How To...ADJUST SEAT ROLLER ADJUSTMENT
Tools Required: Two torque wrenches, combination wrench set
1. The SEAT ROLLERS are adjusted to a specified
resistance load. If the seat moves too freely with
excessive side-to-side movement, then the seat
rollers must be adjusted as follows.
2. Using a ½ inch wrench, loosen all four(4) SEAT
ROLLER CLAMP NUTS, then retighten by hand.
3. Make initial adjustments to the SEAT ROLLERS on the
right side of the unit first. This is done to ensure that
the two right guide rollers are properly seated in the V-
channel of the seat extrusion. Once the SEAT
ROLLERS on the right side are adjusted, then proceed
to adjust the seat rollers on the left side of the unit.
NOTE: Step 4 requires use of two inch pound torque
wrenches. One to maintain a resistance load against the
TAKE-UP ROLLER and the other to torque the ROLLER
CLAMP NUT.
4. Starting with the right side SEAT ROLLERS, adjust the
first TAKE-UP ROLLER NUT to 60-65 in. lbs. in a
clockwise direction. Observe that the ROLLER CLAMP
NUT will move up. This indicates that the seat roller is
being forced up against the extrusion. Continue to
maintain the 60-65 in. lbs. resistance load on the take-
up roller, and secure the seat roller position by
tightening the ROLLER CLAMP NUT from 100-120 in.
lbs. Repeat this procedure for other remaining right
roller. Once the right side is adjusted, repeat this
procedure for the left side. Always set the right side
seat rollers first. Failure to do so, will result in side-to-
side seat movement.
5. With all SEAT ROLLERS adjusted, test operation of the
seat assembly for a 15-25 lbs. pulling force and to
insure that no side-to-side movement exists. Repeat
this procedure as required.
