Lubricating
Since

the

are
fitted with
alternating
pressers,
they
have
a
num
ber of additional oiling points which are marked by arrows in Figs. 22 and 23. Of these,
particularly the points of friction at the needle-bar-end of the machine, such as the
needle bar (inside needle bar frame in Fig. 22) and the sleeve take-up with its round
shank (behind needle bar in Fig. 22), require thorough and regular lubrication.
All
moving and rotating parts should be oiled regularly. To prevent soiling of the work
through dripping oil, sew a few seams on a piece of scrap material to absorb all ex
cess
oil.
Never try to remedy certain faults by applying excessive quantities of oil. Excessive
