2.3.7 Greasing of Reduction Gears (TH250A, TH350A, TH350A-T)

To lubricate the reduction gears, use the following grease.
• Harmonic grease 4B No.2 (Maker: Harmonic Drive Systems)
• DO NOT mistake the type of grease. Otherwise, the robot performance may
deteriorate or the robot may malfunction.
Remove the axis 1 cover and arm 2 cover, and fill the specified volume of grease
from the grease nipples, using a grease gun.
The greasing volume is 5 cm
and 2.13.
(For dismantling the arm 2 cover, see Para. 2.3.9.)
The type of grease nipple is A–M6F.
As the axis 4 reduction gear of TH250A, TH350A and TH350A-T and axes 1, 2, 4
reduction gears of TH180 are grease-sealed, they need not be greased at all.
