Open the feed motor cover, there are 4 grease inlets on the elevating nut
of saw arbor.

Grease Lubrication

Note the following precautions whenever using grease lubrication.

◎

Select the proper grease. For examples of the main types of grease used for
machine tool bearings, see Table 4-2.1.

◎

Make sure the grease replenishment amount and locations are correct. A
greasing amount of 10 to 20% of the bearing internal space volume is
recommended for high-speed roller bearings. Note, however, that 40 to 50%
is recommended for a ball screw support bearing (open type).

◎

Over-greasing can result I very high temperatures and large power loss due to
agitation. For information about internal space volume of bearings, see Table
4-2.2.

◎

For an example illustrating the difference in bearing temperature increase due
to lubrication method, see Figure 4-2.1.
