Ram
Extension
Figure 17 – Inserting the Ram Extension (Shown Open
Without Pipe For Clarity)
As the desired degree of bend is reached stop ad -
vancing the ram. Do not try to create a bend of more
than 90 degrees (per the angle indicator), this could
cause kinking of the pipe and other issues. A square
or other measuring device may be needed to mea-
sure exact bend angles. It is preferable to under
bend the pipe as it is easier to bend the pipe a little
more than to straighten it. When the ram is retracted,
the pipe may spring back, so you may need to slight-
ly compensate to get the desired angle.
5. With the bend complete, move the ON/OFF switch to
the OFF ( ) position. Retract the ram by turning the
release knob to the retract position.
6. Remove the pipe from the bender. If needed, remove
pins, corner supports and/or open the top wing. If
the former is stuck to the pipe, a block of wood or a
soft faced hammer can be used to tap the former off
the pipe. Do not use regular hammers, chisels or
other hardened tools to remove the former. They
can chip and damage the former and cause injury.
Straightening Bends
A straightening former is available to slightly reduce the
angle of a bend (up to approximately 10 degrees). Use of
the straightening former may deform the bend. In some
cases (such as 90 degree bends on 2
straightening former cannot be used. To use:
1. Place the straightening former on the end of the ram.
2. Place the pipe so that the bend sits against the
straightening former and the legs of the bend are

Maintenance Instructions
Maintain the hydraulic bender according to these
procedures for a longer product life and to reduce
the risk of injury from electrical shock and other
causes.
Cleaning
After each use, wipe any oil or dirt off of the bender and
formers with a clean, dry, soft cloth. Pay special attention
to the ram and piston to remove any dirt or debris that
could scratch polished parts or damage seals. If needed,
the formers and corner supports can be cleaned with a
wire brush.
Lubrication
Monthly, or more often if needed, apply a light machine oil
or grease to handle pivot points, wing hinge, and pins. Do
not apply oil to hydraulic system components.
Hydraulic Oil
Checking Level/Adding Hydraulic Oil
Before each use, check oil level. Place the bender on a flat
level surface with the ram fully retracted. Remove the oil
vent cap – oil should be even with the bottom of the fill
neck. If oil is needed, add Shell Tellus 32 Hydraulic Oil or
other equivalent high quality hydraulic oil and replace oil

symmetric, with the corner supports in the correct
position, to prevent damage to the bender.
