When to Change a Chainsaw Chain and Guide Bar | STIHL Chainsaw Maintenance | STIHL GB

In this video, we’ll cover the key points to consider when deciding if your chainsaw chain, chainsaw bar and sprocket need replacing. Whilst many people will just consider replacing the chainsaw chain, it’s important to consider the whole system as they all experience wear. Every tooth on a STIHL chainsaw chain will feature several wear markers. Sharpening the tooth and filing the depth gauge wears away at the steel and chrome plating, gradually reducing the size of the tooth, so once the wear markers have been reached it’s essential to replace the chainsaw chain. Ideally, you should reach the tooth and depth gauge markers at roughly the same time. If this isn’t the case, you may have sharpened the chain incorrectly, which can change the depth gauge settings and lead to either increased vibration or reduced cutting performance. The STIHL 2-in-1 EasyFile automatically maintains the perfect depth gauge setting, helping to make sure your chain lasts as long as possible. 🔶 STIHL 2-in-1 EasyFile: https://www.stihl.co.uk/en/ap/easyfil... A wear marker is also present along the underside of the tooth, above the ‘toe’ and ‘heel’. If the chain is run without bar oil, or is tensioned too tightly over long periods, the extra friction will lead to premature wear to the bottom part of the tooth. You should immediately replace the chain if you notice this wear marker has been reached. 🔶 Damaged or Missing Teeth It’s important that all the teeth on a chainsaw chain are uniform length to prevent increased vibration and the chain ‘snatching’ mid-cut. If the damage has significantly shortened or broken a number of teeth, it may not be practical to sharpen all the teeth to a uniform length, so a new chainsaw chain is needed. 🔶 When to Replace the Chain Sprocket Hidden behind the sprocket cover, the chain sprocket is the driving force behind the chain. The sprocket is subject to normal wear, so we recommend checking its condition at regular intervals using a control gauge. This can be used on both rim and spur sprockets featured on any petrol or cordless chainsaw or pole pruner so it’s definitely worth having one. 🔶 STIHL Control Gauge: https://www.stihl.co.uk/en/ap/control... The chain sprocket must be replaced if the depth of the wear marks reaches about 0.5mm. A seriously worn chain sprocket can cause the chainsaw chain and guide bar to wear at an increased rate, as well as reducing cutting performance too, so it’s important to keep an eye on it. 🔶 When to Replace Your Chainsaw Guide Bar Rail wear Over time, the rails of the guide bar can wear away, reducing the groove depth. If the groove depth is too small, the tips of the drive links will scrape along the bottom and drastically impact how smoothly the chain moves around the guide bar. Turning the guide bar over can also help to wear both sides evenly and extend the working life of the bar. Typically guide bars can last the lifespan of 4 chains, but if you have noticed some wear to the rails, check the groove depth using the tip of the depth gauge tool found in our filing kits. If the groove depth is less than the minimum listed in the description below, it’s time to change your bar. 🔶 STIHL Filing Kits: https://www.stihl.co.uk/STIHL-Product... b For further advice and support on chainsaw maintenance, visit your nearest STIHL Approved Dealer. 🔶 https://www.stihl.co.uk/en/dealers 🔶 STIHL Website: https://www.stihl.co.uk/ 🔶 Like us on Facebook:   / stihlgb   🔶 Follow us on Instagram:   / stihlgb   #STIHL #STIHLGB #STIHLChainsawChain #STIHLChainsawBar #STIHLGuideBar #ChainsawGuideBar #ChainsawMaintenance #STIHLMaintenance #ChainsawFiling #WhenToReplaceYourChainsawChain #WhenToReplaceYourChainsawBar
