LOW TEMPERATURES At low temperatures it is 400 - HB 440 recommended that the tools be heated before use and if it is possible use at low speed for a progressive increase in temperature of the machinery.
CORROSION Rust or corrosion on the tool occurs when the tool is stored outdoors and it is not - 440 HB 400 well lubricated. This can be avoided by simple and easy lubrication and maintenance of hammer’s tool away from moisture when not in use.
