protective clothes, and other safety devices when appropriate.
Operate this tool only in accordance with specic operating instructions.
WARNING
WARNING: Do not override the dead-man switch on the power unit. Locking down,
obstructing, or in any way defeating the dead-man switch on the power drive unit may
result in serious injury.
Personal Protective Equipment
Use standard safety equipment such as: hard hats, safety shoes, safety harnesses,
protective clothes, and other safety devices when appropriate.

Do not wear loose clothing or jewelry.
Wear nonskid footwear.
Put long hair in a cap or a net to make sure hair does not get tangled in equipment.
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.
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.

Model 550 Tube Severing Tool
92-0116 Rev. 210906 9
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.
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.
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.
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 550 Tube Severing Tool series of tube cutters is designed to cut tubing in areas
where access to and around the tube is limited.
The Model 550 uses a cutter wheel to sever the tube. Normal operation does not produce
chips.
The Model 550 is powered by Tri Tool Inc. pneumatic, electrical or manual Drive Units.
The Model 550 features an automatic feed, which permits an even pressure on the cutting
wheel during operation.

5. MAINTENANCE
Periodically clean and coat all components with a light lm of oil. Use a clean, non-detergent
oil, preferably SAE 10 (90 SSU or lighter.)
Replace the Cutting Wheel if it is worn or damaged. The Cutting Wheel life depends upon
the tube material, wall thickness, and operator’s experience.
Replace short and long bearing plugs when they are worn, damaged, or if there are
scratches on the tube being cut.
