IV. WHEELCHAIR USE & CONFIGURATION
L. Drum Brake
How to Use Your Drum Brakes
1. Using the Drum Brakes
a. Squeeze the brake levers (Fig. 20:A) on both sides of the chair to activate the 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 the brake levers to release the brake.
c. For the parking brake function, squeeze each brake lever and, while trigger is squeezed,
use your index finger to flip the locking lever (Fig. 20:B) down into the teeth on the lever
mount. While holding the locking lever down, release the brake handles and the parking
brake will remain engaged.
d. To release the parking brake, squeeze the brake levers until the spring loaded locking
levers snap back. Release the brake levers to deactivate the brake.
2. Adjusting the Drum Brakes
a. Use a 10mm wrench to unlock the jam nut (Fig. 21:A) on the adjuster (Fig. 21:B). Unthread
the adjuster to get tighter braking action or thread the adjuster in to reduce the braking
action.
NOTE: The recommended brake configuration will have a slight bit of drag on the wheel
when spun. Thread the adjuster inward about ½ turn, or whatever is necessary to remove
all drag from the spinning wheel.
b. Retighten the jam nut to lock the adjustment in place. Repeat on the opposite side of the
chair.
