6.3.4 REPLACING A FUSE

If a fuse is damaged the engine will immediately shut off, the mowing deck will stop and all
indicator lights on the dash board will turn off. In this case it is necessary to find the faulty
fuse and replace it with a new one. Under no circumstances should you replace a faulty fuse
with a fuse that has a higher current rating!
Fuses are accessible after removing the battery cover located under the steering wheel and
removing the fuse cover.
} Remove the fuse and insert a new fuse with the same rating as the initial fuse, i.e. 15A or
10A. If even after replacing the fuse the engine or the mowing deck will not work, contact
an authorised service centre.
} Certain machine models are equipped with a central switchboard. Under no condition
should you tamper with the switchboard! The only exception is the replacement of fuses.

6.3.5 LIFTING THE MACHINE

If you wish to lift the riding mower, use a jack and supports.
Proceed as follows:
} Place the jack underneath the gear box on the rear axle and lift the rear part of the machine.
} Insert two supports underneath the ends of the axles from the inner side of the rear wheels.
} Lift the front part of the machine and insert two supports under both ends of the front wheel axles.
Never lean the machine to the side where the carburettor is located. Oil could enter the air filter!

6.3.6 MOWING DECK - SHARPENING AND REPLACING BLADES

► SHARPENING THE BLADES

The mowing blades must be sharp, statically balanced and straight. Blunt, incorrectly sharpened or damaged mowing blades
cause grass to be torn out of the ground, damage to lawns and mediocre collection of mowed grass in the grass catcher.
Do not repair a blade that is deformed or otherwise damaged, replace it immediately.
Whenever handling the mowing blades, always use heavy-duty work gloves.
Sharpening procedure:
} Remove the grass catcher, tilt the machine on to the right side and prop it up using suitable supports. It is
recommended to invite another person to help with tilting the machine in order to prevent damaging a part of the
machine or an injury.
} Unscrew both blades and clean them.
} First sharpen with a grinder and then with a file.
6.3.6a
} On the 110 cm three-blade mowing deck each pair of blades is fastened using 3 bolts (blades are not equipped
with break pins). We recommend that you mark the blades before removing them to avoid problems when putting
them back.
Do not sharpen directly on the mowing deck.
} After sharpening the blades, do not install them yet, but check their balance, see procedure below.
} Prior to reinstalling the blades, check the condition of the break pins which serve as protection of the mowing deck.
If the break pins are damaged, replace them immediately. Spare pins are supplied with the machine.
} After checking the balance and the brake pins, screw the blades back in position. During installation, ensure that the bend of the
blades points upwards into the mowing deck body. Do not interchange the left and right blades. The right blade has a bolt with
a left thread.
} Carefully tighten the fastening bolts using a torque wrench using the prescribed tightening torque of
achieved the moment when the tangential (convex) spring under the fastening bolt is fully compressed and from this point on the
bolt is not tightened.

► BALANCING THE BLADES

Pay increased attention to levelling and balancing the blades. The vibration of blades that are not levelled and balanced may
damage the engine or the mowing deck.
When balancing, insert the screwdriver into the centring hole and set the blade into
a horizontal position. If the blade remains in this position, it is balanced. If one of the ends
is weighs down, grind this side until it is balanced. When balancing by grinding, do not
shorten the length of the blade! The permitted static imbalance may not exceed 2g.
