To Check Engine Oil Level
Refer to your specific model in Figure 7-1.
The engine oil level must be in the safe
range between (“F” Full) and (“L” Add)

before each use. To check oil level:
1. Remove dipstick (A, Fig. 7-1).

2. Wipe oil from dipstick with a clean
cloth. Insert dipstick back into place.
3. Remove dipstick and check oil level.
The oil level is indicated by marks on
the dipstick. Keep level between the
(“F” Full) and (“L” Add) marks. If
level is low, fill engine crankcase
through fill opening (B, Fig. 7-1).
New Engine: Change the engine oil after
the first 5 hours of use, then change oil
every 25 operating hours.

ALWAYS DISPOSE OF OIL IN AN
ECOLOGICALLY FRIENDLY MANNER.
Changing Engine Oil
Change oil after the first 5 operating hours
of operation and every 25 operating hours
thereafter. Drain oil while it is hot. Hot oil
flows more freely and carries away more
impurities. To change oil:

remove left side panel by unscrewing
and removing knobs (J, Fig. 7-3).
2. Remove yellow cap from oil drain
tube (L, Fig. 7-4). Attach oil drain
hose to oil drain tube.
3. Direct hose end into a container.
Turn oil drain valve and drain oil.
4. Turn and close oil drain valve. Re-
connect yellow cap to oil drain tube.
5. Fill engine crankcase with oil at fill
opening (B, Fig. 7-1). See engine
manual for the correct oil type. Fill to
level indicated on dipstick, between
the (“F” Full) and (“L” Add) marks.
NEVER OVERFILL ENGINE CRANKCASE.

operating hours. Refer to the engine
manual for filter specifications and part
number. To change oil filter:

(M, Fig. 7-4). Wipe off filter adapter
(area behind filter).
