Maintenance And Lubrication - Grillo G55 Uso Y Mantenimiento

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 reaching the carburetor;
– that the vent hole on the fuel tank is not blocked;
– that the mesh filter at the carburetor intake is clean;
– that the carburetor jets are clean. Check by unscrewing them and if dirty, clean them with a jet of air;
– that the 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: points, capacitor, coil,
or in some other component. Contact your nearest service centre or a specialist workshop.
FOR LONG IDLE PERIODS
In case the machine is not to be used for a long period, the following precautions are recommended:
– empty the fuel tank and the carburetor;
– drain the oil from the engine;
– lubricate the cylinder by pouring in a spoonful of SAE 20 oil through the spark plug hole and then turning the
engine through a few revolutions by hand;
– clean the engine and the machine thoroughly. Oil the handlebar support reversing mechanism.
Proper maintenance and lubrication help to keep the machine constantly in perfect working order.
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 every 50 working hours by removing the cap and checking that with the machine
horizontal the oil reaches between the two notches. If necessary add MP 80 W/90 oil.
Change the oil once a year.
ROTARY TILLER - Check the oil level every 50 hours by removing the plug; the oil must almost fill the rotary tiller
box. If necessary add the same oil as for the gearbox.
HELPFUL HINTS FOR PROPER USE:
1) Important! Always use the clutch for forward and reverse travel.
2) Never leave the machine out in the rain.
3) Keep the reversing mechanism in the handlebar support clean and well oiled.
4) Never force the gearbox if the gear does not engage; give a succession of little touches on the clutch.
5) Never strain the engine: if smoke comes out of the exhaust, the engine is toiling and must be slowed down.
6) Even impossible ground can be tilled, but the machine must be well run-in first.
7) Never work at full throttle.
8) If the engine overheats on the first day, it must be stopped for a few minutes' rest.
9) Check the tyre pressure often (1.3 atm.).
10) When fitting the implements (e.g. rotary tiller) take care not to damage the centring device (see chapter on
«Implements»).
END OF SEASON MAINTENANCE
Clean the machine carefully; change the engine, gearbox and tiller gearbox oil. Clean the air filter.
Sharpen and grease the blades, replacing them if worn.
If parts have been broken and screws lost during the season, now is the time to restore everything to perfect working
order. Place two planks under the wheels.
Never keep the machine in animal sheds or near to chemical fertilizers, as this could cause certain parts to rust.
