Which position is considered unsafe for operating a scissor lift?

Operating a scissor lift on uneven ground is considered unsafe because it can compromise the stability of the lift. Scissor lifts are designed to function optimally on level surfaces, as uneven terrain can lead to tipping or sudden shifts in weight distribution. This instability increases the risk of accidents or falls, making it essential to ensure that the surface is flat and stable before use. Proper setup and operation are critical for safety, and understanding the risks associated with different types of ground conditions is necessary for anyone operating these machines.
