Donotusepower-cuttingtoolsinthepresenceofammableliquidsandgases.
Do not let visitors or untrained personnel near tools that are in use.
Ensure all observers wear eye protection.
Keep proper footing at all times.
2.5 Area Equipment
Secure the pipe with clamps, vises, chains or straps.
Ensure that both sides of the pipe at the cut site is fully supported so that the pipe will
not move after the cut is completed. Long lengths of pipe may be under load and the
separation of the pipe can release pressure. This pressure can cause both sides of the
pipe to move.
2.6 Tool Care
Keep tools in good operating condition. Sharp tool bits perform better and are safer than
dull tool bits.
Do not use damaged tools. Always check your tools for damage especially if a tool has
malfunctioned, been dropped or hit, check it for damage.
Before you start operating the equipment, do no-load tests and feed function checks.
2.7 Tool Use
Use the right tool and tool bit for the job. Contact Tri Tool to help with your application.
Keep the tool bits fully engaged in the tool bit holders. Loose bits are sharp and can
cause cuts or punctures.
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. Check
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
recommended speeds.
Do not reach into rotating equipment.
Do not reach into the rotating head stock to remove chips, to make adjustments, or to
checkthesurfacenish.

6. OPERATION
DANGER
DANGER: Do not override the deadman switch on the power unit. Locking down,
obstructing, or in any way defeating the deadman switch may result in serious injury.
6.1 Select and Install a Tool Bit
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 void the TRI TOOL Inc. factory warranty.
General guidelines for selecting a tool bit.
Determine the tubing material, tubing size, and how critical is it to have a near
burr free end.
• CARBON STEEL - use a standard entrance angle tool bit. These tool bits
also function well with some stainless steel applications where a near burr
free end is not a critical requirement.
• MOST STAINLESS STEEL - use a high entrance angle tool bit for most
stainless steels. Generally this is the most suitable edge geometry for about
90% of all the stainless steel tubing applications.
• SOFT STAINLESS STEEL- An extra hook angle tool bit is recommended for
soft stainless steel. These stainless steels include materials like 316L, which
have been bright hydrogen annealed, vacuum annealed or annealed and
Electro-polished. Electropolished stainless steel has a micro-thin surface,
whichishighinCrandNi,whichmakesitverysoft,buttoughanddifcultto
cut without a burr.
• EXOTIC ALLOYS - Use the M-42 tool bits when 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.
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 offset 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.
6.2 Install Tool Bit
WARNING
WARNING: Check that the Model 301SP is disconnected from the power source
before you install a tool bit.

1. InsertthetoolbitintotheslotintheCuttingHead,refertotherstpartof
Fig 3. Do not install the tool bit backwards.
2. Tighten the set screws to secure the tool bit to the Cutting Head.
• The cutting edge of the tool bit must be located on the radial
centerline.
• This position is used for .50” (12.7 mm) and smaller diameter tubing.
Virtually no burr is left on standard tubing. Use slow cutting speeds
with Electro-polished to minimize the ID burr.
• The tool bit may be reversed, refer second part of Fig 3. Use the
reversed position for tubing with an ID greater than .50” (12.7 mm). The
extreme shear cutting action will virtually eliminate the burr on the ID.
• Minimum burr may be obtained with a slow RPM and a slow feed,
which cuts a continuous chip.
Figure: 3. Tool Bit Installation
6.3 Select and Install a Saddle
1. SelectaSaddle,refertoSection8,SaddleSets.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.
2. PlacetherstSaddlehalfwiththetwoclearanceholesinthefrontofthe
Housing.
3. Thread in the two Cap Screws to hold the Saddle half into the front of the
Housing.

7. Run the Clamp Knob Assy in until it lightly presses the second
SaddlehalfagainsttherstSaddlehalf.
8. Thread the Shoulder Screw in through the Clamp Knob Assy into
the upper half Saddle.
9. Retract the second Saddle half by turning the clamp Knob Assy.
10. Install the two Insert Nuts with the two Flat Washers into the front of
the Housing.
11. Insert the tubing to be worked on into the front of the Model 301SP.
12. Move the tube or pipe approximately 1/16” (1.6 mm) from the tool bit.
13. Tighten the Clamp Knob Assy to tighten the tube in the Saddle.
14. Connect the Model 301SP to the power source and pull the Trigger
to start rotation of the Cutting Head.
15. If the Machine has a Metabo Motor, use the Speed Control in the
Trigger Guard to adjust the cutting speed.
CAUTION
CAUTION: Do not let the tool bit touch the tube or pipe. This will damage the tool bit
or the Tube Squaring Machine when power is applied.

16. For Metabo Motor only
• The Two Speed Gearbox Knob should be in the position in Fig 7. If the
Knob does not snap into the desired position, turn the chuck by hand
slightly until the knob snaps into place.
• The Impact Knob should be in the position shown.
• The Rotation Control Switch should be in the position shown. The ‘R’ LED
on the LED Display should be lit.
17. Use the Feed Handle to feed the Shaft with the tool bit into the work
18. In order to obtain a minimum burr tube end, avoid heat build up. When
eitherthetubeorthetoolbitgethot,thetubematerialstartstoow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 RPMs low. Excessive cutting speed will
generate unwanted heat.
19. 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.

20. 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.
21. 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.
22. 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.
23. 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.
24. Back off the feed as required to break the chips and let them fall away.
25. Ifasignicant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.
26. Continue rotating the Feed Handle clockwise until the end of the pipe is
completely machined.
27. Be careful not to let the tool bit cut into the Saddle or the Saddle Adapter.
28. 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nishoftheprep
surface.
29. Never let a tool bit ‘rub’ the surface of a stainless steel tube without cutting.
Thiswillworkhardenthematerial.Soitwillbedifcultforthetoolbittoget
underthematerialtonishthecut.Thiswillalsocauseexcessivetoolbit
wear.
30. 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.
31. Rotate the Feed Handle counterclockwise to separate the Cutting Head and
the tube.
32. Release the Trigger to stop the Cutting Head rotation,.
33. 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.
34. Loosen the Clamp Knob Assy to release the tube or pipe.
