4.3.4 Release the Residual Pressure in the Lubricating Oil Cavity
After the oil is supplied, in order to release the residual pressure in the lubrication tank, the robot
should be properly operated. At this time, install a recovery bag under the lubricant inlet and outlet to avoid
the spilled lubricating oil from scattering.
In order to release the residual pressure, when the oil drain port is opened, the J1 axis is in the range of
± 30 °, the J2 / J3 axis is in the range of ± 5 °, the J4 axis and J6 axis are in the range of 30 ° for more than
20 minutes, and the speed is controlled in the low-speed movement state.
When the above actions cannot be performed due to the surrounding conditions, the robot should be
operated for the same number of times (if the axis angle can only be half, the robot should be operated for
twice the original time). After the above actions are completed, install the sealing screw plug on the oil
drain port (use a combination pad or wrap a sealing tape).

Timing Belt Maintenance
The J5 and J6 axes of the robot are driven by timing belt, which may become loose after running for a
period of time, resulting in the decline of the accuracy of the robot. At the same time, after a long time of
operation, the timing belt may be worn, cracked, etc. If it is not replaced and maintained, it may cause
transmission failure and even economic loss.Therefore, it is necessary to check the running status of the
timing belt regularly (recommended every six months). If it is loose, it should be tensioned in time. If it is
damaged, it should be replaced in time to ensure the transmission accuracy and stability of the timing belt.
4.4.1 Timing Belt Tension
A tension gauge is required for timing belt tensioning. Customers can operate it by themselves or
contact our company's after-sales service personnel.
The standard range of the tension force of the J5 axis timing belt of the ER10-1600 robot is 87±5HZ,
and the standard range of the tension force of the J6 axis timing belt is 130±5HZ. Refer to the standard for
testing and adjustment.The specific operation procedures are as follows:
（
1
）
Remove the cover plate of the robot wrist part, and use the timing belt tension gauge to detect the
tension of the J5 and J6 axis timing belts. If the tension is within the standard range, there is no need to
tension and the maintenance ends. If the tension deviates from the standard range, proceed as follows
（
2
）
Loosen the fixing screw of the motor mounting plate until the position can be adjusted left and
right.
（
3
）
Adjust the tension of the timing belt through the adjusting screw of the motor mounting plate, and
use a tension gauge to detect the tension until it meets the standard range.
（
4
）
Tighten the fixing screws of the motor mounting plate, and refer to the appendix standard for
torque specifications.
（
5
）
Properly loosen the adjusting screw, and then tighten the lock nut on the adjusting screw to
prevent the screw from loosening.
（
6
）
Install the cover of the wrist body part, and the maintenance is over.
