FD450/ Translation of the original instructions
BLADE ENGAGEMENT
The engagement or disengagement of the blades is effected by operating the switch (fig. 2, no. 3).
When rotation is engaged the engine must be running at medium r.p.m and the machine must be
outside the area to be cut. Never start the blades with the engine running at maximum rpm. The
machine is fitted with an electromagnetic clutch which also stops the blades during
disengagement. The blades should stop within 5 seconds from disengagement. Should this not be
the case, adjust the three nuts of the electromagnetic clutch placing a 0.3 mm feeler gauge under
the brake plate. N.B. This operation must be carried out by an authorised service center only.
Do not use the machine if the blades do not stop within 5 seconds after disengagement with
the engine at max. rpm.
SLOPES
If possible always travel up and down rather than across slopes. When turning, take care that the
wheels on the uphill side do not meet any obstacles (stones, logs, roots, etc.) which might make
you lose control of the machine. If the drive wheels tend to slip, slightly raise the mower deck using
the hydraulic button or adjust the two floating springs (fig. 10, A) to put more weight on the forward
wheels to gain more traction. Always assess the working conditions and take care on damp ground
or wet grass since the machine might slip. When going downhill, start off slowly and try not to drive
over dry or cut grass because the wheels may lose grip. Never use this machine on slopes of more
than 12° (21%). If the wheels tend to slip, use the differential lock (fig.1 n.2).

HOURMETER

The machine is fitted with an hour meter with three different functions:
1) It always shows the no. of hours worked, even when the key is not inserted.
2) It displays the no. of hours to the next engine oil change (OIL CHANGE IN...HS). The first oil
change must be carried out after the first 20 working hours then every 100 working hours. The
indicator "OIL CHANGE" flashes automatically when it is necessary to change the oil.
3) It displays the no. of hours to the next lubrication (LUBE IN...HS). Lubrication must be carried
out every 40 working hours. The indicator "LUBE" flashes automatically when lubrication must be
carried out.
By pushing the white button, you can choose the function to be displayed on the hour meter.
4) To reset the hour meter after an engine oil change or after lubrication proceed as follows:
Push the button until the relative alarm flashes (OIL CHANGE IN...HS or LUBE IN...HS). Then
keep the button pushed for 6 seconds until the meter stops flashing.

SAFETY DEVICES

The engine should stop whenever:
- the operator leaves the seat while the parking brake is disengaged and the PTO is engaged.
- the operator presses the forward pedal when the parking brake is engaged.
The engine will not start if:
- the blades are engaged;
- the operator is not sitting in the driving seat and the parking brake is not engaged;
- the forward pedal is not in the stop position;
