AirCraft Air Body Saw Service Kit Trigger & Pin (12-13) For AT0021 (AT0021-SK04)
At a Glance: Trigger lever and pin kit (Parts 12 & 13) for the AirCraft AT0021—brings back smooth control, proper engagement and dependable throttle response.
On an air body saw, control is everything. A trigger that’s bent, worn, loose, or sticking doesn’t just feel irritating—it can make the tool unpredictable and harder to use accurately. The trigger and its pivot pin take constant movement and vibration, and over time they can wear, distort, or get damaged during heavy-duty panel work. The AirCraft AT0021-SK04 Service Kit includes the trigger and pin components (Parts 12 & 13) from the AT0021 spares diagram. It’s the ideal replacement when your trigger action feels sloppy, doesn’t return cleanly, or you want to restore the tool to a tight, responsive feel for controlled cutting.
This kit replaces the trigger lever and pivot pin—the mechanical link that activates airflow control—helping restore proper engagement, smooth movement and predictable throttle response.

- Improved safety: Correct trigger action and return supports safer tool handling.
- Less downtime: Quick fix for common wear issues caused by constant vibration and heavy use.

Extra Information
- Compatible with: AirCraft AT0021 Air Body Saw.
- Recommended when you notice: loose trigger feel, sticking, poor return, or trigger/pin wear.
- While servicing, inspect the valve area for contamination—dusty oil residue can make triggers feel sticky even with good parts.
Pro Tip
- After fitting the trigger, ensure it moves freely through its full travel and returns cleanly. A tiny amount of pneumatic tool oil on the pivot point can help—avoid heavy grease that attracts dust.
