2. Do not modify or defeat safety devices
3. Cutting blades are sharp and can cause serious injury, use caution when handling tool when blades are
installed
4. Chips can be hot and sharp. Be careful when clearing from tool.
5. Moving and stationary parts can pinch or cause serious injury. Pay extra attention to rotating cutting
blades as they can not be adequately guarded.

Clamp ribs / pads
Secures tool to tube or pipe inside diameter.
Come in sets of three
Available in many sizes, see accompanying
clamp rib chart.
Mandrel

connecting air supply.
Always disconnect air supply before installing,
changing or securing cutting blades, adjusting,
moving, or breaking down.
Air motor
Provides power to gear head.
Gear head
Rotates cutterhead.
Axially moves on mandrel.
Selection of proper tooling
Clamp rib 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(s).
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, compound bevels , “J” preps, etc.

Millhog Series 314 “Commander”
Installation of proper tooling
Clamp rib installation
1. Remove draw rod nut (C-15), and pull draw rod assembly from mandrel (C-37).
2. Slide clamp ribs over the draw rod (C-14) with the slotted end of the clamp rib towards the actuator (C-
11).
3. Insert the clamp rib slots into the slots on the actuator (C-11).
4. Inspect springs, 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.
Cutting blade removal and installation
1. Loosen blade lock screw(s) (C-53), do not remove. If more than one blade lock screw has to loosened they
should be loosened evenly.
2. Cutting blade must be slid to the outside of the cutterhead for removal.
3. Insert new cutting blade from the outside of the cutterhead 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 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 wrench.
5. Be sure cutterhead can rotate freely, without coming into contact with the tube or pipe, when first
starting tool.
Power 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.
3. Connect the air supply.
4. For electric tools, be sure to connect the tool to a properly grounded outlet and if using an extension cord,
be sure that the extension cord is properly sized for the application. Failure to properly size an extension
cord can result in personal injury and/or harm to the electric motor
Operation of tool
1. Engage the ball valve (or switch) 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. Using 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 tools.
b. Engaging a rotating cutting blade with the work surface without feed (rubbing), creates excessive
heat build up.
4. 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.
5. Turn power supply off, so the motor no longer rotates the cutterhead, this will stop the tool.
6. Disconnect the power supply.
7. Release the draw rod nut and remove the tool from the work.

Tool limits
Size limits
1. Minimum inside diameter is 3.750”.
2. Maximum outside diameter is 14”.
3. Maximum wall thickness, 1-1/4”” with standard tooling.
4. Extremely thin walls may require special tooling to prevent deformation of diameter.
Material limits
1. Difficult materials may require the following to maximize blade life.
a. Lubrication such as cutting oils, soluble oils, soapy water, plain water, etc.
b. Slow the speed of air motor, using the ball 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 is set half way between open
and closed.
d. Fill lubricator, use a light weight air tool motor oil (s.a.e. 10).
e. For electric tools, inspect the cord for damage. If any damage is noted, the cord should be
replaced.
2. Gear housing grease.
a. There is no grease fitting on rental tools. This is because of the tendency to over grease. Excess
grease can back up into the air motor and cause failure.
b. A single pump from a grease gun after every two hundred hours of use is sufficient for all tools
equipped with a grease fitting.
c. Use grease NLGI # 2.
3. Lubrication for storage.
a. For air powered tools, 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 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 section six.
i. No special tools are required to perform complete service.
Servicing by manufacturer or agent
1. Factory service, return the tool to the factory address listed below.
2. Agent service, If applicable return tool to the agent listed below.
a. If unsure of agent contact the factory.
