4.2 Fastening the motor

Screw the base of the motor to the table

top. To do this, turn the 3 hexagon head

cap screws M8 x 35 with the washers into

the inserts of the table top.

Fasten the potential sheet 3 such that it

touches both, the motor base 1 and the

hinge 2. The potential sheet conducts

static charges of the machine head via

the motor to the earth.

Fasten the V-belt pulley to the motor

shaft.

Check the arrangement of the terminals

in the transformer of the sewing machine

motor, and if necessary, change. The

arrangement must be adapted to the

voltage supply.

5. Mounting the machine

head, positioning the

V-belt and fastening

the pedal

Mount the machine head in the table top.

Position the V-ripped belt.

Adjust the tension of the V-ripped belt.

To do this, change the position of the mo-

tor with respect to the sewing machine

such that the V-ripped belt can be

pressed inwards by approx. 10 mm

without great effort.

Screw on the belt guard, and thereby set

its belt retainer cam such that the belt

stays in the V-belt pulley when the

sewing machine is tilted backwards.

Screw the belt guard to the machine

head.

Mount the pedal and rods.

For ergonomic reasons, the pedal is to be

aligned laterally and centred with

respect to the needle.

Adjust the rods such that the released pe-

dal is sloped by approximately 10 °.
