A grease gun comprising a body having first and second chambers, first and second pistons within those first and second chambers, primary and secondary grease channels, a grease outlet and an actuator, is provided. Actuation of the actuator by a user causes first and second pistons to move within first and second chambers. The body may further comprise a pressure sensitive spool which allows the grease gun to move from a high flow/low pressure operation to a high pressure/low flow operation when there is a grease blockage that causes an increase in the pressure in the body.

A system for determining an oil amount in a marine drive includes an oil level sensor that senses an oil level in the sump and temperature sensor sensing an engine temperature. A control module for the system is configured to determine that the engine temperature is greater than a temperature threshold, and that an engine speed exceeds a speed threshold for at least a predetermined time period or that a throttle position exceeds a throttle position threshold. If both such conditions are met, and a threshold drop in engine speed to an idle threshold is detected or a threshold change in throttle position to an idle position is detected, then an oil level in the sump is sampled with an oil level sensor. An oil amount is then determined based on the sampled oil level in the sump.

A lubricant delivery system and method includes a valve manifold, an electronic controller, and a pressure sensor for determining whether there is adequate lubricant flow in the system. The valve manifold receives lubricant from a pressurized source. The valve manifold includes a plurality of valves configured to control the flow of lubricant to respective applicators. The electronic controller controls the opening and closing of the valves. The pressure sensor measures lubricant pressure in the valve manifold, and outputs a signal to the electronic controller. The signal correlates to a lubricant pressure value in the valve manifold. The electronic controller uses the lubricant pressure values to derive an indication of lubricant flow (via the valves) to the applicators.

Disclosed is a method for delivering a lubrication liquid to a machine in a terminating liquid lubrication system. A machine and a cartridge containing a lubrication liquid are connected to each other so that the lubrication liquid is supplied to the machine. Some embodiments may include a monitoring system, a backup source of lubrication liquid, and/or a second cartridge that automatically provides lubrication liquid to the machine when the cartridge is empty.

A coupling element for a machine tool attachment, having a coupling section for detachable mounting on a tool interface of a machine tool and having a connection for attaching a container for media that has an outlet and holds a medium. In addition, a machine tool attachment, a machine tool, and a method for delivering a medium to a part of a machine tool is provided.

A system includes a machine tool that includes a cutting tool, a fluid subsystem that provides fluid to the cutting tool, and at least one processor that executes instructions that cause the at least one processor to: obtain a signal indicative of a load on the cutting tool, establish a first value of at least one parameter of the fluid based on the signal, obtain a second value of the at least one parameter that is based on a simulation, determine a difference between the first value and the second value, and adjust a state of a device of the fluid subsystem based on the determined difference.

A method for determining lubricant consumption by a transmission mechanism disposed on a machine tool includes steps of: a) estimating, based on an operational speed and a predetermined first predictive model, a total operational physical quantity; b) estimating, based on an individual operational physical quantity and the total operational physical quantity, a total operational count; c) receiving actuation information from the machine tool, and calculating a partial operational count based on the actuation information; and d) calculating, based on the partial operational count and the total operational count, a ratio between an amount of lubricant consumption within a time period and a total amount of lubricant.

A system includes a tool including a communication module configured to transmit first data related to maintenance of an asset, and an intermediary computing device in communication with the communication module. The intermediary computing device is configured to receive an image of the asset, a maintenance point thereof, or both, transmit the image or video to a remote server, wherein the remote server is configured to verify an identity of the asset, the maintenance point, or both based on the image or video, receive the first data from the communication module, transmit the first data to the remote server, and receive second data representing a maintenance action to take on the tool, the asset, or both from the remote server.
