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.
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 8 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.
General Recommendations
**
*
*Use of synthetic oil having 5W-20 or 5W-30 rating is acceptable,
up to 4°C (40°F).
**Synthetic oils will provide better starting in extreme cold below
23°C (-10°F).
Figure 3. Viscosity Grades Table.
NOTE: Using other than service class SG, SH, SJ or
higher oil or extending oil change intervals
longer than recommended can cause engine
damage.
NOTE: Synthetic oils meeting the listed classifications
may be used with oil changes performed at the
recommended intervals. However to allow
piston rings to properly seat, a new or rebuilt
engine should be operated for at least 50
hours using standard petroleum based oil
before switching to synthetic oil.
A logo or symbol on oil containers identifies the API
service class and SAE viscosity grade. See Figure 4.
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
ensure 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 the 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 and reduces harmful
exhaust emissions. Leaded gasoline is not
recommended and must not be used on EFI engines,
or on other models where exhaust emissions are
regulated.
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 4. Oil Container Logo.
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 engine. Other
gasoline/ether blends are not approved.

Pre-Start Checklist
1. Be sure to use the proper oil for the temperature
expected. See Figure 3 on page 5.
2. Declutch 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.
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 the starter motor.
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.
Stopping
1. Remove the load by disengaging all PTO driven
attachments.
2. For Carbureted Engines Without A Shutdown
Solenoid: Move the throttle to the ‘‘slow’’ or
‘‘low’’ idle position. Allow the engine to run at idle
for 30-60 seconds; then stop the engine.
For Carbureted Engines Equipped With A
Shutdown Solenoid: Position the throttle control
between half and full throttle; then stop the engine.
For EFI Engines: Move the throttle to the "slow"
or "idle" position; turn key "off" to stop engine.
Battery
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.
A 12 volt battery is normally used. Refer to the
operating instructions of the equipment this engine
powers for specific battery requirements.
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.
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” mark on the dipstick.
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”). See your Kohler Engine
Service Dealer for service assistance.
NOTE: Do not operate this engine continuously at
angles exceeding 25° in any direction. Engine
damage could result from insufficient
lubrication.
If the battery charge is not sufficient to crank the
engine, recharge the battery (see page 14).
Operating
Refer to the operating instructions of the equipment
this engine powers. Because of equipment design or
application, there may be more stringent restrictions
regarding the angle of operation.
7
Cooling
NOTE: If debris builds up on the grass screen or
other cooling areas, stop the engine
immediately and clean. Operating the engine
with blocked or dirty air intake and cooling
areas can cause extensive damage due to
overheating. See Clean Air Intake/Cooling
Area, page 13.
Engine Speed
NOTE: Do not tamper with the governor setting to
increase the maximum engine speed.
Overspeed is hazardous and will void the
engine warranty. The maximum allowable
high idle speed for these engines is 3750
RPM, no load.
WARNING: Hot Parts!
Engine components can get extremely hot from
operation. To prevent severe burns, do not touch these
areas while the engine is running, or immediately after
it is turned off. Never operate the engine with heat
shields or guards removed.
Maintenance Instructions
Maintenance, repair, or replacement of the emission control devices and systems, which are being done at
the customers expense, may be performed by any non-road engine repair establishment or individual.
Warranty repairs must be performed by an authorized Kohler service outlet.
WARNING: 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.

Check Oil Level
The importance of checking and maintaining the proper
oil level in the crankcase cannot be overemphasized.
Check oil BEFORE EACH USE as follows:
1. Make sure the engine is stopped, level, and is
cool so the oil has had time to drain into the sump.
2. To keep dirt, debris, etc., out of the engine, clean
the area around the dipstick before removing it.
3. Unthread and remove the dipstick; wipe oil off.
Reinsert the dipstick into the tube and rest the cap
on the tube. Do not thread the cap onto the tube.
See Figure 6.
NOTE: To prevent extensive engine wear or
damage, always maintain the proper oil
level in the crankcase. Never operate the
engine with the oil level below the “ADD”
mark or over the “FULL” mark on the
dipstick.
Oil Sentry™
Some engines are equipped with an optional Oil
Sentry™ oil pressure switch. If the oil pressure drops
below an acceptable level, the Oil Sentry™ will either
shut off the engine or activate a warning signal,
depending on the application.
NOTE: Make sure the oil level is checked BEFORE
EACH USE and is maintained up to the
“FULL” mark on the dipstick. This includes
engines equipped with Oil Sentry™.
Change Oil and Filter, Service Oil Cooler
Change Oil
Change oil after every 100 hours of operation (more
frequently under severe conditions). Refill with service
class SG, SH, SJ or higher oil as specified in the
‘‘Viscosity Grades’’ table (Figure 3) on page 5.
Figure 6. Checking Oil Level.
4. Pull the dipstick out and check the oil level.

(gold) allow inspection and cleanout of the cooling fins,
without removing the blower housing.
NOTE: Operating the engine with a blocked grass
screen, dirty or plugged cooling fins, and/or
cooling shrouds removed, will cause engine
damage due to overheating.
Ignition System
Carbureted Engines - Use an electronic Capacitive
Discharge (CD) ignition system. Other than periodically
checking/replacing the spark plugs, no maintenance,
timing, or adjustments are necessary or possible with
this system.
EFI Engines - Incorporate a computer-controlled
battery ignition system with individual coils. Other than
periodically checking/replacing the spark plugs, no
maintenance, timing, or adjustments are necessary or
possible with this system.

Check Spark Plugs
Battery Charging
Every 200 hours of operation, remove the spark plugs,
check condition, and reset the gap or replace with new
plugs as necessary. The standard spark plug is a
Champion® RC12YC (Kohler Part No. 12 132 02-S). A
high-performance spark plug, Champion® Platinum
3071 (used on Pro Series engines, Kohler Part No.
25 132 12-S) is also available. Equivalent alternate
brand plugs can also be used.
1. Before removing the spark plug, clean the area
around the base of the plug to keep dirt and debris
out of the engine.
2. Remove the plug and check its condition. Replace
the plug if worn or reuse is questionable.
NOTE: Do not clean the spark plug in a machine
using abrasive grit. Some grit could
remain in the spark plug and enter the
engine causing extensive wear and
damage.
3. Check the gap using a wire feeler gauge. Adjust
the gap to 0.76 mm (0.030 in.) by carefully
bending the ground electrode. See Figure 16.
4. Reinstall the spark plug into the cylinder head.
Torque the spark plug to 24.4-29.8 N·m
(18-22 ft. lb.).
Wire Gauge
WARNING: 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.
Fuel System
WARNING: Fuel System Under Pressure!
The EFI fuel system operates under high pressure, and
the fuel filter and fuel line used must be approved
system components only. Use of substitute parts can
result in system failure, gasoline leakage and possible
explosion.
Fuel Filter
Carbureted Engines: Most engines are equipped with
an in-line fuel filter. Periodically inspect the filter and
replace with a genuine Kohler filter every 200
operating hours.
EFI Engines: A special, high volume, high pressure
filter with greater filtration capabilities and internal
surface area is used. See Figure 17.

Replacement is recommended every 1500 hours, or
more frequently under extremely dusty or dirty
conditions. When replacement is necessary, always
use genuine Kohler parts.
Fuel Line
EFI Engines: A special fuel line, capable of
withstanding the high pressure of the EFI fuel system,
is used (must meet SAE R9 specifications). See Figure
17. If fuel line must be replaced, see your Kohler
Engine Service Dealer.
Carburetor Troubleshooting and
Adjustments
NOTE: Carburetor adjustments should be made
only after the engine has warmed up.
The carburetor is designed to deliver the correct
fuel-to-air mixture to the engine under all operating
conditions. The high idle mixture is set at the factory
and cannot be adjusted. The low idle fuel adjusting
needle (if equipped) is also set at the factory and
normally does not need adjustment.
NOTE: To ensure correct engine operation at
altitudes above 1525 meters (5000 ft.), it may
be necessary to have an authorized Kohler
dealer install a special high-altitude jet kit in
the carburetor. If a high-altitude kit has been
installed, the engine must be reconverted to
the original jet size, before it is operated at
lower altitudes, or overheating and engine
damage can result.

• Make sure the fuel tank cap vent is not blocked
and that it is operating properly.
• If the fuel tank is equipped with a shut-off valve,
make sure it is open.
• If the engine is equipped with an in-line fuel filter,
make sure it is clean and unobstructed. Replace
the filter if necessary.
• Make sure fuel is reaching the carburetor. This
includes checking the fuel lines and fuel pump for
restrictions or faulty components, replace as
necessary.
• Make sure the air cleaner element is clean and all
air cleaner element components are fastened
securely.
If, after checking the items listed above, the engine is
hard to start, runs roughly, or stalls at low idle speed, it
may be necessary to adjust or service the carburetor.
Adjust Carburetor
NOTE: Certified engines may have a fixed idle fuel
adjusting needle. Do not attempt steps 1 and
2 below. Proceed directly to step 3.
1. With the engine stopped, turn the low idle fuel
adjusting needle in (clockwise) until it bottoms
lightly.
NOTE: The tip of the low idle fuel adjusting
needle is tapered to critical dimensions.
Damage to the needle and the seat in
carburetor body will result if the needle is
forced.
2. Preliminary Settings: Turn the adjusting needle
out (counterclockwise) from lightly bottomed
2-1/4 turns.

Troubleshooting
3. Start the engine and run at half throttle for 5 to 10
minutes to warm up. The engine must be warm
before making final settings (steps 4, 5, and 6).
4. Low Idle Speed Setting: Place the throttle control
into the “idle” or “slow” position. Set the low idle
speed to 1200 RPM* (± 75 RPM) by turning the
low idle speed adjusting screw in or out. Check
the speed using a tachometer.
If engine troubles are experienced that appear to be
fuel system related, check the following areas before
adjusting the carburetor.
15
*NOTE: The actual low idle speed depends on the
application – refer to equipment
manufacturer’s recommendations. The
recommended low idle speed for basic
engines is 1200 RPM. To ensure best
results when setting the low idle fuel
needle, the low idle speed must not
exceed 1200 RPM (± 75 RPM).
5. Low Idle Fuel Needle Setting: Place the throttle
into the “idle” or “slow” position. Turn the low
idle fuel adjusting needle in (slowly) until engine
speed decreases and then back out approximately
3/4 to 1 turn to obtain the best low speed
performance.
• Make sure the proper fuel filter is being
used, and it is clean and unobstructed. Replace
filter only with genuine Kohler parts.
• Make sure all connections to sensors, ECU,
and fuel injectors are properly secured.
• Make sure a good 12 volt battery is being used
and is fully charged.
If these checks do not correct the problem, or the MIL
remains on, further diagnosis and servicing by an
authorized Kohler Engine Dealer is necessary.
Adjustment – EFI Throttle Body
6. Recheck the idle speed using a tachometer.
Readjust the speed as necessary.
Electronic Fuel Injection (EFI) System
The EFI system is a complete, electronically-controlled,
fuel management system, designed to deliver a
precisely controlled fuel flow under all operating
conditions. The electronic control unit (ECU), the
"brain" of the system, automatically adjusts fuel
delivery and ignition timing based upon load, speed,
operating temperature, and exhaust emission levels.
The low idle speed is the only manual adjustment
possible. The ECU continuously monitors operation of
the EFI system. If it detects a problem or fault within
the system, it will illuminate the malfunction indicator
light (MIL), which is mounted in view of the operator.
This is a signal that normal, programmed operation
has been affected, and service by an authorized Kohler
Engine Dealer is required.
NOTE: Do not spray water at the wiring harness or
any of the electrical components, especially
the ECU, as it could cause malfunction,
damage, or failure.
Troubleshooting
Low Idle Speed (RPM) is the only adjustment that can
be made. All other fuel calibrations are controlled by
the ECU. The standard low idle speed is 1500 RPM*
(± 75 RPM).
*NOTE: The actual low idle speed depends on the
application -- refer to equipment
manufacturer's recommendations.
When an EFI engine is started cold, the ECU will
briefly set a higher (200-400 RPM) low idle speed,
similar to a fast idle. Do not attempt to perform any
readjustment during this "warm-up" period.
If adjustment is to be made, the engine must be at
operating temperature, air cleaner in place, and check
engine light must be off (no fault codes present).
1. Start the engine and run at half throttle for 5 to 10
minutes to warm up.
2. Place the throttle control into the “idle” or “slow”
position.
3. Turn the low idle speed adjusting screw in or out
and check RPM with a tachometer. See Figure 19.
If the MIL comes on, or the engine becomes hard to
start, runs roughly, or stalls at low idle speed, initial
checks should be made in the following areas:
• Make sure the fuel tank is filled with clean,
Fuel Rail
fresh gasoline, and shut-off valve (if so
equipped)is opened completely.
Low Idle Speed
Adjusting Screw
• Make sure fuel tank vent cap is not blocked and
it is operating properly.
• Make sure the air cleaner element and
precleaner are clean and all components are
properly secured. Clean or replace as
necessary.

Troubleshooting
When troubles occur, be sure to check the simple causes which, at first, may seem too obvious to be considered.
For example, a starting problem could be caused by an empty fuel tank. Some common causes of engine troubles
are listed in the following table.
Do not attempt to service or replace major engine components, or any items that require special timing or
adjustment procedures. Have your Kohler Engine Service Dealer do this work.

Storage
Parts Ordering
If the engine will be out of service for two months or
more, use the following storage procedure:
1. Clean the exterior surfaces of the engine. On EFI
engines, avoid spraying water at the wiring
harness or any of the electrical components.
The engine Specification, Model, and Serial Numbers
are required when ordering replacement parts from
your Kohler Engine Service Dealer. These numbers are
found on the identification plate which is affixed to the
engine shrouding. Include letter suffixes if there are
any. See “Engine Identification Numbers” on page 6.
2. Change the oil and filter while the engine is still
warm from operation. See “Change Oil and Oil
Filter” on page 9.
Always insist on genuine Kohler parts. All genuine
Kohler parts meet strict standards for fit, reliability, and
performance.
3. The fuel system must be completely emptied, or
the gasoline must be treated with a stabilizer to
prevent deterioration. If you choose to use a
stabilizer, follow the manufacturers
recommendations, and add the correct amount for
the capacity of the fuel system. Fill the fuel tank
with clean, fresh gasoline. Run the engine for 2-3
minutes to get stabilized fuel into the carburetor.
Close fuel shut off valve when unit is being stored
or transported.
Major Repair
Major repair information is available in Kohler Engine
Service Manuals. However, major repair generally
requires the attention of a trained mechanic and the
use of special tools and equipment. Your Kohler
Engine Service Dealer has the facilities, training, and
genuine Kohler replacement parts necessary to
perform this service. For Sales & Service assistance
call 1-800-544-2444 (U.S. & Canada) or contact your
Kohler Engine Dealer or Service Distributor, they're in
the Yellow Pages under Engines-Gasoline.
To empty the system, run the engine until the tank
and system are empty.
4. Remove the spark plugs. Add one tablespoon of
engine oil into each spark plug hole. Install plugs,
but do not connect the plug leads. Crank the
engine two or three revolutions.
5. On units with EFI engines, disconnect the
negative (-) battery cable or use a "battery minder"
trickle charger while the unit is in storage.
6. Store the engine in a clean, dry place.
