  • Page 10: Tool Set-Up

    VG412 TOOL SET-UP This section has four parts: (1) general set up instructions: (2) set up instructions for short pipes (less than 12 inches): (3) set up instructions for long pipes: and (4) set up instructions for tool installed around the pipe, for example, in the field with a pipe already in position.
  • Page 11 VG412 1. Select location for tool and pipe stand (s). Choose a location that has: a. The required power. Consult the power requirements on page 4. b. The space necessary to adequately handle the pipe to be grooved. c. A level and even surface for tool, pipe stand (s), and footing.
  • Page 12 VG412 2. Set tool upright. Adjust legs to achieve a level tool and assure that all four (4) of the legs are resting on the floor to prevent the tool from rocking, and tighten with a wrench. Figure 4 3. Attach the motor mount to the main frame using four (4) wing handle clamp screws.
  • Page 13 VG412 4. Attach the motor to the top of the motor mount, do not tighten. Rotate chuck to align with hex drive of the pinion and move motor forward to engage. Tighten drive motor chuck with chuck key. Tighten wing handle clamp screws to secure motor in place.
  • Page 14 VG412 6. Adjust the clamp screws, on the lower half of the frame, so that there is an opening at least 1/2” larger than the size of pipe to be grooved. 7. Insert pipe betweem riser blocks and clamp screws.
  • Page 15 VG412 9. Engage one-half (1/2) of gear plate over the track rollers on the bottom half of the frame and rotate upward until the gear half is centered on the pinion gear. Figure 10 10. Engage the other half of the gear plate over the track rollers, and bring the two halves together.
  • Page 16 VG412 12. Select the spacer block for the size of pipe to be grooved. 13. Attach cutoff head assembly on top of spacer block with four (4) allen head screws. NOTE: Retract cutoff blade to clear pipe if necessary by pressing detent lever and turning crank handle clockwise.
  • Page 17 VG412 16. The actuator bar should be set to engage the star wheel with approximately 1/32" clearance at the bottom of the star wheel. Fine adjustment can be made with the two wing screws found in the slots of the actuator mechanism base.
  • Page 18 VG412 SET UP FOR TOOL INSTALLED AROUND PIPE 1. Remove grooving head and cut off head from front of gear plate. Figure 15 2. Separate the two halves of the gear plate by loosening the hex nuts at the joint.
  • Page 19 VG412 4. Select the proper pair of riser blocks from those provided with the tool, and attach to the upper frame with screws provided. The permanently mounted base plates are for the 12” size. Each riser block has the pipe size marked on it.
  • Page 20 VG412 7. Tighten clamp screws on the pipe evenly and with sufficient force to resist rotation of the pipe during cut off and grooving. NOTE: Check the tightness of the clamp screws throughout the cutting and grooving operation, and retighten if necessary 8.
  • Page 21 VG412 10. Engage one-half of the gear plate over the track rollers on the lower half of the frame and roll to engagement with the pinion (pinion gear on the lower half of the frame should be in middle of gear plate half).
  • Page 22 VG412 16. Fine adjustment can be made with the two wing head screws found in the slots of the actuator mechanism base. The actuator bar should be set to engage the star wheel with approximately 1/32" of clearance at the bottom of the star wheel.
  • Page 23 VG412 20. Be aware that while cutting off the end of a pipe, that when the tool bit breaks through the material all the way around, the pipe end will fall down. Also be aware that if you are cutting a long pipe, that both ends need to be supported in a manner that will prevent the pipe and or the tool from tipping or falling in either direction.
  • Page 24 VG412 24. Turn the hand knob until tool bits contact the pipe at the highest point and add 1.5 to 2 turns on the knob for preload. 25. Plug in the power cord and proceed with the groove. The blade will feed automatically, and will stop grooving when it runs out of preload.

  • Page 25: Cutting And Grooving

    VG412 CUTTING AND GROOVING This section has instructions for cutting and grooving various types of materials. This section has three parts: (1) cutting and grooving 6" 8", 10", and 12": gray and ductile pipe of AWWA dimen-sions (2) cutting and grooving gray and ductile 4" pipe of AWWA dimensions: (3) cutting and grooving steel pipe.
  • Page 26 VG412 4. Select the spacer block which corresponds to the size pipe and style of groove, rigid or flexible, and attach to face of gear plate behind cut off head with socket head screws. Figure 28 5. Proceed with cut off.
  • Page 27 VG412 9. Loosen both set screws and install proper groove blade. 10. Adjust the tool bits as shown in Figure 29. Turn hand knob clockwise to expose both set screws "D". Loosen both set screws. Turn adjusting screw "B" to adjust groove depth. Use depth gage to check depth, the lock blade set screws "D".
  • Page 28 VG412 Figure 31 15. As the grooving continues, it will be necessary to stop the gear plate and add more preload at the rate of 1.5 to 2 turns of the hand knob clockwise. When the groove is complete, the depth stops will contact the pipe 360 degrees around the outside, leaving a mark completely around the O.D.
  • Page 29 VG412 16. Stop the gear plate, unplug power drive, release the preload on the blades, and check groove diameter. If groove diameter is not correct, repeat steps 8 to 16.
  • Page 30 VG412 CUTTING AND GROOVING GRAY & DUCTILE 4” PIPE NOTE: When cutting and grooving 4" pipe, additional components must be added to the main frame as well as the gear plate. Also, one grooving head rather than two are used for 4" pipe.
  • Page 31 VG412 1. The 6" block, rigid or flexible, is used with spacer Plate No. 220779. Both of these spacers are installed behind the cutoff head assembly. Figure 34 2. Remove the blade holder assembly from the cutoff assembly by depressing the detent lever and turning crank until holder is completely un-threaded.
  • Page 32 VG412 3. Install 220680 3/8” groove blades into one holder. 4. Attach extender plate No. 220753 to gear plate with two hex head screws. 5. Attach grooving blade holder to extender plate and gear plate using four socket head screws.
  • Page 33 VG412 CUTTING AND GROOVING STEEL PIPE NOTE: The VG412 tool is only recommended for use on steel lined pipe. 1. Instructions are similar to cutting Cast Iron and Ductile Iron Pipe except: Two cutter heads operating simultaneously and using the specified two tool steel cutoff blades, are required for cutting carbon steel pipe.
  • Page 34 VG412 NOTES *Be sure that both blades are sharp to insure good, clean cutting action. These blades are of high quality tool steel and are easily resharpened. DO NOT CUT STEEL WITH CARBIDE TIPPED BLADES. * Be sure that both star wheels are being turned by the acturator bar the same amount each time.

  • Page 35: Disassembly, Cleaning & Storing

    VG412 DISASSEMBLY, CLEANING & STORING The tool should be disassembled and cleaned before moving it to another work site or putting it in storage. The following procedures apply to disassembly and cleaning. 1. Unplug motor from the power source. 2. Slide indexing bar back.
  • Page 36 VG412 • Put the motor and motor mount assembly into a box or other container for transport. Make sure screws are kept with the assembly. 5. Clean gears with a cloth or brush. CAUTION. Sharp cutting and grooving tool blades could cut fingers.

  • Page 37: Maintenance

    This section of the manual provides information about keeping tools in top operating condition. Replacement parts, applicable to these tools, should be ordered from Victaulic to assure proper operation of the tool. All parts are FOB Easton, Pennsylvania, at the price in effect at the time of the order.
  • Page 38 VG412 BLADE SHARPENING Dull blades are the most common cause of cutting difficulties. Dull blades can cause blade failure and damage the blade holders, bearings, and gear teeth. Suggested resharpening schedules are provided in the tables below. The number of cuts possible before sharpening will vary with pipe material, condition, diameter, wall thickness, exterior coating, and interior lining.
