4. The optic gauge zero mark must be aligned with the mark on the
top frame.
5. Start hydraulic pump. Press ADVANCE button on pump control
pendent until bend is complete.
Releasing Conduit
1. To remove conduit from bender, press RETRACT button on
pendant until pressure is off conduit. Release button.
2. Remove left side pivot pin and pivot assembly. Place pivot pin in
pipe eject hole (which is marked for conduit size). Pin must be
through bottom frame.
3. Press RETRACT button until cylinder plunger is fully retracted.
Remove conduit from bender.
Maximum Conduit Sizes
The “Poly Bender” shoes are manufactured to bend PVC coated rigid
conduit with a coating thickness of 40 mil. Given tolerances on coating
thickness and normal conduit tolerances, the bender shoes are capable
of bending the following maximum diameters of PVC coated conduit.
If measured conduit diameter is greater than the maximum allowable
diameter, do not attempt to bend that conduit. Attempting to bend
oversize conduit could cause damage to bender and will result in an
unacceptable bend. PVC coated conduit will expand when exposed to
direct sunlight and warm temperatures, and may exceed the maximum
diameter. Always measure conduit prior to bending.
