12 Repair
Information!
This description applies analogously to all of the industrial robots listed in Chapter 1,
regardless of the variant or model shown in the illustrations.
12.1 General
Information!
Observe Chapter 5, “Safety”!
Important repair operations for assemblies to be repaired are described in the sections. This
work comprises the removal and installation of assemblies. The user’ s personnel may not
carry out dismantling work going beyond the scope of these operations unless they have
been trained by KUKA for that particular purpose and have the necessary measuring and
testing equipment at their disposal as well as the appropriate documentation.
The description of the repair work is based on the assumption that the work is carried out
by skilled and appropriately trained personnel. Deviations from the specified removal and
dismantling procedures are permitted, provided they are not of a fundamental nature and
endanger neither equipment nor persons. No particular reference is made to safety regula-
tions or trade association regulations; these are always to be observed and are supple-
mented in this manual where necessary by remarks introduced by a warning triangle or a
hand symbol.
Warning!
When any work is being carried out in the manipulator’s danger area, the robot
must be switched off and the main switch secured with a padlock to prevent
unauthorized persons from starting it up again. If this is not possible in the
opinion of the user, it must be ensured that an EMERGENCY STOP pushbutton
can be immediately actuated at all times.
When assemblies are removed or work is carried out on an installed
manipulator, it must be ensured that the manipulator is not able to move on its
own.
Information!
The description of the repair work only covers those operations that do not necessitate
subsequent calibration of the manipulator.
Notice!
The screw sizes and strength classes (standard strength class 8.8) specified in
the sections for assemblies to be repaired are valid at the copy deadline. The
specifications contained in the Parts Catalog are, however, always to be taken as
the most up--to--date information.
Screws of grade 10.9 and higher may only be tightened once with the rated tightening torque.
When the screws are next slackened they must be replaced with new ones.
The description of the repair operations is subdivided into job steps with numbers in brackets
appearing before them. The text which immediately follows these steps must also be read
if it is specially marked by a warning triangle or either of the hand symbols. Many of these
marked texts refer to the preceding job
step.
