Which statement describes how oil is picked up in the Ematic Bar Lubrication System?

• A. Oil is picked up by gravity from the guide rail
• B. Oil is picked up by passing chain
• C. Oil is drawn from a reservoir on the bar
• D. Oil is sprayed from the engine

Answer: (B)

The key idea here is how lubrication oil actually gets into the path where the chain contacts the bar. In the Ematic Bar Lubrication System, oil is delivered into the bar and then the moving chain does the work of taking it up and carrying it to the points that need lubrication. As the chain turns, it interacts with the oil contained in the feed path of the bar, effectively scooping or picking up the oil from that supply and distributing it along the bar where the chain runs. This design ensures oil is delivered directly to the chain and bar contact areas right as they work, rather than relying on gravity or a spray from the engine. That pickup-by-the-chain idea explains why this mechanism is preferred: it provides consistent lubrication no matter how the saw is oriented during use, and it keeps oil delivery tightly focused at the chain’s contact points. The other descriptions would not reliably describe how Ematic feeds oil to the chain path, which is why they aren’t correct descriptions of the system.
