BEFORE STARTING ENGINE
OIL (See Fig. 8A)
Your lawn mower is shipped without oil in the engine.
Be sure mower is level and area around oil fill is clean.
Remove engine oil cap w/dipstick and fill to the full line
on the dipstick.
Use 20 ozs. of oil. For type and grade of oil to use, see
“ENGINE” in Customer Responsibilities section of this
manual.
Pour oil slowly. Do not over fill.
Check oil level before each use. Add oil if needed. Fill
to full line on dipstick.
To read proper level, tighten engine oil cap each time.
Reinstall engine oil cap and tighten.
After the first two (2) hours of mowing, change the oil,
and every 25 hours thereafter. You may need to
change the oil more often under dusty, dirty conditions.
GAS (See Fig. 8A)
Fill gasoline tank with fresh, clean, unleaded gasoline.
DO NOT USE PREMIUM GASOLINE. BE CAREFUL
NOT TO OVER FILL TANK.
WARNING: Experience indicates that alcohol blended
fuels (called gasohol or using 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 emptied before stor-
age of 30 days or longer. Drain the fuel tank, start the
engine and let it run until fuel lines and carburetor are
empty. Use fresh fuel next season. See Storage Instruc-
tions for additional information. Never use engine or
carburetor cleaner products in fuel tank or permanent
damage may occur.
GASOLINE FILL CAP
TO START ENGINE (See Figs. 3, 8A, &
8B)
CAUTION: The mower blade rotates
whenever the engine is running.
RECOIL STARTER
To start a cold engine, push primer three (3) times
before trying to start. Use a firm push. This step is not
usually necessary when starting an engine which has
already run for a few minutes.
Move throttle control lever to fast ( ) position.
Hold operator presence control bar down to the handle
and pull starter handle quickly. Do not allow starter
rope to snap back.
To stop engine, release operator presence control bar.
NOTE: In cooler weather it may be necessary to repeat
priming steps. In warmer weather over priming may cause
flooding and engine will not start. If you do flood engine,
wait a few minutes before attempting to start and do not
repeat priming steps.
