Introduction
The trigger for the Nerf Dart Tag Swarmfire sometimes malfunctions. This is typically caused by an issue with the trigger spring. Issues can include the spring wearing out or being installed incorrectly. This guide will walk you through how to disassemble the blaster, replace the spring, and reassemble the blaster so the trigger works again.
Tools
-
-
Place the blaster on its side with the handle to the right and loosen all screws so the shell can be opened. (Not all screws are visible in the provided pictures.)
-
Avoid the fake plastic screw, which is merely decorative.
-
-
-
Gently remove the yellow and grey shell pieces from the blaster to display the blaster's motherboards and motor.
-
-
-
Locate the orange trigger (dark blue if it's the newer version).
-
Slide the trigger out of place and check the spring. It should be corrosion-free and fitted to the knob on the back of the trigger.
-
-
-
If it is damaged, pull the spring off the trigger, then push the replacement spring onto the knob so it catches and doesn't fall off.
-
If the spring is not damaged, it is possible the spring was installed incorrectly. Ensure the spring is attached to the knob so it sticks straight out and doesn't fall off.
-
-
-
Put the trigger back into place with the trigger spring pressed into the small slot behind the trigger well. It should fit into place straight with slight compression.
-
To reassemble the blaster, replace the shell pieces from innermost to outer and gently tighten the screws until they give a little resistance. If the screws give significant resistance initially, back them up and loosely turn them until they screw in with little effort.
