							ADJUSTMENT TO BLADE ENGAGEMENT AND BRAKE
If there seem to be problems in engaging the
blade or the time for stopping after disen-
gagement is over 5 seconds, adjust the
spring tension (1). 
To make this adjustment, 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), with the blade engaged and the cutting height adjustment
lever at position “1”. When the adjustment has been made, screw the nuts (2)
back on.
For  hydrostatic drive models:
A
DJUSTING THE SPEED CHANGE LEVER
The speed change lever has a clutch device which
keeps it in the position selected during forward
movement and which returns the lever to neutral
when brake is operated.
If the lever does not stay in position during working
and has difficulty in returning to neutral, the adjuster
nut (1) will need to be registered to restore normal
functioning.
S
HARPENING THE BLADE
Check that the blade is sharpened properly and firmly fixed to the bracket.
– A badly sharpened blade pulls at the grass and causes the lawn to turn yellow.
– A loose blade causes unusual vibrations and can be dangerous.
All operations on the blade (dismantling, sharpening,
balancing, remounting and/or replacing) require a certain familiarity and
special tools. For safety reasons, go to a specialized centre if you do not
have the right tools or experience.

							To remove the blade, hold it firmly wearing
strong gloves and undo the central screw
(1).
Sharpen the two cutting edges using a
medium grade grinding wheel and check
the balance by holding the blade up with a
round 18 mm diameter bar inserted in the
central hole.
To ensure that it works properly without
unusual vibrations any imbalance
between the two parts of the blade must
be below one gram.
This can be easily ascertained by putting
a one gram weight on the lightest end of
the blade. If it tends to go below the bal-
anced position it means that the balance
is correct, while if it stays up then the
other end will have to be made lighter.
A damaged or bent
blade must always be replaced;
never try to repair it! ALWAYS USE
MANUFACTURERS GENUINE
SPARE BLADES  !
When re-fitting the
blade, always follow the indicated
sequence, making sure that the
blade’s wings are facing towards the
interior of the cutting deck and that
the concave part of the cup spring
(1) is pressing against the blade.
Tighten the fixing screw (2) using a
torque wrench set to 45-50 Nm. If the
shaft hub (3) came off when disman-
tling the blade, make sure that the
key (4) is firmly in its right position.

							LAYING ON ITS SIDE
In order to easily reach beneath the
machine, it can be turned onto its side
after having removed the grass-catcher
and completely emptied the fuel tank.
Having put the machine onto a firm and
flat surface, engage the parking brake,
put the cutting deck into position «7»,
firmly grip the steering wheel and the
seat, and turn the machine onto its right
hand side so that it rests on the grass-
catcher (as shown), taking care not to
damage plastic parts.
Make sure that the
machine is stable before starting any
work and do not carry out work that
may cause it to fall.

8. ACCESSORIES ON REQUEST
1. FRONT COUNTERWEIGHTS
These improve stability at the front of the machine,
particularly when being used on ground which is
mostly sloping. 
2. STONE-GUARD KIT
For use in place of the grass-catcher when the
cuttings are not to be collected.
3. “CB01” MAINTENANCE BATTERY-CHARGER
This makes it possible to keep the battery in good
working order when the machine is in storage,
guaranteeing an optimum level of charge and a
longer life to the battery.
4. KIT FOR “MULCHING”
It finely chops the grass cuttings and leaves them
on the lawn, instead of collecting them in the
grass-catcher
