Description
Overview:
This genuine Stihl choke knob is a direct replacement for the start/choke control on HS82 and HS87 series petrol hedge trimmers, including HS82R and HS87R. Supplied under OEM number 4237 182 9501, it is moulded from durable, fuel‐resistant plastic in a high‐visibility orange finish. The knob interfaces with the choke/start shaft to set the correct position for cold starts, warm restarts and fast idle, helping the engine fire reliably and settle quickly. Its positive-grip profile is easy to operate, even with gloves. A worn, cracked or missing knob can make starting difficult and lead to incorrect choke settings; replacing it restores safe, precise control. Suitable for professional landscapers and domestic users maintaining Stihl hedge trimmers used daily or seasonally.
Key Features:
- Genuine Stihl part for assured compatibility and reliability
- OEM reference 4237 182 9501 for accurate identification
- High-impact, fuel and oil resistant polymer for long service life

- Simple, quick fit to minimise downtime in the workshop or on site

Restoring the choke/start control on Stihl HS82/HS87 hedge trimmers used for hedge cutting, topiary and maintenance work.
