Inspecting oil level, axis-1 gearbox (suspended robot)
Use this procedure to inspect the oil level in the axis-1 gearbox, when the robot is
suspended.
This procedure is only valid for Other design than Type C and Type D .
Note
If the suspended robot is design Type C and Type D , the oil level can not be
inspected while the robot is hanging upside down. To make sure that the correct
amount of oil is refilled after some repair work, make a note of how much oil was
drained and make sure to refill with the same amount. If in doubt, the suspended
robot must be dismantled from its suspended position, secured in a floor mounted
position, and then the oil level can be inspected according to
Inspecting the
gearbox oil level in a floor mounted robot on page 111 .
Note
If the suspended robot is Other design than Type C and Type D , and the axis-1
gearbox is filled with an amount of oil suited for an inverted position, the oil level
can only be inspected in the inverted position! If the robot was taken down to
stand on the floor, the oil level would be above the oil plug hole, which would
result in oil leakage if the plug would be opened while robot stands on the floor!
Note Action
WARNING
Handling gearbox oil involves several safety
risks, see
Gearbox lubricants (oil or grease)
on page 36 .

DANGER
Turn off all:
• electric power supply
• hydraulic pressure supply
• air pressure supply
to the robot, before entering the robot
working area.
2
CAUTION
The gearbox can contain an excess of
pressure that can be hazardous. Open the
oil plug carefully in order to let out the ex-
cess pressure.
