all times and never force the cable. At this point,
pro gress depends upon the sharpness of the tool
and nature of the obstruction.
Do not allow tension to build up in the cable. This will
happen if the cutting tool hits a snag and stops turn-
ing, but the motor and cable continue to rotate.
Torque builds until the cable suddenly twists, po-
tentially 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. Releasing clutch handle will stop the
cable rotating 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 that has rapid fall, such as working from a
stack line.
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, in the FOR (FORWARD) position, the ro-
tation 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-
WARNING
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.
WARNING 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.
After using, thoroughly flush and drain

cables, couplings and tools with water due to damaging
effects of some drain cleaning compounds.
Cleaning Drain Using
Adapter
1. Assume the correct operating posture in order to
maintain proper balance (Figure 6).
Should an unexpected situation arise,
WARNING
this posture provides you with the opportunity to safely
keep control of the machine and cable.
• Be sure you can quickly release the clutch handle.
• Hand must be on the cable to control its twisting
action when it hits an obstruction.
• Must have access to FOR/OFF/REVERSE switch.
2. Pull out enough cable by hand to insert into the drain
opening and hand-feed the cable into drain until it
stops feeding easily. Push cable down drain line
keeping your control hand close to the drain opening.
3. Hold cable loosely in mittened hand, put FOR/OFF/
REV SWITCH in FOR (forward) position.
NOTE! The motor will start but cable will not rotate.
4. With mitted hand on cable, push down on clutch
handle with opposite hand to engage adapter.
5. Continue hand-feeding the cable slowly until the drain
is opened or blockage is encountered.
Keep your cable hand close to the drain
WARNING
opening to keep control of the cable and help prevent
cable flip-over.
6. When you reach the blockage, work the cable back
