Tire Pressure - Grillo G131 Manual De Uso Y Mantenimiento

MAINTENANCE
The motor mower 131 does not require special maintenance. However, to keep it at its best performance it is advisable
to effect the following operations:
– Check that all screws and nuts are tightened;
particularly the nuts fixing the cutter bar to the machine.
– Sharpen the blade frequently; to do this it is necessary to slip off the blade from the bar, removing first the blade
coupling no. 3 (fig. 20) which is fixed by two screws. Sharpen the blade with the special grindstone, then fix it on
again making sure to tighten the two fixing screws of the blade coupling.
– Check the ledger plates frequently (fig. 21). They must be neither too tight to block the blade, nor too loose to allow
too much clearance.
Warning: when the rotary tiller is put back in place do not forget to re-activate the safety device no. 17 (fig. 3).
SNOW THROWER
This implement has been especially designed for the 131 and it is very useful for clearing snow from squares, access
roads and garage entries.
It consists of a turbine rotary unit enclosed in a special case open on the front, which turning at high rotation speed,
collects snow and then throws it through a pipe whose inclination can be adjusted as desired.
Snow can thus be thrown 10-12 mts away (33'-40') in any desired direction. The snow thrower is attachable to the
flange for implements with the handles turned by 180° and with the same levers as for the motor mower plus another
lever to adjust the orientation of the pipe (fig. 23).
Warning: if the rotary tiller is put back into place, remember to return the safety device (no. 17 fig. 3) to its original
operating condition.
The snow thrower is 70 cms (27.5") wide and can clear off snow up to 40 cms (16") high. Wheel-weights should be
used for a better grip on the ground.
If the snow is very wet, keep the discharge pipe pointing straight forward to avoid obstructions at the outlet.
Maintenance: when work is over, any snow deposited inside the snow-thrower should always be removed, in order
to prevent from blocking the turning turbine by freezing. Check the oil level inside the central box carrying the bevel
gear pair frequently. If necessary add lubricant for gearboxes MP 80W/90.
