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