2. Installation
Although this chair comes complete and is virtually ready to use it is important to
remove all packaging and read the following before use.
Retractable Castors
The castors can be operated from either side of either end of the chair. Press the
pedal down to engage the castors and lift the pedal to retract the castors.
Please refer to the Operation section on page 7 for further details.
WARNING
Castors must be retracted before the chair is used and whilst patients get on or off
the chair.
Care should be taken to ensure patients do not trip over any part of the chair when
getting off.
Adjustable Foot
Fitted to the head end of the chair is an adjustable foot. This is designed to stabilise
the chair and must be set before use. The foot should be wound in/out until it is
firmly in contact with the floor whilst the castors are retracted. Check that the chair
is firm and stable and then adjust the lock nut back up against the chair leg to lock
the adjustable foot in position. Incorrect adjustment will result in the chair being
unstable and the wheel pedals difficult to operate.

Power Supply
Ensure that hand or foot switch leads are clear of the moving parts of the chair
before operation. Connect the chair to a normal domestic type power supply
observing the following notes.
WARNING
Ensure that the mains lead, plug and socket are in good condition before
connecting the equipment.
Ensure that the mains cable has a clear run and is not stretched when connected
and that no one can fall over the cable.
CAUTION
When chair is not in use switch off power supply.
Lifting and Moving
Should the chair need to be moved or lifted (for example to remove it from its
packaging) then a minimum of two people are required. The chair must only be lifted
by the metal base frame near the wheels. If the chair is upside down then it may be
carried by holding it underneath the upholstery. When turning the chair over, please
make sure the frame and upholstery are supported at all times, otherwise damage
may occur to the upholstery and gas springs.
CAUTION
Under no circumstances lift the chair by the upholstery or top sections as damage
will occur to the gas spring mechanisms.

4. Accessories Operation
A range of accessories are available as options to expand the use of the chair. The
standard recommended accessories are detailed below. Many of these can be fitted
retrospectively if required.
Paper Roll Holder
Paper roll is replaced by removal
of one or the other of the plastic
knobs, sliding the bar partially
through the leg of the holder and
then fitting the tube over the
bar. Re fit in the reverse order.
Battery Backup
Battery backup is a useful option in case of power shortages. It allows at least one
full cycle under battery power to enable the patient to get off the chair. If specified
with the chair then this feature will remain automatically charged and ready for use
in the event of a power failure.
CAUTION
Do not use the battery to operate the chair other than for one cycle. This feature is
designed to get a patient off the chair in an emergency and frequent use will destroy
the battery.
Battery operation is available as an option if required.
