It is absolutely necessary to change the blade:
– When one of the wear markings (
1
) was
reached. Original blades are engraved with
wear markings (marking in form of a ball-
shaped imprint on the rear side of the
blade).
– When the thickness of the blade at the rear
edge of the vane (
2
) or at another point is
below 1 mm (exception: cutting edge).
Original blade
An original AS-blade is engraved with:
AS GXXXXXXXX or EXXXXX
This corresponds to the spare part number.
When using the device on sandy and abrasive
grounds, the wear at the blade is high. A spe-
cial blade was developed for these applications
(for abrasive ground blade, see accessories).
Checking engine brake
Check the function of the engine brake by
switching off the engine. The blade must come
to a standstill from full speed within less than
7 seconds. Contact an authorised service
centre if this is not the case.
