All tools used for heavy-duty jobs require maintenance to keep them working at their optimal levels. Especially tools like chainsaws which need special attention because you cannot afford to keep using them for too long without proper service. Given the hazards associated with chainsaw operation, they need regular and proper service, repair, and chain replacement to prevent any issues.
Importance of Chain Maintenance
Lack of proper maintenance, timely repair and replacement can render the chain dull which will cause it to catch wood and kick back while the saw is in use. Not only will it decrease efficiency, but it can also cause serious injury to you and others around you. A poorly maintained chainsaw is both a hazard and an inefficient tool.
The chain is the most important component in a chainsaw. The chainsaw chain in good condition will allow you to make powerful and quick cuts, actions the chainsaw is meant to perform. Every time the chainsaw is used, the chain gets more worn than any other part. Excessive wear to the chain can badly affect both efficiency and safety. The chain should be regularly checked and replaced if you notice any signs of significant wear.
When to replace your chain?
There are certain clear signs that indicate it’s time for the chain to be replaced, these signs include:
- The chainsaw is beginning to rattle, jolt, and bounce.
- The cut starts becoming excessively crooked and jagged, as the cutting teeth have dulled.
- The chain shows missing drive links, which is a serious situation as it means the end of its service life.
Measuring a Chainsaw Chain
So, once you know its time to replace your chainsaw chain, how do you go about finding a new one? The following tips and steps should help you:
1. Measure the Pitch
The pitch refers to the gap between the drive links on the chain. Measure the distance between any 3 consecutive rivets and divide the number by 2. The typical chainsaw chain will have one of the following pitches:
- 0.325 inch
- 3/8 inch
- 0.404 inch
When you buy a chainsaw guide bar You should also check it has a suitable pitch. This is usually labelled on the product.
2. Measure the Gauge
The gauge refers to how wide the lugs are. Lugs are those sections of the chain that go into the guide bar. You will need a calliper to measure the gauge. The most common gauge measurements for chains are:
- 0.050 inch
- 0.058 inch
- 0.043 inch
- 0.063 inch
Again, the guide bar may be able to provide you with this information.
3. Measure The Number of Drive Links
Counting the number of links is also an important part of the process of how to measure a chainsaw chain. This must be done through manual counting. Make sure to count multiple times to confirm the number.
Conclusion
Most chainsaws will have a manual that provides information on the chains best suited for that specific model of saw. If you know the model of the saw, use this information to find the right replacement chain at a chainsaw parts supplier.
It is also important to consider the type of chain you will need. For example, full chisel chains can cut more powerfully and quickly. They are perfect for larger logs and wooden pieces. But these chains have dirt sensitivity and have higher risks of kickbacks, as they don’t have safety chain elements. You may want to choose semi-chisel chains. They may cut slower, but they retain their sharpness for longer. They are considered perfect for rougher sawing conditions and ideal for use with dirty wood, softwood, frozen wood, and dry wood.
