If the symptoms persist when the tyre pressure has been corrected and
the nuts, bolts and screws have been tightened, consult your approved
INVACARE distributor.
For maintenance operations, consult your distributor who has all the
necessary information.
Twice a year, ask your distributor to inspect your wheelchair thoroughly
and carry out in depth maintenance. Regular maintenance allows
defective or worn parts to be identified and improves the normal operation
of your wheelchair.
The following table shows what to check when the wheelchair is
delivered, each week, each month and at 6 monthly intervals.
