5.2 Loading
Loads must not exceed the rated capacity. Overloading can cause
damage or failure, which may lead to severe injury.
Any load that may shift during raising or lowering must be secured.
When loading the machine, the load must be centered on the platform. If the load is uneven
the heaviest part of the load is to be placed toward the mast of the machine to avoid excessive
deflection. Due to the cantilever design, some deflection will occur.
