Battery Care & Storage

Charge battery after every ride. It is not necessary to fully discharge battery before charging. Lithium batteries do not have any memory effect, so you can charge them at any time. Lithium batteries must not be stored if fully discharged. If your battery is fully discharged, charge it as soon as possible. Storing the battery if fully discharged for longer than 1 day will damage the battery. It is recommend to store the batteries fully charged and then charge it at least every two months. It is not necessary to leave the charger connected to the battery if stored for long periods. Just top the charge up every two months. Disconnect charger from battery and power supply after battery has been fully charged. If batteries are not charged at least every two months, the battery may be damaged and such damage is unfortunately not covered under manufacturer’s fault warranty.
WARNING! Lithium-ion batteries may leak, ignite and burst if not handled properly! Always keep away from any material which can catch fire.
Store battery between 10 ℃ (50 °F ) and 30℃ (86 °F) in a clean, dry place away from sunlight. Do not store with hazardous, corrosive or flammable materials. Do not expose batteries to heat or fire. Store batteries in fire-proof environment. Operating temperature range during discharge is 5℃ (41 °F ) to 50℃ (122 °F). Do not leave the battery inside car, in direct sunlight or any other hot places. If battery is charged at temperatures lower than 5 ℃
(41 °F ), the range of battery will be reduced.
Do not disassemble, deform or modify battery. Do not connect the + and – terminals of battery with metallic or conductive objects. Do not store with conductive objects such as hairpins or necklaces as short circuits and burns may occur. Do not short circuit battery. Only use original charger.
Do not place into water, salt water and moisture. Do not throw battery or subject it to strong shocks.
Inspect battery and terminals carefully every month for leakage, discoloration, cracks, damage, bloating, signs of melting or corrosion. If fluid leaks from the battery and gets into contact with your eyes or skin, wash affected area with clean water without rubbing your eyes or skin and visit a doctor immediately to reduce damage to eyes or skin. Never handle battery or charger if parts are wet. Dry it thoroughly before usage to avoid electric shock. Store out of reach of pets and children. Battery capacity naturally declines over time and is warranted to be at least 80% capacity within 1 year of purchase.
Always handle carefully with 2 hands. If errors occur, stop using battery, consult manual or contact customer service. Discard batteries according to your local battery disposal guidelines.

Safety warnings

After releasing the brakes, the wheelchair can be pushed manually and it can’t be operated by the occupant anymore.
Before releasing the brakes, double-check that the folding safety clamp at the back of the wheelchair is locked. If the safety clamp is not locked, the wheelchair may fold while the occupant is on the wheelchair.
Make sure the grip of the bar on top of the backrest is stable and suitable for pushing the wheelchair manually. Make sure that the backrest is installed safely. Only release brakes with the consent of occupant. Only release brakes on flat and even surfaces. Do not release brakes on inclines or declines. Pushing the wheelchair manually may be harder as compared to pushing a non- motorized wheelchair due to drag of the motors in the rear wheels.

Folding the wheelchair

Before folding the wheelchair, remove the seat cushion (C). It is attached to the wheelchair by Velcro and can be removed by simply lifting it up (direction of arrow). Fold the chair slowly and carefully. Make sure the batteries will not fall out accidentally during folding. Caution! Pinching hazard. Take care not to injure yourself while folding the chair.

Releasing and closing the folding safety lock

• The folding safety lock is located at the centre of the backside of the wheelchair (red circle). Warning! It needs to be locked if the wheelchair is occupied. The lock holds the wheelchair together and prevents it from folding .
• To fold the wheelchair, unlock the safety lock by pushing the top part of the black lever. The lever will disengage from the lower silver bolt. Now the wheelchair can be folded. Warning: Do not occupy the wheelchair if the clamp is released!
• To lock the wheelchair folding mechanism, make sure that the lower part of the black lever holds the lower silver bolt. Check that the wheelchair is locked, stable and safe before occupying.
• After unlocking the folding safety lock, grab the wheelchair by the top of the backrest and at the centre of the front frame of the seat and fold it in the direction of the arrows. Leave the weight on the rear wheels. (Please note this illustration shows the wheelchair with the seat cushion. Please remove the seat cushion before folding as it may be in the way).
• Fold the wheelchair as shown above. Fold the wheelchair slowly and avoid over-stretching any wires. If necessary adjust wires to release tension. Remove joystick (circle) if you wish to reduce the size further (refer to instructions elsewhere in this manual).

Installing the seat cushion

• Make sure all 4 Velcro straps under seat cushion are secure (arrows). Make sure the lower part of the back-rest is attached to the Velcro at the back of the seat (red rectangle)
• Attach seat cushion with zip facing the back. Make sure cushion is attached securely. The COVER of the cushion is removable and washable ( up to 80 degrees).

Installing the backrest

View from the front: First make sure that the lower part of the back-rest is attached to the back of the seat (red rectangle). Then, attach front part of backrest padding to the Velcro (arrows).

View from the back: Make sure the two horizontal straps (S) are tight. Attach the back part of the backrest to the upright Velcro lines (V ).

Correctly installed backrest (front view).

Correctly installed backrest (rear view). Make sure the backrest is installed safely before use.

Installing the joystick on right hand side armrest

• Align the joystick console with the opening on the right hand side armrest as shown in the picture above and insert it into the armrest tube (direction of red arrow).
• Turn the knob (K) anti-clockwise until the joystick console is installed safely and won’t move.
• Carefully connect the black plastic pin on the joystick cable with the groove on the cable on the wheelchair armrest. Do not use force! Do not damage the metal pins inside the joystick cable! If they are bent by accident, carefully bend them back with a forceps. Damaging metal pins during installation is not covered by warranty.
• After connecting the wires, move the barrel (arrow) to the centre and turn it in the direction of the arrow. This will lock the two cables in place and prevent them from disconnecting by accident. Adjust the wire slack so that the wire is not in the way while operating the wheelchair.

Installing the joystick on left hand side armrest

The wheelchair is setup by default to have the joystick installed on the right hand side. It is possible to install the joystick on the left hand side armrest. In short, remove the wire, install the wire on the left side and install the console in the same way as on the right side. Please follow the instructions below.

Unscrew the knob (K) by hand from the right armrest and screw it into the same socket on the left armrest. Use a screwdriver to remove the screw (arrow) witch holds the black cable latch

Cable management
The cable of the joystick console runs down the back of the wheelchair and is fastened with cable-ties. Carefully note the position of the cable ties (arrows) and then remove the cable ties carefully with a paper knife or scissors. Attach the wire carefully with new cable ties on the left hand side. Please note that the cable needs slack for folding. It shouldn’t be too tight as it may damage the cable when folding. The cable should also not touch any wheels or the ground. If you need help please contact us or ask your local mobility shop for assistance.

Remove the round black cover (C) on the left armrest and put it on the right armrest. Remove the screw and washer at the back of the left armrest (arrow) and install the cable latch. Insert the joystick console, fasten it securely with the knob and check that both armrests are installed safely with all screws. When folding the wheelchair for the first time, do so slowly and carefully, to make sure the cable is not stretched too much. If it’s stretched, adjust cable tension until the wheelchair can be folded safely.

Removing and installing the batteries

Warning : always switch wheelchair power OFF before removing or installing batteries.

• The batteries are located underneath the seat (red arrows). Grab battery at handle (red arrows) and gently pull battery towards the front of the chair.
• The batteries can only be inserted into the battery tray if they are in the right orientation.
• Make sure the battery is all the way in and stable and won’t fall out. Do not use force.

Charging the batteries

The wheelchair is equipped with quality Lithium batteries. Lithium batteries are a modern technology which is not suffering from memory effects like some older battery types, which means that Lithium batteries can be charged anytime, also e.g. if they were only half discharged. It is recommended to charge the battery after each use. This will not reduce the battery life. Charging an empty battery takes about 7 hours and it will take less time if there is still charge remaining in the battery. Please note the wheelchair may have a lower top speed when the batteries are near empty.

Battery Care & Storage
Lithium batteries must not be stored if fully discharged. If your battery is fully discharged, charge it as soon as possible. Storing the battery if fully discharged will damage the battery. Such damage is not covered by the manufacturer’s fault warranty. It is recommend to store the batteries fully charged and then charge it every two months. It is not necessary to leave the charger connected to the battery if stored for long periods. Just top the charge up every two months.

Warning: always switch wheelchair power OFF before charging batteries .

To charge both batteries on the wheelchair, connect the big round silver 3-prong connector to the inlet on the underside of the joystick console, then connect the charger to the power point (AC 110-220 V, 50-60 Hz).
Warning: the charger may get very hot. Always keep charger away from any materials which can catch fire. The charger is intelligent and will stop charging once the battery is full. Red light on charger: charging. Green light on charger: fully charged (or not connected).

Functions of the joystick console

Using the joystick

Move backwards
Move the joystick in the directions shown above. If the joystick is released, the wheelchair will stop and the brakes will engage. Do not make sharp movements with the joystick. Always control the wheelchair with care. The joystick control is proportional, which means if you push it just a little and wait for two seconds, the wheelchair will move slowly, but if you push it all the way, then the wheelchair will move at the maximum speed set on the console. Start using the joystick at low speed levels and only push it gently. Strap (NOT included with most wheelchairs)

• If your box contains a strap, please refer to warnings below.
  WARNING: Straps can be a choking hazard if used incorrectly. Do not use unless you have consulted a professional first how to use straps on wheelchairs.
  Use the latch (circle) to adjust length (approximately from 82cm to 144cm length). Push both ends together in the directions of the arrows to close the strap.

• To release strap, push in the direction of the arrows and pull both ends apart.
