As an avid chainsaw user, keeping my chain saw in peak operating condition is essential for efficiency, safety, and extending the life of my equipment. After years of trial and error learning how to properly maintain my chainsaw chain, I’ve discovered some best practices that have made a world of difference. In this guide, I’ll share everything I’ve learned about optimal chainsaw chain maintenance.
Proper care and maintenance of your chainsaw chain is crucial for several reasons. First, it ensures your chain saw continues to cut smoothly and efficiently through wood. A poorly maintained chain quickly becomes dull and bogged down in the cut. Second, proper maintenance greatly reduces the risk of dangerous chainsaw kickback which can cause serious injury. And third, keeping your chain well-oiled, tensioned and with sharp cutters will dramatically extend its usable life, saving you money on premature replacements.
By following some basic maintenance best practices, you can avoid many common chain saw problems and keep your chainsaw running safely and optimally for years of use. I’ll cover specific tips on lubrication, tensioning, sharpening, depth gauges, daily/weekly/monthly maintenance checks, when to replace a worn chain, critical safety precautions and more. Let’s get started!
What are the best practices for chainsaw chain maintenance?
Keeping your chainsaw chain properly oiled is one of the most important maintenance tasks for optimal cutting performance and longevity. The chain oil lubricates the chain, guide bar, and drive sprocket to prevent overheating and excessive wear from friction.
Without adequate lubrication, the chain will quickly stretch, deform and deteriorate. The constant friction under heavy loads and high RPMs can also warp or damage the guide bar. Many premature chain and guide bar replacements are due to insufficient oiling.
Most chainsaws have an automatic oiler that feeds oil to the chain while running. Regularly check your saw’s chain oil tank level before use and refill as needed with bar and chain oil. Make a habit of inspecting the underside of the guide bar for adequate oil drips when making a cut. Adjust the oiler if needed to maintain good flow.
Correct Chain Tension
Maintaining proper chain tension prevents derailing, reduces vibration, and allows efficient cutting with lower chain drag. Check tension before each use by pulling the chain midway along the guide bar. It should have no more than 1/4-inch of vertical movement with light tugging.
Chains stretch over time and will need periodic re-tensioning. Use the saw manufacturer’s method to adjust chain tension – usually loosening guide bar nuts and adjusting tension screw. Be careful not to over-tighten, which can damage the bar and chain. The chain should spin freely by hand.
A loose chainsaw chain is dangerous and causes increased wear. It’s more prone to derailing which can damage the saw. The loose chain also absorbs energy during cutting instead of efficiently slicing the wood.
Sharp and Correctly Angled Cutters
Keeping the cutters consistently sharp is essential for clean, efficient cuts with less binding and kickback risk. Inspect cutters before each use and sharpen periodically as needed. Use a round chainsaw file and file guide to maintain the correct sharpening angle according to manufacturer’s specs for your saw chain.
A few strokes on each tooth is often all that is needed to restore sharpness. Make sure depth gauges are also filed down uniformly to achieve proper clearance above the freshly sharpened cutters. This allows smooth cutting without the depth gauges hindering the cutters from engaging the wood.
As chains wear out over time, the cutter teeth get shorter and the depth gauges relatively higher. This reduces cutting performance. Replacement is needed when sharpening no longer restores good cutting ability due to excessively worn cutter length and non-adjustable depth gauges.
Consistent and Correct Depth Gauge Height
Closely related to cutter sharpening is maintaining proper depth gauge height. The depth gauges ride ahead of each cutter and determine how deep it cuts into the wood. If gauges are too high from uneven filing, the chain will bind and cut poorly.
Use a depth gauge tool to quickly file down gauges uniformly when sharpening the cutters. Consistent depth gauge height is critical for smooth cutting without compromising kickback protection. Some chains have engineered safety features that prevent over-filing depth gauges excessively. Refer to your chain’s specifications for allowable gauge filing ranges.
Chainsaw Maintenance Tips
Proper chainsaw maintenance requires regular attention to ensure optimal performance and safety over the life of your saw. Here are some helpful maintenance tips:
- Clean the exterior of the chainsaw to remove any wood chips, oil drips and other debris after each use. This prevents buildup of flammable contaminants.
- Check the chain/bar oil tank level and refill as needed. Running with low oil will quickly ruin bars and chains.
- Examine the chain’s cutter sharpness. Touch up with a file if needed to maintain a razor edge.
- Inspect cooling intake and flywheel exhaust ports for any sawdust or debris obstruction which can lead to overheating. Clean as needed.
- Check for any loose nuts/bolts and damage to anti-vibration mounts which impair handling and control.
- Examine the chain brake band for wear and ensure it engages/releases properly. Replace worn brake bands immediately.
- Inspect the clutch drum, shoes and springs for deterioration which can cause clutch slippage.
Chainsaw Chain Replacement
Eventually chains will reach the end of their usable lifespan and need replacement. Learning when and how to swap chains will save headaches and extend your saw’s productivity.
Signs of a Worn-Out Chain
It’s time to replace a chain when:
- Sharpening no longer restores adequate cutting performance due to excessively worn cutter teeth.
- The chain cuts slowly with increased effort, even when sharpened.
- Cutters develop cracks or pieces break off from wear and impact forces.
- Depth gauges are not adjustable down to the proper height above cutters due to being worn down too far.
- Links are badly stretched, stiff or deformed from prolonged use and past damage.
How to Replace a Chainsaw Chain
- Remove the old chain – Loosen guide bar nuts and tensioner to derail chain. Clean guide bar groove to remove debris.
- Inspect guide bar – Check for wear and damage. Filed down rails indicate replacement time. Replace if sprocket nose is excessively worn.
- Select new chain – Match to bar length and drive sprocket pitch/gauge. Chains are non-interchangeable.
- Install new chain – Derail from bar, wrap around sprocket nose then loop around guide bar. Engage drive links into sprocket.
- Adjust tension – Tighten bar nuts to finger tight. Tension chain according to manufacturer’s method until spin free with .25″ vertical movement mid-bar.
- Confirm oil flow – Start saw and check oil slinging off chain before making cuts.
Chainsaw Safety Tips
While essential maintenance extends the productive life of chainsaw chains, proper handling and safety practices are critical to avoid injury. Here are some key safety tips:
Personal Protective Equipment
Chainsaw operators must wear appropriate PPE:
- Safety goggles/face shield – Protects eyes from sawdust and flying debris.
- Hearing protection – Chainsaws typically operate above 85 decibels.
- Heavy work gloves – Improves grip and protects hands from sharp chain.
- Chainsaw chaps – Stops the chain instantly against legs if kickback occurs.
- Steel-toe boots – Protect feet from falling trees/logs.
- Hard hat – Protects head from overhead falling objects.
Proper Chainsaw Handling
- Maintain steady footing and balance. Don’t cut while on ladders or in trees.
- Firmly grip rear handle with right hand (or left for lefties) and wrap left thumb over front handle.
- Keep bystanders and animals well away from cutting area.
- Don’t cut with chainsaw tip. Initiate cuts with lower quadrant of bar tip.
- Shut off saw or engage chain break when carrying/transporting over longer distances.
- Shut off saw before setting it down.
- Follow all manufacturer safety guidelines. Get professional training if unfamiliar with proper cutting techniques.
Regular chainsaw chain maintenance and sharp cutters are essential for optimal cutting performance, safety and extending the life of your equipment. Just a few minutes per day keeps your chain in top shape. Proper lubrication, tension, cutter sharpening, depth gauge filing and debris cleaning prevents many common problems and costly repairs. But always respect the powerful cutting forces and kickback potential of chainsaws by wearing proper PPE and using safe operating techniques. Follow my tips and enjoy years of smooth-cutting with your well-maintained chainsaw.
Frequently Asked Questions
How often should I sharpen my chainsaw chain?
It’s a good idea to check chain sharpness before each use and sharpen as needed. Typically every 10-20 cuts may require some quick touch-up filing depending on cut length and wood type. If making many small cuts, daily sharpening may be needed.
What type of oil should I use for my chainsaw chain?
Use a quality bar and chain oil designed for chainsaw lubrication. It has sticky tackiness to stick to the chain and bar under centrifugal force and high heat. Never use used or reclaimed oil which lacks proper lubricating properties.
How do I know when it’s time to replace my chainsaw chain?
Replace chains when cutters are extremely worn and sharpening no longer restores good cutting. Also replace if links are stretched, stiff or damaged. If the chain cuts slowly or binds in the cut, it likely needs replacing regardless of apparent wear.
Can I use my chainsaw in wet conditions?
It’s best to avoid wet cutting which accelerates wear and corrosion. But if necessary, reduce risk of electric shock on electric saws by using a GFCI and waterproof boots. Check that the engine air intake on gas saws remains clear of water ingestion. Dry the saw and chain immediately after to limit water damage.
How do I store my chainsaw when not in use?
Fully clean the saw and chain of all debris, sap and dirt. Lightly lubricate the chain to prevent rust. Drain or treat fuel in gas saws. Store chainsaw in clean, dry protected area away from children, high heat and humidity.
What are some common chainsaw chain problems and solutions?
Chain jumping – re-tension chain. Binding/pinching – sharpen cutters and file depth gauges. Reduced cutting speed – sharpen or replace chain. Excessive stretch – replace worn chain. Overheating – check chain oil flow and clean oil passageways.
How can I prevent kickback while using my chainsaw?
Maintain properly sharpened cutters, steady hand support and initiate cuts with lower bar quadrant only. Don’t cut with the saw tip or let the top quadrant contact wood during cuts. Also install low-kickback safety chains on saws used for limbing or inexperienced users.
