TOBENDTUBING

1. Raise the swivel handle and position tubing into the guide groove. It is important that the tube is

engaged with the tube clamp to prevent tube slippage. (See Fig. 1).

2. Lower the swivel handle until the “0’s” on the form wheel and form lever are aligned, then pull the

handle down until the desired bend angle is obtained. Degree of bend is indicated when the “0”

mark on the form lever aligns with the degree mark on the form wheel. (See Fig. 2).

3. For ease in completing bends greater than 90° (180° max.), reposition the swivel handle by rotat-

ing counterclockwise. (See Fig. 3). An over-center position automatically locks the swivel handle in

place when bending force is applied.

90°BENDS

1. Measure from end of tube to where you want the ﬁrst bend, and place a mark on the tubing at that

exact point.

2. Position tube in bender. If the end from which you measured is left of the tube clamp, the

measured mark should be directly over graduation “L” located on the right side of the form lever.

(See Fig. 4).

3. If the end from which you measured is placed to the right of the tube clamp, the measured mark

should be directly over graduation “R” on the form lever. (See Fig. 5).

4. With a steady motion, pull the swivel handle around until the “0” mark on the swivel handle is

directly opposite the 90° mark on the form wheel. (See Fig. 5).

45°BENDS

1. Measure from end of tube to where you want the ﬁrst bend, and place a mark on the tubing at that

exact point.

2. Position tube in bender. If the end from which you measured is left of the tube clamp, the

measured mark should be directly over graduation “L” located on the right side of the form lever.

(See Fig. 4).

3. If the end from which you measured is placed to the right of the tube clamp, the measured mark

should be directly over graduation “R” on the form lever. (See Fig. 5).

4. With a steady motion, pull the swivel handle around until the “0” mark on the swivel handle is

directly opposite the 45° mark on the form wheel. (See Fig. 6).

DOUBLE45°OR90°OFFSETBENDS

When forming a tube offset, it is necessary to make two bends. Mark the tube at both bend locations before

proceeding. Wherever possible, use 45° bends.

FIGURINGOFFSETBENDS

1. Refer to the offset bend calculator chart (see last page). Note that the “Y” dimension in the chart

gives the total amount of offset required. The “X” dimension in the chart gives the length of tubing

you will use for a given application.

2. To ﬁgure out the length of tubing which is needed to meet your offset requirements, follow this

example: For a 45° angle with a 2-1/2” offset, refer to the chart under “Angle of offset 45°”. Next,

refer to the “Y” dimension and ﬁnd 2-1/2” offset. The ﬁgure to the right under “X” dimension will

be the length of tubing you will use. In this example, the required length is 3-17/32”.

3. Now determine where you want the center of the offset bend on the tube. Make a reference mark

“A” at this point. (See “A” on Fig. 7). From this point, measure the “X” dimension (length of tubing

determined in step 2) and make a mark “B.” You are now ready to make the bends.

NOTE: The “Offset Bend Calculator” chart allows you a “Y” dimension of up to 6 inches. If your offset

requirements should exceed this number, you must choose an offset from the table that is a multiple of the

offset you need. For example, if you have an offset requirement of 20", ﬁnd the multiple (5") on the chart

under dimension “Y”. Take the “X” dimension to the right of this and multiply by 4. This will be the length of

tubing you need for your offset. In this case it is 28-1/4".
