(Trial operation)
1) Operation when the power is turned ON
When turning ON the power switch, the sewing machine rotates up to the needle-up position excluding the
case where the needle position at that time is the position other than the up-stop position and stops at needle-
up position.
2) Pedal operation
Pedal can be operated in four steps.
①
The machine runs at low sewing speed when you lightly depress the front part of the pedal.
②
The machine runs at high sewing speed when you further depress the front part of the pedal. (However, when
the automatic reverse feed stitching switch is preset, the machine runs at high speed after it completes reverse
feed stitching.)
③
The machine stops (with its needle up or down according to the set of stop position) when you reset the pedal
to stop (neutral).
④
The machine trims threads and stops with its needle up when you fully depress the back part of the pedal.
○
The machine will completely perform thread trimming even if you reset the pedal to its neutral position
immediately after the machine started thread trimming action.
At this time, if you depress the front part of the pedal instead of neutral, thread trimming is performed
normally. However, safety circuit works and the machine continues to stop after completing thread trimming.
At this time, return the pedal to the neutral position once.

Wiper works when the wiper is provided (WB type).
