• Remove the blade shaft from the machine to grind blades (see annex 3).
• For safety’s sake, firmly clamp the blade shaft (i.e. In-between a bench vice) and ensure that
this cannot twist, move or fall unexpectedly during maintenance and, thus, injure someone.
For your information:
The blades do not have to be disassembled for Sharpening.
Use for this a small angle grinder equipped with a grinding
disc suitable for steel.
Caution:
Lit sparks will fly around when Sharpening the blades. They may start a fire.
Bear this in mind when selecting the work site. Never grind blades near fuel or
lightly flammable products. Always have available a fire extinguishing resource
in the immediate vicinity.

As described in “read § 11.3.2 Routine check of the blades” on page

these two features can be realised.
