the electronics if for whatever reason an
overload occurs. At this point the motor will
shut down and you will have to switch the
key off, wait a few seconds and switch back
on to clear.
WARNING!
If this occurs the full weight of the chair
and its occupant will immediately be
transferred to the attendant until the
Powerpack resumes drive.
However, in order to carry on climbing
the gradient, a lot more effort will have to
be put into pushing in order to assist the
Powerpack and stop it shutting down again.
If the Powerpack does shut down more
than once, we would strongly recommend
that you find an alternative route as the
Powerpack will be trying to work outside its
design limitations and continual use may
cause damage.
14. The Powerpack is not designed to climb
steep gradients, nor to take you anywhere
under power assistance that you would not
normally be able to push the chair without
using powered assistance. It must be
remembered that even if the chair can be
powered uphill, you still have to get down
the other side which can sometimes be
even more difficult. We strongly recommend
the fitting of attendant controlled brakes
to your wheelchair if moderately steep or
long slopes are likely to be negotiated, the
wheelchair user is heavy or there are steep
pavement cambers to negotiate.
15. Range is dependent on various factors,
such as weight of occupant, number of
hills and the gradient of hills encountered
on your journey. In addition, how much
assistance the attendant gives to push the
wheelchair will affect the range. We strongly
recommend that initially, journey distances
are relatively short and are gradually
increased. This will allow the opportunity
to become used to the controls and get to
know the range provided by the battery on
your local terrain.
Note – The Powerpack should not be used
on gradients greater than the maximum
stated by the wheelchair manufacturer.

Fitting instructions

1. Remove the Powerpack and all associated
components from the packaging.
2. Both time and care must be taken
to ensure the Powerpack is set up in
accordance with these instructions and
fitted in the position that best suits the
particular chair it is being fitted to, both for
ease of use and safety.
3. Ideally the Powerpack should be
positioned so that the centre of the drive
wheel/s runs approximately in line with the
centre of the wheelchair rear wheels, Fig 1
A-A (single and twin wheel models). This
is not possible on some chairs, so it may
have to be positioned more towards the
rear but be aware that the further towards
the rear it is fitted, the greater chance of it
causing discomfort to the attendant whilst
walking. Fit it as far forward as possible,
but never fit forward of the wheelchair rear
wheels. The drive wheel (or wheels if a Duo)
should always be set to run in the centre
of the wheelchair (Fig 1 B-B). Twin wheel
models should have a wheel running equal
distance either side of the centre line of the
wheelchair (Fig 1 B-B).

4. Take the two mounting brackets and you
will see that one has a larger diameter shaft
than the other (Fig 2 C & D). Fit the larger
diameter right-hand mounting bracket to
the bottom of the wheelchair frame on the
right-hand side, as viewed from the rear. Fit
the smaller diameter left-hand bracket in
a corresponding position on the left-hand
side of the chair. Fig 1 demonstrates the
approximate positioning of the mounting
brackets on the chair (when viewed from
above). Do not tighten at this stage.
