Take off the spark plug cable and remove the spark plug using a wrench key.
Visually inspect the exterior appearance of the spark plug. If the spark plug is visibly significantly
worn out or if the insulator is cracked or it is peeling, it is necessary to replace it.
If the spark plug is soiled or only slightly worn, it is necessary to carefully clean it with a suitable
wire brush (copper).
Using a gauge measure set the distance of the electrodes (
After performing maintenance on or replacing the spark plug, pull it tight in position. An incorrectly
tightened spark plug heats up significantly and may cause serious damage to the engine.
Check, maintain and replace spark plugs according to the instructions contained in the user's manual for the engine
supplied by its manufacturer.
REPLACEMENT OF THE FUEL FILTER
Never allow the engine to run without an air filter. This rapidly wears out the engine.
Replace the fuel filter according to the instructions contained in the user's manual for the engine supplied by its
manufacturer.
6.3.3 REPLACING LIGHT BULBS
The lights are mounted inside the hood and are accessible after lifting the hood. In the event that they need replacing, consult the
correct type of light with your supplier or the mower manufacturer based on the model of your mower.
For replacement, disconnect the connector (1) of the light, with one hand hold the light from the outer side of the hood
(so that it does not fall on the ground) and use the other hand to slide out the bulb socket (2). Then take out the light

(3) through the hood. For installation proceed in the reverse sequence.
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 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 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 MOWER
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 mower to the side where the carburettor is located. Oil could enter the air filter!
6.3.6 MOWING DECK - SHARPENING AND REPLACING THE 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.
