Part 580-071 is a trigger assembly used to control the flow of material from the spray gun. It provides the mechanical action to open and close the fluid passage, allowing for precise on-demand spraying. This assembly restores proper control and reliable shut-off to compatible spray guns.
| Part Number | 580-071 |
|---|---|
| Part Description | Trigger Assembly |
| Compatibility | Airless LX 80 II |
| Condition | New |
The 580-071 trigger assembly is the user-operated mechanical component that controls the spray pattern. When pulled, it opens the fluid valve to allow material to flow to the tip; when released, it closes the valve to stop the flow.
A worn or damaged trigger assembly can cause leaking, difficulty controlling the spray, a trigger that sticks in the open or closed position, or excessive operator fatigue. Replacing it restores positive, reliable control over the spraying process.
| Flow Control | Mechanically opens and closes the fluid valve to start and stop material flow |
|---|---|
| Operator Interface | Provides the primary user control for precise on-demand spraying |
| Safety Function | Positive shut-off helps prevent accidental release of material when not in use |
| Leaking / Dripping | Gun continues to drip material after the trigger is released |
|---|---|
| Sticky or Stiff Action | Trigger does not move smoothly, requires excessive force, or sticks in position |
| Broken or Worn Parts | Visible cracks, excessive wear on the pivot points, or a broken trigger lever |
| Poor Control | Inability to achieve a consistent spray pattern due to erratic valve operation |
Part 580-071 is compatible with the following spray gun model. It is designed to fit the specific mechanical configuration of this gun. Always confirm fitment using the correct parts diagram for your specific unit.
| Gun Model | Component |
|---|---|
| Airless LX 80 II | Trigger Assembly |
Trigger assembly issues are often related to other wear components within the gun's fluid path. These parts are frequently inspected or replaced during a trigger service.
The needle, actuated by the trigger, seals against the seat. Wear on either part causes leaking.
Worn packing around the needle can cause external leaks and affect trigger smoothness.
A weak or broken spring will not return the trigger properly, causing poor shut-off.
