Bischoff Bischoff Taiga Robust Outdoor Drive Instruction Manual

Instruction manual

Enjoy mobility.

Introduction

Dear user,
You have decided on a high-quality Bischoff & Bischoff electric wheelchair, and we would like to thank you for your trust.
The electric wheelchair was designed to offer you many advantages and meet your needs. The wheelchair can be fitted to your individual body size thanks to a multitude of adjustable features and optimal adaptability such as the length of the lower leg, the recline of the backrest, the sag of the backrest as well as the swing away function of the control unit and the choice of mounting the control unit either to the left or the right side.
The Taiga can be supplied with two different control systems. In the standard configuration, the Taiga is delivered with the VR-2 controller, which offers you the option of adjusting up to two components electronically. The R-Net controller permits electrical adjustment of the leg rests and the seat and back angles, or when more than two electrical options are needed. Thus, the Taiga can easily be customised to your specific needs.
The electric wheelchair is designed for indoor and outdoor use. Before using your new electric wheelchair for the first time, please read and follow the instructions in this manual carefully. The instruction manual is an integral and necessary part of the  heelchair. This is why you should keep it close by and include it when passing on the wheelchair to someone else. For visually impaired users, this document is available as a PDF file at our website www .bischoff-bischoff.com. Any repairs and adjustments require special technical training and may therefore only be carried out by authorized Bischoff & Bischoff dealers.

Important! This is especially useful information on a given subject.
Warning! These are especially safety-relevant instructions.
Follow the directions in the manual!
2. Important safety instructions
2.1. General safety instructions

• To avoid falls and dangerous situations, you should first practice driving your new wheelchair on level, unobstructed ground. We recommend having an assistant with you.
• Please make sure that all parts have been properly installed before using the wheelchair.
• Practice driving on level, unobstructed ground before first use. Get a good understanding for the way the wheelchair brakes and accelerates when driving straight ahead or a curve.
• Please note that displacing the center of gravity by shifting the body or by adding loads may increase the risk of tipping over the wheelchair to the side or backwards.
• The wheelchair may not be used for transport of more than one person or any additioonal load. Make sure to only use it for the intended purpose.
• Never use the wheelchair under the influence of alcohol or other substances that may impair your attention and/or your physical and mental capacity.
• Please make sure to always use ramps to overcome obstacles.
• Avoid hitting obstacles (steps, curbs) at full speed.
• Please pay attention to the tilt prevention feature on steps, lifting platforms and ramps. Make sure there is enough clearance on top, on the bottom and on the sides.
• The control unit must always be switched off when getting in or out of the wheelchair.
• All road traffic regulations must be observed when driving on public roads.
• The rear lights at the wheelchair must always be visible to other road users.
• If possible, wear bright, conspicuous clothing. This will make it easier for other road users to see you.
• Please note that the upholstery will heat up if directly exposed to sunlight and may cause injuries to your skin when touched. You should therefore cover these parts or protect the wheelchair from exposure to direct sunlight.
• Please note there is a risk of entrapment between moving parts when adjusting, using and maintaining the wheelchair.
• Please note the increased risk to the user, passenger and third parties of getting trapped when using the electric seat adjustment.
• Always place the seat and back rest in an upright position when driving the wheelchair.
• Driving on inclines is only permitted if the seat and back rest are in an upright position.
• At low ambient temperatures, the metal parts of the wheelchair may cool significantly; avoid skin contact in this case.
• If you notice unusual behaviour or damage to your electric wheelchair, discontinue use and contact your specialist dealer.
• Reporting incidents. The operator or user must immediately report
  1. any malfunction
  2. any change to the features or performance as well as
  3. any inaccuracies in the marking or operating instructions of a medical device, which has or could have led to death or to a serious deterioration of the health of a patient, an employee or a third party, to the Federal Institute for Drugs and Medical
  Devices (BfArM). This institute will immediately forward the notification to the operator’s competent authority and also inform the manufacturer and the manufacturer’s competent authority.

2.2. Advice regarding EMC interference
Despite meeting all applicable EMC guidelines and standards it is possible that the wheelchair will experience interference from other electrical devices (e.g. cell phones) or interfere with these. Should you notice such interference, either turn off the other device or your electric wheelchair and move it outside the interference range.
2.3. Brakes
After letting go of the joy-stick the electromagnetic brakes will slow down the wheelchair atuomatically until it comes to a complete stop. The engaged drives serve as a locking brake for the wheelchair. In pushing mode, two mechanical locking brakes are available when the drives are disengaged.
2.4. Use on public roads
The wheelchair is designed for indoor and outdoor use. Please keep in mind that you are using public roads and therefore have to observe all road traffic regulations. Do not endanger other road users through inconsiderate driving, especially on walkways.

Driving functions
Your dealer can adjust the values for speed, acceleration and deceleration to your requirements subject to the legal regulations.
For a start select a low mode and increase it while moving if required.
Use the joystick to start moving. The joystick is used simultaneously to increase the speed and to change the direction of movement. When the joystick is in central position the electro-magnetical brake is active, unless the joystick is not moved the wheelchair stands still.
Moving forward: to move forward in a straight line move the joystick cautiously forward. The further forward the joystick is moved, the faster your wheelchair gets. If you release the joystick the wheelchair will automatically be braked to a stop.
Reversing: to move in reverse mode, move the joystick cautiously back.
The further back the joystick is moved, the faster your wheelchair gets.
If you release the joystick the wheelchair will automatically be braked to a stop.
Turning corners: To change direction of travel, tilt the joystick to the left or right. This can also be done when the joystick is tilted forwards or backwards, i.e. while driving backwards or forwards.
Caution! Driving on inclines is only permitted if the seat and back rest are in an upright position.
Caution! Always place the seat and back rest in an upright position when driving the wheelchair.
4.6. Pushing the wheelchair
If you wish to push the wheelchair in some situations, the brakes must be unlocked. The wheelchair is easy to push in freewheel mode.
Caution! The electromagnetic brake is disabled in this mode.

• With the yellow rotary switch the actuators can be unlocked and also coupled again (fig. 36).
• To be able to push the electric wheelchair manually, turn the switch downwards. The switch will be automatically engage.
• Repeat this procedure with the other actuator. Now you can use the wheelchair in push mode.
• To engage the actuators turn the lever upwards, it will click into place automatically. Also repeat this procedure on the other side.
• A slight jerk tells you that the drive mechanism is now engaged and you can use the driving function.

** Please note that operating the wheelchair in push mode by uncoupling the drive mechanism will deactivate the electro-magnetic brakes. The wheelchair should therefore only be used on level ground in this mode. Non-observance may lead to life-threatening situations.
Caution! Always use both drives in the same position (accident hazard).
Caution!** Danger of fatal injury! The drives must only be unlocked on level ground.

4.7. Leg supports
To make it as easy as possible to enter and leave your wheelchair, the foot plates can be folded up, or the leg rests can be swung to the side out of the way or removed.

• Open the lock to swing the leg rest to the side (fig. 37).
• The leg rest in the swung-out position can be completely removed (fig. 38).
• For electrically adjustable leg rests, the connection cables under the seat must initially be disconnected (fig. 39).
• When you want to replace the leg rest, proceed in reverse order.
• Move the leg rest to the forward position until you hear it lock into place.

4.8. Head rest (optional)
The wheelchair can be equipped with an optional head rest. The settings for the version with the comfort seat are described below; the settings of the standard version are analogous.![Bischoff Bischoff Taiga Robust Outdoor Drive

• Head rest 1](https://manuals.plus/wp-content/uploads/2023/07/Bischoff- Bischoff-Taiga-Robust-Outdoor-Drive-Head-rest-1.png)

  • You can easily adapt the height of the head rest by pulling out the push button (fig. 40) and moving the head rest to the desired height. The push button latches in automatically and audibly.
  • The position of the head rest can be adjusted and adapted to your needs by loosening the lever screws. Then retighten the lever screws.

4.9. Kerb climber (optional)
The kerb climber (fig. 41) makes it easier for you to negotiate steps of up to 100 mm.
Using the kerb climber requires a bit of skill and practice. Practice using the kerb climber initially on manageable terrain with an accompanying person.
Follow all safety instructions of the wheelchair when using the kerb climber.

Caution: risk of falls! Always drive directly at the kerb. Approaching it at an angle can lead to accidents.
**** It is preferable to use ramps to surmount obstacles. Only use the kerb climber if there are no ramps available to you.

• Drive up to the kerb carefully and ensure that you can clear the height of the kerb with the leg rests.
• Be sure to only drive directly at the kerb.
• The kerb should only be surmounted in the slowest driving mode.
• Carefully make contact with the kerb using the kerb climber and slowly accelerate until the front wheels have surmounted the obstacle.
• Then continue to drive slowly until the rear wheels have also surmounted the obstacle.

4.10. Mechanical parking brake
The mechanical parking brake allows you to park the electric wheelchair even when the drives are decoupled and secure it against accidentally rolling away.
Using the parking brake
To use the brake just push the brake lever forward until it snaps (fig.
42). To loosen the brake, pull the lever backwards.
Adjustment of the parking brake
If you should notice any unusual braking behaviour you have to do the following:

• Check the tread depth. Pay attention whether ther is even abrasion. If the tread depth is > than 1 mm, the tyres must be replaced by a qualified mobility dealer.
• Now check the adjustments of the brake. It must be adjusted in the way that there is a distance between the running surface of the wheel and the pivot bolt of 15 mm when brakes are open. The pivot bolt must be horizontal e.g. parallel to the ground.
• After loosening the Allen screw with a hexagon socket (5 mm) on the brake mount (fig. 43), you can position the brake correctly.
• The parking brakes effect only one driving wheel at a time.
• Once the adjustment process is completed, firmly tighten the loosened screw up again and carry out a brake test!
• The brake system should be adjusted only by a qualified mobility dealer.

Maintenance tips for users

6.1. Cleaning and disinfection
Make sure that the wheelchair is switched off before starting to clean it.

• The frame sections and panels of the wheelchair can be cleaned with a moist cloth. You can use a mild detergent for more stubborn dirt.
• The wheels can be cleaned with a wet synthetic  fiber brush (do not use a wire brush!)
• The seat, seat back and arm rests can be cleaned of dust and minor dirt with a damp cloth. Do not use aggressive cleaning agents, because they may attack the surface of the material. The cushions can be washed with warm water at 40°C and disinfected with a standard disinfectant.
• Please note that electrical and electronic components must not come into contact with water unnecessarily.

Caution! Do not use high pressure cleaners or steam cleaners.

6.2. Check before use
6.2.1. Brake check
Every time you use the wheelchair check the brake system. Move forward slowly and release the joystick. The wheelchair must come to a stop in the normal manner.
When it is at a standstill the electromagnetic brake must lock with an audible click. If you detect unusual brake behaviour, inform your mobility dealer immediately and do not use the wheelchair.
The motor brake operates correctly if you cannot push the wheelchair when it is switched off. However, if it can be moved, the electromagnetic brake is faulty. Do not use the wheelchair if this is the case. Contact your mobility dealer immediately.
6.2.2. Checking lights, indicators and horn
Before moving off in the wheelchair always check the operation of the lighting system, the indicators and horn. If you press the button and there is no response from the equipment, inform your mobility dealer immediately and do not use the wheelchair.
6.2.3. Checking the tyres
Before moving off in the wheelchair always check that the tyres are undamaged and the tyre pressure is adequate. If the pressure is too low, the tyres must be pumped up. Check the tyre tread depth at least once a month. It should be at least 1 mm. Defective or worn tyres must be replaced by the mobility dealer.
6.3. Batteries
The wheelchair is equipped with maintenance-free lead acid battery whose fluid level does not need to be checked.
If you do not use your wheelchair for an extended period, the batteries should be charged every two months, otherwise they may be destroyed by deep discharge. Make a habit of checking the battery status display on the control every time before using your wheelchair.
If the battery status display shows only the red LEDs, do not travel long distances and connect the battery charger to the wheelchair as soon as possible. We recommend charging the battery after every time the wheelchair is used.
6.3.1. Charging
Charging for the first time :
To charge the batteries to their maximum capacity proceed as follows:

• Discharge the factory-charged batteries until the LED display shows two bars.

• Charge the batteries as described below (approx. 16 hours).

• Discharge the batteries again to two bars on the LED indicator.

• Finally charge the batteries as described.
  **** Use only approved battery chargers to charge the batteries (see Technical Data). Follow the instructions for use of the battery charger.

• Before using the battery charger check that the mains connection is 230 V.

• Switch off the wheelchair first.

• Connect the battery charger to the wheelchair. The charging jack is on the side under the control (fig. 44) .

• Plug the main plug of the battery charger into the main socket (230 V).

• The charge indicator of the battery charger shows the status of the charging process (fig. 45). Superior LED-luminaire Yellow – Charger switched on

Lower LED-luminaire

Once charging is completed, disconnect the main plug and battery charger from the wheelchair.
6.3.2. Replacing batteries
When working on the batteries be very careful, do not use metal tools, do not touch the battery terminals and follow the directions of the battery manufacturer.

Caution! This work should only be done by a trained technician. Danger of electrocution!
Use only batteries approved for this wheelchair (see technical data).
Make sure that the wheelchair is switched off before starting to replace batteries.

• First remove the battery cover (fig. 46).
• First loosen the mounting and pull the battery tray out (fig. 47).
• Disconnect the battery cable. First the red terminal and then the black terminal. This does not require any tools.
• Lift the batteries carefully out by the handles.
• Install the new batteries in their correct position and connect the terminals. Note the correct colour-coding (red and black).
• Secure the battery cover with the Velcro strap and push the battery compartment back into the initial position. It latches in again automatically.
  When the batteries have reached the end of their life, i.e. they can no longer be adequately charged, they must not be disposed of with household rubbish. Old batteries are returned to the dealer when new batteries are purchased and correctly disposed of.

Maintenance tips for retailers

We recommend having the complete wheelchair inspected by the mobility dealer at least once a year. If faults or defects in the wheelchair are found, it must be returned to the mobility dealer for repair immediately.

Lifting and holding points

Due to its weight, it is preferable to use ramps for loading the electric wheelchair. If you need to lift the wheelchair nevertheless, only pick it up by the frame (fig. 48) or the holding points (fig. 49 and fig. 50). Do not grip the panel, electronics or other attachment parts. You can secure the electric wheelchair for transport with the four lugs (fig. 49 and fig. 50) in the front and back under the seat.

Transport

You can determine whether or not your wheelchair is approved for use as a seat in a vehicle for transporting disabled people by referring to the symbols on the CE sticker on the product:
Wheelchair suitable for use as a seat in a vehicle for transporting disabled people (fig. A)Wheelchair not suitable for use as a seat in a vehicle for transporting disabled people (fig. B)

All products approved by B+B for use as seats in vehicles are tested in accordance with ISO 7176-19. The tests in accordance with ISO 7176-19 were performed using restraint systems from AMF-Bruns. The correct mounting of the restraint system is a prerequisite for the safe transportation of the products in a vehicle for transporting disabled people and the basis for the approval.
Fixation points on the restraint system (fig. C)
The restraint systems from AMF-Bruns provide the ideal points for the provision of restraint force for the purpose of securing the products in the vehicle for transporting disabled people (known by the German term „Kraftknoten“, which is defined in the standard DIN 75078-2). For the purpose of providing restraint in the vehicle for transporting disabled people (fig. C), the products must only be secured at these specific points („Kraftknoten“ points). If possible, use a permanently installed car seat and its belt system. Stow the wheelchair in the luggage space. The person responsible for the transportation should be familiar with the current regulations for transportation as well as with the method of operating the vehicle for transporting disabled people and the restraint system. Anchored 4-point restraint systems must be used to secure the wheelchair in the vehicle.If you have any queries about securing your product in a vehicle for transporting disabled people, please contact the B+B customer service department on +49 (0)700/60007070.
