Description
Overview:
This Throttle Lock is a Genuine Husqvarna part for petrol chainsaws, engineered to hold a steady throttle position for safe starting and controlled cutting. Precision-moulded from durable polymer to resist fuel, oil, vibration, and temperature changes, it interfaces with the trigger mechanism to deliver consistent engine speed and prevent unwanted movement. Designed specifically for the Husqvarna 261 and 262XP, it restores the correct operation of the throttle locking function when the original component is worn, cracked, or missing. As an OEM-matched replacement (503 50 93-02), it fits accurately without modification and supports reliable performance in professional and domestic use.
