Motor Speed Operation
WARNING! Tip Hazard. Do not operate the
crane at high speeds. Decrease the speed at
the beginning or near the end of an operation.
Change the speed to low or high according to
the load.
NOTICE: The motor speed can be adjusted by
using the travelling operation unit when travelling,
by using the monitor during crane and outrigger
operation, and by using the radio remote control
transmitter when operating under radio remote
control.
Travelling operation unit (only when
travelling)
Operate the motor speed adjuster dial as follows:
• MIN: Turning the dial counterclockwise (to the
left) reduces the motor speed.
• MAX: Turning the dial clockwise (to the right)
increases the motor speed.
Fig. 4-158
NOTICE: Release your hand from the dial once
the motor speed has increased to that required for
the task. The dial will remain at that position.
