SQUEEZE ADJUSTMENT PROCEDURE FOR
1 1/2" AND 2" EMT & IMC ROLLER SUPPORTS
The 1 1/2" and 2" rollers on the single shoe EMT Roller Support and the 1 1/2"
and 2" rollers on the single shoe IMC Roller Support on the 77 bender have a
Squeeze Adjustment feature if wrinkling or side marking becomes a problem
during the bending process. This feature allows you to increase or decrease
the amount of pressure applied to the conduit during bending, thereby elimi-
nating these problems. Begin with the 7/8" starting location of the adjusting
bolts as shown in Figure 17a.
1. If wrinkling occurs, pressure against the conduit during the bending process
must increase. To increase the squeeze ( pressure ), loosen both set screws
and turn both adjusting bolts one-half turn clockwise. Bend one piece of
conduit to test the adjustment, and if wrinkling still occurs, repeat the
procedure. Once you have achieved a good bend, tighten both set screws.
NOTE: Both adjusting bolts MUST be in contact with the bender leg.
See Figure 17a.
2. If side marking occurs, pressure against the conduit during the bending
process must be decreased. To decrease the squeeze ( pressure ), loosen
both set screws and turn both adjusting bolts one-half turn counter-clock
wise. Bend one piece of conduit to test the adjustment, if side marking
still occurs, repeat the procedure. Once you have achieved a good bend,
tighten both set screws.
NOTE: Both adjusting bolts MUST be in contact with the bender leg. See
Figure 17a.
