If you are the owner of a chainsaw then you will want need to be aware of how to replace the chain as this is a part of normal usage of the tool. The chainsaw chain will wear out and need replacing, and this is just part of the process of having one, and using it. The replacement of the chain can be a little different for each style but basically they are all very similar. Trusted brands like STIHL chain saws will have instructions on how to get into the machine to do the job. Here are the basic steps to replacing the chain.
Get a Replacement Chain that Matches the One You are Removing
The first step to replacing the chain would have to be ensuring that you have the right chain for the chainsaw that you are using. Often this information will come with the chain saw, or you could always take the chain saw in to the hardware store when you buy the new one.
Removed Old Chain
Firstly remove the guide bar side panel which is usually held on by two nuts. Unscrew the nuts and remove the guide bar, which will reveal the ‘guts’ of the machine and give you access to the chain. (Sometimes the brake is attached to the chainsaw, so if this is the case, make sure you unscrew the brake from the guide bar before you remove it.)
Release the Chain Tension, Remove Chain and Loosen Tension Screw
Once the sprocket plate is off the chain is ready to be removed. Pull the nose of the chainsaw bar away from the chainsaw to release it from the tensioner. Once you have done this, the chain should come away easily from the guide bar because of the slack that it will now have. Next pull the drive links out of the guide bar and carefully manoeuvre the other end of the chain around the clutch drum. Loosening the screw on the inside side of the guide bar will make fitting the new chain easier.
Thread New Chain Onto Saw
With great care, thread the new (or sharpened) chainsaw chain around the end of chain saws clutch drum, ensuring that drive links engage in the sprocket. Then thread the rest of the drive links into the guide bar and around the nose of the saw.
Align and Replace the Guide Bar
Once the chain has been properly threaded and is in place, pull out the nose to apply tension to the chain. While pulling the guide bar, ensure that you align it with the adjustment pin. Once the guide bar is properly positioned, replace the guide plate and put in the nuts that hold it in position, but do not tighten them all the way yet. The guide bar needs to move a little while you adjust the chain to the correct tension.
Tighten Tensioning Screw and Guide Bar Nuts
Adjust the tension of the chain by tightening the tension screw next to the guide bar. Finish tightening the nuts on the guide bar, as tight as they go. Now your chainsaw is ready for use.
