This machine and its components are very heavy. Get lifting help or use power lifting equip-ment such as a forklift to move heavy items.

Eye injury hazard! Always wear safety glasses when using this machine.

The machine must be fully assembled before it can be operated. Before beginning the assembly process, refer to Needed for Setup and gather all listed items. To ensure the assembly process goes smoothly, first clean any parts that are cov-ered or coated in rust preventative.

Assembly

Frame Assembly Setup1. Place frame base (see Figure 4) on stand

and verify holes are aligned.

2. Place lower frame link on top of frame base as shown in Figure 4 and verify both are aligned.

3. Verify swing lever and ratchet are right side up, and swing lever is able to rotate almost a full 180° (see Figure 4).

4. Insert frame spacer into swing lever and collar, then position frame spacers between upper and lower frame links (see Figure 4).

AnchoringThis machine MUST be anchored to the floor before operating. Anchoring machinery to the floor prevents tipping or shifting that may occur during operation.

Lag shield anchors with lag screws (Figure 3) are a popular way to anchor machinery to a concrete floor, because the anchors sit flush with the floor surface. However, anytime local codes apply, you MUST follow the anchoring methodology speci-fied by the code.

5. Insert M20-2.5 x 175 hex bolts with 20mm flat washers through upper frame link, frame spacers, swing lever, collar, lower frame link, frame base, and stand (see Figure 4). Secure with 20mm flat washers and M20-2.5 hex nuts (only hand tighten for now).

6. Insert frame pin through upper and lower frame links (see Figure 4).

7. Insert drive pin into #5 hole as shown in Figure 4.

8. Fully tighten both hex nuts installed in Step 5. Verify drive pin and frame pin are able to slide through their respective holes.

9. Raise swing lever to middle of frame spacer and lock into position by tightening set screw on collar with 4mm hex wrench.

10. Install bend angle indicator, 20mm flat wash-er, and M20-2.5 hex nut onto lower frame link (see Figure 4) and hand tighten.

Note: This nut should never be tightened with a wrench. This allows the bend angle indica-tor to be adjusted while bending.

11. Verify frame is assembled as shown in Figure 5.

Drive Link Assembly Setup1. Place both drive links (see Figure 6) on their

side with "TOP" stamp facing same direction.

Note: Drive link "TOP" stamp must face same direction on both drive links since three of four drive holes are offset to the right.

2. Insert M14-2 x 110 hex bolts with 14mm flat washers into upper drive link holes shown in Figure 6.

3. Install drive link spacers (see Figure 6) over hex bolts and insert threaded end of hex bolts through lower drive link holes.

4. Secure hex bolts with 14mm flat washers and M14-2 hex nuts, and hand tighten.

5. Insert frame pin and drive pin through drive link holes shown in Figure 6.

Note: The frame pin is shared between assemblies for alignment purposes only dur-ing setup.

6. Fully tighten both hex nuts installed in Step 4. Verify drive pin and frame pin are able to slide through their respective holes.

7. Verify drive link is assembled as shown in Figure 7.

Bender Assembly Setup1. Remove frame pin and drive pin from drive

link assembly (see Figure 8).

2. Insert frame pin hole portion of drive link assembly between frame pin holes of frame assembly (see Figure 8). Verify alignment of all four frame pin holes.

3. Insert frame pin through frame assembly and drive link assembly (see Figure 8).

4. Insert drive pin into drive link assembly (see Figure 8).

Note: Drive pin location is determined by the die set being installed.

5. Verify bender is assembled as shown in Figure 8 before installing die sets.

Die Sets With Drive Holes1. Verify all pins are completely seated and die

set is installed according to manufacturer's instructions (see Figure 9).

2. Place tubing into die set and tighten U-strap bolt (see Figure 9).

3. Install handle onto swing lever and rotate swing lever counterclockwise until it stops.

4. Engage ratchet onto outer drive link spacer, as shown in Figure 10.

5. Lightly pull handle clockwise to preload tub-ing. DO NOT pull hard enough to bend tubing.

Bending OperationsThe T30860 is capable of bending round tubing between 1⁄2"–2" in diameter, and square tubing between 1"–2" in diameter. The machine supports die sets with or without drive holes.

Die Sets Without Drive Holes1. Verify all pins are completely seated and die

set is installed according to manufacturer's instructions (see Figure 13).

15. Rotate swing lever and ratchet counterclock-wise as shown in Figure 12.

16. Remove handle from swing lever and insert diagonally through drive link assembly spac-ers (see Figure 12).

17. Pull handle counterclockwise until followbar releases tubing.

18. Carefully remove tubing from assembly.

6. Rotate bend angle indicator until die set pointer is at 0° (see Figure 11).

7. Pull handle clockwise with enough force to bend tubing until swing lever stops (see Figure 10 on Page 4).

8. Slowly rotate handle counterclockwise until ratchet disengages.

Note: If ratchet disengages too quickly the tubing could move out of position.

9. Re-engage ratchet at next closest tooth and pull handle clockwise with enough force to bend tubing until swing lever stops.

10. Repeat Steps 6–8 until last ratchet tooth is engaged.

11. Rotate handle counterclockwise until swing lever stops.

12. Remove drive pin from drive link assembly (see Figure 8 on Page 4).

13. Rotate drive link assembly counterclockwise, then insert drive pin into next drive hole in forming die. Verify drive pin is fully seated before continuing.

Note: Take care to maintain tube position when making adjustments.

14. Repeat Steps 6–12 until desired bend angle is reached.
