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 slightly
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, re-
move 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 ham-
mers, 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
against the corner supports. Make sure the set up is
symmetric, with the corner supports in the correct
position, to prevent damage to the bender.

Maintenance Instructions

WARNING
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.
