When does the BEAR Power Unit utilize the pre-lubrication pump?

The pre-lubrication pump in the BEAR Power Unit is utilized during startup to ensure that the engine components receive sufficient lubrication before the main oil pump takes over. This process is crucial because it helps prevent wear and tear on engine parts by circulating oil and reducing friction in the system as the unit is powered on. By providing lubrication from the moment the engine starts, the pre-lubrication pump contributes to a smoother transition and ensures that all critical moving parts are protected properly from the outset. This is particularly important in maintaining the longevity and reliability of the power unit.
