▪ 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 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, have the saw
chain sharpened in any authorized service. They will sharpen the depth
limiter as well, which provides the distance.
Chain sharpening
The pitch of the chain depends on the model.
▪ Sharpen the chain using protective gloves and a round file of ø5/32” (4mm).
▪ 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.
WARNING: Proper adjustment of the depth gauge is as important as proper
sharpening of the chain.
Warning: never mount a new chain on a worn sprocket or self-aligning ring.
13.3 Chain maintenance
A slack chain may jump off the bar and cause serious or even fatal injury.
Always remove the battery before any assembly, maintenance and/or
checking is done on the machine.
Chain tension (also see paragraph 10.1):
▪ The more you use a chain the longer it becomes. It is therefore important to adjust the
chain regularly to take up the slack.
