Description
Overview:
The Piston Lock Tool for Husqvarna Repairs (504 91 06-05) is a genuine Husqvarna OEM service tool made from durable metal. It threads directly into the spark plug hole to lock the piston in place, stopping the engine from turning while you loosen or tighten components. This makes clutch, flywheel and other threaded fastener work safer and more precise, with less chance of damage. Suitable for a wide range of Husqvarna petrol machines using two-stroke engines, such as chainsaws, brushcutters and clearing saws, it provides a reliable hold during routine maintenance and repair tasks. Built to Husqvarna standards, it offers consistent performance in workshop and field conditions and is a practical choice for both professional technicians and DIY users maintaining their Husqvarna equipment.
