SAFETY PRECAUTIONS
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 specic operating instructions.
Do not override the deadman switch on the power unit. Locking down,
WARNING:
DRESS CONSIDERATIONS
obstructing, or in any way defeating the deadman switch on the power drive
unit may result in serious injury.
Model 301SP Tube Squaring Machine
Use standard safety equipment. Hard hats, safety shoes, safety harnesses,
protective 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
rotating and moving parts. Avoid slippery oors 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 ammable 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
complete 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 uids 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 mufer. Broken or damaged mufers can restrict
air ow or cause excessive noise. Use air motors only with a ltered, lubricated
and regulated air supply. Dirty air, low-pressure air or over pressure air will cause
malfunctions, 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
hazard.

Model 301SP Tube Squaring Machine
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 nish. 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
operating switches or levers. Do not lay the tool down in a manner that will start the
drive. Do not allow the tool to ip 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.

GENERAL DESCRIPTION
The Model 301SP Tube Squaring Machine is a lightweight, portable machine
designed for facing and squaring .125” to 1.050” (3.2 mm to 26.7 mm) outside
diameter tubing with an ability to handle up to 1/8” (3 mm) thick wall.
The Model 301SP features an integral, variable speed 115 VAC Electric Motor, an
integral, variable speed 220 VAC Electric Motor and Air motor or a Battery powered
Electric Motor.
Precision inside diameter Saddles hold the tubing round to accurately square and
face the tubing with a minimum burr.
The Machine accepts its own torque through the Saddle Clamping system.
The Cutting Head accepts Squaring Tool Bits.
All required tools for operation of the Model 301SP are supplied with the Machine.

MAINTENANCE
All components should be cleaned and coated with a light lm of oil prior to use.
Use a clean, non-detergent oil, preferably SAE 10 (90SSU) or lighter.
The air supply for the 301SP with an Air Motor should include an adequate lter,
regulator and lubricator (FRL).
The Air Motor warranty is void if damage occurs from contaminated air or
NOTE:
lack of lubrication.
If the Model 301SP is operated in the vertical position (Cutting Head up), it should
be turned upside down and the chips and/or other debris removed after each cut
has been completed.
Tool life may be severely shortened, unless chips and/or other debris that
NOTE:
have been deposited on the Cutting Head during the machining operation are
removed.
Disassembly of the Model 301SP will void the warranty, except when performed by
a TRI TOOL Inc. designated repair technician.

OPERATION
Select the tool bit required to machine the end conguration desired.
The use of dull tool bits or tool bits not manufactured by TRI TOOL Inc. may
CAUTION:
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 difcult 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
CAUTION:
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
Minimum burr may be obtained with a slow RPM and a slow feed, which will
NOTE:
cut a continuous chip.
The cutting edge of the tool bit must be located on the radial centerline.
CAUTION:
Do NOT install the tool bit backwards.
