Make sure you follow the manufacturer's instructions for proper maintenance. You should also use common sense when operating a lift table. Be sure not to overload it, as this may cause damage to the machine or injure the operator. Also, never stand on the table or put your hands under it while lowering it.
Make sure that the load is evenly distributed across the table. Make sure not to use the lift table to move loose or unstable loads. Make sure that the table is positioned on a solid surface, and do not place it on any other surfaces, as this can cause the platform to fall.
If the lift table is hydraulic, the motor controls the downward movement of the table. If the power goes out, the motor automatically stops raising the table.
