Spindle direction and power feed

The spindle can be driven clockwise or counter- clockwise. The direction of rotation is controlled by the control lever on the left hand side of the drill head. See Fig. 1.

Clockwise or "forward" rotation is the direction of rotation for right-hand tooling -- which is the vast majority of tooling used in machine operations.

However, if you use left-hand tooling for any opera- tions, the spindle direction can be set to counter- clockwise or "reverse."

The power feed direction is determined by the spindle direction. When the spindle is set to its most common direction -- clockwise or forward -- the quill and spindle are driven downward. When the spindle direction is set to counterclockwise or reverse direction, the quill and spindle are driven upward.

Hand feed -- roughing operations

When the feed levers are pushed toward the drill head the power feed mechanism is disengaged. In this position, the feed levers can be used to move the quill and spindle and perform manual drilling or other machining operations.

Fine hand feed using the power feed system

The fine feed control wheel is located on the underside of the right-hand side of the drill head. See Fig. 1. The fine feed control is used as follows:

1.Set the feed rate dial to N -- neutral.

2.Pull the feed levers out so the power feed clutch is engaged.

3.Turn the drill press POWER switch ON and set the control lever so the spindle is turning in the correct direction for the operation you are performing.

4.Turn the fine feed control wheel by hand. The quill and spindle will move downward or upward (depending upon which way you turn the wheel and the direction the spindle is turning) until you stop turning the control wheel.

Power ON and power OFF

If your Model 1230 was connected to its service branch correctly, there will be a service disconnect with an external power cutoff lever or switch which disconnects the drill press from the service branch. This is your ultimate protection against accidental machine start-up when clamping work pieces to the machine and/or inserting or removing tooling. Always be certain you have turned off power at this discon- nect before doing these operations.

Once your workpiece is clamped securely and

the tooling is installed, you can restablish power to the machine by turning the cut-out panel back ON. This will reestablish power to the machine control system and will allow you to use the motor which raises and lowers the arm to position the tooling over the work piece. Raising and lowering of the arm is controlled by the control stick -- see Fig. 3 and read page 7, Raising and lowering the radial arm.

Power ON light

When the cutout box power is ON, the POWER light on the upper left hand side of the drill head (Fig.

1)will be lit. In this mode, power to the coolant pump and to the spindle drive motor is controlled by the switches on the control console.

Flood coolant control

The flood coolant system provided with the drill press is turned on by turning the switch to the ON position. Power OFF to the coolant pump is achieved by turning the switch counterclockwise to its OFF position. (If coolant does not flow, check the pump rotation by observing the pump shaft. It should be rotating in the direction of the arrow on the pump casting. If it is not rotating in the correct direction, see Electrical, for more information.)

Spindle motor controls

The power to the spindle motor controlled as follows:

1.The cutout box control lever must be in the ON position so power is being fed to the drill press.

2.The two speed spindle drive motor switch must be in either HI or LOW position.

3.The control ON/OFF switch must be pushed ON.

4.The arm/spindle control lever must be pulled forward (clockwise rotation) or backward (counter- clockwise rotation.) See Using the control lever, page 11.

Turning spindle drive motor power OFF

To turn power OFF on the spindle drive motor do one of the following:

1.Put the two speed motor switch in OFF position, OR...

2.Push the Control ON/OFF switch off, OR...

3.Put the arm/spindle control lever in its middle (neutral) position, OR...

4.Push the large, red emergency off STOP switch, OR...

5.When servicing the tooling or other machine components, put the service disconnect lever in OFF position.

Once the STOP switch has been pushed (4., above) none of the other switches on the panel can be used to control power to the spindle drive motor or coolant pump until the STOP switch has been re-set.
