Product Description

Amasis racing wheelchair

• Amasis is the ultimate bid for maximum transfer of the athlete’s forces. In athletics as well as in long-distance races, Amasis race chair has since 2004 won many victories for the Paralympic physician and beat world records.
• Amasis has a frame in tempered 7020 lightweight aluminum. With its extra-thick frame, the racing wheelchair becomes rigid and robust, thus transferring all the athlete’s forces to energy and propulsion.
• Amasis is tailored to the individual user’s needs and wishes. Wolturnus offers several upgrade options, which will be mentioned in section 7. Accessories and Equipment.

Amasis skiing chair

• The skiing chair is a revamped version of the Amasis race wheelchair. With a higher and more upright seating position, the chair is optimized to be driven with ski poles, for training in the off-season.
• It shares the strong and lightweight 7020 aluminum frame with the Amasis, but with a shorter axle distance, it is more maneuverable for riding in winding terrain.
• The hinged steering unit makes it easy to fold away when getting into the chair.

The following table gives an overview of how to maintain the wheelchair .

In the event of faults or missing parts, contact the supplier or Wolturnus A/S. For contact information, go to section 12. Wolturnus A/S recommends that the wheelchair is serviced at least once a year by the supplier or Wolturnus A/S.

INFORMATION
After storage of the wheelchair for a longer period of time, perform maintenance accordingly.

Cleaning and Disinfection
The wheelchair should be cleaned regularly according to how often it is used and how dirty it is. Clean the frame, plastic parts, and wheels with a mild cleaning agent. After cleaning, dry all parts with a dry cloth. Clean cushions and upholstery with warm water and washing-up liquid. Remove stains with a sponge or a soft brush. Rinse afterward with clean water and allow the parts to dry before mounting and using.

To disinfect, use water-based agents and follow the manufacturer’s instructions.

NOTICE

• The wheelchair must not be used in salt water. Avoid getting salt, sand, and other dirt that can cause damage to the wheel bearings, caster mounting bracket, or rear wheels. If this happens, the bearings should be replaced.
• Do not use corrosive cleaning agents, solvents, or hard brushes.
• Do not wet-wash. Do not use high-pressure equipment or a water jet. The wheelchair com-ponents must not be put in a washing machine.
• Clean the seat and back upholstery, cushions, handles, and armrest before disinfecting.

Changing a Tire
If a tire is punctured, the user or a helper may be able to change it without assistance. The procedure requires having strong hands, practical ability, and suitable tools. It is advisable to have a puncture repair kit and an air pump for emergencies (excluding situations with puncture-proof tires). Suitable air pumps, puncture repair kits, or puncture sprays that fill the tire with expanding foam can be purchased at most bicycle shops.

Removing tires and tubes

• Gently pull the tire edge over the edge of the rim with a tire lever (or two, if it is sitting very tightly). Take care not to damage the rim or the tube (Image 14).
• Screw off the valve nut and pull the valve out from the rim and the rim tape.
• Pull out the tube from between the tire and the rim (Image 15).

Repair and check-ups

• Repair the tube according to the instructions in the repair kit or replace it with a new tube.
• Before remounting the tire and tube, make sure that no foreign objects that may have caused the puncture are caught in the rim or tire.
• Ensure that the rim tape is intact. It protects the tube against damage from the spokes.
• Push the tube into place between the tire and the rim.

Mounting tires

• Gently pull the clear tire edge over the edge of the rim. Starting with the valve.
• Check that there are no twists at all in the tube, otherwise, air can get out.
• Work the whole way around until the last section of the tire edge is taut and can be edged into place with one or two levers.

Pumping tires

• Check on both sides that the tube is not caught between the tire edge and rim.
• Push the valve lightly in and pull It out again to make sure that it is not caught on the tire edge.
• Fill the tire with air to the point where it is still possible to press it in with a thumb. If the control lines on both sides of the tire indicate the same distance to the rim edge, the tire is centered. If the tire is not centered, let some air out and adjust the tire until it is centered. Now pump up the tire to its maximum working pressure (see the side of the tire) or at least 3.5 bars (350 kPa). Then screw the dust cap on, tightly.

CAUTION!
Ensure that the tires have the correct pressure before using the chair. The maximum air pressure limit is marked on the side of the tire. It must always be on a minimum of 3.5 bars (350 kPa) on the rear wheels. Like push wheel locks, knee-lever wheel locks are only effective when the air pressure is sufficiently high and when they are correctly positioned. (When locked, the brake pad should push the tire in 5mm (allowing for technical alterations).

Troubleshooting

During routine maintenance, it may be necessary to make adjustments or repair faults. In most cases, the solution to the problem can be found on the following list:

If the problem cannot be solved with the aid of the troubleshooting section, contact the supplier or Wolturnus A/S. Contact information: section 12.

Instructions for Reuse

The wheelchairs are suitable for reuse by a subsequent new owner. It is essential that the wheelchair´s measurements and equipment are tailored to suit the new user. It follows that it is important to ensure that the wheel- chairs functions and features have not been altered to a degree that could create a safety risk for the new user or any third parties during the lifetime of the chair.

Based on market studies and on its knowledge of contemporary technology, Wolturnus A/S has calculated that the wheelchair, when used, serviced, and maintained in accordance with the original instructions, has a lifetime of 5 years (excluding time kept in storage by an authorised dealership or the user). Note that with careful care and proper use, the wheelchair can be used for a longer period than the defined lifetime.

Prior to reuse, the wheelchair must be carefully cleaned and disinfected. Then the product must be inspected by an authorised specialist to assess its condition, wear and tear, and damage. All worn or damaged parts and components that do not suit or are not designed for the new user must be replaced. This user´s manual includes a service plan (see maintenance chart section 8) and detailed information about the wheelchair.

Disposal
If the wheelchair is delivered in a brown cardboard box, that can be handed into recycling centers or cardboard collection points. The protective bubble wrap on the frame must be disposed of as combustible waste. The aluminum frame must be disposed of as metal. The upholstery and side panels must be disposed of as combustible waste.

Environment
Wolturnus A/S strives to respect the environment as far as possible. An assessment has been done to determine the wheelchair’s effect on the environment during its life cycle. During development, materials and forms are chosen that minimize the waste of energy and material during production.

Wolturnus A/S has a unique approach to individual user measurement and to the subsequent special design of the chair to meet the user’s needs, preferences, and requirements. Combined with the wheelchair’s mechanical quality, this ensures that the user can use the wheelchair for many years. The wheelchair’s lifetime is calculated to be approximately 5 years if maintained according to the instructions in this user´s manual. The long lifetime limits the wheelchair´s effect on the environment.

Furthermore, meticulous quality control throughout the production process ensures that faults are rare, which limits the need to use superfluous resources on repairs or replacement products. Generally, all functions, working processes, and labor at Wolturnus A/S are carried out with respect for the environment. The aluminum residue after the production process is collected in containers and delivered for recycling. During the mounting process, the usage of hazardous agents is kept to a minimum. Furthermore, all work processes meet occupational safety requirements (APV). The usage of all materials is continually optimized to ensure minimum waste.
