n If the robot is utilized in adverse condition(such as spot welding, grinding, etc.), perform the inspection more frequently to ensure proper reliability of the robot system

n Inspect all visible cabling, and replace them if damaged.

n Check the mechanical bumper devices for deformation and damage. If the bumper or Dog is bent, replace it immediately.

n Check the tightening torque of main bolts as shown in [Figure 4.1].

n Check the abnormal noise in an automatic or teaching mode in order to ensure the condition of power transmission (such as motor, reducer, etc).

n Check the gas spring regularly to keep the good pressure and supplement it if necessary.
