Assemble right shoulder base

1. Shoulder joint assembly
   Tip 【SM03 Servo Motor (ID03)】 into 【F7 Shoulder joints (base)】 with splined shaft facing as shown.
   Before installation, return servo motor shaft to zero position!
   How to return servo motor axle to zero position?
2. Slide splined 【H1 Servo motor wheel (main)】onto shaft, and insert its lock tabs into matching slots so it sits flat on F7 part. Secure with machine 【Screw No. 4 (M2_L6 MW20060)】.  If shaft is not at zero, you will not be able to insert it into wheel.
3.  Turn part over and place 【H2 Servo Motor Wheel (auxiliary)】 over other end of servo shaft. Secure with 【Screw No. 5 (M2_L6 TW20060-2)】. Note that all servo motors are installed in this fashion using a machine screw on splined end and a self-tapping screw on the other.
4. Rotate【F7 Shoulder joints (base)】 90 degrees clockwise making sure it moves freely and there is no play in the joint.
5. Right shoulder base assembly complete!

02-2 Assemble left shoulder base

Required Parts:

SM07 Servo Motor (ID07) x1	F7 Shoulder joints (base) x1	H1 Servo motor wheels (main) x1	H2 Servo motor wheels (auxiliary) x1
