1.4 Cleaning the Y-axis linear scale
If the Y-axis linear scale (scale tape) is dirty, an error may occur when reading the linear scale. To prevent such
an error, the linear scale must be cleaned periodically.

Periodic maintenance items
2.2 Inspecting each axis (monthly)
Inspect the ball screws on the X, W, U, and PU axes and the linear guides on the X, Y, W, and U axes. The
checkpoints are listed below.
n
NOTE
A grease spattering prevention cover is attached to the X-axis. Before starting the inspection work, detach this grease
spattering prevention cover while referring “Detaching grease spattering prevention cover” described later on.
Checkpoints
1. Any foreign matter adhering to the ball screws and linear guides?
Check if any fallen chips have adhered to the X and Y axis ball screws and/or X, Y and W axis 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.
e
3. Any abnormal sounds from the ball screws?
Press the emergency stop button. Then check for any abnormal sounds while pressing the X-axis by hand.
Countermeasures
1. Ball screws and linear guides may be damaged when chips and other material bite into them. If chips are adhering,
wipe them off along with the grease or remove with tweezers, etc.
2. Apply grease while referring “Cleaning and lubrication” described later on.
3. Consult your YAMAHA sales office or representative when abnormal sounds occur even after trying the
countermeasures in the above steps 1 and 2.
