Using the powered lift semi - electric stacker is quite simple. First, make sure the battery is fully charged. You can check the battery level using the battery level gauge. To move the stacker, use the standard pulling handle. When you need to lift or lower a load, use the powered lift feature. The Power Traction Drive System helps you move the stacker around easily. Just operate the combination throttle / direction butterfly - style controller and adjust the steering yoke according to your needs. For safety, always keep in mind the 'belly switch' which is an auto - reverse emergency feature. When it comes to maintenance, regularly check the battery and keep it charged. Inspect the parts for any signs of wear and tear. Also, note that all measurements are approximate, so there might be slight variations in the stacker's performance and dimensions. Different models have different capacity limits at specific raised heights, so always check the model's specifications before use.
