Maintenance And Lubrication - Grillo MD22 N Manuel D'utilisation

By depressing the white button, you can choose the type of function to be displayed on the hour
meter.
4) To reset the hour meter 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.
TIPS 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 too
much.
4) Check the ground before mowing to make sure that there are no stones, sticks or foreign bodies.
5) Keep the engine at max.rpm during mowing, adjust the speed according to the height of the grass.
6) Keep the grids above the engine and the cooling fins of the hydraulic motor (fig. 4 – 6)
clean.
CUTTING POSITIONS
To choose the cutting height use the lever (fig. 2, no. 8). The deck can be set in 6 different cutting
positions from 25 to 105 mm. In case of uneven ground, humps or dips, put the mower deck in the
highest cutting position to avoid damage to the blades.
CUTTING ON SLOPES
Slopes must, wherever possible, be mown in the up/down direction, paying strict attention when
turning that the wheels uphill, 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 pay attention 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 may lose grip. Remember that if you engage the
differential lock and possibly the front emergency brake (fig. 1, n. 4) the machine is steadier.
INTERVENTION OF SAFETY DEVICES
The engine stops when:
– The operator gets up from the seat and the parking brake is not engaged.
The engine does not start if:
– The blade is engaged.
– Nobody is sitting in the driver's seat and the parking brake is not engaged.
– The forward lever is not in STOP position.
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.
ENGINE
For the lubrication intervals, follow the instructions provided in the engine manual. Engine oil must be
changed after the first 20 working hours, and then every 100 hours or every season, together
