3. Three-month inspection
This section describes the maintenance work performed once every 3 months.
3.1 Head unit
3.1.1 Cleaning and replacing the air filter
As a general guideline, the filter should be inspected once every 3 months, although this may vary somewhat
depending on the air supply conditions and the operating time. If lightly soiled, the filter can be clean by using
the air blow tool. The filter should be replaced when it can no longer be adequately cleaned by air-blowing.

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.
