Adjusting
Counterweights
The counterweights add leverage to ease the
effort needed to bend thicker workpieces.
The gauge of the workpiece determines where on
the arm the counterweight is placed. For example,
the counterweight would be positioned low on the
arm for bending 20 gauge steel and high on the
arm for bending 12 gauge steel.
The counterweights simply slide up and down the
shafts and the lock collars hold them in place.
To adjust the counterweights:
DOWN
1.
Push up on the counterweight to relieve
pressure, and turn the bottom lock collar
down the shaft.
2.
Allow the counterweight to slide down the
shaft, and finger tighten the top lock collar
against the counterweight.
UP
1. Turn the top lock collar up the shaft.
2. Push the counterweight up against the top
lock collar, and turn the bottom lock collar up
the shaft and against the counterweight.
The stop collar ( Figure 24 ) limits the amount
that the bending leaf can travel during bending,
thereby allowing you to repeat a bend at an exact
angle.

stop hub on stop rod.

To use the stop collar:
1.
Completely loosen the stop collar.
2.
Make the bend that you want to repeat and
hold the bending leaf in place at the top of
the bend.
3.
Slide the stop collar up against the stop hub
and tighten it in place, as shown in Figure
24
.
4.
Check the stop collar by lowering the bend-
ing leaf and then raising the bending leaf into
a bend. If the stop is working correctly, the
bending leaf will stop in the same position as
the first bend.
