Description
Throttle trigger spring fits 4500 (45CC), 5200 (52CC) and 5800 (58CC) Chinese chainsaws. The throttle trigger spring is the small return spring within the trigger assembly that pushes the throttle trigger back to the idle position after the operator releases it. When the spring is fatigued, deformed or broken, the trigger may stick in the open position or fail to return to idle, making the chainsaw unsafe to operate. Replacing a worn trigger spring restores correct throttle response and safe idle return.

- Plantiflex
