▪ To sharpen the saw chain, use the suitable sharpening tools:
round chain file
file leading
chain measuring caliber.
These tools can be bought in any specialized stores.
▪ To gain well shaped sawdust particles, use sharp chain. If there appears wooden powder,
you must sharpen the saw chain.
Warning: all cutting teeth must be similarly long. Different length of the
teeth can cause rough run of the chain or its rupture, as well.
▪ Minimum length of the teeth must be 4 mm. If they are shorter, remove the saw chain.
▪ Angles, which the teeth are under, must be followed.
▪ To sharpen the chain basically, make 2 to 3 pulls of the file from the inside out.
Warning: after 3 to 4 of your sharpening of the cutting teeth, havve the saw
chain sharpened in any authorised service. They will sharpen the depth
limiter as well, which provides the distance.
Chain sharpening
The pitch of the chain (Fig. 21) depends on the model.
Sharpen the chain using protective gloves and a round file of ø4.8mm.
Always sharpen the cutters only with outward strokes (Fig. 22) observing the values given in
Fig. 21. After sharpening, the cutting links must all have the same width and length.
Warning: a sharp chain produces well-defined chips. When your chain
starts to produce sawdust, it is time to sharpen.
▪ After every 3-4 times the cutters have been sharpened you need to check the height of the
depth gauges and, if necessary, lower them using the flat file and template supplied
optional, then round off the front corner (Fig. 23).
WARNING: Proper adjustment of the depth gauge is as important as proper
sharpening of the chain.
