flip over outside the drum. If the drum stops turning, the
cable and tool also are not turning.

Freeing A Stuck Tool

If the tool is stuck in the blockage, with the FOR/O-OFF/-
REV switch in the O-OFF position and the foot switch re-
leased, try pulling the cable loose from the blockage. If the
tool will not come free from the blockage, place the FOR/O-
OFF/REV switch in the REV position. Grasp the cable
with both gloved hands, press the foot switch for several
seconds and pull on the cable until it is free of the blockage.
Do not operate the machine in the REV position any longer
than required to free the cutting tool from the blockage or
cable damage can occur. Place the FOR/O-OFF/REV
switch in the FOR position and continue cleaning the drain.

Retrieving The Cable

Once the drain is open, start a flow of water down the
drain to flush the debris out of the line. This can be
done by running a hose down the drain opening, turning
on a faucet in the system or other methods. Pay attention
to the water level, as the drain could plug again.
Figure 13 – (1) Pulling Cable and (2) Feeding into the Drum
With water flowing through the drain, retrieve the cable
from the line. The flow of water will help to clean the
cable as it is retrieved. The FOR/O-OFF/REV switch
should be in the FOR position – do not retrieve the cable
with the switch in the REV position, this can damage the
cable. As with feeding the cable into the drain, cables can
be caught while being retrieved.
With both gloved hands equally spaced on the exposed
12
cable for control, pull 6"-12" lengths of cable from the
drain at a time and feed it into the drum (Figure 13).
Continue retrieving cable until the cable end is just inside
the drain opening. Release the foot switch and allow the
machine to come to a complete stop. Do not pull the
end of the cable from the drain while the cable is rotating.
The cable can whip around and cause serious injury.
Place the FOR/O-OFF/REV switch in the O-OFF position.
Pull the remaining cable from the drain with gloved hands
and feed back into the drain cleaner. If needed, change
the tool and continue cleaning following the above pro-
cess. Several passes through a line are recommended for
complete cleaning.
With dry hands unplug the machine.

Draining Drum

If the machine needs to be drained, turn machine OFF,
and with dry hands, unplug the machine. Tip the machine
forward to drain the drum and rotate the drum to allow it
to drain completely.
Figure 14 – Preparing For Transport

Preparing For Transport

Remove any tool from the cable. Feed cable into the
drum, leaving no more than 6" (15 cm) exposed. Wrap
cord and foot switch around the handle. One transport
method shown in Figure 14. If the machine needs to be
lifted, use proper lifting techniques. Use care moving
equipment up and down stairs, and be aware of possible
slip hazards.
