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 ve-

hicle),

– 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

☞ 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 8, 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.

Term deﬁnitions

Here you will ﬁnd explanations to the term used in

this manual:

Information to maintenance and ser-

vice work:

☞ Every wheelchair should undergo inspection

once a year.

– The inspection increases the safety and ex-

tends 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

maintenance and service.

☞ All screwed connections, if not otherwise not-

ed, tightened according to table Torque accord-

ing to DIN for screwed connections on page 36.

☞ The checklist of the annual inspection (for

checking oﬀ) should be used for copying.

– Checklists that have been completed

should be stored and a copy handed out

to the customer!
