Saw Chain and Guide Bar Oiling (Fig. G)
Auto Oiling System
This chain saw is equipped with an auto oiling system that 
keeps the saw chain and guide bar constantly lubricated. 
The oil level indicator

 shows the level of the oil in the 
chain saw. If the oil level is less than a quarter full, remove 
the battery from the chain saw and refill with the correct 
type of oil. Always empty oil tank when finishedcutting.
NOTE: Use a high quality bar and chain oil for proper saw 
chain and bar lubrication. As a temporary substitute, a non-
detergent SAE30 weight motor oil can be used. The use of 
a vegetable based bar and chain oil is recommended when 
pruning trees. Mineral oil is not recommended because it 
may harm trees. Never use waste oil or very thick oil. These 
may damage yourchain saw.

chain oil until the oil level has reached the top of the oil 
level indicator
