Special Procedures
Main Sewer Or Septic Tank Overrun
It is very important to know the approximate distance from
inlet to main sewer or septic tank. Over-running cable
into main sewer or septic tank can cause cables to knot-up
and prevent their return through small lines.
Starting Cable Through P-Trap
A trap leader is recommended. Trap leaders are flexible
2' lengths of cable connected to the front end of cable.
Manual operation is recommended. Before starting ma-
chine, position cutter in bottom of trap (NOTE: Special
P-Trap Cutters are recommended), and pull enough
cable from machine to form a loop between machine and
drain opening. Push down sharply on the bend in cable.
A light tap in the foot pedal or hand turning the drum will
reposition the blade to allow easier passage through
the trap. Operator may choose to use powerfeed after ne-
gotiating trap.
Adding Additional Cable – Powerfeed
Machines
To run a second cable down the drain/sewer line, the fol-
lowing procedure should be followed:
1. Stop power feed operation before cable-to-pigtail
connection reaches power feed rollers.
2. Loosen feed knob.
3. Grasp and pull cable until cable-to-pigtail connection
passes through power feed assembly.
NOTE! When running 5 /

4. Disconnect cable from pigtail. Make sure that it does
not slip down the drain/sewer inlet such that you can-
not reach it.
5. Stretch out additional cable and attach end of new
cable to pigtail and push cable-to-pigtail connection
back through power feed assembly. Tighten knob
and feed new cable into drum.
Remove empty drum assembly and mount new drum
assembly loaded with cable onto machine. (See Drum
Removal/Installation Procedure)
6. Attach front end of second cable to back end of cable
currently in the drain line and continue the feed op-
eration.
NOTE! Be sure entire cable and blade is rotating in
drain before feeding cable into drain.
NOTE! When you need to know how much cable you
have left in your drum, remember one wrap of
cable in your drum is approximately 4'.
Adding Additional Cable - Manual Feed

lowing procedure should be followed.
1. Grasp and pull cable until cable-to-pigtail connection
is accessible.

slip down the drain/sewer inlet such that you cannot
reach it.
3. Attach end of new cable to pigtail and feed new cable
into drum.
Remove empty drum assembly and mount new drum
assembly loaded with cable onto machine. (See Drum
Removal/Installation Procedure)

currently in the drain line and continue the feed op-
eration.
