Oil change in A1
Description
The following instructions describe the gear oil change for this axis. This description applies to floor-mounted robots. If the robot is installed in an inclined or suspended position, it must be ensured that all the oil can flow out. If necessary, the robot may have to be removed and bolted to the floor.
If the robot is installed in an inverted position, the procedure is to be ap- plied analogously, but with the filler and drain holes reversed.

Material
The following material is required:
| Designation | Article number | Quantity |
| Optigear Synt. ALR 150 | (>>> 12.2 “Aux-iliary and operating materials used” Page 216) | Initial filling quantity: 0.52 l |
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.
Tightening torques
The tightening torques can be found under: (>>> 12.1 “Tightening torques” Page 215)
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.
Preconditions
- The controller is switched off and secured to prevent unauthorized per- sons from switching it on again.
- The gear unit is at operating
- The screw plugs are freely
Work Safety
CAUTION
High oil and surface temperatures after the robot has stopped op- erating
If the oil change is carried out immediately after the robot has stopped operating, the oil temperature and the surface temperature are liable to be high. Touching them may result in burns.
