CHECKING ENGINE OIL LEVEL
1. Maintain the engine oil level between “ADD”
mark and “FULL” mark on Oil Level Gauge.
Do not fill crankcase above “FULL” mark.
2. Remove the Oil Filler Cap to add oil, if
necessary. Clean the Oil Filler Cap and replace.
3. The Kubota E-300 is equipped with an Oil
Filter Screen which is attached to the Oil Drain
Plug. Remove the Drain Plug and slide the Filter
Screen completely out. Clean the Filter Screen
with a suitable solvent and air dry. Lubricate the
“O-Ring” and replace unit, tighten securely.
NOTE: Inspect “O-Ring” for damaged, replace
if necessary.

RECOMMENDATIONS
The minimum ambient temperature during cold
engine start-up and the maximum ambient
temperature during engine operation determine the
proper SAE viscosity grade of oil.
Refer to the Engine Oil Viscosity Table below
(Minimum Temperature) in order to determine the
required oil viscosity for starting an engine in cold
conditions.
Refer to the Engine Oil Viscosity Table below
(Maximum Temperature) in order to select the oil
viscosity for engine operation at the highest ambient
temperature that is anticipated.
