Action
Move axes 3 and 5 to a horizontal position, and
make sure that the oil plug, filling and inspection
is facing upwards.
DANGER
Turn off all:
•
electric power supply to the robot
•
hydraulic pressure supply to the robot
•
air pressure supply to the robot
Before entering the robot working area.
Make sure that the oil temperature is +25°C
±10°C.
Remove the oil plug, filling and inspection.
Slowly turn axis 4 until the axis-4 angle reads
+72.5° to +77.5°.
Inspect the oil level in the hole for the oil plug,
filling and inspection.
The oil should reach all the way up to the extern-
al edge of the thread for the oil plug, filling and
inspection.
Note
If needed, use a clean, narrow object, for ex-
ample an oil stick or a cable tie, to gently poke
the oil surface. This will avoid surface tension
from stopping air to enter into the gearbox.
Adjust the oil level, if required.
Refit the oil plug.
