NOTE: Do not crank engine continuously for more than 10 seconds. Allow a 60 second cool down period between
starting attempts. Failure to follow these guidelines can burn out starter motor.
NOTE: If engine develops suf
fi
cient speed to disengage starter but does not keep running (a false start), engine
rotation must be allowed to come to a complete stop before attempting to restart engine. If starter is engaged
while
fl
ywheel is rotating, starter pinion and
fl
ywheel ring gear may clash and damage starter.
NOTE: If starter does not crank engine, shut off starter immediately. Do not make further attempts to start engine until
condition is corrected.
NOTE: Do not drop starter or strike starter frame. Doing so can damage starter.
Engines in this series use solenoid shift starters.

hydrostatic drive. Transmission must be exactly in neutral to
prevent resistance which could keep engine from starting.
Check for seized engine components such as bearings,
connecting rod, and piston.
