How to Measure a Pole Saw Chain?

Knowledge Based

Replacing a pole saw chain isn’t as simple as grabbing any size off the shelf. To get the right fit, you need to know a few key measurements that ensure safe and efficient performance. If the chain is too long, too short, or the wrong gauge, it can cause your saw to jam or wear out quickly. In this guide, you’ll learn how to measure a pole saw chain correctly, whether you’re checking a worn one or ordering a spare.

Measuring a Pole Saw Chain Length

When it’s time to replace your pole saw chain, knowing the correct size is essential. Using the wrong chain length or pitch can damage your saw or make it unsafe to operate. Pole saw chains are measured not just by their overall length but by three specific factors: pitch, gauge, and the number of drive links. Understanding how to measure these accurately will help you get the right replacement every time.

Things You’ll Need

Before you start measuring, gather a few basic items. You’ll need a tape measure or ruler, a flat workspace, and, ideally, your pole saw’s user manual. If the manual isn’t available, no problem, you can still get accurate measurements manually. Wearing gloves is also a good idea, since chains can be sharp or greasy.

Steps

Finding the Measurements on the Polesaw

Many pole saws have the chain specifications stamped or printed somewhere on the tool, often near the base of the bar or inside the sprocket cover. Look for three numbers: the pitch (like 3/8″ or 0.325″), the gauge (e.g., .050″ or .043″), and the number of drive links. These details are usually all you need to order the correct chain.

Measuring the Chain Manually

If you can’t find the specs on the tool, you can measure the chain directly. First, count the number of drive links, the small teeth on the underside of the chain that fit into the bar. Then, measure the pitch by calculating the distance between any three rivets on the chain and dividing by two. For the gauge, use a caliper or a precision ruler to measure the thickness of the drive links that fit into the bar groove. Matching all three ensures compatibility with your pole saw.

Tips

If you’re replacing a worn or stretched chain, it’s best to bring the old one along when buying a new one, especially if you’re unsure of the measurements. Double-checking measurements helps avoid costly mistakes. Always disconnect the pole saw from its power source before handling the chain. Lastly, if you’re uncertain, a local hardware store or service center can usually confirm the correct size for your model.

Final Takeaways

Measuring a pole saw chain isn’t complicated once you know what to look for. Focus on pitch, gauge, and drive link count, and don’t rely on overall length alone. Whether you find the specs on the saw or measure manually, taking accurate measurements ensures you get the right chain for safe and smooth cutting. A properly fitted chain makes your pole saw work better and last longer.
