RIDGID K-750 Operating Instructions Manual page 5

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 neu-
tral 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 be-
fore 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
available in the machine drum, use the following pro-
cedures 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.
