1.1 Introduction
1.1.1 Responsibility declaration
In spite of the great care we have taken there may be errors in this publication.
The author cannot be made liable for incorrect or missing information.
GGP SE reserves the right to regularly change product specifications without prior notice.
All the information in this book is based on the information available at the time of
production. Illustrations and photographs may be arranged schematically, which implies
that one picture may cover several models and therefore not correspond exactly with all
models.
1.1.2 How this manual is used
To make this manual easy to understand we have divided the machine into its main
systems and components. These parts are now the different chapters in the book.
Each chapter is divided up into sections.
There is a quick-guide on the cover of this book, which refers to the different chapters. In
each chapter there is a detailed table of contents so that you can easily and quickly find
what you are looking for.
For example, if you are looking for information on the Accessory Lifter you will find this in
chapter 3, Chassis and Body. On the first page in chapter 3 there is a detailed table of
contents which refers to the correct section, in this case section 3.1.
Always check that you are reading the right chapter for your particular machine before
starting the repair work.
1.1.3 Abbreviations
The following abbreviations are used in this manual:
HST Hydrostatic Transmission PTO Power Take Off
1.2 Safety Precautions
This manual has been written primarily for trained mechanics working in a well-equipped
workshop. Nevertheless, the manual contains such detailed information that it can also be
of use to owners who wish to carry out simple service and repairs on their machine.
A basic knowledge of repairs, tools and repair instructions is, however, always a
prerequisite for first-rate results.
A qualified mechanic should always be consulted if the owner does not have sufficient
knowledge to carry out repairs.
During the warranty period all service must be carried out by an Authorised Workshop for
the warranty to be valid.
The following basic points should be observed if the machine is to function perfectly:
• Follow the service schedule.
• Be on the alert for sudden vibrations or abnormal noise to avoid major breakdowns.
• Always use Genuine Spare Parts
• Follow the descriptions in this manual carefully. Do not take any short cuts.

1.4 Unpacking and assembly
Every Stiga Park has undergone an extensive
control programme before delivery. The
machines are delivered as completely
assembled as possible.
Thanksto this theassembly ondelivery is rapid
and easy.
The correct and careful assembly of the
machineondeliveryisasimplewayofensuring
satisfied customers!
Note!
The machine shall remain placed on the
pallet during the unpacking and
assembly.
1.4.1 Unpacking
Open up the crate and release the part as
follows:
1. Check the air pressure in the tyres. The
pressure is designated on the floor mat.
The air pressure in the tyres is of critical
importance for the performance and
handling of the machine. The correct air
pressure for mowing is 0.6 bar (9 psi) in the
front tyres, and 0.4 bar (6 psi) in the rear
tyres.
When using heavy accessories, e.g. snow
thrower, it may be necessary to increase the
pressure somewhat. However, the
maximum permitted pressure is always
0.8 bar (12 psi).
Too high pressure in the tyres leads to that
the machine drives poor due to:
• A small surface in contact to the ground.
• Hard tyre = less flexibility = self cleaning char-
acteristic deteriorate.
2. Remove the following parts from the
package and put them on the floor.
• The battery (some models).
• The steering wheel.
• The plastic bag, containing owners manuals,
information video and assembly screws.
Too high pressure Correct pressure
