13.8 Sharpening the mowing blade

If you do not have the necessary expertise
or auxiliary equipment, you should have
the blade sharpened by a specialist dealer
(STIHL recommends STIHL specialist
dealers).
Operation of the machine is impaired in the
case of an incorrectly sharpened mowing
blade (incorrect sharpening angle,
imbalance, etc.), the cutting performance
(battery running time) may be reduced and
the noise emissions increased.
Sharpening instructions
● Remove the mowing blade. (
● Cool the mowing blade during
sharpening, e.g. with water.
The blade must not be allowed to
display blue colouring, as this would
reduce its cutting quality.
● Sharpen blades evenly to prevent
vibration due to imbalance.
● Observe a sharpening angle of 30°.
● Observe the wear limits. (
