5. Preparation for use

The preparation for use of these devices must be performed by qualified personnel to ensure the specific suitability of the product for the user and the correct working order of all parts and accessories, as well as to provide clear instructions to the user.

5.1. Opening/folding the backrest

EOS3 wheelchairs are equipped with a foldable backrest, with a mechanism that locks both in the opened and closed position, to facilitate transport and reduce space when not in use.

OPENING: Pull the cord to unlock the backrest and rotate it upwards until it reaches the locking position. You should hear an audible click.

Opening the foldable backrest

CLOSING: Pull the cord to unlock the backrest and rotate it downwards until it reaches the locking position. You should hear an audible click.

Closing the foldable backrest

If necessary, it is possible to adjust both the open and the closed angle of the reclining backrest (for example, to accommodate for a postural system).

5.2. Rear wheels release and re-engagement check

Verify proper operation of the quick-release axle devices before using the wheelchair.

Make sure the brakes are released
Holding down the quick-release button (in the centre of the hub), slide the wheel out of the bush
Still holding down the button, reinsert the wheel into its seat and release the button, making sure it has returned to its home position. It should click audibly when in seat
Check the working order of the engagement by trying to pull the wheel outward without pressing the button, making sure the wheel is correctly locked

Wheel removal check

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.

5.3. 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:

7.5 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

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.

5.4. Brakes check

To check the correct functioning and the efficiency of the parking brakes:

activate the brakes (ON position)
check if the wheels are locked in place

Brake type availability is limited depending on the chosen configuration. Not all brake types are available for every setup.

The included brakes, except for the assistant-activated brakes (drum), must be used exclusively as parking brakes and never as service brakes.

To ensure the efficiency of the brakes it is necessary to maintain the proper tyre pressure and check the wear of the clamping elements frequently.

5.5. Accessories check

Some accessories required when setting up the device may be supplied separately. You must assemble them and check their operation before you start using the device.

6. Accessories

EOS3 can be configured with different accessories, described in the following paragraphs.

6.1. Armrests

EOS3 wheelchairs can be equipped (with some limitations) with:

tip-up height adjustable L armrest (to be used with side-guards fixed to the frame)

L Type, tip-up and height adjustable armrest

Bracciolo a L ribaltabile e regolabile in altezza

Open or closed armrests (not height-adjustable) are available in two heights: 22 or 27 cm

All armrests are supplied in a tip-up and removable version.

Conflicts caused by particular configurations may affect the choice of armrests. It is anyways always possible to disable armrest tilting.

The armrests are not designed to lift the wheelchair, either with or without a user.

6.1.1. L type armrest, tip-up and height adjustable

Unless specifically requested, the standard height of the armrest from the seat is 220 mm. However, it is also possible to increase or decrease it by 20 or 40 mm after the order has been placed.

To adjust the height of an L type armrest:

Remove screw B.
Select the desired height (the support insert is pre-drilled in 20 mm steps) and reinsert the previously removed screw B.
Tighten screw B appropriately.

L-armrest height adjustment

If provided by the selected configuration, it is possible to tilt the armrest backwards and extract it.

Tilting the L-shaped armrest

6.2. Anti-tip device

Picture 2: Wrap the pelvic band around the tube as in the picture

6.4. Spokes guards

Spokes guards on the rear wheels serve as an esthetic feature as well as protection against accidental insertion of the user’s fingers or hands between the spokes of the wheels. They can be attached to the spokes with velcro or clips depending on the specific model.

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 5.2, “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 [replace_bearings_fork]).
✓ 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.

Only choose original parts when purchasing accessories or spare parts.
Contact OFFCARR if you can’t find original spare parts on the market elsewhere.

It is recommended to refer only to authorized and qualified personnel to perform maintenance programs, adjustments, and to replace components or accessories.

7.1. Replacement of tyre and inner tube

7.1.1. Removing the tyre and inner tube

7.1.2. Assembling the inner tube and tyre

Insert the (partially deflated) bladder into the tyre (fig. 5)
Insert the chamber inflation valve into the hole on the rim.
Insert one side of the tire entirely on the rim, paying attention to the direction of the tire tread pattern depending on whether the push wheel is right or left.
Insert the opposite shoulder on the rim as well, starting from the point where the valve is positioned and continuing in both directions.
Insert the last part of the shoulder with the help of the special levers by following the instructions represented in Fig. 3, Fig. 2 and Fig. 1 backwards.
Inflate the wheel to the pressure indicated on the side of the tyre.

Tyre/tube assembly

7.2. Replacing front wheels

If necessary, the front wheels can be replaced:

Unscrew one of the screws D and remove the pin E, paying attention to the positioning of the spacers R
Replace the wheel W
Position the wheel hole in line with the selected hole on the fork F
Insert the axle E respecting the original position of the spacers R
Tighten the screw D

Sostituzione ruotina anteriore

It is important to select the same position for both wheels. Asymmetrical positions produce instability.

Once the front wheel has been changed, it is essential to check or adjust the fork perpendicularity to the ground.

7.3. Replacing rear wheel bearings

Disassembly

The bearings in the push wheels (B1 and B2) are press-fit. To extract them it is necessary to push them from the inside with the aid of an extractor or a pin punch and a hammer.

Assembly

Position the new bearing B1 on the inside of the hub so that it is coaxial with the hub and apply pressure to seat it.
Before positioning the second bearing B2 insert the axle A to use it as a guide for the second bearing and to ensure coaxiality of the system.

7.4. Replacing front wheel bearings

Disassembly

The bearings in the front wheels (C1 and C2) are press-fit. To extract them it is first necessary to remove the wheel W from the fork F, by unscrewing the screw D and removing the pin E, taking care of not losing the spacers R.
Push the bearings from the inside out with the aid of an extractor or a pin punch and a hammer, making sure not to lose the spacer S placed inside the wheel.

Sostituzione dei cuscinetti della ruota anteriore

Assembly

Repeat the steps in the inverse order, making sure to put all spacers back where they were initially and ensuring bush coaxiality.

7.5. Quick extraction devices

7.5.1. 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

7.5.2. 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.

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.

8. Cleaning instruction

Cleaning and disinfection procedure have to be performed exclusively by qualified personnel.

Follow the instructions on this manual to perform the cleaning and disinfection procedure.

Use appropriate eye/facial protection and protective gloves, during cleaning and disinfection procedure.

In case of contamination with blood or other body fluids, the device has to be cleaned first and then disinfected as follows:

Most of the time is convenient and more effective to remove the upholstery from the frame before to proceed with the cleaning and disinfection of either frame or upholstery.

FRAME

Wash the device with lukewarm water and neutral detergent using a damp cloth to remove gross soiling
Remove eventual detergent residuals only with lukewarm water
Dry the device prior to further processing
Visually inspect the cleanliness of the complete device

Recycle or disposal of all materials must be in compliance with the local applicable laws.

Contact your dealer in case of doubt or for help when disposing the device.

13. Adjustments

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

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

13.1. Gravity centre (COG) adjustment

The choice of the centre of gravity is always a compromise between agility and safety. With a very active configuration, the wheelchair is very agile in pushing but requires greater skill in control. A more cautious centre of gravity increases the stability of the device at the expense of its agility.

It is an individual choice linked to the general configuration of the device, the anatomy and disability of the user, and the usage environment; a choice that determines the experience of pushing and inevitably influences daily activities.

The opportunity to vary this parameter over time allows the device to accompany the user’s motor development, optimizing their potential.

Consider that the further forward the hub is mounted, the more agile the wheelchair, while the further rearward the hub is mounted, the less active the set-up is to the benefit of safety; advancing the rear wheel with respect to the backrest axis, minimises the pushing effort and gives greater agility and smoothness to the wheelchair but reduces its safety margins against backward imbalance.

The advancement of the rear wheel in relation to the axis of the backrest minimises the pushing effort and gives the wheelchair greater agility and smoothness, but reduces its safety margins against backward imbalance, particularly on climbs.

If the distance between the hub centre and the projection of the backrest is reduced, the wheelchair is less active but assumes a more cautious stance.

Make sure you have chosen the same position for the wheel bushes on both sides of the frame. Asymmetrical combinations produce instability.

13.2. Backrest tilt adjustment

13.3. Brakes adjustment

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:

13.4. Front seat height adjustment

13.5. 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

13.6. 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 13.5, “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.

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

13.7. 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
Raise or lower the push handle to the desired position
Tighten the lever B correctly
Position the lever B in a convenient position

Pushing handles adjustment

To change the rest position of the lever B, pull it slightly outwards to release its engagement and rotate it to the new position.

The clamp that connects the pushing handle to the wheelchair frame can be rotated around the backrest tube. If necessary, unscrew the safety screw D before turning the screws C to loosen the clamp and allow it to rotate. Once the bracket is secured in its new position, tighten the C screws and then the D safety screw appropriately.

13.8. Footrest height adjustment

The telescopic footrest support is inserted into the front of the frame and secured through a screw and nut couple E for each side of the frame.

13.9. 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:

13.10. Pushrim with rivets
