MAINTAINING THE SAW CHAIN
For safe, ecient operation, the saw chain must be maintained properly.
The saw chain will wear with use, causing the chain to stretch. This is normal. When it is no longer
possible to obtain a correct chain-tension adjustment, the saw chain will need to be repaired by an
authorized service center or replaced. Refer to Replacing the Guide Bar and Saw Chain.
Always keep the saw chain sharp. During operation, look for the following indicators of a dull saw chain:
• Wood chips are small and powdery.
• The saw chain must be forced through the wood.
• The saw chain cuts to one side.
WARNING: The saw chain is very sharp. Always wear heavy-duty protective gloves
when handling or performing maintenance on the saw chain.
WARNING: An improperly sharpened saw chain increases the chance of kickback.
Failure to replace or properly maintain the saw chain can cause serious injury.
