TRI TOOL INC. Warranty
All products manufactured by Tri Tool Inc. are warranted to be free from defects in materials
and workmanship under normal use. Effective October 12, 2018, the period of this warranty
shall be three years from the date of shipment for all products, except for welding and
custom equipment which shall be one year from the date of shipment.
The purchaser shall bear all shipping, packing and insurance costs and all other costs to
and from a designated repair service center. The product will be returned to the purchaser
freight prepaid and billed to the purchaser.
This warranty is not transferable and will not apply to tool bits or other consumables, or to
those products that have been misused, abused, or altered without the express permission
in writing by Tri Tool Inc.
Neither this warranty nor any other warranty, expressed or implied, including implied
warranties of mechanical ability, tness for a particular use, or merchantability, shall
extend beyond the warranty period. No responsibility is assumed for any incidental or
consequential damages.
Some states do not allow limitations on how long an implied warranty lasts and some states
do not allow the exclusion or limitations incidental or consequential damages, so the above
limitation of exclusion does not apply to all purchasers. This warranty gives the purchaser
specic legal rights. Other rights vary from state to state.
Tool Bit Resharpening Policy
Tri Tool Inc. can not resharpen badly gouged, chipped, or broken tool bits. Check the tool
bits before you send them and package them well. Within two working days of receipt, the
tool bits are evaluated and the customer is contacted for authorization.
The customer will receive a price and a scheduled return shipment date. The price structure
is available from your Tri Tool Inc. sales representative.
Tool bits that are not suitable for resharpening are returned with the tool bits that were
resharpened, unless Tri Tool Inc. is instructed otherwise.
The customer is responsible for shipping charges to and from Tri Tool Inc.
This policy only covers tool bits manufactured by Tri Tool Inc.

2.2 PERSONAL PROTECTIVE EQUIPMENT
• Use standard safety equipment such as: hard hats, safety shoes, safety
harnesses, protective clothes, and other safety devices when appropriate.
• Wear safety glasses.
• Do not wear loose clothing or jewelry.
• Wear nonskid footwear.
• Secure long hair.
2.3 PERSONNEL
• Only personnel who are trained or are being trained may operate the
equipment.
• Keep the operation manual available where the equipment is used.
• The operator must read the operation manual before using the equipment.
• The equipment must be operated in accordance with the manual information.
• The operator must follow the safety precautions in this manual and good
engineering practices to reduce the risk of injury.
• Before using the equipment, the operator must ensure that all safety
messages on the equipment are legible.
2.4 WORK AREA
• Keep the work area clean.
• Keep the area well lit.
• Keep items such as; electrical cords, cables, rags, rigging straps, away from
rotating equipment.
• 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.
DANGER
DANGER: Do not wear gloves when you use operate the equipment.
If you are using the index trip mechanism, a glove may be caught or
pulled into the pinch point created by the equipment head. This will
result in serious personal injury.

Model 208B BEVELMASTER®
92-1482 Rev. 190410
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.

TRI TOOL INC.
92-1482 Rev. 190410
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.
• Handle chips with care. Chips have very sharp edges and are hot. Do not try
to pull chips apart with bare hands.
• Store tools properly. Disconnect tools from the power source, remove the tool
bits, and store in a safe place.

3. GENERAL DESCRIPTION
The Model 208B BEVELMASTER® is a Pipe Beveler designed for facing,
beveling and/or counterboring the ends of pipe and/or tubing in preparation for
welding.
These machining operations may be performed either simultaneously or
separately.
Pipe weld end preparations that meet all existing conventional codes including
the more stringent nuclear codes may be machined using the Model 208B.

3.1 DESIGN AND OPERATING FEATURES
The various interchangeable jaw blocks and ramps secure the Model 208B Pipe
Beveler to pipe and tubing that have an inside diameter ranging from 1.63”
(41.4 mm) through 8.63” (219.2 mm).
Beveling pipe and tubing with an inside diameter of 1.5" (31.1 mm) requires a 2"
Mandrel Assembly. This Assembly is not included with the Standard Machine.
The expanding mandrel provides fast, accurate self-centering and alignment to
the pipe or tubing to be machined.
The Model 208B accepts the reaction torque generated by the machining
operations through the mandrel.
No additional restraining devices are required.

5. OPERATION
5.1 GENERAL COMMENTS
Always read the operating instructions before you operate the Model 208B
BEVELMASTER®.
A FRL (Filter/Regulator/Lubricator) is required to protect the warranty on all TRI
TOOL INC. air or hydraulic driven tools.
The motor warranty is void if damage occurs from contaminated air or lack of
lubrication.
The FRL unit must be maintained as required. The frequency will depend on the
basic air supply. Keep the water trap drained, lter cleaned and the lubricator oil
reservoir lled so there's a drop of oil every two (2) to ve (5) seconds.
If the unit is to be left idle for 24 hours or more after being run on ‘wet’ air, squirt
oil into the air motor inlet and run the motor for two (2) to three (3) seconds.
This will prevent rusting and ‘freezing’ of the rotor vanes.
For Hydraulic Motors refer to their ‘Operator’s Manual’ for specics.
When the unit is operated in the vertical position, cutting head up, turn it upside
down and remove the chips and/or other debris after each cutting operation has
been completed.
Tool life may be severely shortened, unless chips and/or other debris are
removed.

5.2 GETTING STARTED
1. Select the recommended jaw blocks and/or ramp set for the pipe size to be
machined. Refer to section 9, Jaw Blocks and Ramps.
2. Install the mandrel assembly into the pipe.
CAUTION
CAUTION: To avoid cutting the jaw blocks, install the mandrel
beyond the location of the nal end preparation.
3. Tighten the draw nut refer to (Fig. 4) to force the jaw blocks out to the inside
diameter of the pipe or tube.

LOCATION
Figure: 4. Location of the Draw Nut
4. Select the tool bit(s) required to machine the pipe to the conguration desired.
Use of dull or improperly designed 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.
5. When performing any multiple machining operation such as facing, beveling,
and/or counterboring, install the counterbore tool bit to ‘lead’ the bevel tool bit.
6. Attach the tool holders to the Model 208B.
7. Insert the tool bit(s) into the slot(s) in the tool holder(s).
8. The cutting edge of the tool bit(s) must be located on the radial centerline.
9. Ensure that none of the tool bits are installed backwards.
10. Tighten the set screws to secure the tool bit(s) to the tool holder(s).
