Using the Kenco ML12K14T88V1 Multilift is straightforward. First, attach it to your lifting - capable machine using Kenco’s recommended Rigmax. If you need to grip from the outside, use the lever to adjust the grab within the 14 - 88 inches range. For inside - out gripping, reverse the legs and adjust within the 38 - 112 inches range. When using it on a sloped surface, rely on the specially engineered pads that pivot in all directions. As for maintenance, regularly check the pads for wear and tear. Also, keep an eye on the lever mechanism to ensure smooth adjustment. Make sure the Rigmax attachment is always secure before each use. If you notice any parts are damaged or not functioning properly, stop using the lifter immediately and get it repaired or replaced.
