2. Monthly inspection
This section mainly explains the cleaning and lubrication procedures after inspection.
Inspect the ball screws and the guides on the X and Y axes. Checkpoints are listed below.
A grease spattering prevention cover is installed to the X and Y axes. Remove these covers when inspecting
the ball screw and guide.
n
Checkpoints
1. Any foreign matter adhering to the ball screws and linear guides?
2. Do the ball screws and linear guides have the correct amount of grease?
Check if grease has flowed off or splattered in the air failing to adhere. Also check if grease has discolored or
hardened.
3. Any abnormal sounds from the ball screws?
Press the emergency stop button. Then check for any abnormal sounds while pressing the head assembly or conveyor
table by hand along the X-axis or Y-axis back and forth.
n
Countermeasures
1. Ball screws and guides may be damaged when chips or debris bite into them. If chips or debris are adhering, wipe
them off along with the grease or remove with tweezers, etc.
2. Apply grease while referring to the "Cleaning and greasing" instructions described later.
3. Consult your YAMAHA sales office or representative when abnormal sounds occur even after trying the
countermeasures in the above steps 1 and 2.
c
CAUTION
When using grease, read and follow "Precautions when handling grease" described in "2. Preparing for maintenance
tasks" in Chapter 1.
c
CAUTION
If abnormal noise is emitted from the X or Y axis ball screw or guide, then contact our sales representative for
assistance. Disassembly and cleaning of the ball screw or guide by the user will void the warranty.
