Lubricate O-Rings; High Altitude - Craftsman 580.754930 Operator's Manual

WARNING Fuel and its vapors are extremely
flammable and explosive which could
cause burns, fire or explosion
resulting in death or serious injury.
WHEN ADDING FUEL
o Turn pressure washer engine OFF and let it cool at least
2 minutes before removing fuel cap. Loosen cap slowly to
relieve pressure in tank.
Fitl fuel tank outdoors.
DO NOT overfill tank. Allow space for fuel expansion.
If fuel spills, wait until it evaporates before starting engine.
Keep fuet away from sparks, open flames, pilot lights,
heat, and other ignition sources.
Check fuel lines, tank, cap and fittings frequently for
cracks or leaks. Replace if necessary.
DO NOT light a cigarette or smoke.
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.
CAUTmON! Alcohol-blended fuels {called gasohol,
ethanol or 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.
Lubricate O-Rings
Lubrication of o-rings is extremely important for
installation and operation. The use of a lubricant
(petroleum or synthetic grease) during assembly helps
seat o-rings propedy and provides an improved seal. It
also helps protect the o-ring from damage by abrasion,
pinching or cutting and extends the life of the o-ring.
NOTICE ALWAYS apply a small amount of lubricant
on o-rings prior to assembling the garden hose to the
pump (C), high pressure hose (D), spray gun (E), and
nozzle extension (F).
Lubricate aH connections shown below, following
these instructions:
1 Inspect and clean connecting surfaces prior to
lubrication and assembly.
2 Use lubricants sparingly during assembly; a light
film is aH that is required.
3 Use a small brush or cotton swab to apply grease
directly to o-rings where they are not accessible
(QC fitting, M22 fitting).
