Operating Instructions
Also read the operating instructions of the equipment this
engine powers.
Pre-Start Checklist
• Check oil level. Add oil if low. Do not overfill.
• Check fuel level. Add fuel if low.
• Check cooling air intake areas and external
surfaces of engine. Make sure they are clean and
unobstructed.
• Check that the air cleaner components and all
shrouds, equipment covers, and guards are in
place and securely fastened.
• Check that any clutches or transmissions are
disengaged or placed in neutral. This is especially
important on equipment with hydrostatic drive.
The shi lever must be exactly in neutral to
prevent resistance which could keep the engine
from starting.
WARNING: Lethal Exhaust Gases!
Engine exhaust gases contain poisonous carbon monoxide.
Carbon monoxide is odorless, colorless, and can cause death
if inhaled. Avoid inhaling exhaust fumes, and never run the
engine in a closed building or confined area.
Cold Weather Starting Hints
1. Be sure to use the proper oil for the temperature
expected. See Figure 2 on page 4.
2. Declutch all possible external loads.
3. Be sure the baery is in good condition. A warm
baery has much more starting capacity than a
cold baery.
4. Use fresh winter grade fuel. NOTE: Winter grade
gasoline has higher volatility to improve starting.
Do not use gasoline le over from summer.
Starting
1. Place the throle control midway between the
slow and fast positions. Place the choke control
into the on position.
2. Start the engine by activating the key switch.
Release the switch as soon as the engine starts.
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 aempts. Failure
to follow these guidelines can burn out the
starter motor.
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
aempting to restart the engine.
If the starter is engaged while the 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 aempts to
start the engine until the condition is corrected. Do
not jump start using another baery (refer to Baery).
See your Kohler Engine Service Dealer for service
assistance.
3. For a Cold Engine – Gradually return the choke
control to the off position aer 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
aachments.
2. For Engines without a Shutdown Solenoid:
Move the throle to the slow or low idle position.
Allow the engine to run at idle for 30-60 seconds;
then stop the engine.
For Engines Equipped with a Shutdown
Solenoid: Position the throle control between
half and full throle; then stop the engine.
Battery
A 12 volt baery is normally used. Refer to the
operating instructions of the equipment this engine
powers for specific baery requirements.
If the baery charge is not sufficient to crank the
engine, recharge the baery.
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 FULL or “F” mark on the dipstick.
