CHECKING AND FILLING ENGINE OIL
As shown in Figs. 7 to 8
CAUTION! The following procedures and adjustments must be performed before the engine
is started.
Do not attempt to make any of these adjustments while the engine is running.
CAUTION! To prevent engine damage, the engine is shipped without oil or gas.
The engine must be filled with the correct grade of oil and gas before starting the engine.
NOTE! Running the engine with a low oil level will cause engine damage. It is recommend that
high-detergent, premium-quality 4-stroke engine oil used. Using non-detergent oil can shorten the
engine's service life, and using 2-stroke oil will damage the engine.
CAUTION! Always use high-quality detergent oil classified SAE30 oil (or equivalent, such as
SAE 5W-30, often called 4-stroke lawn mower oil).
Never use additives with recommended oil.
NOTE: To check the engine oil level, stop engine and place the mower on a level surface.
1. Remove the oil filler dipstick and wipe oil from it with a clean cloth. Insert the dipstick into the oil filler
neck, and tighten it. (see Fig. 7).
2. Remove the dipstick and check the oil level: the oil level must be between the Min and Max marks on the
dipstick. If near the lower level, fill to upper lever with the recommended oil (SAE30 or equivalent). Do not
overfill. Wipe away any spilled oil align the ribs of the cap with the groove of the filler neck, then rotate
to secure it (see Fig. 8).
3. Before using for the first time, add maximum of 15 ounces of oil (supplied, SAE 30)
