10.1 Replacing/Adjusting the Wheel Locks

￿ WARNING

If wheel locks DO NOT hold the occupied wheelchair in place contact a qualified technician - otherwise injury or damage may occur.

For this procedure, refer to FIGURE 1 on page 64.

Before adjusting or replacing wheel locks, ensure that the tires are inflated to the recommended psi on the sidewall of the tire.

Replacing the Wheel Lock

1.Loosen the two mounting screws and remove the existing wheel lock from the wheelchair.

2.Using the two mounting screws, install the new wheel lock. Securely tighten.

Adjusting the Wheel Lock

1.Engage the wheel locks.

Any wheel lock adjustment should embed the wheel lock shoe at least 3/16-inch into the pneumatic tire (1/8-inch for urethane wheels) when engaged.

2.If necessary, loosen the two mounting screws that secure the wheel locks to the wheelchair frame and adjust position of the wheel lock until the 3/16-inch (1/8-inch for urethane wheels) measurement is obtained for correct wheel lock adjustment.

3.Securely tighten the two mounting screw(s).

4.Engage the wheel locks and push against the wheelchair and determine if the wheel locks engage the tires enough to hold the wheelchair.
