colorless, and can cause death if
inhaled. Avoid inhaling exhaust
fumes, and never run the engine in
a closed building or confined area.
California
Proposition 65 Warning
Engine exhaust from this product
contains chemicals known to the
State of California to cause
cancer, birth defects, or other
reproductive harm.
WARNING
Explosive Gas can cause fires and
severe acid burns.
Charge battery only in a well
ventilated area. Keep sources of
ignition away.
Explosive Gas!
Batteries produce explosive
hydrogen gas while being charged.
To prevent a fire or explosion,
charge batteries only in well
ventilated areas. Keep sparks, open
flames, and other sources of
ignition away from the battery at all
times. Keep batteries out of the
reach of children. Remove all
jewelry when servicing batteries.
Before disconnecting the negative
() ground cable, make sure all
switches are OFF. If ON, a spark
will occur at the ground cable
terminal which could cause an
explosion if hydrogen gas or
gasoline vapors are present.

Oil Recommendations
Using the proper type and weight of oil in the
crankcase is extremely important. So is checking oil
daily and changing oil regularly. Failure to use the
correct oil, or using dirty oil, causes premature engine
wear and failure.
Before each start, make sure the crankcase is filled
with proper type and quantity of oil.
Oil Type
Use high quality detergent oil of API (American
Petroleum Institute) service class SG or SH. Select
the viscosity based on the air temperature at the time
of operation as shown in the following table.
Figure 2. Viscosity Grades Table.
Straight 30-weight (Kohler "Magnum") oil is
preferred. SAE 10W-30 oil is not recommended
above 32°F. Using this oil substantially increases oil
consumption and combustion chamber deposits.
NOTE: Using other than service class SG or SH oil or
extending oil change intervals longer than
recommended can cause engine damage.
A logo or symbol on oil containers identifies the API
service class and SAE viscosity grade. See Figure 3.
Figure 3. Oil Container Logo.
Refer to Maintenance Instructions beginning on
page 7 for detailed oil check, oil change, and oil
filter change procedures.

Fuel Recommendations
WARNING: Explosive Fuel!
Gasoline is extremely flammable and its vapors can
explode if ignited. Store gasoline only in approved
containers, in well ventilated, unoccupied buildings,
away from sparks or flames. Do not fill the fuel tank
while the engine is hot or running, since spilled fuel
could ignite if it comes in contact with hot parts or
sparks from ignition. Do not start the engine near
spilled fuel. Never use gasoline as a cleaning agent.
Gasoline/Alcohol blends
Gasohol (up to 10% ethyl alcohol, 90% unleaded
gasoline by volume) is approved as a fuel for Kohler
engines. Other gasoline/alcohol blends are not
approved.
Gasoline/Ether blends
Methyl Tertiary Butyl Ether (MTBE) and unleaded
gasoline blends (up to a maximum of 15% MTBE by
volume) are approved as a fuel for Kohler engines.
Other gasoline/ether blends are not approved.
General Recommendations
Purchase gasoline in small quantities and store in
clean, approved containers. A container with a capacity
of 2 gallons or less with a pouring spout is
recommended. Such a container is easier to handle
and helps eliminate spillage during refueling.
Do not use gasoline left over from the previous
season, to minimize gum deposits in your fuel system
and to insure easy starting.
Do not add oil to the gasoline.
Do not overfill the fuel tank. Leave room for the fuel to
expand.
Fuel Type
For best results use only clean, fresh, unleaded
gasoline with a pump sticker octane rating of 87 or
higher. In countries using the Research method, it
should be 90 octane minimum.
Unleaded gasoline is recommended as it leaves less
combustion chamber deposits. Leaded gasoline may
be used in areas where unleaded is not available and
exhaust emissions are not regulated. Be aware
however, that the cylinder head will require more
frequent service.
Engine Identification Numbers
When ordering parts, or in any communication
involving an engine, always give the Model,Specification, and Serial Numbers of the engine.
The engine identification numbers appear on decal (or
decals) affixed to the engine shrouding. Include letter
suffixes, if there are any.
Record your engine identification numbers on the

Operating Instructions
Also read the operating instructions of the equipment this engine powers.
Pre-Start Checklist
o Check oil level. Add oil if low. Do not overfill.
o Check fuel level. Add fuel if low.
o Check cooling air intake areas and external
surfaces of engine. Make sure they are clean and
unobstructed.
o Check that the air cleaner components and all
shrouds, equipment covers, and guards are in
place and securely fastened.
o 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.
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), the engine
rotation must be allowed to come to a
complete stop before attempting to
restart the engine. If the start 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 below). See your Kohler Engine
Service Dealer for trouble analysis.
Stopping
Turn ignition switch OFF.
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. A warm battery has much more starting capacity
that a cold battery.
4. Use fresh winter grade fuel. NOTE: Winter grade
gasoline has a higher volatility to improve
starting. Do not use gasoline left over from
summer.
Starting
1. Move the throttle control lever to IDLE (slow)
position. For engines without automatic choke,
move choke lever into full choke position and
gradually return to OFF position after engine
starts and warms up.
2. Start the engine as follows:
For an Electric Start Engine Activate the
starter switch. Release the switch as soon as the
engine starts.
Figure 5.
Instrument panel is standard on basic engine. Choke,
throttle, oil pressure gauge, ammeter, start button, and
stop switch are all positioned for easy operation.
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 10).
