▪ 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).
Always sharpen the cutters only with outward strokes observing the values in Fig. 16. 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.
14.4 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 (optional). (fig. 17) check the bar rails
frequently for wear.
Warning: never mount a new chain on a worn sprocket or self-aligning ring.
Oil passages - oil passages on the bar should be cleaned to ensure proper lubrication of the bar
and chain during operation.
Note: the condition of the oil passages can be easily checked. If the passages
are clear, the chain will automatically give off a spray of oil within seconds
of starting the saw. Your saw is equipped with an automatic oiler system.
14.5 Chain maintenance
Chain tension:
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.
▪ The more you use a chain the longer it becomes. It is therefore important to adjust the
chain regularly to take up the slack.
