Chain Sharpening.
6.5.1.
Sharpening is necessary when;
6.5.1.1.
The sawdust looks like dust;
6.5.1.2.
Cutting becomes more difficult;
6.5.1.3.
The cut is not straight;
6.5.1.4.
The vibrations increase.
6.5.2.
An authorized service centre will sharpen the chain using the right tools to ensure minimum
removal of material and even sharpness on all the cutting edges.
6.5.3.
If you sharpen the chain yourself, use special round-section files with the right diameter
depending on the type of chain (see “Chain Maintenance Table”). You need a certain amount
of skill and experience to avoid damaging the cutting edges.
6.5.4.
Sharpen the chain as follows (Fig. 29):
6.5.4.1.
Secure the bar firmly, with the chain mounted, in a suitable vice.
6.5.4.2.
Tighten the chain if it is loose.
6.5.4.3.
Mount the file in the guide and then insert it I the tooth at a constant angle from the
cutting edge.
6.5.4.4.
Sharpen in a forward motion a few times and repeat this on all the cutting edges
facing the same way (right or left).
6.5.4.5.
To move the chain forward, use a screwdriver.
6.5.4.6.
Turn the bar over in the vice and repeat on all the other cutting edges.
6.5.4.7.
Check that the depth limiter tooth does not stick out farther than the inspection tool
and file any projecting parts with a flat file, rounding off the edges (Fig 29).
6.5.4.8.
After sharpening, remove all traces of filing, dust and lubricate the chain in an oil
bath. Replace the chain whenever;
6.5.4.8.1.
The length of the cutting edges decreases to 5 mm or less;
6.5.4.8.2.
There is too much play between the links and the rivets.
To ensure that the chain saw works safely and efficiently it is, essential that the
cutting components are well-sharpened. It is highly recommended to replace the
chain once it loses its ability to cut cleanly and safely. It is possible, however, to
sharpen the existing chain if the sharpening is carefully performed. Any work on
the chain and bar requires specific experience and tools.
