5.2.1 Replacing Puma 20 motors

a lower voltage. This has a positive effect on maintaining the wheelchairs maximum driving speed which tends to diminish as
battery levels fall. Puma 20 motors delivered as spare part also have the new specifi cations. When replacing Puma 20 motors,
please note the following:
• New and old motors on the same wheelchair are not compatible. Replace both motors if the motor that needs replacement has
one of the following article numbers (the article number can be found on the ID plate): 9004277, 9004278, 9004279, 9004280,
9004281, 9004282, 9004283, 9004284
