Insufficient pump or relief valve

pressure.

Mechanical damage of the mast.

Hydraulic cylinders leaking or

binding.

• NEVER attempt to lift a load
heavier than the specified rating of
the truck.
• Also see “Traveling and Load
Handling,” in the Bendi IC
Operator's Manual F-580 for
additional information.
• See “Understanding Stability,” in
the Bendi IC Operator's Manual,
F-500.
