• Adjust the clearance of the moving blade to ensure that the cut is clean and accurate. The gap
between the blades should be checked regularly as friction wears the blades where they come into
contact. The nut is designed to block its position with the central screw which allows adjustments if
needed.
• To adjust the blade to the appropriate distance of about 0.03 mm loosen the central screw of the nut
by turning it clockwise, turn the nut clockwise to reduce the clearance and counterclockwise to
increase the clearance. When the adjustment is complete, hold the nut locked in place and tighten
the central screw by turning it counterclockwise
15.2. Greasing of the blades
The greasing of the blades has sto be repeated each 2-3 working days to guarantee the correct
performance of the tool and to avoid the seize of the blades.
• Open the blades of the pruner.
• Turn off the tool and remove the battery.
• Apply the grease between the moving blade and the fix blade (see the picture below).
• Put together the battery and the tool.
• Turn on the pruner and pull the trigger sometimes to get the grease through the blades.
• Clean the blades from the grease leftover.
15.3. Disassembly and grease
General maintenance, cleaning, lubrication and blade replacement requires some disassembly and
assembly of your pruner.
The cover is fixed to the pruner by 2 screws. The adjusting nut is fixed with a central screw.
By removing the cover, the central screw, the adjusting nut, the bearing and the hexagonal bolt, you can
access, maintain, clean, lubricate and replace the blades when needed.
It is recommended to grease the gears each 3-4 working days to guarantee the correct operating life of
the tool.
