Engine Oil
The mower is shipped
WITHOUT OIL in the engine.
A bottle of oil is included in the
box with your mower. Add the
entire contents of the oil bottle
into the oil filler opening.
All Honda engines are run at the
factory prior to packaging. Most
of the oil is removed prior to
shipment; however, some oil
remains in the engine. The
amount of oil left in the engine
varies.
If not using the supplied oil, add
enough SAE 10W-30 API
service category SJ or later oil to
bring the oil level between the
upper and lower limit marks on
the dipstick as shown.
Do not overfill engine with oil.
If the engine is overfilled, the
excess oil may get transferred to
the air cleaner housing and air
filter.
After filling the engine with oil,
remove the hang tag near the recoil starter grip that says "The engine
has no oil. A container of oil is in the shipping box."
