give added strength.

trained technician.

Operating Instructions
Armrests
Armrests have been fitted to either side of the chair, these aide comfort while sat in the chair, and
also help the patient to stabilise themselves while getting in or out of the chair.
The armrests can also be lowered to allow a patient access from the side as the armrests lower
to a position below the seat level. This can easily be achieved by pulling the *plunger, to
disengage, then lower the armrest.
To raise the armrest, simply pull the armrest upwards. It will click as the plunger engages into
position. Ensure the plunger has engaged in the locator and the armrest locked into position.
Plunger

Each armrest has 1 plunger.
IMPORTANT NOTE: Armrests have
not been designed to be weight
bearing. They are for the comfort of
patient transport only.

Operating Instructions
Removable Footrests
Designed for patient comfort and ease of use the footrests can be removed completely (Fig 1) if
not required.
To remove the footrests, loosen the threaded lobe knob on the front side of the chair (Fig 2) by
unscrewing in a counter clockwise direction. (You do not need to fully remove the knob.
Loosening it will allow removal of the footrests.) Pull the footrest away from the chair in a
horizontal motion removing the footrest and the supporting arms.
To refit the footrest, simply align the two supporting arms and push the footrest back into place.
Once in place, rotate the threaded lobe knob in a clockwise direction to tighten and secure.
For easier access for the patient the footrests can be rotated upwards (Fig 3).

IMPORTANT NOTE:
DO NOT allow patients to stand
on the footrests when getting in or
out of the chair, as the chair will be
unstable.
In addition, footrests have not been
designed to be weight bearing.

Folded Position
To place chair into the folded position, rotate the footrests into an upright position (Fig 1), place
hands in gap between the seats and lift the seat frames into an upright position (Fig 2). There is
no locking mechanism, the weight of the chair keeps it in the folded position.
To open the chair, from its folded position, stand behind the chair and simply pull push handles
apart. The chair will open easily on its own.
IMPORTANT NOTE: The armrests must be in their down position for folding.

It is recommended that the chair should be serviced regularly, but only by Wardray Premise
trained engineers, as they will carry the correct spares to guarantee the continued safety and
compatibility of the chair. Failure to comply with this will invalidate your warranty and could
compromise the MR compatibility and safety of this product.
Recommendations
Always refer to and comply with your organisations patient movement policy.
We recommend that all staff using the chair receive appropriate manual handling training and
that appropriate risk assessments are completed.
Additional patient handling equipment such as slings / rota stands / stand aids should be
considered as part of your risk assessment.
It is important that the portering chair is pushed at all times and not pulled. Pulling the chair
whilst occupied could result in the patient being ‘tipped out’.

General Maintenance
It is strongly recommended that the following checks be carried out on a weekly basis by facility
personnel to ensure trouble free operation of the MR4588 bariatric portering chair.
 Check that the portering chair runs straight (no excessive drag or pull to one side).
 Ensure that there is no excessive side movement of rear wheels when the portering chair is
lifted and wheels spun.
 Inspect seat and back upholstery for sagging, cracking and any other obvious signs of
damage or contamination. Report any damage.
 Inspect hand grips for wear, looseness and / or deterioration.
 Inspect for any broken or loose parts.
 Inspect castors for damage. Remove any debris that may have become caught in the brake

expectancy of the castors if left unattended.
 Check for correct operation of brakes.
 Check armrest for correct operation and damage to padded section.
