GENERAL
Foreword
This maintenance and service manual is intended
for the specialist dealer and describes all adapta-
tions and adjustments as well as the required ser-
vice, maintenance, repair and replacement jobs.
☞This maintenance and service manual is sup-
plemented by the following documents:
the model dependent operating manual
(an operating manual is supplied with each vehicle),
the model dependent operating manual < Operat-
ing module >,
(an operating manual is supplied with each vehicle),
the safety and general handling instructions < Elec-
tronic vehicles >,
the model dependent spare parts list,
(the required spare parts list can be obtained
through the specialist dealer access on our
website).
All required documents as well as additional infor-
mation to our products are located on our website
under:
< www.meyra.com >.
Requirements concerning workshop
personnel
Special knowledge is required to carry out the
maintenance and service work described in this
maintenance and service manual and may there-
fore only be carried out by educated qualified per-
sonnel.
☞We therefore offer vehicle specific courses that
provide the specialised personnel with the re-
quired qualification.
!
Attention:
During all corresponding work there is always a
danger of jamming or skin abrasions!
.Knowledge of this maintenance and service
manual as well as the supplementing docu-
ments (view chapter foreword) is mandatory
for the correct and safe execution of the work
required on the wheelchair.
☞The document, especially the chapter Safety
information on page 13, must therefore be
read carefully and observed by all persons, that
are assigned to work on the wheelchair.
Customer support
Technical questions will gladly be answered by
your national Meyra distribution partner.

Working on the vehicle
☞For maintenance and repairs the vehicle is to
be switched off and secured against uninten-
tionally rolling away.
☞Additionally the main-/battery fuse is to be re-
moved.
☞Before working on electric parts, the plugged
connection from the battery cable to the pow-
er module might also need to be disconnect-
ed.
☞Before working on electric adjustment the cor-
responding plug of the connection cable is to
be pulled.
Information to maintenance and ser-
vice work:
☞Every wheelchair should undergo inspection
once a year.
The inspection increases the safety and extends
the life span of the wheelchair.
☞For highly strained wheelchairs for example in
case of:
extreme strain,
user still growing,
users with changing disease patterns,
it is recommended to have the wheelchair
checked, maintained and if required adjusted
semi-annually.
Only original spare parts are to be used for all main-
tenance and service.
☞Before beginning with the service work check
the general condition of the wheelchair.
☞All screwed connections, if not otherwise not-
ed, tightened according to table Torque accord-
ing to DIN for screwed connections on page 98.
☞The maintenance schedule (Checklist) should
serve as a master for copying.
Maintenance schedules that have been filled
out are to be kept on file and a copy handed to
the customer!

Typ)
2. The serial number (beside the field SN)
TERM DEFINITIONS
Here you will find explanations to the term used in
this manual:
Service position
The service position [2] describes a vehicle with
corresponding seat position in order to enable e. g.
unencumbered maintenance jobs.
☞Access to electronic modules might require
prior pulling out of the battery box as well as
removing the rear revetment or battery cover
[3] and removing the leg supports.

Depth adjustment of the footboard
The depth adjustment of the footboard is done by reposi-
tioning the removable distancer pieces (3).
Lift the loose side of the footboard slightly.
Reposition the desired amount of distancer pieces on the
lifted side.
Pull/press the distancers that are to be repositioned on the
right side of the footboard outward from the retaining
rod [4].
☞Note:
In certain angle settings of the footboard it is possible
that a removal or placing of certain distancer pieces is
not possible. Then fold up the footboard.
