NOTE– Two-hole caster forks allow interchanging 5" and 6" casters and adjusting seat height.
1. Caster Fork Adjustment
a) Loosen the bolt (C) and remove the caster.
b) Either change caster size and/or position caster upward or downward in predrilled
holes (1 inch apart) on caster fork.

Q. CASTERS
Use a torque setting of 75 in-lbs. when adjusting the casters.
1. Caster Angle Adjustment
For optimum performance, the caster housing should always be at a 90º angle to the floor
(perpendicular to the ground). This adjustment is made with an eccentric (offset) attachment bolt
mechanism.
a. To change the angle, place the chair on a flat surface (such as a table).
b. Remove the bolt and nuts from the back side of the caster plate. The caster plate is slotted at
the top and bottom for adjustment.
c. Place a large right triangle against the table surface and the front surface of the caster bearing
housing.
d. This will align the caster stem rotational axis perpendicular to the floor surface.
e. Rotate the bolts independently until they fall into position.
f. When the alignment is correct, retighten the two retaining bolts.
g. Repeat the process for the other caster.
2. Caster Reversibility (GPSA)
The caster housing is generally mounted in a forward-facing position. If additional footrest clearance is
necessary, the caster housing can be reversed. This will position the caster housing rearward to allow
more clearance.
a. To reverse the caster housing, the left housing should be mounted on the right side of the frame.
b. The right housing should be mounted on the left side of the frame.
1. Moving caster housing (GP, GPV)
a) Remove the two bolts (A).
b) Remove safety cotter and clevis pin (B).
c) Slide caster plate forward or rearward and insert clevis pin into one of three pre-drilled
frame holes.
d) Reinsert and tighten the bolts (A).
e) Replace safety cotter.
f) Repeat process for the other side.
2. Reverse Mounted (GP,GPV)
a) To reverse the caster housing, the left housing should be mounted on the right side of the
frame.
b) The right housing should be mounted on the left side of the frame.
