Using these Grover 102BC machine heads is easy. Just install them on your guitar using the included 5/8” washers, bushings, and wood screws. Once installed, you can tune your guitar strings by turning the machine head. If you find the turning too tight or too loose, use the countersunk tension screw to adjust the tension. When it comes to maintenance, there's not much to worry about. The gear box has a special lubricant that should last a long time, but if you notice any unusual noise or difficulty in turning after a long period of use, you can take it to a professional for a check - up. Also, keep the machine heads clean and dry to prevent any rust or damage. Avoid using abrasive materials when cleaning them.
