Routine Maintenance; Environmental Protection - GGP ITALY DML 504 AVS Gebrauchsanweisung

To prevent damage to the grass turf, use position «1» only on
perfectly flat, compact and level land.
• Only for models DML:
IMPORTANT NOTE - If discharge selection (
switched from position «B» (mulching) to another during work with
the lever in position «A» (rear discharge), turn off the machine and
remove grass on the sliding door (1); grass on the door may pre-
vent full discharge selection lever movement.
LAWN CARE RECOMENDATIONS
Each type of grass has different features and may thus require dif-
ferent ways to care for the lawn; always read the instructions on
seed boxes for mowing height for the growth conditions in the
work area.
Keep in mind that most grass is made up of a stem and one or
more leaves. If leaves are fully cut, the lawn is damaged and
growth is more difficult.
The following indications generally apply:
– too low a cut causes grass tears and uprooting, with a "spot-
ted" aspect;
– in the summer, cutting must be higher to avoid the ground from
drying;
– do not cut wet grass; this could reduce blade efficiency due to
sticky grass and tear the lawn;
– for particularly high grass, initially mow at maximum admitted
machine height followed by a second mow after two or three
days.
The appearance of the lawn will improve if you alternate the cut-
ting in both directions at the same height.

End of operations
When the work has been completed, release the brake lever (1)
and disconnect the spark plug cap (2). In models where applica-
ble, remove the starter key (3).
WAIT UNTIL THE BLADE STOPS before performing any work.

4. ROUTINE MAINTENANCE

IMPORTANT - Routine and accurate maintenance is essential
in maintaining original machine safety and performance lev-
els.
Store the lawnmower in a dry place.
1) Wear strong work gloves before cleaning, maintaining or
adjusting the machine.
2) Accurately wash the machine with water after cutting, remove
grass debris and mud accumulated in the chassis to prevent it
from drying and causing problems the next time the lawn-
mower is used.
3) In models with painted chassis, internal chassis part paint
may detach over time due to the abrasive action of cut grass;
in this case, promptly touch-up paint with rust-proof paint to
prevent rusting that could corrode the metal.
4) If accessing the lower part is necessary, only tilt the machine
on the side indicated in the engine manual, following the rele-
vant instructions. In models that include side discharge,
remove the discharge deflector (if installed-
5) Do not drip petrol onto the plastic parts of the engine or the
machine to prevent damaging them and remove all traces of
spilt petrol immediately. The warranty does not cover damage
to plastic parts caused by petrol.
6) In AVS models: in the event of abnormal handle vibrations,
check the vibration-proof sleeves and contact your Dealer to
replace them if damaged or worn.
4.1
Each intervention on the blade is best if conducted at a
specialised Centre that has the most appropriate tools.
Only blades with the following codes must be used on this
machine:
81004450/0 (for model 504)
81004453/0 (for model 554)
Blades must always be marked «GGP». Given the product evolu-
tion, the above mentioned blade may be replaced in time by oth-
ers, with similar interchangeable and operating safety character-
istics.
Reassemble the blade (2) with the code and markings facing the
ground, following the order indicated in the illustration.
Tighten the central screw (1) using a torque wrench set to 35-40
Nm.

2.5) needs to be
(1) following the instructions in the battery maintenance manual.
Do not connect the battery charger directly to the engine terminal.
It is not possible to start the engine using the battery charger as
a power source, as it may get damaged.
For prolonged lawnmower disuse, disconnect the battery from the
engine wiring, making sure the charge level is good.
The battery (2) can be accessed by removing the cover (3).

ing.
To clean the internal parts of the lawnmower:
– place the machine on firm ground;
– ower the cutting height as far as possible;
– connect a water hose to its pipe fitting (1);
– start the engine and initially clean in the same operating situa-
tion as before;
– stop the engine, move the discharge selection lever to the
opposite position, start the engine and clean again.

5. ENVIRONMENTAL PROTECTION

Environmental protection should be a priority of considerable
importance when using the machine, for the benefit of both social
coexistence and the environment in which we live.
– Try not to cause any disturbance to the surrounding area.
– Scrupulously comply with local regulations and provisions for
the disposal of waste materials after cutting.
– Scrupulously comply with local regulations and provisions for
the disposal of pakagings, oils, petrol, batteries, filters, dam-
aged parts or any elements which have a strong impact on the
environment; this waste must not be disposed of as normal
waste, it must be separated and taken to specified waste dis-
posal centres where the material will be recycled.
– At the time of decommissioning, do not pollute the environment
with the machine, hand it over to a disposal centre, in accor-
dance with the local laws in force.
