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 oils 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 Breakin.

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.

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.
