and spray it with dry lubricant. Grease the threaded
spindle.
4. Check the clamping of the tailstock and tool rest and
readjust if necessary.
5. Check drive belt and replace if necessary. The check

hours.
10.3Servicing
As a result of wear and tear, servicing work may have to
be carried out on the machine.
Lubrication
The belt cover must be removed to lubricate the shift and
drive shafts. Only an adhesive grease may be used for
this, as it can otherwise lead to malfunctions of the belt!
Guides, quills and bearings must be lubricated with com-
mercially available grease!
The points to be lubricated are shown in Figure 17.
