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.
File correctly
NSelect sharpening tools according to chain pitch.
NClamp the bar in a vise if necessary.
NLock the chain – push hand guard forward.
NTo rotate the chain – pull hand guard against handle to disengage the chain brake On models with Quickstop Plus, also press down the throttle trigger lockout lever.
NSharpen the chain frequently, take away as little metal as possible – two or three strokes of the file are usually enough.

NHold 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.
NAlways file from the inside to the outside of the cutter.
NThe file only sharpens on the forward stroke – lift the file off the cutter on the backstroke.
NAvoid touching the tie straps and drive links with the file.
NRotate the file at regular intervals while filing to avoid
NUse a piece of hardwood to remove burrs from the cutting edge.
NCheck angles with the filing gauge. All cutters must be the same length.
If the cutters are not the same length, they will have different heights. This makes the chain run roughly and can cause it to break.
NFind the shortest cutter and then file all other cutters back to the same length. It is best to have this work done in the workshop on an electric grinder.
Depth gauge setting

The depth gauge determines the height at which the cutter enters the wood and thus the thickness of the chip removed.
aSpecified distance or setting between depth gauge and cutting edge.
This setting may be increased by
0.2mm (0.008") for cutting softwood in the mild weather season – no frost.
