Engine Oil
The normal oil change interval is every
500 service hours or one year, which
ever comes first. Engines which are
operated under harsh conditions should
have the oil changed every 250 service
hours or every 6 months, which ever
comes first. Harsh conditions include:
operation in high temperatures, continu-
ous high load applications, and abnor-
mally dusty/dirty conditions.
To change engine oil:
1. Run engine for a few minutes to
warm the engine oil.
2. Remove the drain plug (item 1, photo
A) from the oil pan.
3. Drain oil into suitable container.
4. Remove engine oil filter, make sure
gasket is also removed.
5. Apply fresh oil to the new filter gasket
surface and install new filter.
6. Tighten filter to specifications on filter
label or box.
7. Refill engine to capacity with oil as
specified.
