In the Ematic Bar Lubrication System, how is oil delivered to the drive links?

• A. Two ramps on the guide bar rail direct lubrication to drive links
• B. Oil is picked up by passing chain
• C. Oil is sprayed from the exhaust
• D. Oil is not used

Answer: (A)

The basic idea is to deliver lubrication exactly where friction is highest. In the Ematic Bar Lubrication System, oil is guided directly to the drive links by two ramps machined into the guide bar rail. As oil is pumped through the bar’s channels, these ramps funnel it onto the drive links, ensuring consistent lubrication where the chain engages the sprocket. This targeted delivery reduces wear and heat on the drive links and bar. Other concepts like oil being picked up by the passing chain, oil sprayed from the exhaust, or using no oil don’t describe how Ematic actually delivers lubrication to the drive links.
