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 automat‐

ically 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

689BA025 KN

► Use a file holder
A file holder must be used for manual resharpen‐

ing (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.

21.5

For checking angles

001BA203 KN

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.

21.6

File correctly

► Select sharpening tools according to chain

pitch.

► 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.

► Clamp the bar in a vise if necessary.

► Sharpen the chain frequently, take away as lit‐

tle metal as possible – two or three strokes of

the file are usually enough.

689BA018 KN

90°

689BA043 KN

► 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.

► Always file from the inside to the outside of the

cutter.

► The file only sharpens on the forward stroke –

lift the file off the cutter on the backstroke.

► Avoid touching the tie straps and drive links

with the file.

► Rotate the file at regular intervals while filing to

avoid one-sided wear.

► Use a piece of hardwood to remove burrs from

the cutting edge.

► Check angles with the filing gauge.
