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 power tools in explosive atmo-
spheres, such as in the presence of flammable
liquids, gases, or dust. Tools create sparks which
may ignite the dust or fumes.
•Keep bystanders, children, and visitors away while
operating a power 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 tool 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.
•Do not expose electrical tools to rain or wet con-
ditions. Water entering a 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
extension cord marked “W-A” or “W”. These cords
are rated for outdoor use and reduce the risk of elec-
trical shock.
•Use only three-wire extension cords which have
three-prong grounding plugs and three-pole recep-
tacles which accept the tool’s plug. Use of other
extension cords will not ground the tool and increase
the risk of electrical shock.
•Use proper extension cords.
(See chart.) Insufficient
conductor size will cause excessive voltage drop, 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
Interrupter (GFCI) found in circuit boxes or recep-
tacles. The GFCI on the machine power cord will not
prevent electrical shock from the extension cords.
•Keep all electrical connections dry and off the
ground. Do not touch plugs or tool 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, cloth-
ing, and gloves away from moving parts. Loose
clothes, jewelry, or long hair can be caught in moving
parts.
•Avoid accidental starting. Be sure switch is OFF
before plugging in. Carrying tools with your finger
on the switch or plugging tools in that have the switch
ON invites accidents.
•Remove adjusting keys or switches 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
conditions.
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
reduce 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 cut-
ting 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 condi-
tion that may affect the tool's operation. If dam-
aged, have the tool serviced before using. Many
accidents 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-
K-750R 5/8" Cage Machine
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.

Description, Specifications and
Standard Equipment
Description
The RIDGID K-750R Drain Cleaning Machine will clean
drain lines 3″to 6″in diameter and 100 feet in length. It
is specifically designed with a steel wire drum to allow for
inspection and cleaning of the cable.
The steel wire drum is belt-driven by a 1/2HP electric
motor that has a grounded electrical system. An integral
Ground Fault Interrupter (GFCI) is built into the line cord
and a “kickstand” base is provided for machine stability
during operation. A pneumatic foot actuator provides
ON/OFF control of the motor.
The drum powers a 5/8″inner core cable that has a quick
change coupling system for connecting or disconnecting
tools. The cable is manually fed in and out of the drain. An
integral torque limiter will cause the drum to stop rotating
whenever excessive torque is created when the cutting tool
attached to the cable hits a snag and stops rotating.

Machine Inspection
WARNING
To prevent serious injury, inspect your Drain
Cleaning Machine. The following inspection pro-
cedures should be performed before each use.
1. Make sure the Drain Cleaning Machine is unplugged
and the directional switch is set to the OFF position
(Figure 6) .
Figure 6 – K-750R Drain Cleaner
2. Make sure the foot switch is present and attached to
the Drain Cleaning Machine (Figure 6) . Do not oper-
ate the machine without a foot switch.
3. Inspect the power cord, Ground Fault Circuit Inter-
rupter (GFCI) and plug for damage. If the plug has
been modified, is missing the grounding prong or if the
cord is damaged, do not use the Drain Cleaning
Machine until the cord has been replaced.
4. Inspect the Drain Cleaning Machine for any broken,
missing, misaligned or binding parts as well as any
other conditions which may affect the safe and normal
operation of the machine. If any of these conditions are
present, do not use the Drain Cleaning Machine until
any problem has been repaired.
5. Lubricate the Drain Cleaning Machine, if necessary,
according to the Maintenance Instructions.
6. Use tools and accessories that are designed for your
drain cleaner and meet the needs of your application.
The correct tools and accessories allow you to do the
job successfully and safely. Accessories suitable for
use with other equipment may be hazardous when
used with this drain cleaner.
7. Clean any oil, grease or dirt from all equipment han-
dles and controls. This reduces the risk of injury due
to a tool or control slipping from your grip.
8. Inspect the cutting edges of your tools. If necessary,
have them sharpened or replaced prior to using the
Drain Cleaning Machine. Dull or damaged cutting
tools can lead to binding and cable breakage.
9. Inspect cables and couplings for wear and damage.
Cables should be replaced when they become severe-
ly worn or corroded. A worn cable can be identified
when the outside coils become flat.
Worn or damaged cables can break
causing serious injury.
Machine and Work Area Set-Up
WARNING
To prevent serious injury, proper set-up of the machine
and work area is required. The following procedures
should be followed to set-up the machine:
1. Check work area for:
• Adequate lighting
• Grounded electrical outlet

• Clear path to the electrical outlet that does not
contain any sources of heat or oil, sharp edges or
moving parts that may damage electrical cord.
• Dry place for machine and operator. Do not use
the machine while standing in water.
• Flammable liquids, vapors or dust that may ignite.
2. Position the Drain Cleaning Machine within 3′of
sewer inlet. Greater distances can result in cable
kinking or twisting.
3. Tilt machine forward and use foot to extend “kick-
stands” so that machine rests firmly on them. For
best results, extend one kickstand and rest machine
on it before extending second kickstand.
(Figure 7)
Figure 7 – Extending Kickstand
To prevent tipping during use, machine
should rest firmly on the kickstand.
4. Position the air foot switch pedal for easy operator
accessibility. Machine is designed for one person
operation.
5. Make sure FOR/OFF/REV switch is in the OFF position.
6. Securely install tool on the end of the cable
(See
Figure 5) . If the connection is not secure, the cutting
tool may fall off in use.
NOTE! Proper Tool Selection
The tools provided with this drain cleaner along with a
description of their intended use is shown in Figures 2, 3
and 4
. A good rule of thumb is to use a tool at least 1″
smaller than the line to be cleaned. The style of the
tool is determined by the nature of the job and is left up
to the operator. A good starting tool is the T-403 Cutter
(Figure 2) .
7. Plug the Drain Cleaning Machine into the electrical
outlet, making sure to position the power cord along
the clear path selected earlier. If the power cord does
not reach the outlet, use an extension cord in good
condition.
To avoid electric shock and electrical
fires, never use an extension cord that is damaged or
does not meet the following requirements:
•The cord has a three-prong plug similar to shown in
Electrical Safety Section.
•The cord is rated as “W” or “W-A” if being used out-
doors.
•The cord has sufficient wire thickness (16 AWG
below 50′/14 AWG 50′-100′). If the wire thickness is
too small, the cord may overheat, melting the cord’s
insulation or causing nearby objects to ignite.
To reduce risk of electrical shock, keep
all electrical connections dry and off the ground. Do not
touch plug with wet hands. Test the Ground Fault Circuit
Interrupter (GFCI) provided with the electric cord to
insure it is operating correctly. When test button is
pushed in, the indicator light should go off. Reactivate by
pushing the reset button in. If indicator light goes on, the
machine is ready to use. If the GFCI does not function
correctly, do not use the machine.
Operating Instructions
WARNING
Wear gloves provided with machine. Never grasp a
rotating cable with a rag or loose fitting cloth
glove that may become wrapped around the cable
causing serious injury.
Always wear eye protection to protect your eyes
against dirt and other foreign objects. Wear rubber
soled, non-slip shoes.
Do not use this machine in drains containing drain
cleaning compounds. Recommend calling a drain
cleaning professional.
Always assume the correct operating
posture in order to maintain proper balance
(Figure 8) .
Should an unexpected situation arise, this posture pro-
vides you with the opportunity to safely keep control of
the machine and cable.
• Be sure you can quickly remove your foot from the foot
switch.
• Hand must be on the cable to control its twisting
action when it hits an obstruction.
• Keep hands away from rotating drum and guide tube.
Do not reach into drum unless machine is unplugged.

Figure 8 – Proper Operating Position
1. Manually pull a sufficient length of cable out of the
drum to start the tool and cable into the sewer inlet.
2. Move FOR/OFF/REV switch into FOR (forward) posi-
tion. Do not step on the air foot switch pedal at this
time.
3. Pull 18″– 24″cable from the machine – enough to
form a slight loop – and apply slightly downward
pressure with both hands on the cable. Do not force
the cable. Allow it to feed itself into the drain.
WARNING
Before starting machine, both operator’s gloved
hands must be on cable.
4. Exert sufficient downward pressure on cable to keep
it in sewer line while depressing air foot switch pedal
to start cable rotating.
5. Pull cable out of drum and allow cable to feed itself
into the line. Always keep hand on the cable to feel the
tension.
6. Continue to feed the cable into the line until resistance
or obstruction is encountered. The condition will gen-
erally become apparent to the operator as the cable
will have a tendency to twist sideways in the opera-
tor’s hands.
7. Pull back sharply on the cable to free the cutter and
relieve the load on the cable. Slowly advance cable
back into the obstruction. Repeat this process until the
obstruction is clear. Remember, make sure the cutter
is rotating at all times and never force the cable. If
motor turns but the drum stops, the torque limiter is
slipping because of excessive force. Pull back on
cable to relieve torque and drum will begin to spin.
WARNING
Do not allow tension to build up in the cable. This
will happen if the cutting tool hits a snag and
stops turning, but the motor and its drum continue
to rotate. Torque builds until the cable suddenly
twists, potentially wrapping around your hand or
arm. This can happen quickly and without warning,
so proceed slowly and carefully as you feed the
cable into the drain. If tool gets hung up in an
obstruction, refer to Reverse Operating Instructions
in the “Special Procedures” section.
8. Several passes through thoroughly blocked drain
lines are recommended. After establishing drain flow,
increase cutter size to thoroughly clean the lines.
9. Push cable into the drum with machine in FOR (for-
ward). The machine should be kept running during the
process for thorough cleaning and uniform re-setting
of cable in the drum.
NOTE! A continuous flush of water should be used to
clean the cable and tool as they are retrieved.
10. When the tool is just inside the sewer inlet, release the
air foot switch pedal and allow the machine to come to
a complete stop.
Never retract tool from sewer inlet while
cable is rotating. Tool can whip causing serious injury.
11. Turn FOR/OFF/REV switch to OFF position and
remove cord from power source.
12. Pull the remaining cable and tool from the sewer.
Hand feed the cable into the machine.
13. Disengage the kickstands by tilting the machine for-
ward.
Special Procedures
Main Sewer Or Septic Tank Overrun
It is very important to know the approximate distance
from inlet to main sewer or septic tank. Over-running
cable too far into main sewer or septic tank can allow
cables to knot-up and prevent their return.
Reverse Operation
Running machine in reverse will cause premature failure
of cable. Use reverse only to free a tool caught in an
obstruction. If this should occur, immediately remove
foot from air foot switch pedal and allow machine to
come to a full and complete stop. Place FOR/OFF/REV
switch to REV (reverse) position. If machine has auto-
matic feed, loosen feed knob. Grasp cable with gloved
hands and pull while jogging air foot switch pedal. When
tool is dislodged and drum has stopped rotating, place

What is covered
RIDGID®tools are warranted to be free of defects in workmanship and material.
How long coverage lasts
This warranty lasts for the lifetime of the RIDGID®tool. Warranty coverage ends when the product
becomes unusable for reasons other than defects in workmanship or material.
How you can get service
To obtain the benefit of this warranty, deliver via prepaid transportation the complete product to
RIDGE TOOL COMPANY, Elyria, Ohio, or any authorized RIDGID®INDEPENDENT SERVICE CENTER.
Pipe wrenches and other hand tools should be returned to the place of purchase.
What we will do to correct problems
Warranted products will be repaired or replaced, at RIDGE TOOL’S option, and returned at no charge;
or, if after three attempts to repair or replace during the warranty period the product is still defective,
you can elect to receive a full refund of your purchase price.
What is not covered
Failures due to misuse, abuse or normal wear and tear are not covered by this warranty. RIDGE
TOOL shall not be responsible for any incidental or consequential damages.
How local law relates to the warranty
Some states do not allow the exclusion or limitation of incidental or consequential damages, so the
above limitation or exclusion may not apply to you. This warranty gives you specific rights, and you
may also have other rights, which vary, from state to state, province to province, or country to coun-
try.
No other express warranty applies
This FULL LIFETIME WARRANTY is the sole and exclusive warranty for RIDGID®products. No em-
ployee, agent, dealer, or other person is authorized to alter this warranty or make any other
warranty on behalf of the RIDGE TOOL COMPANY.
