Maintenance - Etesia Pro 53 LKX User Manual

Disconnect the spark plug cap before any maintenance and
shut the petrol cock.
The best maintenance is above all the regular cleaning of your
mower after each use (frame, wheels, transmission system...).
CLeaning
• Never use a hot water washer.
• After stopping the engine and allowing it to cool, unhook the grass
bag and lay the mower on the right hand side so that the carburettor is
uppermost.
• Clean the lawnmower particularly the inside of the cutting deck.
Remove all debris of cut grass, preferably using a scraper and a
brush.
• Never use a high pressure washer on the transmission parts or
engine.
• If you are using a water jet, and particularly when using a high
pressure washer, take care not to splash water on engine and
transmission elements such as the carburettor, air filter, ignition,
exhaust.
• After cleaning, it is recommended that the engine be started and
transmission used to disperse any excess water.
• Put the blade on several times to dry the braking parts.
engine MainTenanCe
Before any maintenance operation and in order to avoid any
risk in case of accidental start of the mower, take out the
plug top and empty the engine outside.
engine eMPTying
• The first emptying has to be done after the 5 first working hours.
These hours have to be considered like a burn in period during the
one you have to run the engine carefully.
• Next emptying has to be done every 50 hours or once a year. If the
mower is used in hard conditions (high temperatures and loads),
change the oil more often.
Be careful with used hot oil.
eMPTying MeTHod
• Cut off the fuel tap and start the engine until the carburettor tank
becomes empty.
• As long as engine is hot, do the emptying through the filling hole.
The flowing out will be easier if this operation is done after cooling.
• Remove the oil cap and lay the mower on the side
page 9).
• Take the used oil back in a receptacle at the filling tube exit.
remove the used oil in an approved recuperation station.
• Put the mower back on its wheels, clean carefully the oil gauge
and the tube contour and complete with oil (cf chapter 'engine
preparation' page 11).
sParK
• Clean periodically the electrode and check their spacing with a (0.7
to 0.8 mm) block. Do not hesitate to replace used spark. Replace
the spark every 100 hours. Use only ETESIA original spark plugs
designed for these engines (part number 3861).

engine filter regularly: every 25 working hours. In case of use in dust
atmosphere, the number of cleaning has to be increased.
• Unscrew the screws [a] and take out the top [b].
• Clean carefully the top. Take out, carefully, the paper cartridge
[c] and pre filter elements [d]. Replace them as soon as they are
damaged.
• Clean the pre filter elements with liquid detergent and clear water
and dry them completely.
• Oil the pre filter elements and press them in your hand to eliminate
all the surplus.
• Clean the paper cartridge by taping it gently on a flap surface or
replace it in case of necessity.
• Reassemble the filter components [d] and [c], reinstall the cover [b]
and screw down the screws or nuts [a].
