Cutting effortlessly with a 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.

N Clean the chain.

N Check the chain for cracks in the

links and damaged rivets.

N Replace any damaged or worn

parts of the chain and match the

new parts to the shape and size of

the original parts.

Carbide-tipped saw chains (Duro) are

particularly wear resistant. STIHL

recommends you have your chain

resharpened by a STIHL servicing

dealer.

WARNING

It is absolutely essential to comply with

the angles and dimensions specified

below. If the saw chain is incorrectly

sharpened – and in particular if the depth

gauge is set too low – there is an

increased risk of kickback, with resulting

risk of injury.

The saw chain cannot be locked in place

on the guide bar. Therefore, it is best to

remove the chain from the bar and

resharpen it on a workshop sharpening

tool (FG 2, HOS, USG).

Chain pitch

The chain pitch (a) is marked on the

depth gauge end of each cutter.

Select file diameter according to chain

pitch – see table “Sharpening Tools”.

You must observe certain angles when

resharpening the chain cutter.

Filing and side plate angles

A Filing angle

STIHL saw chains are sharpened to a

filing angle of 30°. Exceptions are

ripping chains with a filing angle of 10°.

Ripping chains have an X in their

designations.

B Side plate angle

The correct side plate angle is obtained

automatically if you use the prescribed

file holder and file diameter.

The angles must be the same on all

cutters. If the angles are uneven: Chain

will run roughly, not in a straight line,

wear quickly and finally break.

File holder

N Use a file holder

A file holder must be used for manual

resharpening (see table "Sharpening

Tools"). The correct filing angles are

marked on the file holder.
