Hope one of you 488 MKII owners can help me with this...in the user manual under the pinch roller cleaning section, it says, "Push up the transport protection lever as illustrated. Press the PLAY key to engage the pinch roller and capstan shaft, while holding the protection lever up." Only problem is, the only illustration on the page doesn't show anything about a "protection lever." What are they talking about and how do I engage the pinch roller?
