Abstract:
1. A device for use with a battery and a cartridge of lubricant, said device for dispensing the lubricant in the cartridge at a lubrication point, said device comprising: a handheld housing enclosing the following in a unitary structure: a pump mechanism configured for communication with the lubricant in the cartridge and having a supply port for dispensing the lubricant at the lubrication point; an electric motor for driving the pump mechanism to dispense the lubricant; a power supply for connection to the battery; a sensor configured to monitor at least one of the pump mechanism and the electric motor, said sensor generating a condition signal indicative of the operation of the monitored pump mechanism and/or the monitored electric motor; a display configured to display information indicative of the monitored condition of the device; a processor responsive to operator input for controlling the power supply to selectively energize the electric motor to drive the pump mechanism to dispense lubricant at the outlet of the pump mechanism, said processor connected to the display, said processor connected to the sensor for receiving the conditional signal and responsive to the condition signal for selectively energizing the electric motor and for controlling the display to provide a visual image to the operator corresponding to the condition signal; an input device connected to the processor and responsive to operator input for providing information to the processor; and a battery temperature circuit providing a battery temperature signal indicative of a temperature of the battery, said battery temperature circuit connected to the processor, wherein the processor is configured to energize the electric motor to drive the pump mechanism to dispense lubricant at the outlet of the pump mechanism only when the battery temperature signal indicates that the temperature of the battery is below a maximum temperature; and wherein the input device comprises one or more keys, wherein the processor is programmable by the operator via the one or more keys with information indicative of the initial volume of lubricant in the cartridge when the cartridge is installed by the operator.
