Lubricate ball oilers (A, Fig. 4) found by the X/Y-
axis hand wheels, the oiler found by the
raising/lowering crank handle, and the oiler on
the front of the bed once daily with Mobil DTE
Oil Heavy Medium.
Lubricate the ways (B, Fig. 4) once daily with
Mobil DTE Oil Heavy Medium.
If the head does not raise, or lower smoothly
apply Mobilith AW2 to the rack, and Mobil
DTE Oil Heavy Medium to the column.
If the feed handles do not turn smoothly apply
Mobilith AW2 to the cross, and longitudinal lead
screws (C, Fig. 4). Access the cross lead screw
by moving the table forward and removing the
way cover.
The spindle bearings are permanently sealed
and require no lubrication.
