• By twisting the stud bolts (U) to the right, slide the cutting bar closer to the
rotor blade and thereby reduce the cutting gap. Increase the cutting gap by
twisting to the left.
• Tighten the screw (WS) and check the cutting gap. Repeat the process if
necessary.
• After adjusting the cutting bar, tighten the screw (W) firmly again to 7Nm.
• Finally re-assemble the right and left-hand cover on the device.
NB
Do not set the cutting gap to less than 0.3 mm. Contact between the cutting plates
and cutting bars can damage the mechanical components.
The tightening torque of the screw (W) must be 7Nm. This is necessary to
guarantee that the cutting bars are securely positioned.
