Routine Maintenance - GGP SBC 425 H Operator's Manual

Keep the machine slightly tilted so that the low-
er part of the cutting line head does not touch
the ground and the cutting line is at the required
point, always keeping the cutting device at a dis-
tance from the operator.
c) Cutting near fences/foundations
(Fig. 13)
Slowly move the cutting line head near fenc-
es, posts, rocks, walls, etc. without hitting them
hard.
If the line strikes a solid object it could break or
become worn; if it gets tangled in a fence it could
break abruptly.
In any case, cutting around pavements, founda-
tions, walls, etc. can cause greater wear than
normal to the line.
d) Cutting round trees (Fig. 14)
Walk round the tree from left to right, approach-
ing the trunks slowly so as not to strike the tree
with the line and keeping the cutting line head
tilted forward slightly.
Remember that the nylon line could lop off or
damage small shrubs and that the impact of the
nylon line against the trunk of bushes or trees
with soft bark could seriously damage the plant.
e) Adjusting line length when working
(Fig. 15)
This machine is fitted with a "Tap & Go" head.
To release more line, tap the cutting line head
against the ground with the engine at top speed:
the line will be released automatically and the
knife will cut off the excess length.
4.4 WHEN WORK IS FINISHED
When you have finished your work:
– S top the machine as indicated previously (see
3.3).
– Wait for the cutting device to stop and then
mount the blade guard.

5. ROUTINE MAINTENANCE

Correct maintenance is essential to maintain
the original efficiency and safety of the machine
over time.
WARNING!
tions:
– Remove the spark plug cap.
– Wait until the engine is sufficiently cold.
– Use protective gloves when handling the
blades.
– Keep the blade protection device on, ex-
cept when intervening directly on the blade.
– Never dispose of oils, fuel or other pollut-
ing materials in unauthorised places.
5.1 STORAGE
At the end of each working session, carefully
clean the machine of dust and debris, and make
sure that there are no damaged parts, replacing
any faulty parts. The machine must be stored in
a dry place away from the elements and with the
cover correctly fitted.
5.2 CLEANING THE ENGINE
AND THE SILENCER
To reduce fire risks, periodically clean the cylin-
der fins with compressed air and clear the silenc-
er area to get rid of sawdust, branches, leaves or
other debris.
5.3 STARTING UNIT
To avoid overheating and damage to the engine,
always keep the cooling air vents clean and free
of sawdust and debris.
If you notice signs of wear on the starter cable,
contact your Dealer for a replacement.
5.4 NUTS AND SCREWS
Periodically check that all the nuts and screws
are securely tightened and the handgrips are
tightly fastened.
5.5 CLEANING THE AIR FILTER (Fig. 16)
IMPORTANT Cleaning the air filter is essential 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 damage the
engine.
It must be cleaned after every 8-10 working
hours.
