Setup
1. Parkthebenderonaat,rmsurface,suchas
a concrete oor. Do not set up the bender on a
inclined surface.
2. Insert a 5 ft (153 cm) length of 1" rigid conduit into
the lever unit (11) to serve as the bending handle.
Operation
1. Raise the handle completely to release the ratchet
mechanism.Manuallyrotatetheshoefullycounter-
clockwise.Lowerthehandle.
2. Slidetheconduittobebentoverthepipesupport

thehandledown.Repeatuntilthebendiscomplete.
Note: The bender degree indicator will not compen-
sate for springback.
