Return choke to o position a er engine starts.
On a cold engine, it may be necessary to leave
choke partially on until engine begins to warm
up.
NOTE: Do not crank the engine continuously
for more than 10 seconds at a time.
If the engine does not start, allow a
60 second cool down period between
starting a empts. Failure to follow
these guidelines can burn out the starter
motor.
NOTE: If the engine develops su cient speed to
disengage the starter but does not keep
running (a false start), engine rotation
must be allowed to come to a complete
stop before a empting to restart the
engine. If the starter is engaged while
the ywheel is rotating, the starter
pinion and ywheel ring gear may clash,
resulting in damage to the starter.
If the starter does not turn the engine over, shut o
starter immediately. Do not make further a empts to
start the engine until the condition is corrected. Do not
jump start using another ba ery (refer to Ba ery). See
your Kohler Engine Service Dealer for trouble analysis.
NOTE: Upon start-up, a metallic ticking may occur.
This is caused by hydraulic li er leakdown
during storage. Run the engine for 5 minutes.
The noise will normally cease in the rst
minute. If noise continues, run the engine at
mid-thro le for 20 minutes. If noise persists,
take the engine to your local Kohler Service
outlet.
