What condition must be met before raising the boom of a telehandler?

Before raising the boom of a telehandler, it is crucial that the machine is level. This condition ensures the stability and safety of the telehandler during operation. A level machine reduces the risk of tipping over as it distributes weight evenly, which is especially critical when lifting heavy loads. If the telehandler is on an incline or slope, shifting weight can lead to a loss of control or balance when the boom is extended, potentially resulting in accidents or equipment damage. Therefore, ensuring that the telehandler is on a level surface is a fundamental safety requirement before performing any lifting operations.
