Transit
NOTE: The new backrest assembly, standard and transit, uses new backrest tubes. If the chair does
not already have the new backrest design, new backrest tubes are needed as the old tubes are not
compatible.
1. Remove any cushion or seating components that may be in the way of the current backrest removal.
Also, remove any backrest tubes and/or handles that may be used after the backrest installation
process.
NOTE: Refer to parts manual for additional information on compatibility restrictions for the new
backrest design.
2. There are two types of backrests. Use the image below to determine the version you have. For an
original backrest, remove three bolts (E, F & I), three saddles (C & J), four washers (B, H & L) and three
nuts (A, K & M) from back plate (D) to remove the back post using a 4mm Allen wrench, an 8mm
wrench and a 10mm wrench. Twist off the cable housing to detach cable from back plate. Repeat on
opposite side. For a new backrest, remove three bolts (E & F), one washer (B), four saddles (C & H), one
saddle back (G) and three nuts (A & I) using a 4mm Allen wrench, a 5mm Allen wrench, an 8mm wrench
and a 10mm wrench. Remove the screw (D) from the backrest release bar using a Phillips screwdriver
and repeat on opposite side.
3. Install new backrest by installing pivot (F) into new backrest tubes and securing with bolt (E), back plate
(D), two saddles (C), washer (B) and nut (A) using a 5mm Allen wrench and an 8mm wrench. Repeat on
opposite side.
