Description
Overview:
This throttle lock is a genuine Husqvarna spare part designed for selected Husqvarna chainsaws, including the 242 and 246. It forms part of the handle/trigger assembly and holds the throttle in a set position when required, helping to keep engine speed stable and reducing the chance of unintentional throttle closure during use. Made from durable polymer suited to outdoor power equipment, it resists vibration, fuel and oil exposure, and everyday wear. As a direct replacement for OEM No. 503 41 39-02, it restores correct function where the original latch is worn, broken, or missing. The precise moulding and OEM specification ensure reliable engagement with the throttle mechanism, supporting safe starting and controlled operation across varied cutting tasks.
Key Features:
- Genuine Husqvarna part for correct fit and dependable performance (OEM 503 41 39-02)
- Durable polymer construction designed to withstand vibration, fuel and oil
- Maintains a set throttle position for consistent engine speed and smoother work
- Helps prevent unintended throttle changes for better control and safety
- Direct-fit replacement; no modifications required on compatible models
- Supports reliable starting procedures and fast-idle hold where applicable
- Stable engagement with trigger assembly for repeatable operation over time
- Colour and form matched to OEM specification for easy identification during servicing
Typical Applications:
Used during routine maintenance or repair of Husqvarna chainsaws when the throttle will not hold position, the fast-idle lock fails to engage, or there is excessive play in the trigger latch. Suitable for workshop overhauls, site repairs, and preventative maintenance to reduce downtime and improve control during felling, logging, pruning, and general cutting.
