Chain maintenance
B
Sharpening
Never cut with a dull saw chain. A chain which does not cut
unless you press it hard against the wood is damaged, dull or
incorrectly filed. In order to file the chain correctly you need;
round file (A), file gauge (B), flat file (C) and a depth gauge tool
(D). By using the correct file size (see the table) and an file gauge
with a marked filing angle, it is easier to receive a good result.
NOTE! Check that the drive link does not have a too large play in
the bar groove. This can give an incorrect filing result. Always file
from the inside of the teeth and out. Then turn the saw and file on
the other side. In order to receive a straight cut in the wood, all
the teeth should be filed to the same length. If the chain is filed
regularly, only a few strokes are needed on every saw tooth. For
the best performance, every chain type has different cutting
angles, file sizes and filing depth (see the table).
/!\ WARNING! If a too small filing size is used or the file is kept
too deep in the cutting tooth, the chain will be dangerously
aggressive. This means that kick-back can occur.
Depth gauge
In order to receive the best performance and life time of the
chain, always keep the prescribed depth gauge setting.
/!\ WARNING ! A too big depth gauge makes the chain
dangerously aggressive. This means that kickback can occur.
The depth gauge of the cutting tooth is checked with a depth
gauge tool (measurement, see table).
NOTE! The chain should be filed before the depth gauge is
checked. An adjustment of the depth gauge is done with a flat file
Round off the corner of the depth gauge, afterwards.
