1. Model Name
AR-203E/5420/208D/208S, AL-2020/2030/2040/2040CS/2050CS
2. Symptom
The ribs on the side door inner frame serve to limit the sideways motion of the PS
upper roller in the side door inner frame section. When continuing to use the machine,
the ribs on the side door inner frame is whittled because the PS upper roller strikes
them, and the whittled powders enter between PS driven shaft and PS upper roller; it
may cause creaking noise.
3. Description
To prevent the ribs on the side door inner frame from being whittled, 8 rim guide
sheets have been added to them which the PS upper roller strikes.
If creaking noise occurs in the market, the whittled powders may have already been
generated. In this case, it may not be possible to eliminate abnormal noise by attaching
the rib guide sheets.
Detach the PS upper roller and clean the PS driven shaft to remove the whittled
powders. Then attach the rib guide sheets.
