Adjusting screw, which tightens the brake cable 2 to the cutter frame Pict.11 , needs to be screwed in against the direction of the arrow
(towards the frame), so that the axial clearance of the brake cable in the adjusting screw is 1 mm. Check the automatic brake function. If
complete tightening the screw
2 does not offer adequate brake effect, tighten the adjusting screw of the brake cable on the handlebars so
that the axial clearance of the brake cable in the adjusting screw is 1 mm. Check the automatic brake function
