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

6. MAINTENANCE
All components should be cleaned and coated with a light lm of oil prior to use.
Figure 2: Chip clean up
When the SUREFIRE 4 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 bevel has been
completed.
Tool life may be severely shortened, unless chips and/or other debris that have been
deposited on the cutting head during the machining operations are removed.
Verify that there is adequate grease in the gear box. Gears and bearings are to be
lubricated using a lithium based grease.
Disassembly of a power unit voids warranty, except when performed by a TRI TOOL INC.

2. When the pipe end is not square to the pipe axis, the Tool Bit will contact only a
small segment of the pipe during each revolution.
3. To avoid tool bit damage, the feed rate should be very slow until the tool bit(s) is
in contact with the pipe continually during at least one full revolution.
4. Continue rotating the feed handle clockwise until the end of the pipe is
completely machined.
5. Discontinue feed and allow the head to rotate one (1) to three (3) revolutions to
improve nish of the prep surface.
6. Release the motor trigger to stop the head rotation.
7. Rotate the feed handle counterclockwise to separate the tool bit(s) from the pipe.
8. Rotate the feed handle counterclockwise until the tool bit to pipe relationship is
