SYMPTOM
The [D1] lever (LEVER: ON-OFF: TRANSPORT BELT UNIT; P/N D1363864; circled in red below) may
break if is moved up and down 30+ times.
CAUSE
The screw [A] that secures the lever is too short, and cannot provide enough torque to keep the lever [B] in
place when the lever is moved many times. As a result, the lever comes loose, contacts the PTB unit [C],
and breaks.
