3.6.1 Replacing drive unit
• See fig. 020707020.
The drive unit should be replaced as follows:
• Support the wheelchair under the battery tray in such
a way that both drive wheels remain on the ground.
• Remove the cover from the battery tray. See
‘removing the covers’.
• Slide the protective cover (A) from the power module
(B) up, in order to gain access to the connectors.
• Pull the connector (C), from the connecting cable of
the relevant drive unit, off the power module.
• Cut through all cable-wrapping tape that is holding
this cable.
• Remove the side cover. See 'removing the covers'.
• Cut off the little tun (D) from the cable.
• Loosen the nipple (E) using a screwdriver.
After this, the inner cable (F) can be pulled away from
the neutral of the vacuum brake (G).
• Remove the drive wheel; see 'replacing drive wheel'.
• Loosen the bolts (H) with the washers, using an Allen key with a key width of 6 mm and stop the
locknuts (I) using a spanner with a key width of 13 mm.
• Hold securely to the drive unit (J) (support this if necessary) and carefully remove the three bolts with
their rings with which the drive unit is attached to the side frame.
• The drive unit can now be removed.
• Loosen the bolt (K) with the washers, using an Allen key with a key width of 6 mm and stop the locknut
using a spanner with a key width of 13 mm. Remove the sliding block (L).
The (new) drive unit can be placed in reverse order.
• Use new cable-wrapping tapes to fasten the connecting cable to the drive unit.
• After placing the drive unit remove the support.
• Adjust the cable of the neutral by turning the adjusting nipples (M) in such a way to make the neutral
operated correctly.
The wheelchair is ready to operate.
Attention:
• The locknuts may not be used again – use new ones when replacing.
