place in the cleaning position as shown.
Notes on cleaning:
● Clean off dirt using little water, with a
brush or with a cloth. In particular, also
clean the mowing blade. Never spray
water on motor components, seals,
bearing points or electrical components
such as batteries or switches.
● First, remove accumulated clipping
deposits using a stick.
● Remove dirt from the air slots on the
motor and the air ducts on the bottom of
the machine to ensure that the motor is
adequately cooled.
● If necessary, use a special cleaner
(e.g. STIHL special cleaner).

13.6 Checking blade wear
Maintenance interval:
Before each use.
Risk of injury!
Blades are subjected to differing
degrees of wear depending on the
location and duration of use. If you
use the machine on sandy ground
or use it frequently under dry
conditions, the blade will be
subjected to greater loads and will
wear more quickly than the
average.
A worn blade may break off and
cause serious injuries. The
instructions for blade maintenance
must therefore always be
observed.
Checking procedure
● Place the machine in the cleaning
position. (
13.2)
● Clean the blade (1) and check it for
damage (notches or cracks).
● Use a slide calliper (2) to measure the
blade thickness (A) at several points.
● Measure the permissible grinding (B).
Place a ruler (3) against the front blade
edge as shown for this purpose.
Wear limits
The blade thickness (A) must be at least
2 mm at any point. The most important
points are marked in the illustration.
The cutting edges must not be ground
back by more than 5 mm – distance (B)
(permissible grinding) during sharpening.
13.7 Removing and installing the
18
mowing blade
Risk of injury!
Always wear gloves.
The mowing blade must
be replaced if notches or
cracks are detected or if a wear
limit is reached (
Removing
● Hold the mowing blade (1) and loosen
the blade fastening screw (2).
● Remove the blade fastening screw (2),
retaining washer (3) and mowing
blade (1).
Installing
