Checking Chain Lubrication

The saw chain must always throw off a
small amount of oil.
NOTICE
Never operate 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".
