Genuine CleanMax CPU-3N foot pedal spring (part# B020-0400) – the return spring that snaps the height-adjust pedal back and holds it in each setting. Fits the CPU-3N and CPU-3QD nozzle. In stock, ships from Crystal, MN. Call 763-535-0770.
The CleanMax CPU-3N foot pedal spring (part# B020-0400) is the return spring behind the height-adjust foot pedal. It provides the tension that snaps the pedal back after each press and holds the pedal firmly in the height position the operator selects, which is what gives the linkage its positive, repeatable feel.
Compatible Models
- CleanMax CPU-3N commercial upright
- CleanMax CPU-3QD (shares the same nozzle assembly)
Replace the spring when the pedal has gone soft, slow to return, or will not hold a setting and drifts between heights. A stretched, weak or broken spring is the single most common reason a nozzle pedal feels mushy or sticks, and it is an inexpensive part to renew. Because the symptom overlaps with a worn pedal or shaft, inspect the spring first – it is often the whole fix.
The spring works in the pedal frame (B020-0100B) alongside the pedal (54-016) and shaft (B020-0300). When you fit a new spring, confirm the pedal clicks crisply through every height detent and returns fully on its own before the machine goes back into service.
