sumption may increase somewhat if 10W-30 is
used. Therefore, check the oil level more regularly
if you use this type of oil).
Oil type, winter (< 4ºC): SAE 5W-30
(if this oil is not available, use SAE 10W-30).
Use oil without any additives.
Do not fill with too much oil. This can cause the
engine to overheat.
AIR FILTER - ENGINE
Clean the pre-filter once a year or after every 25
hours of operation, whichever comes first.
Clean the paper filter insert once a year or after
every 100 hours of operation, whichever comes
first.
Note! Both filters should be cleaned more often if
the machine operates on dusty ground.
1. Remove the protective cover of the air filter (fig.
10).
2. Dismantle the paper filter insert and the foam
pre-filter. Make sure that no dirt gets into the car-
burettor. Clean the air filter housing.
3. Change pre-filter once a year or every 25 hours
of operation.
4. Clean the paper filter insert as follows: Knock it
lightly against a flat surface. If the filter is very
dirty, change it.
5. Assemble in the reverse order.
Petroleum-based solvents such as kerosene may
not be used for cleaning the paper filter insert.
These solvents can destroy the filter.
Do not use compressed air for cleaning the paper
filter insert. The paper filter insert must not be
oiled.

ENGLISH
COOLING AIR INTAKE - ENGINE
The engine is air-cooled. A blocked cooling sys-
tem can damage the engine. The engine should be
cleaned at least once a year or every 100 hours of
operation.
Remove the fan casing. Clean the cooling fins on
the cylinder, the fan and the rotating protective
grille (fig. 12). Clean more frequently if mowing
dry grass.
BATTERY
The battery is a valve-regulated battery with 12 V
nominal voltage. The battery is completely main-
tenance free. You don't have to check or top up the
electrolyte level (fig. 13).
On delivery, the battery is in the accessories box.
The battery must be fully charged be-
fore being used for the first time. The
battery should always be stored fully
charged. If the battery is stored while
totally flat it could sustain permanent
damage.
If the machine is not going to be used for an ex-
tended period (more than 1 month), the battery
should be charged, disconnected and then stored in
a cool, safe place. Charge the battery completely
before reinstalling.
The battery can be charged in two ways:
1. You can allow the engine to charge the battery.
In this case it is very important, above all when
starting the machine for the first time and when
it has not been used for a long time, to allow the
engine to run continuously for at least 45 min-
utes.
2. Via a battery charger. This must be a charger
with constant voltage. The battery can be dam-
aged if a standard type battery charger (for acid
batteries) is used.
Do not short circuit the battery's termi-
nals. Sparks occur which can result in
fire. Do not wear metal jewellery which
can come into contact with the battery
terminals.
In the event of damage to the battery
casing, cover, terminals or interference
to the strip covering the valves, the bat-
tery should be replaced.
If the battery terminals are coated with oxide, they
