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 Setup
1.
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).

Anchoring
This 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 Setup
1.
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.

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 Holes
1.
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 Operations
The 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.

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.
