4. Preparing for use
The wheelbase is supplied ready for use. The following pre-delivery procedures should be
carried to check that the wheelbase has not suffered damage during transit and that all features
operate satisfactorily.
Warning: - When opening or folding the wheelbase, ensure that you hold the frame so that
you avoid any danger of catching your fingers in moving parts.
4.1 Unfolding and folding: - make sure all items below are working properly
4.1.1 Backrest supports: - Make sure the locks operate positively and freely
Standing behind the wheelbase lift the backrest locking pins using the
ball shaped handgrips at the bottom of the backrest tubes. Turn them
so that they lock into the groove arrowed opposite
Lift backrest supports vertical.
Lock the supports in position by moving the handgrips out of the
arrowed groove (see photo) and making sure they have moved to the
bottom of the slot in the backrest tube.

4.1.2 Push handles: - Check adjustment and security.
The push handles are fitted to the wheelbase prior to delivery. Make sure that they are in
place and that two thumbscrews are fitted to each push handle.
To adjust the height of the push handles unscrew (turn anti clockwise) the two thumbscrews
at either side and near the top of the backrest. Lift or lower the push handles to the height
required then retighten (turn clockwise) the thumbscrews.
To prevent the push handles moving in use these screws must be tight. Check tightness daily.
To make it easier for some people to push the wheelbase when the backrest is in its lowest
position the push handles can be reversed so that the handgrips are pointing forwards. Simply
unscrew the thumbscrews, turn the push handles so they are pointing forwards and refit the
thumbscrews. Take care not to get the screws cross-threaded when refitting them
4.1.3 Unfolding the wheelbase: - Check operation of folding mechanism
Standing in front of the wheelbase place palms of hands on each side of the seat rails then
press down to open the wheelbase. Take care to hold your fingers towards the centre of the
seat to avoid catching them on the wheelbase frame.
4.1.4 Backrest spreader bar: - check operation
Standing behind wheelbase lift the chrome “spreader” bar,
which is on the right hand backrest support, upwards and
place its slotted end onto the peg on the left hand backrest
support (arrowed). It may be necessary to push the backrest
supports apart when doing this.
4.1.5 Armrests: - Check fitting
Note: - Only applies when armrest is supplied as an optional extra.
Standing at the side of the wheelbase place each armrest into
the holes in the wheelbase frame. (See photo). Make sure they
are pressed into the wheelbase frame properly.
Make sure that the tube supporting the armpad extends to the
rear of the wheelbase.
To fold the wheelbase, reverse the above.

4.2 Fitting and removing footrests
4.2.1 Fit the footrest: - check operation
Note: - Only applies when footrests are supplied as an optional extra.
To fit the right hand footrest, stand in front of the
wheelbase. Remove the spring clip from the lower hinge
pin on the side of the wheelbase. Making sure the footplate
is facing in towards the centre of the wheelbase place the
footrest onto the hinge pins. (See Photo opposite). Replace
the spring clip. Swing the footrest towards the centre of the
wheelbase until it locks in place.
Repeat for the right hand footrest.
Adjust the height of the footrest by
loosening the nut on the support tube
using a 10 mm spanner. Move the footrest to the desired height then
retighten the clamp nut. (See picture opposite).
The angle of the footplate can be adjusted by loosening the lock nut,
which is at the bottom of the footplate support tube. Screw in or out the
footplate stop; until the desired angle is obtained then retighten the lock
nut. (See picture opposite).
4.2.2 To fold footrests back against the wheelbase frame.
Lift up the footplate so that it is vertical then push on the silver
catch on the footrest. The Footrest will then swing back. (See
picture opposite).
To return the footrest ready for use simply swing the footrest
forwards, the catch will lock automatically, and lower the
footplate.
4.2.4 To remove footrests.
Remove the spring clip from the lower hinge pin. Swing the footrest to the side and holding
the curved part of the support tube lift upwards.

Note: - The spring clip prevents the footrests being lost. However, if the user needs to
regularly remove the footrests the spring clip can be discarded.
4.3 Tilt in Space
Check Tilt mechanism: - Move the seat through its full range of adjustment.
The angle of the seat and backrest can be adjusted to any angle between the upright and fully
reclined position.
To recline the seat, put the brakes on
and stand behind the wheelbase.
Holding both push handles squeeze
the operating lever (see photo
opposite) and push down evenly on
both handles. Release the lever when
the seat is at the desired angle.
To bring the seat upright put the
brakes on and stand behind the
wheelbase. Holding both push handles
squeeze the operating lever (see photo
opposite) and lift evenly on both
handles. Release the lever when the
seat is at the desired angle.
Important: - Always hold and move both push handles together when adjusting the seat
angle.
4.4 Tyres and Brakes
The tyres do not require any attention other than being cleaned with a damp cloth when dirty.
Test brake operation by moving both levers forward as far as they will go. The wheels should
now be locked. If the wheels move the brakes need adjusting. Adjust them as instructed in
section 7.3 below.
To avoid making flat sections on the tyre never leave the brakes on for long periods i.e.
overnight or during storage.
5. Cleaning
Make sure the wheelbase is clean and well presented. If there is any dirt it should be cleaned
off using a damp cloth and then dried thoroughly.
For more stubborn stains wipe with a damp cloth using a mild solution of warm water and
soap.
Never use furniture polishes or spirit to clean the frame.

The Fabric parts of the Wheelchair are made from Ambla fabric. Ambla is resistant to most
mild acids, alkalis, drinks and household stains. Clean with a damp soapy cloth and rinse well
with clean water. A soft brush can be used for heavy soiling. Do not use solvents, bleaches,
abrasives, synthetic detergents, wax polishes or aerosol sprays.
6. Maintenance
Should a problem be found when carrying out the regular checks, it should be immediately
reported to the issuing authority or repairer.
6.1 Routine maintenance
The user or their family can easily carry out the following tasks. No tools are required.

Someone who is a competent tradesman or repairer should only carry out this work. If a
major problem is found do not allow the wheelbase to be used until it has been corrected.
1) Fold and open the wheelbase. Check that all movements through the folding range are
free. Examine frame for any damage.
2) Examine nuts, bolts, pivots, sliders and frame plugs for tightness and general condition.
3) Examine push handle retaining knobs and check they are hand tight.
4) Examine footrest heel loops (If fitted) for damage or excessive wear and that the retaining
nuts are tight.
5) Examine brake assemblies for wear, damage and adjustment.
6) Examine Tilt and Fold mechanism and check operation of reclining mechanism.
7) Examine front castors and rear wheels for free rotation and security.
7. Repairs

Factory replacement components should be used in all repairs, these are available from
Tendercare.
7.1 Front castors: - Replace the complete assembly if damaged or worn.
1) Using a 24mm spanner unscrew the hexagon nut at the top of the castor swivel until the
castor is removed.
2) Before fitting new castor apply LOCTITE thread locking compound grade 241 to the
thread on the castor stem. Screw the stem into the wheelbase mounting and tighten to
54Nm.
3) The castor should rotate under its own weight if it does not, rotate the castor forks a
number of times to ease the mechanism.
7.2 Rear Wheels: - Replace if damaged or worn.
1) Unscrew the axle retaining nut using 19mm spanners. Remove the washers and pull the
wheel assembly from the wheelbase.
2) Place the spacer taken from the old wheel onto the axle of the new wheel. Insert axle into
the wheelbase-mounting hole then fit a new 12mm friction washer onto the axle. Apply
LOCTITE thread locking compound grade 241 to the axle thread and secure with a new
M12 nut. Tighten to 45Nm. When fitted make sure the wheel rotates freely and the brakes
operate properly.
Important –Always fit new steel locking washer and nut.
7.3 Brake adjustment
The tyres are made from a solid material and do not require any attention other than being
cleaned with a damp cloth when dirty.
Test brakes by moving both brake levers forward as far as they
will go. (See Picture opposite) The wheels should now be
locked. If the wheels move the brakes need adjusting.
Adjust the brakes by loosening the nut (arrowed) locking the
brake pad in place, then turn the pad so that it is near to, but not
touching, the tyre. Retighten the locking nut.
Always adjust both brakes at the same time and recheck that the
brakes work properly.
Note: Don’t leave the brakes ON for a long period. If you do a flat section may appear on
the tyre. When not using the wheelbase i.e. overnight or during storage, make sure the brakes
are OFF.

7.4 Replacing the gas struts.
The wheelbase is fitted with two gas struts one either side of the seat between the inner and
outer frame. A single lever located on the push handle and a cable linkage operates both gas
struts.
WARNING: - The gas struts are pressurised devices and therefore, are potentially
dangerous if mishandled. Do not attempt to dismantle or repair them. They
must always be replaced as a complete unit.
Important: - When removing or replacing the gas struts take care not to accidentally
operate the release lever in order to prevent the strut extending to its full
length. When fully open the gas strut length is longer than the fixing
centres and it is difficult to close them by hand.
7.4.1 Removal
1) Recline the seat to its mid position (See section 4.4).
2) Remove the operating cable from the strut by lifting it off the locating lug and fork. (see
pictures below).
3) Remove the lower mounting components using
13mm and17mm spanners. Make sure you take
note of the position of the components as you
remove them. (See sketch below).
