7.2.1        Greasing Screw Rod of Z-axis

If the grease on the screw rod has been used up, the screw rod may be worn down and make a noise. You need to check the grease every other year. If the grease is applied too much or uneven, the load of motor may be increased and the grease may be dripped from the screw rod. You can check whether the grease is used up by wiping the surface of the screw rod with air-laid paper. If there is no grease on the air-laid paper, the grease is used up.
