Operation

WARNING!  Do not operate indoors or in a confined space preventing dangerous carbon

monoxide gas from dissipating.  Carbon monoxide gas is a poisonous, odorless gas that can

cause headache, confusion, fatigue, nausea, fainting, sickness, seizures, or death. If you start to experience any

of these symptoms, IMMEDIATELY get fresh air and seek medical attention.  Never use indoors, in a covered

area, or in a confined space, even if doors and windows are open.  Keep exhaust from this unit from entering a

confined area through windows, doors, vents, or other openings.  When working in areas where vapors could

be inhaled, use a respirator mask according to all of its instructions.

CAUTION! Do not run pressure washer with a damaged hose. Do not run pressure washer without first

connecting and turning on water supply or damage to the pressure washer could result. FAILURE TO

FOLLOW THESE INSTRUCTIONS WILL VOID PRODUCT WARRANTY.

Starting the Pressure Washer

1. Place pressure washer on a level surface.

2. Turn on water.

3. Purge the system’s pump of air by releasing the safety and squeezing the trigger of the spray gun.

4. Attach wand/lance to spray gun.

5. Turn fuel valve to the ON position.

6. Slide the choke lever to the “Choke” position.

7. Turn the engine OFF/ON switch to the “ON” position.

8. Holding the machine with your hand, pull the recoil handle (starter cord) slowly until resistance is felt, then

pull rapidly. Squeeze the Gun trigger and release the pressure after every failed attempt to start the pressure

washer (This will reduce the back pressure).

9. Let engine run for several seconds and then gradually slide the choke lever to the RUN position as the

engine warms up until the choke is fully slid to the RUN position.

WARNING!  Pull cord recoils rapidly and pulls arm towards engine faster than you can let go

which could result in injury.  Always relieve pressure from spray gun before pulling starter cord,

including every failed attempt to start engine.  To avoid recoil, pull starter cord slowly until resistance is felt,

then pull rapidly.

Using the Spray Nozzle

1. To connect or disconnect spray tip, pull back on the quick-connect collar. Insert or remove spray tip then

release collar.

2. When spray tip is connected, pull on the spray tip to make sure it is secured.

3. For general cleaning, use the 40° spray tip. This option is for cement walkways.

4. For stripping, spot cleaning, blasting, and hard to reach areas, use the 25° spray tip. This option is for

removing paint, rust, mildew, marine growth off boats, or grease stains. This option can be used for reaching

second story surfaces, or for the removal of paint, rust, oil stains, tar, gum, and other stubborn substances.

Use extreme caution when using this nozzle.

5. For applying pressure washer safe detergent, use the black soap nozzle.

6. The angle of the nozzles shown indicates the spray “fan shape” projected from the nozzle when the trigger of

the spray gun is pulled, and high-pressure water is passing through the nozzle. The pressure and flow will

not change significantly due to the various fan patterns (Nozzles).

Applying Detergent

1. Rinse surface with cool water before applying cleaner.

2. Prepare detergent as required by job. For best results, follow detergent directions as supplied from

manufacturer.

3. Remove cap from detergent container and fill.

4. Spray detergent on surface. For best results, use long, even, and overlapping strokes. Allow detergent to set

for about 3 minutes before rinsing, but do not allow detergent to dry on surface or it may cause streaking or

cause damage to the surface. Use good judgment.

WARNING! Only use mild, environmentally friendly detergents intended for use in pressure

washers. Ask your specialist dealer about these special products. Never use aggressive

chemicals (e.g. bleach), abrasive detergents or similar to avoid damage to your health, the product and

the environment. Avoid skin contact with detergents, especially contact with eyes! If detergent gets in

your eyes, flush your eyes with clean water and seek immediate medical attention!

Rinsing with the Pressure Washer

1. Test a small area first to avoid surface damage.

2. Rinse from top to bottom using long, overlapping strokes.

Changing the Engine Oil

1. Engine oil will drain better if the engine is still warm, but not hot.

2. Shut off engine.

3. Clean the area around the oil fill cap/dipstick to keep out debris then remove oil fill cap/dipstick.

4. Place an oil pan on the ground to catch oil. Remove oil plug then tilt pressure washer back and to the side to

empty out the oil from the crankcase.

High-Pressure Hose

•

Inspect hose for cuts, bulges, or leaks which can develop from kinking or wear. If damage is found,

immediately replace hose.

•

Inspect couplings for damage. Immediately replace hose if damage is found.

Spray Gun

•

Make sure the spray gun is connected securely.

•

Inspect the spray gun safety and make sure the spray gun trigger springs back upon release.

Spray Nozzle

If a pulsing sensation is felt while squeezing the trigger, the spray nozzle may be dirty or clogged and should be

cleaned immediately.

1. To clean the nozzle, shut off the engine and turn off the water.

2. Remove the nozzle from the spray wand making sure that the nozzle is pointing away from you and in a safe

direction.

3. Use the nozzle cleaner or a small paper clip to

dislodge any foreign materials which are clogging or

restricting the spray tip.

4. Flush debris out of the nozzle by back flushing with a garden hose for 30-60 seconds.

5. Reconnect the nozzle to the spray wand.

6. Turn the water supply back on and start engine.

Checking the Spark Plug

1. Disconnect the spark plug wire from the spark plug.

2. Before removing the spark plug, clean the area around its base to prevent debris from entering the engine.

3. Clean carbon deposits off the electrode with a wire brush.

4. Check the electrode gap and slowly adjust to 0.80mm (0.031in.) if necessary.

5. Reinstall spark plug and tighten to Torque 22.0 – 26.9 Nm (16-20 ft-lb).

6. Reconnect spark plug wire.

7. If spark plug is worn, replace only with an equivalent replacement part. Spark plug should be replaced

annually.

WARNING! Water pressure produced by this unit can cut through skin and tissue leading to

serious injury and possible amputation. Never attempt to repair high pressure hose, always

replace. Never attempt to repair leaks with sealant, always replace O-ring or seal.

Repairing Leaking Connections

Purchase O-Ring / Maintenance kits through your nearest authorised service centre and follow instructions

provided with the kit.

Air Filter

A dirty air filter will reduce the life span of the engine, make starting the engine difficult, and reduce the unit's

performance.

1. To clean, remove the air filter cover.

2. Carefully pull the air filter out by lifting up along the edges.

3. Remove dirt from filter by tapping on it or having it blown out.

4. Reinstall air filter so that it seals and replace air filter cover.

WARNING! Storage cover could be flammable. Let engine cool before covering pressure washer.

Hose Care

•

To extend your hose life, you’ll want to drain the hose after use. Don’t rely on the nozzle to cut the water

when you are done. If you do, the water pressure builds up inside the hose and can burst it. The better

procedure for the hose upkeep is to turn off the water at the spigot and allow the hose to drain.

•

Another way to keep your hose in good shape for longer is to avoid dragging it by the spray trigger

assembly. This weakens the coupler connection and causes leaks.

•

Also, don’t just leave it in a pile when you are finished with it. Using the included hose reel prevents kinks

that create tears.

•

Finally, there is the issue of storing a hose over winter. If you live in a cold winter region, you’ll want to bring

the hose into the garage (or somewhere inside) to prevent freezing. Drain the entire hose first, then coil it on

a hose reel and carry it inside.

Storing the Pressure Washer

If storing pressure washer for 30 days or more follow the procedures below:

1. Add fuel stabilizer to gasoline to keep gasoline from going stale and to prevent gum deposits from forming

on the carburettor. Run engine for a couple of minutes to circulate the fuel stabilizer.

2. Add PumpSaver to protect pump from freezing or damage caused by mineral deposits.

3. Empty fluid from all hoses and pump.

4. Disconnect the spark plug wire and clean the spark plug. Leave spark plug wire disconnected.

5. Clean the air filter.

6. Cover unit with a suitable protective cover to keep unit dry.

7. Store unit in a frost-free area.
