SEBO Air Channel Cover with Suction Control Parts for 300 and 350 Mechanical Uprights

Two jobs sit in one molding here. Part 50308ER closes off the air channel on the SEBO 300 Mechanical and the SEBO 350 Mechanical and also carries the suction controls that ride on it, so the kit arrives with a dial wheel, its spring, a lever and the push-button knob all fitted to the panel. SEBO records the cover itself at position 106 of the 300 350 Mechanical parts diagram.

A hairline crack anywhere along this cover bleeds air out of the channel before it ever reaches the nozzle, which presents as a machine that has quietly lost pull for no visible reason. It is a fault that hides well, because the bag is clean, the filters are new, and nothing looks wrong from the outside. A dial that spins without changing anything, or a knob that no longer returns when released, points instead at the control pieces riding on the panel. Ordering the assembly complete covers both faults in a single fitting.

Work through the rest of the airpath before blaming the cover. Hose 5040SB, connection tube 50105HG, fitting 50131HG and cleaning wand 50165HG are the other places a leak or a blockage hides on these uprights, and a bag housing that has distorted, 50200GS, will mimic the same symptom.
