7) Balancing the wheelchair
The balance of the wheelchair can be adjusted by moving the rear wheels back or
forwards. The further forward you have the rear wheels the more ‘rear balance’ you
will have. This makes the chair lighter at the front and you have more weight on
the rear wheels.
It is important that you take time trying out a balance that suits your body and
driving techniques so that you adapt the chair to be as easy to drive as possible
without increasing the risk of tipping backwards. You should always have someone
standing behind you when you try out the chair after adjusting the balance. Anti-
tips eliminate the danger of tipping backwards. See the assembly instructions for
‘Anti-tips basket’.
8) Wheel base
This is a special adaptation. Generally you want the chair as long as possible but
if you wish to shorten your chair you can do as follows. The wheel base of the
wheelchair can be adjusted on an ungraded scale which means you can change the
distance between the casters and the rear wheels (to sit more compactly) by loose-
ning the clamps attaching the seat section to the chassis as shown in fi gure 2. You
should also loosen the clamps at the front by the footbar as shown in fi gure 4. You
can then push the seat forward or backwards to the desired position. Once you have
found a suitable position tighten the bolts. If you have shortened/lengthened your
chair by pushing the seat section back or forward, the balance of the chair will be
affected. You should therefore move the rear wheels to the same extent as you have
moved the seat to achieve the same balance as before.
You move the rear wheels as follows:
Remove the rear wheels.
Loosen the bolts on both sides of the chair that attach the clamps around the
chassis tubing.
You will now be able to push the camber axle forward or back along the hori-
zontal frame tubing. It is important that you have the clamps in the same for-
ward position on both sides of the chair. You can check this by measuring the
distance between the horizontal tubing at the rear and the back of the clamps,
making sure that the distance is the same on both sides.
Tighten the clamps around the camber axle. When you tighten the clamps you
should make sure that the axle protrudes to the same extent on both sides of
the chair.

Maintenance
Your Panthera is constructed to be virtually maintenance free. A few parts do re-
quire regular checking however.
Once a month you should:
Check the wheels and tighten the spokes.
Wipe the chair chassis over with car shampoo or washing-up liquid and a
damp cloth. If very dirty you can use a degreasing agent. Lubricate all movea-
ble parts with a universal lubricant (5-56, WD-40) after cleaning.
Clean the caster fork casing (between the wheel and the fork). Hair and dust
collect here which can damage the bearing. Loosen the nut using key no. 10
while holding the bolt with key no. 10. Remove the bolt and then the wheel.
Clean the washers between the wheel and the fork and wipe the outside of the
wheel bearing with a cloth. Drop some oil into each bearing. Reassemble the
parts.
Lubricate the rear wheel axles. Remove the wheel and distribute some drops of
oil over the axle.
Pump up the tyres. The tyres can be pumped by screwing the top off the valve
and fi lling with air using an appropriate valve adapter. The tyre can take 8 kg
of pressure.
Check that all the screws and nuts are securely fastened.
Check that the chair has not been damaged. If damage has occurred, contact us
immediately at Panthera Production AB.
Twice a year you should:
Lubricate the ball bearings for the brakes with some drops of oil.
Lubricate the bearings in the joints of the backrest. Remove the nut using cap
key no.10 and hold the bolt still with key no. 10. Lubricate the bearings with
some drops of oil.
Wash the seat upholstery, the back upholstery and the cushion cover in 40 de-
grees machine wash when necessary.
Guarantee and lifetime
The life of a Panthera depends on how much wear and tear it is exposed to and how
thorough you are with maintenance.
Guarantee: We offer a one year factory guarantee on the chassis.
Maximum weight: 33, 36, 39 and 42 cm 100 kilos.
