Safety Precautions (Cont.)
WARNING
Accidental Starts can cause severe
injury or death.
Disconnect and ground spark plug
lead before servicing.
Accidental Starts!
Disabling engine. Accidental starting
can cause severe injury or death.
Before working on the engine or
equipment, disable the engine as
follows: 1) Disconnect the spark
plug lead(s). 2) Disconnect negative
(-) battery cable from battery.
WARNING
Carbon Monoxide can cause
severe nausea, fainting or death.
Do not operate engine in closed or
confined area.
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.
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 the proper type and quantity of oil.
Oil Type
Use high quality detergent oil of API (American
Petroleum Institute) service class SG, SH, SJ or
higher. Select the viscosity based on the air
temperature at the time of operation as shown in the
following table.
Refer to Maintenance Instructions beginning on
page 7 for detailed oil check and oil 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.
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.
*Use of synthetic oil having 5W-20 or 5W-30 rating is
acceptable, up to 40°F.
**Synthetic oils provide better starting in extreme cold
(below -10°F).
Figure 2. Viscosity Grades Table.
Straight 30-weight 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, SH, SJ or
higher oil or extending oil change intervals
longer than recommended can cause engine
damage which is not covered by the engine
warranty.
A logo or symbol on oil containers identifies the API
service class and SAE viscosity grade. See Figure 3.
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.
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.
Figure 3. Oil Container Logo.
4
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.
Engine Identification Numbers
When ordering parts, or in any communication involving
an engine, always give the Model, Specification, andSerial Numbers of the engine.
The engine identification numbers appear on a decal
affixed to the engine shrouding. Include letter suffixes, if
there are any.

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
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 2 on page 4.
2. Declutch all possible external loads.
