Lubrication:

has a grease-packed lubrication system. It should be relubri-
cated after every 6 months of operation. Send the complete
tool to an Authorized Service Center for this service.
If circumstances require that you must lubricate the tool
yourself, proceed as follows:
1. Switch off and unplug the tool.
2. Use a screwdriver to remove the four screws with washers
(113) from the plate (111). Remove the plate. See Figure 10.
