Machine And Work Area Set-Up - RIDGID K-750 Manual

Make sure the cable is fully retracted with no more
than 6" of cable outside of the machine. This will
prevent whipping of the cable at start up.
7. Inspect the tools for wear and damage. If necessary,
replace prior to using the drain cleaning machine.
Dull or damaged cutting tools can lead to binding,
cable breakage, and slow the drain cleaning process.
8. Make sure that the FOR/OFF/REV switch is set to the
OFF position.
9. With dry hands, plug cord into properly grounded out-
let. Test the GFCI provided in the electrical cord to in-
sure that it is operating correctly. When the test button
is pushed in, the indicator light should go off. Reacti-
vate by pushing the reset button in. If the indicator light
goes on, the GFCI is functioning properly. If GFCI is
not functioning properly, unplug the cord and do not
use the drain cleaning machine until the GFCI has
been repaired.

10. Move the FOR/OFF/REV switch into the FOR position.
Press the foot switch and note the direction of rotation
of the drum. If the foot switch does not control the ma-
chine 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 shown 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, twist-
ed or broken cables, chemical burns, infections 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 op-
erator. 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.
• 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.
