Husqvarna Chainsaw Chain - 15" X-Cut Sp33G Semi-Chisel 0.325" 1.3mm

The primary advantage is its combination of exceptional and long-lasting sharpness, high cutting efficiency, and enhanced durability, which together improve user productivity and reduce maintenance.

This chain is designed for Husqvarna models 545, 550XP Mark II, and 550XP G Mark II, when fitted with a 15-inch bar.

'.325" pitch' refers to the distance between the drive links (3 links per inch), and '1.3 mm gauge' refers to the thickness of the drive link that sits in the guide bar groove. These measurements are critical for chain and bar compatibility.

Yes, the X-CUT SP33G features a bumper drive link design for enhanced kickback reduction, contributing to safer operation.

Chain tension should be checked before each use and frequently during operation, especially when the chain is new or when working in varying temperatures, as chains can stretch or contract.

While technically it might fit if the pitch, gauge, and bar length match, it is specifically developed and optimized for the listed Husqvarna models. Using it on incompatible saws may lead to poor performance, premature wear, or safety hazards.

Use a round file with a 5/32" diameter for the .325" pitch chain. Always use a file guide to maintain the correct depth and angle of the cutters for optimal performance.

Check and adjust chain tension according to your chainsaw manual. Ensure the chain is correctly seated on the sprocket and bar.

The chain may be dull. Sharpen the cutters with the correct file size and angle. Also, check for proper chain tension and lubrication.

Check for damaged or unevenly worn cutters. Ensure the chain is properly tensioned and that the guide bar is in good condition and not warped.

Ensure the chain is new and properly seated. If excessive stretching continues, inspect for manufacturing defects or premature wear. Ensure proper lubrication and tension.
