What should not be done with an elevated boom?

When working with an elevated boom, it's important to ensure that the equipment is stable and secure to prevent accidents. Lowering the stabilizers while the boom is elevated compromises the stability of the telehandler. Stabilizers are designed to provide additional support and maintain balance during operation, particularly when the boom is extended and elevating a load. If the stabilizers are lowered while the boom is still raised, it could lead to an increase in the risk of tipping or losing control of the equipment, hence creating a dangerous situation.

On the other hand, adjusting the load, moving the telehandler, or engaging the lifting mechanism can be part of safe operational procedures when handled properly, given that the telehandler is adequately stabilized beforehand. Therefore, not lowering the stabilizers when the boom is elevated is crucial for maintaining operational safety and ensuring the integrity of both the telehandler and the load.
