SAFETY PRECAUTIONS
WARNING:
IN GENERAL
When using rotating head cutting equipment, basic safety precautions should always
be followed to reduce the risk of personal injury.
Operate this tool only in accordance with specific operating instructions.
Do not override the deadman switch on the power unit. Locking down, ob-
structing, or in any way defeating the deadman switch on the power drive unit
may result in serious injury.
DRESS CONSIDERATIONS
Use standard safety equipment. Hard hats, safety shoes, safety harnesses, protec-
tive clothes, and other safety devices should always be used when appropriate.
Use safety glasses. Do not operate cutting tools without eye protection.
Dress properly. Do not wear loose clothing or jewelry. They can be caught in rotat-
ing and moving parts. Avoid slippery floors or wear nonskid footwear. If you have
long hair, wear protective hair covering to contain it.
WORK AREA
Keep the work area clean. Cluttered work areas and benches invite injuries.
Consider the work area environment. Keep the area well lit. Keep electrical cords,
cables, rags, rigging straps, and etc. clear of rotating equipment. Do not use power-
cutting tools in the presence of flammable liquids and gasses.
Keep visitors away. Do not let visitors or untrained personnel at or near operating
tools. Enforce eye protection requirements for all observers.
Do not over reach. Keep proper footing at all times.
Stay alert. Watch what you are doing. Use common sense. Do not operate tools
when you are tired.

TOOL CARE
Maintain tools with care. Keep tools in good operating condition. Sharp tool bits
perform better and safer than dull tool bits. Well maintained tools function properly
when needed.
Check for damaged parts. If a tool has malfunctioned, been dropped or hit, it must
be checked for damage. Run no-load tests and feed function checks. Do a com-
plete visual inspection.
Electric motors. Use only with proper AC voltage power sources and observe all
normal electric shock hazard procedures.
Do not abuse power and control cords. Pulling or running over cords and cables
can result in electrical shock hazards and malfunctions. Keep control and power
cords out of all cutting fluids and water.
Hydraulic drives. Observe proper procedures for electrically driven power sources.
Avoid damage to hydraulic lines. Keep quick-disconnects clean. Grit contamination
causes malfunctions.
Air tools. Check the exhaust muffler. Broken or damaged mufflers can restrict air
flow or cause excessive noise. Use air motors only with a filtered, lubricated and
regulated air supply. Dirty air, low-pressure air or over pressure air will cause mal-
functions, including delayed starting.
AREA EQUIPMENT
Secure work. Whenever possible use clamps, vises, chains and straps to secure
pipe.
Make sure the tool is secured; it is safer to have both hands free to operate the tool.
TOOL USE
Use the right tool and tool bit for the job. Do not use a tool, which is incorrect for the
job you are doing.
Keep the tool bits fully engaged in the tool bit holders. Loose bits are a safety haz-
ard.

92-0579 : Rev. 080905
Disconnect power supply during setup and maintenance. Use all ‘Stop’ or Shut off’
features available when changing or adjusting tool bits, maintaining the tool, or when
the tool is not in use.
Remove adjusting keys and wrenches before applying power to the equipment.
Develop a habit of checking the tool before turning it on to make sure that all keys
and wrenches have been removed.
Do not force tools. Tools and tool bits function better and safer when used at the
feed and speed rate for which they were designed.
Do not reach into rotating equipment. Do not reach into the rotating head stock to
clear chips, to make adjustments, or to check surface finish. A machine designed to
cut steel will not stop for a hand or an arm.
Handle chips with care. Chips have very sharp edges and are hot. Do not try to pull
chips apart with our hands; they are very tough.
Avoid unintentional starts. Do not carry or handle tools with your hand on the oper-
ating switches or levers. Do not lay the tool down in a manner that will start the
drive. Do not allow the tool to flip around or move when adjusting or changing tool
bits.
Store idle tools properly. Disconnect tools from the power source and store in a safe
place. Remove tool bits for safe handling of the tool.

CAUTION:
CAUTION:
OPERATION
Select the tool bit required to machine the end configuration desired.
The use of dull tool bits or tool bits not manufactured by TRI TOOL Inc. may
result in poor performance and may constitute abuse of this machine and
therefore voids the TRI TOOL Inc. factory warranty.
General guidelines for selecting a tool bit. Selection of the tool bit should be based
on tubing material, tubing size, and how critical is it to have a near burr free end.
A standard entrance angle tool bit is recommended for carbon steel. These tool bits
also function well with some stainless steel applications where a near burr free end
is not a critical requirement.
A high entrance angle tool bit is recommended for most stainless steels. Generally
this is the most suitable edge geometry for about 90% of all the stainless steel
tubing applications.
An extra hook angle tool bit is recommended for stainless steels, which are very
soft. These stainless steels include materials like 316L, which have been bright
hydrogen annealed, vacuum annealed or annealed and Electro-polished. Electro-
polished stainless steel has a micro-thin surface, which is high in Cr. and Ni, which
makes it very soft, but tough and difficult to cut without a burr.
The M-42 tool bits are for use with the exotic alloys where the high heat resistance
is required to avoid burning the cutting edge of the tool bit. M-42 can improve the life
expectancy of the tool bit under some conditions on stainless steel. It should be
noted that M-42 tool bits are more brittle than the standard M-2 tool bits, therefore
there is a much greater risk of damaging the M-42 tool bit when installing the tubing
in the Tube Squaring Machine. Loss of tool bits from damaged edges may not off-
set the improved cutting life that those tool bits promised.
Some of the exotic alloys may require tool bits with both the extra hook angle as
well as the M-42 tool steel for heat resistance.
Insert the tool bit into the slot in the Cutting Head.
Ensure that the Model 301SP is disconnected from the power source before
installing a tool bit.

The normal position for the tool bit is illustrated below. This position is used for
.50” (12.7 mm) and smaller diameter tubing. This is the designed working position
of the tool bit and will leave virtually no burr with standard tubing. When working
with Electro-polished stainless steel tubing, slow cutting speeds must be used to
minimize the ID burr.
The tool bit may be reversed as illustrated. This reversed position may be used for
tubing with an ID greater than .50” (12.7 mm). With the extreme shear cutting action,
the burr on the ID will be virtually eliminated.
Tool Bit Installation
CAUTION:
NOTE: Minimum burr may be obtained with a slow RPM and a slow feed, which will
cut a continuous chip.
The cutting edge of the tool bit must be located on the radial centerline.
Do NOT install the tool bit backwards.

CAUTION:
NOTE:
Tool Bit Tightening
Tighten the set screws to secure the tool bit to the Cutting Head.
Select the proper size Saddle for the outside diameter of the tube or pipe to be
squared.
The size of the Saddle is determined by the outside diameter of the tube or
pipe to be squared.
Do not drop the Saddle. Always place a hand under the Saddle when
installing or removing it from the Model 301SP.
INSTALLING A SADDLE IN THE MODEL 301SP
Select a Saddle for the desired diameter of the tubing to be worked. Place the
Saddle half with the (2) two clearance holes in it in the front of the Housing. Thread
in the (2) Cap Screws that hold the Saddle half into the front of the Housing. Thread
the third Cap Screw into the side of the Housing and into the Saddle half. Tighten all
(3) three Cap Screws which retain the Saddle half in the front of the Housing.
Place the other Saddle half in the Housing. Run the Clamp Knob Assy in until it
lightly presses the second Saddle half against the first Saddle half. Thread the
Shoulder Screw in through the Clamp Knob Assy into the upper half Saddle. Retract
the second Saddle half by turning the clamp Knob Assy. Install the (2) two Button
Head Screws with the (2) two Flat Washers into the front of the Housing.
Insert the tubing to be worked on into the front of the Model 301SP. Move the tube or
pipe approximately 1/16” (1.6 mm) from the tool bit.

CAUTION:
CAUTION:
If the Machine has a Metabo Motor then the Speed Control located in the Trigger
Guard is used to adjust the cutting speed.
If the Machine has a Metabo Motor then the Two Speed Gearbox Knob
should be in the position shown. If the Knob does not snap into the desired
position, turn the chuck by hand slightly until the knob snaps into place as
shown.
If the Machine has a Metabo Motor then the Impact Knob should be in the
position shown.
If the Machine has a Metabo Motor then the Rotation Control Switch should
be in the position shown. The 'R' LED on the LED Display should be lit.
Refer to Cutting Speeds and Feeds Section.
In order to obtain a minimum burr tube end, it is essential that heat build up be
avoided. When either the tube or the tool bit get hot, then the tube material starts to
flow or push away from the tool bit edge in the form of a burr, instead of being cut
cleanly with a minimum burr. Avoid the conditions which generate excessive heat
by keeping the RPM's low; excessive cutting speed will generate unwanted heat.
Keep the chip curling loose by avoiding an excessive depth of cut. A dull tool bit will
not do the job right, so be sure that there is a sharp tool bit mounted in the Machine.
Rotate the Feed Handle clockwise to bring the Cutting Head and tube closer
together. The actual machining operation will begin when the tool bit contacts the
tube or pipe.
If the tube end is not square to the tube axis, the tool bit will contact only a small
segment of the tube during each revolution. To avoid tool bit damage, the feed rate
should be very slow until the tool bit is contacting the tube continually during at least
one revolution.
Adjust cutting RPM with the Speed Control Trigger is just above the required cutting
speed as the tool bit enters the cut. The tool will slow down slightly as the cutting
load increases, apply additional power to hold the cutting speed.
Observe the chip as the Machine is cutting. The ideal chip will come off in a loose
pig tail spiral. A chip that is coming off in a tight straight spiral normally indicates that
the feed is too heavy. A straight or slightly curled chip normally indicates that the
feed is too light. Back off the feed as required to break the chips and let them fall
away.

16
TRI TOOL INC.
92-0579 : Rev. 080905
CAUTION:
If a significant amount of stock must be removed, occasionally back off out of the cut
and let the tool bit spin free in the air to cool.
Continue rotating the Feed Handle clockwise until the end of the pipe is completely
machined.
Be careful not to let the tool bit cut into the Saddle or the Saddle Adapter.
Discontinue feed and allow the Cutting Head to rotate one time for stainless steel
and up to three times for other materials to improve the finish of the prep surface.
Never let a tool bit ‘rub’ the surface of a stainless steel tube without cutting. This will
work harden the material and it will be difficult for the tool bit to get under the
material in order to finish the cut. This will also cause excessive tool bit wear.
For precision depth of cutting, engage the tool bit into the end of the tube and use
the indicator sleeve located on the Feed Handle to check the depth of the cut. The
graduations are in .005” increments on one half of the sleeve and .13 mm
increments on the other half.
Rotate the Feed Handle counterclockwise to separate the Cutting Head and the
tube.
In order to stop the Cutting Head rotation, release the Trigger.
Continue to rotate the Feed Handle counterclockwise until the Cutting Head clears
the tube or pipe by at least 1/8” (3.2 mm) or more.
Loosen the Clamp Knob Assy to release the tube or pipe.

CUTTING SPEEDS AND FEEDS
BASIC FEED RECOMMENDATIONS
Use very light feed for initial facing or until a continuous cut is established.
This is very important for longer tool bit life when cutting through flame cut or
out-of-round pipe ends.
Use adequate feed, .003” to .006” (.08 mm to .15 mm) per revolution thereafter, to
establish a continuous chip cut. If the feed is too light, only light stringer chips will be
removed. If the feed is too heavy, the drive will start to overload and the chip will
start to have a rough or torn appearance.
Stainless steel, which work hardens, must be worked with a heavy enough feed to
stay under the work hardened surface (.003” to .006” or .08 mm to .15 mm feed)
Never allow the tool bit to burnish the surface.
Reduced feeds and speeds will normally minimize chatter problems.
