Unloading the Machine

NOTICE!
To prevent damage to the machine during transportation:
• Use extreme care when the machine drives over the joint area between the trailer and the
ramps.
• Avoid damage caused by unexpected movement of the work equipment.
• Maintain the boom-arm between an angle of 90° and 110°.
• Unloading the machine with the arm retracted may damage the machine.
1. Always load/unload the machine on firm, level ground
and keep a safe distance away from roads.
2. Brake the trailer properly and chock (1) the trailer
wheels. Place the ramps between the trailer and the
machine. Make sure the two ramps are on the same
level and have an angle less than 15° (2). Adjust the
distance between the ramps to match the distance
between the tracks.
3. Remove the chains or the wire ropes that secure the
machine.
4. Start the engine.
5. Push the hydraulic lockout control lever to the
unlocked (open) position.
6. Raise the work equipment and retract the arm toward
the boom. Drive the machine slowly.
7. Stop the machine when it travels over the rear wheels
of the trailer and toward the ramps.
