Well, we are going to make you happy once again.

How Does a Chain Get Off from the Bar?

There are several reasons for your chainsaw chain to get off from the bar. Among them the most common reasons are:

  • Due to overheating caused by the continuous operation of the chainsaw. When your saw chain gets overheated, the length of the chain also increases. Eventually, it pops out from the bar of your chainsaw. 
  • If your saw chain has been running for a long time and you didn’t bother to tighten up the chain tension. This causes the chain to loosen up and may fall back while you operate. 
  • When a piece of the log you are cutting jams your chainsaw chain, the chain may pop out from its bar.
  • Chainsaw chain is placed on the saw bar and fastens with screws. If the screws become unusable and cannot hold the chain on the bar, the chain might fall.

Anyway, whatever the reason, we will fix it and get back our saw chain to its respective place. To make the process easier and more professional, we have decided the whole process into five easy and convenient steps. Read carefully and follow the steps to put back the chain on a chainsaw like a pro!! 

Preparation of Fixing the Fallen Chain

  • Wear the protective hand gloves and full sleeve shirt for safety measures.
  • Find a clear and spacious place to fix your fallen chain. Because, during your fixation, you will have to disassemble a few parts of the chainsaw and those parts need to be stored carefully. You will have to suffer if you lose any vital parts during the fixation.
  • Get a piece of cardboard or newspaper so that you can put your tools and disassembled parts. This might ensure no loss of important parts.
  • Make sure that the chainsaw is in Off position and safety case is locked.
  • Place the saw in front of you by positioning the engine towards you and the tip of the blade away from you.
  • Get a ½ inch Wrench, a drift, and a hammer(medium-sized).
  • Oil and Brush for cleaning and greasing.

Steps of Putting Back a Chain on Chainsaw

Just follow these simple four steps one by one to do the process like a Pro!

Step 1- Remove the Bar Screws and Housing

With the help of your wrench, unscrew the bar nuts of both upper and lower end of your saw chain. To loosen the tension screw to relieve the bar tension, use the slotted end of your wrench. When you’re finished, remove the bar nuts as well as the plastic housing of the saw.

Step 2 – Clean the Bar and Chain

Once you loosen up the chain and plastic hatch cover, make sure that you clean up the parts of the chainsaw as much portion as you can. First of all, use a paintbrush to remove dust and dirt, and then use oil to clean the parts. Furthermore, do not forget to grease the chain before you put it back on your chainsaw. 

Step 3 – Re-assign the Chain to its Bay 

  • Align the chain with the grooves of the bar while securing the chain around the sprocket. Now, ensure that the tension stud is in-lined with the guide hole.
  • Pull the chain until you get your desired tension. Remember, over or under tension is equally problematic; try to make it as optimum as possible.
  • Now, get the plastic housing back to its place and do hand-tighten up all the screws and nuts.
  • Before you do final tightening and securing your saw chain, watch for the tension of the chain one more time. If required tighten or loosen up the chain tension screw accordingly.
  • Now, use your wrench to tighten up the nuts and screws firmly so that they do not make any operational hazard during your cutting jobs.

Step 4- Give Functional Test of the Chainsaw

  • Take safety precautions from any unwanted popping out or tearing out of the saw chain. Now, start the chainsaw and run it for a few minutes. 
  • After a few minutes, turn off the chainsaw and back it On again for one more time.
  • Now, shut off your chainsaw and observe the chain tension. If it is on the same you set a few minutes ago, then you are good to start your cutting job. 

N.B. If the chain tension loosens up, readjust it and do the functional test again. It is recommended that the chain can be lifted up-to ¼ inch so that it rotates smoothly during your cutting jobs.
