If there is not yet power on the jobsite available, or the electrical part of the unit is not finished, you must move the unit by hand using the handwheel every time 50 mm to avoid that the step chain wheels and step wheels get flat spots. In this case, the tension carriage springs should be released until the springs are completely slack and you should keep it this way until you start running the unit with power.,68,PDC XIZIOTIS,Preventive Maintenance,Remember that on glass balustrade-units the pressure rollers of the friction wheel drive system are after the test run in the factory released and should remain this way until the unit is prepared for handover, thus avoiding the rollermarks on the handrails. On units directly exposed to the weather you should be even more carefully, they require more frequent oiling due to the frequent rain. In wintertime with temperatures below 0° Celsius you must start the heating at least one hour before you begin with the maintenance to warm up the handrails and the unit. If there is snow on the steps you must remove it before you move the unit, otherwise you will certainly destroy the combs.,
