3.6 Engine Oil
It is important that the proper type of oil be used in the crankcase. It is also important that
the oil level and quality be checked daily. Use of incorrect oil, inadequate oil level, or con-
taminated oil will cause engine damage.
Be sure the Articulator is parked on level ground before checking the oil level. Always
check the oil level before starting the engine, or more than five minutes after turning the
engine off. Check the oil level with the dipstick located under the engine cover, on top of
the engine, to the right of the oil intake cap. To add or change the engine oil and/or oil fil-
ter, allow ample time for the engine and engine oil to cool. Consult the Kubota Diesel
Engine Operator’s Manual located at the back of this manual for the proper procedures.
When operating in temperatures ranging from 32° - 77°F (0° - 25°C), engine oil should be
MIL-L-2104C or have properties of API classification CD/CE grades, with an SAE viscos-
ity grade of 10W-30. Due to the nature of the lawn care industry, it is assumed that oper-
ation of the Articulator will typically be in air temperatures within the above listed range. In
the unlikely event that you will be operating the Articulator in air temperatures outside of
this range, consult the Kubota Diesel Engine Operator’s Manual located in the back of
this manual for the proper SAE viscosity grade of oil that should be used.
3.7 Air Cleaner
The air cleaner is located under the engine cover, to the upper front of the engine. There
are two filter elements within the air cleaner. The cap (located on the rear of the air
cleaner) is opened by simultaneously pushing it inward and turning it counter-clockwise.
Check that both filter elements are clean and free of debris. Clean or replace if neces-
sary. Consult the Kubota Diesel Engine Operator’s Manual located at the back of this
manual for the proper procedures.
Be sure to use the correct oil in the engine crankcase!
Be sure to check the engine oil level and quality daily!
Incorrect oil, inadequate oil level, or contaminated oil will cause
engine damage!
ALWAYS turn off engine before checking the oil level, changing the
oil, or changing the oil filter!
ENGINE OIL IS HOT! ALWAYS allow ample time for oil to cool before
changing or repairing leaks!
