 Keep the engine at full throttle the entire time
you are cutting.
 Allow the chain to cut for you; exert only light
downward pressure. Forcing the cut could result
in damage to the bar, chain, or engine.
 Release the throttle trigger as soon as the cut is
completed allowing the engine to idle. Running
the saw at full throttle without a cutting load can
result in unnecessary wear to the chain, bar, and
engine.
 Do not put pressure on the saw at the end of
the cut.
