A chainsaw is a very handy tool for those who like to work with wood. It is also ideal for larger pruning requirements and for cutting firewood in winter. The chain on a chainsaw can get loose when it gets hot from continued use over a long period and the chain stretches. It can also come loose when the saw gets jammed on wood while pruning or cutting. Jammed pieces of wood chips, even sawdust can also cause the chain to come loose. When this happens, you should be able to put the chain back on with ease with these tips outlined below.
- Chainsaws are built differently according to manufacturer and brand but will always be taken apart almost the same way. Place the chainsaw on its side on a table, the teeth of the saw should be facing the other direction and away from you.
- With the chainsaw wrench release the bar tension and remove the cover by loosening the cover bolts and the tension screw. Remove the drive cover.
- Just like putting back the chain on a bicycle, place the chain over the clutch and align it around the back sprocket near to the chain tension nipple along the bar’s grooves, and around the front sprocket ensuring that the chain tension nipple is lined up and fits into the hole at the end of the bar.
- Ensure that the cutters on chain are facing forward as it is very easy to place the chain backwards. Pull the chain a bit to ensure that it is properly aligned on the sprockets and grooves and running through.
- Put the drive cover back on tighten the stud screws with your hand. You do not have to tighten it too much as you still need to check the tension of the chain at this stage. The chain will still be slack. Pull the chain forward to ensure that it is still aligned with the sprockets and moves smoothly.
- When you are assured that the chain is aligned, get your screwdriver and insert it in the slot on the drive cover. Turn the tool clockwise. You will see the bar moving out and the chain tightening up as you keep turning your universal tool.
- When you have achieved the desired tension, you can now complete the tightening of the cover studs.
- Again, you have to check the tension and alignment of the chain by sliding the chain forward. Make sure that it is at the recommended tension and that that chain is engaged in all the sprockets and grooves.
- Test your chainsaw and make adjustments as needed. You should be able to lift the chain off the sprocket for about a quarter of an inch. This slack will ensure that you have the right tension for the chain and will make sure that the chainsaw will run without a hitch.
When you have taken the chainsaw apart to put back the chain, use this as the opportunity to clean your chainsaw and add lubrication to all moving parts. You should also sharpen the cutting blades as this will allow for easy cutting and will protect the bar from wear and tear. Proper maintenance will extend the life of your chainsaw. Wear tight clothing to ensure that the chainsaw will not snag on your clothes and the required safety gear to protect parts of your body when using a chainsaw.
