Note: The operation and programming of the FR-1418 requires that the operator have reasonable
proficiency with the features, controls and processes described in Sections 1.0, 3.0, 7.0, and 8.0 (if
applicable) of this manual. Read and understand sections 1.0, 3.0, 7.0, and 8.0 (if applicable) before
proceeding to operate and program the equipment as described in this section.
Note: Consult the references in parentheses after each item for additional information or description
relevant to each topic.
General Warnings:
1.
Keep in mind that the system is designed to melt solder joints on very dense boards. The heaters
are very powerful and can reach internal air temperatures exceeding 450° C (840° F). Surfaces
of the heater, PCB, nozzle, and other components can be VERY HOT. Always use caution to
prevent accidental burns, especially when changing nozzles, unloading boards or components, or
when working around the heater head area.
2.
Never touch any glass optics components with bare hands.
3.
Never wipe any glass optics components with rags or paper towels. Use an optical wipe, camera
lens tissue, eyeglass wipe, or other material which will not scratch the glass.
4.
Never touch the sides (unpolished faces) of the prism. The oil from your hands can penetrate the
bonded seam and adversely affect the image quality.
5.
Never touch the halogen bulbs for the component/board lighting, or the bottom heater quartz
lamps with bare hands. The oils from your skin can cause hot spots on the bulbs/quartz lamps,
resulting in cracking or coating failure.
6.
Maintain good ESD prevention procedures when handling electronic components and boards.
7.
Always disconnect the unit from the electrical and pneumatic supplies before servicing or
maintenance.
