Depth
gauges
The depth gauge determines the height at which the cutter
enters the wood and thus
the
thickness of the chip remo-
ved. The cutting capacity and life
of
a saw chain are there-
fore influenced by the distance between the depth gauge
and the cutting edge,
i.
e.
the depth gauge setting. This
setting varies according to chain
p~ch
and must be chec-
ked with the appropriate filing gauge.
The best cutting
resu~
are obtained with the settings li-
sted in the table. However, the depth gauge setting may
be increased by 0.2 mm for cutting scftwood in mild weat-
her conditions.
Since the depth gauge setting is reduced when the cutter
is sharpened,
its height must be checked and lowered if
necessary. If
iIle
depth gauge projects from the filing
gauge,
itmust be·filed down level with the gauge using a
flat or triangular file. The contour
of
the depth gauge must
alsc be rounded off on Rapid chain.
In
the case
of
Topic
chains the depth gauge should
be
rounded off in line with
the stamped markings.
General chain maintenance
Chain maintenance begins as soon as the chain is fitted
on the bar and sprocket. The essential points
are
correct
chain
tension
and
ample
lubrication
.
See
aisc "Guide
Bar,
Chain and Sprocket".
Clean the chain thoroughly in gascline after sharpening to
remove filings or grinding dust. Then lubricate the chain by
