6.3.4 REPLACING FUSES

If a fuse fails, the engine will immediately quit, the mowing mechanism will stop, and all gauges on the
instrument panel will go dark. In that case, it is necessary to seek out the blown fuse and replace it with
a new one. Never replace a faulty fuse with one of a higher current rating!
The fuses are located on the steering column and can be accessed by lifting the cover and removing the
protective fuse cover.
Remove the fuse and insert a new fuse of the same rating as the original one, i.e., 15A or 5A. If the

engine or the mowing mechanism cannot be started after fuse replacement, contact your authorized
service centre.
Some models of machines are equipped with a central electrical installation distribution box. Never

tamper with this distribution box, except to change fuses.
6.3.5. RAISING THE MACHINE
If you want to raise the lawn mower, use a jack and supports.
Proceed as follows:
Place the jack under the transmission on the rear axle and raise the machine's rear end.

Insert two supports under the ends of the axle inside the rear wheels.

Lift the front end of the machine and insert two supports under each end of the front wheel pins.

Never tilt the machine to the side where the engine's carburettor is located. This could make
oil seep into the air filter!

6.3.6 MOWING MECHANISM - SHARPENING AND CHANGING BLADES

 SHARPENING BLADES

The cutting blades must be sharp, statically balanced and straight. Blunt, improperly sharpened or
damaged blades uproot grass, damage the lawn and don't allow the catcher to collect grass properly.
- Never repair a deformed or otherwise damaged blade. Always replace it
immediately.
- Whenever handling the blades, wear solid work gloves.
Sharpening process:
Remove the grass catcher, tilt the machine to the right side, and place appropriate pads

under it. We recommend having another person help, in order to avoid injury and damage
to the machine.
Unbolt both blades and clean them.

First sharpen the blades with a grinder, and then with a file.

Do not sharpen the blades directly on the mowing mechanism.
After sharpening, do not reinstall the blades yet, but check their balance. See the procedure below.

Before reinstalling the blades, check the shear pins that protect the mowing mechanism

from damage. If the shear pins are damaged, replace them immediately. Replacement pins
come with the machine.
After checking the balance and the shear pins, bolt the blades back on. When installing, make sure

the blades to not face upward inside the mowing mechanism cover. Do not switch the left one with the
right one. The right blade has leftward threads.
Carefully tighten the blades' mounting bolts using a torque wrench set to ±3 Nm. This torque is

reached at exactly the moment when the tangential spring under a blade's mounting bolt is completely
compressed. After that, do not tighten the screw further.
