Sharpening Chain
Sharpening Essentials
It is essential that the chainsaw chain is kept sharp. A correctly sharpened chain will cut much more
effectively with minimal force required.
Never use a dull or damaged chainsaw chain as this may lead to increased physical injuries, increased
vibration levels, unsatisfactory cutting results and increased wear to the unit.
Try to sharpen often rather then alot at once. The aim of sharpening the chain is to hone the edge
rather then remove excessive amounts of material to create a new cutting edge.
Before sharpening the chain make sure it is well secured and there is no chance of the unit starting -
remove the shark plug before performing any maintanence on the chainsaw.
It is important that the correct file size and file guide is used to sharpen the chain, failure to do so
may result in increased physical injuries, increased vibration levels, unsatisfactory cutting results and
increased wear to the unit.
