WARNING
To reduce the risk of personal injury from loss of control
and/or contact with the saw chain, do not use your saw with
incorrect idle adjustment. At correct idle speed, the chain
should not move. If the chain continues moving when the
engine is idling, have your saw checked and repaired by
your servicing dealer.

speed screw (LA) half a turn clockwise and restart the

begins to run.
