Oil felts in needle unit
Oil-impregnated felts provide a constant supply of oil to the needle bars. The felts must
be oiled every three months (the interval is to be shortened accordingly in the case of a
two or three-shift duty cycle).
• To oil the felts, the front panels do not have to be taken off the embroidery heads. The
upper threads can also remain threaded..
