It is possible to sharpen the chain on your LP1000 yourself, as long as you remove the chain bar and chain from the unit, using a vice.
Hold the chain bar in a vice and place the chain on it as a means to help hold the chain. You need to hold the chain on the bar the whole time you sharpen the chain.
A 4 mm chain file is the required file, available at a home center or hardware store.
Please refer to the attachment for further information.
IT IS UNSAFE TO SHARPEN THE CHAIN WHILE INSTALLED ON THE SAW.
