General Safety Information
WARNING! Read and understand all instructions. Failure
to follow all instructions listed below may
result in electric shock, fire, and/or serious
personal injury.
SAVE THESE INSTRUCTIONS!
Work Area Safety
•Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
•Do not operate tools in explosive atmospheres,
such as in the presence of flammable liquids, gas-
es, or dust. Tools create sparks which may ignite the
dust or fumes.
•Keep bystanders, children, and visitors away while
operating a tool. Distractions can cause you to lose
control.
Electrical Safety
•Grounded tools must be plugged into an outlet,
properly installed and grounded in accordance
with all codes and ordinances. Never remove the
grounding prong or modify the plug in any way.
Do not use any adapter plugs. Check with a qual-
ified electrician if you are in doubt as to whether
the outlet is properly grounded. If the tools should
electrically malfunction or break down, grounding pro-
vides a low resistance path to carry electricity away
from the user.
•Avoid body contact with grounded surfaces such
as pipes, radiators, ranges and refrigerators. There
is an increased risk of electrical shock if your body is
grounded.
•Don’t expose electrical tools to rain or wet condi-
tions. Water entering a power tool will increase the
risk of electrical shock.
•Do not abuse cord. Never use the cord to carry the
tools or pull the plug from an outlet. Keep cord
away from heat, oil, sharp edges or moving parts.
Replace damaged cords immediately. Damaged
cords increase the risk of electrical shock.
•When operating a tool outside, use an outdoor ex-
tension cord marked “W-A” or “W”. These cords are
rated for outdoor use and reduce the risk of electrical
shock.
•Use only three-wire extension cords which have
three-prong grounding plugs and three-pole re-
ceptacles which accept the machine’s plug. Use of
other extension cords will not ground the tool and in-
crease the risk of electrical shock.
•Use proper extension cords. (See chart.) Insufficient
conductor size will cause excessive voltage drop and
loss of power.
•Before using, test the Ground Fault Circuit Inter-
rupter (GFCI) provided with the power cord to
insure it is operating correctly. GFCI reduces the risk
of electrical shock.
•Extension cords are not recommended unless
they are plugged into a Ground Fault Circuit Inter-
rupter (GFCI) found in circuit boxes or receptacles.
The GFCI on the machine power cord will not pre-
vent electrical shock from the extension cords.
•Keep all electrical connections dry and off the
ground. Do not touch plug with wet hands. Reduces
the risk of electrical shock.
Personal Safety
•Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not
use tool while tired or under the influence of drugs,
alcohol, or medications. A moment of inattention
while operating power tools may result in serious per-
sonal injury.
•Dress properly. Do not wear loose clothing or
jewelry. Contain long hair. Keep your hair and
clothing away from moving parts. Loose clothes,
jewelry, or long hair can be caught in moving parts.
•Avoid accidental starting. Be sure switch is OFF be-
fore plugging in. Carrying tools with your finger on the
switch or plugging tools in that have the switch ON in-
vites accidents.

•Remove adjusting keys or wrenches before turning
the tool ON. A wrench or a key that is left attached to
a rotating part of the tool may result in personal injury.
•Do not over-reach. Keep proper footing and bal-
ance at all times. Proper footing and balance enables
better control of the tool in unexpected situations.
•Use safety equipment. Always wear eye protec-
tion. Dust mask, non-skid safety shoes, hard hat, or
hearing protection must be used for appropriate con-
ditions.
Tool Use and Care
•Use clamp or other practical way to secure and
support the workpiece to a stable platform. Holding
the work by hand or against your body is unstable
and may lead to loss of control.
•Do not force tool. Use the correct tool for your
application. The correct tool will do the job better
and safer at the rate for which it is designed.
•Do not use tool if switch does not turn it ON or
OFF. Any tool that cannot be controlled with the switch
is dangerous and must be repaired.
•Disconnect the plug from the power source before
making any adjustments, changing accessories, or
storing the tool. Such preventive safety measures re-
duce the risk of starting the tool accidentally.
•Store idle tools out of the reach of children and
other untrained persons. Tools are dangerous in
the hands of untrained users.
•Maintain tools with care. Keep cutting tools sharp
and clean. Properly maintained tools with sharp cutting
edges are less likely to bind and are easier to control.
•Check for misalignment or binding of moving
parts, breakage of parts, and any other condition
that may affect the tool's operation. If damaged,
have the tool serviced before using. Many acci-
dents are caused by poorly maintained tools.
•Use only accessories that are recommended by the
manufacturer for your model. Accessories that may
be suitable for one tool may become hazardous when
used on another tool.
•Keep handles dry and clean; free from oil and
grease. Allows for better control of the tool.
Service
•Tool service must be performed only by qualified
repair personnel. Service or maintenance performed
by unqualified repair personnel could result in injury.

•When servicing a tool, use only identical replace-
ment parts. Follow instructions in the Maintenance
Section of this manual. Use of unauthorized parts or
failure to follow maintenance instructions may create a
risk of electrical shock or injury.
Specific Safety Information
WARNING
Read this Operator’s Manual carefully before using
the RIDGID®K-7500 Drain Cleaner. Failure to un-
derstand and follow the contents of this manual
may result of electrical shock, fire and/or severe per-
sonal injury.
Call the Ridge Tool Company, Technical Service Depart-
ment at [phone] if you have any questions.
Drain Cleaner Safety
•Wear gloves provided with the machine. Never
grasp a rotating cable with a rag or loose fitting
cloth glove. Could become wrapped around the cable
and cause serious injury.
•Do not overstress cables. Keep one hand on the
cable for control when the machine is running.
Overstressing cables because of obstruction may
cause twisting or kinking or breaking of the cable and
result in serious injury.
•Position machine within three feet of inlet. Use
Front Guide Hose or properly support exposed
cable when it is difficult to locate the machine near
the access or clean out. Greater distances can result
in cable twisting, kinking or control problems.
•The K-7500 is designed for one-person operation.
Operator must control foot switch and cable.
•Use foot switch to operate K-7500 while main-
taining good footing and balance. Do not operate
machine in (REV) reverse. Operating machine in
reverse can result in cable damage and is used only
to briefly back tool out of an obstruction.
•Keep hands away from rotating drum and guide
tube. Do not reach into drum unless machine is un-
plugged. Hand may be caught in the moving parts
resulting in serious injury.
•Use kickstand during operation. The kickstand sta-
bilizes machine to prevent tipping.
•Be careful when cleaning drains where cleaning
compounds have been used. Avoid direct contact
with skin and eyes. Serious burns can result from
some drain cleaning compounds.
