Operating Instructions - RIDGID K-750 Manual

12. Securely install tool on the end of the cable (See
Figure 4) . If the connection is not secure, the cutting
tool may fall off in use.
13. Position the foot switch for easy accessibility. You
must be able to hold and control the cable, control the
foot switch, and reach the FOR/OFF/REV switch.
14. Confirm that the FOR/OFF/REV switch is in the OFF
position.
15. Run the cord along the clear path. With dry hands
plug the drain cleaner into a properly grounded outlet.
Keep all connections dry and off the ground. If the
power cord is not long enough, use an extension
cord that:
• Is in good condition.
• Has a three prong plug similar to that supplied on
the drain cleaner.
• Is rated for outdoor use and contains a W or W-A in
the cord designation (i.e. SOW), or complies with
H05VV-F, H05RN-F types or IEC type design
(60227 IEC 53, 60245 IEC 57).
• Has sufficient wire size (16 AWG (1.5mm
(15.2m) or less, 14 AWG (2.5mm
(15.2m – 30.5m) long). Undersized wires can over-
heat, melting the insulation or causing a fire or other
damage.
When using an extension cord, the GFCI on the
drain cleaner does not protect the extension cord. If
the outlet is not GFCI protected, it is advisable to
use a plug in type GFCI between the outlet and the
extension cord to reduce the risk of shock if there is a
fault in the extension cord.

Operating Instructions

WARNING
Always wear eye protection to protect your eyes
against dirt and other foreign objects.
Only wear RIDGID drain cleaning gloves or mitts.
Never grasp the rotating cable with anything else, in-
cluding a glove or a rag. They can become wrapped
around the cable, causing serious injury.
When cleaning drains that might contain hazardous
chemicals or bacteria, wear appropriate protective
equipment, such as goggles, face shields or respi-
rators, to prevent burns and infections. 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.
Follow operating instructions to reduce the risk of
injury from twisted or broken cables, cable ends
whipping around, machine tipping, chemical burns,
infections and other causes.

1. Make sure that machine and work area is properly set
up and that the work area is free of bystanders and
other distractions.
2. Pull cable out of drum and feed into drain. If needed,
loosen AUTOFEED knob. Push cable as far into drain
as it will go. At least one foot (.3 m) of cable must be
in drain so that the end of the cable will not come out
of the drain and whip around when the machine is
started.
Directly route the cable from the outlet of the machine
to the drain opening, minimizing exposed cable and
changes in direction. Do not tightly bend the cable –
this can increase the risk of twisting or breaking.

3. Assume a proper operating position:
• Be sure you can control the ON/OFF action of the
foot switch and can quickly release the foot switch
if needed. Do not press foot switch yet.
• Be sure that you have good balance, do not have to
over reach, and cannot fall on the foot switch, drain
cleaning machine, the drain or other hazards.
