| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | Genuine OEM Titan control knob that mounts onto the pressure control potentiometer shaft, providing the operator interface for setting spray pressure. Supersedes the earlier 704-488A knob. |
| Function | Turns the potentiometer shaft that signals the motor controller to increase or decrease pump output. Provides tactile feedback with graduated markings and detents that allow the operator to set and repeat specific pressure levels. Also covers the control shaft and prevents dust, paint, and moisture from entering the electronics. |
| Compatible Titan Machines | Titan MultiFinish 440 (primary fit, confirmed in catalog); Titan Impact 440X; Titan Impact 640; Titan Impact 740; Titan Impact 840.

| OEM Part Number | 805-354 Control Knob (Replaces Titan 704-488A). |
| Replacement Indicators | Cracked, broken, or missing control knob; stripped bore causing the knob to spin freely on the shaft without turning the potentiometer; faded markings making it difficult to set repeatable pressure levels; missing knob requiring pliers to adjust pressure. |
| Related Parts Commonly Serviced Together | Potentiometer shaft (inspect for bending or damage); control board (check for loose mounting); face plate (replace if cracked or faded). |
| Common Problems Solved | Restores precise, tactile pressure adjustment; enables quick, accurate pressure changes; eliminates operator frustration from guessing at settings or using tools to adjust pressure. |
| Why Genuine OEM | Manufactured to OEM specifications for bore size, grip diameter, material composition, and marking layout. Ensures proper fit on the potentiometer shaft and reliable, repeatable pressure adjustment. |
Service guidance: Disconnect power before servicing. Remove the old knob by pulling it straight off the potentiometer shaft. Inspect the shaft for bending or damage and verify the control board is securely mounted. Align the new knob with the shaft flats and press firmly into place. Test pressure adjustment through the full range to confirm smooth operation.
