SAFETY RULES FOR PRESSURE WASHERS

DANGER: CARBON MONOXIDE

Using a pressure washer indoors CAN KILL YOU IN MINUTES. Pressure washer exhaust contains carbon monoxide (CO). This is a poison gas you cannot see or smell. If you can smell the pressure washer exhaust, you are breathing CO. But even if you cannot smell the exhaust, you could be breathing CO.

NEVER use a pressure washer inside homes, garages, crawlspaces, or other partly enclosed areas.

Deadly levels of carbon monoxide can build up in these areas. Using a fan or opening windows and doors does NOT supply enough fresh air. ONLY use a pressure washer outside and far away from windows, doors, and vents. These openings can pull in pressure washer exhaust.

Even if you use a pressure washer correctly, CO may leak into the home. ALWAYS use a batterypowered or battery-backup CO alarm in the home. If you start to feel sick, dizzy, or weak after the pressure washer has been running, move to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.

WARNING:

The exhaust from this product contains chemicals known to the State of

California to cause cancer, birth defects, or other reproductive harm.

WARNING:

This pressure washer may emit highly flammable and explosive gasoline vapors, which can cause severe burns or even death if ignited. A nearby open flame can lead to explosion even if it isn’t directly in contact with gasoline.

• Do not operate near open flame.

• Do not smoke near pressure washer.

• Always operate on a firm, level surface.

• Always turn pressure washer off before refueling. Allow pressure washer to cool for at least 2 minutes before removing fuel cap. Loosen cap slowly to relieve pressure in tank.

• Do not overfill fuel tank. Gasoline may expand during operation. Do not fill to the top of the tank.

Allow for expansion.

• Always check for spilled fuel before operating.

• Empty fuel tank before storing or transporting the pressure washer.

• Do not allow children or non-qualified persons to operate.

Allow pressure washer to cool down after use before touching the engine or areas of the pressure washer that become hot during operation.

CAUTION:

Misuse of this pressure washer can damage it and shorten its life.

Only use the pressure washer for its intended purposes.

Turn the engine switch to “OFF” position when the engine is not running.

The high pressure stream of water can cut through skin and cause serious injury. Do not aim the stream of water at yourself or at any one else, including animals.

Hoses and tubes can become damaged from coming in contact with a hot engine or muffler. Always double check the hose for perforations before starting up the machine and keep it clear of the engine and the muffler.

Kickback from operation can cause the user to fall down. Always operate the pressure washer on a level and non-elevated surface to prevent the risk of falling.

Always wear safety goggles to protect from possible mishaps with the stream or detergents. Always be aware of the dangers associated with the detergents and chemicals that you are working with.

Attach all hoses before starting the engine.

SAVE THESE INSTRUCTIONS – This manual contains important instructions for the WEN® Pressure

Washer that should be followed during installation and maintenance of the pressure washer.

Pressure washers vibrate in normal use. During and after the use of the pressure washer, inspect both the pressure washer as well as extension and power supply cords for damage resulting from vibration.

Check the oil level of the pressure washer according to the Recommended Maintenance Schedule on page 17. The pressure washer should be checked before each use for proper oil level. This is a critical step for proper engine starting. To check the oil level:

1. Make sure the pressure washer is on a level surface.

2. Clean around oil fill. Remove dipstick and wipe the dipstick with a clean rag. Insert the dipstick into the oil fill opening without screwing in. Remove the dipstick to check the oil mark. Add oil if the oil mark covers less than one half of the dipstick. (Fig. 15)

3. Slowly add more oil and repeat step 2 until the oil mark reaches to the top of dipstick. Do not over fill the crankcase.

4. Reinstall oil dipstick.

CLEANING THE SPARK ARRESTOR

Clean the spark arrestor with a wire brush every 50 hours or 3 months of use. The spark arrestor is the small screen located on the muffler exhaust.

CAUTION:

The muffler is very hot after use. Allow the muffler to cool down completely before cleaning the spark arrestor.

DRAINING THE CARBURETOR

Drain the carburetor after each use to fight fuel deterioration. If you do not drain the carburetor, gasoline will degrade inside the carburetor and clog it, which will make it difficult or impossible to start next time you use it.

18

1. Prepare an approved gasoline-storage container. Position it underneath the carburetor drain screw.

2. Use a screwdriver to loosen and remove the carburetor drain screw. Allow fuel to flow into the container.

3. Once the carburetor has drained, replace the screw.

MAINTENANCE

CHANGING/ADDING OIL (FIG. 16)

Change the oil according to the Recommended

Maintenance Schedule on page 17. Change the oil when the engine is warm to allow for complete drainage.

Change oil more often if operating under heavy load or high ambient temperatures. It is also necessary to drain the oil from the crankcase if it has become contaminated with water or dirt. The oil capacity of the pressure washer engine is 15.3 fl oz (450 ml). Add oil when the oil level is low. For proper type of oil refer to the “add oil” portion of the “Preparation” section.

Oil Drain Plug

Fig. 16

TO CHANGE OIL, FOLLOW STEPS BELOW:

1. Shut off engine. Clean the area around the oil fill cap/dipstick to keep out debris then remove oil dipstick.

2. 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.

3. Once oil is completely drained, return the pressure washer to a level position and install the oil drain plug. Refill the engine with new oil as instructed earlier in this manual under Adding/Checking

Oil.

AIR CLEANER MAINTENANCE

Routine maintenance of the air cleaner helps maintain proper airflow to the carburetor. Occasionally check that the air cleaner is free of excessive dirt. Refer to Recommended Maintenance Schedule on page 17.

1. Unscrew the cover bolt, then remove the air cleaner cover.

2. Remove the air cleaner element from the casing.

3. Check and clean the air cleaner element. Replace with a new one if the element is damaged. A good element can be washed in soapy water and dried. Saturate the element with clean engine oil and squeeze off excess oil.

4. Re-install the element. Wipe off excess oil from the air cleaner housing. A small amount of oil in the element is normal and necessary for the engine to work properly.

5. Reinstall the air cleaner element and cover.

CAUTION:

running the engine with a dirty, damaged or missing air cleaner element will cause the engine to wear out prematurely.

19

MAINTENANCE

DRAINING THE FUEL TANK

Clean fuel tank each year or before storing the pressure washer for extended periods of time. To drain the fuel tank and carburetor:

1. Prepare an approved gasoline-storage container. Turn the fuel valve to the “OFF” position. Position the container so it will catch fuel draining from the carburetor drain screw.

2. Loosen the drain screw until fuel begins to flow out of the carburetor, then turn the fuel valve to the “ON” position. The gas tank will drain through the carburetor.

CAUTION:

Store the emptied gasoline in a safe place. Do not store fuel for more than 3 months.

DRAINING THE SOAP (FIG. 17)

To drain the soap, unplug the hose highlighted in Figure

17 (Fig. 17 - 1). Use a container to hold the draining soap.

Once the soap is done draining, reconnect the hose.

SPARK PLUG MAINTENANCE

The spark plug is important for proper engine operation.

A good spark plug should be intact, free of deposits, and properly gapped. Refer to Recommended Maintenance

Schedule on page 17.

TO INSPECT THE SPARK PLUG (FIG. 18 & 19):

1. Remove spark plug boot (Fig. 18 - 1). Be careful not to tear insulation or wiring.

2. Unscrew the spark plug from the engine using a spark plug wrench. There is limited space for the wrench to turn.

Use both rows of holes in the spark plug wrench to gain leverage to loosen the plug.

3. Visually inspect the spark plug for cracks or excessive electrode wear. Replace as necessary.

4. Measure the plug gap with a wire gauge. The gap should be 0.7-0.8 mm (0.028-0.031 in). (Fig. 19)

5. If re-using the spark plug, use a wire brush to clean any dirt from around the spark plug base then re-gap the spark plug.

6. Screw the spark plug back into the spark plug hole using the spark plug wrench. Do not over-tighten spark plug.

Recommended tightening of spark plug is ½ to ¾ of a turn after the spark plug gasket contacts the spark plug hole, or

15 ft-lb. Reinstall the spark plug boot.

MAINTENANCE

CHECKING DETERGENT SIPHONING TUBE

1. Check the detergent siphoning tube for clogs, leaks, or tears.

2. Make sure the tube fits tightly on the pump fitting.

3. Replace siphoning tube if damaged.

Nozzle Cleaner

HIGH PRESSURE HOSE

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

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

WARNING:

Never repair a high pressure hose or use unit if the hose is damaged. If the hose is damaged. replace it. Contact WEN customer service for assistance.

SPRAY GUN

1. Make sure the spray gun is connected securely.

2. 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. To clean the nozzle:

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

4. Reconnect the nozzle to the spray wand.

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

STORAGE & TRANSPORT

CAUTION:

Never place any type of storage cover on the pressure washer while it is still hot.

If the pressure washer is being stored for short periods of time (30 to 60 days), add stabilized fuel to the fuel tank until full.

NOTE:

Filling the tank reduces the amount of air in the tank and helps reduce deterioration of fuel.

Run the engine for 2 – 3 minutes allowing stabilized fuel mixture to circulate through the carburetor.

STORAGE & TRANSPORT

STORING THE PRESSURE WASHER FOR EXTENDED PERIODS:

1. Drain the fuel tank (see “Draining the Fuel Tank” in the “Maintenance” section).

2. Change oil.

3. Do not obstruct any ventilation openings.

4. Keep the pressure washer in a cool dry area.

TRANSPORTING THE PRESSURE WASHER:

1. Tighten fuel cap. Drain the fuel tank if possible.

2. Always keep the pressure washer upright. Do not lay it down sideways.
