DRIVING TIPS
Make sure that there is the correct quantity of oil in
the engine when driving on slopes (oil level on
"FULL/UPPER").
Be careful when driving on slopes. No
sudden starting or stopping when mov-
ing up or down a slope. Never drive
across a slope. Move from the top down,
and from the bottom to the top.
When driving down slopes the rear
wheels can lift off the ground. However,
the cutting deck prevents the machine
from tipping over forwards.
The machine, equipped with original
accessories, may not be driven on slopes
greater than 10º in any direction.
Reduce the speed on slopes and when
making sharp turns to prevent the ma-
chine from tipping over or you losing
control of the machine.
Do not turn the steering wheel to full
lock when driving in top gear and at full
throttle. The machine can easily topple
over.
Keep hands and fingers well away from
the seat bracket. Risk of crushing inju-
ries. Never operate the machine without
the engine casing.
Never drive with the cutting deck in the
raised position. This damages the deck
drive belt.

SERVICE AND MAINTENANCE

SERVICE PROGRAM
We recommend that an authorised workshop car-
ries out every service. This guarantees that the
work is performed by trained personnel and with
genuine spare parts.
PREPARATIONS
Unless otherwise stated, all service and mainte-
nance must be carried out on a stationary machine
when the engine is not running.
Prevent the machine from rolling by al-
ways applying the parking brake.
ENGLISH
Prevent unintentional starting of the
engine by always stopping the engine,
disconnecting the spark plug cable
from the spark plug and earthing it.
Disconnect the negative cable from the
battery.
CLEANING
To reduce the risk of fire, keep the en-
gine, silencer/catalytic converter, bat-
tery and fuel tank free from grass,
leaves and oil.
To reduce the risk of fire, regularly
check the machine for oil and/or fuel
leakage.
When washing the machine with water under high
pressure, do not point the jet directly at the trans-
mission.
Do not point jets of water directly at the engine.
Use a brush or compressed air in order to clean it.
ENGINE OIL
Change engine oil the first time after 5 hours of op-
eration, and subsequently after every 50 hours of
operation or once a season.
Change the oil more often (after 25 hours of oper-
ation or at least once a season) if the engine has to
operate under demanding conditions or if the am-
bient temperature is high.
Change oil when the engine is warm. Always use
a good grade of oil (service grade SF, SG or SH).
The engine oil may be very hot if it is
drained off directly after the engine is
shut off. So allow the engine to cool a
few minutes before draining the oil.
Unscrew the oil drain plug (fig. 8). It is situated on
the left of the engine (machine viewed from the
rear).
Collect the oil in a collection vessel. Then take
the oil to a recycling station. Do not allow oil to
get on the V-belts.
Screw in the oil drain plug.
Remove the dipstick and fill up with new oil to the
"FULL" mark.
