Yamaha Robotics YK120X User Manual

3-16

Always turn off the robot controller and shut off air supply before connecting a
suction hose.

Clean room models have two suction couplers (

φ6) on the rear of the manipulator

base for air suction from the base interior and from the X, Y, R axis joints, and
also have one bellows type suction coupler (

φ3) for the R-axis.

The required degree of cleanliness can be maintained by sucking air through
these suction couplers.
For the suction amount versus degree of cleanliness, see "1-1 Basic specifications"
in chapter 7. For the location of the suction couplers, see "1-2 External view and
dimensions" in chapter 7.

Lay out the suction hoses so as to keep the operator or any other person from
tripping on them. Bodily injury may result if someone trips on the hoses.

Carefully connect the suction hoses to the suction couplers so that they do not
obstruct the movement of the robot manipulator.
