To increase the pressure, turn the
Pressure Regulator Knob clockwise.
WARNING
Caution
Use the pressure
washer only on
surfaces able to withstand the
force of the spray.
1.
Replace the non-vented brass oil
plug with the aluminum Pump Breather Plug before first 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.
2.
Choose the Nozzle that best meets
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.

For technical questions, please call 1-800-444-3353.
Page 15
7.
Hold the Wand at about a 45°
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 five 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.
8.
Hold the Trigger down and move
the Wand back and forth slowly

2.
Remove the air filter element.
Disconnect spark plug wire from
end of plug. Clean out debris from
around spark plug.
3.
Cleaning:
2.
Using a spark plug wrench, remove
the spark plug.
3.
Inspect the spark plug:
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.
4.
When installing a new spark
plug, adjust the plug’s gap to the
specification on the Technical
specification chart. Do not pry
against the electrode, the spark plug
can be damaged.
5.
Install the new spark plug or the
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.
6.
Apply dielectric spark plug boot
protector (not included) to the end of
the spark plug and reattach the wire
securely.
a.For “paper” filter elements:
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 filter.
If this does not get the filter
reasonably clean, replace it.
b.For foam filter elements:
Wash the element in warm water
and mild detergent several times.
Rinse. Squeeze out excess water
and allow it to dry completely. Soak
the filter in lightweight oil briefly, then
squeeze out the excess oil.
4.
Install the new filter or the cleaned
filter. Secure the Air Cleaner Cover
before use.

Fuel Filter Replacement (if equipped)
WARNING! Risk of fire
or explosion. Replace the
fuel filter in a well-ventilated
area away from ignition
sources. Do not smoke.
1.
Wait for engine to cool completely
before proceeding.
2.
Wear protective gear including, ANSIapproved safety goggles, NIOSHapproved dust mask/respirator, and
nitrile gloves.
3.
Close fuel valve leading from gas
tank completely.
4.
Take note of the fuel filter’s
orientation.
5.
Place a suitable container under the
fuel filter.
6.
Disconnect the fuel lines leading to
and from the fuel filter and allow fuel
to drain onto the container.
7.
8.
9.
Install new fuel filter in the same
orientation. Make sure to properly
secure both fuel lines.
Clean up and properly dispose of all
fuel.
Wait for at least one hour before use
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 refill the
fuel line and new filter.

PRESSURE WASHER Easy Start-up guide
1. Remove Pump Oil Cap, check Pump’s oil level and add SAE 30W oil if low. Replace with Pump Breather Plug. (Figure 1)
Running without the pump breather plug can cause pump damage. (See oil fill instructions in manual or on product label.)
2. Check Dipstick for Engine oil level (Figure 2 A). Fill Engine with proper amount of oil if dipstick indicates
low oil (Figure 2 B). Use SAE 10W-30 oil for air temperature of 32° F or above, SAE 5W-30 below 32° F.
Fill Fuel Tank with 89 or higher octane unleaded gas mixed with fuel stabilizer (not included).
3. Connect and turn on water supply. Turn the pressure regulator counterclockwise to lower the output pressure.
Point Spray Nozzle in safe direction and squeeze trigger to release all pressure from the pump.
4. Turn the red ignition switch to ON position (Figure 4).
5. Turn the Fuel Valve Lever (Gas pump symbol) to its OPEN position (Figure 5).
6. Set Throttle to slow (turtle symbol) and turn the engine choke lever to its CHOKE position
for cold start. Set the choke lever in the 1/2 CHOKE position when starting a warm engine (Figure 5).
7. Grasp the starter handle, and pull slowly until resistance is felt (Figure 6). While holding the handle, allow the starter rope to rewind
slowly. Then, pull the starter handle with a rapid, full arm stroke. Once again while holding the handle, allow the rope to rewind slowly.
Repeat as needed until the engine starts.
8. After the Engine starts and warms up, slowly move the Choke Lever to its RUN position (Figure 5).
IMPORTANT: Allow the Engine to run at no load, low pressure for five minutes after each start-up so Engine can stabilize.
9. Move the throttle up to operating speed (Fast) except during OPERATIONAL break-in period (Figure 5).
Turn the pressure regulator clockwise to raise the output pressure as needed.
