1 Warning Caution: • Pb free solder has a higher melting point that standard solder; Typically the melting point is 50 - 70°F (30 - 40°C) higher. Please use a soldering iron with temperature control and adjust it to 750 ± 20°F (400 ± 10°C). In case of using high temperature solder- ing iron, please be careful not to heat too long.
5 Disassembly and Assembly Instructions 5.1. Disassembly Instructions Ref. No. 1A Procedure 1A Removal of Fixation cover. 1. Remove four screws where tightening fixation cover. 2. Pull off the fixing cover assembly. 3. Once removing the fixing cover, the driving shaft assembly may come out.

Procedure 1A 1B 1C Ref. No. 1C Removal of Housing. 1. Remove nine housing screws. 2. Then open the housing A and B. NOTE: When opening the housings, make sure that the main PCB is on the housing A. If the main PCB sticks in the housing B and pull it out from the hous- ing A, the ribbon cable may be defected.

Procedure 1A 1B 1C 1D 1E Ref. No. 1E Removal of Motor assembly. 1. Separate the motor assembly from the driving shaft assembly. 2. Take out the motor rotor assembly from the motor stator. NOTE: Make sure not to damage the magnet by motor rotor. NOTE: Make sure not to scratch FET circuit by motor rotor.

Procedure 2A 2B 2C Ref. No. 2C Assembly of Switch and Motor assembly. 1. Attach the quick connect terminal of the white lead wire from the motor stator with the switch assembly (M+). 2. Apply grease (FLOIL AH-137N-2 / WEWGW2) on the both side and both end of ribbon cable where insert into the connectors.

Procedure 2A 2B 2C 2D Ref. No. 2D Assembly of Driving assembly. 1. Confirm to attach the fixing rubber on Housing B. 2. Insert the motor and driving shaft assembly into the housing. 3. Confirm to set the motor lead wire (white) under the black lead wire and confirm if there is no pinching with switch.
6 Measurements and Adjustments 6.1. Trial Operation (after checking Troubleshooting Guide.) A. ASSEMBLY Confirm if there is NO gap between Housing A and B by pinching the lead wires. Confirm all screws are tightened firmly. Confirm if there is no deformation on the battery terminal. B.
