Pivot Link Adjustment Instructions
IMPORTANT: Your Port-O-Bender
®
incorporates an advanced new Micro-Adjust system that enables you to adjust the
gripping tension on material faster and easier than ever. The Pivot Links have been pre-set at the factory for average
holding capacity and ease of operation. However, it's important that you readjust your Port-O-Bender
®
to your
stock thickness. Your Port-O-Bender
®
may also need periodic adjustment due to extreme weather and/or working
conditions. It is important that you follow these steps when you adjust your Port-O-Bender
®
to ensure proper gripping
tension and maximum performance.
First check the uniformity of the clamping pressure along the entire length
of your Port-O-Bender
®
by using the following method.
TO TEST —
Cut some narrow strips of aluminum or use strips from the stock you will be
using and lock one under
each shoe casting as indicated in Figure 1. Then
lightly pull the material to determine the tightness and uniformity of each
Pivot Link. Refer again to Figure 1. If the material can be moved when the
Port-O-Bender
®
handle is locked or if it requires excessive pressure to lock
the handle down on the material then the Pivot Links may need adjustment.
NOTE: All adjustments are
made with the Port-O-Bender
®
in the “open”
position. All adjustments are
tested with strips of material placed in the
Port-O-Bender
®
in the “locked” position.

TO ADJUST (Optional method)—
As an alternate method you may use a
5
/
8
" open-end wrench
directly on the Pivot Link Stud by turning 1/4 turn either
COUNTER-CLOCKWISE to INCREASE locking tension or
CLOCKWISE to DECREASE locking tension. (See Figure 3).
Repeat test step above to check tension.
TO ADJUST —
Insert the
3
/
16
" hex wrench provided into the Pivot Link Stud through
the access hole in the upper link. (See Figure 2). Turn 1/4 turn
either
COUNTER-CLOCKWISE to INCREASE locking tension
or
CLOCKWISE to DECREASE locking tension.
Repeat test step above to check tension.
