To begin using the tool:
1. As a standard practice, drain water from the air compressor
tank and air lines prior to use each day (reference your
compressor operators manual for detailed instructions).
2. Install a 1/4" NPT male connector (not included) into the air
inlet port on the tool (see Figure 2). Note: Use Teflon®
Tape on all threaded connections.
3. Turn on the air compressor and allow it to build up pressure.
Keep hands and body away from
moving parts.
4. Adjust the air compressor's regulator or the supply line
regulator to 90 PSI.
5
Lubricate the tool (see user-maintenance instructions).
6. Connect the tool to the air hose quick coupler. NOTE: It is
recommended that a whip hose with a swivel (P012-079SP - not included) be used to prevent twisting,
kinking, and excessive wear to the air hose (see figure 1 for recommended connections).
7. Place the side blades on the edge of the top side of the workpiece (see Figure 3). NOTE: Always lubricate the
material that is being cut. Use standard machine oil on steel and mineral
spirits on aluminum.
8. Squeeze the trigger gently to start the tool. Move the tool forward keeping the
side blades flush with the workpiece surface. Tool speed is increased by
increasing pressure on the trigger. NOTE: Do not force the tool. Too much
pressure can cause the blades to break or bind. Too little pressure will
cause the blade to not cut properly.
This tool is capable of propelling materials such as metal
chips when in use. Always wear ANSI Z87.1 approved safety goggles when
using this tool.
Edges and pieces of the workpiece are sharp. Wear gloves to avoid injury.
9. When finished cutting, remove tool from the workpiece while the motor is still running. Release the trigger to
stop the tool.
Replacement of blades
Always disconnect the tool from the air source before changing the blades or lubricating.
Do not operate the tool if the cutting head and blades are not in place and tightened.
1. Loosen the 3 allen screws (G) on the cutting head (H). Pull the cutting head straight out while turning it back and
forth to release it from the motor (see figure 4).
NOTE: Refer to Figure 5 for steps 2-11.
2. Remove the front 2 allen screws that hold the blades in place, being careful not
to loose the spacers (B & E) or the nuts (F) that are on the end of the screws.
3. Remove the 2 side blades (A & D), center blade (C) and spacers (B & E).
4. Lay out the new blades as shown in Figure 5.
5. Lubricate and then insert spacer (B) into the center blade (C).
6. Reassemble the blades into the cutting head by placing the center blade (C) on
top of side blade (A) then place side blade (D) on top of center blade (C).
