10. Move the FOR/OFF/REV switch into the FOR posi-
tion. Press the foot switch and note the direction of ro-
tation of the drum. If the foot switch does not control
the machine operation, do not use the machine until
the foot switch has been repaired. The drum should
rotate counter-clockwise when viewed from the front
of the drum, and will match the drum direction s hown
on the warning label (Figure 7) and shown in Figure 8.
Release the foot switch and let the drum come to a
complete stop. Place the FOR/OFF/REV switch into
the REV position, and repeat above testing to confirm
that the drain cleaner operates properly in reverse. If
the rotation is not correct, do not use the machine until
it has been repaired.
11. With the inspection complete, move the FOR/OFF/ -
REV switch into the OFF position and, with dry hands,
unplug the machine.

Machine and Work Area Set-Up

WARNING
Set up the drain cleaning machine and work area ac-
cording to these procedures to reduce the risk of in-
jury from electric shock, fire, machine tipping,
twisted or broken cables, chemical burns, infec-
tions and other causes, and prevent drain cleaner
damage.
Always wear safety glasses, RIDGID drain cleaning
gloves, and other appropriate protective equipment
when setting up your drain cleaner. For extra pro-
tection from chemicals and bacteria on the ma-
chine and in the work area, wear latex, rubber or
other liquid barrier gloves under the RIDGID drain
cleaning gloves. Rubber soled, non-slip shoes can
help prevent slipping and electric shock, especially
on wet surfaces.
1. Check work area for:
• Adequate lighting.
• Flammable liquids, vapors or dust that may ignite. If
present, do not work in area until sources have
been identified and corrected. The drain cleaner is
not explosion proof and can cause sparks.
• Clear, level, stable dry place for machine and oper-
ator. Do not use the machine while standing in wa -
ter. If needed, remove the water from the work area.
Wood or other coverings may need to be put down.
K-750 Drain Cleaning Machine
• Properly grounded electrical outlet. A three-prong or
GFCI outlet may not be properly grounded. If in
doubt, have outlet inspected by a licensed electri-
cian.
• Clear path to electrical outlet that does not contain
any potential sources of damage for the power
cord.
• 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 www.RIDGID.com or www.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.
