Using your GearWrench 81204P ratchet set is a breeze. First, decide which drive size (1/4 - inch or 3/8 - inch) you need for your job. Attach the appropriate socket to the drive tang. You can easily reverse the direction of the ratchet using the on/off switch, clearly marked on the head. The 6 - position flex head allows you to adjust the angle for better access to hard - to - reach fasteners. When working in dirty environments, the enclosed head design will keep dirt out, but it's still a good idea to clean the ratchets after use. Use a clean, dry cloth to wipe them down. Avoid using harsh chemicals that could damage the full - polish chrome finish. Store the ratchets in a dry place to prevent rust. With a limited lifetime warranty, you can trust these ratchets to serve you well for a long time.
