Using the Abaco TPS 3 - In - 1 Forklift Boom is quite straightforward. First, make sure your forklift is in good working condition. Attach the boom securely to the forklift. When you need to lift materials in a small area, use the left - right swing feature. To reach deep inside containers, extend the boom. Adjust the lifting angle as needed for large materials in height - restricted places. You can use the handwheel to lift or lower and the roller to quickly adjust the boom's left - right position. As for maintenance, regularly check the connection between the boom and the forklift. Clean the handwheel and roller to keep them working smoothly. Also, check for any signs of wear and tear on the boom. And always follow your forklift's safety guidelines when using this boom.
