1 Introducing Your Stairlift
Congratulations on becoming the owner of a Bison 50 Stairlift, which has been
manufactured specifically to meet your requirements. It has a 12-month Bison warranty
and will provide you with many years of reliable service.
It is important for your safety that you study this manual to completely familiarise yourself
with your Stairlift.
2 Main Components

3 Description of Operation
Your Stairlift is switched on and off using the
On/Off Holding Switch (2).
The Stairlift is moved up and down the stairs by
the user operating the Direction Controller on the
armrest (1).
For your safety, there is a slight delay between
the Stairlift changing direction or restarting in the
same direction.
When not in use please ensure that the seat
belt is kept clear of the rail.
3.1 Charging Your Stairlift
The Stairlift batteries are recharged from charging points when the Stairlift is in its parked
position at the top and bottom of the stairs. The charging points are connected to a 30 volt
power supply fed from the mains electricity.
IMPORTANT After installation and demonstration are complete, it is important the lift
batteries are fully charged to achieve optimum performance of the lift. The lift should be
moved to either rail charge point and left on charge for a minimum of 8 hours. This is a
one off operation, following this initial charging period the batteries will be “conditioned”
and the lift ready for normal operation.
If there is a mains electricity supply failure, or if the supply to your Stairlift is switched off, it
will continue to operate for several journeys. However, the batteries will eventually lose
their charge and the Stairlift will not operate.
To keep batteries fully charged, the mains electricity supply should always
be switched on and the lift parked on its charge points. If the batteries have
lost their charge because the mains electricity supply has been switched
off, or interrupted, allow them to recharge for a minimum of 2 hours, before
using the lift. If the batteries are not being recharged you will see this
flashing symbol, on the fault indicator, and hear a bleep alarm.
The Symbol will stop flashing when the lift is on a powered charge point

3.2 Safe Operation
WARNING
• Do not allow children to play with the Stairlift or the remote controls.
• Ensure pets are clear of the Stairlift at all times.
• Do not exceed the safe weight limit the Stairlift is designed to carry (see the label
on the carriage).
• Always use the seatbelt.
Before operating your Stairlift, ensure that
there are no obstructions on the staircase. The
Stairlift is fitted with seven safety edges:
1 & 2 - each side of the carriage.
3 & 4 - each side of the footrest.
5 - under the footrest.
6 & 7 - each side of the carriage above the rail.
If these encounter any obstruction, the Stairlift
will stop immediately. Move the Stairlift back in
the opposite direction and remove the
obstruction.

5 Additional Options
5.1 Powered Swivel Seat
To sit onto a powered seat at the top of the stairs move the Stairlift to face
you by operating the remote control Ï button. Sit in the seat and fasten
the seatbelt then press the Direction Controller to move the Stairlift down.
The seat will swivel to its operating position and move down the stairs.

The Stairlift can be called to the bottom of the stairs by using the remote control Ð button.
5.2 Remote Direction Controls
The Stairlift must be in its correct operating condition, with the seat
facing forward and switched on with the On/Off Holding Switch, before

Stairlift and operate hinged rails or platforms when fitted. Press the Ï
or Ð buttons continuously until the Stairlift stops at the end of its travel.
Do not leave the Stairlift parked part way up the stairs because the
batteries will not be re-charged in this position
Should the user not be able to easily operate the direction controller on
the end of the seat arm, they can carry the hand held remote control
with them whilst travelling on the lift, and operate the lift independently
of the arm control.
