[12] ACCELERATOR LEVER (12)
The Accelerator lever controls the flow rate of the control valves
and the engine speed or output.
• Low idling: Release your finger from the Accelerator lever.
• Full throttle: Squeeze the accelerator lever to the full.
NOTES
• The Accelerator lever itself cannot control either flow rate of the
control valves or the engine speed when it is manipulated
alone.
In the condtion that any of the other operation levers are also
used, the Accelerator lever launchs specified operation of the
Crane in the idling state of the engine, when it is manipulated,
then, the engine speeds up by further manipulation of it; the
crane operation turns to be faster, accordingly.
• The Accelerator lever does not control outriggers.
• The acceleration rate is always indicated in the right part of the
LCD screen during crane operations. (See the figure in the
right.)
