Genuine CleanMax Nitro CMNR-QD black handle release button (part# B283-5100). Unlocks the handle to recline for cleaning. Call 763-535-0770.
The Nitro CMNR-QD Handle Release Button (part# B283-5100) is the black foot- or hand-operated button on the CleanMax Nitro commercial upright that unlocks the handle so it can recline from its upright storage position back to the cleaning angle. It is pressed every time the operator starts a pass, so it is a high-cycle control.

This is a genuine Tacony OEM part built for the CleanMax Nitro CMNR-QD. CleanMax shares many components across its commercial upright range, so if you run a related CleanMax commercial model, call 763-535-0770 and we will confirm fit before you order.
What the Nitro CMNR-QD Handle Release Button does
The release button disengages the handle lock so the operator can drop the handle to the reclined cleaning position and return it to vertical for storage and above-floor tool use. It works against a spring so the handle stays locked upright until the operator deliberately releases it — that lock is what keeps the machine standing on its own between passes. Constant pressing and the spring load make the button a wear item.
Signs the Nitro CMNR-QD Handle Release Button needs replacing
Replace the button if it is cracked or broken, sticks down, or no longer springs back, or if the handle will not release or will not lock upright reliably. A button that has to be worked several times to free the handle, or a handle that falls forward on its own, points to a failed release button or its spring.
Installation and fit
Unplug the machine and set the handle upright. Remove the fasteners around the release mechanism, replace the old button and spring with the new black button in the same orientation, reassemble, and test that the handle locks upright and releases with one press. Twin City Vacuum has sold and serviced CleanMax equipment since 1956, and every part is sourced directly from Tacony. Browse more CleanMax parts, or learn more at CleanMax.
