Add Fuel
Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane/87 AKI (91 RON). High altitude
use, see High Altitude.
• Gasoline with up to 10% ethanol (gasohol) or up to 15%
MTBE (methyl tertiary butyl ether) is acceptable.
NOTICE Avoid pressure washer damage.
Failure to follow Operator's Manual for fuel
recommendations voids warranty.
• DO NOT use unapproved gasoline such as E85.
• DO NOT mix oil in gasoline.
• DO NOT modify engine to run on alternate fuels.
To protect the fuel system from gum formation, mix in a fuel
stabilizer when adding fuel. See Storage. All fuel is not the
same. If you experience starting or performance problems
after using fuel, switch to a different fuel provider or change
brands. This engine is certified to operate on gasoline. The
emission control system for this engine is EM (Engine
Modifications).
WARNING Fuel and its vapors are extremely
flammable and explosive.
Fire or explosion can cause severe burns
or death.
WHEN ADDING FUEL
• Turn pressure washer OFF and let it cool at least 2 minutes
before removing fuel cap. Loosen cap slowly to relieve pressure
in tank.
• Fill fuel tank outdoors.
• DO NOT overfill tank. Allow space for fuel expansion.
• If fuel spills, wait until it evaporates before starting engine.
• Keep fuel away from sparks, open flames, pilot lights, heat, and
other ignition sources.
• DO NOT light a cigarette or smoke.
1. Clean area around fuel fill cap, remove cap.
2. Slowly add regular unleaded fuel (A) to fuel tank (B). Be
careful not to overfill. To allow for fuel expansion, do not
fill above the bottom of the fuel tank neck.
3. Install fuel cap and wait for any spilled fuel to evaporate.
CAUTION!
methanol) can attract moisture, which leads to separation and
formation of acids during storage. Acidic gas can damage the
fuel system of an engine while in storage.
To avoid engine problems, the fuel system should be treated
with a fuel preserver or emptied before storage of 30 days or
longer. If adding a fuel preserver, fill the fuel tank with fresh
fuel. If only partially filled, air in the tank will promote fuel
deterioration during storage. If fuel preserver is not used,
drain the fuel tank, start the engine and let it run until the fuel
lines and carburetor are empty. Use fresh fuel next season.
See Storage for additional information.
NEVER use engine or carburetor cleaner products in the fuel
tank as permanent damage may occur.
High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum
85 octane / 85 AKI (89 RON) gasoline is acceptable. To
remain emissions compliant, high altitude adjustment is
required. Operation without this adjustment will cause
decreased performance, increased fuel consumption, and
increased emissions. See a qualified Sears dealer for high
altitude adjustment information. Operation of the engine at
altitudes below 2,500 feet (762 meters) with the high altitude
kit is not recommended.
Fresh Start® Fuel Cap
The Fresh Start® fuel cap (C) is designed to hold a
cartridge (D) which contains fuel preserver. Adding fuel
preserver helps keep fuel fresh and carburetors clean for
easier starting all season long. The Fresh Start® fuel cap, if
equipped with a cartridge, automatically drips concentrated
fuel preserver into your fuel tank so you don't have to add it
yourself.
NOTICE Fresh Start® fuel preserver cartridge is available as
an optional accessory, retail item 7133386. It is not included
with the pressure washer. Contact the original equipment
A
manufacturer, retailer, or dealer to obtain a cartridge
B
designed for the Fresh Start® fuel cap installed on this
engine.
Read and follow all instructions and warnings given in the
Fresh Start® fuel preserver cartridge package.
