4.4.3 Lubricant Replacement Steps for J1~J4 Axis Decelerator and
Wrist Parts
1
）
Move the robot to the lubrication position described in Table 4.7.
2
）
Cut off the power.
3
）
Remove the M10*1 hexagon socket screw plugs of the lubricant filling and drain ports, see
Figure 4-1.
4
）
Provide the new lubricant until the new one flows out of the oil drain port.
5
）
Install the hexagon socket screw plug on the lubricant filling and drain port.
6
）
After the oil is supplied, follow the steps in item 4.4.4 to release the residual pressure in the
lubricant chamber.
If the lubrication operation is not performed correctly, the internal pressure of the lubrication
cavity may suddenly increase, which may damage the sealing part, resulting in lubricant leakage
Position Amount Name for the lubricant Remarks
J1 axis decelerator 740cc
MOLYWHITE RE No.00
Rapid oiling will cause the pressure
in the oil tank to rise, the crack of
sealing ring, and the leakage of
lubricating oil. The oil supply speed
should be controlled below 40cc/10
seconds.
J2 axis decelerator 760cc
J3 axis decelerator 350cc
J4 axis decelerator 175cc
