The following maintenance schedules give an overview of regular cleaning and parts
replacement procedures.

The stated intervals are indicative and depend on the operating environment
and frequency of usage of the robot.

NOTICE

Only use approved spare parts.
Mobile Industrial Robots disclaims any and all liability if unapproved spare
parts are used. Mobile Industrial Robots can not be held responsible for any
damages caused to the robot, accessories or any other equipment due to use
of unapproved spare parts.

8.1 Regular weekly checks and maintenance tasks
