The present disclosure relates to a lubrication monitoring system (15) configured to monitor a supply of lubricant in a hand-held cutting tool (1) having a cutting unit (3, 5). A lubricant tank (41) and a conduit (45) are configured to duct a flow of lubricant from the tank (41) to the cutting unit (3, 5). The lubrication monitoring system (15) comprises a heating element (29) and a sensor arrangement (31, 33), the heating element (29) being configured to heat the lubricant flow. The sensor arrangement comprises a first sensor (31) located at the flow, upstream of the heating element (29), and a second sensor (33) located at said flow, downstream of the heating element. The lubrication monitoring system outputs a monitoring signal based on a sensed temperature difference between the first and second sensors (31, 33).

A lubrication/bleeder fitting (10) is provided including a cap (14), a body (12) having a first end (15) coupled to the cap, a second end (17) opposite the first end, and an axially extending cavity (40) extending between the first and second ends. The fitting also includes a poppet seat (50) in the axially extending cavity and a poppet (60) disposed in the axially extending cavity and having a nose portion to seat against the poppet seat. A resilient member (64) is disposed in the axially extending cavity between the poppet and the second end, and a spacer (66) is disposed in the axially extending cavity and seating an end of the resilient member opposite the poppet. The poppet is biased in a first position against the poppet seat by the resilient member to prevent fluid flow through the axially extending cavity.

Systems, apparatuses, methods, and computer program products are provided herein. For example, a method provided herein may include identifying oil pressure data associated with an engine. In some embodiments, the method may include generating adjusted oil pressure data by adjusting the oil pressure data by an engine speed or an ambient pressure. In some embodiments, the method may include generating, by applying the adjusted oil pressure data to an oil pressure residual model, oil pressure residual data indicative of one or more oil pressure residuals. In some embodiments, the method may include generating, by performing a windowing operation on the oil pressure residual data, erratic oil pressure data for a carbon seal associated with the engine. In some embodiments, the method may include initiating performance of one or more responsive actions based at least in part on the erratic oil pressure data.
