HELPFUL TIP:
Once the learning curve provides familiarity with the characteristics
of the Eastwood Hydraulic Tubing Bender and how it reacts with the most commonly
formed tubing sizes, materials and bend amounts, it is extremely helpful to create a
series of “Templates” that can be used as patterns.
For example: if 2” Chromoly steel tubing is frequently used, it saves a great deal of time
and effort in future projects by creating templates in 22.5°, 45°, 90°, 120° & 180° and
more as needed. On these, mark the amount of material required to make each bend
and the amount of “springback” encountered.
• Slip the workpiece tube in place between the curved Die and Die Follow bar then
place the U-Clamp over the outer side of the workpiece tube
(FIG 14)
. Lightly
tighten the Tensioner Bolt if needed.
NOTE:
On thinner walled material, it may be helpful to place a small cut out
section of material being used between end of the Tensioner Bolt and outer side
of workpiece tubing to protect the surface and avoid creating possible dents or
damage.
• Begin exerting carefully modulated downward pressure on the Actuator Handle to
take up any lash and eliminate looseness then set the Pointer to indicate “0°” on
the Degree Plate
(FIG 15)
.
• Slowly and steadily apply downward pressure on the Actuator Handle to create a
curved bend in the workpiece.

Approx. 40° to 45° of tube bending angle is possible with each
full extension stroke of the Hydraulic Cylinder and the drive point
on the Die must be moved to continue the bend (Fig 16).

The Hydraulic Tubing Bender is equipped with a muli-function Power Switch. The ON
/ OFF Push Buttons
(FIG 12)
are located behind a hinged Cover that incorporates an
Emergency Stop Button, and serves as a Safety Lock-Out when latched
(FIG 13).
Swing
open the Cover to access the ON / OFF Push Buttons for normal use. Press the large,
red Emergency Stop Button in the event of a malfunction or emergency, or to set the
Button in the Safety Lock-Out position by latching the Cover in the closed position. Slide
the Button towards the Cover Hinge to un-latch.
Should a malfunction occur during the operation of the Bender,
hitting the red EMERGENCY STOP BUTTON will stop all motion
immediately.
