PowrLiner part 424-202 is an actuator lever designed for use on ProMark II and a wide range of PowrLiner sprayers. This lever provides the mechanical interface for actuating control valves, pressure relief systems, or spray gun triggers, ensuring precise operator control. Replacing a worn, bent, or broken actuator lever restores smooth, reliable operation and prevents intermittent or failed actuation.

The PowrLiner 424-202 Actuator Lever is a genuine OEM component used to control critical functions on ProMark II and a broad range of PowrLiner sprayers. Depending on the model, this lever may operate the spray gun trigger, pressure relief valve, or other mechanical actuators, providing the operator with precise, reliable control.
Repeated use, exposure to vibration, or accidental impact can cause the actuator lever to become bent, worn, or cracked. A damaged lever can lead to inconsistent actuation, failure to engage or disengage the spray function, or unsafe operation. Replacing the lever with the correct 424‑202 part restores smooth mechanical control and ensures reliable performance.
| Spray control | Activates or deactivates the spray gun or material flow |
|---|---|
| Pressure relief | Engages the pressure dump valve for safe system depressurization |
| Operator interface | Provides a tactile, ergonomic point of control |
| Bent / deformed | Lever no longer moves smoothly or reaches full travel |
|---|---|
| Worn pivot point | Excessive play or looseness at the mounting point |
| Cracked / broken | Visible cracks or complete failure of the lever |
| Corroded / seized | Lever is difficult to move due to rust or corrosion |

When replacing the actuator lever, it is common to inspect associated components that may have contributed to lever wear or may be worn themselves.
The pin or bushing that the lever pivots on can wear, causing slop and uneven actuation.
The lever may actuate a valve or electrical switch; inspect these for proper operation.
If the lever returns to a neutral position, ensure the spring is intact and properly tensioned.
