Maintenance Plan

Overview

The maintenance intervals may have to be adapted to the greatly varying operational hours depending on the application.

For procedures to replace the different parts, refer to Replacing Parts.

Maintenance Schedule

Intervals	Action
Every 150 hours of operation or weekly	Verify the robot by visual inspection for any damage or missing parts, especially for moving parts and parts at risk for collisions such as grippers, upper arms, lower arms, springs, telescopic axis, or parallel plates. Replace the arms if these are bent or dented. Clean the robot mechanics.
Every 300 hours of operation or every two weeks	Verify the slide films, ball sockets, universal joints, and rolls for wear and replace them if necessary. Only for an optionally mounted VRKPXYYYYY00038, VRKPXYYYYY00039, VRKPXYYYYY00041, VRKPXYYYYY00045, VRKPXYYYYY00046, VRKPXYYYYY00049, VRKPXYYYYY00050, VRKPXYYYYY00052, or VRKPXYYYYY00053: Verify the cables for wear and replace them if these are damaged or worn out
Every 1,000 hours of operation or every three months	Verify all moving parts for bolted connections. Verify the output shaft sealing of gearboxes for deposits of dirt and clean. Verify the sealing gaskets at maintenance covers, media covers and motor covers by visual inspection for any damage and replace them if necessary.
Every 2,000 hours of operation	Replace the springs and spring rolls of the lower arms. Replace the ball sockets. Replace the slide films of the telescopic axis. Verify the universal joints on the telescopic axis and replace them if these are appreciably worn.
Every 5,000 hours of operation	Verify the ball pins and replace them if necessary.
Annually	Verify the brake function during operation.
Every 20,000 hours of operation	Replace the main gearboxes and motors. Replace the four-axis parallel plate (with rotational axis bearing). Only for VRKP2•••WD / VRKP4•••WD / VRKP4•••NO / VRKP4•••CW / VRKP4•••WF / VRKP5•••WF / VRKP6•••WF robot: Verify the fans for operation and replace them if necessary. When using an optionally mounted VRKPXYYYYY00038, VRKPXYYYYY00039, VRKPXYYYYY00041, VRKPXYYYYY00045, VRKPXYYYYY00046, VRKPXYYYYY00049, VRKPXYYYYY00050, VRKPXYYYYY00052, or VRKPXYYYYY00053: Replace the module.
Every 40,000 hours of operation	Replace the gearboxes and motors of the rotational axis. Replace the upper arms.
Every 1,000 emergency stop situations	Replace the upper arms.
Each removal of the covers	Replace the sealing gasket of any cover you remove.

NOTE:

The gearbox has been lubricated for life.
Do not lubricate the ball sockets.
