23 Inspection and Maintenance
Proper maintenance of the lawn mower includes the
following activities:
► Inspecting the mowing blade periodically and replacing it
or having it replaced by an authorized STIHL servicing
dealer.
► Periodically sharpening the mowing blade or having it
sharpened and balanced by an authorized STIHL
servicing dealer.
► Having worn, missing or damaged safety labels replaced
by an authorized STIHL servicing dealer.
If you make a warranty claim for a component which has not
been serviced or maintained properly, coverage may be
denied.

23.2 Inspecting the Mowing Blade

WARNING
Never use a dull or damaged mowing blade. Working with a
dull blade leads to increased vibration, unsatisfactory cutting
results and increased wear, in particular if you use the lawn
mower on sandy ground or use it frequently under dry
conditions. A damaged mowing blade may vibrate, crack,
break or come off the lawn mower, which may result in
serious or fatal injury or property damage. Make sure the
mowing blade is sharp and in good condition before starting
work.
WARNING
The mowing blade has sharp edges. If it contacts your flesh,
it may cut you, even if it is not moving. Always wear heavy-
duty work gloves when inspecting or otherwise handling the
mowing blade, @ 5.5.
To inspect the mowing blade:
► Switch off the lawn mower, @ 15.2.
► Remove the fuse key and battery, @ 13.2 and @ 14.2.
► Place the lawn mower on a flat surface.
► Set the cutting height to position 6, @ 18.1.
► Fold down the handle, @ 12.2.
► Stand the mower on end.

► Use a caliper to check the blade thickness. Blade
thickness must be at least a = 0.05 in. (2.0 mm) at its
narrowest point.
► Use a caliper to check the blade width. Blade width must
be at least b = 1 in. (45 mm) at its narrowest point.
► Replace the mowing blade if the measured blade
thickness and width are outside the permissible limits.
► Check the sharpening angle. Sharpen the mowing blade,
if the sharpening angle is not c = 30°.

23.3 Sharpening and Balancing the Mowing Blade

WARNING
Never use a dull or damaged mowing blade. Working with a
dull blade leads to increased physical strain, increased
vibration load, unsatisfactory cutting results and increased
wear, which can result in loss of control and injury to the
operator or bystanders. A damaged mowing blade may
vibrate, crack, break or come off the lawn mower, which may
result in serious or fatal injury or property damage. Make
sure the mowing blade is sharp and in good condition before
starting work.
WARNING
An improperly balanced mowing blade can increase the risk
severe personal injury or death. STIHL recommends having
your mowing blade sharpened and balanced by an
authorized STIHL servicing dealer to reduce the risk of
severe or fatal injury.
