Using the Bessey ST125 telescopic drywall support is a breeze. First, decide on the length you need for your drywall project. You can use the telescoping inner pipe to do a rough pre - setting. Just pull it out or push it in to get close to the right length and then quickly lock it. After that, turn the support at the foam grip to do the final clamping. This way, your drywall will be firmly supported. Remember, the maximum load it can handle is 150 kg, but this depends on the size of the support and how much of it is extended. So, don't overload it. When using it on slopes, take advantage of the swivel - able contact surfaces which can move from - 45° to + 45°. For maintenance, keep it clean. Wipe off any dirt or debris regularly. Store it in a dry place to prevent the steel pipes from rusting. If you notice any issues with the locking mechanism or the contact surfaces, check the manual for troubleshooting steps or contact the manufacturer.
