SECTION 7: OPERATION
Gas And Oil Fill-Up
Oil:
• Only use high quality detergent oil rated with API service classification SF, SG or SH. Use SAE30 oil; do not
use 10W40 oil.
• Fill oil sump and check the oil level following steps below.
a. Position the mower on level ground and clean area around oil fill plug.
b. Remove oil fill plug and dipstick. Wipe dipstick clean, insert it into oil fill hole and tighten securely.
c. Remove dipstick and check oil level. If the oil is not upto FULL mark on the dipstick, pour recommended oil
through the oil fill and check the level again.
• Install oil fill plug and dipstick, tighten securely.
NOTE: Although multi-viscosity oils (5W30, 10W30, etc.) improve starting in cold weather, these multiviscosity oils
will result in increased oil consumption when used above 32 o F. Check the oil level more frequently to avoid
possible engine damage from running low on oil.
Gasoline
W ARNING: Never fill fuel tank indoors, or when engine is running or hot. Do not smoke when
filling up the fuel tank.
• Clean area around fuel cap. Remove cap. Use a funnel to prevent spillage.
• Pour approximately 1.5 quarts of fresh, regular grade, unleaded gasoline slowly to the fuel tank.
IMPORTANT: Never mix engine oil with gasoline.
• Fill tank to 1/2” below the bottom of the filler neck. Wipe any fuel spillage. Do not fill fuel tank completely.
Provide space for fuel expansion.
Starting Engine
WARNING : Be sure no one other than the operator is standing near the lawn mower while starting
engine or operating mower.
Never run engine indoors or in enclosed, poorly ventilated areas. Engine exhaust contains carbon
monoxide, an odorless and deadly gas. Keep hands, feet, hair and loose clothing away from any
moving parts on engine and lawn mower.
