Figure 8 – Proper Operating Position
1. Manually pull a sufficient length of cable out of the
drum to start the tool and cable into the sewer inlet.
2. Move FOR/OFF/REV switch into FOR (forward) posi-
tion. Do not step on the air foot switch pedal at this
time.
3. Pull 18" – 24" cable from the machine – enough to
form a slight loop – and apply slightly downward
pressure with both hands on the cable. Do not force
the cable. Allow it to feed itself into the drain.
WARNING
Before starting machine, both operator's gloved
hands must be on cable.
4. Exert sufficient downward pressure on cable to keep
it in sewer line while depressing air foot switch pedal
to start cable rotating.
5. Pull cable out of drum and allow cable to feed itself
into the line. Always keep hand on the cable to feel the
tension.
6. Continue to feed the cable into the line until resistance
or obstruction is encountered. The condition will gen-
erally become apparent to the operator as the cable
will have a tendency to twist sideways in the opera-
tor's hands.
7. Pull back sharply on the cable to free the cutter and
relieve the load on the cable. Slowly advance cable
back into the obstruction. Repeat this process until the
obstruction is clear. Remember, make sure the cutter
is rotating at all times and never force the cable. If
motor turns but the drum stops, the torque limiter is
slipping because of excessive force. Pull back on
cable to relieve torque and drum will begin to spin.

WARNING
Do not allow tension to build up in the cable. This
will happen if the cutting tool hits a snag and
stops turning, but the motor and its drum continue
to rotate. Torque builds until the cable suddenly
twists, potentially wrapping around your hand or
arm. This can happen quickly and without warning,
so proceed slowly and carefully as you feed the
cable into the drain. If tool gets hung up in an
obstruction, refer to Reverse Operating Instructions
in the "Special Procedures" section.
8. Several passes through thoroughly blocked drain
lines are recommended. After establishing drain flow,
increase cutter size to thoroughly clean the lines.
9. Push cable into the drum with machine in FOR (for-
ward). The machine should be kept running during the
process for thorough cleaning and uniform re-setting
of cable in the drum.
NOTE! A continuous flush of water should be used to
clean the cable and tool as they are retrieved.
10. When the tool is just inside the sewer inlet, release the
air foot switch pedal and allow the machine to come to
a complete stop.
Never retract tool from sewer inlet while
WARNING
cable is rotating. Tool can whip causing serious injury.
11. Turn FOR/OFF/REV switch to OFF position and
remove cord from power source.
12. Pull the remaining cable and tool from the sewer.
Hand feed the cable into the machine.
13. Disengage the kickstands by tilting the machine for-
ward.

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 too far into main sewer or septic tank can allow
cables to knot-up and prevent their return.

Reverse Operation

Running machine in reverse will cause premature failure
of cable. Use reverse only to free a tool caught in an
obstruction. If this should occur, immediately remove
foot from air foot switch pedal and allow machine to
come to a full and complete stop. Place FOR/OFF/REV
switch to REV (reverse) position. If machine has auto-
matic feed, loosen feed knob. Grasp cable with gloved
hands and pull while jogging air foot switch pedal. When
tool is dislodged and drum has stopped rotating, place
