8• MAINTENANCE
WARNING !
Lift this machine by using a lift table able
to support the weight of it (see technical specifi cation).
8•1 ENGINE MAINTENANCE
Before carrying out any maintenance, stop the engine, and
remove the ignition key.
Never touch the exhaust pipe, the cooling cylinder or fi ns,
to avoid the risk of burns.
8•1•1 CHECKING THE OIL LEVEL
• Check oil level before using the mower.
• Put the ride-on brush cutter on a fl at surface.
• Clean the area around the fi lter neck to prevent dirt from entering
the sump.
• Remove the dipstick (see a picture 3 page 10).
• Wipe the gauge with a clean cloth and place it back in the fi ller
tube.
• Put back the cap so that it bears on the tube but do not screw it
down.
• Pull out the dipstick to check the level: the level of the oil on the
dipstick should be between the [ADD] and [FULL].
• Screw the dipstick back in securely.
8•1•2 DRAINING THE ENGINE OIL
• After the initial servicing at 15 hours, to be performed by your
ETESIA dealer, the engine oil must be changed at the fi rst of the
following occasions: every 50 hours or once each year.
• Change the oil when the engine is still hot to obtain better outfl ow
of oil than when cold.
• Position the machine on a fl at surface.
• Stop the engine, and remove the ignition key.
• Place a suitable recipient at the oil drain outlet.
• Unscrew the drain plug (see b picture 3 page 10) and drain the used
oil into a container.
WARNING ! Special care should be taken when draining
hot oil. Wear gloves.
• Close again the drain plug.
• Clean the perimeter of the fi ller hole to prevent impurities from
getting into the housing.
• Remove the oil gauge and slowly pour in 10W40 multigrade oil,
specifi cation API-SL or ACEA-A3 P/N ETESIA 38383 (2 liters) or
an SAE30 monograde oil through the fi ller pipe.
• Wipe the gauge with a clean cloth and place it back in the fi ller
tube.
• Rest the plug on the tube without screwing it down.
• Check the oil level using the dipstick. The level should reach but
not exceed the [FULL] marker.
• Screw the plug down.
• Dispose of used oil at an approved collection point.
8•1•3 CHANGING THE OIL FILTER
• Change the oil fi lter after 100 hours of operation or once per season.
• Oil the gasket with clean oil before installing a new fi lter.
• Hand tighten the fi lter until the joint gives impermeability. Then
turn another 1/2 to 3/4 turn.
• Start the engine and let it run.
• Check the permeability. Switch the engine off, check the oil level
and if necessary top up.
8•1•4 AIR FILTER (PICTURE 4 PAGE 10)
• Clean the air fi lter every 50 hours, and more frequently under very
dusty conditions of use.
• Take off cover.
• Remove the butterfl y nuts (1) and remove the complete air fi lter.
• The foam element (3) (prefi lter) : wash with detergent and water
and dry well. Add a little oil and squeeze to eliminate excess oil.
• Paper fi lter (2) : gently tap to knock dust off. Replace with a new
element every 100 hours, or at least once every year.
WARNING !
Do not wash the paper element with solvent
or petrol. Do not add oil to it or dry it with compressed air,
because this would cause damage.
WARNING !
Reduce cleaning and replacement intervals
in a dusty atmosphere.
8•1•5 SPARK PLUG (PICTURE 5 PAGE 10)
WARNING !
Do not attempt to change the spark plug
until the engine is completely cold.
• Clean or replace the spark plug after every 100 hours of service.
- Disconnect the spark plug lead and remove the spark plug.
- Clean the electrodes (a) using a metal brush to remove carbon
deposits.
- Check that the porcelain is not cracked and that the electrode is
not excessively worn. Replace the spark plug if necessary.
- Check the spark gap (b) using a feeler gauge. The gap should
measure between 0.7 and 0.8 mm. Adjust the gap if necessary
using only the outer tab.
- Refi t the spark plug and tighten with a torque of 20 Nm.
- Reconnect the spark plug lead.
8•1•6 PETROL FILTER (PICTURE 6 PAGE 10)
• If your engine lacks power or misfi res this may be due to dust in the
petrol fi lter, in which case the fi lter must be changed.
• However, we recommend the fi lter to be changed every 300 hours
or at least once a year, even if it looks to be in good working order.
8•1•7 COOLING SYSTEM
• Before using the mower and during the use of it, always check that
the rotating engine grid is not blocked by grass or other debris.
Clean, if necessary.
• Once a year or after 100 hours of service, as appropriate, remove
the fan cover and clean the areas indicated in order to prevent the
engine from overheating, racing or being otherwise damaged (see
picture 7 page 10). Clean more frequently, if necessary.
WARNING !
Clean the area around the silencer regularly
to remove grass, dust and fl ammable debris.
Do not attempt to carry out major repairs unless you are equipped
with the appropriate tools and are suitably skilled to repair internal
combustion engines.
8•2 MAINTENANCE OF THE
TRANSMISSION AV95 AND AV98
• When carrying out work on the transmission system, always switch
off the engine and remove the ignition key.
• Regularly clean the grid of the ventilator of the transmission system.
