end of the cable from the drain while the cable is rotating.
The cable can whip around and cause serious injury.
Pay attention to the cable during retrieval as the cable end
can still become stuck.
Place the FOR/OFF/REV switch in the 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.

Using Machine With A Front Guide Hose

The front guide hose is an optional accessory to help
protect fixtures and contain the liquid and debris thrown
off of the cable. It can only be used with an AUTOFEED.
Using the Front Guide hose can decrease feedback
from the cable, making it harder to tell what conditions
the cable is encountering. This may increase the pos-
sibility of damage to the cable. Using the front guide
hose makes it more difficult to switch back a forth be-
tween manual and AUTOFEED operation.
Using a machine with the front guide hose is similar to
using a machine with just the AUTOFEED. Follow in-
structions for AUTOFEED operation with the following
exceptions:
• When setting up the machine, insert the guide hose at
least 6" into the drain.
Figure 15 – Using Machine with Guide Hose
• Instead of holding the cable, hold the guide hose. See
Figure 15. Always control the guide hose and properly

support the cable to prevent the cable from twisting,
kinking or breaking.
When using a front guide hose, pay attention how the
guide hose feels in your hand and watch the drum ro-
tation. Because the guide hose is over the cable, there
is less sensitivity to the loading of the cable, and it is
harder to tell if the tool is rotating or not. If the tool is not
rotating, the drain is not being cleaned.
If the tool continues to get hung up in the blockage,
stop using the AUTOFEED (leave the feed lever in the
neutral position) and work the cable manually. To do this,
the cable must be retrieved from the drain and the guide
hose removed to allow proper positioning of the machine
to the drain and access to the cable. Do not try to work the
cable by hand with the front guide hose in place.
When retrieving the cable, be sure to stop the cable
before the tool is pulled into the end of the guide hose to
prevent damage.

Adding Additional Cable

If more cable is necessary to clean the drain than is avail-
able in the machine drum, use the following procedures to
add additional cable.
1. Make sure that the FOR/OFF/REV switch is in the
OFF position and the machine is unplugged.
2. Pull the cable connection from the drum. If using the
AUTOFEED, the feed knob may need to be loos-
ened.
3. Disconnect the cable from the pigtail and secure the
cable so it cannot slip down the drain.
4. If loading another cable in the existing drum, see
"Installing Cable" in the Assembly section.
5. Make sure that the drain cleaning machine is properly
set up. Attach the end of the cable in the drain to the
cable in the drum. Feed any excess cable back into
the drum.
6. Resume cleaning the drain. Make sure that the cable
is rotating and up to speed before feeding cable in.

Drum Removal and Installation

1. Make sure that the FOR/OFF/REV switch is in the
OFF position and the machine is unplugged.
2. If needed, remove AUTOFEED from machine by un-
screwing mounting bolt with
AUTOFEED will come off as one. See Figure 16.
