Designation Article number Quantity
Optigear Synt. ALR 150 (>>> 12.2 "Aux-
iliary and oper-
ating materials

Page 336)
Initial fill-
ing quan-
tity: 0.23 l
Tightening torques
The tightening torques can be found under: (>>> 12.1 "Tightening
torques" Page 335)
These are valid for screws and nuts where no other specifications are giv-
en.
Screws of strength class 10.9 and higher as well as screws with test cer-
tification may only be tightened once with the rated tightening torque.
When the screws are first slackened they must be replaced with new
ones.
Refilling quantity
CAUTION
The quantity of oil drained depends on the draining time and the oil
temperature. The refilling quantity is the quantity of oil that was drained
from the gear unit at the correct operating temperature and with the cor-
rect draining time. This oil quantity must be determined. Only this quan-
tity of oil may be used when refilling.
If less than 70 % of the specified oil quantity flows out, flush the gear
unit with the determined quantity of drained oil once, then pour in the
amount of oil that was drained. If less than 50% of the specified oil
quantity flows out (e.g. inclined installation), the flushing operation must
be repeated twice. During the flushing procedure, move the axis at jog
velocity throughout the entire axis range.
The oil quantities specified in the table correspond to the oil quantities
in the gear unit at first filling.
Precondition
• The gear unit is at operating temperature.
• The arm and in-line wrist are in horizontal position.
