134. Start-up and maintenanceAfter the machine has been professionally installed and securely mounted, it must be connected tothe mains supply.1. A qualified electrician must connect the supply lead of the drilling and milling machine to thelocal power supply.2. Provide sufficient lubrication coolant for running the coolant unit(optional).3. All functions must be checked.In order to clamp workpieces a machine vice or clamping screws (suitable for the T grooves) maybe used.Greasing the milling machineEvery 6-8 weeks the Quill and the feed pinion should be greased (see sketch).Therefore move the quill up and down while applying some lubricant to the lateral metal-on-metalcontact area of the quill and the feed spindle.It is not necessary to lubricate the drilling spindle, as the ball bearings are fully enclosed and hadbeen lubricated during production for the entire service life of the machine.The milling machines with linear guides are maintenance-free and do not need greasing.Lubrication means: - reducing the wear and the frictional resistance- extending the lifetime- preventing the metal surfaces from corrodingWe recommend: for lubrication: multi-purpose grease grade 2NLGIfor oiling: lubrication oil of 100 mm 2/s viscositySpindle nuts with trapezoid thread spindle:The spindle nuts of the milling machines are adjustable.Should a spindle nut of one of the three axes have some play, proceed as follows:
