Cleaning
Clean the wheelchair often. After use outdoors it should be cleaned even
more thoroughly. Use a damp cloth with a mild soap solution to wipe off dirt
and dust.
Once in a while remove the battery and chassis covers and clean them
thoroughly, wiping their undersides with a damp cloth.
NB! Do not hose down your wheelchair! The electronics may be damaged.
Wheels
Regularly check the wheels for the correct tyre pressure. Top up the air if
necessary. See page 53.
Check of brake release
Check regularly, approx. once per month, the brake release function by
engaging and disengaging the brake release a number of times.
Batteries
Storage
Note that a battery will run down of its own accord and a run-down battery will
be ruined if it freezes in cold weather. If the wheelchair is to be kept unused
for a lengthy period, the batteries must always be recharged once a month to
prevent damage.
NB! The temperature in the place of storage must not fall below 41 degrees f.
The Permobil Koala has maintenance-free gel-type batteries. This means there
is no need to check fluid levels.
Battery life depends entirely on regular charging.
