Vibration while working
– Blades not balanced
– Balance blades or replace them if damaged
– Loose screws
– Check and tighten the screws that retain the blades,
the engine and the chassis
Oil light comes on
– Insufficient oil pressure
– Check oil level and top up if necessary
– Change oil filter
IMPACT WITH A STONE OR SOME OTHER FOREIGN OBJECT
- Stop the machine.
- Turn off the engine, lift up the cutting deck and check whether the blade fixing screws have been sheared, fit new
ones if necessary (110 cm deck), (B, fig. 21).
IMPORTANT
To move the machine with the engine off, lift and hook up the two levers located over the hydrostatic transmissions,
fig. 30; be careful because by doing this the self-braking device does not work any more.
MECHANICAL PARKING BRAKE
On machines fitted with this device the two cables (fig. 31) and the centre adjuster that compresses the spring must
be kept in check. The brake is applied by pulling the lever upwards, to release it press the button and lower the lever.
MACHINE WILL NOT KEEP A STRAIGHT LINE
Regulate the flow of oil in the two hydraulic motors by turning the nuts on the direction lever rods (fig. 32). Carry
out this operation with cold motors.
HOW TO INCREASE THE TRACTION POWER OF THE WHEELS
N.B.
With time, as more directional adjustments are made, by screwing in the 2 adjusting nuts (fig. 33) the power
at the wheels is reduced; to eliminate this problem proceed as follows:
Undo the two nuts completely (no. 1).
Set the advance lever to maximum speed (no. 2).
Put the two nuts in place “slightly tightened” (no. 1).
Put the centre screw in place to find the limit stop of the two levers (no. 3. it is important to limit how much the centre
limit stop screws in because this takes power away from the wheels).
At this point, in a yard, with the engine at low revs, adjust the direction by always screwing inwards one of the two
nuts (no. 1).
Adjust the neutral using the centre stud (no. 4). Start the engine with throttle at its minimum and the lever in neutral.
Loosen the lock nut and adjust by screwing in or out. Secure once more using the lock nut. An authorised service
centre should be contacted to perform this operation.
ELECTRICAL CIRCUIT
The electrical circuit is protected by fuses which, if blown, cause the whole electrical circuit to cut out. These are
located under the bodywork next to the engine and inside the instrument panel.
Once the fault has been located and repaired,
replace the blown fuse with one of the same rating.
Never replace a fuse with another of a different rating.
If the fault still persists even after having carried out the operation described above, contact the Authorised Service
Centre.
Never attempt to carry out complex repairs without having the necessary means and technical knowledge
available.
FINISHING WORK
Once mowing has been completed, disengage the blades, put the speed presetting lever in the STOP position (fig.
1 no. 1), set the throttle lever to idling speed, turn off the engine by turning the key (fig. 1 no. 8 and no. 8/A).
