MAINTENANCE AND REPAIR INSTRUCTIONS

CHANGING THE OIL
For a new engine, change the oil after the first
10 hours
of operation. Thereafter, change the
oil after every
25 hours
or before storing the
unit for an extended period of time.
It is best to change the oil while the engine is
still warm. The oil will flow freely and carry away
more impurities.
CAUTION:
Wear gloves to prevent
injury when handling the unit.
Change the oil as follows:
1. Remove the oil fill plug / dipstick.
2. Pour the oil into a container by tipping the
unit to a vertical position (Fig. 43). Be sure
to allow ample time for complete drainage.
3. Wipe up any oil residue on the unit and clean
up any oil that may have spilled. Dispose of
the oil according to Federal, State and local
regulations.
4. Refill the crankcase with 3.4 fluid oz (100 ml)
of SAE 30 SF, SG, SH oil. Use the bottle and
spout from initial use.
5. Reinstall the oil fill plug /dipstick.
NOTE:
Make sure the O-ring is in place on the
oil fill plug / dipstick when checking
and changing the oil (Fig. 42, Pg. 21).

CHECKING / ADJUSTING VALVE TO
ROCKER ARM CLEARANCE
Every
50 hours
of operation, inspect the
valve to rocker arm clearance using a flat
feeler gauge.
NOTE:
This requires some disassembly of
the engine. If you feel unsure or
unqualified to perform this, take the
unit to an authorized service center.
NOTE:
The engine must be cold when
checking or adjusting the valve
clearance.
This task should be performed inside, in a
clean, dust free area.
1. Loosen the two (2) screws shown in figure 44.
2. Remove the three (3) screws that secure the
engine cover (Figs. 44 and 45).
