Mowing blade
maintenance
CAUTION
Risk of injury!
A worn blade may break off
and cause serious injuries.
The instructions for blade
maintenance must therefore
always be observed.
Blades are subjected to
differing degrees of wear
depending on the location
and duration of use. If you
use the mower 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.
Always replace the blade
fastening screw (27),
retaining washer (29) when
replacing the mowing blade.
CAUTION
Risk of injury!
If you do not have the
necessary expertise or
auxiliary equipment, please
always contact a specialist
dealer. (VIKING
recommends VIKING
specialist dealers).
VIKING recommends the
use of original VIKING
spare parts.
Maintenance interval:
Before each use
Tilt the mower upwards into
the cleaning position.
26= Clean the mowing blade
and check it for damage
(notches or cracks) and
wear; replace if
necessary.
Wear limits:
The blade thickness must be
at least 2mmat any point.
(Check using slide calliper).
The blades may not be
ground back by more than
5mmduring sharpening.
When inspecting, place a
33= ruler against the front
blade edge and check for
wear.
CAUTION
If the supplied standard
blade is not installed in the
lawn mower, but e.g. the
mulching blade, which is
available as a special
accessory, different wear
limits apply.
