7.9 Preventive mainte-
nance (annual serv-
ice)
For safety reasons and to prevent acci-
dents resulting from wear not detected
in time it is important that you have the
electric wheelchair serviced at annual
intervals.
Annual service intervals are required
under normal operating conditions.
Shorter intervals for brakes and chassis
checks are recommended in the case of
severe operating conditions, e.g. daily
driving on uphill/downhill gradients or
use by a nursing service - with frequent-
ly changing wheelchair users.
The following list of annual maintenance
work gives you a guide for carrying out
the maintenance work. It does not out-
line the actual scope of the necessary
work which can only be ascertained by
an inspection of the vehicle.
Have this work carried out by an author-
ised workshop in order to ensure that
the electric wheelchair offers the high-
est level of safety and reliability. The
employees of the workshop are familiar
with the technology of the vehicle and
have suitable tools. They can identify the
start of wear in good time and use only
original spare parts.
!
Attention:
The vehicle driver is responsible for
the correct functioning and safe con-
dition of the vehicle when driving on
public highways.
An incorrect or neglected cleaning and
maintenance results in a limitation of the
product liability.
– The wheel securing screws (Fig. 87/
➀
) ust be tightened after the drive
wheels have been mounted.
– The valve must protrude through the
valve opening to the outer side when
the hub cap is fitted.
7.8.2 Disassembling the swivel
wheels
The swivel wheel axle (Fig. 88/
➀
) must
be disassembled before the change or
repair.
☞
Note:
Make a note of the arrangement of
any used sleeves (Fig. 88/
➁
) and
washers to ensure a correct
assembly. The valve points outwards.
7.8.2.1 Tyre change
To change the wheel, first fully deflate
the tyre and then screw out the screws
at the outer edge of the rim (secured
with red caps, Fig. 88/
➁
). Now sepa-
rate the rim halves.
☞
Note:
Note that the tyre valve must point
to the outside during the wheel as-
sembly.
