OPERATION
1. Before stepping on the foot pedal, place the
guide tube and cable into the drain opening.
2. Tighten the knob at top of the Power Cable
Feed so that the feed roller presses against the
cable. Be sure not to over tighten since this
could cause excess cable wear.
3. The feed lever controls the feeding rate and
direction of the cable. Move the lever down to
feed cable out of drum.
The further the lever
is moved downward,
the faster the cable will
feed out. Move lever
up to retract cable into
drum. When the lever is
in the middle (neutral)
position, cable will spin
in place.
4. Move the motor switch to the forward posi-
tion.
5. With a gloved hand on the Guide Tube, de-
press the air foot pedal to start machine. Feed
the cable into the line and against the obstruc-
tion with a firm, even pressure. Adjust the feed-
ing rate to the resistance met. Do not force the
cable, let the cutter do the work. The job won't
go any faster and you could damage the cable
and injure yourself.
6. Don't allow slack in the cable between the
machine and the drain opening. If the cable
starts to buck or build up too much twist, stop
by taking your foot off of the pedal. Move the
feed lever to reverse and step on the pedal to
retract excess cable back into the cable. Then
move the feed lever to forward and continue
feeding at a slower rate.
7. If you're having trouble getting around tight
bends, try putting the machine in reverse while
applying steady pressure.
MOTOR SWITCH
Forward • Off • Reverse
Don't do this for more than a few seconds at a
time since this could cause tangling in the drum
or kinking.
8. If you still can't get around the bend, you're
probably using too large a cable. Switch to a
5/8" or 1/2" diameter cable.

9. When the cable reaches the stoppage, allow
the cable to progress forward slowly, chewing
into the stoppage as it goes. This slow forward
movement will reduce stress on the cable while
doing a more thorough cleaning job. A back
and forth action often works best.
HINT: It's often helpful to have a small stream
of water running in the line to wash the cut-
tings away while the machine is in operation
and after.
10. Be careful not to let the cutter get caught
in the stoppage as you work through it. This
can cause kinking and breaking of the cable.
When you feel the cable starting to twist in your
hands, stop the machine and retract the cable.
This will free the cutter from the obstruction.
Then allow the cable to move forward slowly
into the stoppage. Remember, no cutting takes
place when the blades stop turning.
11. After the line has been opened, retract the
cable by moving the feed lever up. Make sure
the motor switch is in the forward position.
12. When you hear the end of the cable near the
drain opening, take your foot off of the pedal
to stop drum rotation. Never retract the cutter
from the drain opening while the cable is rotat-
ing. The cable could whip and cause serious in-
jury. Do not retract cutter into the Guide Tube.
IMPORTANT: DO NOT USE REVERSE TO PULL
THE CABLE OUT OF THE DRAIN. RUNNING MA-
CHINE IN REVERSE CAN CAUSE THE CABLE TO
TANGLE IN THE DRUM.
SPECIAL OPERATIONS
IF CABLE GETS CAUGHT IN LINE
The motor can be reversed to free the cable if it
gets caught in line.
(Note: if using Power Cable Feed, putting mo-
tor in reverse will cause the feed control lever to
operate opposite of normal.)
1. Move motor switch to the reverse position.
2. Step on the foot pedal while pulling on the
cable.
3. After cable is loose, move motor switch back
into forward position.
IMPORTANT: DO NOT RUN MOTOR IN RE-
VERSE FOR MORE THAN A FEW SECONDS AT A
TIME SINCE THIS COULD CAUSE THE CABLE TO
KINK OR TANGLE IN THE DRUM.
IF CABLE TANGLES IN DRUM
This is caused by using too much pressure when
feeding the cable or feeding the cable into the
line while running the machine in reverse. To
untangle the cable, rotate the drum in opposite
