IMPORTANT
We recommend you take your
machine to your Retailer for sharpening as he has
the required tools and suitable experience.
In order to sharpen the blades, it is recommended
to use a fine grain file and proceed as follows (Fig.

– Place the file (1) on the blade (2) at a 45° angle,
and proceed with upward strokes towards the
cutting edge.
– Make sure that you put pressure on the file only
when stroking upwards and raise it from the
blade when you move it back towards you.
– Only remove a smallest amount of material.
– Eliminate any burr with a grinding stone.
– Eliminate all grinding traces and lubricate the
blades before reassembling them.
