Instructions

  1. 1

    Turn the two rear adjustment screws to loosen the spring tension on the paddle levers until no resistance is felt when you move the levers. Without displacing the adjustment screw from the paddle arm, pull open the contact spacing on both sides of the paddle until it stops. Unscrew the bearing tension screw slightly, located in the centre on top of the paddle, until the arms loosen and wobble slightly.

  2. 2

    Turn the bearing tension adjustment screw until tight enough that you can feel rubbing while moving the levers back and forth. Back the screw out about one-eighth turn until the arms move easily again.

  3. 3

    Turn the contact screws until you achieve your preferred spacing between the contacts on each side of the paddle arms. This is purely personal preference regarding contact spacing. Turn the locking screws, located above the contact adjustment screws, clockwise to tighten once desired spacing is set.

  4. 4

    Adjust the arm tension to the minimum amount of tension that allows you to feel comfortable while controlling the paddle. Increase tension by turning the adjustment screw counterclockwise; clockwise to decrease tension.

Tips and warnings
