Images filling the blower resevoir with oil

Since there is no easy way for the blower's oil resevoir to vent when you are adding oil, it can take a really long time to trickle in. If you wait to attach the upper hose to the blower, then it has a place to vent and the oil pours in much quicker (in several seconds rather than several minutes). Make sure that the end of the hose is above the level of the oil lest you make a mess.
