How To Put A Chainsaw Chain On: Step-by-Step Guide
Can I put a chainsaw chain on myself? Yes, you absolutely can put a chainsaw chain on yourself with the right guidance and tools. This guide will walk you through every step of your chainsaw chain replacement, ensuring you can do it safely and efficiently. We’ll cover everything from preparing your chainsaw to making the final tension adjustments.
Getting Ready for Your Chainsaw Chain Replacement
Before you even think about fitting a new chainsaw chain, there are a few crucial preparation steps. Taking these moments upfront will save you frustration and potential mistakes later. This is a key part of good chainsaw maintenance.
Gathering Your Chainsaw Parts and Tools
You’ll need a few essential items before starting. Having everything ready means you won’t have to stop midway through.
- New Chainsaw Chain: Make sure it’s the correct size and type for your chainsaw bar and chain. Check your chainsaw’s manual or the existing chain for specifications like pitch, gauge, and drive link count.
- Chainsaw Bar: Inspect your current bar for any damage, wear, or warping. If it’s damaged, it’s time for a new chainsaw bar and chain.
- Scrench (Chainsaw Tool): This is a combination tool often supplied with chainsaws. It has a screwdriver and a socket wrench.
- Gloves: Heavy-duty work gloves are a must for protecting your hands from sharp chain teeth and grease.
- Safety Glasses: Always wear eye protection.
- Owner’s Manual: Your chainsaw’s manual is your best friend for specific instructions.
Safety First: Essential Precautions
Chainsaws are powerful tools. Safety must be your top priority.
- Disconnect Spark Plug: This is the MOST important safety step. Before touching any part of the chainsaw, disconnect the spark plug wire. This prevents accidental starting.
- Cool Down: Let the chainsaw cool down completely before you begin. The engine and chain can be very hot.
- Stable Surface: Work on a flat, stable surface. This prevents the chainsaw from rolling or moving unexpectedly.
Step-by-Step: Installing the Chainsaw Chain
Now that you’re prepared and understand the safety measures, let’s get to the actual installation of the chainsaw chain. This process is straightforward once you know the mechanics.
Step 1: Removing the Old Chainsaw Chain (If Applicable)
If you’re replacing an old chain, you need to remove it first.
- Loosen Tensioning Screws: Locate the tensioning screws on your chainsaw. These are usually on the side or front of the chainsaw. Use your scrench to loosen them. This will relieve tension on the chain.
- Remove Clutch Cover/Side Panel: Most chainsaws have a side cover that houses the clutch and chain brake. Remove the nuts holding this cover in place using the appropriate socket on your scrench.
- Slide Off Old Chain: Once the cover is off, carefully slide the old chain off the chainsaw bar. Be mindful of the sharp teeth.
Step 2: Positioning the New Chainsaw Chain
This is where you start installing the new chainsaw chain. Pay close attention to the direction of the cutters.
- Identify Cutter Direction: Look closely at the teeth of your new chainsaw chain. They are angled to cut in a specific direction. The cutting edge of each tooth should face forward, away from the handle, on the top side of the chainsaw bar.
- Place Chain on Bar: Drape the new chainsaw chain around the chainsaw bar. Make sure the drive links of the chain fit into the groove of the bar.
- Engage Drive Sprocket: With the chain loosely around the bar, ensure the drive links are properly seated around the drive sprocket inside the clutch housing. This is a critical step.
Step 3: Reattaching the Clutch Cover
Now, it’s time to put the cover back on.
- Align Cover and Studs: Carefully place the clutch cover back onto the chainsaw. Align the holes in the cover with the studs on the chainsaw body.
- Install Nuts: Thread the nuts back onto the studs. Tighten them finger-tight for now. You’ll tighten them fully after tensioning the chain.
Step 4: Adjusting Chainsaw Tension
This is perhaps the most critical part of the installation. Proper tension is vital for performance and safety. This is also known as how to tension a chainsaw.
- Apply Initial Tension: Locate the chain tensioning screw again. Slowly turn the screw to apply tension to the chain. You want to snug it up so the chain doesn’t sag excessively.
- Check for Sag: Gently pull the chain around the bar. It should move smoothly. There should be a slight sag on the bottom of the bar, just enough so you can feel the chain but not so much that it falls off.
- The “Slight Drag” Test: A common way to check tension is to pull the chain by hand. It should move freely around the bar with a slight drag. If it’s too tight, it will bind and be hard to move. If it’s too loose, it can jump off the bar.
- Securing the Bar and Chain: Once you have the right tension, hold the chainsaw bar up with one hand and tighten the clutch cover nuts securely with your scrench. This locks the bar and chain in place.
Step 5: Final Tension Check and Tightening
After securing the cover, it’s good practice to do one final check.
- Re-check Tension: Move the chain around the bar again. It should still move freely with that slight drag.
- Tighten Nuts Firmly: Ensure the clutch cover nuts are fully tightened. Do not overtighten, as this can damage the housing.
Fine-Tuning Your Chainsaw Cutting Edge
After you’ve installed the chain, there are a few more checks to ensure optimal performance. This is part of ongoing chainsaw maintenance.
Testing the Chainsaw Chain’s Movement
With the spark plug still disconnected, manually rotate the chainsaw chain several full revolutions.
- Smoothness: Does it move smoothly without any tight spots or binding?
- Obstructions: Is anything interfering with its rotation?
Reconnecting the Spark Plug
Once you’re confident the chain is installed correctly and moves freely, reconnect the spark plug wire.
After Installation: First Cuts and Adjustments
The moment of truth! Time to see how your new chainsaw chain performs.
Initial Cuts and Re-Tensioning
New chains, especially those made of steel, can stretch slightly during their first few uses.
- Make a Few Cuts: Start with a few short, controlled cuts.
- Check Tension Again: After these initial cuts, stop the chainsaw, let it cool, and disconnect the spark plug. Check the chain tension again. It might need slight tightening.
- Repeat if Necessary: You may need to re-tension the chain a couple of times in the first hour of use. This is normal for a new chainsaw chain.
When to Consider Chainsaw Chain Sharpening
Even with a new chain, proper technique and awareness of its condition are important. Your chainsaw cutting edge will dull over time.
- Signs of Dullness:
- Saw dust instead of chips: If your chainsaw is producing fine dust rather than distinct wood chips, the chain is likely dull.
- Saw pushing or binding: If you have to force the saw through the wood, or it tends to push away from your intended cut, the chain needs sharpening.
- Rough or jagged cuts: Clean, smooth cuts are a sign of a sharp chain.
- Sharpening Frequency: The need for chainsaw chain sharpening depends heavily on how much you use the saw and the types of wood you cut. Regular maintenance, including sharpening, is key.
- Sharpening Tools: You’ll need a round file of the correct size and a file guide. Your owner’s manual will specify the correct file size for your chain.
Troubleshooting Common Chainsaw Chain Installation Issues
Sometimes, things don’t go perfectly. Here are some common problems and how to fix them.
Chain Too Loose
- Problem: The chain falls off the bar or is very slack.
- Solution: Re-tension the chain. Ensure you tighten the clutch cover nuts after adjusting the tension.
Chain Too Tight
- Problem: The chain is difficult to move by hand, binds up, or causes the saw to overheat quickly.
- Solution: Loosen the clutch cover nuts, release some tension on the chain by turning the tensioning screw the opposite way, and then re-tension until it moves smoothly with a slight drag.
Chain Not Engaging Sprocket
- Problem: The chain doesn’t seem to catch on the drive sprocket.
- Solution: Double-check that the drive links are properly seated in the bar groove and that they are correctly positioned around the drive sprocket. You may need to remove the clutch cover again to ensure this.
Chain Not Moving Smoothly
- Problem: There are tight spots when you rotate the chain.
- Solution: This can happen if a drive link is bent or if dirt is in the chain. Inspect the chain for damage. Ensure the bar groove is clean.
Maintaining Your Chainsaw for Longevity
Proper chainsaw maintenance goes beyond just changing the chain. A well-maintained saw is safer and performs better.
Regular Cleaning
- After Each Use: Brush off sawdust and debris from the bar, chain, and engine.
- Clutch Cover Area: Clean out any accumulated sawdust from around the clutch and drive sprocket. This prevents overheating and wear.
Bar Groove Maintenance
- Keep it Clean: Use a brush or compressed air to keep the bar groove free of debris.
- Lubrication: Ensure the automatic chain oiler is working correctly. The bar and chain need constant lubrication to prevent friction and wear. Check the oil reservoir regularly.
Sharpening Strategy
- As Needed: Sharpen your chain when you notice a loss in cutting performance, not just when it’s completely dull.
- File Depth Gauge: As part of chainsaw chain sharpening, it’s also important to periodically file down the depth gauges if they become too high. This helps the cutters engage the wood properly.
Frequently Asked Questions (FAQ)
Q1: How often should I replace my chainsaw chain?
A: This depends on usage, but typically, a chainsaw chain should be replaced when it becomes significantly dull and can no longer be sharpened effectively, or if there is visible damage to the cutters or links. Some users replace their chain every time they sharpen it a few times, while others push it further.
Q2: What happens if my chainsaw chain is too loose?
A: A loose chainsaw chain can “jump off” the bar, which is extremely dangerous. It can also cause uneven wear on the bar, chain, and sprocket, and reduce cutting efficiency.
Q3: What happens if my chainsaw chain is too tight?
A: A chain that is too tight will create excessive friction. This can lead to premature wear on the chain, bar, sprocket, and clutch. It can also cause the saw to overheat and reduce its power output.
Q4: Can I use a chain from a different brand on my chainsaw?
A: You can, but only if it has the exact same specifications: pitch, gauge, and drive link count. Using an incorrect chain can damage your chainsaw. Always check your owner’s manual.
Q5: How do I know if my chainsaw bar is worn out?
A: Look for signs of wear such as a groove that is wider than normal, burrs on the edges of the bar, or if the bar is bent or warped. If the chain doesn’t run smoothly on the bar, it might be time for a replacement chainsaw bar and chain.
By following these steps, you’ll be able to confidently perform your chainsaw chain replacement. Proper chainsaw maintenance, including regular checks and timely adjustments to the chainsaw tension, will ensure your saw remains a reliable and safe tool for all your cutting needs.
