V. SET UP & USE OF YOUR WHEELCHAIR
T. Drum Brake
1. Brake Operation
a. Squeeze brake levers (Fig. 44:A) on both sides of
chair to activate brakes. Each side is operated
independently and may be squeezed with more or
less force to get more or less braking action.
b. Let go of brake levers to release brake.
c. For parking brake function, squeeze each brake
lever and, with trigger squeezed, use index finger to
flip locking lever (Fig. 44:B) down into teeth on lever
mount. While holding locking lever down, release
brake handles and parking brake will remain
engaged.
d. To release parking brake, squeeze brake levers until
spring loaded locking levers snap back. Release
brake levers to deactivate the brake.
2. Brake Adjustment
a. Using a 10mm wrench, unlock jam nut (Fig. 45:A)
on adjuster (Fig. 45:B). Unthread adjuster to get
tighter braking action or thread adjuster in to
reduce braking action.
b. It is recommended to adjust the brake until there is a
slight bit of drag on the wheel when spun. Then
thread the adjuster inward about ½ turn, or whatever
is necessary to remove all drag from the spinning
wheel.
c. Retighten jam nut to lock the adjustment in place.
Repeat for opposite side of chair.
3. Axle Sleeve Position Adjustment
a. Remove both wheels. Using a 24mm wrench, loosen
axle sleeve nut (Fig. 46:A) and washer. Repeat for
opposite side of chair.
b. Move both brake assemblies to desired position.
c. Replace axle sleeve washer and nut and tighten nut.
d. Drum brake cables may need to be adjusted after
repositioning axle sleeve.
e. Caster wheel position will also need to be adjusted
the same amount as the axle sleeve. Ensure that,
when seat frame is at 0°, the seat height, as mea-
sured at the front of the chair, is within ¼" of the
seat height as measured at the rear of the chair.
Adjust caster or axle sleeve as necessary.
NOTE: Axle sleeve spacing may not be adjusted with
drum brake option.
