flywheel is rotating, the starter pinion and
flywheel ring gear may clash resulting in
damage to the starter.
If the starter does not turn the engine over, shut off
starter immediately. Do not make further attempts
to start the engine until the condition is corrected.
Do not jump start using another battery (refer to
“Battery” on this page). See your Kohler Engine
Service Dealer for service assistance.
Carbureted Engines Only:
3. For a Cold Engine – Gradually return the choke
control to the “off” position after the engine starts
and warms up.
The engine/equipment may be operated during
the warm-up period, but it may be necessary to
leave the choke partially on until the engine
warms up.
4. For a Warm Engine – Return choke to “off”
position as soon as engine starts.
Stopping
1. Remove the load by disengaging all PTO driven
attachments.
2. For Carbureted Engines Without A Shutdown
Solenoid: Move the throttle to the “slow” or
“low” idle position. Allow the engine to run at idle
for 30-60 seconds; then stop the engine.
For Carbureted Engines Equipped With A
Shutdown Solenoid: Position the throttle control
somewhere between half and full throttle; then
stop the engine.
For EFI Engines: Move the throttle to the "slow"
or "idle" position; turn key ‘‘off’’ to stop engine.
Battery
A 12 volt battery is normally used. Refer to the
operating instructions of the equipment this engine
powers for specific battery requirements.
If the battery charge is not sufficient to crank the
engine, recharge the battery (see page 13).
Operating
Angle of Operation
This engine will operate continuously at angles up to
25°. Check oil level to assure crankcase oil level is at
the “F” mark on the dipstick.
Figure 6. Optional Engine Mounted Throttle and
Choke Controls (CH18-25,CH730,740).
2. Start the engine by activating the key switch.
Release the switch as soon as the engine starts.
EFI Engines Only – Initial Starting or After Running
out of Fuel (Dry System)
a. Turn the key switch to the “on” position for one
minute. Allow the fuel pump to cycle and prime
the system. Turn the key switch “off”.
b. Turn the key switch to the “start” position,
crank and start engine.
c. If the engine fails to start, repeat steps “a” and
“b”. If the engine does not start after two priming
intervals, contact your Kohler Engine Service
Dealer for further assistance.
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
attempts. Failure to follow these
guidelines can burn out, or permanently
damage, the starter motor.
NOTE: Upon start-up, a metallic ticking may
occur. This is caused by hydraulic lifter
leakdown during storage. Run the engine
for 5 minutes. The noise will normally
cease in the first minute. If noise
continues, run the engine at mid-throttle
for 20 minutes. If noise persists, take the
engine to your local authorized Kohler
Engine Service Dealer.
NOTE: If the engine develops sufficient 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 attempting to restart the
engine. If the starter is engaged while the
Starting
1. Place the throttle control midway between the
‘‘slow’’ and ‘‘fast’’ positions. Place the choke
control (non-EFI engines only) into the ‘‘on’’
position. See Figure 6.
