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
10
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 finishedcutting.
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 yourchain saw.
Filling the Oil Reservoir
1. Unscrew counterclockwise and then remove the oil cap
16
. Fill the reservoir with the recommended bar and
chain oil until the oil level has reached the top of the oil
level indicator
10
.
2. Refit the oil cap and tighten clockwise.
3. Periodically switch the chain saw off and check the oil
level indicator to ensure the bar and chain are being
properlyoiled.
