changes can cause machines to vary from the photos and the illustrations. The manufacturer reserves the
right to redesign and change machines as necessary without notification.
WARNING:
Some pictures in this manual show the machine with shields or guards removed to
permit for a better view of the subject of the picture. All shields and guards must be in
position before operating the machine.
Machine movement when in normal use determines right-hand and left-hand.
1.1.2 Units of measurement
Measurements are given in metric units followed by the equivalent in US units. Hardware sizes are given
in millimeters for metric hardware and inches for US hardware.

divisions also have a table of contents.
1.1.4 Page numbers
All pages have two numbers, such as 01-25. The first number shows the division. The second number
shows the page in the division.
Page numbers occur on the lower right-hand or lower left-hand corner of each page.
1.1.5 Intended use
This machine is designed solely for use in customary agricultural operations.
Do not use this machine for any application or purpose other than those described in this manual. The
manufacturer accepts no liability for damage or injury resulting from misuse of this machine.

4283556M2

Keep signs clean by wiping off regularly. Use a mild soap and water solution if necessary.
If parts have been replaced or a used machine has been purchased, make sure all safety signs are present
and in the correct location and can be read. Illustrations of safety sign locations are located at the rear of
this section.
Replace any safety signs that can not be read, are damaged, or are missing. Clean the machine surface
thoroughly with a mild soap and water solution before replacing signs. Replacement safety signs are
available from your dealer.
1.2.1.5 A word to the operator
It is your responsibility to read and understand the
safety section in this manual and the manual for all
attachments before operating this machine.
Remember you are the key to safety. Good safety
practices not only protect you, but also the people
around you.
Study the content in this manual and make the
content a working part of your safety program.
Keep in mind that this safety section is written
only for this type of machine. Practice all other
usual and customary safe working precautions,
and above all remember - safety is your
responsibility. You can prevent serious injury or
death.
This safety section is intended to point out some
of the basic safety situations that may be
encountered during the normal operation and
maintenance of your machine. This section also
suggests possible ways of dealing with these
situations. This section is not a replacement for
other safety practices featured in other sections of
this manual.
Personal injury or death may result if these
precautions are not followed.
Learn how to operate the machine and how to use
the controls properly.

equipment have a separate Operator
Manual, see that manual for other
important safety information.
1.2.1.6 This manual
This manual covers general safety practices for this machine. The operator manual must always be kept
with the machine.
Right-hand and left-hand, as used in this manual, are determined by facing the direction the machine will
travel when in use.
The photos, illustrations, and data used in this manual were current at the time of printing, but due to
possible in-line production changes, your machine can vary slightly in detail. The manufacturer reserves the
right to redesign and change the machine as necessary without notification.

In some of the illustrations and photos used in this manual, shields or guards may have
been removed for clarity. Never operate the machine with any shields or guards removed.
If the removal of shields or guards is necessary to make a repair, they must be replaced
before operation.
1.2.1.7 Operator manual holder
The operator manual holder (1) holds the operator
manual.
After using the operator manual, return the
operator manual to the operator manual holder.
Fig. 4
1.2.2 Operation
1.2.2.1 Prepare for operation
Read and understand all operating instructions and precautions in this manual before operating or servicing
the machine.
Make sure you know and understand the positions and operations of all controls. Make certain all controls
are in neutral and the park brake is applied before starting the machine. Make sure the steering wheel is
centered and locked.
WARNING:
Any time the engine is running and the park brake is disengaged, the machine will turn if
the steering wheel is moved even though the travel control lever is in neutral.
Make certain all people are well away from your area of work before starting and operating the machine.
Check and learn all controls in an area clear of people and obstacles before starting your work. Be aware of
the machine size and have enough space available to allow for operation. Never operate the machine at
high speeds in crowded places.
1. General

characteristics of this equipment before you start.
1.2.2.2 General information
When parking, park the machine on a solid level
surface and lower the header to the ground. Put all
controls in neutral, center and lock the steering
wheel, and apply the park brake. Stop the tractor
engine and take the key with you.
WARNING:
Do not leave the machine unattended
with the header raised. Lower the
header fully before leaving the
machine. A sudden loss of hydraulic
pressure can cause the header to
drop without warning.
Make sure the machine is in the proper operating
condition according to the Operator Manual.
Always operate the machine with the control
console turned on.
Do not dismount from moving machinery.
Stay off slopes too steep for operation.

Stay off slopes too steep for operation. Keep the
header as low as possible while going down hills.
Never suddenly reverse the wheels to stop or back
up.
Where possible avoid operating the machine near
ditches, embankments, and holes. Reduce ground
speed when operating on rough, slippery, or
muddy surfaces and when turning or crossing
slopes.
