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.

Use only special saw chain sharpening

files. Other files have the wrong shape

and cut.

For checking angles

Use a STlHL filing gauge (special

accessory, see table "Sharpening

Tools"). This is a universal tool for

checking the filing and side plate angles,

depth gauge setting, cutter length and

groove depth. It also cleans the guide

bar groove and oil inlet holes.

File correctly

N Select sharpening tools according

to chain pitch.

N If you use an FG 2, HOS or USG

sharpener: Remove the chain from

the bar and sharpen according to

the instructions supplied with the

tool.

N Clamp the bar in a vise if necessary.

N Sharpen the chain frequently, take

away as little metal as possible –

two or three strokes of the file are

usually enough.

N Hold the file horizontally (at a right

angle to the side of the guide bar)

and file according to the angles

marked on the file holder. Rest the

file holder on the top plate and depth

gauge.

N Always file from the inside to the

outside of the cutter.

N The file only sharpens on the

forward stroke – lift the file off the

cutter on the backstroke.

N Avoid touching the tie straps and

drive links with the file.

N Rotate the file at regular intervals

while filing to avoid one-sided wear.

N Use a piece of hardwood to remove

burrs from the cutting edge.

N Check angles with the filing gauge.

All cutters must be the same length.
