CAUTION:_

In order to prevent clutch slippage (since
the engine oil also lubricates the clutch),
do not mix any chemical additives. Do not
use oils with a diesel specification of “CD”
or oils of a higher quality than specified. In
addition, do not use oils labeled “ENERGY
CONSERVING II” or higher.


Make sure that no foreign material enters
the crankcase.

NOTE:

If the engine fails to start, release the start
switch, then push the start switch again.
Pause a few seconds before the next attempt.
Each cranking should be as short as possible
to preserve battery energy. Do not crank the
engine more than 10 seconds on each at-
tempt.


If the battery is discharged, pull the recoil
starter to start the engine.
7. If the engine is started with the starter (choke)
in position
1, the starter (choke) should be
returned to position
2 to warm up the engine.
If the engine is started with the starter (choke)
in position
2, keep the starter (choke) in this
position to warm up the engine.
8. Continue warming up the engine until it idles
smoothly and return the starter (choke) to po-
sition

See the “Engine break-in” section prior to op-
erating engine for the first time.
