1.3.6 Steps
1.3.1 Attendant pushing and self-propelled pushing :
Do ensure that the brakes are always on when the chair is not being pushed.
Always make sure that both feet are safely on the foot plates and that clothing is safely tucked out
of the way and so cannot catch in the wheels.
Always use both hands on the push handles to control the chair.
Always look well ahead to anticipate hazards such as furniture, doors or pot- holes.
Always avoid steep or uneven surfaces because the chair may tip over.
Always avoid soft surfaces be cause the castors may get bogged down.
Always be careful not to go too fast or turn too quickly and try to achieve a smooth steady ride.
PLEASE keep in contact with the person in the chair. If you stop to look in shop windows or talk
to people remember to turn the chair so that the person in the chair does not have to turn.
NEVER put on user or attendant brakes too suddenly or too firmly as this may tip the user out of
the chair.
Never use the brakes to stop the chair. The brakes are for parking purposes only.
1.3.2 Tilting by attendant :
Step 1. Make sure both the user's feet are on the foot plates and will not slip off (Make sure the
hand grips are secure and not slip off.)
Step 2. Where necessary release both brakes.
Step 3. Grasp both push handles firmly.
Step 4. Put your stronger foot on the relevant tipping lever at the back of the chair by the wheel.
At the back of the chair.
Step 5. Tell the person in the chair that you are about to tilt the chair backwards.
Step 6. Pull back with both hands and push down and forwards with the foot. This will bring the
chair onto the back wheels.
CAUTION: When a chair is tilted to about 25 degrees it will balance on it’s rear wheels and be
easy to hold. If it is tilted further back it will be difficult to hold and the person in
the chair will feel unsafe.
Lowerwithastraightback,keepyour foot on the tipping lever and lower the chair
slowly forwards to the ground withoutabump.
1.3.3 Tilting by user :
CAUTION: THIS METHOD SHOULD ONLY BE ATTEMPTED BY PEOPLE
EXPERIENCED IN WHEELCHAIR USE, AND STRONG ARMS ARE ALSO
NECESSARY. IT IS ALWAYS BETTER TO HAVE THE HELP OF AN
ATTENDANT
Step 1. Make sure both the user's feet are on the foot plates and will not slip off.
Step 2. Release both brakes.
Step 3. Grasp both rear wheel hand-bars and give a firm, sudden forward push immediately

7
before the obstacle, continue the momentum ( be ready to keep pushing ) until the obsta-
cle is mounted.
CAUTION: Leaning backwards causes the casters to rise higher BUT it is much safer to lean
forwards.
1.3.4 Going down curbs :
Please note: It is always better to avoid curbs or to use ramped curbs or opes..Where possible the
operation is best attempted with the aid of an attendant.
Going down curbs forwards with attendant:
CAUTION: This is the more difficult method and can jar the user but allows a better view of
traffic.
NEVER ALLOW THE CHAIR TO TIP FORWARDS WHEN GOING DOWN A CURB.
Step 1. Position the chair so that the front castors are near edge of the curb and make sure that
the road is clear.
Step 2. Tilt the chair as described above.(Tilting by an attendant)
Step 3. Move the chair slowly and carefully forwards. Be ready to take the weight when the rear
wheels cross the curb edge. Ensure that both rear wheels touch the ground at the same
time to avoid tipping the chair.
Step 4. Gently lower the front castors.
TRYTOAVOIDJARRINGTHEUSER.
Going down curbs backwards with an attendant:
CAUTION: This is the easier and smoother method BUT it requires the attendant to step back-
wards into the road and sensible Highway Code precautions must be taken.
Step 1. Back the chair to the curb edge and be careful that the back wheels are equally near the
edge.
Step 2. Grasping the push handles, gently lower the rear wheels onto the road. Be prepared to
control the weight as it descends and ensure that the back wheels touch ground at the
same time.
Step 3. Tilt the chair back slightly and pull the tilted chair far enough into the road so that the
castors and footrests can be lowered clear of the curb.
1.3.5 Going up curbs :
Please note: This operation is best attempted with the aid of an attendant and the best method is to
go up curbs forwards as this maintains direction of travel and is physically less demanding of the
attendant.
Going up curbs forwards with attendant:
Step 1. As the toes or footrests approach the curb .
Step 2. The chair should be tilted just high enough to allow the front castors to roll smoothly

8
onto the pavement.
Step 3. Push the chair forward until the rear wheels are touching the curb then, continuing the
movement, lift at the push handles while moving the chair forwards.
Going up curbs backwards with attendant:
PLEASE NOTE: FOR SAFETY'S SAKE WE RECOMMEND AGAINST
USING THIS METHOD.
BECAUSE THE USER MAY FALL OUT OF THE WHEELCHAIR
1.3.6 Steps :
PLEASE NOTE: AVOID FLIGHTS OF STEPS PARTICULARLY IF NO
EXTRA HELP IS AVAILABLE. USE RAMPS OR LIFTS IF AVAILABLE.
Down steps or up steps:
Two attendants are necessary, each capable of carrying at least half of the combined weight of the
person and the wheelchair.
Each helper should bend at the knees and grip the main frame: with the front hand just under the
front of the seat, with the back hand holding the push handles. (See figure 1.1 )
NEVER HOLD ON TO MOVABLE PARTS.
ALL LIFTING SHOULD BE DONE WITH A STRAIGHT BACK.
Straighten legs to lift the chair. Carefully carry it up or down steps; be aware of how you place
your feet -- do not cross them and trip yourself up.
2. Fault checking and maintenance :
Maintaining the chair in its correct working order is essential; the frame is of an extremely durable
aluminum alloy and the accessories are designed for strength, however checks should still made to
ensure long term performance.
Below is a list of checks and the frequency with which we recommend they should be made,
following these guide lines and exercising common sense prevent problems before they arise.
Replace worn or damaged parts, wash fabrics.
''A'' checks should be carried out every month.
''B'' checks should be carried out every week.
''C'' checks should be carried out every time the chair is used.
Frequency Open the chair--all movements should be free throughout the Folding Range
A Examine the seat & backrest covers for wear, damage or staining.
A Examine retaining screws for tightness and general condition.
Replacement of fabrics should be carried out by your approved repairer.

9
A Examine armrests for ease of movement -- elevating.
A Examine armrest locking assembly for damage or wear and check that the armrest is
securely retained.
A Make sure foot plate adjustment screws are securely tightened.
A Examine heel loops or leg belt for damage or excessive wear-- Particularly the strength
of the leg belt's adhesive pads.
A Examine the backrest release lever for effective locking.
A Open/unfold the chai
r
-- this operation should be easy and smooth.
A Examine upholstery retaining screws for tightness and general Condition
Replacement of fabrics should be carried out by approved technician.
A Examine calf strap for damage or excessive wear - particularly the strength of the
Velcro pads.
A Examine the footrest release lever for effective locking.
A Examine the armrest release lever for effective locking.
A Check pivot point for undue slackness due to loose nuts or worn parts.
A Examine the frame structure for damage.
A Check castors for free rotation of castor wheel and castor assembly.
A Examine castors for wear in the bearings/mountings and for trie wear or damage.
Replacement of castors should be carried out by your approved repairer.
Frequency Lift the Front of the Chair and the Push Handles on the Floor
A Examine each spindle for bending at the location in the frame.
A Check rear wheels for free rotation and for wear in the bearing/mountings.
A Check trie tread depth. Recommended minimum depth is 1mm.
B Check trie pressure. Failure to keep tries at the correct pressure will reduce the braking
efficiency. trie pressures are located on the trie wall.
C Examine brakes, checking for wear and damage and misalignment.
Replacing or adjusting the brakes should be carried out by your approved repairer.
C Check that the hand grips are not damaged and are securely bonded to the push handle.
C Check tipping lever pads or anti-tips are not damaged and are securely bounded to the
tipping levers.
C Where fitted, check that the anti-tipping bars/wheels are not damaged and are securely
mounted.
C Check the tipping lever pads are not damaged and are securely bonded to the tipping
levers.
