Loosen the stem bolt (A) on the right fork using an 8mm Allen wrench. Do not remove the stem bolt. Simply loosen it enough to allow the teeth on the upper and lower splines to clear one another (B). With the stem bolt loosened, the caster fork should pivot freely. Place the wheelchair on the floor so that the two rear wheels and left caster contact the floor. Place some weight in the seat towards the rear to help stabilize the chair. Place a square or pocket level against the flat surface of the fork and pivot the fork until it is vertical (square). With the fork vertical, engage the teeth of the two splines to the closest mating position. Make certain that the teeth are properly engaged and not crossed. Shine a bright light behind the mating spline teeth and check for proper teeth engagement. Tighten the stem bolt to secure the spline mating position. The stem bolt should be tightened to 20 ft-lbs to ensure that it does not loosen during use.

Record the teeth engagement position of the splines on the right fork, and adjust the left fork in a similar fashion to the same position. Reassemble both casters, and re-check that they are square.

ting-up wheel locks.
1. High-Mount Scissor Wheel Locks:

J. FOOTREST HEIGHT ADJUSTMENT

wheelchairs. Use torque setting of 88 in.-lbs. when installing anti-tip tubes.

NOTE– Use a torque setting of 100 in.-lbs. when adjusting footrest height.

To adjust the height of your footrest, loosen the two cap screws (C) on the footrest clamps. Slide the footrest up or down to the new desired height and tighten the two cap screws. Use a torque setting of 100 in-lbs (11.3 N-m). It is recommended that you maintain a minimum of 2.0 inches (5 cm) between the lowest point on the footrest and the floor. This will provide adequate clearance for uneven surfaces and prevent damage to your footrest.
