OPERATING CONTROLS
See Section 3 for identification and operation of all controls.
• The carbody controls (crawler pins and carbody jacks)
are operable any time the engine is running.
• To operate the mast as a boom using the boom hoist
handle, the crane CRANE SETUP mode must be
selected and confirmed.
• To operate the switches on the remote control
(counterweight, boom butt, etc.) SETUP REMOTE
mode must be turned ON and confirmed. The mast is
still operable in this mode.
Turn off SETUP REMOTE mode to prevent
accidental operation of remote switches when
remote control is not in use.
SHIPPING CRANE COMPONENTS
To ensure the crane’s self-erecting system can load and
unload the carbody and upperworks assembly, the trailer
must meet the specifications given in Figure 4-3.
It is the owner/user’s responsibility to ensure the following:
• That all trailer loads comply with local, state, and federal
transportation requirements.
• That all crane components are properly blocked and
secured so they cannot shift or fall off trailers.
• To avoid damage to components:
Use nylon tie-downs to secure components as shown in
Figure 4-3, View A.
If chain tie-downs are used, install protective covering
(such as sections of rubber tire) between the chain and
component being secured as shown in Figure 4-3, View
B.
When securing boom sections, wrap tie-downs over
chords — never over lacings. Keep tie-downs as close
to blocking as possible (View A) to prevent bending the
chords.
