Checking Oil Level on Engines with Threaded Oil Fill Caps
NOTE: Be sure to check the oil while on a level surface with the
engine stopped.
To avoid engine damage, it is important to:
• Check oil level before each use and every 5 operating
hours when engine is warm. Check oil level more
frequently during engine break-in.
• Keep oil level between "H" and "L" marks on dipstick.
See Fig. 3-3.
• Be sure to rest oil fill cap on the threads when
checking. Do not tighten down oil fill cap when
checking the oil on threaded oil fill cap engines.
1. Remove the oil filler cap/dipstick and wipe the dipstick
clean. See Fig. 3-3.
2. Insert the cap/dipstick into the oil filler neck, but do not
screw it in.
3. Remove the oil filler cap/dipstick. If the level is low, slowly
add oil until oil level registers between high (H) and low (L),
Fig. 3-3.
4. Replace and tighten cap/dipstick firmly before starting
engine.
NOTE: Do not overfill. Overfilling with oil may cause smoking,
hard starting, or spark plug fouling.
NOTE: DO NOT allow oil level to fall below the "L" mark on the
dipstick. Doing so may result in equipment malfunctions or
damage.
NOTE: To change the oil on your engine, see the Maintenance
Section of this manual.

Filling Oil Sump
1. Be sure the engine is upright and level.
2. Remove the oil fill cap dipstick from oil filler tube by
rotating counter-clockwise and lifting the dipstick out of
the engine. Wipe the dipstick clean with a shop rag.
3. Insert oil fill cap dipstick back into oil filler tube. On
quarter-turn oil fill caps, tighten by rotating the cap
clockwise until firmly seated.
NOTE: Some units may have a threaded dipstick. In this
instance, insert the cap/dipstick into the oil filler neck, but
do not screw it in to check.
4. Loosen and remove the oil fill cap dipstick from the oil
filler tube. Note the oil level, if oil reading on the dipstick is
below the "L" mark, slowly add oil to reach the "FULL" level.
See Fig. 3-2 or 3-3, whichever is applicable.
5. Insert oil fill cap dipstick back into oil filler tube. Tighten by
rotating the cap clockwise until firmly seated.
6. Wipe away any spilled oil.
NOTE: To change the oil, see Checking and Changing Oil
instructions in the Maintenance Section of this manual.
