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. After refilling
the tank, make sure that the oil tank cap is tightened
securely.

After refilling, hold the chain saw away from the
tree. Start it and wait until lubrication on saw chain is
adequate.
