STIHL recommends you use only the following
original STIHL cutting blades:
Length Thickness Marking
200 mm 2.4 mm

Do not resharpen the blade.
► Replace the blade (1) if its length (A) is no lon‐
ger sufficient to maintain the necessary
ground clearance (B) and obtain the required
depth of cut (C).

To avoid out-of-balance:
► Have your dealer check the blade for out-of-
balance on a STIHL balancer (special acces‐
sory) – STIHL recommends an authorized
STIHL servicing dealer. If blade is out-of-bal‐
ance, fit a new one – see "Mounting the Cut‐
ting Blade".
