Starting an Engine Equipped with Smart-Choke

NOTE: Do not crank engine continuously for more than
10 seconds at a time. If engine does not start,
allow a 60 second cool down period between
starting attempts. Failure to follow these
guidelines can burn out starter motor.
NOTE: If engine develops sufficient 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 flywheel is
rotating, starter pinion and flywheel ring gear
may clash, resulting in damage to starter.
1. Smart-Choke system will automatically control
™
choke plate position for starting.
2. Make sure equipment is in neutral.
3. Activate starter switch. Release switch as soon as
engine starts.
If starter does not turn engine over, shut starter off
immediately. Do not make further attempts to start
engine until condition is corrected. Do not jump start
using another battery. See your Kohler authorized
dealer for trouble analysis.
4. For operation, after engine starts, move throttle and
set desired engine operating speed.
