Important For safety reasons it is important to repeat this test every time that for transport or maintenance reasons, the rear wheels are removed and reassembled to the frame.

5.4. Tyre pressure check

A periodical check of the tyre pressure helps to keep the device efficient and more comfortable

Verify the tyre pressure value according to the value marked on the tyre. Indicatively the maximum pressure for the most common wheels is:

  • 7 to 9 bar (700÷900 kPa - 100÷130 psi) for Schwalbe Marathon Plus wheels

  • 7.5 bar (750 kPa - 110 psi) for high pressure wheels

  • 4.5 bar (450 kPa - 65 psi) for 20", 22", 24" x 1.3/8" wheels

  • 2.5 bar (250 kPa - 30 psi) for pneumatic castor wheels

Important The pressure for the model Schwalbe Marathon Plus should always be kept from a minimum of 7 bar (700 kPa - 100 psi) to a maximum of 9 bar (900 kPa - 130 psi) to prevent damage to the lateral surface of the tyre itself.
Important With pneumatic tyres, it is recommended to reduce their pressure in the case of air transport, to avoid collateral effects of pressure variations due to altitude.

5.5. Brakes check

Example of spokes guards

7. Maintenance, inspections and controls

Weekly:

  • ✓ Check the tyre pressure. Each tyre shows on the lateral bands the maximum pressure for which they are designed. A flat tyre affects the efficiency of brakes and the agility of the wheelchair.

  • ✓ Check the efficiency of the quick-release axle (see 5.3, “Rear wheels release and re-engagement check”) and if necessary proceed with the lubrication of axle and bushes.

  • ✓ Check the tension of the backrest upholstery to maintain a comfortable position.

Quarterly:

  • ✓ Check the tightness of all the devices' screws.

  • ✓ Check the perpendicularity of the front fork support screws.

  • ✓ Check the wear of the front wheels. Solid wheels might be worn to the point of affecting the overall wheelchair front setup. In this case adjust the front fork assembly or replace the wheels (see 7.2, “Replacing front wheels”).

  • ✓ Check the efficiency of the bearings. Replace any stuck bearings if necessary (see 7.3, “Replacing rear wheel bearings”, 7.4, “Replacing front wheel bearings” and 7.5, “Replacing front fork holder bearings”).

  • ✓ Check the efficiency of the brakes and, in case, adjust them. If the knurled pin has to be replaced, consult authorised personnel.

  • ✓ Lubricate moving parts such as hinges, bearings and quick-release axles. It is suggested to use silicon oil, which is efficient and doesn’t smear.

Important Only choose original parts when purchasing accessories or spare parts.
Contact OFFCARR if you can’t find original spare parts on the market elsewhere.
Important It is recommended to refer only to authorized and qualified personnel to perform maintenance programs, adjustments, and to replace components or accessories.

Assembly

  • Place the new bearing D2 on the lower side of the plate, applying pressure and making sure that it is evenly inserted (it must be coaxial with the hub otherwise it will not enter).

  • Before positioning the bearing D1 on the opposite side, it is necessary to insert the spacer E and the fork pin F on the already inserted bearing so that the pin itself becomes the guide for the bearing. In this way the coaxiality of the hub and the two bearings is ensured.

  • Reposition and tighten the nut B, making sure that the fork is free to rotate.

  • Replace the cover A and tighten it appropriately.

7.6. Quick extraction devices

7.6.1. Check

The quick extraction axles are shipped already checked and adjusted. However, it is recommended to periodically verify the effectiveness of their operation.

  • Make sure that the X button is fully released once the wheel is correctly mounted.

  • Check the effectiveness of the latch by trying to pull the wheel outward without pressing the button and make sure it does not slip off.

Wheel removal diagram

7.6.2. Adjustment

If necessary, it is possible to adjust the axle to eliminate any play between the wheel and the frame or to complete the release of the button once the wheel is inserted.

Wheel pin scheme

  • If the quick-release button is not completely relaxed when the wheel is inserted in the frame, it is necessary to extend the useful length of the L axle by partially unscrewing the Y nut.

  • If once the wheel has been inserted into the frame, there is play between the frame and the wheel itself, it is necessary to reduce the useful length of the L axis by partially tightening the Y nut.

Note The Y nut thread has a pitch of 1 mm, therefore the unscrewing or screwing of one turn involves the elongation or reduction of 1 mm. In case of adjustment, it is advisable to proceed with successive adjustments of ¼ of a turn at a time.

13. Adjustments

The wheelchair is shipped to the customer in the setup chosen on the order form.

Considering potential setup restrictions it is still possible to perform other adjustment to hone in the wheelchair to the specific user.

Important Please refer to authorized and qualified personnel to perform the adjustments described in this manual.

13.1. Gravity centre (COG) and/or rear seat height adjustment (HALLEY)

Acting on the AwP is possible to change the height and seat rear set-up.

Important The further the rear wheels axles are assembled, the more active and agile the wheelchair becomes, but at the same time the stability is reduced. The more back the rear wheel axles are assembled, the more stable the wheelchair is, but more effort is required to push it.

  • Pull out the rear wheel from the frame by pushing the quick-release button

Regolazione del baricentro

  • if any of the five positions D available on the AwP plate are suited to obtain the new desired setup:

  • loosen and remove the B wheel bush from the AwP plate, paying attention to the spacer’s order

  • select the new position for the B bush from the five D holes available, maintaining the original sequence for spacers, washers, and nut.

  • if none of the five positions D available on the AwP plate are suited to obtain the new desired setup, it is possible to rotate the AwP plate to multiply the possible combinations of rear height and centre of gravity (COG) position.

  • loosen and remove the two C screws connecting the AwP plate to the frame

  • loosen, without removing, the fulcrum screw D to enable the rotation of the AwP plate.

  • rotate the AwP plate in the desired position

  • reseat and tighten properly the C and D screws

  • if needed, change the position of the B wheel bush as previously described.

Regolazione del baricentro
Note Consider that the further the hub is connected, the more agile the wheelchair is, and the further back it is assembled, the less active but the safest the wheelchair becomes
Important Be sure to choose the same position in both wheel bushes on the back of the frame. Asymmetrical combinations produce instability.
Important Once the position of the back wheel changes, it is essential to adjust the front fork perpendicularity (see 13.4, “Front fork support plate perpendicularity adjustment”) and the positioning of the parking brakes (see 13.5, “Brakes adjustment”) and, if necessary, of the side-guards (see 13.6, “Side-guard adjustment”).

13.2. Rear wheels camber adjustment

The camber is supplied as requested in the order form. However, it is possible to change it later by replacing the rear wheel bushes:

  • remove the rear wheels (see 5.3, “Rear wheels release and re-engagement check”)

  • unscrew and remove the A nut and C washer

  • replace the B bush with a new one of the desired camber

  • place the B bush with the camber in the correct direction and the two flat surfaces perpendicular to the ground

  • Insert the C washer and A nut keeping it loose until a fine adjustment of the wheel camber has been performed.

Camber bush replacement
Important Once changed the front wheels it is essential to adjust the front fork perpendicularity (see 13.4, “Front fork support plate perpendicularity adjustment”).

13.3. Front seat height adjustment

13.4. Front fork support plate perpendicularity adjustment

After making adjustments to the front height or replacing or repositioning the front wheels, the perpendicularity of the front fork plate, i.e. the perpendicularity of the fork pivot axis, must be checked and adjusted if necessary. This adjustment is necessary to achieve maximum steering feel and stability of the wheelchair.

  • Remove the protective cover A

  • Loosen the screws B that secure the plate

  • Choose the most convenient position of the eccentric nuts until the plate is at right angles to the ground. (to reposition an eccentric nut it is necessary to completely remove the bolt).

  • Tighten the screws B appropriately.

  • Replace the protective cover A.

Front fork support plate squareness adjustment
Note Should it prove impossible to achieve perpendicularity, it is advisable to choose the position that generates an angle immediately above 90° (as shown in the figure) in order to keep the wheelchair agile when running and changing direction.
Important

The adjustment must be carried out symmetrically on both forks. It is important to check the symmetry carefully after each adjustment.

13.5. Brakes adjustment

Important With the exception of drum brakes, the brakes provided are only suitable for parking of the aid and not for reducing the running speed.

If the position of the rear wheel has been changed, the position of the brakes must be adjusted accordingly. Wheelchairs can be equipped with pull, push, scissor or composite brakes.

To adjust the position of the brakes:

CLASSIC BRAKES (pull or push)

  • Loosen screw A that secures the brake support to the frame

  • Move the brake along the support B until the knurled pin C is about 10 mm away from the tyre

  • While maintaining the pin C parallel to the axle tube, tighten screws A

  • If the pin C appears worn on the contact area with the wheel, it can be rotated to achieve a better position or replaced

  • Check the effectiveness of the brakes (see 5.5, “Brakes check”) and if necessary, repeat the adjustment procedure

Classic brakes adjustment and maintenance

COMPOSITE AND SCISSOR BRAKES

  • Put the brake in the ON position

  • Loosen screw A

  • Move the brake along the support until it touches the tyre

  • Return the brake to the OFF position, move it towards the wheel by 3-4 mm, and then tighten screws A

  • Check the effectiveness of the brakes (see 5.5, “Brakes check”) and if necessary, repeat the adjustment procedure

Scissor brakes adjustment and maintenance

13.6. Side-guard adjustment

Sideguards, if fitted, are attached to the wheelchair frame by means of screws which act on special slots that also allow for gradual adjustment.

In case of plastic side-guards, there is an aluminium reinforcement panel.

13.7. Backrest tension adjustment

The backrest tension can be easily adjusted by acting on the velcro straps:

  • Raise the flap B of the backrest cover. It is normally closed at the back but can be found closed at the front if the configuration requires it

  • Adjust the tension of the straps A by increasing or decreasing the overlap of the two flaps

  • Reseat in place the backrest fabric B

Backrest tension adjustment
Important The bands A which regulate the tension of the backrest, especially the highest one, must not be so tight as to reduce the width of the wheelchair, this is to allow for easy closing and opening of the wheelchair and not to damage its movement.

13.8. Seat upholstery adjustment and replacement

13.9. Backrest height adjustment, pushing handles adjustment

The height of the backrest is chosen when ordering, but further adjustments are possible. The backrest has a telescopic section, regardless from the chosen pushing handles model.

  • Lift up the backrest upholstery and open the tensioning straps to gain access to the screws A that secure the extensions to the frame

  • Remove screws A

  • Raise or lower the tubes to the desired height (tubes are pre-drilled every 20 mm)

  • Re-insert and secure the screws A previously removed

  • Reset the tensioning of the backrest and fold down the cover (see 13.7, “Backrest tension adjustment”)

Regolazione altezza schienale con maniglie fisse

  • In the presence of side-guards, remove the screws securing them to the frame and take off the corresponding support loop. Adjust the height of the backrest tube and then restore the position and fastening of the side-guards.

Note The same procedure can also be followed if the wheelchair has no pushing handles or is configured with height adjustable handles.

13.10. Height adjustable pushing handles adjustment

If the wheelchair is equipped with height adjustable pushing handles it is possible to adjust them:

  • Turn the lever B so as to loosen the clamp attachment
