CONTENTS
1. Rules and procedures for Service Centres
This chapter covers all the main aspects of the re -
lationship between the manufacturer and the ser -
vice centres.
A close collaboration between the manufacturer
and the service centres is conclusive for solving
pro blems in the most effective way as well as
maintaining an image of efficiency and reliability.
Compliance with these brief and simple guideli nes
will facilitate this task and prevent general mi -
sunderstandings 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 en-
vironment and respects the safety of both the
serviceman and the user of the apparatus.
3. Maintenance
This chapter deals with the criteria for routine
main ten ance.
4. Adjustments and tuning
This chapter deals with the adjustments to be ma -
de to remedy the more frequent performance fai -
lures and are usually resolved by quick checks and
tunings.
5. Removal of external parts and main
assemblies
For doing more difficult jobs, greater accessibility
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 mal-
functioning 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 procedure
can help you omit all those operations not con-
nected with the case in hand without, howe ver,
overlooking anything that may be necessary.
7. Electrical system
This chapter deals with the problems and checks
con nect ed 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 fa-
cilitate the pinpointing of any problems.
8. Technical specifications
This chapter summarises all the main information
re garding the machine.

MODE YEAR 2016
1.1 IDENTIFICATION AND PROCEDURES
A) Identification
1) Machine
Each machine has a label attached (1) under the dri -
ver’s seat which shows the technical specifications,
the model and the serial number.
The model and serial number must be shown on
e ach repair sheet when requests are made un der
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 manufacturer
to our precise technical specifications which differ-
entiate it from similar items by this same Manufac-
turer.
The serial number on the label (2) clearly identi-
fies the product and its specifications. This num-
ber must always be quoted when requesting spa -
re parts or any information from the Manu facturer.
3) Engine
The engine is made to precise technical specifications
which differentiate it from similar items by this sa me
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 Manufacturer.
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 manufacturers ap-
ply.
C) Service repairs after guarantee period
The Service Centre has to make out a report con-
taining the machine’s serial number, a summary of the
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 avail-
able 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 opportu-
nity for a careful inspection of the problem and the im-
plementation of corrective action at production level.
Similarly, the Manufacturer will notify of any faults dis-
covered on the machines produced, with recommenda-
tions for the most suitable procedures for their remedy.
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].

MODE YEAR 2016
2.1 SAFETY REGU ATIONS
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 regulations af-
ter reading through the procedures in this ma nual.
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 ma -
king appropriate checks every time there is the
chance to do so.
Particularly, every time there is work done on the
ma chine the Service Centre should:
1) check:
– that safety microswitches are working correc -
tly [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 sy -
stem).
2) they should also:
– restore to proper working order any safety de -
vi ces which have been manipulated or re mo -
ved;
– reattach inefficient, damaged or missing ca -
sings and protection covers;
– replace illegible labels;
– not endorse any repair or modification on the
machine or the engine which results in a chan -
ge in performance or use that is incorrect or dif -
ferent from the purpose for which it was de si -
gned 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 en tail
particularly hazardous situations besides the nor mal
hazard related to mechanical operations and that
can be avoided by taking the necessary care and at-
tention normally required for this type of work.
As well as following the usual accident prevention re -
gulations that apply to most repair shops, we re -
commend you:
– taking out the ignition key before beginning
any repair work.
– protect hands with suitable working gloves, e -
spe cially 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 environment
or where there are adequate exhaust fu me ex-
traction systems;
– do not pollute the environment with oil, petrol
or other waste and dispose of all waste in ac -
cor dance with the laws in force;
– ensure that other persons cannot accidentally
car ry out actions that may physically endanger
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 ut -
most care to avoid impairing the functionality and
safety of the lawnmower.
Operations that should be carried out with ut -
most care to avoid injury to operators.
“WARNING” stresses the risk of injury to oneself
and others if instructions and regulations are not
observed

2.4 P ACING THE MACHINE ON ITS SIDE
WARNING! Two people will be needed for this
work. When moving the machine onto its side it
should on ly be gripped at strong parts (steering
wheel, seat, frame, etc.) and NEVER by the plas-
tic parts of the body.
The fuel tank must be totally emptied before placing
the machine on its side.
Put the machine onto a flat and firm surface, re mo ve
the grass-catcher, engage the parking brake and
raise the cutting deck to its maximum height.
The machine must only be laid on its right hand side,
resting the seat (1) and one of the corners of the
grass-catcher (2) as shown. When doing this, firmly
grip the steering wheel and the seat and tip the ma-
chine over until it is resting on the grass-catcher, tak-
ing care not to dam age the body’s pla stic parts.
WARNING! Before carrying out any type of work
ma ke sure that the machine is completely stable,
and avoid operations that could cause it to fall
over.
WARNING! Be just as careful when putting the
ma chine back on a flat surface; two people are
needed for this operation..

2.5 OPENING THE WHEE COVER
The engine and the mechanical units can be rea ched
by turning back the wheel cover (1).
There are specific indications for opening the cover
which are shown below and also in the instruction
handbook.
Remove the grass-catcher or stoneguard and move
the machine to a flat floor. Raise the cutting deck to
its maximum height and place blocks (2) of about 65
– 70 mm beneath its edge in order to support the deck
during subsequent operations.
Put the drive re le ase lever in the «ENGAGED» posi-
tion. This is be cause the parking brake needs to be
disengaged to ensure the necessary movement to the
speed lever.
Unscrew the knob on the lever (3) and put it into po-
sition «R».
Open the access hatch (4) and unscrew the nut (5)
with a 13 mm spanner.
Release the lever (6) so that the deck rests on the
blocks, and keep it held to the side so that it does not
slip into any of the notches. Grip the base of the seat
(7) and turn back the cover.
When closing, make sure that the channel (8) is pro -
perly fitted onto the support (9) and resting on the
right-hand guide. Put the lever (3) into position «R»
and lower the cover (1) at the level of the levers (3)
and (6).
irst put the lever (6) into its housing, and then lever
(3), lower the cover until it centres on the fixing screw.
If this has been done correctly and the guide (9) is
pro per ly positioned, the opening of the channel will
ea sily slip into the hole in the plate (10) without any
need to guide it in manually.
If it does not enter easily and correctly,
Adjust the insertion [see 4.10].
ully tighten the nut (5), put the lever (6) in position
«7» engaging it in the stop notch,and remove the
blocks (2). Then refit the lever knob (3) and the hatch
(4).

2.6 PRACTICA HINTS
A) Fitting snap rings
One side of the “Benzing” snap rings (1) has a roun -
ded edge and the other a sharp edge.
or maximum grip the rounded part needs to be fa -
cing 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 va rious
directions.
A typical situation has the pin (3) fixed by a self-lock -
ing nut (4) with two anti-friction washers (5) in bet -
ween the pin (3) and the support element, and bet -
ween this and the nut (4).
Since these are joints, the nut must never be tighte -
ned completely but only so much that it can ensure
the free rotational movement of the pin on its axis wit -
hout, how ever, creating excessive free play which
could result in the parts concerned becoming mi -
saligned 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 di-
rection 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.

3.1 CRITERIA FOR MAINTENANCE
The Instruction Handbook has a number of operations to be carried out by the Customer for a minimum of ba -
sic maintenance, and other operations not always within his capacity.
or this reason the Service Centre should undertake to keep the machine in perfect working order in two ways:
a) Tuning the machine whenever possible.
b) Proposing a regular maintenance programme to the Customer to be carried out at prearranged intervals (for
example, at the end of the summer or prior to a long period of inactivity).
a) Occasional tuning
– Check working order of safety devices and renew illeg ible or missing labels
– Check tyre pressures
– Clean air filter
– Check engine oil level
– Check for fuel leaks

4.1 B ADE ENGAGEMENT ADJUSTMENT
The blade is run from the engine using a «V» belt
and is engaged by a stretcher worked from the le -
ver.
After a certain amount of use the belt can become
longer which can result in malfunctioning, i.e.:
– belt slipping = belt stretched
– difficulty in disengaging, with a stiff lever and the
blade continuing to run = belt shortened
In both cases the stretcher needs to be adjusted.
The length of the spring (1) must be adjusted with the
blade engaged and the cutting deck in position «1»,
because in other positions the length can vary con-
siderably.
Loosen the nuts (2) and screw or unscrew them on
the control rod (3) in order to obtain a distance of 77-
79 mm between the bracket (4) and the inside of the
washer (5).
When the adjustment has been made, screw the nuts
(2) back on.
When the blade engagement has been adjusted it is
al ways advisable to …
Check that the blade brake is working correctly
[see 4.2].

4.2 B ADE BRAKE ADJUSTMENT
The blade has a brake which stops rotation within
fi ve seconds:
– when the blade disengages
– when the operator gets out of the seat without di -
sengaging the blade.
Longer braking times do not comply with safety re -
gulations, but adjusting the brake so that it stops
quicker than this can cause the belt to slip on the
shoe resulting in overheating with the typical smell
of burnt rubber.
A) Adjustment of the brake after disengaging
the blade
The braking power on the blade belt is generated by
the spring (1) which catches the blade engagement
lever (2) after disengagement. In order to use all the
braking power, do not allow the lever to reach its end
of travel in relation to the guide shoe (3).
Check that the brake shoe (4) is not deformed.
Remove the steering column cover [see 5.1].
Disengage the blade and check that the lever (2) and
guide shoe (3) have a clearance of at least 7-8 mm.
If this is not so, adjust the nuts (5) on the tie-rod (6)
until you achieve this clearance.
Reassemly the steering column cover [see 5.1].
B) Adjustment of the brake after the operator
gets out of the seat (
➤ ➤
models with GGP
nd Hond GXV390 engine only)
Lift the wheels cover [see 2.5].
Remove the collector channel [see 5.5].
The braking force on the blade belt is generated by
the return spring on the seat, which acts on the bra -
ke shoe (4) via the cable (8) and the spring (9).
After making the adjustment indicated in point “A”,
regulate the adjuster (10) until the spring (9) is 48 - 49

After adjustment, disengaging the blade or getting out
of the seat, the brake shoe (4) should press a de -
quately against the belt (7) and stop rotation within 5
seconds of disengagement.

4.3 BRAKE ADJUSTMENT
educed braking power is corrected by adjusting
the spring on the brake rod which can be reached
af ter having lifted the wheels cover.
Lift the wheels cover [see 2.5].
The adjustment is to be made with the parking bra ke
engaged and consists of altering the length of the
spring to the best measurement. The braking ca -
pacity is increased by screwing the nut down on the
rod (and thus shortening the length of the spring).
➤ ➤
for Tuff Torq K46T drive models:
Turn the nut (10) so that the spring (11) is 45 - 47
mm long, measured from the inside of the wa -
shers. Never go under these amounts to avoid
overloading the brake unit.
NOTE
No further adjustments to the braking system are
re quired.
➤ ➤
for Hydro Ge r T2-BDBE-2X1A-16X1 drive
models:
Loosen the nut (21) and then turn the nut (22) so
that the length of the spring (23) is 34-36 mm mea-
sured from the inside of the washers.
Never go under these amounts to avoid overload-
ing the brake unit.
NOTE
No other adjustments to the brake system are re-
quired
When the adjustments have been made, the parking
brake should prevent the machine from moving on a
slo pe of 30% (16°) with the driver in position.
Close up the wheels cover [see 2.5].

4.4 DRIVE EVER ADJUSTMENT
This adjustment should be made every time work is
done on the drive lever unit or when the pedal
shaft, back axle or the lever return cable are di -
smantled.
The main indicators that it is not working properly
are:
– the lever does not return when the pedal is pres -
sed = cable loose,
– the lever does not go the full distance, reducing
per formance = cable too tight,
– the lever is stiff = the spring for the clutch device
is badly adjusted,
– the lever is too loose and, under pressure, does
not stay in position = the spring for the clutch de-
vice is badly adjusted or there is oil on the friction
disc,
– the machine has a tendency to move when the
le ver is in “neutral” = the connection rod is in cor -
rectly ad just ed.
A) Adjusting the “neutral” position
Remove the right-hand rear wheel [see 6.1].
Remove the collector channel [see 5.5].
The pedal position is to be adjusted starting with the
lever (1) or (1a) of the hydrostatic unit in the “neutral”
position.
➤ ➤
for Tuff Torq K46T drive models:
Keep the lever (1) in the “neutral” position; this po-
sition «N» can be easily recognised as it is forced
to stay there by a fastening sphere.
➤ ➤
for Hydro Ge r T2-BDBE-2X1A-16X1 drive
models:
Keep the lever (1a) in the “neutral” position; this «N»
position is achieved by fitting a 28 mm high block
under the protruding end of the screw (1b).
NOTE - The “neutral” position on a new drive unit,
or one overhauled by the Manufacturer, is given by
a spacer which must be removed after the unit
has been adjusted.
Ensure the wheel cover is closed and fitted securely
in place, now adjust the nuts (2) on the bar (3) until the
control lever (4) is centred on the central groove (5)
on the cover.

Check that the drive to the wheels engages only
when the control lever (4) is moved forwards or back -
wards.
Check that the probe of the microswitch (6) is in the
“pres sed” position on the tip of the cam (8). If it isn’t,
loosen the locknuts (7) and move the microswitch (6)
sufficiently so that by moving the control lever (4) the
click of the contact can be heard passing from the
“pressed” position to the “released” position.
Reattach the collector channel [see 5.5].
B) Adjusting the release rod of the clutch
device
With the brake pedal released, turn the nuts (9) until
there is a free play of 0.5 mm between the shoe (10)
and the release rod (11).
C) Adjusting the clutch device
When in motion, the lever is held in the selected po -
si tion by a clutch device which is made up of a sli ding
sector (12) between two friction discs (13), pres sed to-
gether by a spring (14).
The spring tension (14) is adjusted at the nut (15) un-
til a length of 18 mm is obtained with the pedal re-
leased.
Check that the friction discs (13) are in good condition
and with no traces of oil. Otherwise replace them
[see 6.10].
D) Adjusting the lever return cable
Lift the wheels cover [see 2.5].
With the control lever in the “neutral” position and the
pedal released.
Check the length of the spring (16) and regulate the
ad juster (17) until a length of 74 - 76 mm is obtained
mea sured from the outside of the eye-rings.

When this adjustment has been made, with the park-
ing brake engaged, there should be free play of
0.5 ÷ 1 mm between the lever (18) and the limit stop
(19).
Close up the wheels cover [see 2.5].
E) Adjusting the limit stop position
of the levers
If the stop hook has been dismantled or replaced, the
position of the terminal (20) will need to be ad justed
compared to the levers (21) and (22).
This must be a position which prevents the terminal
(20) from interfering with the swinging movement of
the lever (21) and blocking the lever (22) at the same
time.
Lift the wheels cover [see 2.5].
Put the control lever in “neutral” and engage the park -
ing brake.
With both nuts (24) loosened, close the two levers
(22) and (23) so that the terminal (20) is held be tween
them, push it back as far as possible and then tighten
the two screws (24).
Close up the wheels cover [see 2.5].

4.5 A IGNING THE CUTTING DECK
The cutting deck is lowered by a lever and is gui ded
by a connecting rod at the front and one at the
back right. A third connecting rod at the front left is
connected to the deck by an adjuster sy stem.
In order to get a good cut it is essential that the cut-
ting deck is parallel with the ground crosswise, and
slightly lower at the front.
Two adjustments can be made on the jointed sys-
tem of the cutting deck:
) a combined adjustment to the parallel and the
minimum height front and back
b) an adjustment to the parallel across the cutting
deck alone
Check the tyre pressures. If one or more tyres have
been replaced and there are found to be differences
in diam eter, do not attempt to compensate these
differences by giving different tyre pressures, but
make the adjustments as in points “A” and “B”.
A) The combined adjustment to the parallel
and the minimum height front and back
Put the machine onto a flat and stable surface (such
as a work bench) and put blocks beneath the cutting
deck:
– at the front 26 mm (1)
– at the rear 32 mm (2)
Put the cutting height adjustment lever into the notch
at position «1» and loosen the nuts (3 – 5 – 7) and the
locknuts (4 – 6 – 8) so that the deck rests firmly on the
blocks.
Screw down the nut (3) until the front part of the cut -
ting deck starts to rise, then tighten the relevant lock -
nut (4) in order to create a fixed reference point for the
following stages.
Turn the nut (5) so that it presses on the pin (9) and
cause s the rod (10) to move forward until all free
movement is eliminated and the front right of the
deck begins to rise.

Having checked that the rod has no possibility of longi tudi nal movement, tighten the locknut (6).
Screw down the nut (7) of the transverse adjuster until the front left begins to rise, and then tighten the locknut
(8).
B) Adjusting the parallel across the cutting deck alone
Any difference in height from the ground between the left and right sides of the deck can be compensated by
turn ing the nut (7) and the locknut (8) at the front left coupling point.
NOTE
Remember to tighten all the nuts and locknuts once these adjustments have been made, leaving the necessary
free rotation movement to the pins [see 2.6.B].
