Starting
1. Place the throttle control
in
the
idle
position. Place
the choke control into the
“on”
position. See
Figure 5. On dual-fueled engines, place the three-
position fuel control switch in the
gasoline
position
and place the throttle control between half and full
throttle (engine
must
be started and run on
gasoline for 1 minute to heat up oxygen sensor).
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
trouble analysis.
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 Kohler Service
outlet.
Stopping
LPG-Only Engines
1. Turn fuel valve on LPG tank to full closed position
and allow the engine to continue running until it
runs out of fuel. Turn ignition switch to
‘‘off’’
position.
Dual-Fuel Engines
1. Dual-fuel engines may be stopped any of three
ways:
a.
When operating on LPG, one method is the
same as described above for LPG-only
engines.
b.
LPG operation can also be stopped by
moving the three-position fuel control switch
to the
‘‘off ’’
position and letting the engine
run out of fuel. Turn off ignition switch. If
engine will not be restarted for some time,
also close fuel valve at LPG tank.
c.
To stop the engine from gasoline operation, it
should be running between half and full
throttle. Move the three-position fuel control
switch and/or the ignition switch to the
‘‘off ’’
position.
In an
emergency
, move the throttle control to
stop
or turn the ignition switch off.
NOTE: Backfiring may occur when using the
emergency stop method!
Figure 5. Optional Engine Mounted Throttle and
Choke Controls.
2. Slowly turn the fuel valve on the LPG (propane)
tank to full open position. For ‘‘gasoline only’’
operation on dual-fuel units, leave valve closed.
3. Start the engine by activating the key switch.
Release the switch as soon as the engine starts.
Return choke to
‘‘off’’
position after engine starts.
On a cold engine, it may be necessary to leave
choke partially on until engine begins to warm up.
Dual-fuel engines must be allowed to warm up on
gasoline for at least 1 minute. To switch to LPG
operation, move the three-position switch to the
LPG position.
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 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 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.
