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.

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.
