Sewing speed and rotating direction of pulley
Table 4 shows maximum sewing speed and usual speed for
each model.
Run a new machine at speed about 15 - 20% lower than
maximum speed during the rst 200 hours (for about one
month) so that a machine can offer a long service life in
good condition.
The rotating directions of the machine pulley ① and the
handwheel ② are clockwise as shown in the gure.
Fig. 3-1
If rotated in reverse direction, oil cannot be supplied
properly. It can cause the damage to the machine.
