3 Maintenance3.2.2. Maintenance schedule873HAC023637-001 Revision: B3.2.2. Maintenance scheduleGeneralThe robot must be maintained regularly to ensure proper function. The maintenance activitiesand intervals are specified in the table below.Non-predictable situations also give rise to inspections of the robot. Any damages must beattended to immediately!The inspection intervals do not specify the life of each component.Maintenance scheduleThe table below specifies the required maintenance activities and intervals:1. A regular interval implies that the activity is to be performed regularly, but the actualinterval may not be specified by the robot manufacturer. The interval depends on theoperation cycle of the robot, its working environment and movement pattern.Generally, the more contaminated environment, the closer the intervals. The moredemanding movement pattern (sharper bending cable harness), the closer the intervals.2. The battery is used as a back-up when the robot system is switched off. Therefore, thelife of a lithium battery depends on how frequently the power to the system is switchedoff and also if the environment temperature is higher than recommended operatingtemperature. The life varies from 12 - 36 mths, depending on current conditions. Analert is given on the TPU or the FlexPendant when the battery is nearly discharged andit must then be replaced within a month.Maintenanceactivity Equipment Interval Detailed in sectionChange Gearbox oil, axes 5 and 6 20,000 hrs Oil change, gearbox axes 5and 6 on page 92.Change Battery, measurementsystem12 - 36 mths 2) Replacement ofmeasurement systembattery pack on page 95.Cleaning Complete robot Regular 1) Cleaning, complete robot onpage 97.
