K-380 Drain Cleaning Machine
7. Once free of this obstruction and the load is relieved
from the cable, gradually feed cable forward. Remem-
ber, when using the feed mechanism the rate of cable
advance is controlled by the autofeed handle. Allow
cutter to advance slowly and work through the obstruc-
tion. If cable shows signs of loading (generally apparent
by growing loop between machine and drain), imme-
diately back cutter from obstruction by reversing feed.
NOTE! At this point, progress depends upon the sharp-
ness of the tool and the nature of the obstruction.
Continued operation should be in manual feed
mode until the obstruction has been cleared.
8. Manually pull back sharply on the cable to free the cut-
ter 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 lim-
iter is slipping because 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 pro-
ceed 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.
9. Several passes at a thoroughly blocked drain line
are recommended. After establishing flow, increase
cutter size to thoroughly clean line. Flush with strong
flow of water.
10. To retrieve cable from sewer line, move the feed
lever in opposite direction of drum rotation (Figure 8) .
The cable should now feed itself back into machine.
The retrieval process is greatly aided by manually
pulling the cable from the drain a foot at a time as the
autofeed is used.
Figure 8 – Autofeed in Reverse Position
NOTE! It is recommended that a continuous flush of
water be used to clean cable and tool as they
are retrieved.
11. 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.
WARNING
cable is rotating. Tool can whip causing serious injury.
12. Turn FOR/OFF/REV switch to OFF position and re-
move cord from power source.
13. Pull remaining cable and tool from the sewer. Hand
feed the cable into the machine.
Special Procedures
Reverse Operation
Running machine in reverse will cause premature failure
of cable. Use reverse only to free a tool caught in an ob-
struction. 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.
Tighten screw on nose of machine so that it firmly captures
cable to avoid kinks occurring inside the drum. If ma-
chine has automatic feed, move feed knob to neutral
position. Grasp cable with gloved hands and pull while jog-
ging air foot switch pedal. When tool is dislodged and
drum has stopped rotating, place FOR/OFF/REV switch in
FOR (forward) position, loosen set screw on nose of ma-
chine and follow normal operating procedure.
WARNING
verse) for any other purpose. Operating in reverse can
damage a cable and cause serious injury.

Installing Replacement Cable

FOR/OFF/REV switch should be OFF and machine
unplugged before removing or installing cable.

To Remove Damaged or Worn Cable

1. Pull out excess cable from drum allowing access to
cable bracket.
2. Loosen screw on back of drum that fastens cable
bracket clamping cable against back wall of drum.
3. Pull end of old cable from drum and discard.
