Checking The Chain Sprocket; Maintaining And Sharpening The Saw Chain - Stihl MS 193 Notice D'emploi

Checking the Chain Sprocket

Disengage the chain brake: Pull the
N
hand guard toward the front handle.
Remove the chain sprocket cover,
N
chain and guide bar.
Replace the chain sprocket
after using two saw chains or
–
sooner
if the wear marks (arrows) on the
–
sprocket are deeper than approx.
0.5 mm since this would reduce the
life of the chain. You can use a
gauge (special accessory) to check
the depth of the wear marks.
It is best to use two saw chains in
rotation with one sprocket.

Maintaining and Sharpening
the Saw Chain
Sawing effortlessly with a properly
sharpened saw chain
A properly sharpened saw chain cuts
through wood effortlessly even with very
little pushing.
Never use a dull or damaged saw chain
– this leads to increased physical strain,
increased vibration load, unsatisfactory
cutting results and increased wear.

components and adapt these parts
to the remaining parts in terms of
shape and level of wear – rework

Carbide-tipped (Duro) saw chains are
especially wear-resistant. For an optimal
