Adjusting Patient-Operated Wheel Locks - Invacare Tracer SX5 Owner's Operator And Maintenance Manual

SECTION 9—ANTI-TIPPERS/WHEEL LOCKS

Adjusting Patient-Operated Wheel Locks

NOTE: For this procedure, refer to FIGURE 9.5.
DO NOT attempt to stop a moving wheelchair with the wheel locks. WHEEL
LOCKS ARE NOT BRAKES.
NOTE: If wheels are pneumatic, before adjusting the wheel lock assemblies, ensure that the tires
are inflated to the recommended psi on the side wall of tire.
1. Ensure the wheel lock is in the open (unlocked position).
2. Loosen the bolt and locknut that secure the wheel lock assembly to the wheelchair
frame.
3. Reposition the wheel lock so that when engaged, the wheel lock shoe embeds the tire
1/8-inch (3/16-inch for pneumatic tires) and holds the wheelchair.
4. Securely tighten the bolt and locknut securing the wheel lock to the wheelchair frame.
5. Engage the wheel lock.
6. Measure the distance the wheel lock is embedded into the tire as shown in Detail ʺAʺ
of FIGURE 9.5.
NOTE: Any wheel lock adjustment should embed the wheel lock shoe at least 1/8-inch (3/16-inch
for pneumatic tires) into the tire when engaged.
7. Repeat the steps 1-6 until the wheel lock shoe embeds the tire 1/8-inch (3/16-inch for
pneumatic tires) and holds the wheelchair.
8. Repeat STEPS 1-7 for the opposite wheel lock.
9. If the measurement of 1/8-inch
(3/16-inch for pneumatic tires) cannot
be achieved, remove the bolt and
locknut that secure the wheel lock to
the wheelchair frame and mount the
wheel lock in one of two mounting
positions.
10. Repeat steps 1-9 until the wheel lock
holds the wheelchair. If the correct
measurement still cannot be achieved,
contact a qualified technician.
WARNING
If wheel locks do not hold the occupied
wheelchair in place, contact a qualified
technician; otherwise injury or damage
may occur.
