Required equipment
Do's and don'ts!
The section below specifies some special considerations when cleaning the robot.
Always!
• Always use cleaning equipment as specified above! Any other cleaning equipment
may shorten the life of paintwork, rust inhibitors, signs, or labels!
• Always check that all protective covers are fitted to the robot before cleaning!
Never!
• Never point the water jet at bearing seals, contacts, and other seals!
• Never spray from a distance closer than 0.4 m!
• Never remove any covers or other protective devices before cleaning the robot!
• Never use any cleaning agents, e.g. compressed air or solvents, other than those
specified above!
• Never spray with a high pressure cleaner onto the sealing cup at the bottom of the
motor 6 spiral cable (item A in the figure Special points)!
• Although the robot is watertight, avoid spraying connectors and similar items with a
high pressure cleaner!
Foundry versions
In working environments, e.g. foundries, where the robot may be exposed to fluids that dry
to make a crusty surface, e.g. release agents, clean the cable harnesses to prevent the crust
damaging the cables:
• Clean the spiral wound cables to motor 6 (item A in the figure Special points on page
212) with water and a cloth!
• Clean the remaining sections of the cable harnesses as detailed above!
