2. IMPORTANT
NOTES
The LMI is an operating aid that warns the crane operator of imminent overloading or of the approach
of the hook block to the boom head, in order to avoid possible property damage or injury to personnel.
The device is not, nor is it intended to be, a substitute for good operator judgment and/or experience,
nor does it remove the need for utilizing only recognized safe procedures during crane operations.
The crane operator continues to bear ultimate responsibility for safe operation of the crane.
He must ensure that he fully understands and follows the displayed notes and instructions
in their entirety.
Before beginning crane operations, the crane operator must carefully read and understand
the entire manual in order to ensure that he is aware of the operation and limitations of both
the LMI and the crane itself.
Proper functioning is dependent upon proper daily inspection and observation of the
operating instructions set forth in the manual.
The LMI is not able to provide aid to the crane operator unless it has been properly adjusted
and unless the correct load capacity chart and the correct operating code have been
entered for the respective rigging configuration. The correctness of the LMI settings must
be guaranteed before beginning crane work in order to avoid damage to property and
severe or even fatal injuries to personnel.
This system can be equipped with an external key-operated switch located in the crane
operator's cab. This key-operated switch overrides control lever function switch-off by the
LMI or by the hoist limit switch system. This switch may only be used during emergency
situations, and even then only by authorized personnel. Failure to observe these
instructions could result in damage to property and severe or even fatal injuries to
personnel.
The LMI cannot perform correctly unless it has been properly adjusted. The prerequisite for this is
making conscientious and correct entries during the set-up procedure, in accordance with the actual
configuration of the crane. The correctness of the LMI settings must be ensured before beginning
crane work in order to avoid damage to property and severe or even fatal injuries to personnel.
