OPERATION

Lubrication

Saw chain is automatically lubricated when the tool is
in operation. Check the amount of remaining oil in the
oil tank periodically through the oil inspection window.
To refill the tank, lay the chain saw on its side, then push
the oil tank cap, and then remove the oil tank cap. The
proper amount of oil is 200 ml (6.8 fl oz). After refilling the
tank, make sure that the oil tank cap is tightened securely.
