5.- Warnings and safety

Failure to follow these safety precautions may result in serious injury.

  • Follow the folding and assembly instructions and ensure that all parts of the chair are securely fastened before use. You should take great care when using and travelling.
  • Avoid leaning your body so much that you overbalance the chair, avoid sudden accelerations and braking, and do not go fast so that the wheelchair remains stable.
  • Slow down when appropriate for the conditions (obstacles, wet surfaces, strong wind, tight spaces, etc.).
  • Care is particularly required when tackling ramps, curbs and changes of level. Ramps must be wide enough for safe passage. Do not go up or down a slope steeper than 12° alone, it could be dangerous. The surface of the slope should be firm and non-slip. You can go up and down curbs with the help of someone else.
  • Stairs are an insurmountable and very dangerous obstacle for wheelchair users. If there are no alternative routes to the stairs, such as ramps, lifts or platform lifts, navigate the stairs with the help of one or more other people. They should hold the chair by its fixed, non-detachable parts.
  • The minimum dimensions for wheelchair use of lifts are:
  • Usable depth > 1200 mm - Usable width > 900 mm - Clearance between doors > 800 mm - Surface area > 1.5 m²
  • Uneven surfaces such as broken road surfaces, gravel, grass, sand, mud or decking are difficult to navigate in a wheelchair and can even cause falls.
  • For safety during any transfer, apply the parking brakes.
  • Do not hang anything on the back of the chair or on the handles, which could cause the chair to tip over.
  • After making any adjustment to the chair, we recommend checking all the screws of the chair. It is reasonable to expect that just from everyday use, the screws and nuts may come loose. If they have done, contact your dealer.
  • The brakes are intended for use as parking brakes and not to slow down or stop the chair in motion. Forta accepts no liability for the consequences of any improper use.
  • All detachable components must be assembled with care to avoid injury or damage to the wheelchair.
  • Make sure that the wheelchair is fully unfolded and that the detachable components are fixed in place and correctly positioned before use.
  • To go up or down steps, pavements, etc., the wheelchair must be fully open and the feet on the right rests.
  • The wheelchair is not suitable for use as a seat in a motor vehicle.
  • In the case of wheelchairs with pneumatic tyres, you should regularly check the pressure in the tyres. We recommend checking every week.
  • Make sure all parts are securely fastened and in good working order before using the wheelchair.
  • Replace any wheelchair components that are worn or damaged.
  • Test the parking brakes on the wheels before using the wheelchair. When the wheels are locked the brake shoe should stop the wheels turning.
  • When the parking brakes are released the wheels should be able to turn freely
  • Only use accessories and parts supplied by Forta.
  • Do not adjust the wheelchair while it is in use.
  • Do not use the wheelchair on wet, icy or snowy inclines.
  • Keep the wheelchair clean and in perfect condition.
  • All wheelchairs contain or may contain plastic parts that can produce toxic gases if burned. Do not expose the wheelchair or any of its components to intense heat that could make it or them catch fire.
  • Pool water, sand and sea water contain chlorine and other chemicals that will damage the wheelchair, internal bearings and fixings. If the wheelchair is exposed to any of those hazards, vulnerable components should be lubricated with oil and vaseline (spray) and the wheelchair should be washed.
  • We recommend regular checks of the tightness of screws because they may come loose in everyday use.
6.- Assembly and use

Assembly and folding

The wheelchair does not need to be assembled before use except for the footrests, which are shipped unattached to the wheelchair. No tools are required for the assembly of the footrests and armrests.

To place the footrests, follow these steps:

  1. Position the footrest in its place on the chassis, with the plate facing the outside of the chair, and then insert both footrest plates into their corresponding axes on the chair.
  2. Rotate the footrest, bringing the plate to its normal use position. At that moment, the lever will click, and the footrest will be fixed.

To adjust the height, unscrew the plate from the tube, place it at the desired height in one of the 5 different settings, and screw it back in to fix the height.

To remove the footrests, follow these steps:

  1. Pull the footrest lever, pushing it outwards from the chair, until the plate is on the outside of it.
  2. Pull up on the footrest to remove it.

Placement and removal of the armrests:

  • To place the armrests, just position them over their guides and snap them gently downwards.
  • To remove the armrests, proceed in the reverse manner, acting on the unlocking lever before pulling upwards.

To fold and unfold the chair, follow these instructions:

  • To fold the chair, pull the seat fabric or the tubes it rests on upwards.
  • To unfold it, lower the seat tubes until they fit into their respective guides.

User adaptation

Users of lightweight manual chairs should consider three very important things when choosing a chair.

First, the height and weight of the intended user, i.e. a wheelchair must always fit its user. Second, be clear what you are going to do in the wheelchair (transfers, folding, etc.). Finally, what is the environment in which the wheelchair is going to be used like.

The table makes recommendations that should be taken into account when choosing a wheelchair to meet the needs of a particular user:

Arm length Push rim reach Angle between arm and forearm 120° when holding the push rim
Head-to-floor height Sight distance
Height elbows-floor Armrests height 20mm above elbow with arms extended
Knee height Footrest-to-seat distance Footrest height 100-130mm
Distance buttock-back of knee Distance footrest-seat Seat Clearance of 25mm between thighs and side of armrest
Leg length Seat depth 30-50mm between the seat and the back of the knee
Hip width Seat width Clearance of 25mm between thighs and side of arm rest
Knee angle Seat and footrest tilt Seat tilt 1-4° backwards
Distance armpit-outside of hip Backrest height Backrest 25 mm below the shoulder blade
Approximate weight Wheelchair resistance Maximum user weight of 140 kg

Using the wheelchair

This section provides basic recommendations for use of the wheelchair by the person using it and any companion:

  • Before using the wheelchair, check that it is correctly positioned and that all parts are unfolded and securely fastened.
  • To reach towards and pick up any object, point the front casters towards the object. Before moving your body to reach an object, apply the parking brakes to make the wheelchair stable.
  • The wheelchair must be driven or propelled safely and efficiently. The seat must be set at a height that allows the user to grip the push rim with an angle between the arm and the forearm of about 120º. The backrest should be tilted slightly backwards.
  • It is important to maintain a steady pace to reduce fatigue as much as possible. If you want to go faster, you should make each push shorter and push with greater frequency, bearing in mind that short pushes increase stability and long strokes give more impetus.
  • We recommend slowing down by holding the push rims and slowing down gradually until the wheelchair comes to a stop. The parking brakes should not be used for braking while moving. It could be dangerous.
  • To turn, grip the push rim with one hand and push it backwards, and push the other rim forwards with the other hand. The further each hand moves, the sharper the turn.
  • The unoccupied wheelchair can be transported by vehicles and by air.

Use of the attendant brakes option

The attendant brakes allow the wheelchair to be stopped safely and conveniently by a companion.
Warning: Brakes should only be installed by operatives authorised by Forta.
Press the trigger on each of the wheelchair’s handles to operate the brakes. To lock the brakes and leave them on, push the red component on the front of the lever.

8.- Care and maintenance

If the product is not cared for and maintained in perfect condition, there will be a risk of accident.

Regular preventive maintenance allows you to keep your wheelchair in optimal working condition and to detect and solve small problems that could develop into major failures over time. Not only does it improve day-to-day safety, but it also saves time and money in the long run.
Note: In the event of a breakdown, any repair should be carried out by a specialist provider (orthopaedics).

General recommendations
Some of the most frequent maintenance and care for your wheelchair are described below:

  • Keeping the wheelchair clean and in perfect condition will enhance its performance and appearance.
  • We recommend using bicycle cleaning and maintenance products like lubricating oils, spray cans, damp cloths, etc.
  • If the chair has been exposed to water from rain, shower, etc., we recommend drying it with a cloth. Spray some bicycle oil on a cloth and apply it to the joints and axles.
  • To wash the fabrics, use neutral soap at a maximum temperature of 30ºC. Do not iron or spin-dry.
  • Check the crosshead union nut, if it is loose, tighten with wrench or spanner.
