Everyday cleaning
You can wipe away any dust/dirt/oil observed on the robot arm and/or Teach Pendant using a
cloth and one of the following cleaning agents: Water, Isopropyl alcohol, 10% Ethanol alcohol or

not affect the function, use, or lifetime of the joint.

isopropyl alcohol (rubbing alcohol).
1. Wipe the robot with a hard twisted micro fiber cloth and 70% isopropyl alcohol (rubbing
alcohol).
2. Let the 70% isopropyl alcohol dwell on the robot for 5 minutes, and then clean the robot
using standard cleaning procedure.
