4. Operator Maintenance
This chapter outlines machine maintenance; in addition, operators and maintenance personnel
must attend a Melco approved training course prior to maintaining the machine.
Installing a Needle
Each needle has a needle clamp set screw hold-
ing it in place as shown in Figure 4-1. Use the
small flat-blade screw driver from the tool kit
and follow these steps to replace a needle:
1. Turn the set screw counterclockwise until
the needle can slide down and out of the
needle bar. Do not remove the set screw.
2. With the scarf of the new needle toward
the rear of the head, slide the needle into
the needle bar as far as it will go, and re-
tighten the set screw. The eye of the needle
should be facing directly forward.
Thread Break Switch
Each head has a thread break switch below the tensioners with
(ON),
(AUTO), and
(OFF) positions (see Figure
4-2). The switch controls whether the individual head stitches as
it moves through a design. The table below summarizes the
functions of the switch.
