  • Auto-lubrication pump is on the left of the machine. Make sure it is unplugged at the end of use. It is suggested the cable be draped on the front of the machine as a reminder to the next user to plug it in.

  • There are three upper lubrication points. Lubricate the spindle before each use; fill cups to overflowing with medium spindle oil.

Notes

  • When homing the system initially, do NOT walk away; start with the table to right.
  • It is important to make sure the quill is all the way up when changing the tool; the air powered tool changing system can otherwise not reach the bolt. If the quill is not all the way up, the tool changer can also wear the bolt.
  • Adjust the speeds when the machine is running.
  • The direction of the spindle is different for the low and high gear ranges; if the switch is going one way in the low speed range, it will go the opposite in the high gear range.
  • When milling pockets, typically the tool moves clockwise (when viewed from above); the motion of the tool head should also be clockwise in relation to the part.


Lubrication Schedule

Lubricate three headstock oil cups with medium spindle oil before every use.

Lubricate ways with way oil or use automatic power oiler. Remember to unplug the power oiler when done for the day! Otherwise, the automatic oiler will eventually dump a giant puddle of oil under the machine.
