Adjusted to the correct running-oil-level, the LR857 will replenish oil as it is used. An integral, low-level switch will alarm and/or shutdown the equipment if supply oil is lost and the equipment continues to use oil. The LR857 maintains oil level on any size engine, but is recommended for small to medium volume applications and installations that require a 3-wire, snap-action switch. As crankcase oil level drops, the LR857 float also drops and opens the Thumb-Valve. This allows oil to flow from the supply tank, through the LR857, and into the crankcase. When the proper level is attained in the crankcase, the LR857 float rises, causing the Thumb-Valve to close off further oil flow. Flow rate through the 1/8" (3 mm) orifice is sufficient to allow crankcase refill through the LR857.
