Safety

Safety information
This section contains important safety information for the protection of the wheelchair user and assistant and safe, trouble-free use of the wheelchair.

WARNING! Risk of Serious Injury or Damage

  • Improper use of this product may cause injury or damage.
  • If you are unable to understand the warnings, cautions or instructions, contact a healthcare professional or provider before attempting to use this equipment.
  • Do not use this product or any available optional equipment without first completely reading and understanding these instructions and any additional instructional material such as a user manual, service manual or instruction sheet supplied with this product or optional equipment.

WARNING! Risk of death or serious injury

  • In case of fire or smoke, wheelchair occupants are at particular risk of death or serious injury, when they are not able to move away from the source of fire or smoke. Lighted matches, lighters and cigarettes can cause an open flame in the wheelchair surroundings or on clothes.
  • Avoid using or storing the wheelchair near open flames or combustible products.
  • Do not smoke while using the wheelchair.

WARNING!

  • Risk of accidents and serious injury
  • Accidents with resulting serious injury can occur if the wheelchair is improperly adjusted.
  • Contact your wheelchair provider with a qualified technician to do the adjustments needed.

WARNING! Risk of overturning

  • The longitudinal position of the rear wheel axis compared to the backrest position affects the wheelchair stability.
  • Moving the rear wheel axis frontwards makes the wheelchair less stable, increasing the risk of tipping backwards. But it improves the manoeuvrability with a better grip position of the handrim and a short turning radius.
  • Moving the rear wheel axis backwards makes the wheelchair more stable, and it will tilt less easily. But it reduces the manoeuvrability.
  • Depending on your particular abilities and safety limits, you can install an anti-tipper device to compensate the decrease of stability.

WARNING! Risk of tilting

  • The rear wheel axle position and the angle of your wheelchair’s backrest are two of the key adjustments that can affect your stability.
  • The changes of rear/front wheel position and/or angle fork adjustments must only be performed by a qualified technician after the assessment of your healthcare professional.

WARNING!

  • Risk due to driving style being unsuitable for the environmental conditions.
  • There is a risk of skidding on wet ground, gravel or uneven terrain.
  • Always adjust your speed and driving style to the conditions (weather, surface, individual ability, etc.).

WARNING! Risk of injury

  • In a collision, you could sustain injury to parts of your body that extend beyond the wheelchair (e.g. feet or hands).
  • Avoid an unbraked collision.
  • Never drive into an object head-on.
  • Drive carefully through narrow passages.

WARNING! Risk due to wheelchair being out of control

  • At high speed, you could lose control of your wheelchair and overturn.
  • Always adjust your driving speed to the given conditions.
  • Avoid collisions in general.

WARNING! Risk of accidents

  • Safety devices that are incorrectly set or no longer working (brakes, anti-tipper) can cause accidents.
  • Always check that the safety devices are working before you use the wheelchair and have them regularly checked by a qualified technician or your provider.

CAUTION! Risk of Injuries

  • In case of pressure sore or injured skin, protect your injured to avoid direct contact with the fabrics of the device. Refer to a healthcare professional for medical advice.

CAUTION! Risk of injuries

  • The use of a manual wheelchair can lead to shoulder pain. The following recommendations reduce this effect:
  • Move the rear wheels further forward so that the arms can move within the anatomical range.
  • Make sure that the sits in an ergonomically seat position as the disability allows.

CAUTION! Risk of burning

  • The wheelchair components can heat up when exposed to external sources of heat.
  • Do not expose the wheelchair to strong sunlight before use.
  • Before usage, check all components that come into contact with your skin for their temperature.

CAUTION! Risk of getting fingers caught

  • There is always a risk of getting, e.g. fingers or arms, caught in the moving parts of the wheelchair.
  • Make sure when activating the folding or insertion mechanisms of moving parts, such as the removable axle of the rear wheel, folding backrest or antitipper, that nothing becomes caught.

CAUTION! Risk of tipping

  • The hanging of additional load (backpack or similar items) onto your chair’s back posts can affect the rearward stability of your wheelchair.
  • Invacare strongly recommends the use of an anti-tipper (available as an option) when using your back posts with the additional load.

CAUTION! Risk of Injury

  • Non-original or wrong parts may affect the function and safety of the product.
  • Only use original parts for the product in use.
  • Due to regional differences, refer to your local Invacare catalogue or website for available options or contact your Invacare distributor. See addresses at the end of this document.
  • NOTICE! When combining this product with another product, the restrictions of both products apply for the combination. E.g. the maximum user weight of one product in the combination may be lower.
  • Only use combinations allowed by Invacare. Contact your Invacare distributor for information.
  • Before use, read the user manual of each product and check the restrictions. Full compliance with the information, instructions and recommendations contained in both user manuals is necessary for a safe use.
  • NOTICE! Risk when using an add-on to support or substitute propelling the wheelchair
  • For safety reasons, it must only be operated by persons who have the physical and mental ability to safely operate the wheelchair with the add-on attached to it in all possible situations (e.g. road traffic) and, in the event of the add-on failing to work or shutting down, can brake the wheelchair and stop safely.
  • Any use contrary to the intended use involves a risk of injury.
  • At high speed, you could lose control of your wheelchair and overturn.
  • Drive carefully.
  • Always adapt your speed and your driving style to the conditions (weather, surface, individual ability, etc.).
  • Avoid collision.
  • An add-on to support or to substitute propelling the wheelchair increases the strain on the wheelchair structure.
  • After each use of an add-on, check the wheelchair for frame cracks or loose screwing.
  • If any sign of fatigue on the wheelchair structure, stop using the wheelchair immediately and contact a qualified technician.

  • Make sure that both castors are facing straight to the front.

WARNING! Risk of overturning

  • The wheelchair could tip forward if you stand on the footrest.
  • Never stand on the footrest when getting in and out.

CAUTION!

  • If you release or damage the brakes the wheelchair could roll away out of control.
  • Do not put yourself on the brakes when getting in and out.

NOTICE!

  • The mudguards and armrests could become damaged.
  • Never sit on the mudguards or armrests when getting in and out.
  1. Propel the wheelchair as near as possible to the seat that you want to move to.
  2. Apply the parking brakes.
  3. Remove the armrests or move them upwards out of the way.
  4. Place your feet on the ground.
  5. Hold the wheelchair and, if necessary, also hold a fixed object in the vicinity.
  6. Move slowly to the chair.

Driving and Steering the Wheelchair

  • You drive and steer the wheelchair using your hands. Before driving without an assistant you must find your wheelchair’s tipping point.

WARNING! Risk of Tipping

  • The wheelchair can tip backwards.
  • When finding the tipping point, an assistant must stand immediately behind the wheelchair to catch it if it tips over.
  • To prevent tipping, install an anti tipper device.

WARNING! Risk of Tipping

  • The wheelchair can tip forward.
  • When setting up your wheelchair, test its behaviour in terms of tipping forward and adjust your driving style accordingly.

CAUTION!

  • A heavy load hanging on the backrest can affect the wheelchair’s centre of gravity.
  • Change your driving style accordingly.

Finding the Tipping Point

  1. Release the brake.
  2. Roll backwards a short distance, grasp both handrims firmly and push forwards with a slight kick.
  3. The shift in weight and steering in opposite directions with the handrims will enable you to identify the tipping point.

Negotiating steps and kerbs

WARNING! Risk of overturning

  • When negotiating steps you could lose your balance and tip the wheelchair over.
  • Always approach steps and kerbs slowly and carefully.
  • Do not go up or down steps that are higher than 25 cm.

CAUTION!

  • An activated anti-tipper prevents the wheelchair from tipping backwards.
  • Deactivate the anti-tipper before going up or down steps or kerbs.

WARNING!  Risk of injury to the assistant and damage to the wheelchair

  • Tilting the chair with a heavy user can hurt the assistant’s back and damage the chair.
  • Make sure to be able to safely control the wheelchair with a heavy user before performing a tilting maneuver.

Going down a step with an assistant

  1. Move the wheelchair right up to the kerb and hold the handrims.
  2. The assistant should hold both push handles, place one foot on the tipper aid (if installed) and tilt the wheelchair backwards so that the front wheels lift off  the ground
  3. The assistant should then hold the wheelchair in this position, push it carefully down the step and then tilt it forward until the front wheels are back on the ground.

Going up a step with an assistant

WARNING! Risk of serious injuries

  • Going up steps and kerbs more often than normal use can cause a fatigue break of the wheelchair backrest and the user might fall out of the wheelchair.
  • Make sure that the wheelchair can be controlled by the user or the assistant before performing a tilting maneuver.
  • Move the wheelchair backwards until the rear wheels touch the kerb.
  • The assistant should tilt the wheelchair using both push handles so that the front wheels lift off the ground, then pull the rear wheels over the curb until the front wheels can be placed back on the ground.

Going down a step without an assistant

WARNING! Risk of tipping

  • When going down a step without an assistant you could tip over if you cannot control your wheelchair.
  • First learn how to go down a step with an assistant.
  • Learn how finding the tipping point to balance on the rear wheels,6.4 Driving and Steering the Wheelchair, page 25.
  1. Move the wheelchair right to the kerb, lift the front wheels and keep the wheelchair balanced.
  2. Now slowly roll both rear wheels over the kerb. While doing this, hold the handrims firmly with both hands until the front wheels are back on the ground.

Going up and down stairs

WARNING! Risk of overturning

  • When negotiating stairs you could lose your balance and overturn your wheelchair.
  • Always use two assistants when negotiating stairs with more than one step.
  1. You can go up and down stairs by taking them one step at a time, as described above.
  2. The first assistant should stand behind the wheelchair holding the push handles.
  3. The second assistant should hold a solid part of the front frame to steady the wheelchair from the front

Negotiating ramps and slopes

WARNING! Risk due to wheelchair being out of control

  • When negotiating slopes or gradients your wheelchair could tip backwards, forwards or sideways.
  • Always have an assistant behind the wheelchair when approaching long slopes.
  • Avoid lateral slopes.
  • Avoid slopes of more than 7°.
  • Avoid jerking when changing direction on a slope.

CAUTION!

  • Your wheelchair could run away even on slightly sloping ground if you do not control it using your handrims.
  • Use the parking brakes if your wheelchair is stationary on sloping ground.

Going up slopes

  • To go up a slope, you must create some momentum, keep up the momentum and control the direction at the same time.
  • Bend your upper body forward and propel the wheelchair with quick, powerful strokes on both handrims.

Going down slopes

  • When going down slopes, it is important to control your direction and particularly your speed.
  • Lean back and carefully allow the handrims to run through your hands. You should be able to stop the wheelchair at any time by gripping the handrims.

CAUTION!

  • Risk of burning your hands.
  • If you brake for a long time, a lot of frictional heat is produced in the handrims.
  • Wear suitable gloves.
