K-750 Drain Cleaning Machine
• Clear path to transport the drain cleaner to the work
area.
2. Inspect the drain to be cleaned. If possible, deter-
mine the access point(s) to the drain, the size(s) and
length(s) of the drain, distance to tanks or mainlines,
the nature of the blockage, presence of drain cleaning
chemicals or other chemicals, etc. If chemicals are pre-
sent in the drain, it is important to understand the
specific safety measures required to work around
those chemicals. Contact the chemical manufacturer
for required information.
If needed, remove fixture (water closet, etc.) to allow
access to the drain. Do not feed the cable through a
fixture. This could damage the drain cleaner and the
fixture.
3. Determine the correct drain cleaning equipment for
the application. The K-750 drain cleaner is made
for:
• 3" to 6" lines up to 150' long with
• 4" to 8" lines up to 200' long with
Drain cleaners for other applications can be found
by consulting the the Ridge Tool Catalog, on line
at RIDGID.com or RIDGID.eu.
Inner-Core Cable is not recommended for use through
P-Traps and severe bends in lines smaller than 4".
Optional 24" flexible trap leaders can be added to aid
users through traps and tight clean-outs.
4. Make sure machine has been properly inspected.
5. If machine is equipped with an AUTOFEED, confirm
that the AUTOFEED is set to the proper size for the
cable being used (see Figure 9). The slots in the
ends of the pins should align with the size of cable
being used. A screwdriver can be used to turn the
pins. The AUTOFEED adjustment knob may need to
be loosened to allow the size to be adjusted.
6. If needed, place protective covers in the work area.
The drain cleaning process can be messy.

lifted, use proper lifting techniques. Use care moving
equipment up and down stairs, and be aware of pos-
sible slip hazards. Wear appropriate footwear to help
prevent slips.
cable outlet is within 3 feet of the drain access. Great -
er distances from the drain access increases the risk
of the cable twisting or kinking. If the machine cannot
be placed with the cable outlet within 3' of the drain ac-
cess, extend the drain access back to within 3' of
the cable outlet with similar sized pipe and fittings.
Improper cable support can allow the cable to kink and
twist and can damage the cable or injure the operator.
See Figure 10. If using front guide hose, place ma-
chine so that at least 6" of guide hose can be placed
in drain opening.
