Maintaining And Sharpening Saw Chain - Stihl MSE 220 Instruction Manual

Maintaining and
Sharpening Saw Chain
Correctly sharpened chain
A properly sharpened chain slices
through wood effortlessly and requires
very little feed pressure.
Do not work with a dull or damaged
chain as it will increase the physical
effort required, produce unsatisfactory
results and a higher rate of wear.
: Clean the chain.
: Check the chain for cracks or
damaged rivets.
: Replace any damaged or worn parts
of the chain and match the new
parts to the shape and size of the
original parts.
It is necessary to observe the
angles and dimensions specified
below. If the saw chain is
incorrectly sharpened – especially
if the depth gauges are too low –
there is an increased risk of
kickback and resulting danger of
injury.

The chain pitch (e.g. / ") is marked near
8
the depth gauge of each cutter.
Use only special saw chain files.
Other files have the wrong shape and
cut.
Select file diameter according to chain
pitch – see table "Sharpening Tools".
You must also observe the following
angles when resharpening the chain
cutters.

A = Filing angle
B = Side plate angle
Chain type
Rapid-Micro (RM)
