DISCONNECT TOOL FROM POWER SOURCE.
1. Remove collet nut and collet from motor unit.
2. Assemble drive pulley (A) Fig. 7, to motor spindle and tighten securely.
3. Use a phillips screwdriver to remove the three sub-base mounting
screws (A) Fig. 8, from the base, and remove the sub-base.
4. Position the base to the motor and drive pulley assembly (from
step 2). Be sure that the motor drive pulley engages the drive belt (inside the
base housing).
5. Secure the motor to the base (see Fig. 9), with the thumbscrew (A),
spring (B), and washer (C).
