The 80 A fuse is located in a fuse holder in the front section
of the battery case (see g. 28).
Open the cap of the safety holder and exchange the fuse.
Make sure that the fuse is pressed into the centre of the
spring contacts and that it is not at an angle. Close the cap
until you feel it snap back into place.

9.3 ChangingTyres
INFORMATION
Direct sunlight (UV light) causes the tyres to age prema-
turely. As a result, the tread surface hardens and corner
pieces break out of the tread.
INFORMATION
Whenever possible, avoid parking the wheelchair out-
doors. Regardless of wear and tear, the tyres should be
replaced every 2 years.When the wheelchair is not used
for extended periods of time, or if the tyres are heated
strongly (e. g. near radiators or by sunlight shining through
a window), permanent deformation of the tyres will result.
Therefore always make sure that the wheelchair has suf-
cient distance from sources of heat, move your wheel-
chair from time to time, or jack up the wheelchair when
storing it.
To change the tyre of a drive wheel, proceed as follows:
n Secure the wheelchair to prevent it from tilting to the side
by placing a suitable base under the drive unit support.
n To dismount a drive wheel, loosen the four Allen head
screws in the middle of the wheel (g. 29) with 8 mm
Allen wrench and remove the wheel.
