The tool also includes one or more charges disposed in the charge chamber. The one or more charges are configured to ignite and thereby expand a gas in the charge chamber. The tool further includes a fluid-metering device coupled to the housing. The fluid-metering device is configured to control a rate at which the hydraulic fluid is pressed out of the hydraulic chamber.
