Maintenance And Lubrication - Grillo G84 Manuel D'emploi Et Entretien

– 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 gears do not engage:
– regulate the clutch by unscrewing the adjuster screw until the clutch release distance is
satisfactory. Remember that there must always be a little slack on the clutch cable.
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 carburettor.
– clean the engine and the machine thoroughly. Oil the handlebar support reversing mechanism.
CAUTION!
- 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.
ENGINE – Follow the instructions on lubrication intervals in the relative manual. In general users
are advised to check the oil level every 8 working hours and to change it every 100 hours. Always
use 10W30. Check the air filter every 8 working hours or more often in very dusty conditions. 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 (fig. 6) by removing the cap and checking
with the machine horizontal the oil reaches between the two notches. If necessary add MP 80
W/90 (API GL5 US-MIL-L-2105D) 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 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.
