■ Inspecting the J5 axis timing belt
Page 100, "5.3.2 Installing/removing the cover"
, and remove the No. 2 arm cover R.
2) Visually confirm that the symptoms indicated in
Page 106, "(1) Timing belt replacement period"
occurred with the timing belt.
3) Refer to
Page 107, "(2) Timing belt tension measurement"
, and confirm the belt tension.
4) Install the No. 2 arm cover R securely as before and finish inspection.
■ Replacing the J5 axis timing belt
If the timing belt of the J5 axis is removed, the forearm will drop by the self-weight.
(faces in the downward) And, if the positional relation between the timing pulley A <4>
and B <5> deviated, it will become the cause of the position deviation. For the safety
before replacing the timing belt, move the J3 axis so that it may face in the downward
by jog operation.
It is possible for the customer to replace the timing belt, but precise adjustment is
needed to prevent malfunction of the relevant parts. To ask for replacement of the
timing belt, contact the dealer.
