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 battery-powered 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.

MAINTENANCE & CARE

HIGH ALTITUDE OPERATION

Specific modifications are needed for high-altitude operations. Please contact our customer service line or go to wenproducts.com and search for our high altitude pressure washer kit for important information regarding these modifications. Operating this unit at an altitude over 3000 feet without the proper modifications may increase the engine’s emissions and decrease fuel economy and performance.

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 in Fig. 17. To inspect the spark plug:

1. Remove spark plug boot. Be careful not to tear insulation or wiring.

2. Unscrew the spark plug from the engine using the spark plug wrench provided. 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 with Torch F7RTC spark plug.

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

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. Reinstall the spark plug boot.

CHECKING DETERGENT SIPHONING TUBE

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

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

Nozzle Cleaner

3. Replace siphoning tubes if damaged.

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 with identical part.

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.

MAINTENANCE & CARE

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 PROCEDURES

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.

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.

WARRANTY STATEMENT

Remember to save the receipt. Proof of purchase is required for all warranty work.

WEN® pressure washers are under warranty to be free from defects in materials and workmanship for a period of two (2) years from date of original purchase. Pressure washers used for commercial or rental use have a warranty period of 90 days from date of original purchase. Keep purchase receipt and mail in the product registration card for proof of purchase.

WEN® will repair or replace, at its discretion, any part that is proven to be defective in materials or workmanship under normal use during the two (2) years warranty period. Warranty repairs or replacements will be made without charge for parts or labor. Parts replaced during warranty repairs will be considered as part of the original product and will have the same warranty period as the original product.

To exercise the warranty, DO NOT RETURN TO RETAILER. Instead, call the toll free Customer Service number at (800) 232-1195 and you will be instructed on where to take the pressure washer for warranty service.

Take the pressure washer, the manual, and the proof of purchase (the receipt) to the nearest repair facility recommended by the Customer Service Representative.

To make a claim under this Limited Warranty, you must make sure to keep a copy of your proof of purchase that clearly defines the Date of Purchase (month and year) and the Place of Purchase. Place of purchase must be a direct vendor of Great Lakes Technologies, LLC. Third party vendors such as garage sales, pawn shops, resale shops, or any other secondhand merchant void the warranty included with this product. Contact techsupport@ wenproducts.com or 1-800-232-1195 to make arrangements for repairs and transportation.

When returning a product for warranty service, the shipping charges must be prepaid by the purchaser.

The product must be fully insured with a copy of the warranty card and/or the proof of purchase enclosed. There must also be a description of the problem in order to help our repairs department diagnose and fix the issue. Repairs will be made and the product will be returned and shipped back to the purchaser at no charge.

THIS LIMITED WARRANTY DOES NOT APPLY TO ACCESSORY ITEMS THAT WEAR OUT FROM

REGULAR USAGE OVER TIME INCLUDING BELTS, BRUSHES, BLADES, ETC.

The warranty does not extend to pressure washers damaged or affected by fuel contamination, accidents, neglect, misuse, unauthorized alterations, use in an application for which the product was not designed and any other modifications or abuse. Parts that need regular maintenance such as recoil starters, spark plugs, air filters, etc. are also not covered under the warranty.

WEN® is not liable for any indirect, incidental or consequential damages from the sale or use of this product.

Any implied warranties are limited to two (2) years as stated in this written limited warranty. Some states do not allow the exclusion or limitation of incidental or consequential damages.
