MAINTENANCE
Dismantling the cutting unit
The cutting unit can be released from the machine
for cleaning or checking of the blades and screws.
Dismantle the cutting unit as follows:
1. Dismantle the front hood as described on page
18.
2. Dismantle the pull-rod (1). A tool can be used
when the needle spring is removed to
carefully
bend out the pull-rod from its holder.
3. Relieve the tensioning pulley (2) by disconnect-
ing the spring (3).
4. Fold the lock plate (5) forwards and press down
the front edge of the unit so that it releases from
the unit frame (4).
5. Push the unit backwards and dismantle the drive
belt, and then pull the unit forwards so that the
back end releases from the unit frame.
Fitting of the cutting unit takes place in the reverse
order to dismantling.
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,
(45–60 Nm, 33–44 lb.ft)
IMPORTANT INFORMATION
Replacing or sharpening the blades
should be conducted by an authorised
service workshop.
IMPORTANT INFORMATION
The Bioclip unit should always have the
blades in the relative positions shown in
the diagram, with a 90° angle between the
blades. Otherwise the blades can go
against each other and cause serious
damage to the unit.
WARNING!
Wear protective glasses when dis-
mantling the cutting unit. The spring
which tensions up the belt can go
off and cause personal injury.
