The 1490749-1 is a Compression Tool intended for occasional use and low volume applications. The hand tool has a stationary lever and a movable lever. These levers are compressed to pump hydraulic fluid behind the ram, moving it forward and thereby closing the dies. After the crimping is complete, the movable lever is turned to depress the plunger. The moving die retracts to its original position, completing the crimping cycle. Manual power type Applications Maintenance & Repair
