The spark plug must be replaced with one with
the same characteristics whenever the elec-
trodes have burnt or the insulation has worn, and
in any case every 100 working hours.
5.7 LUBRICATION
IMPORTANT To preserve drive parts, we recom-
mend greasing the angle  gear and  flexible shaft 
every 15 hours of use.
ANGLE TRANSMISSION (Fig. 21a)
Lubricate with lithium-based grease.
Remove the screw (1) and put in the grease,
turning the shaft manually until grease emerges,
then replace the screw (1).
FLEXIBLE SHAFT (Fig. 21b)
Models SBC 645 KF - 653 KF:
Lubricate with lithium-based grease.
Unhook the hose (12) from the motor side,
extract the exible shaft (12 c) and apply grease

5.8 BLADE MAINTENANCE
5.8.1 Sharpening the 3 or 4-point blade
(Fig. 22)
WARNING! Use protective gloves. If
sharpening is done without removing the
blade, disconnect the spark plug cap.
Sharpening must be done taking account of the
type of blade and cutting edges, using a at le
and working all the points equally.
The references for correct sharpening are given
in Fig. 22:
A = Incorrect sharpening
B = Sharpening limits
C = Incorrect and unequal angles
IMPORTANT It is important to retain the correct
balance  after  sharpening.  For  safety  reasons, 
sharpening  and  balancing  should  be  done  by  a 
Specialised Centre with suitable skills and equip-
ment  for  the  job;  without  risking any  damage  to 
the blade which would make it unsafe when used.
3 or 4-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.
WARNING! The blade must never be re-
paired, but must be replaced as soon as
signs of breaking are noted or the sharpen-
ing limit is exceeded.
5.8.2 Sharpening the 3 or 4-point blade
Blades bearing the code indicated on the chart
on page 3 should be used on this machine.
Given product evolution, the above mentioned
blades may be replaced in time with others hav-
ing similar interchangeable and operating safety
features.

3. Turn the starter grip (1) clockwise until one of
the arrows is aligned with one of the two exit
holes (4) of the line.
