4.11 Suction port
4.11.1 Adjust suction port
Due to the suction power of the fan, the dirt is collected by the suction port
26 and taken into the dirt hopper through the suction pipe 26A.
Clearance of the sealing strip 26B around the suction port has to amount
to 10mm. Before ground clearance adjustment, loosen the caster roller
holder 26C. Immediately replace any defective sealing, even those at the
suction port flap 26D, since otherwise suction performance reduces signi-
ficantly.
