Inspecting, cleaning and greasing the PU (push-up) shaft (option)
The push-up shaft 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 push-up shaft 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 push-up shaft to ensure it
operates correctly.
c
cleaning of the push-up shaft by the user will void the warranty.

Required tools
• Hex wrench (3mm)
