Daily Inspections

Inspect the robot daily to ensure its high performance and early detection of any
abnormalities.
8.2.1

Manipulator

 Visual Inspection
Before turning ON the power to the manipulator, check if any abnormality can be found on the
manipulator. Remove the jacket if it is attached.
 Manipulator Motions and Noise/Vibration during Operation
Check if the manipulator home posture does not change when turning ON the power supply
using the eye mark.
Also, check for abnormal noise and vibration during operation.
Never enter inside the safeguarding and the manipulator working envelope after turning
ON the power supply.
Paint stuck on the manipulator rotating parts prevents them from turning normally and
smoothly. Periodically remove the paint on the manipulator.
A cloth that is soaked in paint thinner can be used for cleaning the inside of the wrist,
because an anti-thinner enclosure is provided. But, be careful not to remove the original
coat of paint on the manipulator.
Tubes and Air Leakage

Check for excessive air leakage from the tubes, the couplings, and the joint fittings of the
motor on each axis when the air is supplied in the manipulator to form the anti-explosion
barrier.
The actual amount of air leakage is not important if a fault in the internal air pressure does not
occur. However, if internal air pressure faults occur frequently, check if the pressure of the air
source and the pressure setting of the pressure reducing valve are correct and if excessive air
is leaking.
