The chime tone may be affected by the hammer resting on the chime rod (coil) or striking the rod (coil) off center. Although the hammers were set at the factory, it is possible for the hammers to get out of adjustment.
Chime hammer arms are made of brass and can be bent safely. This is accomplished by bending the hammer arms slightly in the middle so that the hammers rest approximately 1/8 inch from the chime rod. DO NOT bend the chime rod. Strike volume cannot be adjusted.
