2. Using the device

In order to move safely and properly use the device, it is always recommended to consult qualified personnel.

Hereafter are some suggestions for a correct use of the device, also aimed to maintain the characteristics of safety and durability over time:

The brakes only have a parking purpose and should never be used as service brakes to slow down the device in motion.
Do not lean too far forward, because by moving the centre of gravity, the device could tip-over.
The device should be used only in accordance with what is proposed in this manual and not of objects in general.
Always deal with slopes above 6° with assistance from an attendant. This limit is only approximate and it depends on the specific configuration of the device, especially on the position of the centre of gravity of the user-wheelchair combination.
To ensure the efficiency of the brakes, maintain the tyres properly inflated and quarterly check the knurled locking pin wear.
Never use the anti-tip devices, if available, as transit wheels.
The armrests, if available, are not designed to lift the device.
Avoid wheeling the device without the supervision of an attendant.
Perform a general check of the device at least every three months, by checking tyre inflation, efficiency of the quick-release axles and brakes; lubricate the moving parts whenever necessary.
If necessary, the upholstery can be washed with water at low temperature. Avoid wetting or submerging other parts of the device.
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 security features of the materials involved.
Avoid contact with seawater and sand. In case of contact proceed to an immediate and accurate cleaning.
Clean periodically the device using a damp cloth and avoid even partial immersion of the frame. Keeping the device clean enhances its efficiency.

Suspend the use of the product and notify OFFCARR in case of allergic reactions or if other similar problems are developed after contact with the device materials.

There is no apparent danger of causing injury to people during the operations of preparation and setup of the device if carried out according to the instructions provided in this manual.

Make sure the tyres are correctly inflated. Since the correct pressure differs between models, read the required pressure on the side of the tyre itself.

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. 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.

5.2. 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.

5.3. 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.

5.4. 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

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

6.1. 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 5.1, “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

Deflate the wheel
Insert a special lever between the rim and the shoulder of the tyre so that when the lever is overturned, the side of the tyre comes out (fig. 1 and 2).

Tyre/tube disassembly 1

Tyre/tube disassembly 2

Insert another lever 100mm away from the previous point and repeat the operation (fig.3).
Slide the two levers along the circle to free the entire shoulder of the tyre.

Tyre/tube disassembly 3

Extract the inner tube, starting from the side opposite the inflation valve (fig. 4).
Once the inner tube has been extracted, it is easy to remove the tyre to replace one or both of them.

Tyre/tube disassembly 4

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.
