The Husqvarna 572 XP is a high-displacement 2-stroke petrol-driven professional chainsaw designed for intensive felling and cutting. Its power demands rigorous maintenance to ensure longevity. Here's the complete guide to getting the best from it.
The 2-stroke fuel mix: engine foundation
Like all professional Husqvarnas, the 572 XP runs on a 2-stroke petrol/oil blend.
- Recommended ratio: 1:50 with quality 2-stroke oil, that's 20 ml per litre.
- Use fresh petrol with low ethanol content.
- Prepare small quantities to avoid mix degradation.
| Petrol | 2-Stroke Oil (1:50) |
|---|---|
| 1 L | 20 ml |
| 5 L | 100 ml |
The precise ratio and oil approved for your 572 XP version are listed in the manufacturer's documentation, which the L'Atelier mechanic AI retrieves with full sourcing according to your machine's reference.
Chain tension and sharpening
Cutting efficiency depends directly on the chain.
- Tension: adjust when cold; the chain should follow the guide without sagging or binding.
- Sharpening: respect the pitch and gauge, using a round file of the correct diameter.
- Lower the depth limiters gradually to maintain bite without chattering.
A chain that smokes and cuts slowly isn't necessarily worn: it's often down to blunt sharpening or poor lubrication.
Air filter and starting system
The 572 XP features an effective air filter and Air Injection system that pre-separates dust.
| Component | Maintenance |
|---|---|
| Air filter | Regular cleaning, dry before refitting |
| Spark plug | Check gap, clean electrodes |
| Primer pump | Check for smooth operation and seal integrity |
Hard starting when warm first points to a clogged filter or a tired spark plug before suspecting the carburettor. The exact spark plug gap for your version is provided by the L'Atelier mechanic AI.
Guide bar and lubrication
- Rotate the guide bar at each refuel to distribute wear evenly.
- Clean the groove and lubrication channel.
- Check the automatic chain lubrication flow on a clear surface at fast idle.
A sprocket worn to a point will accelerate chain wear: inspect it each time you replace the chain.
