WARNING:
• Always turn the auto-idle switch OFF and power
mode switch (E) or (P) when loading or unloading
the machine, to avoid unexpected speed increase
due to unintentional operation of a control lever.
• Always select the slow speed mode with the travel
mode switch.
• NEVER steer while driving up or down a ramp
as it is extremely dangerous. If repositioning
is necessary, first move back to the ground or
flatbed, modify traveling direction, and begin to
drive again.
• The top end of the ramp where it meets the flatbed
is a sudden bump. Take care when traveling over it.
• Prevent possible injury from machine tipping
while the upperstructure is rotating. Keep the arm
tucked under and rotate the upperstructure slowly
for best stability.

1. The machine direction should be as follows:
With the front attachment: Travel forward with the front
attachment at the front.
Without the front attachment: Travel in reverse, as
illustrated.
2. The centerline of the machine should be over the
centerline of the trailer.
3. Drive the machine onto the ramp slowly.
With the front attachment:
• Position the tip of arm with its flat surface resting on
the trailer. Angle of the arm to boom should be 90 to
110°.
• Rest the tip of arm on the trailer just before the
machine begins to tip forward onto the trailer. Slowly
travel forward until the tracks are firmly on the trailer.
• Slightly raise the arm. Keeping the arm tucked under,
slowly rotate the upperstructure 180°.
Without the front attachment:
• Slowly rotate the upperstructure 180°.
• Lower the tip of arm onto blocks.
