Stop the engine . bl Turn saw on its side with oil cap up Figure e In freezing weather oil will thicken , making it t2 necessary to thin bar and chain oil with a CoLoosen cap slowly and wait for pressure in small amount of Diesel Fuel # 1 or Kerosene . the tank to be released before removing the Bar and chain oil must be free flowing for the cap . oil system to pump enough oiI for adequate d . Fill the oil tank ° Replace the oil cap securely , 3 , IMPORTANT POINTS TO REMEMBER Fill the oil tank each time you refill the fuel tank to ensure there wil ! be sufficient oil for the chain whenever you start and run the saw , , The saw will use about t / 2 tank of chain oil for each tank of fuel mixture . If less oil is used , check for a plugged oil hole in the guide bar , It is normal for a small amount of oil to ap - pear under the saw after the engine stops . This is due to oil draining from the bar and chain when not in use Figure 12
