When the bolts need tightening and replacing, a torque wrench must be used to properly
tighten, and then fix the bolts by paint coating. Besides, unloosened bolts are forbidden
to be tightened with torque that higher than required.
4.3 Change lubricant
The robot needs to replace the lubricant every 11,000 hours or every 3 years (taking the
shorter interval between the both).The information or process that the capacity of lubricant
required for each axis, the azimuth of each axis when filling the lubricant, the steps of
replacing the lubricant, are refer to the contents of this section. If you have any questions, or
need technical support, please contact our after-sales service department timely.

Rapid injection will cause pressure rising in
the lubricant tank, and then the lubricant will
leak due to cracking of sealing ring.
Therefore, injection speed should be
controlled lower than 40cc/10 seconds.
