Operating instructions
Power connection
Pneumatic
1. Use the hose supplied with the tool.
2. This hose has a valved quick connect coupler which will hold back all air that is in the supply hose.
a. This feature allows the air supply to be safely removed from the tool at any time.
Electric
FAILURE TO PROPERLY SIZE AN EXTENSION
CORD CAN RESULT IN PERSONAL INJURY
AND/OR HARM TO THE ELECTRIC MOTOR
1. For electric tools, be sure to connect the tool
to a properly grounded outlet.
2. If an extension cord is used, make sure the
conductor size is large enough to prevent
excessive voltage drop which will cause loss
of power and possible motor damage. Use
extension cord selection chart.
3. The operating voltage must correspond with
that indicated on identification plate
4. Observe all standard electric shock hazards.
Selection of proper tooling
Clamp rib clamp pad selection
1. Measure inside diameter of tube or pipe. Or using the outside diameter and minimum wall thickness,
calculate the inside diameter.
2. Using the inside diameter and the accompanying clamp rib chart select the proper clamp rib / pad set.
3. Please note clamp pads attach to clamp ribs. Clamp ribs can be used without clamp pads.
Cutting blade selection
1. Measure the wall thickness of the tube or pipe.
2. Select a blade that is wider than the wall thickness.
3. Standard sizes are: 1/2”, 3/4” and 1”. Consult factory for other widths.
4. Cutting blade configuration should be matched to your welding specification.
5. Consult factory for special applications such as: counter boring, seal weld removal, “J” preps, etc.
Installation of proper tooling
Clamp rib installation
1. Remove stop collar (P-13), draw rod nut (P-12) and pull draw rod assembly from mandrel (P-30).
2. Slide clamp ribs over the draw rod (P-11) with the slotted end of the clamp rib towards the actuator (P-
ESCO Tool Company, a Unit of ESCO Technologies, Inc. 9
Holliston, MA - USA | Tel 508.429.4441
14).
3. Insert the clamp rib slots into the slots on the actuator.
4. Inspect springs (P-10A), replace if stretched or damaged.
5. There are two sets of clamp springs per set of clamp ribs.
6. Reassemble, insert draw rod assembly into mandrel and install the draw rod nut and stop collar.
Operating Instructions Revision: PRE-001
Millhog Series - “Prepzilla” Millhog
Cutting blade removal and installation
1. Loosen blade lock screw(s) (P-18), do not remove. If more than one blade lock screw has to be loosened
they should be loosened evenly.
2. Cutting blade must be slid to the outside of the tool post for removal.
3. Insert new cutting blade from the outside of the tool post and align so that the blade fully covers the tube
or pipe wall.
4. Be sure to tighten all blade lock screws
Mounting the tool to the work
1. Using the feed wrench extend the mandrel all the way forward (this moves clamp ribs away from
cutterhead.
2. Retract the mandrel two turns of the feed wrench.
3. Insert the clamp rib portion of the tool into the end of tube or pipe.
4. While positioning the cutting blade away, at least 1/4” from the work, tighten the draw rod nut.
5. Be sure cutterhead can rotate freely, without coming into contact with the tube or pipe, when first
starting tool.
Air connection
1. Use the hose supplied with the tool.
2. This hose has a valved quick connect coupler which will hold back all air that is in the supply hose.
a. This feature allows the air supply to be safely removed from the tool at any time.
2. Connect the air supply.
Operation of tool
1. Engage the throttle lever, this will activate the tool.
2. Using the feed wrench advance the cutting blade towards the work.
3. Use a steady constant feed creating a continuous chip.
a. A constant feed allows the heat generated by the cutting action to be removed by the chip. Heat
build up is a primary failure mode for cutting blade.
b. Engaging a rotating cutting blade with the work surface without feed (rubbing), creates excessive
heat build up.
3. When the desired end prep is accomplished, quickly reverse the feed wrench by reversing the directional
pawl, and retract the cutting blade from the work.
4. Release the throttle lever, this will stop the tool.
5. Disconnect the air supply.
6. Release the clamp nut and remove the tool from the work.
Tool limits
Size limits
1. Minimum inside diameter is 1.575” with standard mandrel.
2. Maximum outside diameter is 8.625”.
3. Maximum wall thickness, 1” with standard tooling.
4. Extremely thin walls may require special tooling to prevent deformation of diameter.

Operating Instructions Revision: PRE-001
Millhog Series - “Prepzilla” Millhog
Material limits
1. Difficult materials may require the following to maximize blade life.
a. Lubrication such cutting oils, soluble oils, soapy water, plain water, etc.
b. Slow the speed of air motor, using a valve on the air supply.
c. Multiple cutting blades to balance the tool.
d. Vary feed rate, often times difficult materials respond to a heavy feed.
Maintenance and servicing
Regular cleaning and lubrication
1. Hose whip, filter and lubricator
a. Inspect filter element by removing nut from end of filter assembly.
b. If the filter is dirty or plugged replace it using filter repair kit
c. Remove filler plug from lubricator and be sure the adjusting screw (AHG-310) is set half way
between open and closed.
d. Fill lubricator, use a light weight air tool motor oil (SAE 10).
2. Gear housing grease.
a. The gear head is a sealed unit. After 500 hours of use it should be internally inspected and re-
greased
b. Use grease NLGI # 2
3. Lubrication for storage
a. Before putting the tool away, fill air inlet with a liberal amount of air tool oil and actuate motor
momentarily. This will distribute oil to internal motor parts, preventing rust build up.
b. Wipe tool down using soft cloth removing all dirt, grease, oil and chips.
c. Lightly coat tool with rust preventive.
User service
1. A qualified air tool technician can provide all service for this machine.
a. Factory service or assistance is always available; contact us at the numbers below.
b. Complete drawings and parts lists are provided in PARTS LI ST AND DRAW INGS section.
NOTE: NO SPECIAL TOOLS ARE REQUIRED TO PERFORM COMPLETE SERVICE.
Servicing by manufacturer or agent
