6.7 TROUBLESHOOTING SEAT LOOSE OR WOBBLY
SEAT WOBBLY OR LOOSE
POSSIBLE CAUSES:
1) The seat rollers are loose or mispositioned.
2) The seat rollers have developed flat spots.
SOLUTION:
1) Tighten the seat tension by adjusting the rollers.
a. Loosen the nylok nuts putting tension on the roller brackets (Figure A).
b. Starting at the front set of brackets, use a screwdriver to leverage the roller bracket tightly so the chamfered roller is pushed toward the bottom of
the running track, and the flat roller is pushed towards the top of the running track (Figure B).
c. While holding pressure with the screwdriver, fully tighten the nylok nut to hold the roller bracket in place (Figure C).
d. Once the front roller brackets are tight, repeat procedure with the rear roller brackets.
e. Once the roller brackets are tightened, test the seat movement for smooth travel. NOTE: If the seat sticks or is hard to move, the pressure on the
roller brackets may need to be loosened. If the seat is still wobbly or loose, the pressure on the roller brackets may need to be further tightened.
2) If seat is still wobbly or loose once the roller brackets are tightened, replace the roller brackets.
