LUBRICATION

Five/ten drops of oil for

one oiling are necessary
only in this portion.

As special materials (oil impregnated metal) are
used for parts of this machine actual additional

lubrication is negligible. However, since oil wick

is provided for the inner sections, oil should be

provided no more than once or twice per month

to those parts (6 Positions) marked in red which

can be seen from the outside of the machine, in

addition to those parts (5 Positions) shown in

Figure 49. 1-2 drops of oil is sufficient for one

oiling.
