SUMMARY OF THE MAIN CONDITIONS WHEREBY THE SAFETY DEVICES PERMIT OR STOP WORK

–by preventing the engine from starting if all the safety requirements have not
been met;
–stopping the engine if even just one of the safety requirements is lacking.
a)To start the engine it will be necessary that:
–the transmission is in “neutral”;
–the blade is not engaged;
–the operator is seated or the parking brake is engaged.
b)The engine stops when:
–the operator leaves his seat when...

EN 27 HOW TO  USE THE  MACHINE

should be ascertained and dealt with to avoid re-activating the protection device.
To avoid activating the protection device:
–do not reverse the cables on the battery terminals;
–do not use the machine without its battery or damage may be caused to the
charging regulator;
–be careful to not cause short-circuits.

WASHING THE INSIDE OF THE CUTTING DECK
The machine has to be put on firm ground with the stone-guard or grass-catcher
in position. Washing the inside of the cutting deck and the collector channel is
done by attaching a water hose to the connector (1) and running water through
for a few minutes, with:
–the operator seated;
–the engine running;
–the drive in neutral;
–the blade engaged.
When washing, the cutting deck should be in the
fully lowered position. Take off the grass-catcher,
empty and rinse it,...

6. MAINTENANCE
Before cleaning, maintenance or repair work, take out
the ignition key and read the relevant instructions. Wear suitable clothing
and strong gloves.
Never get rid of used oil, fuel or other pollutants in unautho-
rised places!

BATTERY
To ensure long life to the battery it is essential to keep it carefully maintained.
The machine battery must always be charged:
–before using the machine for the first time after purchase;
–before leaving the machine for a prolonged period of disuse;
–before starting up the machine after a prolonged period of disuse.
–Carefully read and comply with the procedure for recharging described in the
booklet coming with the battery. If the procedure is not followed or the battery is
not charged,...

removed. When the problem has been resolved the system automatically
resets after a few seconds;
–a 6.3 A delayed fuse (1) for the protection of the general and power circuits of
the system. This must be replaced after having eliminated the fault.
When any of these devices are activated, the machine stops.
A blown fuse must always be replaced by one of the same
type and ampere rating, and never one of a different rating.
If you cannot find the cause of the protection devices activation, consult a...

CHANGING BELTS
The motion from the engine to the rear axle and from the motor to the blade is
obtained by two “V” belts, whose duration largely depends on how the machine is
used.
Replacing belts is quite complicated because of dismantling and adjustments and
must only be carried out by a Licensed Service Centre.
Belts must always be replaced as soon as they are seen to
be worn! ALWAYS USE MANUFACTURER’S GENUINE SPARE BELTS!
C
UTTING DECK ADJUSTMENT

to obtain...

–screw down the nut (5) on the rod until the right-hand front part of the deck
begins to rise, and then tighten the relative locknut (6);
–screw the nut (7) on the front left support until the deck in that area begins to
rise, and then tighten the nut (8)
If you are unable to get the cutting deck parallel, consult a Licensed Service Cen-
tre.
B
RAKE ADJUSTMENT
The adjustment will need to be made while
the parking brake is engaged.
Loosen the nut (1) which holds on the bracket
(2) and turn the nut (3)...

ADJUSTMENT TO BLADE ENGAGEMENT AND BRAKE
If there seem to be problems in engaging
the blade or the time for stopping after dis-
engagement is over 5 seconds, adjust the
spring tension (1).
To make this adjustment, loosen the nuts
(2) and screw or unscrew them on the con-
trol 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...
