Checking Chain Lubrication
The saw chain must always throw off a small amount of oil.
Never operate your saw without chain lubrication. If the
chain runs dry, the whole cutting attachment will be irretrievably
damaged within a very short time. Always check chain lubrication
and the oil level in the tank before starting work.Every new chain has to be broken in for about 2 to 3
minutes.After breaking in the chain, check chain tension and adjust if necessary – see "Checking Chain
Tension".
