FEDERAL and CALIFORNIA EMISSIONS WARRANTY

WARRANTY STATEMENT

IHI Shibaura Machinery Corporation (ISM) warrants that your 2004 and later non -road diesel engine was designed, built and
equipped to conform to applicable U.S. Environmental Prot ection Agency (EPA) and California Air Resources Board (CARB)
regulations and is free from defects in materials and workmanship which cause it to fail to conform with such regulations, for the
following period of operation:

● For a period of two (2) years or 1,500 hours of operation, whichever occurs first, after the date of delivery to the initial

retail owner of any variable speed non-road diesel engine rated at less than 19kW (25hp) and any constant-speed non-

-1

road diesel engine rated at less than 37 kW (50hp) with rated speed greater than or equal to 3,000 min

● For a period of five (5) years or 3,000 hours of operation, whichever occurs first, after the date of delivery to the initial

owner for all other non-road diesel engines.

.

WARRANTY INFORMATION

The model year, class of diesel engine, and emission application for your engine are iden tified on th e emission control infor­mation label affixed to the right hand side of your engine's timing gear case.

Any emission control system parts that are proven defective during normal use will be repaired or replaced during the war­ranty period.

The warranty repair or replacement will be performed by any Authorized Hustler Turf Dealer or the distributor of the original
equipment manufacturer, with no charge for parts or labor (including diagnosis).

As the engine owner, you are responsible to perform all the required maintenance listed in your owner's manual.

ISM will not deny an emission warranty claim solely because you have no record of maintenance; however, a claim may be
denied if your failure to perform maintenance resulted in the failure of a warranted part. Receipts covering regular maintenance
should be retained in the event of questions and these receipts should be passed on to each subsequent owner of the engine.

It is recommended that replacement parts used for maintenance or repairs be ISM Service Parts to maintain the quality origi­nally designed into your emission certified engine. The use of non-ISM parts does not invalidate t he warranty on other compo­nents unless the use of such parts causes damage to warranted parts.

ISM wishes to assure that the emission control systems warranty is being properly administered. If you believe you have not
received the service to which you are entitled to under this warranty, you should contact your Authorized Hustler Turf Distribu­tor.

EXCEPTIONS

Please note that Emission Warranty does not cover the following:

1. Diagnosis or inspection expenses that do not result in eligible claim.

2. Consequential damage such as loss of time, inconvenience, loss of use of the engine or equipment.

3. Replacement parts used for required maintenance.

4. Conditions resulting from tampering, misuse, abuse, improper adjustment, engine alteration, use of add-on or modified
parts, use of replacement parts that are not the same in performance and durability as the approved parts, accident, failure to
use recommended fuel or oil, use of unapproved fuel or oil additives, or not performing required maintenance.

5. Damages or repair costs caused by the Owner's unreasonable delay in making the engine available for inspection and repair.

6. Replacement parts used for required or scheduled maintenance.

5. Fuel, Lubricant & Coolant

5.1 Fuel

(1) Fuel Selection

The following specific characteristics are required for the

diesel fuel.

1. Must be free from minute dust particles.

2. Must have adequate viscosity.

3. Must have high cetane value.

4. Must have high fluidity at low temperature.

5. Must have low sulfur content.

6. Must have little residual carbon.

Diesel fuels

Applicable Standard Recommendation
JIS (Japanese Industrial Standard NO. 2
DIN (Deutsche Industrie Normen) Din 51601
SAE (Society of Automotive Engi-

neers) Based on SAE-J-313C
BS (British Standard)

Based on BS/2869-1970 Class A-1

NO. 2-D

Number 1-D and Number 2-D). This blended fuel is usually
called Number 2-D also, but can be used in colder tempera­tures than Number 2-D fuel which has not been "winterized".
Check with the service station operator to be sure you get the
properly blended fuel.

Note that diesel fuel may foam during a fill-up. This can
cause the automatic pump nozzle to shut off even though your
tank is not full.

CAUTION: Do not use home heating oil or gaso­line in your diesel engine; either may cause engine
damage.

(3) Handling of the Fuel

Fuel containing dust particles or water will cause engine
failure. Therefore, the following notice must be observed.

1. Prevent dust particles or water from entering when filling
the fuel tank.
When fueling is done from an oil drum directly, keep the
drum stationary for a period of time to allow the sediment
to go to the bottom of the drum.

2. Always fully fill the fuel tank. Drain the sedimented par­ticles in the fuel tank frequently by opening the tank
drain and draining the fuel into approved fuel containers.

(2) Fuel Requirements

CAUTION: The fuel injection pump, injector or

other parts of the fuel system and the engine can
be damaged if you use any fuel or fuel additive
other than those specifically recommended by
Shibaura. Such damage is not Shibaura's responsi­bility, and is not covered by the Warranty. To help
avoid fuel system or engine damage, please be
aware of the following:
Some service stations mix used engine oil with
diesel fuel. Some manufacturers of large diesel
engines allow this; however, for your diesel
engine, do not use diesel fuel which has been con­taminated with engine oil. Besides causing engine
damage, such fuel can also affect emission control.
Before using any diesel fuel, check with the ser­vice station operator to see if the fuel has been
mixed with engine oil.
Do not use any fuel additive (other than as recom­mended under "Biocide" in this section). At the
time this manual was printed, no other fuel addi­tive was recommended. (See your authorized
dealer to find out if this has changed.)

(4) Water in Fuel

During refueling, it is possible for water (and other con­taminants) to be pumped into your fuel tank along with the
diesel fuel. This can happen if a service station does not regu­larly inspect and clean its fuel tanks, or if a service station
receives contaminated fuel from its supplier(s).

To protect your engine from contaminated fuel, there is a
fuel filter system on the engine or equipment which allows
you to drain excess water.

WARNING: The water/diesel fuel mixture is
flammable, and could be hot. To help avoid per­sonal injury and/or property damage, do not touch
the fuel coming from the drain valve, and do not
expose the fuel to open flames or sparks.
Be sure you do not overfill the container. Heat
(such as from the engine) can cause the fuel to
expand. If the container is too full, fuel could be
forced out of the container. This could lead to a
fire and the risk of personal injury and/or vehicle
or equipment damage.

(5) Biocides

Your engine is designed to use either Number 1-D or
Number 2-D diesel fuel. However, for better fuel economy,
use Number 2-D diesel fuel whenever possible. At tempera­tures less than -7°C, (20°F), Number 2-D fuel may pose oper­ating problems (see "Cold Weather Operation" which
follows). At colder temperatures, use Number 1-D fuel (if
available) or use a "winterized" Number 2-D (a blend of

In warm or humid weather, fungus and/or bacteria may

form in diesel fuel if there is water in the fuel.

CAUTION: Fungus or bacteria can cause fuel sys­tem damage by plugging the fuel lines, fuel filters
or injector. They can also cause fuel system corro­sion.

If fungus or bacteria has caused fuel system problems, you
should have your authorized dealer correct these problems.
Then, use a diesel fuel biocide to sterilize the fuel system (fol­low the biocide manufacturer's instructions). Biocides are
available from your dealer, service stations, parts stores and
other automotive places. See your authorized dealer for
advice on using biocides in your area and for recommenda­tions on which biocides you should use.

(6) Smoke Suppressants

Because of extensive testing of treated fuel versus
untreated fuel, the use of a smoke suppressant additive is not
recommended because of the greater possibility of stuck rings
and valve failure, resulting from excessive ash deposits.

5.2 Lubricant

The quality of engine oil may largely affect engine perfor­mance, startability and engine life.

Use of unsuitable engine oil will result in piston ring, pis­ton and cylinder seizure and accelerate the sliding surface
wear causing increased oil consumption, lowered output and,
finally engine failure. To avoid this, use the specified engine
oil.

(1) Engine Oil Selection

Quality better than CD grade by API classification engine

oil must be used for the Shibaura engines.

(2) Oil Viscosity

Engine oil viscosity largely affect engine startability, per­formance, oil consumption, speed of wear and occurrence of
seizure, etc.

Using lubricants with viscosity rated according to the
atmospheric temperature is important.

CAUTION:

1. Using a mixture of different brand or quality oils
will adversely affect the original oil quality; there­fore, never mix different brands or different types
of oils.

2. Don't use API, CA, CB grade and reconstituted
engine oil.

3. Engine damage due to improper maintenance, or
using oil of the improper quality and/or viscosity,
is not covered by the warranty.
