2.6 Robot in hot environments
2.6.1 Start of robot in hot environments
Introduction
This procedure describes how to start the robot in a hot environment. This
procedure must be performed the first time the robot is started in a hot environment
or if it has not been used for some time in a hot environment.
There is a possibility that some overpressure has been built up in the system. This
overpressure must be released before starting up the robot.
Releasing overpressure in gearboxes
Use this procedure before the start of the robot in a hot environment to release
potential overpressure being built up in gearboxes.
Note Action
DANGER
Turn off all:
• electric power supply
• hydraulic pressure supply
• air pressure supply
to the robot, before entering the robot work-
ing area.

Note
Open the oil plug just enough for the overpres-
sure to be released.
