Checking Chain Lubrication Chain Brake
143BA024 KN
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 oil level in tank before starting work.
Every new chain has to be broken in for about 2 to 3 minutes.
After breaking in chain, check chain tension and adjust if necessary – see “Checking Chain Tension”.

Releasing the chain brake
:Pull the hand guard back toward the front handle.
Always disengage chain brake before accelerating engine and before starting cutting work. The only exception to this rule is when you check operation of the chain brake.
High revs with the chain brake engaged (chain locked) will quickly damage the powerhead and chain drive (clutch, chain brake).
