Push in the tip of the quick-release axle again and pull the axle out of the rear wheel. 3. Repeat STEPS 1-2 for the opposite rear wheel. 4. To reinstall the rear wheel onto the axle mounting plate, reverse STEPS 1-3. WARNING Make sure the detent pin and locking pins of the quick/quad-release axle are fully released BEFORE operating the wheelchair. The locking pins MUST be protruding past the inside of the rear wheel axle bushing for a positive lock. Keep locking pins clean. 5. If the locking pins are not protruding past the inside of the axle bushing or there is too much movement of the rear wheel assembly in a back and forth position, refer to ADJUSTING THE QUICK-RELEASE AXLE or ADJUSTING THE QUAD-RELEASE HANDLE in this section of the manual. NOTE: During contact activities, Invacare recommends inserting quick-release axles with the head end to the inside of the wheelchair to prevent accidental release. MVP™ & MVP jr.™ 52 Part No. 1106638
