Not sure what HM 60 is but if it is suitable for use on the splines it will be OK for this as well.
The lube points other than the splines are the center of the conical spring where the clutch pushrod meets it and the narrow front part of the pushrod itself where it goes into the shaft.
Also on the conical spring where it meets the wire ring, the wire ring where it goes into the clutch carrier and the 12 points where the conical spring meets the pressure plate.
The conical spring and the wire ring only need the slighest smear and the same where the conical spring meets the pressure plate but a little more on both places on the clutch pushrod.
