10. When using the Powerpack for the first
time, if the wheelchair pulls to the left or
right it is usually because the drive wheel
or wheels are not central. To remedy this,
simply adjust the Powerpack on the crossbar
as in Paragraph 9 until the wheelchair pulls
in a straight line. Similarly, if the mounting
brackets have not been fitted directly
opposite each other, this will also cause the
wheelchair to pull to one side or the other.
9. Place the battery in the tray with the
writing on the bag uppermost and the
handle towards you. The battery bag is
securely held in place by Velcro (Fig 4).

10. The next item to fit is the handlebar
control (Fig 5). This unit performs many
functions in addition to controlling the
motor.
Fig 5
11. The handlebar control can be fitted to
either the alternative mount bracket, which
fits to the standard wheelchair handle bar,
in front of the handgrip, or to the extended
handlebar grips supplied by TGA as an
additional kit.
12. If fitting the extended handlebar
grips, they replace the original wheelchair
handlebar grips as well as providing
extension handlebars for added comfort
when controlling the chair. If the handlebar
control is received fitted to the extension, it
is usually set for right-hand use but can be
reset for left-hand operation.
13. To fit the extended handlebar grips,
both handlebar grips need to be removed
from your wheelchair with care. Taking
each new handlebar grip in turn, remove
the rubber end caps and engage the long
4mm allen key T bar into the expander bolt
located approximately half way down the
inside of the new handlebar grip. Looking in
the other end of the handlebar grip, you will
see an expanding bolt, which is the retainer
for locking the new handlebar grip onto the
wheelchair handlebar. With the allen key
T bar, unscrew the expander bolt so that
the four expanding arms are unexpanded
and flush with the internal barrel (until
approximately a quarter of the bolt thread
is left in the internal barrel). You may need
to hold your finger on the barrel while this
is taking place to prevent it turning. Keep
the allen key T bar located in the expander
bolt, as this makes fitting easier and now
slide the new grip fitted with the control
onto the right-hand wheelchair handlebar
(Fig 5). The new grips are obviously longer
than the ones removed and this enables
the original handlebars to be extended.
This is sometimes useful when fitting the
Powerpack to give more clearance for
your feet. Now tighten the expander bolt
as much as you can using the long allen
key T bar. The control unit should now be
in a vertical location. Repeat for the other
handlebar grip. Please note: to ensure a
positive fitting, at least 7.5 cm (3 inches) of
the wheelchair handlebar must be covered
by the new grip.
