GeneralInstructions for Using DCZ-361
1. SewingSpeed
The maximum speed for this machine is 5500 stitches per minute but the optimum speed recommended for
daily operation is 5000-5200 stitches per minute.
In starting a new machine, it is advisable to run it at the optimum speed after operating it at 4500 stitches per
minute for about 200 hours (i.e., about one month), as it will greatly help prolong its life.
2. Installation
Fig. 1 shows the measurements for installing this machine. The standard position for installation is a submerged
one. But the non-submerged installation is also practised. As we have always the tables and ancillary parts for
the submerged installation in stock for customers who wish to have these articles together with the machines,
your order for them will be promptly executed.

4. Lubrication
As the oilhasbeencompletely drained from the machine beforeshipment,be sureto fill the oil reservoir be
fore starting operation through theoil hole removing the screw indicated by "OIL" mark. Filloil until the oil
level comesup to the upper lineHon the oil gauge shown in Fig.4.
Be sureto check the oil gauge before starting operation everyday. If the oil level isbelow the lower line L,
fresh oil should be replenished. After replenishing, replace the screw.
In order to keep the machinelife longer,it is advisable to changeoil completely after operating a new machine
for 250 hours or so.

DRAIN
Fig. 3 Fig. 4
To change oil, drain the used oil out of the reservoir by removingthe drain screw(A, Fig. 4) situated below the
balance wheel. The drain hole is indicated by the mark "DRAIN".
Anoil filter net isfixed to the pump F insidethe machine. Cleanthis net and the insideof the base two or three
times a year. To do this, the base must be separated from the machine frame. To remove the base, drain the
oil completely out of the reservoir,tip the machine backwards and remove the set screws. When the cleaning
hasbeen finished, fix the base togetherwiththe packings to the machine securely. When the oilstay the space
between the machine base and the machine, theseoil can be drainedby removing thescrewC.(Fig.4)
5. Rotating Direction of Balance Wheel
The balance wheel should turn to the right or clockwise when facing the balance wheel.
6. Needles
DC X I needle is used for the right needle and DM X 13for the left needle. There are manysizesfor them and
proper size needles shouldbe selected according to the kindof workto be undertaken. Generally speaking, #9
isthe standard size for sewing light weight fabrics, #11 for medium weight and #14 for heavy weight.
7. Setting Needles
Turn the balance wheel away from youuntilthe needle bar reaches the highest position, pull the presser bar
litter Ain theairov direction and swing out the presser foot Bto the leftas shown in Fig. 5. Loosen the needle
set screw C. insert the needle inthe holder as far as it will go with it scarfed side (nota long grove) at the back
and then tigliien the screw.

9. Thread Tension for Double Chainstitch Seam
Figs. 7 and 7-1 show the relation between the needle thread guides A and B. The position ofB is right when
it is at the height below the highest point of the guide Aby1/4of its stroke (same as the needle bar stroke).
To make the tension onthe needle thread lighter, move this thread guide B upwards a little and to make heavier,
move B downwards a little. But it should be noted that too much raising or lowering of this guide often causes
thread breakage.
In almost all cases, the needle tension may be satisfactorily adjusted by turning the tension adjusting cap.
