Engineering improvements
STIHL’s philosophy is to continually improve all of its products. As a result, engineering changes and improvements are made from time to time. If the operating characteristics or the appearance of your machine differ from those described in this manual, please contact your STIHL dealer for assistance.
To reduce the risk of personal injury, special safety precautions must be observed while operating the filing tool.
Read the operating instructions carefully and keep them in a safe place for later reference.
Always shut off the saw engine before working with the filing tool: Move Master Control lever / slide control or the separate stop switch to STOP or $. Electric saws: Disconnect plug from power supply.
Wear gloves.
It is absolutely essential to comply with the angles and dimensions specified in these instructions. If the saw chain is incorrectly sharpened – and in particular if the depth gauges are set too low – there is a risk of increased saw kickback and personal injury.
Observing the safety precautions and specifications in these instructions and the owner’s manual of the saw model on which the filing tool is mounted can help reduce the risk of injury and damage to the saw.
The STIHL filing tool can be used to sharpen all STIHL Oilomatic saw chains with the exception of square ground chains (RSL, RSLF, RSLH) and carbide­tipped chains (RD, RDS). Sharpening is effected with the guide bar and chain mounted on the saw.
For accurate results it is best to clamp the guide bar in a bench vise or, at the cutting site, in the STIHL bar vise (special accessory).
File correctly
Sharpen the chain frequently, take
away as little metal as possible – two or three strokes of the file are usually enough.
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.

Use a slide caliper or similar to find the shortest cutter. This is the master cutter for filing all other cutters.
If the master cutter is in the left-hand row of cutters, clamp the guide bar so that the bar nose points to the right. If the master cutter is in the right-hand row of cutters, the bar nose must point to the left.
: Place the filing tool on the guide bar.
: The clamping jaws (1) must face the
bar nose and be in line with top edge of rivet heads.
: Tighten down the wing screw (2).

: Use the adjusting screw (3) to
center the filing tool above the chain.
: Tighten the second clamping jaw
with the clamp screw (4) so that the chain can still be pulled along the bar with a screwdriver or suitable rod engaged in a cutter.
