MAINTENANCE
Checking the blades
To achieve the best mowing results it is important
that the blades are undamaged and well-sharpened.
Check that the blades’ attachment screws are tight.
IMPORTANT INFORMATION
Replacing or sharpening the blades
should be conducted by an authorised
service workshop.
IMPORTANT INFORMATION
The blades of the BioClip unit should
always be spaced as shown in the diagram
at 90º intervals. If not, the blades may
collide and cause damage to the cutting
unit.
The blades should be balanced after sharpening.
Damaged blades should be replaced when hitting
obstacles that result in a breakdown. Let the
servicing dealer judge whether the blade can be
repaired/ground or must be discarded.
Replacing the break-pin (BioClip)
The blades are fitted with a break-pin to protect the
BioClip unit and its drive when colliding with
obstacles. A domed, spring friction washer is fitted to
each blade bolt. The washer must always be
replaced with a new washer when replacing the
break-pin. Otherwise the break-pin can break
causing the blades to collide.
Only use original spare parts. A set containing a
blade, break-pin and friction washer can be
purchased from your dealer.

in the service position”.
2. Remove the blade (2A) by removing the blade
