WARNING:
 Push auto-idle switch (3) to turn A/I display (2) OFF.
If the machine is operated with A/I display (2) ON, it
may cause the engine speed to suddenly change.
 The engine speed changes at the muffler filter
regeneration. Set the muffler filter manual
regeneration switch to the inhibition position.
 Always select the slow speed mode with the travel
mode switch.
Make sure that travel mode display (1) on the
monitor is " ".
 Never steer while driving up or down a ramp as it is
extremely dangerous and may cause the machine to
turnover. NEVER attempt to change directions whilst
positioned on the ramp. 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 as
the balance may be lost.
 Extreme care must be taken when swinging the
upper structure when the machine is on the truck
flatbed. If the front attachment is fitted, swing slowly
with the arm fully roll-in underneath the boom being
careful not to loose the balance of the machine.
