Measuring the acid density
The measurement of the acid density
with the acid tester gives an insight
into the actual charge state of the bat-
teries.
!
Attention:
Observe the brochure <
Safety in-
formation electronic vehicles
>!
– Always open the sealing cap of only
one battery cell.
With the ball pump pressed, insert
the tube for sucking-in vertically,
from above, into the acid.
– Suck in the acid by slowly releas-
ing the ball (fig. 77).
– The floating indicator must swim
freely in the acid.
– Compare the acid level with the
charge scale of the float.
Charge the batteries immediately if
the acid level in the tube is lower than
the scale value of 1.18 kg/dm³. The
battery is fully charged if the acid lev-
el is above the scale value of 1.28 kg/
dm³.
The acid density difference between
the individual cell values should not
exceed 0.02 to 0.03 kg/dm³. If it does,
this can be due to battery damage.
Have the batteries checked by an au-
thorised workshop.

FUSES
Replacing the fuses
Before replacing fuses, park the wheel-
chair on a level surface and move the
selection lever to the drive mode po-
sition to prevent the wheelchair from
moving. Switch off the operating
module.
Always replace fuses with one of the
same type! New fuses can be obtained
at petrol stations.
☞
Note:
Have the fault corrected by your
dealer if the fuse blows again.
