UPPER DRIVE ARM EXHIBITS EXCESSIVE SIDE-TO-SIDE PLAY
Check if rotation lever is fully engaged (A). If so, follow next steps.
Remove rotation lever and cap by removing 2 socket head cap screws with a
4mm ALLEN KEY WRENCH. Loosen (do not remove) upper set screw (B) on
upright frame with a 3mm ALLEN KEY WRENCH.
Replace rotation lever, and release rotation cam mechanism (C). Rotate
cam plate (D) counterclockwise 1/8 of a turn and then engage rotation cam
mechanism. Repeat until the upper drive arm is held rigidly without play.
The rotation lever should require a firm force to fully engage. If the rotation
lever is too difficult to engage, reverse the previous steps.
To complete adjustment tighten upper set screw and replace rotation lever
and cap.
ROTATION LEVER POPS UP WHILE THE CYCLE IS IN USE
If the rotation lever loosens or pops up while the cycle is in use, per-
form the maintenance suggestions for “UPPER DRIVE ARM EXHIBITS
EXCESSIVE SIDE-TO-SIDE PLAY”
EXCESSIVE PLAY IN PIVOTING HEIGHT ADJUSTMENT LEVER
It is normal for the lever to exhibit a small amount of play before the upper
drive arm is disengaged, but if the lever has excessive play (E) or the lever
is pulled to its full extent and there is a pronounced clicking noise when
the upper drive arm is rotated, then follow the next steps.
Remove the RIGHT crank arm by removing 5 socket head cap screws with a
4mm ALLEN KEY WRENCH then remove the upper outside plastic cover by
removing 5 socket head cap screws with a 3mm ALLEN KEY WRENCH.
