WARNING!
Cutting blade (14) sharpening is the most important operations for ensuring the shear good working. A
well-sharpened blade will guarantee precise clean cuts, low battery (1) consumption and low wear of the
mechanical parts. It is recommended to carry out slight and frequent sharpening operations instead of
heavy and rare ones, in order not to modify the blade geometry.

6.1.3 Cutting blade adjustment

• Choose the SERVICE function by means of the selector (19)
• Tighten the nut (22) up to the point that the cutting blade (14) has no side play left
• Carry out some blade opening and closing cycles
• The nut (22) tightening is correct when the display shows 6/7 notches
• If the display shows more than 7 notches, the nut has to be loosen. The display indicates NO PASS.
WARNING!
When loosening the nut (22) it is suggested to give few slight hits to the blade pin (29) on the nut side to
create the right clearance among the components.

6.1.4 Cutting blade (14) replacement

The following operations shall be performed in the indicated order:
• Remove the screws (11) to open the blade replacement cover.

6.1.5 Shear cleaning

Clean the shear at least once a week carrying out the operations:
• Remove the front cover for the blade replacement
•
Remove any dirt by means of a brush and a cloth. Do not use any liquid for the cleaning operations.
•
Lubricate the moving parts by means of spray grease
•
Reassemble the front cover
The wood shavings of the cutting get mixed with the lubricant in the tool and create a sort of abrasive paste which
decreases the life span of the parts subject to wear-and-tear.
