How To Put A Chain On A Chainsaw

When cutting timber for any duration of time, it’s likely that your chainsaw chain will become heated up and will stretch. When this occurs, the chain may just fall away from the bar. In fact, the same thing can happen if your saw becomes jammed in a tree trunk or log of wood. If this is the case, it’s possible that you’re allowing the chain to run loose, and might need to adjust it periodically.

Moreover, when the chain becomes overheated, expands or begins to fall away, you might also need to lubricate the chain by adding some bar oil to it.

Getting Started

All you need to put a chain on a chainsaw are few basic tools, like a ½” chainsaw wrench, a basic cleaning brush or even a paintbrush and leather gloves. If you have these tools, putting the chain back on is a fairly easy task. Ensure you have a clear space to work in. You would require an area where you can set down the materials while you work without worrying about misplacing them.

Step 1 – Cleaning The Chainsaw Bar and Chain

Always make it a point to wear protective leather gloves whenever you are working with your chainsaw. Before placing the chain back on, clean all the debris from the saw and the bar. Use the brush to clean remaining bits of wood or sawdust.

Step 2 – Removing The Nuts and Housing

  • A) Using the ½” chainsaw wrench, loosen both the bar nuts.
  • B) Use the slotted end of the chainsaw wrench to loosen up the tension screw just below the bar nuts; this will relieve the tension on the bar.
  • C) Now remove the bar nuts as well as the chainsaw’s plastic housing.

Step 3 – Replacing The Chain

  • A) Check the chain and ensure it is facing the correct direction. The teeth of the chain need to be facing away from your body while you’re holding the saw.
  • B) While fitting the chain around the sprocket, make sure it’s aligned along the bar’s grooves.
  • C) The tension stud needs to be in line with the guide hole.
  • D) Pull the chainsaw chain to tighten it and then adjust the tension screw till you have the required tension.
  • E) Place the plastic housing over the saw, ensuring that the holes for all the screws are aligned properly.
  • F) Insert all screws and then tighten them by hand.
  • G) Check the tension of the chain again properly before you tighten the screws using the wrench’s slotted end.
  • H) If required, adjust the tension screw just a little more. Pull on the chain to check that it’s spinning freely, as it should.

Step 4 – Test Your Chainsaw

  • A) Now start the saw and rev it up a few times.
  • B) Turn off the saw and then test the tension one more time to ensure it is tight. If it is, you can then get back to cutting.
  • C) If it loosens back up, you’ll need to readjust its tension and then re-tighten the nuts.

Once you have learnt how to put a chain on a chainsaw and practised a few times, the process will be much easier. It’s a good idea to learn exactly how it’s done, as this will help to ensure that your work progresses in an unhindered manner when you are out on the job.
