Routine Maintenance; Cutting Means Maintenance - GGP ITALY MCS 504 Serie Manuel D'utilisation

4. ROUTINE MAINTENANCE

Store the lawnmower in a dry place.
IMPORTANT Routine and accurate maintenance is es-
sential in maintaining original machine safety and perform-
ance levels.
Adjustments or maintenance operations must only be per-
formed with the engine switched off and the spark plug ca-
ble disconnected.
1) W ear strong protective gloves before cleaning, main-
taining or adjusting the machine.
2) A ccurately wash the machine with water after cutting;
remove grass debris and mud accumulated in the chas-
sis to prevent it from drying and causing problems the
next time the lawnmower is used.
3) On models with painted chassis: paint on internal
chassis parts may start to flake over time due to the
abrasive action of cut grass; if this happens, promptly
touch-up with rust-proof paint to prevent rusting that
could corrode the metal.
4) I f accessing the lower part is necessary, only tilt the ma-
chine on the side indicated in the engine manual, follow-
ing the relevant instructions.
5) Do not drip petrol onto the plastic parts of the engine or
the machine to prevent damaging them and remove all
traces of spilled petrol immediately. The warranty does
not cover damage to plastic parts caused by petrol.
6) O n models with AVS: If the handle vibrates unusual-
ly, check the anti-vibration sleeves and contact your
Dealer.
7) T o ensure that the machine will function properly over
time, it is highly recommended to change the engine oil
regularly, following the timing indicated in the engine's
Instruction Manual.
The oil can be discharged at a specialised servic-
ing centre, or by using a syringe to suction the oil out
through the filler spout, bearing in mind you may need
to repeat the operation several times in order to com-
pletely empty the tank.
Remember to top-up with oil before using the ma-
chine again.

4.1 Cutting means maintenance

It is best if all interventions on the cutting means are done
at a specialised Centre that has the most appropriate tools
and equipment.
Only cutting means bearing the code indicated in the table
on page ii must be used on this machine.
Given product evolution, the above mentioned cutting
means may be replaced in time with others having similar
interchangeable and operating safety features.
Reassemble the cutting means (2) with the code facing
the ground, following the steps indicated in the illustration.
Tighten the central screws (1) using a torque wrench set to
the values specified for each type of cutting means.
4.2 Drive adjustment
On power-driven models, remove the guard (1) once or
twice a year by unscrewing the screws (2) and releas-
ing the fittings (3). Then clean carefully using a brush or
compressed air, removing the grass and dirt from the area
around the transmission and belt. Always reassemble the
guard (1).
