Description
Overview:
The Trigger Interlock for Stihl HS45 (OEM Part No. 4228 182 0800) is a genuine Stihl safety component for HS45 hedge trimmers. Precision-moulded from durable, impact-resistant polymer, it sits in the handle assembly and blocks the throttle trigger until deliberately pressed, helping to prevent unintended activation. This part restores the correct safety function if your original lockout is worn, cracked, or missing, and it integrates cleanly with the factory throttle system. Built to OEM tolerances for reliable fit and action, it withstands regular handling, fuel splash, oil, vibration, and outdoor conditions. Suitable for professional users and DIY owners alike, it is a straightforward replacement that helps maintain safe, consistent operation on Stihl HS45 and HS 45 models.
