222. Check the sealing strips
of the suction mouth at regular
intervals. Maintenance intervals according to maintenance plan,
see page 167.
Immediately replace defective seals, also on the coarse material

15 +0/-2 mm at the front and at the rear respectively. The
coarse material flap is set to a ground clearance of 20 +0/-2 mm.
