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 including E20
and E85 are not to be used and not approved. Any
failures resulting from use of these fuels will not be
warranted.
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.

Operating Instructions
Also read the operating instructions of the equipment this
engine powers.
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 buildingor 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. 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.
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 midthrottle for 20 minutes. If noise persists,
take the engine to your local Kohler
Service outlet.
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). 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.
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
A 12 volt battery is normally used. Refer to the
operating instructions of the equipment this engine
powers for specific battery requirements.
7
If the battery charge is not sufficient to crank the
engine, recharge the battery (see page 14).
Operating
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.
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.
NOTE: Do not operate this engine continuously at
angles exceeding 25° in any direction. Engine
damage could result from insufficient
lubrication.
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.
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.
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.

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.
Change the oil while the engine is still warm. The oil
will flow more freely and carry away more
impurities. Make sure the engine is level when filling,
checking, or changing the oil.
Figure 6. Checking Oil Level.
4. Pull the dipstick out and check the oil level.
The oil level should be up to, but not over, the

To ensure proper cooling, make sure the grass screen,
cooling fins, and other external surfaces of the engine
are kept clean at all times.
Every 100 hours of operation (more often under
extremely dusty, dirty conditions), remove the blower
housing* and other cooling shrouds. Clean the cooling
fins and external surfaces as necessary. Make sure the
cooling shrouds are reinstalled.
Figure 14. Removing Elements.
3. After the main element is removed, check the
condition of the inner element. It should be
replaced whenever it appears dirty, typically
every other time the main element is replaced.
Clean the area around the base of the inner
element before removing it, so dirt does not get
into the engine.
4. Do not wash the paper element and inner
element or use pressurized air, this will damage
the elements. Replace dirty, bent or damaged
elements with new genuine Kohler elements as
required. Handle new elements carefully; do not
use if the sealing surfaces are bent or damaged.
5. Check all parts for wear, cracks, or damage.
Replace any damaged components.
*Cleanout kits 25 755 20-S (black) or 25 755 21-S (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.
13
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). RFI
compliant engines use a Champion® XC12YC (Kohler
Part No. 25 132 14-S) spark plug. 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.
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
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.).
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.

Carburetor Troubleshooting and
Adjustments
Engines in this series use either a single barrel or two
barrel carburetor depending on model, and may also
be equipped with a Governed Idle System. Specific
adjustment procedure(s) are provided based on the
model and carburetor involved. If the engine is
equipped with a Governed Idle System, refer to
Models with Governed Idle System when performing
any carburetor adjustment, as an additional step to
the listed procedure(s) is required.
NOTE: Carburetor adjustments should be made
only after the engine has warmed up.

Troubleshooting
If engine troubles are experienced that appear to be
fuel system related, check the following areas before
adjusting the carburetor.
• Make sure the fuel tank is filled with clean, fresh
gasoline.
• 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.
15
• 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
Models CV18-740
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.
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).
6. Recheck the idle speed using a tachometer.
Readjust the speed as necessary.
Models with Governed Idle System
An optional governed idle control system is supplied
on some CV18-740 engines. The purpose of this
system is to maintain a desired idle speed regardless
of ambient conditions (temperature, parasitic load,
etc.) that may change. Engines with this feature
contain a small secondary spring connected between
the governor lever and the lower adjustment tab of
the main bracket. See Figure 20.
The system requires an additional procedure for
setting the idle speed. If speed adjustments are
required proceed as follows.
1. Make any necessary speed or control
adjustments following the appropriate
instructions covered in this section.
2. Move the throttle control to the idle position.
Hold the governor lever away from the
carburetor, or hold the throttle lever so it is tight
against the idle speed adjusting screw, to negate
the governor activation. See Figure 21. Check the
speed with a tachometer and adjust it to 1500
RPM.
3. Release the governor lever and allow the engine
to return to the governed idle speed. Check it
with a tachometer against the equipment
manufacturers recommended idle speed.
Governed Idle Speed (RPM) is typically 300 RPM
(approximate) higher than the low idle speed. If
adjustment is necessary, bend the adjusting tab
on the speed control assembly to set. See Figure
20.
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.
*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).

Electronic Fuel Injection (EFI) System
The EFI system is a complete, electronicallycontrolled, 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.
*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 24.
Troubleshooting
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:
Fuel Rail
Low Idle Speed
Adjusting Screw
• Make sure the fuel tank is filled with clean,
fresh gasoline, and shut-off valve (if so equipped)
is opened completely.
• 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.
• 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
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).

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 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
To empty the system, run the engine until the
tank and fuel system are empty.
Major repair information is available in Kohler Engine
Service Manuals. This type of repair generally
requires the services of a trained mechanic and the use
of special tools and equipment. Kohler Engine Service
Dealers have the facilities, training, and genuine
Kohler replacement parts necessary to perform this
service.

• visit our website www.kohlerengines.com
• call 1-800-544-2444 (U.S. & Canada)
• look in the yellow pages under Engines-Gasoline
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.

Kohler Co. warrants to the ultimate purchaser and each subsequent purchaser that the engine will be designed, built and equipped, at
the time of sale, to meet all applicable regulations. Kohler Co. also warrants to the initial purchaser and each subsequent purchaser,
that the engine is free from defects in materials and workmanship which cause the engine to fail to conform with applicable
regulations for a period of two years.
Small off-road engines produced in 2006 or later, and Class 1 LSI engines produced in 2002 and later, are warranted for two years
in California. For 1997 and later model years, EPA requires manufacturers to warrant engines for two years in all other states. These
warranty periods will begin on the date the engine is purchased by the initial purchaser. If any emission related part on the engine is
defective, Kohler Co. will replace the part at no cost to the owner. Kohler Co. is liable for damages to other engine components
caused by the failure of a warranted part still under warranty.
Kohler Co. shall remedy warranty defects at any authorized Kohler Co. engine dealer or warranty station. Warranty repair work
done at an authorized dealer or warranty station shall be free of charge to the owner if such work determines that a warranted part is
defective.

modifications not recommended or approved in writing by Kohler Co.,

MAINTENANCE AND REPAIR REQUIREMENTS
The owner is responsible for the proper use and maintenance of the engine. Kohler Co. recommends that all receipts and records
covering the performance of regular maintenance be retained in case questions arise. If the engine is resold during the warranty period,
the maintenance records should be transferred to each subsequent owner. Kohler Co. reserves the right to deny warranty coverage if
the engine has not been properly maintained; however, Kohler Co. may not deny warranty repairs solely because of the lack of repair
maintenance or failure to keep maintenance records.
Normal maintenance, replacement or repair of emission control devices and systems may be performed by any repair establishment or
individual; however, warranty repairs must be performed by a Kohler authorized service center. Any replacement part or service that is
equivalent in performance and durability may be used in non-warranty maintenance or repairs, and shall not reduce the warranty
obligations of the engine manufacturer.
