PROBABLE CAUSE
Roller support is not all the way
down.
Unloaded to the starting position.
Too much squeeze on 1-1/2" or 2"
EMT, IMC, or rigid aluminum conduit.
Shoe rotated too far in unload
direction.
Roller support is not all the way
down.
Power was turned off while bending
1-1/2" or 2" EMT, IMC, or rigid
aluminum conduit.
Roller support lockout switch or wire
harness is bad or poorly adjusted.
Roller support is locked or jammed.
Due to the geometry of the bend, the
shoe hook would end up interfering
with the first bend while making the
second.
The first mark must be at least one
pipe diameter away from the end of
the conduit to prevent damage to the
conduit.
