The cutting blade (14a) can become blunt over time.
• If you notice this, loosen the screws securing the
cutting blade (14a) to the shield (14).
• Then fasten the cutting blade (14a) in a bench vice.
• Grind the cutting edge of the cutting blade (14a) us-
ing a flat file and make sure to maintain the angle of
the cutting edge.

flat file and make sure to maintain the angle of the
cutting edge. (~25°) Only file in one direction.
• The cutting blade (15) must be replaced after
sharpening them five times at the latest.
Replace the cutting blade (15) if the cutting edge is
heavily worn or broken.

ed pruner (21):
1 = the opening for the oil feed
2 = the oil channel
