OPERATION
BEFORE STARTING ENGINE
ADD OIL (See Figs. 14 and 15)
Your lawnmower is shipped without oil in the engine. For type
and grade of oil to use, see “EN GINE” in the Maintenance
section of this manual.
CAUTION: DO NOT overfi ll engine with
oil, or it will smoke heavily from the muf-
er on startup.
1. Be sure lawnmower is level.
2. Remove oil dipstick from oil fi ll spout.
3. Engine holds 18.5 ounces of oil. For type and grade
of oil to use, see “ENGINE” in the Maintenance section
of this manual.
4. Pour oil slowly. Do not overfi ll. Wait one minute to al-
low oil to settle. Use guage on oil fi ll cap/dipstick for
checking level. Insert dipstick into the tube and rest
the oil fi ll cap on the tube. DO NOT thread the cap into
the tube when taking reading.
5. Always be sure to tighten dipstick before starting engine.
IMPORTANT:
• Check oil level before each use. Add oil if needed. Fill

Change the oil after every 25 hours of operation or each
season. You may need to change the oil more often
under dusty, dirty conditions. See “TO CHANGE EN-
GINE OIL” in the Maintenance section of this manual.
ADD GASOLINE (See Fig. 15)
• Fill fuel tank to bottom of tank fi ller neck. Do not over-
fi ll. Use fresh, clean, regular unleaded gasoline with
a minimum of 87 octane. Do not mix oil with gasoline.
Purchase fuel in quan ti ties that can be used within 30
days to assure fuel freshness.
CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open fl ame.
Alcohol blended fuels (called gasohol
or using ethanol or methanol) can at-
tract moisture which leads to separation
and for ma tion of acids during storage.
Acidic gas can damage the fuel sys-
tem of an engine while in storage. To
avoid engine problems, the fuel system
should be emptied before stor age of
30 days or longer. Empty the gas tank,
start the engine and let it run until the
fuel lines and carburetor are empty. Use
fresh fuel next season. See Storage
In struc tions for additional information.
Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.
