Allow the chain to cut for you. Exert
only light downward pressure. If you
force the cut, damage to the bar,
chain, or engine can result.
Releasethethrottle trigger as soonas
the cut is completed, allowing the en-
gine to idle. If you run the saw at full
throttle without a cutting load, unnec-
essary wear can occur to the chain,
bar, and engine.
To avoid losing control when cut is
complete, do not put pressure on saw
at end of cut.
