2. Using the device
|
|
To use the device correctly and safely, it is always recommended to clarify any doubts with qualified personnel. |
Hereafter are some suggestions and recommendations for a correct use of the device, also aimed at maintaining its safety and durability characteristics over time:
-
The brakes only have a parking purpose and should never be used as service brakes to slow down the device in motion.
-
To ensure the efficiency of the brakes, keep the tyres properly inflated and check the wear of the knurled locking pins every 3 months.
-
The anti-tip wheels (if present) must never be used as transit wheels.
-
Do not lean too far forward; excessively shifting the centre of gravity could cause the device to tip over.
-
Always deal with slopes above 6° with assistance from an attendant. This limit is only approximate and it depends on the configuration, in particular on the position of the centre of gravity of the user-wheelchair system.
-
The device must be used only to transport a person, not objects.
-
The armrests, if present, are not designed to lift the device.
-
Avoid wheeling the device without the supervision of an attendant.
-
Prolonged contact of the device with water or prolonged exposure to high humidity levels can cause unwanted oxidation of some metal parts and decay of the safety characteristics of the materials involved.
-
Avoid contact with seawater and sand. In case of contact, proceed with immediate and thorough cleaning.
-
Perform a general check of the device at least every three months, checking tyre inflation, the efficiency of the quick-release axles and brakes; lubricate the moving parts whenever necessary.
-
Clean the device with a damp cloth and avoid even partial immersion of the frame. Keeping the device clean increases its efficiency.
-
Suspend use of the product and notify OFFCARR in case of allergies or other similar problems due to contact with the materials that make up the device.
-
The fabric used for the device’s upholstery is washable with low-temperature water. In any case, avoid wetting or immersing other parts of the device.
-
There is no danger of causing injury to people during the operations of preparation and setup of the device, if carried out carefully following the instructions provided in this manual.
|
|
Make sure the tyres are correctly inflated. The inflation pressure depends on the tyre model; find the correct pressure shown on the tyre’s sidewall. |
|
|
Keep the device away from heat sources, as not all the components are fireproof. |
|
Upholstery materials comply with the EN 1021-2:2014 regulation. |
|
|
The approximate lifespan of the device is 7 years, considering correct, normal daily use by a single user and regular maintenance. |

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
OFFCARR 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. |
|
|
|
CLOSING: Pull the cord to unlock the backrest and rotate it downwards until it reaches the locking position. You should hear an audible click. |
|
|
|
|
|
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. |
The wheelchair is usually shipped with the rear wheels disassembled.
|
|
|
|
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
|
|
Pushing brake ON position |
Pushing brake OFF position |
|
|
Pulling brake ON position |
Pulling brake OFF position |
|
|
Scissor brake ON position |
Scissor brake OFF position |
|
|
Composite brake ON position |

|
|
Side-guards brake ON position |
Side-guards brake OFF position |
|
|
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. Footrest positioning
OFFCARR wheelchairs can be configured with detachable or not detachable footrests
According to the limits of setup, the footplate can be single or double (separate footplates). The footplates can be folded down once the wheelchair is open
The single footplate is available in manual or automatic version. The automatic version, which follows the opening/folding of the wheelchair, is available only for non-detachable footrests frames.
After opening the wheelchair, manually bring the footplates to the correct position by rotating them downward. In case of single footplate, pay special attention to the engagement of the footplate on the frame on the side opposite the fulcrum.
Separate footplates |
Single footplate |
Automatic footplate |
|
|
|
|
|
In the absence of weight, even with the wheelchair open, the automatic fooplate remains slightly raised on one side. This condition is absolutely normal and allows the automatic closing. A slight weight on the plate is enough to make it assume the horizontal position. |
|
|
In case of removable footrests frame, the footrests are packed separately. They must be assembled before use. |
To insert the footrest:
-
open the wheelchair
-
insert the footrests in their correct housing and rotate them starting from a 90° angle position from the frame (as shown) and rotate it inwards until the hooking mechanism snaps
To extract the footrest:
-
Press the lever L and rotate the footrest outwards (while maintaining the lever pressed)
-
Remove the footrest from the hinge pin by pulling it upwards
|
|
The detachable footrest can be rotated both inwards and outwards, by using the same mechanism |
5.5.1. Footplate cover
For certain configurations, the wheelchair can be provided of a metal single plate that covers the plastic/aluminium footplates. The plate anchors to the footplates with light pressure, with no special locking mechanisms. To remove it, simply lift it up; to reinsert it, it must be placed over the footplates by applying slight pressure.
|
|
5.6. Accessories check
Some accessories required when setting up the wheelchair may be supplied separately. You must assemble them and check their operation before you start using the wheelchair.
6. Accessories
OFFCARR can be configured with different accessories, described in the following paragraphs.
6.1. Armrests

7. Attachment of the wheelchair for use within a motor vehicle
Where clearly indicated, the wheelchair models successfully passed the crash test according to the specifications of ISO 7176-19:2008 and can therefore be used safely in motor vehicles.
|
|
Some configurations, while available on order form, can prevent the wheelchair from being vehicle-compatible. Contact OFFCARR for further information. |
|
|
It is mandatory that all of the approved wheelchair components are installed by authorized personnel following the correct technical specifications. |
|
|
Whenever feasible, it is recommended to use the vehicle seat and its manufacturer-installed restraint systems, storing the wheelchair in the vehicle’s cargo area or securing it in the passenger area. |
|
|
When transporting an occupant the wheelchair must always face forward and be securely anchored to the vehicle. |
|
|
The wheelchair has been tested only in a forward-facing orientation with the anthropomorphic test device (ATD) restrained by both pelvic and shoulder belts. |
|
|
In order to safely transport a wheelchair user in a vehicle, the vehicle must be provided with a Wheelchair Tie-down and Occupant Restraint System (WTORS) conforming to ISO 10542 or SAE J2249 standards, appropriately installed according to the manufacturer specifications. |
|
|
Both diagonal and lap belts must be used during transport to reduce the possibility, in the event of an accident, of impacts with other components inside the vehicle. |
|
|
Anchor the wheelchair with extreme care and follow the instructions given by the manufacturer or authorized installer of the anchoring system closely. When in doubt, consult the instructions for use or contact the installer of such system. |
|
|
Never transport an occupant sitting on a wheelchair unless the device is certified according to the requirements in ISO 7176-19:2008. |
|
|
Wheelchair-mounted trays, if installed, should be removed and secured separately in the vehicle. |
|
|
When possible, other auxiliary equipment must be either secured to the wheelchair or removed and secured in the vehicle. |
|
|
Postural systems, if installed, should not be relied on for occupant restraint in a motor vehicle, unless labelled as being compliant with ISO 7176-19:2008. |
|
|
In order to securely connext the wheelchair to a vehicle, all the anchoring points must be used. |
The anchoring points are indicated by the following label (according to ISO 7176-19 specifications) |
|
|
|
If the user is transported while sitting on the wheelchair, they must be wearing a seat belt. Any safety belts for vehicle transport must be installed by authorized vehicle conversion companies and must be serviced. |
|
Belt restraints should make full contact with the shoulder, chest and pelvis, and pelvic belts should be positioned low on the pelvis near the thigh-abdominal junction (as shown on the drawing). |
|
Belt restraints must not be held away from the body by wheelchair components such as armrests or wheels (as shown on the drawing). |
|
The pelvic belt restraint should be worn low across the front of the pelvis, so that the angle of the pelvic belt restraint is within the preferred zone of 30° to 75° to the horizontal (as shown on the drawing). |
|
|
If possible, it is recommended to use the restraints with a steeper angle of 45° to 75° from the horizontal (as shown on the drawing). |
|
|
Belt restraints should be as tight as possible, consistently with user comfort, and should not be twisted during use. |
|
|
Following involvement in any type of collision, the wheelchair must be inspected by an OFFCARR representative before any further use. |
|
|
No alterations or substitutions can be made to the wheelchair securement points or to structural and frame parts or components without consulting OFFCARR. |
|
|
When applying the occupant restraint, make sure to position the seatbelt buckle so that the release button is not in contact with the wheelchair components during transport or in case of a crash. |
7.1. Vehicle attachment points
7.1.1. Attachment of the wheelchair for use within a motor vehicle: QUASAR GT
|
Quasar GT is provided with four (4) attachment points A for a standard 4-point floor tiedown system, as indicated in the figure. When connecting the wheelchair to a vehicle, connect the attachment system to the four marked connection points. These are the most solid points of contact on the wheelchair, and the only connection points certified by the crash test. |
7.1.2. QUASAR GT vehicle attachment points
|
Quasar GT is provided with four (4) attachment points A for a standard 4-point floor tiedown system, as indicated in the figure. When connecting the wheelchair to a vehicle, connect the attachment system to the four marked connection points. These are the most solid points of contact on the wheelchair, and the only connection points certified by the crash test. |
8. 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 8.2, “Replacing front wheels”).
-
✓ Check the efficiency of the bearings. Replace any stuck bearings if necessary (see 8.3, “Replacing rear wheel bearings”, 8.4, “Replacing front wheel bearings” and 8.5, “Replacing front fork 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.
|
|
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. |

8.6. Quick extraction devices
8.6.1. Check
The quick extraction axles are shipped already checked and adjusted. However, it is recommended to periodically verify the effectiveness of their operation.
|
|
8.6.2. 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. |
|
-
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. |
9. Cleaning and disinfection instructions
|
|
Cleaning and disinfection procedure have to be performed exclusively by qualified personnel. |
|
|
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. |

15. 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.
|
|
Please refer to authorized and qualified personnel to perform the adjustments described in this manual. |
15.1. Seat depth adjustment
15.2. 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. |
Adjustable axle QUASAR – IDRA allow adjusting the centre of gravity (COG). To change the centre of gravity:
|
|
|
|
The adjustments must always be made symmetrically. |
|
|
Once the position of the rear wheels has been changed, it is essential to adjust the position of the parking brakes (see 15.8, “Brakes adjustment”) and, if necessary, the position of the side-guards (see 15.6, “Side-guard adjustment”). |
15.3. Rear seat height adjustment
|
|
Be careful not to change the front seat height while replacing the front wheels. |
15.4. Front seat height adjustment
15.5. 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.
|
|
|
|
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. |
|
|
The adjustment must be carried out symmetrically on both forks. It is important to check the symmetry carefully after each adjustment. |
15.6. 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.
15.6.1. EOS, EOS3, QUASAR
15.7. Rear wheels camber adjustment
|
|
15.7.1. Adjusting for Non-0° Camber.
15.8. 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:
CLASSIC BRAKES (pull or push)
|
|
COMPOSITE AND SCISSOR BRAKES
|
|
15.9. 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.
|
|
15.10. Footplate tilt adjustment
15.10.1. Single aluminium profile footplate
If the wheelchair is fitted with an aluminium profile single footplate, the orientation of the footplate can be adjusted as follows:
|
|
15.10.2. Separate aluminium footplates
If the wheelchair is fitted with separate aluminium profile footplates, the orientation of the footplates can be adjusted as follows:
|
|
15.10.3. Plastic footplates
If the wheelchair is fitted with plastic footplates, the orientation of the footplates can be adjusted as follows:
|
|
15.11. Backrest tilt adjustment
Fixed side-guards
The backrest tilt angle and side-guards position are linked and adjustable as follows:
|
|
Once selected the backrest tilt, the position of the carbon fibre side-guard has to be adjusted:
-
adjust the side-guards position, making sure that the distance between the side-guards and the wheels stay around 6mm
-
fix the A and B screws firmly
Removable side-guards (not for ZODIAC)
|
|
The backrest angle (relative to ground) is linked to the seat angle (relative to ground), take note of the seat type (Straight/Ergo), seat depth (DP) and difference of seat height values (Front height (HA), Rear height (HP)) to choose the correct position. |
The backrest tilt angle and side-guards position are independently adjustable as follows:
|
|
|
Insert positioning for standard frames |
|
Insert positioning for Ergo frames |
Once selected the backrest tilt, the position of the carbon fibre side-guard has to be adjusted:
|
|
15.12. 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.
|
|
-
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. |
15.13. Backrest tension adjustment
The backrest tension can be easily adjusted by acting on the velcro straps:
|
|
15.14. Height adjustable pushing handles adjustment
If the wheelchair is equipped with height adjustable pushing handles it is possible to adjust them:
|
|
|
|
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. |
15.15. Adjustment of the anti-tip device
The activation height of the anti-tip device is defined during assembly. However, if necessary, it is possible to modify its distance from the ground and/or change the position of the end piece, thus varying the activation threshold.

-
Loosen the screws A on the support bar without removing them
-
Assemble the support bar by inserting the lateral ends into the guides of the brackets H, paying attention to the knobs M, and fix the screws A to lock the width
-
Insert the sliding support of the abductor into its guide and secure it with the wing screw N.
To adjust the depth of the abductor, or remove it to facilitate transfers or other manoeuvres of the user in the wheelchair, act as follows:
-
Loosen the wing screw N
-
Position the dock to the desired depth and tighten the wing screw N or completely remove the abductor knob from the seat.
In this case of only removing the abductor knob, the support bar remains mounted on the wheelchair and does not allow it to be closed for transport.
To fold the wheelchair it is essential to remove the abductor knob with the support bar:
-
Pull one of the two knobs M to release the support bar;
-
Remove the support bar by pulling it out of its slots in an arching motion.
The bar can be removed with or without the knob inserted. With the user sitting in the wheelchair, it is recommended to remove the abductor knob separately and then the support bar if necessary.
