do not remove the spark plugs until the engine is totally
cold.
Clean the spark plugs and adjust the electrode gaps or replace them
after every 100 hours of operation.
• disconnect the spark plug caps and unscrew the spark plugs.
• Clean the electrodes [picture 17 item a ] with a wire brush to
remove any scale.
• Check the porcelain for cracks and make sure that the electrodes
are not excessively worn. If necessary, replace the spark plugs (P/n
18116).
Using a feeler gauge, check the electrode gaps [ b ] which should be
0.75 mm. If necessary, correct using the side of electrode only.
• Install the plugs and tighten them to 22 nm.
• Then connect the spark plug caps.
9•3•7 CooLING sysTeM
Before each use check that the air inlet grille at the back of the engine
hood is not blocked with grass or other debris and clean as necessary.
Once every year or every 100 hours of operation
• remove the air inlet conduit insert inside the engine hood and clean
the inside of the conduit (picture 18).
• remove the engine cooling volute and clean the cylinder cooling
fins and the inside of the cooling volute.
never turn the engine on before reinstalling all the
parts of the cooling system.

regularly clean the cooling fins of the hydrostatic axle and check that
the fan is also in serviceable condition.
have your eTesIA dealer change the oil and replace the oil
filter after 50 hours of operation, then every 250 hours.

The hydraulic fluid expansion cylinder is combined with the petrol
tank (picture 4).
Before unscrewing the hydraulic fluid cylinder cap, clean it carefully
and check that no impurities are able to enter into the cylinder.
Check the level of the hydraulic fluid before each use. do
not fill the expansion cylinder but make sure that the oil
level is always visible in it, (picture 4, item A), in particular
when the cold (normal level approximately 1 cm above the
bottom of the cylinder).We recommend a can of 10W40
grade oil P/n 38383 (2 liters).

9•5•1 MAINTeNANCe
Your mower has a lead storage battery in the engine compartment
requiring a minimum amount of servicing. Check the electrolyte level
every 50 hours. The level should be between the lower level (item [
MInI ]) and the higher level (item [ MAXI ]) in each of the cells.
If the electrolyte level of the battery (picture 27) when charged
is close to the [MInI] mark, add distilled water to bring it up to
[MAXI].

regularly check whether the battery terminals are oxidised. Where
applicable, clean and grease them.
If the battery has to be removed, always disconnect the negative
terminal first, followed by the positive terminal.

running.
Use a suitable 12V charger. The charge current must not
exceed 2A.
Connect to the charger to the right poles of the battery.
The charge time can be up to 12 hours depending on the initial charge
condition.
At the end of charging, check the level of the electrolyte. If
necessary, top up to the higher level using distilled water.
9•5•3 eLIMINATING youR BATTeRIes
Batteries contain dangerous material and should never be dumped
into the natural environment. They come under precise rules of
elimination (directive 2006/66/Ce). You can entrust your used
eTesIA batteries to your eTesIA dealer who will deal with their
elimination, or to selective refuse sorting facilities designed for the
purpose.
9•6 TyRe MAINTeNANCe
Always maintain the right tyre pressures:
- 1.2 kg/cm2 in the front wheels,
- 0.8 kg/cm2 in the rear wheels,
Other pressures than those recommended could have a negative effect
on turning or on the traction of the mower.
They could even cause loss of control of the mower .
The battery contains sulphuric acid which is particularly
dangerous and can cause serious burns in contact with
the skin or the eyes. Take great care when using it. Wear
protective clothing (gloves, goggles, etc) when topping
up the electrolyte level. In the event of contact with the
skin or the eyes, rinse in copious amounts of water. Where
applicable, contact a doctor immediately.
The battery and the acid must be kept out of reach
of children. never allow the battery to overflow. If it
overflows, rinse the party concerned immediately in copious
amounts of clear water to prevent their corrosion.
never disconnect the battery when the engine is
the battery gives off an explosive gas mixture during
charging. avoid any claims or sparks and do not smoke
nearby. do not carry out charging unless the room is
properly ventilated.
CAuTIoN!
A battery left in the discharge condition will
not recharge subsequently.
