1. If the robot is run at ambient temperatures higher than 50°C, it may require
maintenance more frequently.
2. Replace when damage is detected or when approaching the life limit, specified in
Expected component life on page
3. The battery is used as a back-up when the robot system is switched off. Therefore, the
life of a lithium battery depends on how frequently the power to the system is switched
off and also if the environment temperature is higher than recommended operating
temperature. The life varies from 12 - 36 mths, depending on current conditions. An
alert is given on the TPU or the FlexPendant when the battery is nearly discharged and
it must then be replaced within a month.
4. The interval is the same as with the interval for changing axis 2 gear oil, because the
type and degree of operation is similar.
