5.3.6 How to lubricate the spring shaft area
This robot uses springs for gravity compensation for the J2 axis drive system. The small power consumption of
the motor is achieved by connecting spring hooks to the spring shafts set in the J2 axis motor area and J

case, thereby compensating for the gravity by the spring force. Depending on the conditions under which the robot
is used, wear may occur due to lack of lubrication in the spring shaft areas. If wear is detected during periodical
inspections, it is necessary to apply grease to the two areas shown in
. Use highly viscous grease (water-
soluble types are not allowed).
