3.2 CHANGING THE ENGINE OIL
AND/OR OIL FILTER
• Change the engine oil after the first 25 hours of
operation (after the 25-hour break-in period, see
Section 2.8.5, Page 10). Thereafter, change the
oil every 100 operating hours. Change the oil more
frequently
if operating consistently under heavy
load or at high ambient temperatures.
• Change the engine oil filter after the first 25 hours
of operation, and every 100 operating hours there­
after.
To change the oil and/or oil filter, proceed as
follows:
1. Run the engine until it is thoroughly warmed up
(at least five minutes) then shut OFF
the engine.
2. With (he engine still warm from running, remove
the oil drain plug (Figure 3.1). Drain the oil into
a suitable conlainer.
3. After the oil lias drained, replace the oil drain
plug. (II only changing the oil, go to step 7.)
4. With the oil drained, remove the old oil filter by
¡uming it counterclockwise (Figure 3.2 on page 12).
5. Apply a light coating of clean engine oil to the gas­
ket of the new filter.
6. Screw the new filter on by hand until its gasket
lightly c'onlacts the oil filter adapter. Then, tight­
en the filter an additional 3/4 to one turn.
7. Remove the dipstick and fill crankcase with the
jn oper type and amount of recommended oil (see
Seedion 1.6.2. Page 6). Tlie engine crankcase can
hold aboul 1.4 liters. DO NOT FILL ABOVE THE
d^TJLi: MARK.
c8. Install and lighten the dipstick before operating
tlu' engiiK'.
9. Start the engine and check for leaks.
NOTE:
Check the oil level and fill to the “FULE’ mark after
checking for leaks. The filter will retain some oil.
