PROBLEM: One of the upper body arms squeaks during use

SOLUTION: a. Correcting this problem requires a small amount of white marine grease, available at most hardware stores.

Turn the Resistance Knob (61) counterclockwise until it can be removed. Remove the Resistance Cone (98) and the Upper Body Arm (94), along with the 3/8” Washers (99), Spring Washer (101), Thrust Washers (100), and Thrust Bearing (91). (Note: If the Resistance Sleeve [97] comes out of the Resistance Bracket [96], press it back in.) Apply a thin layer of white marine grease to the outer surface of the Resistance Cone (98). Reattach all parts in the order shown at the right.
