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.
• The accompanying person should be physically and mentally
capable of operating a wheelchair.
• Never use the wheelchair under the influence of alcohol or other
drugs.
• Please make sure that all parts have been properly installed before
using the wheelchair.
• Never lift up the wheelchair at parts which are not fixed firmly (the
armrests or legrests).
• Make sure that the screwing axle/floating axle are tightly in the
axle holder, otherwise there is risk of injuries.
• Please note, 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.
• Please note there is a risk of entrapment between moving parts
when adjusting, using and maintaining the wheelchair.
• Please seek the help of an assistant person when going over
obstacles, steps, etc. Use the tip assist (see overview of wheelchair)
to tip the wheelchair appropriately.
• Steps and larger obstacles may only be crossed with the help of at
least two assisting persons. For this, use lifting points 1 and 2 (see
overview of the wheelchair). If equipment such as ramps, lifts or
step climbing aids are available, these should be used.
• When driving on an incline or slope, it is necessary to be aware that
a risk of tipping exists even at low angles, depending on the axle
position setting. The use of anti-tippers is highly recommended.
• Avoid running against obstacles (steps, kerbs) without braking or
moving down steps.
• When getting into or out of the wheelchair, apply both parking
brakes.
1. Preliminary remark
Dear user,
By purchasing your Bischoff & Bischoff Pyro light Optima folding
wheelchair, you are getting a top German product which sets new
standards with its variability. The Pyro Start Plus is made for indoor
and outdoor use.
The wheelchair is offered in the Pyro Light Optima (model no.: 1331)
and Pyro Light Optima XL (model no.: 1321) models. The Pyro Light
Optima XL is popular due to the high user weight with double cross-
brace and reinforced frame.
These operating instructions intend to help you to familiarise yourself
better with the operating and the handling of your wheelchair. Before
using your new 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 wheelchair. 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.
1.1. Signs and symbols
Important! This is especially useful information on
a given subject.

4.2.4 Swinging away the legrests
To make it as easy as possible to get into and out of your B+B folding
wheelchair, you can easily swing the legrests outwards or inwards if
needed without having to remove them (fig. 8).
•Pull the handle. This opens the locking device.
•Now you can swing the legrests outwards or inwards.
•If necessary, fold the foot plates upwards first.
To return to the original position, simply swing the legrest forwards
until it locks into place.
When standing up/sitting down on your
wheelchair, never stand on the footrest, danger of
falling or tipping!
4.2.5 Setting the legrest length
The length of the legrests can be adjusted in five 20 mm steps up to
a total of 80 mm. To do so, remove the Allen bolt (4 mm) and set the
legrest as required (fig. 9)
4.2.6 Angle-adjustable foot plates
The angle of the foot plates can be adjusted:
•Unscrew the Allen bolt and adjust the foot plate to the required
position by rotating the toothed ring.

4.2.7 Width of the foot plates
You can adjust the width of the foot plates.
•Loosen the fastening screw on the foot plate, then you can adjust
the foot plate to a narrower or wider setting (105 mm to 155
mm).
•Then secure the foot plate by firmly tightening the fastening
screw (Fig . 11).
4.3. Side parts
In order to be able to get in and out more easily, both side parts and
the arm rests can be swung backwards. Operate the locking lever using
light finger pressure (fig. 12) and swing the side part backwards at the
same time (fig. 13).
Do not use the side parts to lift the wheelchair!
To lock the side part, first swing it forwards and allow it to click into
place with light pressure on the armrest
When moving the side parts, ensure that no items
of clothing or other items can get jammed. Before
use, check for firm attachment of the side parts!
4.3.1 Removing the side parts
To get in or out the wheelchair, removing a side part can be helpful. To
do this, loosen the front locking lever as described previously. You can
then loosen the back lock by pulling on the lever. Now you can simply
remove the side part. Re-assembly is then carried out in reverse order.

4.4. Armrests
4.4.1 Height of the armrests
You can easily adjust the height of the armrest. To do so, pull the height
adjustment lever on the side part and pull the armrest up or down
(Fig. 15). When you release the lever, the armrest latches automatically.
4.4.2 Position of the armrests
You can shift the armrests further forwards or backwards. To do this
you operate the knob located at the side of the armrest and pull this
towards the front or the back. When you let go of the knob, the armrest
automatically locks into position.
4.5. Seat
4.5.1 Seat depth
The seat depth can be adjusted in five steps. This allows the seat depth
to be changed up to 50 cm. First remove the side part bracket and the
backrest bracket by loosening the fastening screws (fig. 17).
Caution. Danger of tipping! If you adjust the
driving wheel forwards or the backrest backwards,
the danger of tipping is increased significantly.
Anti-tip wheels or a wheelbase extension are
necessary. Check the settings first with a
helper. Only use settings that you feel safe with.

Afterwards, remove the Allen bolts at the back on the seat cover
(fig. 18).
Pull the adapter out to the required position and then retighten the
bolt. Then pull back the rear part of the seat cover and connect this
again with the front seat cover using the Velcro tape (fig. 19).
Reattach the backrest to the wheelchair frame. Position it as close as
possible to the seat. Afterwards, mount the bracket so that the side
parts click into place correctly.
For your safety, please use the wheelbase extention
when the largest adjustments for seat depth 50 cm
are used.
4.5.2 Seat height
In only a few steps you can adjust the seat height to suit your needs.
1. Drive wheel height
Take off the drive wheel (see 4.11) to make it easier. To adjust the
height of the drive wheel and, consequently, to raise or lower the
height of the whole wheelchair, you first have to remove the drive
wheel brackets. You can loosen the fastening nuts of the axle bracket
with a spanner (fig. 20).
Now you can remove the bracket and fasten it at the desired height.
Screw the nut tight again and fasten the drive wheel.

2. Front wheel height
The height of the front wheels can be adjusted to three levels. Loosen
the Allen bolt (fig. 21) and pull out the wheel axle. Move the front
wheel to the desired height, then tighten the bolt again.
3. Angle of the steering wheel axle
The angle of the steering wheel axle can change as a result of changing
the height of the drive wheel and/or the front wheel. This should,
however, always be at right angles (90°) to the floor (fig. 22).
First loosen the locking device by loosening both Allen bolts on the
interior side (fig. 23).
You can then adjust the angle with the aid of the two grub screws
(fig. 24). Subsequently both attachment bolts on the inside are to be
tightened up.
4. Adjusting the parking brake
With any change to the height of the drive wheel, the parking brake
has to be newly adjusted (see 4.7).
4.5.3 Seat Angle
If you incline the seat of the wheelchair towards the back, you will be
sitting more deeply and firmly in the chair. To incline the seat towards
the back, attach the quick-release axle in a higher position. If you wish
to incline the seat towards the front, fix the quick-release axle in a
lower position. Fixing the quick-release axle is done in the same way
as in 4.5.2.1.

4.6. Wheel base
Caution. Danger of tipping! If you adjust the
driving wheel forwards or the backrest backwards,
the danger of tipping is increased significantly.
Anti-tip wheels or a wheelbase extension are
necessary. Check the settings first with a
helper. Only use settings that you feel safe with.
The stability of the wheelchair is improved by lengthening the
wheel base. On the other hand, shortening the wheel base improves
manoeuverability. A shortening of the wheelbase is only recommended
for practised wheelchair users.
To set the wheelbase, loosen the four fastening screws that secure the
wheel attachment.
The wheelbase can be adjusted in four stages. Fasten the wheel
attachment afterwards in the cut-outs provided. Ensure that all four
screws are securely tightened. To increase the wheelbase, a wheelbase
extension can also be used.
When changing the wheel base, a subsequent
adjustment of the parking brake is also absolutely
necessary!

4.7. Brakes
4.7.1 Setting the parking brake
To lock the brake, simply push the brake lever forwards until it locks
(fig. 26). To release the locking brake, simply pull the brake lever
backwards (fig. 27).
4.7.2 Adjusting the brakes
If you notice that the available braking effect is no longer sufficient or
is uneven, proceed as follows:
• Check the tyre profile depth. At the same time, check for even wear
of the tyres. If the profile depth in the middle of the tread is less
than 1mm, the tyre must be changed. If you have the necessary
technical experience you can change the tyre yourself, if you do not
feel confident to do this yourself, your specialist retailer will be able
to help you.
• Now check the adjustment of the brake. This must be set so that
the gap between the surface of the wheel and the braking bolt
is 15 mm with the brake off (fig. 28). The braking bolt must be
aligned horizontally, that is parallel to the ground surface.
• After unscrewing the two rounded head bolts with 5 mm Allen
head on the brake mounting (fig. 29), you can position the brake
correctly.
The brakes only operate on one driving wheel each!
Ensure that both drive wheels have the same tyre
pressure with pneumatic tyres to achieve good
directional stability!
After completion of the setting process, retighten
the loosened bolts and test the brakes!

4.8. Backrest
The tension of the backrest can be adjusted to enable you to sit
comfortably in the wheelchair. Additionally the height of the backrest
can also be adjusted.
4.8.1 Backrest cover
The tauter you adjust the backrest cover, the harder it feels. First remove
the backrest padding that is attached by Velcro tape (fig. 30).
Then you can adjust each of the belts so that they are firmer or less firm
(fig. 31). To lessen the tension on particular parts of your back, loosen
the belt there a little. Now you have to re-secure the back padding by
means of the Velcro tape.
4.8.2 Backrest height
To adjust the backrest height it is recommended that the side parts and
the back padding are removed first. You can then loosen the screws on
both sides (fig. 32) and adjust the frame to the desired height. Then
put the screws back into the holes provided and screw them firmly in.
4.9. Push handles
The height of the push handles can be adjusted to make it comfortable
for an accompanying person to push you. Loosen the lever screw
(fig. 33) on the push handles and adjust them to the required height.
Then firmly tighten the lever screws again to lock the push handles.

axles (Ø12mm) (fig. 34). The Pyro light Optima model comes with
quick-release axles as standard. (For quick-release axles, see Section
4.11)
Check that the wheels sit firmly each time they
are attached!
4.10.1 Drive wheels
Rubber tyres with an inner tube or PU tyres (puncture proof, no valve)
size 24“ x 1 3/8“ are fitted as standard on your Pyro Light. If they
become worn or defective, themobility dealer should be requested to
undertake the repair.
To ensure optimum operating safety of the brakes,
the pneumatic tyres must have a
pressure of 300-400 kPa (3-4 bar).
4.10.2 Steering wheels
Rubber tyres with an inner tube or puncture proof tyres (without valve)
with a diameter of 8“ x 1 1/4“ (Pyro Light Optima XL 200 x 50 mm)
are mounted on your Pyro light Optima as standard. If they become
worn or defective, the authorised mobility dealer should be requested
to undertake the repair.

4.11. Quick-release axles
To achieve significantly easier transport of your wheelchair, the wheels
are equipped with quick-release axles as standard:
• Press on the locking button of the quick-release axle with a finger
and remove the wheel (fig. 36).
• When reattaching the wheel, simple push the wheel back into the
mount. At the same time, press the locking button.
Ensure when pushing back in that the quick-release axle is pushed!
Check after pushing back in that the wheel is firmly attached by
pulling it towards you without operating the locking button of the
quick-release axle.
4.12. Tipping aid
The tip assist can be used to help an accompanying person overcome
obstacles such as kerbs. Hold the wheelchair firmly at the push handles
with both hands. Then with one foot you press on one of the tip assist
(fig. 37), at the same time pushing downwards with both hands.

• When going down stairs, the helper who is below brakes by pushing
the wheelchair right against the steps. The helper above holds the
wheelchair at the push handles, secures it and holds it in the right
position. The wheelchair should roll down step by step.
7.4. Driving the wheelchair
Sit in your B+B wheelchair. Make sure you are sitting as far back as
possible. The push rims on the drive wheels are used to move the
wheelchair.
Moving and braking are achieved via the push rims on the drive wheels.
Practice moving the wheelchair carefully at first until you are familiar
with it and the way it behaves.
Wheelchairs have only a limited ability to resist tipping and sliding.
Particular care is necessary when braking and moving onto, or turning
on inclines. Leaning a long way out of the wheelchair increases the
danger of tipping.
To overcome obstacles more easily, the wheelchair must be tipped by
the accompanying person.
You can hang shopping bags or a rucksack on the backrest frame.
Never stand on the footrest!
Risk of tipping!
For obstacles and stairs with more than three steps,
two accompanying people must help.
7.2. Entering and leaving from the
front
• First fold the foot plates up or remove the leg rests.
• Move the Pyro Light Optima and the current or intended seat
together front to front if possible and decelerate the Pyro Light
Optima.
• If you wish to move from another wheelchair or room chair, lock it
by setting the parking brakes.
• Now slide onto the seat by turning your body around.
• Then move the arm rest and leg rests to the original position.
7.3. Negotiating stairs and high
steps
• Helpers must only take hold of securely fitted parts of the frame.
The lifting points are shown in Figure 42 depending on the model
equipment.
• When going up stairs, the helper behind the wheelchair pulls
the wheelchair over the step, holding it by the securely mounted
handles.
• The helper who is below takes hold of the front frame tubes and
stabilises the position. At the same time, he pushes the rear wheels
of the wheelchair against the steps.
42
Frame and push handles are the only places where
you can get hold of the wheelchair to transport it.
Never lift up the wheelchair at the armrests!
Please note that the risk of tipping over backwards
is significantly increased by hanging bags and
rucksacks on the backrest.

To get over obstacles more easily, the assisting person must position
the wheelchair at the correct angle to the obstacle by pressing on the
tip assist.
Before getting in or out, the parking brake should get locked. Use
outside of the home should only be undertaken with sufficient
experience. When possible, somebody should accompany you.
The static stability of the basic model is 7° (ca. 8 %). The critical
obstacle height at the basic model in unfavourable situations is 23
mm (maximum centre of gravity shift)
The critical obstacle height is the height in which the centre of gravity
(with the user) is right vertical over the obstacle rim. If the user tries to
put the wheelchair with the help of the driving wheels on the obstacle
without having shifted the centre of gravity forwardly, the wheelchair
will tip over backwardly.
According to STVZO 66/1 (German Road Traffic Act) of 01.01.1981,
hand propelled wheelchairs require permanently attached lighting to
participate in public road traffic (including on footpaths).
This consists of (passive):
• two red reflectors to the rear
• two amber reflectors on both sides.
If the wheelchair is used after dark, the following are necessary in
addition (active):
• one white light forwards
• one red light backwards.
These lights must work from an electrical circuit independent of the
movement (batteries) power.

9. Transport
9.1. Transporting the wheelchair
To transport the wheelchair as convenient as possible, all detachable
parts (footrests, wheels, accessories) must be removed and the wheelchair
folded.
9.2. Seat in disabled vehicle
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)
The wheelchair has also been marked with symbols on the frame which
quickly show you and your transport service provider if it is suitable for
transport in wheelchair accessible vehicles and where the fastening
points are located:
Wheelchair not suitable for use as a seat in a vehicle for
transporting disabled people (fig. C)
Fixation points on the restraint system (fig. D)
All products approved by B+B for use as seats in vehicles are tested in
accordance with ISO 7176-19. The tests in accordance to 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.
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. D), 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.
