12.6 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 average. A
worn blade may break off and
cause serious injuries. The
instructions for blade maintenance
must therefore always be observed.
● Set the lawn mower onto its back into
cleaning position. (
12.2)
● Clean the mowing blade (1).
● Use a slide calliper to measure the
blade thickness A at 5 points at least.
In particular, minimum thickness must
also be ensured in the area of the blade
wings.
● Check the blade width B in the area
marked in grey X at least 3 points
using a slide calliper.
Wear limits:
Blade thickness A: > 1,6 mm
Blade width B: > 56 mm
The blade must be replaced,
– if it is damaged (notches, cracks),
– if the measured values are achieved at
one or more points or are outside the
permissible limits.
12.7 Removing and installing
mowing blade
20
Risk of injury!
Always wear suitable protective
gloves when working on the
mowing blade.
● Tilt the lawn mower onto its side when
working on the mowing blade. (
1 Removing:
● Hold the mowing blade (1) with one
hand.
● Remove the blade fastening screw (2)
together with the coupler (3) and
mowing blade (1).
2 Installing:
Risk of injury!
Check condition of the mowing
blade (damage, wear) before
installing, replace if necessary.
(
12.6)
Only install the mowing blade as
shown, with the curved wings
pointing upwards (towards the
machine). Observe the specified
torque when tightening the blade
fastening screw, as the secure
attachment of the cutting tool
depends on this. Additionally
secure the blade fastening screw
with Loctite 243.
Renew the blade fastening screw
and coupler each time the blade is
replaced.
● Clean the blade contact surface and
blade bushing.
