Fuses are located on the steering column and are accessible after lifting the hood and removing the
protective fuse cover.
Remove the fuse and insert a new fuse with the same rating as the initial fuse, i.e. 15A or 5A. 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 transmission 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 THE BLADES
Í 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.
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 30 ± 3 Nm. This torque is 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.
Í 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.
