Saw Chain and Guide Bar Oiling (Fig. I)
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 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 yourchainsaw.

the reservoir with the recommended bar and chain oil
until the oil level has reached the top of the oil level
indicator
