⑥ While holding the head cover base by hand, open it slowly. (The cover can be opened at a certain

angle due to the left-side wire.)

⑦ Apply grease to the R-axis gear (3 points), R-axis spline shaft’s upper section and Z-axis ball screw’s

upper section of each head. Do not apply an excessive amount of grease as doing so may cause grease

splash. (An appropriate amount that forms a film of oil on the gear surface is sufficient.)

⑧ To spread the grease over the entire moving area, move the R- and Z-axis by hand. For the R-axis, the

heads having even or odd numbers must be rotated at lease one turn. For the Z-axis, each head must be

moved up and down a few times.

⑨ Install the head cover base in the reverse order of removal.

⑩ Raise all the heads approximately to the height of the machine origin by hand.

⑪ Attach the head cover unit.
