Maintenance And Lubrication - Grillo GF3 Manual De Instrucciones

The following is a list of small problems which may occur during the use of the machine, which the
operator himself can remedy.
1) if the petrol engine does not start, check:
– 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 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, in the coil or in some other component. Contact your nearest
service centre or a specialist workshop.
2) if the Diesel engine does not start check:
– 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 free-play on the clutch cable (fig. 6)
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.
RUNNING-IN: change the engine oil after the first twenty working hours. Check that there are no
oil leakages or loose screws.
ENGINE – Follow the instructions on lubrication intervals in the engine manual. Users are
generally advised to check the oil level every 4 working hours and to change it every 100 hours.
Always use oil 15W40. Check the air filter element 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). For oil bath
filters use the engine oil to reach the appropriate oil level again. Check regularly that the fins of the
cylinder head and cylinder are not dirty by unscrewing the casings; follow the instructions in the
engine booklet.
