CHECKING OIL SUPPLY
• After starting the engine, run the chain

(1) Chain oil
The oil reservoir has a capacity sufficient
to provide about 40 minutes of cutting
time (when set to deliver the minimum
flow rate, or about as long as you'll get
from a tank of fuel). Be sure to refill the oil
tank every time when refueling the saw.
