8. If cable loads down in the obstruction, relieve load by
pulling back on cable with short, quick jerks to free
cutter. 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. At this point, pro-
gress depends upon the sharpness of the tool and
nature of the obstruction.
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 cable 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. Releasing clutch handle will stop the cable ro-
tating and releases the torque. If tool gets hung up
in an obstruction, refer to Reverse Operating
Instructions in the "Special Procedures" section.
9. Once obstruction is cleared, it is recommended that
operator flush debris from line with running water.
Repeat Step 8 several times if necessary for thorough
cleaning job and then work cable through additional
stoppages as required.
10. To add cable, the following procedure should be fol-
lowed:
• After reaching the end of each cable section, turn
the machine OFF.
• Secure the cable by looping it in the line (Figure 7).
This procedure is especially useful when cleaning
a line with a steep grade.
Figure 7 – Looping Cable In Line
• With line secured, insert another section of cable
in through the front of the machine (female end
first) until approximately one foot remains out the
front of the machine.
• Attach cable to cable in line and resume operation.
11. To retrieve cable from drain line, the following proce-
dure should be followed:
• Leave FOR/OFF/REV switch in FOR (forward) po-
sition.

• Push down on clutch handle to engage cable.
With mitted hand pull cable out of line (if possible)
or hold cable against edge of inlet to thread the
cable out until loop forms in front of the machine.
NOTE! By holding the cable against the edge of the inlet,
the rotation will rapidly "thread" the cable out of the
line.
• When loop forms, release clutch handle and push
excess cable back through machine. Disconnect
one section at a time.
When disconnecting sections, remem-

ber to turn unit off and secure cable in line.
• Once section of cable is removed, insert the se-
cured cable in through the front of the machine and
continue removing sections until tool on last section
of cable is just inside sewer inlet.
HINT! When placing removed cables back into cable
carrier, reconnect all cables. This assures easy
removal at next job.
Never retract tool from sewer inlet while

cable is rotating. Tool can whip causing serious injury.
12. Turn FOR/OFF/REV Switch to OFF position.
13. Pull remaining cable and tool from sewer.
14. Unplug power cord and remove guide hose.
After using, thoroughly flush and drain ca-

effects of some drain cleaning compounds.
Special Procedures
Reverse Operation
Running machine in reverse will cause premature fail-
ure of cable. Use reverse only to free a tool or cable
caught in an obstruction. If this should occur, immedi-
ately release clutch handle and place FOR/OFF/REV
switch to OFF position. After motor comes to a complete
stop, place FOR/OFF/REV switch in the REV (reverse) di-
rection. Engage clutch handle only until cable or tool is free
of obstruction. Once it is free, release clutch handle im-
mediately. Turn unit OFF. Run unit in FOR (forward)
direction and follow normal operating procedure.
Never operate this machine in REV (re-
WARNING
verse) for any other purpose. Operating in reverse can
damage a cable and cause serious injury.
