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.
STIGA 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.
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.
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.

1.2.1 Symbols and general
warnings
Warning!
This symbol indicates a risk of
personal injury or damage if the
instructions are not followed.
Note!
This text indicates a risk of damage to
the material or risk of unnecessarily
complicated work if the instructions
are not followed.
1.2.2 Warm parts
Please observe that engine and exhaust
system picks up a lot of heat during use.
This applies above all to the silencer of
machines equipped with catalytic
converter.
To avoid injuries, allow the machine to cool
before any kind of repairs are made to or
near parts of the engine or exhaust
system.
1.2.3 Moving parts
The machines are all equipped with v-belt
transmissions. Always stop the engine and
remove the starter key before inspections
or repairs are carried out.
Always use extreme caution when testing
systems with moving parts to avoid
injuries.
Always use Genuine Spare Parts during
service work.
1.2.4 Lifting and blocking up
Before work under the machine, always
make sure that lifting devices and jack-
stands are approved for the weight.
Work safe!
1.2.5 Cleanliness
Clean the machine before starting repairs.
Dirt that penetrates into sensitive
components can seriously influence the
service life of the machine.
1.2.6 Tightening torque
Unless otherwise stated the tightening
torque in the tables in the section
Technical specifications must be used for
the different sizes of screws. This does not
refer to self-tapping screws, which are
mainly used for the assembly of body
parts.
1.2.7 Sharp edges
Watch out for sharp edges, especially
when working with the mower deck. The
blades can be very sharp. Always wear
gloves when working with the blades.
1.2.8 Replacement parts
Always use Genuine Spare Parts during
service work.
1.2.9 Inspection
Each part dismantled in conjunction with
service work must be inspected.
Examine for: wear, cracks, out of
roundness, straightness, dents,
discolouring, abnormal noise and
jamming.

1.3 Unpacking and assembly
Every STIGA Park has undergone an extensive
control programme before delivery. The
machines are delivered as completely
assembled as possible.
Thanks to this the assembly on delivery is rapid
and easy.
The correct and careful assembly of the
machine on delivery is a simple way of ensuring
satisfied customers!
Note!
The machine shall remain placed on the
pallet during the unpacking and
assembly.
1.3.1 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 media and assembly screws.
Too high pressure Correct pressure

more than 12,5 during storage. If not, the
battery will be destroyed.
If the cables are disconnected/
connected in the wrong order,
there is a risk of a short-circuit
and damage to the battery.
If the cables are interchanged,
the generator and the battery
will be damaged.
The engine must never be driven
with the battery disconnected.
There is a risk of serious dam-
age to the generator and the
electrical system.

2.2 Lubrication chassis
The bearing for the articulation must be
lubricated in accordance with the service
schedule. Other moving parts are lubricated
once per season, although at least every 50
operating hours.
Note!
Lubrication is equally important for a
machine that is only used for a few hours
per year.
Note!
The lubricant provides not only
protection from wear but also from rust.
Note!
The machine should always be
lubricated before prolonged storage.
The bearing for the articulation has four grease
nipples which must be lubricated with universal
grease.
The steering chain must be lubricated with
chain spray two or three times per season.
If the chains are heavily fouled: dismantle the
chains and wash them.
Refit and lubricate them.
The pressure pin (A) in the seat suspension
must be lubricated to avoid problems with the
safety circuit.
Plastic bearings, e.g. the brake pedal bearing,
hydrogear pedal bearing and steering-column
bearing, must be lubricated with grease or
lubricating spray.
Drop a little engine oil or lubricating spray in the
ends of the control wires two or three times a
year.
Note!
Wires on machines used in
freezing conditions should not be
lubricated with engine oil since

fluent, strongly penetrating
lubricant, e.g. 5-56 or WD40.
