Grillo MD16 Manuel D'utilisation page 11

– The lever (fig. 3, ref. 2) is also used to reverse. When it is moved back, the machine moves
backwards; always operate it gently.
PARKING BRAKE
To engage the parking brake lift up the loop (fig. 3, ref. 10) and hook the lever.
To adjust the parking brake use the register (fig. 5).
DIFFERENTIAL LOCK (ON MD16 ONLY)
The differential locking pedal is the one indicated in fig. 1 ref. 4.
Press the differential locking pedal in case of driving-wheels skidding. It is recommended to use the
differential lock on slopes and when driving downhill to keep the driving-wheels in adhesion.
Caution! Do not use the differential lock when bending.
In case of disengagement, keep lubricate with grease the coupling and the drive-chains.
ADJUSTMENT OF THE DIFFERENTIAL LOCK CHAINS (MD16)
If the chains of the chains of the diff lock system result to be loose, you have the possibility to tighten
them correctly by means of the adjustment bolts indicated in fig. 28. In order to tighten the chains in a
correct way you need to loosen the screws of the ball bearings (fig. 28, ref. A) on both parts and act then
on the bolts. (fig. 28, ref. B). Retighten the screws (fig. 28, ref. A).
CAUTION: do not tighten the chains too much; both branches shouldn't be too tighted.
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 engine (fig. 4 – 5) clean.
CUTTING POSITIONS
The cutting position is adjusted using the lever (fig. 2 ref. 8).
The deck can be set in 4 different cutting positions from 25 to 80 mm and one travel position in which the
blade disengages automatically.
In case of uneven ground, humps or dips, the deck should be kept in the highest cutting position to
prevent knocks by the blade.
SLOPING GROUND
If possible, steep slopes must be mown in the upwards/downwards direction, paying particular attention
when turning that the front wheels do not hit obstacles (stones, branches, roots, etc.) which might cause
the machine to overturn, or lead to loss of control.
Assess the conditions and pay particular attention if the ground and grass are damp since the machine
might slip. Use a low speed when driving downhill and do not pass over dry or cut grass since the
wheels lose grip; please remember that if you engage the differential lock (if you bought the MD16) your
machine will have higher adherence and stability.
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.
– The user is not sitting in the driver's seat.
– If the forward lever isn't at STOP setting.
