Routine Maintenance - GGP ITALY BL 260 H Manual De Instrucciones

IMPORTANT When used as a vacuum collector
not collect damp grass or leaves to avoid clog ging
the rotor and coil.
IMPORTANT When using the machine as a vac-
uum collector, there is a risk of inadvertently suc-
tioning objects which can obstruct the machine
and block the rotor. In this case:
– switch the motor off immediately;
– disassemble the vacuum tube;
– remove the foreign body from inside the vacu-
um inlet.
Check that nothing is blocking the rotor or volute
before using the machine again.
IMPORTANT A too full bag reduces ma chi ne ef-
ficiency and could cause the engine to o ver heat.
4.3 END OF OPERATIONS
When you have finished your work:
– Switch off the engine as indicated above
(Chap. 6).
– Disconnect the spark plug cap.
– Empty the bag if used as a vacuum collector.
– If the blower tubes are removed, replace the
fa s tening screw (1) and relevant washers
(2) (Fig. 1 and 2).
– If the vacuum tubes are removed, close the
gril l e (6) and tighten the knob (5) (Fig. 2).

5. ROUTINE MAINTENANCE

Correct maintenance is essential to maintain
the original efficiency and safety of the machine
over time.
WARNING! During maintenance opera­
tions:
– R emove the spark plug cap.
– W ait until the engine is sufficiently cold.
– Wear protective gloves.
– D o not work on the machine if not in pos­
session of the necessary skills and tools.
5.1 STORAGE
After every working session, clean the machine
tho r oughly to remove all dust and debris, and re-
pair or replace any faulty parts.
The machine must be stored in a dry place away
from the elements.
5.2 CYLINDER AND SILENCER
To reduce fire risks, periodically clean the cylin-
der fins with compressed air and clear the si l e n -
cer area from dust, leaves or other debris.
5.3 STARTING SYSTEM
To avoid overheating and damage to the engine,
always keep the cooling air vents clean and free
of sawdust and debris.
The starter rope must be replaced as soon as it
shows signs of wear.
5.4 NUTS AND SCREWS
Periodically check that all the nuts and screws
are securely tightened and the handgrips are
tightly fastened.
IMPORTANT Cleaning the air filter is es sential to
guarantee the efficiency and duration of the ma-
chine. Do not work with a damaged filter or with-
out a filter, as this could permanently da mage the
engine.
It must be cleaned after every 8-10 working
hours.
Clean the filter as follows:
– L oosen the knob (1), remove the cover (2) and
the filter element (3).
– W ash the filter element (3) with soap and wa-
ter. Do not use petrol or other solvents.
– L eave the filter to dry in the open air.
– R eplace the filter element (3) and the cover
(2) and tighten the knob (1).
5.6 CHECKING THE SPARK PLUG (Fig. 8)
Periodically remove and clean the spark plug
u s ing a metal brush to get rid of any deposits.
Check and reset the correct distance between
the electrodes.
Replace the spark plug and fasten it firmly using
the supplied wrench.
The spark plug must be replaced with one with
the same characteristics whenever the electro-
des have burnt or the insulation has worn, and in
any case every 50 working hours.
5.7 TUNING IDLE SPEED (Fig. 9)
IMPORTANT Idling must be adjusted when the
engine tends to turn off or no significant speed dif-
ferences are noted when using the throttle.
Adjustment is performed after starting the en-
gi n e and letting it run idle for several minutes,
u s ing the screw (1):
– t urn clockwise to increase engine rpm;
