Attention
To tighten and replace the screws, you must use a torque wrench to tighten with the
correct torque, and then paint to fix it. In addition, it should be noted that bolts that are
not loose should not be tightened with a torque higher than the required torque. For
screw tightening torques, refer to “Appendix A Screw Tightening Torque Table”.
4.3 Inspection of Lubricant
Inspect the iron powder concentration in the lubricant every 5000 hours or every 1 year (For
stamping purposes, every 2500 hours or every six months). Replace the lubricant or decelerator if
the concentration exceeds the standard value. Please contact the service department when in need.
Tools needed as follow:
Number Specifications Remarks
1 OM-810 iron powder concentration meter Manufactured by Idemitsu Kosan
2 Filling gun
The nozzle diameter should be less than 17mm and
should be equipped with a counting device.
3 Sealing tapes /
Attention
In inspection, please supply with the filling gun if a certain amount of lubricant
has flowed out of the robot. The nozzle diameter should be less than
Φ
17 mm.
The lubricant supplied should not exceed the designated amount limit.
Attention
After inspection or refilling, please seal the pipe connection with sealing tapes.
The filling gun equipped with a counting device is recommended. Please check
the lubricant amount changes after refilling to ensure that it is within the
designated amount limit.
Attention
The inner pressure of the decelerator rises dramatically right after the
robot is stopped and the lubricant might squirt out once the
inspection screw is untightened. Lubricant should be refilled when the
air pressure of the decelerator is gradually released.
Attention
The lubricant should be constantly inspected to ensure its working
proficiency.
