PROBLEM: The crosswalk arms squeak during use
SOLUTION: a. (Note: Correcting this problem requires a small
amount of white marine grease, available at hard-
ware stores.) Turn the Resistance Knob (A) coun-
terclockwise and remove it. Next, remove the
Resistance Cone (B) and the Crosswalk Arm (76),
along with the Resistance Plate (C), Washers (D),
Spring Washer (E), Thrust Washers (F), and Thrust
Bearing (G). (Note: If the Resistance Plate [C]
comes out of the Resistance Cone [B], press it
back in.) Apply a thin layer of white marine grease
to the outer surface of the Resistance Cone (B).
Then, reattach all parts in the order shown at the
right.
