Add Engine Oil
WA NING! Any attempt to crank or start the
engine before being properly serviced with the
recommended oil will result in an engine
failure.
Note: When adding oil to the engine crankcase, use
only high quality detergent oil rated with API service
classification SF,SG, SH or SH/CD rated SAE 30
weight. Select the oils viscosity grade according to
your expected operating temperature:
Do Not Use SAE 10W40 Oil.
Although multi-viscosity oils (5W30, 10W30, etc.)
improve starting in cold weather, these multi-viscosity
oils will result in increased oil consumption when used
above 32°F. Check your engine oil level more
frequently to avoid possible damage from running
low on oil.
To fill unit with oil:
Place pressure washer on a level surface.
Clean area around oil fill and remove oil fill cap
(Figure 4).
Pour oil into the oil fill opening until it reaches point
of overflowing. DO NOT OVERFILL.
Note: The bottle of oil included with your pressure
washer contains more oil than the capacity of the
crankcase.
Install oil fill cap, hand tighten securely.
Note: Check Oil Often During Engine Breakin.
Add Gasoline
DANGE ! Never fill fuel tank indoors. Never
fill fuel tank when engine is running or hot. Do
not smoke when filling fuel tank.
WA NING! Never fill fuel tank completely
full. Fill tank to about 1/2" below the bottom of
the filler neck to provide space for fuel
expansion. Wipe away any fuel spillage from
engine and equipment before starting.
The manufacturer recommends fresh, clean unleaded
automotive gasoline.
Use clean fuel and store in approved containers.
Use clean fill funnels. Never use stale gasoline
left over from last season or gasoline stored for long
periods.

HOW TO USE YOU
P ESSU E WASHE
If you have any problems operating your pressure
washer, please call the pressure washer helpline at
1-800-270-1408.
How to Start Your Engine
The best way to start your engine-powered pressure
washer for the first time is to follow these instructions
step-by-step. This starting information also applies
whenever you start the engine after you have let the
pressure washer sit idle for at least a day.
This pressure washer requires a water source that
flows at least 3.0 gallons per minute. Do not attempt
to siphon water from a non-pressurized container.
Place the pressure washer close enough to an
outside water source so that no more than 50' of
garden hose is needed.
Check that the high pressure hose is tightly
connected to the spray gun and to the pump. See
ASSEMBLY section for illustrations.
Connect the garden hose to water inlet on the
pressure washer pump and turn the water valve on
all the way.
WA NING! Do not run pump without the
water supply connected and turned on. You
must follow this caution or the pump will be
damaged.
Remove dual lance from the spay gun.
Squeeze trigger on spray gun until a steady
stream of water appears.
Apply the safety latch to the spray gun trigger
(Figure 9).
Place the Run/Stop switch to un.
Press the primer bulb 3 times, waiting 2 seconds
between each push
Note: For a warm engine, do not prime.
Grasp rope handle and pull slowly until you feel
some resistance. Then pull cord rapidly to
overcome compression, prevent kickback and start
the engine. Let rope return to starter slowly.
If after 3 pulls the engine fails to start, disengage the
spray gun safety latch, squeeze the trigger to relieve
water pressure, re-engage the spray gun safety latch
and pull the recoil starter handle rapidly (Max. 3
pulls).
How to Stop Your Pressure Washer
Move the Run/Stop switch to Stop.
Simply shutting off the engine will not release
pressure in the system. Squeeze trigger on the
spray gun to relieve pressure in the hose.
Note: A small amount of water will spray out when
you release the pressure.

How to Use the Spray Gun and Dual
Lance
You now should know how to STA T your pressure
washer and how to STOP it. The information in this
section will tell you how to ad ust pressure and apply
chemicals using the spray gun and dual lance.
DANGE ! Never put hands in front of
nozzle.
For most effective cleaning, keep spray nozzle
between 8 to 24 inches away from cleaning
surface.
If you get spray nozzle too close, especially using
high pressure, you may damage the cleaning
surface.
Do not get closer than 6 inches when cleaning
automobile tires.
Applying Detergent
IMPO TANT: Use soaps designed specifically for
pressure washers. Household detergents could
damage the pump.
To apply detergent follow these steps:
Prepare the detergent solution as required by
chemical manufacturer. See chemical bottle for any
instructions

wireform on the handle.
Place small filter end of the chemical in ecting tube
into the detergent container (Figure 10).
CAUTION: Keep the plastic in ector tube
from coming in contact with the hot muffler.
This will damage the plastic tube. When
inserting the filter into a cleaning agent bottle,
route the tube so as to keep it from
inadvertently contacting the hot muffler.
Open the chemical valve handle (Figure 11).
IMPO TANT: Detergent cannot be applied without
the water source turned on.
Make sure garden hose is connected to water inlet.
Check that high pressure hose is connected to
spray gun and pump (see ASSEMBLY section
starting on page 6), and start engine.
Apply detergent to a dry surface, starting from the
bottom and working up to avoid streaking.
Allow the detergent to soak in for 3-5 minutes
before washing and rinsing. Reapply to prevent
surface from drying.
For washing, start at lower portion of area to be
washed and work upward, using long, even,
overlapping strokes.
