retainer for locking the new handlebar grip onto the wheelchair handlebar. With the allen key T bar,
unscrew the expander bolt so that the 4 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 (Fig 6). The control unit should now be in a vertical location (Fig 6). Repeat for the other
handlebar grip. NB To ensure a positive fitting, at least 7.5 cm (3 inches) of the wheelchair handlebar
must be covered by the new grip.
Care! Warning The correct fitting of the new handlebar grips and control unit is essential to the control of
the wheelchair and safety of the occupant. Please read these fitting instructions very carefully and if you
are in any doubt or require any assistance please contact your dealer or TGA.

14. If you require the wheelchair to be operated from the left hand side simply remove the backing plate at the
top of the handlebar, under the plate are two bolts which hold the control to the handlebar grip. Remove
the control and re-fit to the left hand grip with the allen key T bar provided.
15. Connect the plug into the socket at the base of the handlebar control. Ensure that it connects positively
(Fig 5E).
16. Connect the battery plug and socket to the plug and socket from the controller. This can only be done one
way, red to red and black to black (Fig 7).
17. Take the loop at the top of the lifting strap and place it over the left handlebar of the wheelchair. You will
note a two piece buckle in the strap. When the two parts of the buckle are fastened in the closed position
it will create a loop in the strap. Make sure the buckle is open and that the strap is just a straight length.
Now take the strap adjuster and alter as necessary the length of the strap by pulling it through the adjuster
until the wheel of the Powerpack sits firmly on the ground and the strap is just slack. Allow enough slack
so that the Powerpack has approximately one inch of downward movement, sufficient to cope with rough
terrain or potholes. To lift the Powerpack wheel clear of the ground, simply raise the Powerpack by pulling
up the strap below the buckle. Now fasten the two parts of the buckle together and this will hold the
Powerpack securely off the ground. To lower the Powerpack on to the ground, support the unit by holding
the lower part of the strap, release the buckle and gently lower the Powerpack. Always ensure that the
strap does not foul any moving components and that it is always attached to the handlebar.
