Maintenance And Lubrication - Grillo FD450 Bedienungsanleitung

BLADE ROTATION
The rotation of the blades is started and stopped using the switch (fig. 1, no. 1). When rotation is
engaged the engine must be running at medium rpm and the machine must not be in the area to
be cut. Never start the blades with the engine at maximum rpm. The machine is equipped with an
electromagnetic clutch which also brakes the blade during disengagement. Blades have to 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 authorized service center. Do not use the machine if the blades
do not stop within 5 seconds after disengagement with the engine at max. rpm.
SLOPING GROUND
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, adjust the cutting deck floating
springs to increase the load on the drive wheels and improve traction (fig. 10).
Always assess the working conditions and take care on damp grounds 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 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 equipped with the an hourmeter 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 than 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 hourmeter after the engine oil change or after lubrication proceed as follows:
Push the button until the relative alarm will flash (OIL CHANGE IN...HS or LUBE IN...HS). Then
keep the button pushed for 6 seconds until the alarm stops flashing.
SAFETY DEVICES
Remember that the engine stops whenever:
- the operator gets up from the seat, the parking brake is disengaged and the PTO is engaged.
In addition, 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 travel pedal is not in the stop position;
If you start off the machine with the parking brake engaged, the engine stops.
CAUTION!
- Disconnect the plug before performing any cleaning, maintenance or repair operation.
Always wear suitable clothing and working gloves.
- When the machine or part of it is lifted to carry out maintenance operations, always
remember to use suitable fixing tools such as holders and safety locks.
- When carrying out maintenance operations and/or when the machine is tilted without
safety locks or supports, never leave it unguarded in places where inexperienced people
and children could have easy access to it.
- Protect the environment: carefully dispose of used oils, petrol and any other pollutant
product!
- Effective maintenance and correct lubrication help to keep the machine fully efficient.
