IMPORTANT INFORMATION
On a bioclip-deck the relative positioning
of the blades should always be as shown
in the diagram with an angle of 90°
between the blades. Otherwise, the
blades can go against each other and
damage the deck.
Fit the new belts in the following way:
• First, twist on the lower belt and then the upper
one.
• Check that the blades are positioned in
accordance with the diagram with 90° between
them, otherwise the belts should be adjusted.
When the blade bearing is loose, the belt can be
slipped over to the next gear.
• Tighten the nuts so that the bearings lie close to
the cutting cover, but so that they can be displa-
ced.

parellel strut.
