The purpose of the functional inspection is to ensure that screws, bolts, tools and robot arm are
not loose. The screws/bolts mentioned in the inspection plan should be checked with a torque
wrench with the correct torque, specified in 4.1.4 Torque values.
For the robot arm mounting bolts, these specifications can be found in the User Manual under the
Mounting section.

3.1.4 Cleaning

You can wipe away any dust/dirt/oil observed on the Robot Arm using a cloth and one of the
following cleaning agents: Water, Isopropyl alcohol, 10% Ethanol alcohol or 10% Naphtha. In rare
cases, very small amounts of grease can be visible from the joint. This does not affect the
function, use, or lifetime of the joint.
