DANGER
Secure the arm system before removing any
motor! The brake is located in the motor and
is therefore released when the motor is re-
moved!
Remove the armhouse cover.
Remove the strap and disconnect the motor
connectors.
Unscrew the attachment screws securing the
motor.
Use a 300 mm extension for bits 3/8".
Remove the motor by lifting it carefully
straight out, making sure the motor pinion is
not damaged while moving it away from the
gear.
