Product manual - IRB 8700

3HAC052853-001 Revision: M

Release the brakes on axis-2 to allow the lower

arm to position according to the lifting force ap-

plied from the overhead crane. This eliminates

any strain in the upper arm shafts.

Remove the brake release from R2.MP2.

Put a piece of wood (or similar) between

parallel arm and parallel rod, used as pro-

tection to prevent the rod from moving un-

expectedly during the continued procedure.

Remove the attachment screw with washer

that secure the rod shaft.

Remove the protection plugs (4 + 4 pcs)

and fit 2 + 2 M10x80 screws in the holes.

Adjust the screws against the parallel rod

from both sides.

Keep the protection plugs. They shall be

refitted when the work is done.

wings from pinching when pressing the

shaft and thereby making it more difficult

to press the shaft in or out.
