1. Select and install proper tail rollers. To bend 1 1/2 in. (38 mm) OD
tubing, use the fixed tail roller in the up position. For 2 in. (50 mm) OD
tubing, use the fixed tail roller in the down position. (See Figure 1.)
To bend 1 in. (25 mm) OD tubing, use the 1 in. (25 mm) removable tail
roller, securing pin in lower pin hole (up position). For 1 1/4 in. (32
mm) OD tubing, use the 1 1/4 in. (32 mm) removable tail roller, securing
pin in upper pin hole. Align roller with the inside of the unit. (See Figure

Tubing Layout
With this bender, you can form single, offset, and other bends. This section contains information for measuring and
marking the tubing prior to bending. NOTE: Make all marks 360° around the tubing.
Single 90° Bend
1. Place a reference mark at the end of the tubing from which your measurement begins.
2. From the reference mark at the end of the tubing, measure the desired length for the bend. Make a measurement
mark on the tubing.
3. Subtract the bend deduction distance (see Table 2 on page 9) from the measurement mark and make a bend
mark. (The bend deduction distance is a length that compensates for the bender and tube clamp design.)
4. To bend tubing, see Bending on page 11.

The Measure-Bend Method
1. Follow Steps 1 to 4 above for a Single 90° Bend.
2. Using the center line of the previous 90° bend as your
second reference mark, repeat Steps 2 to 4 for the second
90° bend.
EXAMPLE: Using 1 1/2 in. OD tubing, make two 90° bends
with measured length distances of 18 in. between bend marks.
(See Illustrations 2 and 3.)
1. From the reference mark at the end of the tubing, measure
18 in. and make a measurement mark.
2. The bend deduction distance for 1 1/2 in. OD tubing in
Table 2 is 9 7/8 in.
3. 18 in. – 9-7/8 in. = 8-1/8 in. Make the first bend mark at

Making Offset Bends
NOTE: Make all marks 360° around the tubing.
1. Make a reference mark at the end of the tubing from which
your measurement begins.
2. From the reference mark at the end of the tubing, measure
the desired length for the bend. Make a measurement
mark on the tubing.
3. Subtract the clamp distance (see Table 4) from the first
measurement mark and make a bend mark.
4. Determine the length of tubing (L) consumed in the offset.
See Table 5 or use one of the offset bend allowances
referred to in Table 6. (See Illustration 5.)
5. From the first bend mark, measure the distance required
for the offset bend allowance and make a second bend
mark.
6. Check for proper bend direction and tube orientation. To
bend tubing, see Bending on page 11.

EXAMPLE: Using 1 1/2 in. OD tubing, make an offset bend
beginning 14 in. from the end of the tube with a 20-in. offset
dimension (O) and a 30° offset angle (E). (See Illustration 6.)
1. From the reference mark at the end of the tubing, measure
14 in. and make a measurement mark.
2. The clamp distance for 1 1/2 in. OD tubing in Table 4 is
3-1/2 in.
3. 14 in. – 3-1/2 in. = 10-1/2 in. Make the first bend mark at
10-1/2 in.
4. The 20 in. offset bend is not in Table 5. Calculate the center-
to-center distance by multiplying 20 in. by the factor in Table
6 for a 30° offset, 2.000. 20 in. 3 2.000 = 40 in.
5. From the first bend mark, measure 40 in. and make the
second bend mark.

Springback
Bending the tubing approximately 3° beyond the desired angle is
necessary to compensate for tubing springback.

Bending
1. PresstheBENDorUNLOADfunctionkey.Rotatethebendshoe
until the proper reference notch on the bend shoe is aligned with the
pointeronthefaceplate.(SeeFigures5and6.)Notethedifference

should hang vertically from the bend shoe.
NOTE: If the bend shoe stops at 110° or –99°, reset the pendant
display by pressing the ZERO SET function key. Then, press the
BEND or UNLOAD function key to rotate bend shoe.
2. Insert tubing through tube clamp with reference mark toward the left
(see Tubing Layout, page 8), making sure tubing is positioned over
tower and tail rollers. Press the JOG function key until tubing rests
on tail roller and fits tightly. Press the ZERO SET function key. This
process ensures the bender is set correctly for bending.
3. PresstheUNLOADfunctionkeyuntilthetubingcanbemovedby

tower stops firmly against bridge. (See Figure 8.)
6. Tobend,pressandholdtheBENDorJOGfunctionkeyuntil

CAUTION! Bending in excess of 110° may damage tubing and bender.
7. To remove tubing, stand clear of the handle lock, and press and
holdtheUNLOADfunctionkey(approximately5°)untilrollertower

The two roller alignment screws, located on the rear side plate of the bridge assembly (see Figure 11), allow adjustment
of the bridge assembly to keep the roller towers and bend shoe aligned. Misalignment can lead to sidemarking.

Roller Adjustment Screws
The two roller adjustment screws on the left side of the bender
(see Figure 10) change the pressure applied to the tubing. The
factory setting (as viewed from the front) for these screws is the
gap measured between the top of the bender frame leg and the
bottom of the screw blocks.
