CAUTION: HANDLE WITH CARE.
To ensure our customers receive all components with full integrity, we pack
the motors separate from their Linkage assemblies. This requires that the

Please follow the instructions below and handle the assembly carefully.
CAUTION: Dropping the assembly or any excessive impact MAY cause
damage to the motor.
Instructions:
1. Position the gear cover in place as shown if not already in place.
2. Seat motor into position on the three mounting bosses. This may require
an adjustment of the gear by moving the swing arms.
3. After seating into place, fasten the motor with the three motor mount
screws with 4mm Hex Head. Tighten screws to 36 in-lbs (4N-m). Do not
over torque.
