moving parts have come to a complete stop°
Disconnect the spark plug wire and secure it away
from the sparkplug.
NOTE: Although multi-viscosity oils (5W30, 10W30,
etc), improve starting in cold weather, these multi-
viscosity oils will result in increased oil consumption
when used above 32°F. Check your engine oil level
more frequently to avoid possible engine damage from
running low on oil,
3, With the machine on level ground, remove the
dipstick (A, Figure 18) and place it on a clean surface.
4, Using a clean funnel, slowly add oil to the dipstick
hole. While adding oil, frequently reinstall dipstick (screw
dipstick down securely) to check oil level Wipe dipstick

STEP 2" ADD GASOLINE TO THE FUEL TANK
Fill the fuel tank with fresh, clean, unleaded regular
automotive gasoline. (Leaded regular and un}eaded
premium grades of gasoline are acceptable substitutes.)
Q Do not mix oil with gasoline.
Q Do not use gasoline left over from last season or
stored for long periods,,
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 dufing 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 storage for 30 days or longer. Drain 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 instructions for additional information.
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage may occur.
