Abstract (en)
[origin: CA3200706A1] The invention relates to a mobile machine tool, in particular a hand-held machine tool (10) or a construction robot, for example for carrying out work in construction and/or civil engineering applications, comprising a drive unit (20). The mobile machine tool is characterized in that the drive unit (20) has an aqueous lubricant (26) and/or in that the drive unit (20) is designed to operate with the aqueous lubricant (26), wherein, prior to a running-in phase of the drive unit (20), a composite roughness sigma of two cooperating contact surfaces (22, 24) of the drive unit (20) is greater than 0.01 pm, preferably at least 0.1 pm. The invention also relates to a method. The invention improves energy efficiency.
