CHANGE THE MILLING UNIT HOLDER
Each milling unit holder corresponds to a fixed bevel angle. In order to change the bevel angle, the
operator must change the milling unit holder. Follow the steps below to change the milling unit
holder.
1. Unplug the milling unit from the carriage.
2. Remove the milling unit holder from the carriage by loosening interlock screws (1.4)
and sliding out the holder.
3. Loosen the bevel depth interlock (3.2).
4. On the milling unit, rotate drive ring (2.3) clockwise, to the outermost milling head position.
5. Remove the milling unit holder from the milling unit.
6. Install desired milling unit holder on milling unit, aligning the bevel depth interlock with the
slot on the milling head casing (2.2).
7. Set bevel depth, then block the movement between the holder and milling unit by tightening
the bevel depth interlock; it prevents bevel depth change during milling.
8. Secure the milling unit holder, along with mounted milling unit, onto the carriage using
milling unit interlock. Slide the holder in to place and secure the interlock screws.
OPERATION
Step-by-step operation of the Pitbull is described below. Please refer to the “Remarks” section of
this manual for additional operating tips.
1. Install the rail and milling unit as described in “Set-Up.”
2. Plug the carriage in to appropriate 230V power supply with protection circuit.
3. Switch the main switch (1.5) to ON. The Pitbull is now ready to operate.
4. Adjust the carriage speed potentiometer (1.8) to a minimum.
5. Switch the carriage direction switch (1.7) to the required direction of milling.
6. With the milling head not contacting the work piece, start the main motor using the green
“I” button on the milling unit switch (1.6).
7. Adjust bevel depth, if needed.
A. Loosen up bevel depth interlock (3.2) using knob.
B. Rotate drive ring (2.3), using lever (2.4), to move the milling head closer to the work
piece.
C. Clamp interlock again.
8. Increase speed slightly to gently start milling.
9. Adjust speed in order to optimize the machining process. Set the speed such that the
overload indicator on the milling unit switch does not flash.
Note: Short term operation with overload indicator flashing is permissible as described in the
“Remarks” section of this manual.
10. Carriage movement automatically stops upon running into end clamp (4.3) or any other
obstacle.
11. Adjust bevel depth for the next pass. (Follow A-C of step 7)
12. Start milling in the opposite direction using direction switch.
13. Apply this method until required bevel has been obtained.
14. Stop the milling unit by pressing the red “O” button on the milling unit switch.
