Quick-Release Axles


Removing

1. Hold the centre of the rear wheel and push in the tip of the quick release axle.

2. Pull the quick release axle and rear wheel out of the axle bracket on the wheelchair frame.

3. Push in the tip of the quick release axle again and pull the quick release axle out of the existing rear wheel.

4. Install new/existing rear wheel onto wheelchair. Refer to Removing/Installing Rear

Wheels paragraph.

W A R N I N G

Make sure the detent pin and locking pins of the quick-release axle are fully released before operating the wheelchair.

The locking pins MUST be protruding past the inside of rear wheel hub for a positive lock.

Keep locking pins clean.

Invacare recommends inserting quick-release axles with the head end to the inside of the wheelchair to prevent accidental release during contact leisure activities.

Installing

1. Install the existing quick release axle through the new/existing rear wheel.

2. Install the new/existing rear wheel and quick release axle into the axle bracket on the wheelchair frame.

3. Refer to Adjusting Quick Release Axles paragraph 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.

1.

Remove the wheel. Refer to Removing/Installing Rear Wheels paragraph.

2.

Remove the two mounting screws that secure the top and bottom of the axle plate to the wheelchair frame ( A, B, C & D Positions ). Remove the four mounting screws that secure the top and bottom of the axle plate to the wheelchair frame (Active Position

& Very Active Position).

C A U T I O N

The top of the axle plate must remain on the plastic seat bracket.

Otherwise, scratching and slight frame damage may occur.

3.

Align the axle plate with one of four adjustment holes. There are 4 positions possible:

•

Factory setting for Fixed backrest is Standard position “A”, for Recliner backrest is

Passive position “B”. Refer to detail “A” next page.

•

High Active position “C” and Medium position “D” (these positions are not a factory setting).

W A R N I N G

The two mounting screws need to be two adjustment holes apart to maintain frame integrity (A, B, C & D Positions).

The four mounting screws need to be four adjustment holes apart to maintain frame integrity (Active Position & Very Active Position).

Respect factory settings related to backrest type (Standard “A” for Fixed, Passive

“B” for Recliner), refer to detail “A” of FIGURE 5.6.and to seat depths (400 mm or

450 mm).

High Active position “C” and Medium position “D” (not factory settings) of the axle plates directly relate to the stability of the wheelchair. Any change to one or any combination of the 4 positions may cause the wheelchair to increase/decrease in stability.

Anti-tippers can be fitted to secure the stability if required. Refer to SECTION 9.

NOTE: When using the last adjustment position, the existing mounting screw needs to be switched to the front of the back-cane bracket.

4.

Repeat STEPS 1 to 3 for the other axle plate.

NOTE: Both axle plates should be set at the same position. Head of bottom mounting screws needs to be on the outside position.

2. To properly tighten caster journal system and guard against flutter, perform the following check:

A. Tip back the wheelchair to floor.

B. Pivot caster fork assemblies in rear position

C. Push caster to initiate clockwise movement

D. Let caster fork assembly rotate freely, if not change the upper specific bearing.

3. Adjust locknuts to appropriate torque (50/60 Nm) with a 19 mm socket wrench, do not overtight the locknut.

NOTE: Invacare recommends that the rear seat to floor height be AT LEAST 25 mm shorter than the front seat to floor height. Otherwise a forward seat angle can occur.

Subtract the rear seat to floor height measurement from the front seat to floor height measurement to determine the amount of seat angle as shown in the example in

Measuring Seat-to-Floor Height


NOTE: All measurements are in millimetres. The front and rear seat to floor heights are approximate to 6.5 mm due to tire wear and air pressure.

Measuring Front Seat-to-Floor Height

Front Seat to Floor Height: Measure the distance between the front of the seat upholstery and the ground/floor.

Measuring Rear Seat-to-Floor Height

NOTE: The rear seat to floor heights are based on pneumatic tires and pneumatic tires with flat free inserts. If wheelchair is equipped with urethane tires, subtract 6.5 mm from the measurement.

Rear Seat to Floor Height: Measure distance between the rear of the seat upholstery and the ground/floor.

Changing Seat-to-Floor Height

W A R N I N G

The seat height, seat depth, back angle, seating system, size/position of the rear wheels, size/position of the front casters, seating options (e.g. headrest, back bag, …) as well as the user condition directly relate to the stability of the wheelchair. Any change to one or any combination of these factors changes the center of gravity and may cause the wheelchair to increase/decrease in stability. Refer table on page 6.

Always check caster vertical axis is to 90° +/-1° from the ground.

NOTE: For this procedure, refer to the table to determine adjustment(s) necessary to achieve desired front seat to floor height.

NOTE: To obtain the desired front seat to floor height, it will be necessary to perform one or both following:

•

Changing the caster size and/or mounting position on the fork, and/or seat angle

Refer to Removing/Installing/Repositioning the Caster Assemblies paragraph.

•

Changing the fork size or adding/removing height adjustment spacers. Refer to
