IMPORTANT
In order not to compromise the
efficiency of the electromagnetic clutch:
– do not let the clutch come into contact with oil;
– do not spray pressurised water directly on the
clutch unit;
– do not clean the clutch with petrol.
Now remove the grass catcher, empty and rinse
it, then place it where it can dry quickly.
b) To clean the upper part
of the cutting-
means assembly:
– lower the cutting-means assembly completely
(position «1»);
– blow a jet of compressed air through the right
and left guard openings. Fig. 5.11)
5.4.11 Storage and inactivity
for long periods
If you intend not to use the machine for a long
period (more than 1 month), disconnect the
battery cables and follow the instructions in the
engine instruction manual.
Fig. 5.12) Empty the fuel tank by disconnecting
the tube (1) situated at the inlet of the fuel filter
(2), and collect the fuel in a suitable container.
Reconnect the tube (1) making sure you position
the clamp properly (3).
Put the machine away in a dry, sheltered place
and preferably covered with a cloth (see 8.5).
IMPORTANT
The battery must be kept in a
cool and dry place. Before a long storage period
(more than 1 month), always charge the bat-
tery, and then recharge before using again (see
6.2.3).
The next time the machine is used, check that
there are no fuel leaks from the tubes, fuel stop
-
cock or carburettor.
5.4.12 Circuit board protection device
The electronic circuit board has a self-resetting
protector which breaks the circuit if there is a
fault in the electrical system. This will stop the
engine and switch off the light.
The circuit automatically resets after a few sec
-
onds but the cause of the fault should be ascer-
tained and dealt with to avoid reactivating the
protection device.
IMPORTANT
To avoid activating the protec-
tion device:
– do not invert the leads on the battery terminals;
– do not use the machine without its battery or
damage may be caused to the charge regula-
tor;
– be careful not to cause short-circuits.
5.5 USING ON SLOPES (Fig. 5.13)
Observe the indicated limits (max 10° - 17).
WARNING!
Take care when beginning
forward movement on sloping ground to
prevent the risk of tipping up. Reduce the
forward speed before going on a slope, par-
ticularly downhill.
DANGER!
Never switch to reverse gear
to decrease speed when going downhill: this
could cause loss of control of the machine,
especially on slippery ground.
Mechanical transmission
DANGER!
Never ride the machine on
slopes in neutral or with the clutch out!
Always shift into a low gear before leav-
ing the machine at a standstill and unat-
tended.
Hydrostatic transmission
Drive down slopes with your foot off the drive
pedal (see 4.32) to use the braking effect of
the hydrostatic transmission when the trans
-
mission is not engaged.
5.6 SUGGESTIONS FOR MAINTAINING A
NICE LAWN
1. To keep a lawn green and soft with a good
appearance, it should be cut regularly with
-
out damaging the grass. A lawn can be com
-
posed of different types of grass. If the lawn
is cut frequently, grass and roots grow more
vigorously, forming a solid grassy bed. If the
lawn is cut is less frequently, higher grass
and weeds start growing (clover and daisies,
etc.).
2. It is always better to cut the grass when dry.
3. The cutting means must be in good condition
and well sharpened so that the grass is cut
straight without a ragged edge that leads to
yellowing at the ends.
4. The engine must run at full speed, both to
ensure a sharp cut of the grass and to get the
necessary thrust to push the cuttings through
the collector channel.
5. The frequency of mowing should be in rela
-
tion to the rate of growth of the grass, which
should not be left to grow too much between
one cut and the next.
