4.4.4 Release the Residual Pressure in 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 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).

Robot Maintenance and Use Area
The maintenance area and use area of the mechanical unit are shown in Figure 4-2. The use
area of the robot can be adjusted according to the user's working environment.

The use area must have the following safety conditions:
A safety fence and safety gate must be installed around the robot. If the safety gate is not
opened, the operator cannot enter the safety fence. An interlock switch, safety latch, etc. are
set on the safety gate. The robot will stop after opening the safety gate;
A safety carpet or photoelectric switch should be installed on the floor so that when the
operator enters the robot's range of motion, an alarm will be issued through the buzzer and
photoelectric switch to stop the robot from moving to ensure the safety of the operator;
The height of the safety fence is not less than 2 meters;
