PSM21 Repair and maintenance Repairs Powertool Systems Instructions for the PSM21 drill feed unit Repairs are conducted by PSM employees or other authorised specialists. We support authorised specialists by sending repair instructions or support by telephone. Caution! As a basic principle, repairs within the warranty period are performed by PSM. Maintenance Visual inspection and cleaning should be performed at regular intervals. To make this easier, the enclosure must be dismantled from the base unit. After they have been removed, all the main groups will be open and able to be checked for signs of damage. The pictures below help how the enclosure is dismantled: Fig. 16.10 Fig. 16.11 Fig. 16.12 Fig. 16.12 Fig. 16.13 Fig. 16.14 [Fig. 16.10] Unscrew two screws (M6) on each of the two fixing plates.
