The Gen 3 LMS system was never designed to be a weight measuring system but rather, it is a weight monitoring system, intended to create safety cutouts when the machine on which it is mounted, is pushed beyond safety limits.
When using any attachments, especially ones that have a long reach, such as a long boom or fly jib/winch,
the attachment can only be used in a horizontal position. Since there are no sensors on
the tilt head, the Gen-3 assumes the attachment is horizontal. If the attachment is tilted, the load reading will become more inaccurate as the attachment is tilted towards
vertical.
Make sure to always lift the load from the ground by raising the boom rather than tilting
the attachment head.
Furthermore, tilting the attachment head can cause pressure spikes in the
hydraulic system, affecting the pressure sensors which the Gen-3 uses to measure the
load. This results in an inaccurate load reading while the head is being tilted. The load
rating on most long reach attachments is far less than the capacity of the machine. This means that if a load is lifted which exceeds the load rating, the attachment will
break or be damaged before the rear wheels lift off the ground.

When using long reach attachments, always use in the
horizontal position. Always lift the load by raising the boom
and not tilting the attachment head. Failure to do so will result
in inaccurate load readings, which may damage the attachment
causing injury. Please keep in mind that the Gen 3 system is not a load measuring system. It was never designed to be used to measure weights. It is in fact a load monitoring system that creates cutouts as a safety feature when the telehandler is pushed beyond it's maximum capacity.
If the attachment is tilted, the load reading will become more inaccurate as the attachment is tilted towards vertical.
