Specifications
Direct Drive Installation
Install control box and speed controller as gure below.
Using screws, mount the control box and speed controller onto sewing table.

Direct Drive Motor Installation:
1. Rotal Installation
a) Remove the hand wheel, belt cover and wind blade on the sewing machine
b) Install the Fan blade (gure 1) and rotor (gure 2) into the shaft of sewing
machine as seen above. Secure parts into place with washer (gure 3) and
screws (gure 4 & 5).
2. Motor Installation
Using a special plastic positioning jib (gure 6), install into sewing machine over the
rotor (gure 2) directed then secure with screws (gure 8). Screw down to be able
to easily pull out the positioning sleeve. (Note: Use caution when installing and pay
attention to the magnet suction, as this can cause injury to hand).
3. Check Rotar & Stator Installation
a) Remove rubber hole stopper (gure 9).
b) Check the plane of the rotor and ensure the stator is at, surface should not
exceed 1.5mm (See section gure A). If area is more than 1.5mm, remove the
motor and the rotor with gasket to adjust (gure 11).
c) Adjust to t back rubber hole stopper. (Note: The distance between the two
should be as small as possible. If more than 1.5mm, motor torque will
decrease).

4. Hand Wheel Installation
a) Turn the sewing hand wheel by hand ，make the needle stop at the highest level
b) Put the hand wheel in the rotor, and mark the calibration line of the motor housing with the
scale 5 (Figure B).
1.5mm- 2.5mm (Figure C). (Note: Overlock machines will have three little strips (Figure D).
