cable with gloved hands. Do not allow the cable to build up
outside the drain, bow or curve. This can allow the cable
to twist, kink or break.
When the cable has been fed into the drain opening,
pull 6"-12" more cable from the drum and continue feed-
ing the rotating cable into the drain.
AUTOFEED Operation
Confirm that at least one foot (.3 m) of cable is in the drain.
Tighten the AUTOFEED knob (Figure13) so that the
roller touches the cable plus one additional turn. Do no
overtighten the knob – this can cause premature failure of
the AUTO FEED or cable.
Grasp near the center of the exposed length of cable with
a gloved hand. Gloved hand must be on the cable to con-
trol and support the cable. Improper cable support can
allow the cable to kink or twist and can damage the
cable or injure the operator. Make sure that the cable out-
let of the drain cleaner is within 3' of the drain opening.
Place the other hand on the AUTOFEED lever. AUT-
OFEED lever should be in neutral (Vertical) position (see
Figure 13).
See "Using Machine With A Front Guide Hose" if using
a guide hose.

NOTE: Rate of cable advance or retrieve varies by
handle movement from neutral.
Depress the foot switch to start the machine. The person
controlling the cable must also control the foot switch. Do
not operate the drain cleaner with one person controlling
the cable and another person controlling the foot switch.

This can lead to twisting, kinking and breaking of the
cable. With the cable rotating, move the AUTOFEED
control handle in the same direction that the cable rotates.
This will cause the cable to feed out of the machine. The
further the control handle from the neutral position, the
faster the cable will be fed (up to 20' per minute, maxi-
mum). The rotating cable will work into the drain as you
control the cable with your gloved hand. Do not allow
the cable to build up outside the drain, bow or curve.
This can allow the cable to twist, kink or break.

Cleaning The Drain

As you feed the cable into the drain, you may see the

• Sharp thrusts of the cable, both with and without the
cable rotating, can help the cable through a trap.
• In some cases with the switch in the OFF position,
rotating the drum by hand can change the orien-
tation of the cutter to allow it to more easily ne-
gotiate the fitting.
• Run the drain cleaner in REV (REVERSE) rotation
for several seconds while pushing on the cable.
Only do this long enough to get the cable started
through the trap. Running the cable in reverse can
damage the cable.
• Use a flexible leader between the tool and the
cable.
• If these options don't work, consider using a smaller
diameter or more flexible cable, or a different drain
cleaner.
