General Safety Rules
*
WARNING
Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.
SAVE THESE INSTRUCTIONS!
Work Area Safety
• Keep 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. Power 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 qualified
electrician if you are in doubt as to whether the outlet is properly grounded. If the tool should electrically
malfunction or break down, grounding provides 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 electric shock if your body is
grounded.
• Do not expose power tools to rain or wet condi-
tions. Water entering a power tool will increase the risk
of electric shock.
• Do not abuse the cord. Never use the cord to carry
the tool 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 electric shock.
• When operating a power tool outside, use an out-
door extension cord marked “W-A” or “W”. These
cords are rated for outdoor use and reduce the risk of
electric shock.
Personal Safety
• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not
use a tool while you are tired or under the influence

of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
• Dress properly. Do not wear loose clothing or jew-
elry. Contain long hair. Keep your hair, clothing 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 be-
fore plugging in. Carrying power tools with your finger
on the switch or plugging in power tools that have the
switch ON invites accidents.
• Remove adjusting keys or wrenches before turning
the tool ON. A wrench or a key left attached to a rotat ing part of the power tool may result in personal injury.
• Do not overreach. Keep proper footing and balance
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 clamps 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 the tool. Use the correct tool for your
application. The correct tool will do the job better
and safer at the rate for which it was designed.
• Do not use tool if the switch does not turn it ON and
OFF. Any tool that cannot be controlled with the switch
is dangerous and must be repaired.
• Disconnect the plug from the power source be-
fore making any adjustments, changing accessories, or storing the tool. Such preventive safety mea-
sures 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 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 accidents are
caused by poorly maintained tools.
K-750 Drain Cleaning Machine
• 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.

or properly support exposed cable when the distance exceeds three feet. Greater distances can
cause control problems leading to twisting, kinking or
breaking of the cable. Twisting, kinking or breaking
cable may cause striking or crushing injuries.
• One person must control both the cable and the
foot switch. If the cutter stops rotating, the operator
must be able to turn the machine motor off to prevent
twisting, kinking and breaking of the cable. Twisting,
kinking or breaking cable may cause striking or crushing injuries.
• Do not operate the machine in REV (reverse) rota-
tion except as described in this manual. Operating
in reverse can result in cable damage and is used to
back the tool out of blockages.
• Keep hands away from rotating drum and guide
tube. Do not reach into drum unless machine is unplugged. Hand may be caught in the moving parts.
• Do not wear loose clothing or jewelry. Keep your
hair and clothing away from moving parts. Loose
clothing, jewelry or hair can be caught in moving parts.
• Always use appropriate personal protective equip-
ment while handling and using drain cleaning e quip ment. Drains may contain chemicals, bacteria
and other substances that may be toxic, infectious,
cause burns or other issues. Appropriate personal
protective equipment always includes safety glass es and RIDGID drain cleaning gloves, and may in-
clude equipment such as latex or rubber gloves, face
shields, goggles, protective clothing, respirators and
steel-toed footwear.
• Practice good hygiene. Use hot, soapy water to
wash hands and other body parts exposed to drain
contents after handling or using drain cleaning equipment. Do not eat or smoke while operating or handling
drain cleaning equipment. This will help prevent contamination with toxic or infectious material.
• Do not operate this machine if operator or ma-
chine is standing in water. Operating machine while
in water increases the risk of electrical shock.
• Only use drain cleaning machine to clean drains of
recommended sizes according to these instructions. Other uses or modifying the drain cleaning ma-
chine for other applications may increase the risk of
injury.

Pre-Operation Inspection
WARNING
Before each use, inspect your drain cleaning machine and correct any problems to reduce the risk of
serious injury from electric shock, twisted 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 inspecting your drain cleaner. For extra protection from chemicals and bacteria on the equipment, wear latex, rubber or other liquid barrier
gloves under the RIDGID drain cleaning gloves.
1. Inspect the RIDGID drain cleaning gloves or mitts
(“gloves”). Make sure they are in good condition with
no holes, tears or loose sections that could be caught
in the rotating cable. It is important not to wear improper or damaged gloves. The gloves protect your
hands from the rotating cable. If the gloves are not
RIDGID drain cleaning gloves or are damaged or
worn out, do not use machine until RIDGID drain
cleaning gloves are available.
See Figure 6.
Figure 6 – RIDGID Drain Cleaning Gloves – Leather, PVC
2. Make sure that the drain cleaning machine is unplugged and inspect the power cord, Ground Fault
Circuit Interrupter (GFCI) and plug for damage. If the
plug has been modified, is missing the grounding
prong or if the cord is damaged, to avoid electrical
shock, do not use the machine until the cord has
been replaced by a qualified repair person.
3. Clean any oil, grease or dirt from all equipment handles and controls. This helps prevent the machine
or control from slipping from your grip.

parking lot or driveway) with no obstructions or items
that could become wrapped around the cable.
2. When using an AUTOFEED to load cable, the rotating
cable will tend to walk sideways. To prevent this,
place suitable stops (such as wood blocks) on either
side of the cable at 10 foot intervals.
3. After properly inspecting and setting up the drain
cleaner, attach the cable to the pigtail as shown in
Figure 4
. Make sure that no one is in the area around
the cable. Tighten the AUTOFEED knob so that the
roller touches the cable plus one additional turn. With
the FOR/OFF/REV switch in the FOR position, press
the foot switch to start the drum turning. Move the feed
handle in the opposite direction of the cable rotation to
feed the cable into the drum.
4. When 10' of cable is left outside of the drum, step off
the foot switch and move the FOR/OFF/REV switch to
OFF. Loosen the AUTOFEED knob and manually
feed the remaining cable into the drum. Do not use the
AUTOFEED to put all of the cable in the drum. The
cable end can whip around and cause serious injury.
Attaching Front Guide Hose (Optional Accessory
For Use With AUTOFEED)
1. Pull approximately 4' of cable from the drum.
2. Slide Front Guide Hose over the cable, adapter end
first. Pull plunger pin head up and place adapter over
the mounting collar on the AUTOFEED. Make sure
plunger pin locks into the hole in the mounting collar.

4. Make sure the foot switch is attached to the drain
cleaning machine. Do not operate the machine without the foot switch.
5. Inspect the drain cleaning machine for the following
items:
• Proper assembly and completeness
• Any broken, worn, missing, mis-aligned or binding
parts
• Smooth and free movement of the AUTOFEED
handle throughout range. Rotate the drum and
make sure that it turns freely without binding.
• Presence and readability of the warning label
(see
Figure 7)
.
• Presence and proper adjustment of the belt guard.
Belt guard should be adjusted so that the gap between the guard and the drum is no more than 1/4".
(See Figure 3.)
• Any condition which may prevent safe and normal
operation.
If any problems are found, do not use the drain
cleaner until the problems have been repaired.
Figure 7 – Warning Label
6. Clean any debris from the cable and cutting tools.
Inspect cables for wear and damage. Inspect for:
• Obvious flats worn into the outside of the cable
(cable is made from round wire and the profile
should be round).
• Multiple or excessively large kinks (slight kinks up to
15 degrees can be straightened).
• Space between cable coils indicating that the cable
has been deformed by stretching, kinking, or running
in reverse (REV).
• Excessive corrosion from storing wet or exposure to
drain chemicals.
All of these forms of wear and damage weaken the
cable and make cable twisting, kinking or breaking
more likely during use. Replace worn and damaged
cable before using drain cleaner.
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
outlet. Test the GFCI provided in the electrical cord to
insure that it is operating correctly. When the test
button is pushed in, the indicator light should go off.
Reactivate 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.

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 according to these procedures to reduce the risk of injury from electric shock, fire, machine tipping,
twisted 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 protection from chemicals and bacteria on the machine 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 electrician.
• 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, determine 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 present 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 5/8" cable
• 4" to 8" lines up to 200' long with
3
/4" cable
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.
10
K-750 Drain Cleaning Machine
Figure 9 – AUTOFEED Size Setting
7. Take the drain cleaning machine to the work area
along the clear path. If the machine needs to be
lifted, use proper lifting techniques. Use care moving
equipment up and down stairs, and be aware of possible slip hazards. Wear appropriate footwear to help
prevent slips.
8. Position the drain cleaning machine so that the K-750
cable outlet is within 3 feet of the drain access. Great er distances from the drain access increases the
risk of the cable twisting or kinking. If the machine
cannot be placed with the cable outlet within 3' of the
drain access, extend the drain access back to within
3' of the cable outlet with similar sized pipe and fittings. Improper cable support can allow the cable to
kink and twist and can damage the cable or injure the
operator.
See Figure 10.
If using front guide hose,
place machine so that at least 6" of guide hose can be
placed in drain opening.
Figure 10 – Example of Extending Drain to Within 3' of
Cable Outlet
9. Tilt the machine forward and use your foot to rotate
one kickstand at a time to the backside of the wheel.
The machine should firmly rest on the kickstands.
The kickstands stabilize the machine and help prevent
tipping or walking during use. If working on soft ground,
it may be necessary to place wood or other solid material under the drain cleaner for proper support.
Figure 11 – Setting Kickstands
10. Evaluate the work area and determine if any barriers
are needed to keep bystanders away from the drain
cleaner and work area. The drain cleaning process can
be messy and bystanders can distract the operator.
11. Select proper tool for the conditions.
If the nature of the obstruction is unknown, it is good
practice to use a straight or bulb auger to explore the
obstruction and retrieve a piece of the obstruction for
inspection.
Once the nature of the obstruction is known, an appropriate tool can be selected for the application. A
good rule of thumb is to start by running the smallest
available tool through the blockage to allow the backed
up water to start flowing and carry away the debris and
cuttings as the drain is cleaned. Once the drain is open
and flowing, other tools appropriate for the blockage
can be used. Generally, the largest tool used should
be no bigger than the inside diameter of the drain
minus one inch.
Proper tool selection depends on the specific circumstances of each job and is left to the users’
judgement.
A variety of other cable attachments are available
and are listed in the Accessories section of this
manual. Other information on cable attachments
can be found in the RIDGID Catalog and on line at
www.RIDGID.com or www.RIDGID.eu.

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
2
) for 50'
(15.2m) or less, 14 AWG (2.5mm2) for 50' – 100'
(15.2m – 30.5m) long). Undersized wires can overheat, 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, including 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 respirators, to prevent burns and infections. For extra pro-
tection from chemicals and bacteria on the machine 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.
Figure 12 – In Operating Position, Manually Feeding
Cable
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.
12
K-750 Drain Cleaning Machine
• You must be able to place at least one hand on the
cable at all times to control and support the cable.
• You must be able to reach the FOR/OFF/REV
switch.
This operating position will help to maintain control of
the cable and machine.
See Figure 12.
4. Move the FOR/OFF/REV switch to the FOR (FORWARD) position. Do not depress the foot switch yet.
FOR/OFF/REV refers to the drum/cable rotation and
not to the direction of cable movement. Do not rotate
the cable in reverse except as specifically described
in these instructions. Running the drain cleaner in
REV can damage the cable.
Operation
The K-750 Drain Cleaning Machine is available in two
different feed configurations, either manual feed or AUTO FEED. A K-750 supplied with the AUTOFEED can either
feed the cable with the AUTOFEED (feed lever position) or
by manually pulling the cable from the drum and feeding it
into the drain. With the AUTOFEED you can switch back
and forth between operating methods as needed. A K-750
without the AUTOFEED can only be used manually.
Feeding The Cable Into The Drain
Manual Operation
Confirm that at least one foot (.3 m) of cable is in the drain.
Grasp the exposed cable with both gloved hands equally
spaced and pull 6"-12" of cable out of the drum so that
there is a slight bow in the cable. Gloved hands must be
on the cable to control and support the cable. Improper
cable support can allow the cable to kink or twist and can
damage the cable or injure the operator. Make sure that
the cable outlet of the drain cleaner is within 3' of the drain
opening.
Depress the foot switch to start the machine. The person
controlling the cable must also control the foot switch. Do
not operate the drain cleaner with one person controlling
the cable and another person controlling the foot switch.
This can lead to twisting, kinking and breaking of the
cable. Feed the rotating cable into the drain. The rotating
cable will work its way into the drain as you push on the
cable with gloved hands. Do not allow the cable to build up
outside the drain, bow or curve. This can allow the cable
to twist, kink or break.
When the cable has been fed into the drain opening,
pull 6"-12" more cable from the drum and continue feeding the rotating cable into the drain.
AUTOFEED Operation
Confirm that at least one foot (.3 m) of cable is in the drain.
Tighten the AUTOFEED knob
(Figure13)
so that the roller
touches the cable plus one additional turn. Do no overtighten the knob – this can cause premature failure of the
AUTO FEED or cable.
Grasp near the center of the exposed length of cable
with a gloved hand. Gloved hand must be on the cable to
control and support the cable. Improper cable support can
allow the cable to kink or twist and can damage the cable
or injure the operator. Make sure that the cable outlet of
the drain cleaner is within 3' of the drain opening. Place the
other hand on the AUTOFEED lever. AUTOFEED lever
should be in neutral (Vertical) position
(see Figure 13).
See “Using Machine With A Front Guide Hose” if using a
guide hose.
Figure 13 – AUTOFEED Lever Positions
(Cable Turning In FOR Direction)
NOTE: Rate of cable advance or retrieve varies by
handle movement from neutral.
Depress the foot switch to start the machine. The person
controlling the cable must also control the foot switch. Do
not operate the drain cleaner with one person controlling
the cable and another person controlling the foot switch.
This can lead to twisting, kinking and breaking of the
cable. With the cable rotating, move the AUTOFEED
control handle in the same direction that the cable rotates.
This will cause the cable to feed out of the machine. The
further the control handle from the neutral position, the
faster the cable will be fed (up to 20' per minute, maximum). The rotating cable will work into the drain as you
control the cable with your gloved hand. Do not allow
the cable to build up outside the drain, bow or curve.
This can allow the cable to twist, kink or break.

Figure 14 – Operating the K-750 using the AUTOFEED
If it is difficult to get the cable through a trap or other fitting, the following methods or combinations of methods
can be used.
• Sharp thrusts of the cable, both with and without
the cable rotating, can help the cable through a
trap.
• In some cases with the switch in the OFF position,
rotating the drum by hand can change the orientation of the cutter to allow it to more easily negotiate the fitting.
• Run the drain cleaner in REV (REVERSE) rotation
for several seconds while pushing on the cable.
Only do this long enough to get the cable started
through the trap. Running the cable in reverse can
damage the cable.
• Use a flexible leader between the tool and the
cable.
• If these options don’t work, consider using a smaller
diameter or more flexible cable, or a different drain
cleaner.
Cleaning The Drain
As you feed the cable into the drain, you may see the
cable slow down or build up outside the drain. Always
keep your hands on the cable. You may feel the cable
start to wind or load up (this may feel like the cable is starting to twist or squirm). This may be a transition in the drain
(trap, elbow, etc.), build up in the drain (grease, etc.) or the
actual blockage. Feed the cable slowly and carefully. Do
not let cable build up outside the drain. This can cause the
cable to twist, kink or break.
Pay attention to the amount of cable that has been fed into
the drain. Feeding cable into a larger drain, septic tank or
similar transition may cause the cable to kink or knot
and prevent removal from the drain. Minimize the amount
of cable fed into the transition to prevent problems. Each
wrap of the cable in the drum is approximately four feet
long. If using
5
/8" cable with a 3/4" pigtail, do not feed the
connection through the AUTOFEED. This could damage
the AUTOFEED.
If an additional length of cable is needed,
see the section
“Adding Additional Cable”.
Working The Blockage
If the end of the cable stops turning, it is no longer cleaning the drain. If the end of the cable becomes lodged in the
blockage and power is maintained to the drain cleaner, the
cable will start to wind up (this may feel like the cable is
starting to twist or squirm). Having a hand on the cable allows you to feel this wind up and control the cable. If the
cable end stops turning or if the cable starts to wind up, immediately pull the cable back from the obstruction:
• Manual Operation – pull back on the cable to free
the cable end from the blockage.
• AUTOFEED Operation – move the feed lever in the
direction opposite the cable rotation to free the cable
end from the blockage.
Don’t keep the cable rotating if the cable is stuck in a
blockage. If the cable end stops turning and the drum
keeps rotating, the cable can twist kink or break.
Once the cable end is free of the blockage and turning
again, you can slowly feed the cable end back into the
blockage. Do not try to force the cable end through the
blockage. Let the spinning end “dwell” in the blockage to
completely break it up. Work the tool in this manner until
you have moved completely past the blockage (or blockages) and the drain is flowing. Manual operation is usually
the best choice if the cable repeatedly gets stuck when
using the AUTOFEED. If using an AUTOFEED machine
manually, the feed knob may need to be loosened, and
the feed lever placed in the neutral position.
While working the blockage, the cable and tool may become clogged with debris and cuttings from the blockage.
This can prevent further progress. The cable and tool
need to be retrieved from the drain and the debris removed.
See section on “Retrieving the Cable”
.
14
K-750 Drain Cleaning Machine
Handling A Stuck Tool
If the tool stops turning and the cable cannot be pulled
back from the blockage, immediately release the foot
switch while firmly holding the cable. Do not remove
hands from cable or cable may kink, twist and break. The
motor will stop and the cable and drum may turn backwards until the energy stored in the cable is relieved. Do
not remove hands from cable until the tension is released. Place FOR/OFF/REV switch in OFF position.
Freeing A Stuck Tool
If the tool is stuck in the blockage, with the FOR/OFF/REV switch in the OFF position and the foot switch released, try pulling the cable loose from the blockage. If
the tool will not come free from the blockage, place the
FOR/OFF/REV switch in the REV position. Grasp the
cable with both gloved hands, press the foot switch for
several seconds and pull on the cable until it is free of the
blockage. Do not operate the machine in the REV position any longer than required to free the cutting tool
from the blockage or cable damage can occur. Place the
FOR/OFF/REV switch in the FOR position and continue cleaning the drain.
Retrieving The Cable
Once the drain is open, start a flow of water down the
drain to flush the debris out of the line. This can be
done by running a hose down the drain opening, turning
on a faucet in the system or other methods. Pay attention
to the water level, as the drain could plug again.
With water flowing through the drain, retrieve the cable
from the line. The flow of water will help to clean the
cable as it is retrieved. The FOR/OFF/REV switch should
be in the FOR position – do not retrieve the cable with the
switch in the REV position, this can damage the cable. As
with feeding the cable into the drain, cables can be caught
while being retrieved.
• Manual Operation – With both gloved hands equally
spaced on the exposed cable for control, pull 6"-12"
lengths of cable from the drain at a time and feed it
into the drum .
• AUTOFEED Operation – With one hand near the
center of the exposed length of cable, move the feed
lever in the direction opposite the cable rotation to
retrieve the cable. The rotating cable will work its way
out of the drain and back into the drum.
Continue retrieving cable until the cable end is just inside
the drain opening. Release the foot switch and allow the
machine to come to a complete stop. Do not pull the
end of the cable from the drain while the cable is rotating.
The cable can whip around and cause serious injury.
Pay attention to the cable during retrieval as the cable end
can still become stuck.
Place the FOR/OFF/REV switch in the OFF position.
Pull the remaining cable from the drain with gloved hands
and feed back into the drain cleaner. If needed, change
the tool and continue cleaning following the above process. Several passes through a line are recommended for
complete cleaning.
Using Machine With A Front Guide Hose
The front guide hose is an optional accessory to help
protect fixtures and contain the liquid and debris thrown
off of the cable. It can only be used with an AUTOFEED.
Using the Front Guide hose can decrease feedback
from the cable, making it harder to tell what conditions
the cable is encountering. This may increase the possibility of damage to the cable. Using the front guide
hose makes it more difficult to switch back a forth between manual and AUTOFEED operation.
Using a machine with the front guide hose is similar to
using a machine with just the AUTOFEED. Follow instructions for AUTOFEED operation with the following
exceptions:
• When setting up the machine, insert the guide hose
at least 6" into the drain.
• Instead of holding the cable, hold the guide hose.
See Figure 15.
Always control the guide hose and
properly support the cable to prevent the cable from
twisting, kinking or breaking.
Figure 15 – Using Machine with Guide Hose
15
K-750 Drain Cleaning Machine
When using a front guide hose, pay attention how the
guide hose feels in your hand and watch the drum rotation. Because the guide hose is over the cable, there
is less sensitivity to the loading of the cable, and it is
harder to tell if the tool is rotating or not. If the tool is not
rotating, the drain is not being cleaned.
If the tool continues to get hung up in the blockage, stop
using the AUTOFEED (leave the feed lever in the neutral position) and work the cable manually. To do this, the
cable must be retrieved from the drain and the guide
hose removed to allow proper positioning of the machine
to the drain and access to the cable. Do not try to work the
cable by hand with the front guide hose in place.
When retrieving the cable, be sure to stop the cable before the tool is pulled into the end of the guide hose to
prevent damage.
Adding Additional Cable
If more cable is necessary to clean the drain than is
available in the machine drum, use the following procedures to add additional cable.
1. Make sure that the FOR/OFF/REV switch is in the
OFF position and the machine is unplugged.
2. Pull the cable connection from the drum. If using
the AUTOFEED, the feed knob may need to be loosened.
3. Disconnect the cable from the pigtail and secure the
cable so it cannot slip down the drain.
4. If loading another cable in the existing drum, see
“Installing Cable” in the Assembly section.
5. Make sure that the drain cleaning machine is properly
set up. Attach the end of the cable in the drain to the
cable in the drum. Feed any excess cable back into
the drum.
6. Resume cleaning the drain. Make sure that the cable
is rotating and up to speed before feeding cable in.
Drum Removal and Installation
1. Make sure that the FOR/OFF/REV switch is in the
OFF position and the machine is unplugged.
2. If needed, remove AUTOFEED from machine by
unscrewing mounting bolt with 3/4" wrench. Bolt and
AUTOFEED will come off as one.
See Figure 16.
Figure 16 – Removing AUTOFEED
3. Push down on motor table to release belt tension
and slip belt off of the drum.
See Figure 17.
Figure 17 – Releasing Belt Tension
Push Down
Motor Table
16
K-750 Drain Cleaning Machine
4. Use 3/4" wrench to remove the bolt that holds the
drum to the machine frame.
See Figure 18.
Figure 18 – Removing Drum Bolt
5. Lay machine on it’s back
(see Figure 19)
. Use proper
lifting technique to lift the drum off of its mounting position. A drum with 100' of cable can weigh as much
as 150 pounds. In some cases, two people will be
needed to handle a drum of cable.
Figure 19 – Removing Drum
6. Reverse steps 2-5 to reassemble a drum to the K-750
frame. Exercise care when standing the machine
up to tighten the drum bolt.
Maintenance Instructions
WARNING
FOR/OFF/REV switch should be OFF and machine
unplugged before performing any maintenance.
Always wear safety glasses and RIDGID drain clean ing gloves and other appropriate protective equipment when performing any maintenance.
Cleaning
The machine should be cleaned as needed with hot,
soapy water and/or disinfectants. Do not allow water to
enter motor or other electrical components. Make sure
unit is completely dry before plugging in and using.
Cables
Cables should be thoroughly flushed with water after
every use to prevent damaging effects of sediment and
drain cleaning compounds. Flush cable with water and
drain debris from drum by tipping machine forward after
every use to remove sediment, etc. which can corrode
cable.
To help prevent corrosion during storage, cables can be
coated with RIDGID Cable Rust Inhibitor. Once the cable
is clean and dry, pull the cable from the drum. While
manually feeding the cable back into the drum, wipe the
Cable Rust Inhibitor on the cable with a cloth.
Do not apply the Cable Rust Inhibitor to a rotating
cable. The cloth and your hand can become entangled in
the cable, and Cable Rust Inhibitor can be slung from rotating cable.
AUTOFEED
After each use, hose out AUTOFEED assembly with
water and lubricate with lightweight machine oil.
Lubrication
Lubricate motor as per instructions on motor.
Lubricate machine with general purpose grease at
grease fitting (located at connection of guide tube and
drum) If drum is changed or removed, once a week if
used every day: once a month if used less.
Front Guide Hose
After use, flush the guide hose with water and drain.
When dry, a small amount of Cable Rust Inhibitor can be
placed in the guide hose to help keep it flexible.
