14.4 Chain sharpening:
Chain sharpening requires special tools to ensure that cutters are sharpened at the correct
angle and depth. For non-experienced users of the chain saw, we recommend to have
thechain sharpened by a specialist in any authorised service.
Warning: when having wrong sharpened chain, there may occur a higher
danger of kickback.
▪ To sharpen the saw chain, use the suitable sharpening tools:
− round chain file
− file leading
− chain measuring calibre.
These tools can be bought in any specialsed 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 4mm. 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
Warning: a sharp chain produces welldefined 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.
WARNING: Proper adjustment of the depth gauge is as important as proper
sharpening of the chain.
14.5 Guide bar
The bar should be reversed every 8 working hours to ensure uniform wear. Keep the bar
groove and lubrication hole clean using a bar groove cleaner. Check the bar rails frequently for
wear and, if necessary,
Warning: never mount a new chain on a worn sprocket or self-aligning ring.
Bar wear - turn guide bar frequently at regular intervals (for example, after 8 hours of use), to
ensure even wear on top and bottom of bar.
Oil passages - oil passages on the bar should be cleaned to ensure proper lubrication of the
bar and chain during operation.
