Using the Abaco ASFJ27 Smart Forklift Boom is easy. First, make sure your forklift is compatible with the boom's large fork slots. Then, attach the boom to the forklift properly. If you're using it with a slab lifter, connect them securely before lifting any slabs. When operating in confined spaces, take advantage of the low - profile design. Be aware of the weight load limit, which ranges from 1,540 to 4,620 pounds. Don't exceed this limit to ensure safety. For maintenance, regularly check the telescopic parts for smooth operation. Clean the boom after each use, especially if it's exposed to dirty materials like stone dust. If you notice any damage, stop using it immediately and get it repaired or replaced.
