1. Remove old oil wick holder as instructed above.
2. Remove top arm plugscrewJ3, Fig.25.
3. Insert two oil wick leaders into oil tube K3, as shown in Fig. 25sothat wick is slack over edge ofoil tube K3 at
point L3, Fig. 25. This will insure free passage of oil. Use tweezers through the screw hole at J3 to loop the wick
and bring it into positive contact with the arm shaft approximately at point M3 shovm in Fig. 25.
NOTE: DO NOT FORCE the wick leaders down too tightly against the edge L3 of oil tube, as shown in Fig. 26,
as this will decrease the flow ofoil from the arm shaft to the needle bar link and take-up bearings.
CAUTION: If the bottom of either oil wick leader is caught on the ledge as shown at N3, Fig. 27, no oil can be
taken up by the wick to be carried to the needle bar link and thread take-up bearing, where it is needed. Make sure
that the oil wick leaders are pushed all the way down into the smaller hole, without jamming, untU they touch the
arm shaft, as shown in Fig. 25.
