Using your Jet JG - 300A Grip Puller is straightforward. First, choose the right pulling capacity (3/4, 1 - 1/2, or 3 - Ton) according to your load. Connect the puller to the load securely. Then, operate the puller to lift, lower, stretch, or pull the load as needed. When using it, always make sure the double - sealed ratchet brake system is working properly to ensure your safety. Keep an eye on the zinc - coated steel parts. If you notice any signs of corrosion, clean the affected area gently. Store the puller in a dry place when not in use to prevent corrosion. Also, regularly check if it still meets the ANSI/ASME B30.21 standards. If you have any doubts about its performance, have it inspected by a professional.
