Check Spindle Chiller Level and Settings
The spindle on this machine is equipped with an oil chiller unit. This oil chiller acts as a reservoir and a
temperature regulator for the spindle. Once per month the chiller should be checked for proper settings
and oil levels.
To check the temperature settings, first press the ON/
OFF button until the “ROOM” LED is illuminated. This
will display he room temperature in Celsius. Next, hold
either of the ‘up/down’ buttons until the numbers on the
display flash. They will display a number between 15 and
-15. This number indicates the target oil temperature in
comparison to the room temperature. For best results this
number should display 3.0 in a room that has an average
temperature of 19.5 degrees(C) or lower, or -3.0 in a room
that has an average temperature of 20 degrees(C) or
higher. Press the “ON/OFF” button to save any changes.
The oil level sight glass is located on the bottom of the
oil cooler. This also has a mercury thermometer in it to
indicate oil temperature. This sight glass should be filled
to the black line at the top. If he oil is not filled to the black
line it must be topped off with air tool oil. The oil fill can
be reached by removing the air filter and two phillips head
screws located above the panel labeled “SUPPLY.”
