What can make a forklift mast lower?

A forklift mast can lower due to several factors, including operator input through the control lever, gravity when the load is removed, or a malfunction in the hydraulic system. If the operator releases the control lever, the mast will descend. Additionally, issues such as hydraulic fluid leaks or worn seals can lead to unintentional lowering of the mast. Regular maintenance is essential to prevent such problems and ensure safe operation.
