• Check that any clutches or transmissions are
disengaged or placed in neutral. This is especially
important on equipment with hydrostatic drive. The
shift 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 3 on page 5.
2. Disengage all possible external loads.
3. Be sure the battery is in good condition. A warm
battery has much more starting capacity than a
cold battery.
4. Use fresh winter grade fuel. NOTE: Winter grade
gasoline has higher volatility to improve starting.
Do not use gasoline left over from summer.
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.
Figure 6. Optional Engine Mounted Throttle and
Choke Controls (Carbureted Engines).
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
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 page 8). 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.
