Refitting, motor
The procedure below details how to refit motor, axis 3.
Please observe the following before commencing any repair work on the manipulator:
- Motors and gears are HOT after running the robot! Burns may result from touching the
motors or gears!
- Turn off all electric power, hydraulic and pneumatic pressure supplies to the robot!
- Take any necessary measures to ensure that the manipulator does not collapse as parts are
removed, e.g. to secure the lower arm with fixtures if removing motor, axis 2.
Whenever parting/mating motor and gearbox, the gears may be damaged if excessive force
is used!
The motor weighs 27 kg! All lifting equipment used must be dimensioned accordingly!
