A grease gun is a common workshop and garage tool used for lubrication. The purpose of the grease gun is to apply lubricant through an aperture to a specific point, usually from a grease cartridge to a grease fitting. Keep your face away from the discharge port to avoid spraying. Some undesirable things such as machine dust and chemicals may spew out if you stay close to the tool.
