Maintenance And Lubrication - Grillo G55 Manual De Uso

Translation of the Original Instructions
NOTE: to avoid problems to the clutch during the functioning of the machine, please keep the red
lever firmly depressed. Attention! Do not use the machine whilst only partially depressing the red
lever or damage to the clutch may result.
END OF WORK
When work is ended, to turn the engine off, turn the switch positioned on the handle 14 (Fig. 1A),
position OFF for petrol engines. For Diesel engines, turn the handle 15 (Fig. 1B). Set the gear and
P.T.O. in neutral position.
TROUBLESHOOTING
The following is a list of small problems which may occur during the use of the rotovator, which the
operator himself can remedy.
1) if the petrol engine does not start, check as follows:
– that the fuel tank is at least half full;
– that the petrol cock is turned on;
– that the choke is engaged (when the engine is cold);
– that fuel is normally going to the carburettor;
– that the vent hole on the fuel tank is not blocked;
– that the mesh filter at the carburettor intake is clean;
– that the carburettor jets are clean. Check by unscrewing them and if dirty, clean them with a jet of
air;
– that spark plug is generating a spark. To check this, remove the spark plug, re-connect it to the
electricity supply wire, rest the metal side on an electrical earth and turn the engine-pulley as if to
start it. If no spark is seen between the electrodes, check the connection of the spark plug cable; if
there is still no current replace the spark plug with a new one. If a spark is still not obtained, the
problem is in the electric system: capacitor, coil, or in some other component. Contact your nearest
service centre or a specialist workshop.
2) if the Diesel engine does not start check as follows:
– that the fuel tank vent hole is not blocked;
– that the fuel tank is at least half full.
3) If the gears do not engage:
– regulate the clutch using the adjuster screw until the clutch release distance is satisfactory.
Remember that there must always be a little slack on the clutch cable.

MAINTENANCE AND LUBRICATION

Proper maintenance and lubrication help to keep the machine constantly in perfect working order.
RUNNING-IN: change the engine oil after the first twenty working hours.
ENGINE
- Follow the instructions on lubrication intervals in the relative manual. In general users
are advised to check the oil level every 4 working hours and to change it every 50 hours. Always
use 15W40. Check the air filter oil level every 8 working hours or more often in very dusty
conditions. Top up with the same oil as for the engine (see engine handbook). On versions with dry
filter, replace the cartridge if clogged (do not clean with compressed air jets).
GEARBOX - Check the oil level (Fig. 6) every 50 working hours by removing the cap and checking
with the machine horizontal the oil reaches between the two notches. If necessary add MP 80
W/90 (US MIL-L-2105D) oil.
Change the oil once a year.
