• Make sure that the lifting slings

• Make sure that the lifting slings can be changed easily at the roll ends.• Surface temperatures of the thermo rolls can be almost 200°C.• When changing oil couplings, beware of the oil in the hose and roll.• NO WATER on thermo roll surface!1.5 PREINDICATING MAINTENANCE AS A PART OF OCCUPATIONAL SAFETYPreindicating maintenance has a very important role in the machine safety. A machine or device in bad condition due to lock of maintenance and inspection forms a safety risk to its user. For example, one bearing left without lubrication can get broken and break the machine. This can cause severe danger. A bearing without lubrication heats up and causes danger of fire.In the preindicating maintenance of the paper or finishing machine, attention should be paid to the following points, which have an effect on the machine safety.• Obey the maintenance and lubrication instructions of the machine manufacturer. The operating and maintenance instructions (interleafs 5,6,7 and 8) specify regular maintenance and lubrication measures.• Keep the machine clean and tidy.• Follow the vibration of the machine and rolls, increasing vibration level indicates bearing damage.• Follow the current consumption of motors, increase in current consumption can be due to a latent fault.• Repair all leakages for example, water or air leakages as soon as possible.• Follow the condition of pipes and hoses, and repair possible leakages.
