3.13 Lubrication
3.13.1 Description
From the lubricating tank (1) there issue three suction wicks.
The wick (2) lubricates the pin of the thread mechanism, the
wick (3) lubricates the needle mechanism and the wick (4)
lubricates the stitch length mechanism. The superfluous oil
from the needle and thread mechanisms is sucked off by the
wick (5) and lubricates the shifting wedge of the feeding
clutch.
The hook has its own oil reservoir (6). The superfluous oil
from the hook lubrication lubricates the driving gear of the
hook.
3.13.2 Refilling oil
For lubricating the machine oil Esso SP-NK 10, DA 10 is used
or other oil with the same quality. When putting the machine
into operation, each mechanism of the machine is to be
lubricated with several drops of oil. Oil is only refilled thereafter
into the oil reservoirs using an oil can into the holes in the oil
level indicators.
The oil tank (1) of the central distribution is to be filled up to
the mark max.
The oil tank (2) of the hook lubrication is to be filled up to the
upper edge.
3.13.3 Multiple oil use
Oil which runs into the oil cup is collected in the collector (1)
and may be reused for refilling the oil reservoirs in the machine
- see par. 3.13.2.
The oil collector (1) with the collected oil is uscrewed and the
top part of the oil can (2) which is added in the machine
packing is screwed in. Oil is then refilled into the reservoirs on
the machine head and everything is put into the original
condition.
