Important safety information
This is the safety alert symbol. It means ATTENTION! BECOME ALERT! YOUR SAFETY IS
INVOLVED! It will direct your attention to information that concerns your safety.
Read and understand all safety information in the machine operator's manual before
continuing with these instructions.
Most personal injuries are the result of failure to observe basic safety rules and precautions. In most cases,
an injury can be avoided by recognizing hazardous situations before an injury occurs and taking appropriate
action to remove or avoid the hazard.
The person installing this kit must have the necessary training, skills, and tools.
WARNING:
To avoid personal injury and/or machine damage, do the following before starting to
install this kit:
• Use personal safety equipment appropriate to the task such as:
Protective eye wear
Gloves
Steel-toed shoes
Hearing protection
• Park the machine on a solid level surface.
• Disengage the power take-off (PTO), if equipped.
• Put the transmission in the parking position and apply the park brake.
• Turn off the control console.
• Stop the engine and take the key with you.
• Look and Listen! Make sure all moving parts have stopped.
• Put blocks in front of and behind the machine wheels before working on or under the machine.
• Remove or relieve all sources of stored energy such as:
Disconnect the battery
Relieve hydraulic or fuel pressure
Relieve air pressure
Relieve or block mechanical spring pressure
Properly block or lock pivoting joints
• Clean oil, dirt, and crop material from the area on the machine where the work is to be done.

Prepare for assembly
WARNING:
Components can be heavy. Severe injury can result from improper lifting technique. Use
appropriate lifting equipment for heavy components.
Read this section carefully before assembly. Refer to the Parts Catalog for additional component
illustrations while assembling the machine.
Part numbers are shown on labels on the parts.
Hardware numbers are shown on labels on the hardware or on the container the hardware is in.
Carefully remove all the parts and hardware included. Make sure nothing was damaged or missing.
Tighten all hardware according to standard torque values unless specified in these instructions. See the
torque charts in this publication for more information.
Always replace hardware with the same grade or class.
Use all the nuts and bolts in the correct locations. This will prevent damage to the machine.
IMPORTANT: When two or more bolts are being used on a part, always insert the bolts and loosely
tighten the nuts. Once the correct location has been reached, tighten the nuts evenly to prevent
misalignment or distortion of the parts. Tighten all U-bolt nuts evenly and to the same torque to prevent
misalignment or distortion.
Select a large, flat, and hard surface for assembly of machine.
IMPORTANT: Keep all parts in the assigned containers until the parts are to be used.
NOTE: Some items will be assembled at the factory.
Right-hand and left-hand, as used in this manual, are determined by facing the direction the machine will
travel when in use.
Service parts
The illustrations and part numbers in this publication are supplied for component identification only when
assembling the machine. When ordering replacement parts, always use the part numbers from the parts
catalog.
