Front Brake; Parking Brake - Grillo MD22 Manual De Instrucciones

MD22/ Translation of the original instructions

FRONT BRAKE

The front brake (fig. 22, no. 1) must be used only as emergency brake, sloping down to avoid the
machine sliding. If used with the differential lock, it makes the machine steadier on slopes. The forward
travel lever is normally used to decelerate and to brake.

PARKING BRAKE

To engage the parking brake, please press the lever upwards and lock it to the proper seal retainer (fig.
23, no. 2); in this position, if the forward travel lever is engaged, an acoustic signal warns that the
parking brake is engaged. To adjust the parking brake, use the castellated nut (fig. 21).
HOUR METER
The machine is equipped with the an hourmeter (fig. 1, no. 2) 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 50 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.
CUTTING POSITIONS
The cutting position is adjusted using the lever (fig. 34). The deck can be set in 4 different cutting
positions from 30 to 90 mm and one travel position in which the blade disengages automatically (fig. 1D).
In case of uneven ground, humps or dips, the deck should be kept in the highest cutting position to
prevent knocks by the blade.
SLOPES
If possible, steep slopes must be mown in the up/down direction, taking great care when turning that the
wheels upstream do not strike obstacles (stones, branches, roots, etc.) which might cause the machine
to overturn, or lead to loss of control. Assess the conditions and take care if the ground and grass
are damp since the machine might slip. Downhill, set off at low speed and do not pass over dry or cut
grass since the wheels lose grip;
INTERVENTION OF SAFETY DEVICES
Remember that the engine will stop whenever:
– The operator gets up from the seat.
The engine will not start up if:
– The blade is engaged.
– Nobody is sitting in the driver's seat.
– If the cutting deck isn't at the highest setting.
USEFUL RULES FOR EFFICIENT USE
1) Never strain the engine: when fumes are emitted from the exhaust it means that it is being strained.
Slow down.
2) Do not leave the machine out in the rain.
3) Frequently sharpen the mower blades: the cut will be better and the engine will not be strained as
much.
4) Check the land before mowing to make sure that there are no stones, sticks or foreign bodies.
5) Keep the engine at peak r.p.m. during mowing, adjust the speed according to the height of the grass.
6) Keep the grilles above the engine and the cooling fins of the hydraulic motor (fig. 5 – 7) clean.
