11. Check the oil level. If it is low, add oil. Use MOBIL SHC-630 synthetic gear oil (Viscosity Grade
ISO 220). For the HRT210SHS use Mobil SHC-626 synthetic gear oil (Viscosity Grade ISO 68).
12. Save the packing materials in case you need to ship the unit.
13. At the end of the workday or shift, it is important to clean the rotary table. The table should be free
of any chips or grime. Clean with a chip brush and apply a coat of a rust preventative.
CAUTION! Do not use air gun around front or rear seals. Chips may damage seal if
blown in with an airgun.
14. Turn on the mill (and servo control, if applicable) and home the table by pressing the Zero Return
button. All Haas indexers home in the clockwise direction as viewed from the platter. If the tables
home counter-clockwise, press E-stop and call the Haas service department.

QUIPMENT
Interfacing is an unfriendly word that inspires fear in most non-electrical people. In reality, you are interfacing
objects all the time. Hooking up a stereo, computer, or VCR requires many connections, or interfaces. Plug-
ging a lamp into the wall and turning the switch on is really interfacing a 100 watt incandescent lamp up to a 15
Megawatt generating plant. While there are hundreds of connections between your lamp and the power com-
pany, it is really a simple process. The HAAS control is just as simple.
The HAAS control has two signals: one input and one output. Your equipment tells the HAAS control to index
(an input), it indexes, and then sends a signal back to your equipment that the index (an output) has been
completed. These signals are simply switch closures, or in mechanical terms, relays. A switch (relay) is closed
inside your machine that tells us to index, we index and then close a switch (relay) inside our control to tell
your machine that we are done. This inferface requires four wires; two for each signal. They are from the remote
input on the back of the HAAS control and from your equipment or CNC ( C omputer N umerically C ontrolled)
machine.

There are two connectors used for the RS-232 interface. They are both DB-25 connectors, one male and one
female. Multiple controllers are connected by daisy-chaining the boxes. The cable from the computer connects
to the female connector. Another cable can connect the first box to the second by connecting the male connec-
tor of the first box to the female connector of the second. This can be repeated for up to nine controllers.
