The Husqvarna Special Bar (MPN 578400172) is an essential component designed specifically for arborists and homeowners using Husqvarna pole saws and select compatible chainsaws. It provides the necessary structural rigidity and chain guidance required for precision pruning and limbing tasks, offering exceptional durability in demanding outdoor environments. While this bar is built to Husqvarna's high engineering standards, users must ensure the chain pitch and gauge match their specific saw model before installation to maintain optimal safety and performance.

No, this is a special bar designed specifically for pole saws and select compatible models. Please check your manual for the exact bar specification.
It is recommended to flip the bar every time you replace or sharpen the chain to ensure even wear.
Standard combination tools (scrench) provided with your Husqvarna saw are sufficient for installation.
No, you must use a chain that matches the specific pitch and gauge requirements of this bar model.
If you notice the rails have become thin or jagged, or if the chain no longer tracks straight in the groove, it is time for a replacement.
Check chain tension and inspect the bar rails for burrs or excessive wear that may have widened the groove.
Verify that the oil hole is not clogged and that the pole saw is successfully delivering oil to the chain.
This is usually caused by unevenly sharpened chain cutters or burrs on one side of the bar rail; file the rails flat or sharpen the chain.
To install the bar, loosen the side cover nuts on your pole saw and remove the old assembly. Ensure the mounting holes align perfectly with the bar tensioning pin before tightening the chain. Always check that the chain is correctly seated in the groove and that the tension is adjusted so the chain can be pulled around the bar by hand but stays snug against the rail.
For care, clean the bar groove regularly using a flat screwdriver or dedicated cleaning tool to remove packed sawdust and resin. Check the tip sprocket periodically for smooth rotation and ensure the lubrication hole is clear of obstructions to prevent overheating. Always use high-quality bar and chain oil to keep the rails lubricated during operation.
