3.2 PU-axis
The PU (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 our sales representative for assistance. Disassembly and cleaning of
the PU-axis by the user will void the warranty.

3.3 Base
This machine is equipped with the air intake fan filters (2 in total: 1 each for left and right on the front of the
machine) to prevent the heat generated while moving axes.
If the filters are not cleaned properly, the temperature inside the machine may rise due to filter clogging. Clean
the filters to prevent lowering of the machine function or shortening of the service life. As the filter is cleaned
after detaching the fan unit, power off the machine when cleaning the filter.
