Use service class SJ rated oil or higher. Do not extend
the oil change intervals longer than recommended,
as this can cause engine damage and may void the
warranty. An API symbol on the oil container identifies
the service class and SAE viscosity grade.
See Figure 1
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.
To minimize gum deposits in your fuel system and to
ensure easy starting, do not use gasoline left over from
the previous season.
Do not add oil to the gasoline.
Do not overfill the fuel tank (C). Leave room for the fuel
to expand.
Fuel Type
For best results use only clean, fresh, unleaded gasoline
with an 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.
6
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, should not be used. 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 engines.
Other gasoline/ether blends are not approved.
Fuel Line
These engines use Low Permeation SAE 30 R7 rated
fuel lines, certified to meet emission requirements.
Standard fuel lines may not be used. Order replacement
hose through a Kohler Service Center.
Operating Instructions
Also read the operating instructions of equipment this engine
powers.
Check Oil Level
See Figures 1 , 2 , 3 , and 4
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 cool so
the oil has had time to drain into the sump.
2.
Clean the area around and beneath the dipstick or
the oil fill plug (F) before removing it. This will help
keep dirt, debris, and other foreign matter out of the
engine. See Figure 1.
NOTE:
3.
The engine may be equipped with two dipsticks
or an oil fill plug and a dipstick. These can be
placed in either hole.
Checking oil level with a dipstick (A): Unscrew
and remove the dipstick; wipe off oil. Reinsert the
dipstick into the oil fill tube and rest the dipstick on
the oil fill neck (B). Turn it counterclockwise until
the oil fill cap drops down to the lowest point of the
thread leads. Do not thread the dipstick cap onto
the tube. See Figure 2.
Checking oil level with an oil fill plug: Unscrew
and remove the oil fill plug (A). The level should
be up to, but not over, the point of overflowing the
filler neck (B). See Figure 3.
4.
5.
If the level is low, add oil of the proper type and to
the correct level. (Refer to Oil Type.) Always check
the level before adding more oil.
Reinstall the dipstick/oil fill plug (A) and gasket (B),
and tighten securely. See Figure 4.
NOTE:
Over tightening the dipstick/oil fill plug (A)
will distort the gasket (C) and may cause oil
weeping. See Figure 4.
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 above the correct level.

WARNING
Hot Parts can cause severe burns.
Do not touch engine while operating
or just after stopping.
1.
Remove the securing hardware (B) and the spark
arrestor (A).
2.
Clean the carbon deposits out of the screen using a
wire brush.
3.
Check the spark arrestor (A). Replace if damaged.
4.
Reinstall the spark arrestor (A), securing with the
hardware (B) previously removed.
Clean Air Intake/Cooling Areas
To ensure proper cooling, make sure the recoil starter
screen, cooling fins, and other external surfaces of the
engine are kept clean at all times. Check daily.
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.
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.
Carburetor Troubleshooting and
Adjustments
Carburetor adjustments should be made only
after the engine is at operating temperature.
The carburetor is designed to deliver the correct
fuel-to-air mixture to the engine under all operating
conditions. The idle mixture is set at the factory and
normally does not require adjustment.

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 that the fuel tank cap vent is not
blocked and that it is operating properly.
•Make sure the fuel shut-off valve is fully open.
•Make sure fuel shut-off valve strainer and
in-line fuel filter (if used) are clean and
unobstructed. Clean or replace as necessary.
•Make sure fuel is reaching the carburetor.
This includes checking the fuel lines and
components for restrictions or problems.
Replace as necessary.
•Make sure On/Off switch is functioning
properly.
•Make sure the air cleaner element is clean and
all air cleaner 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.
Troubleshooting
See Figure 20
NOTE:
If the engine is hard to start, runs roughly, or stalls at
low idle speed, it may be necessary to adjust or service
the carburetor. Engine must not exceed 3850 ± 100 RPM
if the high speed screw (A) is adjusted.
When problems occur, first check for simple reasons for
a problem: for example, an empty fuel tank or the fuel
shut-off valve is turned off. Additional troubleshooting
tips can be found in the troubleshooting table.
NOTE:
Do not attempt to service or replace major
engine components, or any items that require
special timing or adjustment procedures. This
work should be performed by a Kohler Engine
Service Center.

If the engine will be out of service for two months or
more, follow these storage procedures:
1.
Clean the exterior surfaces of the engine.
2.
Change the oil while the engine is still warm from
operation. (Refer to Change Oil.)
3.
The engine must be run until the fuel tank is
completely emptied, or the gasoline must be
treated with a stabilizer to prevent deterioration.
If a stabilizer is used, follow the manufacturer's
instructions. Fill the tank with fresh gasoline and
run the engine for 2–3 minutes to ensure stabilized
fuel has entered the carburetor.
To empty the system, run the engine until the tank
and system are empty.
4.
Before transporting the engine, ensure the fuel valve
(A) is in the OFF position to prevent fuel spillage.
See Figure 6.
5.
Remove the spark plug (D). Add one tablespoon
of engine oil into the spark plug hole. Reinstall the
plug, but do not connect the plug lead. Turn the
crank to rotate the engine two to three revolutions.
See Figure 1.
6.
Remove the spark plug (D). Cover the spark plug
hole with your thumb and turn the engine over until
the piston is at the top of its stroke (pressure against
the thumb is greatest). Reinstall the spark plug, but
do not connect the spark plug lead. See Figure 1.
7.
Store the engine on a level surface in a clean, dry
place. Never store the unit where there is an open
flame, spark, or pilot light such as on a water heater
or other appliances.
Transport
1.
Turn the fuel valve to the OFF position.
2.
Tighten the fuel cap.
3.
Read and follow the transport guidelines provided
by equipment manufacturer.

KOHLER CO.
FEDERAL AND CALIFORNIA EMISSION CONTROL SYSTEMS
LIMITED WARRANTY SMALL OFF-ROAD ENGINES
The U.S. Environmental Protection Agency (EPA), the California Air Resources Board (CARB), and Kohler Co. are pleased to explain the
Federal and California Emission Control Systems Warranty on your small off-road equipment engine. In California beginning in 2006,
“emissions“ means both exhaust and evaporative emissions. For California, engines produced in 2006 and later must be designed, built
and equipped to meet the state’s stringent anti-smog standards. In other states, 1997 and later model year engines must be designed,
built and equipped, to meet the U.S. EPA regulations for small non-road engines. The engine must be free from defects in materials and
workmanship which cause it to fail to conform with U.S. EPA standards for the first two years of engine use from the date of sale to the
ultimate purchaser. Kohler Co. must warrant the emission control system on the engine for the period of time listed above, provided there
has been no abuse, neglect or improper maintenance.
The emission control system may include parts such as the carburetor or fuel injection system, the ignition system, and catalytic converter.
Also included are the hoses, belts and connectors and other emission related assemblies.
Where a warrantable condition exists, Kohler Co. will repair the engine at no cost, including diagnosis (if the diagnostic work is performed
at an authorized dealer), parts and labor.
MANUFACTURER’S WARRANTY COVERAGE
Engines produced in 2006 or later are warranted for two years in California. In other states, 1997 and later model year engines are
warranted for two years. If any emission related part on the engine is defective, the part will be repaired or replaced by Kohler Co. free of
charge.
OWNER’S WARRANTY RESPONSIBILITIES
(a) The engine owner is responsible for the performance of the required maintenance listed in the owner’s manual. Kohler Co.
recommends that you retain all receipts covering maintenance on the engine, but Kohler Co. cannot deny warranty solely for the
lack of receipts or for your failure to assure that all scheduled maintenance was performed.
(b) Be aware, however, that Kohler Co. may deny warranty coverage if the engine or a part has failed due to abuse, neglect, improper
maintenance or unapproved modifications.
(c) For warranty repairs, the engine must be presented to a Kohler Co. service center as soon as a problem exists. Call 1-800-544-2444
or access our web site at: www.KohlerEngines.com, for the names of the nearest service centers. The warranty repairs should be
completed in a reasonable amount of time, not to exceed 30 days.
If you have any questions regarding warranty rights and responsibilities, you should contact Kohler Co. at 1-920-457-4441 and ask for an
engine service representative.
COVERAGE
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.
Engines produced in 2006 or 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, the part will be replaced by Kohler Co. 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.
Listed below are the parts covered by the Federal and California Emission Control Systems Warranty. Some parts listed below may require
scheduled maintenance and are warranted up to the first scheduled replacement point for that part. The warranted parts include the
following if they were present in the engine purchased:

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.
