1. Preface

Dear user,

You have selected a high-quality wheelchair from Bischoff
& Bischoff. Thank you for your trust in our products.

The wheelchair has been designed to give you many
advantages and to meet your needs. The wide range of
adjustments for seat depth, seat back height, knee angle,
seat width, seat-back angle, seat angle and lower-leg
length make it easy to adjust the Triton to the user's indi­vidual body size.

The Triton is designed for use inside and outside.

Please read and follow the instruction manual carefully
before using your new wheelchair for the first time. The
manual is an integral and important component of the
wheelchair. Keep the instruction manual at hand and
include with the wheelchair when you transfer it to another
owner.

Repairs and adjustments require specialised technical
training and must be carried out by Bischoff & Bischoff
authorised dealers only.

1.1. Signs and symbols

You have selected a high-quality wheelchair from Bischoff
& Bischoff. Thank you for your trust in our products.

Caution! Indicates specially safety-relevant
instructions. Follow instruction manual.

Important! Indicates particularly useful
information in the specific context.

6

Before using the wheelchair check that all attached com­ponents are correctly fastened. Practise using your new
wheelchair on a small, flat area first to prevent falls and
hazardous situations.

We recommend having an assistant with you at this time.
The wheelchair must not be used to transport more than
one person or loads.

Note the intended use. Never operate the wheelchair
under the influence of alcohol or other substances that
could detract from your alertness or physical and intellec­tual acuity.

Please note that changes in the balance of the wheelchair
by body movements or the load may increase the risk of
tipping. Please note that padding that is exposed to direct
sunlight may become hot and burn your skin if it comes
into contact with it. Cover these parts or protect the
wheelchair from direct sunlight.

We recommend using leather gloves when using the
wheelchair outdoors. This improves the grip and protects
your hands and fingers from dirt and injury.

2. Important safety
instructions

2.1. General safety
instructions

English

Triton

Bischoff & Bischoff GmbH • 03.01.2012 7

Parking brake

The brakes that actuate directly on the tyres of the wheels
are to be used as parking brakes only, i.e. they must only
be actuated when the wheelchair is at a standstill and
must never be used to reduce the speed of the wheelchair.

When using the hand rims for slowing down from speed or
descending long slopes, your fingers and hands will quickly
become hot. Be careful of burns!

Drum brake (optional)

The drum brake is designed exclusively for operation by an
assistant pushing the wheelchair. The drum brake can be
used as a parking brake and also for slowing down the
wheelchair gently.

2.2. Brakes

2.3. Anti-tilt wheels

The anti-tilt wheels prevent the wheelchair from tipping
backwards. Please note that for using the wheelchair the
anti-tilt wheels are of only limited use on rough areas,
hoists and ramps. Make sure that the clearance to the
sides, above and below is sufficient.

2.4. Tyres

Make sure that the tyres have sufficient tread (>1 mm) at
all times. If the tread is too worn down, safe use of the
wheelchair cannot be guaranteed.werden.

8

Always use ramps to negotiate obstacles (e.g. kerbs, steps
etc.). Do not travel into an obstacle (step) without braking
or jump down from steps.

2.5. Obstacles

2.6. Ascents and des­cents

Please note that if the seat back is adjusted to an extreme
tilt, your wheelchair may tip backwards on even a moderate
slope. Negotiate inclines and slopes only with an assistant
with these adjustments. Use the anti-tilt wheels to help
prevent the wheelchair from tipping backwards.

2.7. Safety in vehicles

Please note that wheelchairs must not be used as seating
in any vehicles. The user must transfer from the
wheelchair to a standard vehicle seat.

2.8. Using public
footpaths and roads

The wheelchair is designed for use indoors and outdoors.
Always follow the traffic regulations on public streets.

tyre pressure must be 300 - 400 kPa (3-4 bar).
The brake will not operate efficiently if the tyre
pressure is not correct.

The Triton is fitted with a tyre brake that can be operated
by the user. This must be used as a parking brake only. It
is not suitable for use as a brake for stopping or slowing
the wheelchair! This is done with the hand rims by the
exercise of light pressure with the flat of the hands. Once
the wheelchair has been brought to a standstill by this
method, set the two wheel brakes by pushing the brake
lever forward. The wheelchair is now safely braked.

(optional)

The Triton can optionally be fitted with a drum brake,
which can only be operated by an assistant with the brake
levers mounted on the handles.

The drum brake can be used as a parking brake and as a
service brake. As a service brake it can be used to slow the
wheelchair gradually. The locking function is used for par­king the wheelchair.

• To set the brake just pull the brake lever and press the

locking lever upwards.

• To release the parking brake, just pull the brake lever

briefly (the lock is released automatically).

The braking force is adjusted with the adjusting screw for
optimum braking performance. The braking force is increa­sed by screwing the adjusting screw out and reduced by
screwing it in.

• Unscrew the adjustment screw until you can hear

friction noise when the wheel rotates.

• Screw in the adjustment screw until you can no longer

hear the noise. The wheel will rotate freely.

• After the adjustment the adjusting screw is locked by

tightening the lock nut.

When the brake is released, the wheelchair should be
easy to move in a straight line without friction noises. If
you detect unusual brake behaviour, inform your dealer
immediately and do not use the wheelchair.

• Check that the seat and back rest covers are undamaged
and clean. If they are dirty, clean them as directed in
the cleaning instructions. If you find any damage,
contact your dealer.

• Check that the folding mechanism and all moving parts
