ADJUSTMENT AND OPERATION OF CONTROL UNIT
I 4 I Adjusting the Operating Speeds
1 Adjusting the maximum speed (speed available with the pedal fully toed)
Two variable resistors are available for adjustment of the maximum speed;
one Is located In the control box
and the other on the control box panel. The external variable resistor (knob) allows adjustment between
low speed and the maximum speed set bythe Internal variable resistor H.The internal variable resistor H
Is factory-set as follows:
Internal Variable Resistor H Setting
External Knob Adjustable Range
2000spm
Low speed to maximum speed.
I
To set to any speed outside the above range, adjust the Internal variable resistor H, using a speed meter.
CAUTION
The speed set by the internal variable resistor H and external knob cannot be exceeded if a larger
motor pulley is used.
I
2. Adjusting the low speed (speed available with the pedal slightly toed)
The low speed Is adjustable with the internal variable resistor L. Clockwise turn Increases the low speed
and counterclockwise turn decreases. The speed Is adjustable between 1 60 and 320spm factory-set
to 250spm).

3. Positioning speed
The positioning speed can be adjusted by the internal variable resistor P (factory-set to 250spm). Turn it
clockwise to Increase and counterclockwise to decrease, the adjustable range is 160 to 320spm.
4. Adjusting the thread trimming speed
The thread trimming speed can be adjusted by the internal variable resistor T. Turn Itclockwise to increase
and counterclockwise to decrease, the trimming speed Is factory-set to 1 75spm and may depend on the
sewing machine used. When adjusting this speed, refer to the sewing machine adjusting manual of
contact the service agency.
5. Adjusting the backtacking speed
When any on the control switch panels (option) Is used for backtacking, the backtacking speed (medium
speed) Is adjustable with the internal variable resistor M.
