  • GREASE GUN WITH PUMP PRIME INDICATOR
    Publication number: 20210140584
    Abstract: A grease dispensing device includes a grease drive system for moving grease through grease passaging. A sensor is arranged to sense grease in the grease passaging and to generate sensor data related thereto. After a delay period, a prime indicator changes between first and second states based on the sensor data to indicate whether or not the grease dispensing device is primed with grease. The grease dispensing device also includes a grease controller operatively connected to the sensor and the prime indicator. The grease dispensing device monitors the sensor data to determine whether the grease dispensing device is primed with grease and controls the operation of the prime indicator accordingly.
