REMOTE CONTROLS
General
See Figure 3-29 for more information.
This topic identifies and describes operation of the remote
controls used for crane setup, jacking, and remote engine
start. Disregard any control your crane is not equipped with.
The setup and jacking remote controls are stored on
brackets behind the enclosure on the right side of the crane
(see View C). The remote start controls are located on the
junction box near the batteries on the right side of the crane
(see View D).
To use the remote controls (setup, jacking, and engine start),
the cab power switch must be turned on in the operator’s
cab. The electric cord from the setup and jacking remote
controls must be connected to the junction boxes (see Views
A and B).
NOTE: The swing and travel alarm will sound continuously
when a function is being operated with any of the
following remote controls:
• Setup
• Jacking
•MAX-ER
The controls in the operator’s cab cannot be
operated when a remote control is being used,
except that the rigging winch can be operated
using the remote while the drum is operated from
the cab.
