Maintaining And Sharpening The Saw Chain - Stihl MS 362 C-M Instruction Manual

English
28 Maintaining and Sharpen‐
ing the Saw Chain
28.1 Sawing effortlessly with a prop‐
erly sharpened saw chain
A properly sharpened saw chain cuts through
wood effortlessly even with very little pushing.
Never use a dull or damaged saw chain – this
leads to increased physical strain, increased
vibration load, unsatisfactory cutting results and
increased wear.
► Clean the saw chain
► Check the saw chain for cracks and damaged
rivets
► Replace damaged or worn chain components
and adapt these parts to the remaining parts in
terms of shape and level of wear – rework
accordingly
Carbide-tipped (Duro) saw chains are especially
wear-resistant. For an optimal sharpening result,
STIHL recommends STIHL servicing dealers.
WARNING
Compliance with the angles and dimensions lis‐
ted below is absolutely necessary. An improperly
sharpened saw chain – especially depth gauges
that are too low – can lead to increased kickback
tendency of the chain saw – risk of injury!
28.2 Chain pitch
The chain pitch marking (a) is embossed in the
area of the depth gauge of each cutter.

28 Maintaining and Sharpening the Saw Chain

The diameter of file to be used depends on the
chain pitch – see table "Sharpening tools".
The angles of the cutter must be maintained dur‐
ing resharpening.
28.3 Sharpening and side plate
angles
A
B
A Sharpening angle
STIHL saw chains are sharpened with a 30°
sharpening angle. Ripping chains, which are
sharpened with a 10° sharpening angle, are
exceptions. Ripping chains have an X in the des‐
ignation.
B Side plate angle
The correct side plate angle results automatically
when the specified file holder and file diameter
are used.
Tooth shapes
Micro = semi-chisel tooth, e. g.,
63 PM3, 26 RM3, 36 RM
Super = full chisel tooth, e. g.,
63 PS3, 26 RS, 36 RS3
Ripping chain, e. g., 63 PMX,
36 RMX
The angles must be identical for all cutters in the
saw chain. Varying angles: Rough, uneven run‐
ning of the saw chain, increased wear – even to
the point of saw chain breakage.
