Use fresh (within 30 days from purchase), lead-free gasoline with a
minimum of 87 octane rating. Do not mix oil with gasoline.
To add gasoline, follow these steps: (Fig. 7)
1. Make sure the pressure washer is on a level surface.
2. Unscrew fuel cap (Fig. 7 - 1) and set aside.
NOTE: The fuel cap may be tight and hard to unscrew.
3. Slowly add unleaded gasoline to the fuel tank (Fig. 7 - 2). Be care-
ful not to overfill. The capacity of the fuel tank is 0.9 gallons.
NOTE: Do not fill the fuel tank to the very top. Gasoline will expand
and spill over during use even with the fuel cap in place.
4. Reinstall fuel cap and wipe clean any spilled gasoline with a dry
cloth.
IMPORTANT:
• Never use an oil/gasoline mixture.
• Only use unleaded gasoline.
• Never use old gasoline.
• Avoid getting dirt or water into the fuel tank.
• Gasoline can age in the tank and make starting difficult. Never store pressure washer for extended periods of time
with fuel in the tank.
HIGH ALTITUDE OPERATION ABOVE 2000 FEET
The fuel system on this pressure washer may be affected by operation at high altitudes. Proper operation can be
ensured by installing an altitude kit at altitudes higher than 2000 feet above sea level. At elevations above 7000 feet,
the engine may experience a decrease in performance, even with the proper altitude kit. Operating this pressure
washer without said kit may increase the engine’s emissions and decrease both fuel economy and performance.
You can order the kit at wenproducts.com by searching part no. PW3400-HA27. This kit should be installed by a
qualified mechanic. Refer to the instructions included with your altitude kit for more information about installation.
ADDING GASOLINE
ASSEMBLY & ADJUSTMENTS
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 not directly in
contact with gasoline.
WARNING! To prevent serious injury from fire, follow the kit installation procedures in a well-ventilated area
away from ignition sources. If the engine is hot from use, shut the engine off and let it cool before proceeding.
Do not smoke near the pressure washer. Warranty will be void if adjustments are not made for high altitude use.
CAUTION! Operating engines at lower altitudes with the high-altitude kit installed could cause severe engine
damage and affect emissions compliance. Be sure to uninstall the high altitude kit when operating at altitudes
below 2000 feet.
