Using the MRTALP Lifter Series is easy. First, make sure the battery is fully charged. Then, adjust the position of the lift spool according to the size of the load. Place the vacuum pads on the surface of the object you want to lift. The Intelli - Grip Technology will automatically monitor the vacuum and power systems to ensure a safe lift. When lifting, be careful not to exceed the maximum load capacity. For example, the MRTALP811LDC3 and MRTALP810TDC3 can handle up to 1100 lbs [500 kg], while the Panel Master can handle up to 600 lbs [270 kg]. When it comes to load movement, you can manually rotate the load 180° edgewise and lock it every 30°. The assisted manual tilt allows a 90° movement between upright and flat, with automatic latching in the upright position. For maintenance, regularly check the battery gauge. Replace the battery when it's low. Also, clean the vacuum line filters and vacuum reserve tanks. Inspect the spring - mounted vacuum pads for any damage and replace them if necessary. Keep the machine in a dry and clean place when not in use.
