7. Open tractor drive enough to feed the
duct rod through the pusher.
8. Place sub-duct from the manhole into
out-feed sub-duct clamp and tighten with
3/4” wrench (provided).
9. Take a 5’ piece (approx) of 1-1/4 sub-
duct and lay it into the opened infeed
sub-duct clamp. Feed the rod thru the
duct so that it’s about a foot into the
duct rodder, ensuring that the con-
nector on the end of the rod is past
the infeed clamp. Now tighten the
clamp on the duct.
10. Clamp the other end of the 1 1/4” sub-
duct into the supplied duct rodder car-
riage clamp.
TIP:
If the duct that is to be rodded is larger
than 1 1/4”, insert a piece of 1 1/4 sub-
duct from the out-feed of the Duct Rod-
der into the larger duct causing the
smaller duct to act like a feeder.
Tie off the small duct to a ladder or some
other permanent fixture if possible. This
prevents the sub-duct from kicking back
should the duct rod encounter and ob-
struction.
