Husqvarna Light Bar 3/8 x .063

The Husqvarna light bar in 3/8 pitch and .063 gauge cuts weight off the front of a big saw without giving up length. It is a good fit for pro saws used on long days of felling and bucking, where every bit of nose weight shows up in your arms.

Why run a light bar

A long bar on a 70 cc or bigger saw puts a lot of weight out front. A light bar trims that, so the saw balances closer to your hands. On a day of bucking or felling, that means less fatigue and better control at the end of the cut.

Light bars still need to be matched correctly. Order the length your saw can pull well, and pair it with a 3/8 pitch, .063 gauge chain with the right drive link count. More bars are in chainsaw bars.

On a typical removal, the big saw comes out for the trunk and the spar wood, and that is where a long bar earns its keep. Shaving weight off the nose makes it easier to keep the bar level through a long back cut and to hold the saw steady while bucking.

Care and wear

Keep the oil holes and groove clean, check the sprocket nose for play, and file off rail burrs. Flip the bar at chain changes so both rails wear evenly.

Light bars can be less forgiving of pinches and pry loads than solid bars, so avoid levering with the bar. Replace it if the rails are uneven, the groove is shallow, or the bar is bent.

Check the sprocket nose for play at every chain change and grease it if your bar calls for it. Run the oiler at a setting that keeps the chain wet in long cuts. A dry bar on a big saw overheats quickly and wears rails out fast.
