4. Continue to feed the cable into the line until resistance
or obstruction is encountered. This will become ap-
parent to operator as it will be difficult to feed additional
cable into line and/or the cable will have a tendency to
twist sideways in operator's hands.
5. If cable loads down in the obstruction, relieve load by
pulling back on cable with short, quick jerks to free cut-
ter. 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 be-
cause of excessive force.
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 ro-
tate. 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.
6. Once obstruction is cleared, it is recommended to
flush debris from line with running water. Repeat
Step 5 several times if necessary for a thorough
cleaning job. Work cable through additional stop-
pages as required. After establishing flow, increase
cutter size to thoroughly clean line.
7. To retrieve cable from drain line, run machine in
FORWARD direction. Pull one to two feet of cable
from sewer and manually push back into the ma-
chine. This procedure should be continued until it is
apparent that the tool is just inside sewer inlet.
Never retract tool from sewer inlet while
WARNING
cable is rotating. Tool can whip causing serious injury.
NOTE! It is recommended that a continuous flush of
water be used to clean the cable and tool as
they are retrieved.
8. Turn FOR/OFF/REV Switch to OFF position and re-
move cord from power source.
9. Pull remaining cable and tool from sewer and hand
feed cable back into machine.
Using Autofeed Machines
1. Manually pull sufficient cable out of the drum to start
tool and cable into the sewer inlet. Push cable into inlet
as far as it will go.
2. Move FOR/OFF/REV switch into FOR (forward) po-
8
sition. Do not step on the air foot switch pedal at this
time.
3. Loosely grasp cable with gloved hand and place other
hand on the feed lever. Feed lever should be in the
neutral position (vertical or 12 o'clock). Exert sufficient
downward pressure on cable to maintain control while
depressing foot actuator to start drum rotation. Do
not force the cable. Allow it to feed itself into the drain.
Before starting machine, operator's gloved hand
must be on the cable.
4. To automatically feed cable into line, move feed lever
in same direction as rotating drum and cable (Figure
7) . Push feed lever away from neutral (vertical) posi-
tion until it engages and feeds the cable. Full advance
or retrieval is almost 90° from the neutral position.
Always keep hand on the cable to feel tension.

5. 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.
6. Operator should immediately respond to this condition
by moving feed lever into full reverse (opposite direc-
tion of drum rotation). This should release the twist in
cable and reduce size of cable loop.
