3.2 Cleaning and greasing the push-up axis (PU-axis)
The push-up axis is designed to prevent flexing or warping of the board during clamping and is important
because it prevents depressing of the board during component mounting.
The PU axis also prevents deviations in the component mounting accuracy due to the board depressing during
component mounting, so it is important to regularly clean and inspect the PU axis to ensure it operates
correctly.
c
CAUTION
If trouble occurs with the PU axis, then contact YAMAHA sales representative. Disassembly and cleaning of the PU axis
by the user will void the warranty.
