3.1 CRITERIA FOR MAINTENANCE
The Instruction Handbook has a number of operations to be carried out by the Customer for a minimum of
basic maintenance, and other operations not always within his capacity.
For 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 any illegible or missing labels
–Check the tyre pressure
–Clean air filter
–Check engine oil level
–Check for fuel leaks
–Align the cutting deck
–Sharpen and balance the blade
–Check the wear of the drive belt
–Check the blade brake and engagement
–Grease the joint pins of the front wheels
–Check and tighten the engine screws
–Check all those items indicated in the engine manual
b) Routine maintenance
–All work carried out in point a), plus:
–Check the battery charger (➤ in electric start models)
–Check the drive belt tension
–Adjust the drive engagement
–Adjust the brake
–Adjust the blade engagement
–Adjust the blade brake
–Replace the front wheel bushes
–General lubrication
–Clean away grass cuttings and wash the exterior
–Clean and wash the inside of the cutting deck and collector channel
–Clean and wash the grass-catcher
–Touch up any damaged paint

4.1 ENGAGEMENT AND BLADE BRAKE
ADJUSTMENT
The blade receives movement directly from the
engine when the clutch is engaged. The motor is
connected via a lever-controlled cable.
➤In the case of a Tecumseh engine, blade
engagement is only possible by keeping the spe-
cific pedal pressed. 
On disengaging the motor, a brake should stop
the blade almost immediately.
After using it for a certain period of time, you may
need to adjust the engagement point of the clutch
in relation to the control lever.
A) Engagement system check
Check that the control lever (1), in the rest position
(blade disengaged), shows a certain mobility.

Remove the blade [see 4.7].
The blade engagement adjustment must be done
with the blade engaged.
Remove the guard 
(2)fixed by 5 screws (3).
Work suitably on the cable engagement register 
(4)
until the spring (7)length of 140.5-141.5 mm, mea-
sured on the outside of the eyelets, is obtained.
With this adjustment, the clutch lever 
(8)can cover
the whole stroke needed to obtain regular engage-
ment and disengagement.
A considerable increase in blade braking time can
be caused by wear or damage to the clutch friction
elements, which should therefore be replaced as a
block or limited to one of the two main elements
[see 6.4].

Refit the blade [see 4.7] by tightening the nuts to
the prescribed values.

							B) Check pedal operation (➤only with a Tecum-
seh engine)
If a delay in blade disengagement occurs, the con-
dition of the pedal group components must be
checked.

Remove the wheel cover [see 5.1].
Check that the roller 
(9)and runner (10)are not
worn and that the rod 
(11)is not distorted.
Check that the two clevis pins 
(12)and (13)permit
the regular and complete stroke of the lever 
(14)
and pedal (15). 

Refit the wheel cover [see 5.1].

Check correct blade engagement and brake
[see 4.1.A].

WORKSHOP MANUAL
page from 
2003to  ••••
4.2 BRAKE ADJUSTMENT
The machine’s reduced braking capacity is re-
gained by regulating the control cable’s adjuster.

Remove the collector channel [see 5.2].
Only make the adjustment when the parking brake
is engaged.
Remove the engine housing 
(1)and unscrew the
adjuster 
(2).
Through the rear outlet, lift the brake lever 
(3)with
one hand until the lever is blocked by the pads that
touch the brake disc.
Keep the lever 
(3)raised and regulate the adjuster
(2) until the control cable (4)is taut.
Release the lever 
(3)and loosen the front nut of the
adjuster 
(2)with three complete turns, in order to
lower the lever 
(3)and move the pads away from
the disc.
Tighten the adjuster 
(2)in this position and check
that the wheels are not in braking mode.
If braking is still poor or irregular after adjustment,
check that the brake pads and disc are not dam-
aged or worn to the point that they need replacing
[see 6.10 and 6.11 C].
When the adjustments have been made, the park-
ing brake should prevent the machine from moving
on a slope of 30% (16°) with the driver in position.

Remove the collector channel [see 5.2].

3/2002
4.3 DRIVE ENGAGEMENT ADJUSTMENT
If the forward drive fails to work properly after a
long period of use or after replacing the belt, this
may be caused by a change in the length of the
belt.
–A loose belt reduces output from the transmis-
sion and limits forward movement power;
–A belt that is too tight increases noise and
results in jerky movements or tipping up when
engaging the drive..
In these cases the stretcher will need to be adjust-
ed.

Remove the collector channel [see 5.2].
The adjustment must be made with the parking
brake disengaged and the cutting deck in position
«3».
Check that the engagement cable cap 
(1)(near the
pedal) is securely engaged in its housing and adjust
the nuts 
(2)until the spring length (3)is 174 - 176
mm, measured on the outside of the eyelets.
After adjustment, check that the engagement cable
spring 
(4)is not too taut or too loose and allows
enough play. Otherwise, turn the adjusting nut 
(5)
until you obtain the right conditions previously
described.
Finally, check the length of the spring 
(3)again.

Remove the collector channel [see 5.2].

							4.4 CUTTING DECK ALIGNMENT
The cutting deck descent is controlled by a lever
and guided by two connecting-rods at the front
and one at the back, all connected by another rod. 
For a good cut, it is essential that the cutting 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 of the parallel and the
minimum height front and back
b)adjustment of the parallel across the cutting
deck
Check the tyre pressures.  
If one or more tyres have been replaced and there
are found to be differences in diameter, 
do not
attempt to compensate these differences by giv-
ing different tyre pressures
, but make the adjust-
ments as in points “
A” and “B”.
A)  Combined adjustment of the parallel and the
minimum height front and back
With the machine resting on a flat, stable surface
(e.g. on a work bench), put blocks under the cutting
deck:
–at the front  26 mm 
(1)# code 60700000/0
–at the rear  32 mm 
(2)# code 60700001/0
Move the cutting height adjustment lever to position
«1» by engaging it in its notch.
Loosen the nuts 
(3-5) and locknuts(4-6)on the
right and left, as well as nuts 
(7-8), so that the plate
rests firmly on the blocks when all the fastenings
are loosened.
Fully tighten the nut 
(3)and locknut (4)and adjust
the nut 
(7)until the front part of the deck starts to
rise.
Adjust the nut
(5)until the rear part of the deck
starts to rise and fully tighten the locknut.
Check the front, and if necessary, adjust the nut
(7)
and fully tighten nut(8)on the pin (9).
B) Adjustment of the parallel across the cutting
deck
A difference in height from the ground between the left
and right sides of the deck can be compensated by
adjusting the nut 
(3)and the locknut (4)at the front left
coupling point.
NOTE
Remember to tighten all the nuts and locknuts once
these adjustments have been made, allowing the pins
to rotate freely [see 2.5.B].

STEERING GEOMETRY ADJUSTMENT





1 / 1
WORKSHOP MANUAL
page from

3/2002
4.5 STEERING GEOMETRY ADJUSTMENT
The correct steering geometry is given by the cen-
tre distance of the tie-rod connecting the stub
axles and centre distance of the control tie-rod.
Any faults caused by knocks or accidents result in
reduced driving precision and increased wear on
the tyres. These can be overcome as follows:
–uneven or excessive wear on the front tyres =
toe-in check,
–the machine does not maintain a straight line
when the steering wheel is straight = adjust-
ment of tie-rod.
A) Toe-in check
The exact toe-in is determined by the value of the
centre distance of the connecting tie-rod 
(1)(378
mm) [see 8.2.5].
If values are over the indicated tolerance limits,
check that the stub axles 
(2)are intact and replace
the tie-rod.
B) Adjusting the steering wheel position
Firstly check the toe-in (point “A”) and align the
front wheels.
If the steering wheel is not straight, loosen both the
nut 
(3)and the locknut (4), then tighten or unscrew
the joint 
(5)on the rod (6)until the steering wheel is
aligned.
When the adjustment is completed, fully tighten the
nut 
(3)and locknut(4).

4.6 BLADE ALIGNMENT CHECK
Excessive vibration when cutting and an uneven
cut can be due to misalignment of the blade
resulting from accidental knocks, or deformation
of the bracket.

Position the machine vertically [see 2.4].
Always wear strong gloves when handling the
blade.
Disengage the blade, place a straight metal rod(1)
on a point around the edge of the deck (2), turn the
blade by hand and check the distance between the
rod and the two ends “
A” and “B”. The distance
should be the same, and any difference should not
exceed 2 - 3 mm.
If you note higher values, check that the blade is not
deformed. If it is intact, check and if necessary
replace the bracket mounted on the clutch [see 6.4].
IMPORTANT!
Always replace a damaged blade and do not
attempt to repair or straighten it. Always use the
manufacturer’s genuine spare parts!

SHARPENING AND BALANCING THE BLADE





1 / 1
WORKSHOP MANUAL
page from 
2002to  ••••
4.7 SHARPENING AND BALANCING THE
BLADE
A badly sharpened blade causes grass to
become yellow and reduces the efficiency of the
grass collection. If not balanced, excessive vibra-
tion can be caused during use.
Always wear protective gloves when handling
the blade and protect eyes when sharpening.
To dismantle the blade (1), hold it firmly and undo
the two nuts
(2) of the screws.
A) Sharpening
Always sharpen both cutting edges of the blade (1)
using a medium grade grinder.
Sharpening must only be done from the rounded
side, removing as little material as possible. Make
sure that the cutting edge is parallel to the blade
axle.
The blade is to be replaced when the cutting edge
has worn down to 8 mm.
B) Balancing
Using the right tool, check the balance to make sure
that there is a maximum difference of 2 grams
between one side and the other.
When refitting the blades, follow the steps for fitting
the nuts and bolts and tighten the two nuts 
(2)
securely.
Since the nuts and bolts have specific characteris-
tics, replace them with only original spare parts.
