1.3.1 Selecting the cutting device
Choose the most suitable cutting device for the
job to be done, according to these general indi-
cations:
– the 3-point blade is suitable for cutting brush-
wood and small shrubs up to 2 cm in diameter;
– the 4-point blade is suitable for cutting tough
grass over large surfaces;
– the cutting line head can eliminate tall grass
and non-woody vegetation near fences, walls,
foundations, pavements, around trees, etc. or
completely clean a particular area of the gar-
den;
– the saw blade (if permitted) allows small
woody parts to be cut and small trees to be
felled.
Every cutting device must be fitted with a specif-
ic guard, as indicated by the following directions.
IMPORTANT The cutting devices are fastened
with a left-hand thread and therefore must be un-
screwed clockwise and screwed on anticlock-
wise. Remove all elements that may have been
assembled, which will be used in various con-
figurations, according to the cutting device used.
