3.14 Lubrication

3.14.1 Description

In  the main lubrication  reservoir (1) there is a suction wick (2)

which wipes against the shaft (3). The wick (4) collects oil

from the shaft (3) and feeds it into the wick (5) which

distributes oil to the lubricated spots. The left branch lubricates

the needle and the thread mechanisms. The right branch

lubricates the mechanism of the stitch length and, thereafter,

pushed into the box (11). The wick (6) sucks off the excessive

oil from the needle and the thread mechanisms and also

pushed into the box (11). The lubrication reservoir (7) feeds

oil through the wicks (8) for lubricating the hooks. The wick

(9) lubricates the shifting wedge of the feed clutch. The wicks

(10) lubricates the gears of the hooks drives.

3.14.2 Refilling oil

For lubricating the machine oil Esso SP-NK 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 reservoir (1) is to be filled up to the

half of its content. The oil reservoir (2) is filled up to the pouring

holes.

3.14.3 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. 3.1.4.2.

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.
