obstructing, or in any way defeating the deadman switch on the power drive
unit may result in serious injury.
Model 236B Single Point
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 rot ating 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.
St ay 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 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 muf flers 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
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.

92-1333 : Rev. 110404
Page 5
Model 236B Single Point
Disconnect the 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 your 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 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.

Turn the motor on.
Let the machine rotate very slowly for one revolution to verify that the tool bit clears
the OD of the pipe.
Adjust the cutting speed by opening the Flow Control V alve at the power supply
connection.
The actual machining operation will begin when the tool bit contacts the pipe.
If the pipe end is not square with the pipe axis, the tool bit will contact only a
small segment of the pipe during each revolution.
92-1333 : Rev. 110404
Page 13
Remove the machine from the pipe.
Check to see if any of the tool bits are dull or broken.
Damaged or worn tool bits are evident by increased feed pressure, visual
observation, poor surface finish, etc.
When the next bevel is going to be the same end preparation as the previous bevel,
install the machine and mandrel in the pipe and follow the same sequence of steps
that was used to completed the bevel.
When the next bevel is going to be different than the previous bevel, follow the
sequence in 'Adjustment of the Tool Block Assembly' section.
For changing the tool bit, follow the sequence in the 'Counter Boring Function'
section.
ADJUSTMENT OF THE TOOL BLOCK ASSEMBLY
Model 236B Single Point
While holding the tool block slide assembly , loosen the six (6) screws on the base
of the slide.
Reposition the slide assembly and tighten the six (6) screws. This will hold the slide
firmly against the plate.
T o adjust the bevel angle of the slide, loosen the locking screws on the sides of the
slide, pull the slide up to the required angle and tighten the screws, maximum angle
is 37° 30’.
INST ALLATION OF THE TOOL HOLDER AND INSERT
T o select the appropriate tool holder and Insert, reference the 'Tooling' section of
this manual.
Use of a dull Insert or Inserts not manufactured by T ri Tool Inc. may result in poor
performance and may constitute abuse of this machine and therefore voids the T ri
T ool Inc. factory warranty .
Slide the assembled tool holder with Insert into the tool holder slot on the tool block.
Install the tool holder with the Insert with the cutting edge toward the mandrel .
Lock the tool holder into position with the set screws on the side of the tool holder .

Install the mandrel inside the pipe and tighten the draw nut to force the jaw blocks
out against the inside diameter of the pipe.
In order to avoid cutting the jaw blocks during the machining operation, the
mandrel must be installed beyond the final end preparation location.
Advance the machine by turning the feed knob clockwise until the tool bit is slightly
inside the pipe.
Move the tool slide out until the tool bit contacts the ID of the pipe and tighten the
slide.
Turn the manual feed knob on the tool slide so that the tool bit clears the bore ID
and back the machine out of the pipe.
Securely lock the tool slide in position by tightening all six (6) of the radial adjust
screws on the slide assembly.

Turn the motor on.
Let the machine rotate very slowly for one revolution to verify that the tool bit clears
the ID of the pipe.
Adjust the tool bit into the cutting position, use the manual feed knob on the tool
slide.
Tighten the dovetail slide lock screw in the tool block when desired tool bit position
has been achieved.
This screw must be loosened and re-tightened whenever the dovetail slide
requires repositioning.
When it is not securely tightened, the tool bit may walk out of the cut.
Use 200 surface inches per minute (5080 surface millimeters per minute) for:
Stainless steels in general when no coolant is allowed, all heavy-wall tube
and some chrome/molybdenum steels.
Use 250 surface inches per minute (6350 surface millimeters per minute) for:
Mild steels and some thin-wall stainless steels when coolants are permitted
and applied.
Use 300 surface inches per minute (7620 surface millimeters per minute) for:
Aluminum and some thin-wall mild steel and tube with coolants.
BASIC FEED RECOMMENDA TION
Use very light feed for initial beveling or until a continuous cut is established.
This is very important for longer tool bit life when cutting through flame cut or
out of square pipe ends.
Use adequate feed, .003” (.08 mm) to .006” (.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” (.08 mm) to .006” (.15 mm) feed. Never
allow the tool bit to burnish the surface.
Reduced feeds and speeds will normally minimize chatter problems.
