CARE: The chain may cause injury. Be careful how you handle it. Wear gloves until you are used to the chain saw.
This skill will come with use, it might take some adjustment to get the perfect amount of slack in the chain.
Check the chain for smooth rotation and proper tension while moving it by hand. If necessary, readjust with the chain cover loose.
Once the chain is at the right tightness, tighten the two nuts using the appropriate tool.
Now read the safe operating instructions and the chapter on safe use of the chain saw.
Note: A new chain will expand its length in
the beginning of use. Check and readjust the tension frequently as a loose chain can easily derail or cause rapid wear of itself and the guide bar
