the following seat models:
•Driver’s seat MSG 65/511 (slender seat cushion and short back),
•Driver’s seat MSG 65/521 (wide seat cushion and short back),
•Driver’s seat MSG 65/522 (wide seat cushion and long back).
•Boat seat AVENTO-Evolution
•Boat seat AVENTO-Premium
The driver’s seat of the MSG 65/521 type forms the basis for illustration. In the case of technical deviations in the work steps,
(due to different seat models) refer to the current text or separate chapters of the manual.
Each chapter starts with a list of all preparatory work to be completed before starting repair. These preparations are described
in separate chapters and shall be carried out without the preparatory steps described there.
At the beginning of each description for repair you will find an overview diagram. All parts included in these overview diagrams
within one chapter are consecutively numbered starting with "1". Each component is referred to by the same number through-
out the document.
With the help of these overview diagrams an experienced technician will gain a quick overview.
For spare part orders please use the numbers stated in the latest issue of the relevant spare parts catalogue.

TABLE OF CONTENTS
The description of the work steps refers to the dismounted seat. Depending on the individual installation situation, some work
may also be performed while the seat remains installed. For this reason, check the environment of the installed seat for this
possibility before starting work. The safety notes of the specific vehicle manufacturers and those stated in Chapter 1.1 of this
repair manual must be strictly observed.
This repair manual also includes some information on optional extras, in case further explanation is required. Since the scope
of delivery depends on the specific customer order, the actual seat equipment may deviate from the descriptions and illustra-
tions in this manual. These deviations may be described in separate assembly instructions included in the scope of delivery of
the respective spare parts.
If not stated otherwise, the directional indications "front, back" and "right, left" refer to the installed seat regarded in forward
travel direction of the vehicle.
The document layout is suitable for later use of this repair manual via CD-ROM / INTERNET / INTRANET. For this reason a
navigation line has been added beneath the title. This navigation line includes some chapter titles and it allows the user to
jump directly to these chapters after the corresponding hyperlinks have been set.
Basic information about the seat
After removal, all parts must be cleaned and checked for their suitability for re-use. Defective parts and worn parts must be
replaced.
The company Grammer rejects any warranty claims, if damaged or worn parts and assemblies are not replaced by spare
parts released by Grammer.
