SHARPENING
TIGHTENING THE BLADE
This operation is essential because it determines the cutting quality and the service life of the blades, the
mechanical components and the endurance of the battery. Sharpening frequency depends of course on the
wood that is cut (hardness and diameter), the pruning rate and the sharpening tool (a special stone
09
is
provided). Therefore, during the first days of use, the condition of the blade cutting edge must be checked
regularly in order to maintain the edge by resharpening it little but often (a check every quarter of an hour
will quickly give you an idea of this frequency).
IT IS IMPORTANT TO REMOVE THE BURR FROM THE BLADE CUTTING EDGE AND TO PERFORM
THE FIRST SHARPENING OPERATION AFTER THE FIRST 15 MINUTES.
