AND INSPECTION
OCTOBER 2005
1. At the initial running, confirm the following before turning power on.
a. Inspect for and remove any article other than material (chip, etc.) to be trans-
ported on conveyor link belt portion.
WARNING!
Make sure hands, feet and clothing are clear of all moving parts.
2. Confirm the direction of rotation by turning switch on for about two seconds.
a. If motor rotates in reverse, correct electrical connection.
3. Run conveyor continuously while machine tool is exhausting chips.
On US machines, hitting the VMC Emergency Stop will stop all machine operations
including the chip conveyor.
On CE machines, hitting the VMC Emergency Stop, opening the front door, or switching
off an Estop switch at the conveyor chute will stop the chip conveyor.
NOTE
The Estop switch at the chute stops only the conveyor; it has no effect on the VMC.
When the chip conveyor is stopped, it must be restarted at the chip conveyor control by
switching it off, and then on again. Closing the front doors on a CE machine or resetting
the Estop switch will not restart the chip conveyor.
1. Maintain oil level in the speed reducer at specified level; check at least once a year.
2. Keep correct tension of conveyor chain by adjusting take-up bearing. (Obtain equal
tension on both right and left hand conveyor chains by adjusting screw.)
