CONTENTS
1. Rules and procedures for Service Centres 
This chapter covers all the main aspects of the
relationship between the manufacturer and the
service centres.
A close collaboration between the manufacturer
and the service centres is conclusive for solving
problems in the most effective way as well as
maintaining an image of efficiency and reliability.
Compliance with these brief and simple guide-
lines will facilitate this task and prevent general
misunderstandings and time-wasting for both
the manufacturer and the service centre.
2. General and safety regulations
This chapter covers the main aspects of a servic-
ing procedure and the general rules for guaran-
teeing a successful service which protects the
environment and respects the safety of both the
serviceman and the user of the apparatus.
3. Maintenance
This chapter deals with the criteria for routine
maintenance.
4. Adjustments and tuning
This chapter deals with the adjustments to be
made to remedy the more frequent performance
failures and are usually resolved by quick checks
and tunings.
5. Removal of external parts and main assem-
blies
For doing more difficult jobs, greater accessibili-
ty may be required. This can be done by taking
the unit concerned off and working at the bench,
or by removing the cover or other external parts.
Whether or not this will be useful is at the discre-
tion of the mechanic’s experience.
6. Repairs
This chapter deals with all the more complex
work connected with the replacement or repair
of malfunctioning or worn parts.
The descriptions must follow a logical sequence-
and can include operations not specifically con-
nected to a particular type of repair.
In this case, careful reading of the entire proce-
dure can help you omit all those operations not
connected with the case in hand without, how-
ever, overlooking anything that may be neces-
sary.
7. Electrical system
This chapter deals with the problems and checks
connected with the electrical system.
All work can be done using a tester without hav-
ing to use special equipment.
The electrical diagrams can be useful to you for
understanding how the system functions and to
facilitate the pinpointing of any problems.
8. Technical specifications
This chapter summarises all the main information
regarding the machine.

1.1 IDENTIFICATION AND PROCEDURES
A) Identification
1) Machine
Each machine has a label attached (1)under the
driver’s seat which shows the technical specifica-
tions, the model and the serial number.
The model and serial number must be shown on
each repair sheet when requests are made
under guarantee, and are indispensable for
spare part orders.
2) Transmission (Rear axle)
The transmission unit (both mechanical and hydro-
static) is made up of an engine block including the
rear axle. This unit is made by another manufactur-
er to our precise technical specifications which dif-
ferentiate it from similar items by this same Manu-
facturer.
The serial number on the label (2) clearly identi-
fies the product and its specifications. This num-
ber must always be quoted when requesting
spare parts or any information from the Manu-
facturer.
3) Engine
The engine is made to precise technical specifica-
tions which differentiate it from similar items by this
same Manufacturer.
The serial number on the label clearly identifies
the product and its specifications. This number
must always be quoted when requesting spare
parts or any information from the Manufactur-
er.A) Guarantee validity
B) Guarantee validity
The guarantee is supplied under the terms and the
limits of the contractual relations in being. As far as
the engine and the transmission unit are concerned,
the conditions given by their respective manufac-
turers apply.
C) Service repairs after guarantee period
The Service Centre has to make out a report con-
taining the machine’s serial number, a summary ofthe problem, the repairs carried out and any spare
parts used for each repair done on the machine.
A copy of this report must be retained to be made
available to the Manufacturer together with the parts in
case of any subsequent disputes with Customers.
D) Fault notification
The Manufacturer welcomes any notifications of faults
that recur with particular frequency. It gives the oppor-
tunity for a careful inspection of the problem and the
implementation of corrective action at production
level.
Similarly, the Manufacturer will notify of any faults dis-
covered on the machines produced, with recommen-
dations for the most suitable procedures for their rem-
edy.
E) Spare parts request
When requesting spare parts, the code number must
be given, referring to the exploded charts for the year
of manufacture, shown on the identification label [


point A].

2.1 SAFETY REGULATIONS
A) Qualification of operators
All maintenance, disassembly and repairs must be
carried out by expert mechanics who are familiar
with all the accident prevention and safety regula-
tions after reading through the procedures in this
manual.
B) Safety measures
All the machines are manufactured in accordance
with the strict European safety regulations in force.
To maintain these levels of safety in the longer term,
the Service Centres should work to this end by
making appropriate checks every time there is the
chance to do so.
Particularly, every time there is work done on the
machine the Service Centre should:
1) check:
–that safety microswitches are working cor-
rectly  [see 7.3];
–that the casings and protection covers have
not been removed;
–that the labels with instructions or provisions
have not been removed or have become illegi-
ble (these form an integral part of the safety
system).
2) they should also:
–restore to proper working order any safety
devices which have been manipulated or
removed;
–reattach inefficient, damaged or missing cas-
ings and protection covers;
–replace illegible labels;
–not endorse any repair or modification on the
machine or the engine which results in a
change in performance or use that is incorrect
or different from the purpose for which it was
designed and approved;
–warn the Customer that the failure to comply
with the above points results in the automatic
annulment of the Guarantee and the Manufac-
turer declines all responsibility, as also shown
in chapter 1 of the Instruction Booklet.
C) Precautions during servicing
The operations described in this manual do not
entail particularly hazardous situations besides thenormal hazard related to mechanical operations
and that can be avoided by taking the necessary
care and attention normally required for this type of
work.
As well as following the usual accident prevention
regulations that apply to most repair shops, we rec-
ommend you: 
–taking out the ignition key before beginning
any repair work.
–protect hands with suitable working gloves,
especially when working near the cutting unit; 
–check that you do not cause accidental petrol
leaks or other losses;
–do not smoke when working on the tank or
when handling petrol; 
–do not inhale oil or petrol fumes; 
–clean up all traces of spilt petrol immediately; 
–test the engine in a well-ventilated environ-
ment or where there are adequate exhaust
fume extraction systems;
–do not pollute the environment with oil, petrol
or other waste and dispose of all waste in
accordance with the laws in force;
–ensure that other persons cannot accidentally
carry out actions that may physically endan-
ger those working on the machine.
D) Necessary equipment
All the operations can be carried out with the tools
normally used in a good garage.
Some operations require special equipment and
tools [

2.2].
E) Symbols and terms used for safety purposes
Some paragraphs in this manual are preceded by
symbols which indicate the following:
Operations that should be carried out with
utmost care to avoid impairing the functionality
and safety of the lawnmower.
Operations that should be carried out with
utmost care to avoid injury to operators. 
“WARNING” stresses the risk of injury to oneself
and others if instructions and regulations are not
observed

							2.3 LIFTING
The machine must never be lifted using a hoist
or other lifting equipment which uses cables.
A) Front
ONCE THE PARKING BRAKE HAS BEEN
ENGAGED, the lawn-tractor can be lifted using a
jack which pushes on the underside of the frame,
placing a wood block 
(1)between the base of the
jack and the frame and checking to see that the free
movement of the front spring equaliser has not
been obstructed.
B) Rear
Place a suitable block (2)beneath the lower edge of
the plate.
In any case, an appropriately sized wedge
(3)
should be placed behind the opposite wheels to
stop the lawn-tractor from accidentally moving
backwards.

2.4 VERTICAL POSITIONING
WARNING! Two people will be needed for this
operation. When lifting and tipping backwards,
only solid parts should be gripped (steering
wheel, frame, rear plate, etc.) and NEVER parts
of the bodywork in plastic.
The tank must be checked before putting the lawn-
tractor in a vertical position to make sure that there
is no more than 2 litres of fuel inside.
To assure full stability, the lawn-tractor must only be
rested on the points shown, inserting a block 
(1)of
about 120 mm under the lower edge of the plate
and taking care not to damage the parts in plastic
and the grass-catcher mounts 
(2).
WARNING! Before carrying out any type of work
make sure that the machine is completely sta-
ble, and avoid operations that could cause it to
fall over.
WARNING! Be just as careful when putting the
machine back on a flat surface; two people are
needed for this operation.

							2.5 PRACTICAL HINTS
A) Fitting snap rings
One side of the “Benzing” snap rings (1)has a
rounded edge and the other a sharp edge.
For maximum grip the rounded part needs to be
facing towards the element to be held 
(2), with the
sharp edges on the outside.
B) Joint pivot pins
There are a large number of pivot pins, usually con-
nected to rods, that need to be able to move in var-
ious directions.
A typical situation has the pin 
(3) fixed by a self-
locking nut 
(4) with two anti-friction washers (5)in
between the pin 
(3)and the support element, and
between this and the nut (
4).
Since these are joints, the nut must never be tight-
ened completely but only so much that it can
ensure the free rotational movement of the pin on its
axis without, however, creating excessive free play
which could result in the parts concerned becoming
misaligned and failing to work correctly.
C) Crown fasteners
Some pin ends (6)are secured by crown fasteners
(7). During dismantling, these fasteners are always
damaged and lose their hold, 
so they should never
be reused
.
On assembly, make sure it is inserted in the right
direction and push the fastener 
(7)onto the pin
using a pipe or socket spanner 
(8)with the right
diameter, so that it can be fitted without deforming
the fastener “crown”.
A deformed fastener should always be replaced.
