Description
Overview:
The Starting Throttle Lock for Stihl HS86, BG45 is a genuine Stihl component that holds the fast-idle position during cold start, so the engine can fire and warm up without manual throttle input. This small but vital part fits into the trigger/lock mechanism on a range of Stihl handheld machines, including hedge trimmers and blowers. Made from durable plastic for long service life, it is designed for precise engagement with the throttle linkage and housing. As a Genuine Part (OEM), it matches original dimensions for reliable fit and function. OEM Part Number: 4228 182 9300. Ideal for replacing a worn or cracked lock that causes poor starting or requires the trigger to be held, helping restore consistent start-up behaviour on machines such as the HS86 and BG45.
Key Features:
- Genuine Stihl OEM part for assured fit and performance
- Controls and holds the fast-idle/throttle position during starting
- Durable plastic construction resists wear and deformation
- Accurate moulding ensures smooth engagement with the trigger assembly
- Quick, straightforward fitting with standard hand tools
- Helps improve cold-start consistency and reduce stalling on ignition
- Restores original operation when the existing lock is worn or broken
- Broad compatibility across selected Stihl hedge trimmers, blowers, vacs, and the BT45 drill
Typical Applications:
Used during routine servicing or repairs when start-up becomes unreliable, the lock replaces damaged or fatigued parts in the throttle trigger assembly. Common on hedge trimmers, leaf blowers, shredder vacs, and the BT45 drill, it helps maintain the correct fast-idle position for easier cold starts and smoother warm-up, reducing downtime on site or in the garden.
