FEDERAL EMISSIONS WARRANTY
(North America Only)
(California owner’s emissions warranty is covered elsewhere)
CNH UK Ltd warrants that your new 1996 and later heavy-duty off-road diesel engine was designed, built, and equipped to conform to
applicable U.S. Environmental Protection Agency regulations for a period of use of five years or 3,000 hours of operation, whichever occurs
first.
The new model year, class of diesel engine, and emission application determination for your engine are identified on the emission control
information label affixed to the engine. The warranty period begins on the date the new equipment is sold to the first retail purchaser.
Any emission control system parts which are proven defective during normal use will be repaired or replaced during the warranty period. The
warranty repairs and service will be performed by any authorized CNH dealer at the dealer’s place of business, 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. CNH UK Ltd 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 replacement parts used for maintenance or repairs be CNH Service Parts to maintain the quality originally designed into
your emission certified engine. The use of non-CNH parts does not invalidate the warranty on other components unless the use of such parts
causes damage to warranted parts.
CNH UK Ltd wishes to assure the emission control systems warranty is being properly administered. If you believe you have not received the
service entitled to under this warranty, you should contact the nearest CNH Office for assistance. The address and phone number of each
Office is in your equipment owner’s manual. If additional assistance or information is needed, contact:

UK LTD recommends the use of new, genuine CNH service parts or CNH approved rebuilt parts and assemblies. CNH UK LTD also
recommends that the engine be serviced by a CNH authorized dealer.
CNH UK LTD Responsibilities:
Warranty work will be provided at no charge to the owner at any authorized dealer, using genuine CNH service parts or CNH approved rebuilt
parts or assemblies.
The owner will not be charged for diagnostic labor which leads to the determination that a warranted part is defective, if the diagnostic work
was performed at a warranty station.
CNH UK LTD is liable for damages to other engine components caused by the failure under warranty of any warranted part.
Warranty Limitations
CNH UK LTD is not responsible for failures resulting from abuse or neglect by owner or operator.
CNH UK LTD warrants to the ultimate purchaser and each subsequent purchaser that the engine is designed, built, and equipped so as to
conform with all applicable regulations adopted by the Air Resources Board, and that it is free from defects in materials and workmanship
which cause the failure of a warranted part.
Any warranted part which is not scheduled for replacement as required maintenance, or which is scheduled only for regular inspection to
the effect of “repair or replace as necessary” is warranted for the warranty period.
Any warranted part which is scheduled for replacement as required maintenance is warranted for the period of time prior to the first scheduled
replacement point of that part.
CNH UK LTD is not liable to warrant failures caused by the use of add-on or modified parts.

with and follow safety precautions.
OPERATING THE LOADER
1. The equipment owner is responsible to make
certain that all operators read this manual
thoroughly and understand the safety pre-
cautions and proper operating procedures.
Be certain all operators are qualified before
allowing operation.
2. Always check with proper authorities for
underground utilities before digging.
3. Exercise caution when operating the loader
with a raised bucket or attachment.
4. Avoid loose fill, rocks and holes. These are
dangerous conditions for loader operation or
transport.
5. Use caution when operating on steep grades.
Always carry the bucket or attachment in the
lowest possible position to maintain maxi-
mum stability. Select the proper gear
BEFORE attempting to travel on a steep
grade. Avoid shifting on grades and never
“free wheel”.
6. Be sure to allow for the length of the loader
when making turns or working in confined
areas.
7. Stop the loader arms gradually when raising
or lowering the loader.
8. Carry the bucket or attachment as low as
possible to increase visibility and stability
during transport.
9. When parked or during servicing of the
loader, lower the bucket to the ground, stop
the engine, set the park brake and remove the
key from the key switch. Special care should
be taken to park or store attachments with
sharp points or edges in a safe manner.
10. Do not operate loader controls unless
properly seated in the operator’s seat.
11. NEVER attempt to handle large, heavy
objects such as large round or rectangle
bales, logs or oil drums unless the specific
special attachments are used. Handling such
objects is not recommended without special
equipment.
12. Handling large heavy objects can be
dangerous due to the following:
•danger of overturning the tractor
•danger of upending the tractor
•danger of the object rolling or sliding
down the loader arms onto the operator
13. If the type of work in precaution # 12 must be
performed adhere to the following:
•always use the proper attachment
•never lift the load higher than necessary
to clear the ground while moving
•ballast the rear of the tractor to compen-
sate for the weight of the load
•never lift large or heavy objects with
equipment that does not have an
anti-rollback device
•move slowly and carefully, avoiding
rough or uneven terrain
14. Loader lift capacity and break-away capacity
diminish as the loader height is increased.
Use care not to grasp more material than the
loader is designed to handle.

MAINTENANCE
1. Always wear eye protection when servicing
or repairing the loader.
2. Do not modify, alter or permit anyone else to
modify or alter the loader or any of it’s
components or functions without first
consulting a Case IH dealer. Contact your
dealer with questions about the loader.
3. Escaping hydraulic fluid or diesel fuel under
pressure can penetrate the skin causing
serious injury. To prevent serious personal
injury:
•DO NOT use your hand to check for
suspected leaks under pressure
•Use a piece of cardboard or heavy paper
to search for leaks
•Stop the engine and relieve the pressure
in the system before connecting or
disconnecting hydraulic or diesel lines
and fittings
•Tighten all lines and fittings before
starting the engine and pressurizing the
system
•If any fluid is injected into the skin, obtain
medical attention IMMEDIATELY to avoid
the onset of Gangrene
