Cleaning The Air Filter; Spark Plug; Angle Transmission; Nuts And Bolts - GGP ITALY B 26 J Manual De Instrucciones

• To avoid overheating and damage to the
engine, always keep the cooling air vents
clean and free of sawdust and debris.

7.5 CLEANING THE AIR FILTER

IMPORTANT Cleaning the air filter is
essential to guarantee the efficiency and
durability of the machine. Do not work with
a damaged filter or without a filter, as this
could permanently damage the engine.
It must be cleaned after every 15 working hours.
Clean the filter as follows:
• Loosen the knob (fig. 21.B), remove the cover
(fig. 21.A) and the filter element (fig. 21.C).
• Wash the filter element (fig. 21.C) with soap
and water. Do not use petrol or other solvents.
• Leave the filter to dry in the open air.
• Fit the filter element (fig. 21.C) and the
cover (fig. 21.A), back on, tightening
the knob (fig. 21.B) again.
7.6

SPARK PLUG

Periodically remove and clean the
spark plug using a metal brush (fig.
22) to get rid of any deposits.
Check and reset the correct distance
between the electrodes (fig. 22).
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
electrodes have burnt or the insulation has worn,
and in any case every 100 working hours.
7.7

ANGLE TRANSMISSION

Lubricate with lithium-based grease.
Remove the screw (fig. 23.A) and put in the
grease, turning the shaft manually until grease
emerges, then replace the screw (fig. 23.A).

7.8 NUTS AND BOLTS

• Keep all nuts, bolts and screws tight to be sure
the machine is in a safe working condition.
• Check regularly that the
handles are fixed firmly.

8. EXTRAORDINARY MAINTENANCE

8.1 CUTTING MEANS MAINTENANCE

When servicing the cutting means, bear in
mind that, even though the spark plug cable is
disconnected, the cutting means can still move.
8.1.1 Sharpening 3-point blade,
saw blade (if permitted)
IMPORTANT For safety reasons, sharpening
and balancing should be done by a Specialised
Centre with suitable skills and equipment
for the job to avoid damage to the blade
that would make it unsafe when used.
3-point blades can be used on both sides.
When one side of the points is worn, the blade
can be turned and the other side used.
When both sides of the points are
worn, have them sharpened.
The saw blade is not reversible, thus
it must only be used from one side.
8.1.2 Replacing 3-point blade,
saw blade (if permitted)
The blade must never be repaired,
but must be replaced as soon as
signs of breaking are noted or the
sharpening limit is exceeded.
Blades displaying the code indicated
on the Technical Data table should
be used on this machine.
Given product evolution, the above
mentioned blades may be replaced in time
with others having similar interchangeability
and operating safety features.
8.2 REPLACING THE CUTTING
LINE HEAD
Follow the sequence indicated in fig. 24.
8.3 SHARPENING THE LINE
CUTTING KNIFE
• Remove the line cutting knife (Fig.
25 A) from the guard (Fig. 25.B), by
loosening the screws (Fig. 25.C).
