8• REGULAR MAINTENANCE
Adjustment of the clutch cable tension :
This value can be adjusted without any tools by loosening the
thumbwheel provided on the device. Tighten the thumbwheel again
after making the adjustment.
8•4 CHECKING THE SAFETY DEVICES
• Ensure that the safety control is working properly : holding bar of
the safety device released = the cutting blade stops in less than 3
seconds.
• Regularly check that the safety flap is in place and in good
condition. Have it replaced if it shows any signs of wear or
damage.
If you notice any irregularity in operation, have the safety system
checked by your ETESIA dealer.
8•5 REGULAR MAINTENANCE OF THE
ENGINE
8•5•1 LUBRICATION - OIL CHANGE
Regularly check the engine's oil level : every 5 hours or before
each use.
• Place the mulching mower on an unencumbered horizontal
surface.
• Clean carefully around the edge of the filler neck and cap.
• Unscrew the filler neck cap and take out the dipstick.
• Wipe the dipstick with a clean cloth, put it back in the filler neck
and screw the cap back on.
• Unscrew the cap again and take out the dipstick to check
the oil level. The oil must reach the "F" mark. Top up if
necessary. Do not fill the oil sump beyond the "F" mark on
the dipstick.
• Screw the filler neck cap down firmly before starting the
engine.
Replace the engine oil after the 5 first hours of operation, then
every 50 hours or every year. Change the oil every 25 hours if the
machine is used at high ambient temperatures or loads.
When the engine is still hot, change the oil using the oil filler
neck.The oil will run out more easily than it would if it were
cold.
• Before tipping the mulching mower up to empty the oil out,
close the fuel cock and turn the engine over until the carburettor
chamber is empty.
• Whilst the engine is still hot, unscrew the filler neck cap and take
out the dipstick, then tip the mulching mower onto its left side
over a container in which you can collect the used oil as it comes
out of the filler neck (picture 17).
BE CAREFUL WITH THE HOT OIL.
• Place the mulching mower back on its wheels.
• Carefully clean around the filler neck and the dipstick.
• Through the filler neck, slowly pour in the new oil.
• Check the oil level. Top up if necessary.
Take the used oil to an approved recovery center.
8•5•2 AIR FILTER (PICTURE 8)
Maintain the engine's air filter regularly : every 50 hours or once
a year. Clean it more often if the mulching mower is used in very
dusty conditions.
• Unscrew the button (a) and remove the air filter cover (b).
• Remove the paper element (d) from the bottom and the pre-filter
(c) from the cover.
• Wash or replace the pre-filter unit every year or after every 25
hours of use, and more frequently in extremely dusty or dirty
conditions.
• Insert the new filter element with the folded side facing outwards
and place the rubber seal around the edge of the base.
• Replace the pre-filter and air filter cover and fasten with the
button.
8•5•3 SPARK PLUG
Always use a spark plug with the right thermal value.
To ensure the engine functions properly, the spark plug must not
show any fouling and its spark gap must be correct.
• Remove the spark plug cap and take out the spark plug with a
plug spanner.
If the engine has just been running, be careful not to burn
yourself.
• Inspect the spark plug visually and throw it away if the
electrodes are worn or if the insulation is cracked or
chipping. If you are going to reuse the spark plug, clean it
using a wire brush.
• Measure the gap (a) between the electrodes (picture 19) using
a spark plug gauge. Correct it if necessary by moving electrode
(b). The gap must be 0.75 mm.
• Replace the spark plug every 100 hours of operation or once a
year. Do not hesitate to change a worn spark plug.
• Check that the spark plug washer is in good condition and screw
the plug back in by hand to avoid damaging the thread.
• After putting the spark plug in place, tighten it using a spark plug
spanner to compress the washer.
• When installing a new spark plug, tighten it half a turn after
it is in its seat to compress the washer. When installing a used
spark plug, tighten it 1/8-1/4 of a turn after it is in its seat to
compress the washer.
The spark plug must be tightened correctly. If the spark plug
is not tight, it risks o verheating considerably and damaging the
engine.
8•5•4 COOLING SYSTEM -
CARBURETTOR
• Regularly remove the grass from around the starter. Remove
from the ventilation grille and around the engine the grass that
builds up there. In this way you will be sure of the constant
and efficient cooling of your engine.
The carburettor control linkage must be kept perfectly clean.
