Gener l S fety Rules*
WARNING
Read and understand all instructions. Failure to follow all in-
structions listed below may result in electric shock, fire,
and/or serious injury.
SAVE THESE INSTRUCTIONS!
Work Are
•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.
Electric l S fety
•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 out-
let 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 conditions.
Water entering a power tool will increase the risk of elec-
tric 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.
Person l S fety
•Stay alert, watch what you are doing and use com-
mon 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 inat-

tention while operating power tools may result in seri-
ous personal injury.
•Dress properly. Do not wear loose clothing or
jewelry. 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 key or wrench before turning the
tool ON. A wrench or a key left attached to a rotating
part of the power tool may result in personal injury.
•Do not overreach. 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. Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
Tool Use nd C re
•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 the power tool if the switch does not
turn it ON and OFF. Any tool that cannot be con-
trolled with the switch is dangerous and must be
repaired.
•Disconnect the plug from the power source be-
fore making any adjustments, changing accessor-
ies, or storing power tools. Such preventive safety
measures reduce the risk of starting the power tool ac-
cidentally.
•Store idle tools out of the reach of children and
other untrained persons. Tools are dangerous in
the hands of untrained users.
•aintain 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.
•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.
Service
•Tool service must be performed only by qualified
repair personnel. Service or maintenance performed
by unqualified personnel could result in a risk of injury.
•When servicing a tool, use only identical replace-
ment parts. Follow instructions in the aintenance
section of this manual. Use of unauthorized parts or
failure to follow Maintenance Instructions may create a
risk of electrical shock or injury.

•Only wear RIDGID drain cleaning gloves. Never
grasp the rotating cable with anything else, in-
cluding other gloves or a rag. They can become
wrapped around the cable, causing hand injuries.
Only wear latex or rubber gloves unde RID ID drain
cleaning gloves. Do not use damaged drain cleaning
gloves.
•Do not allow the cutter to stop turning while the
machine is running. This can overstress the cable
and may cause twisting, kinking or breaking of the
cable.
•Keep gloved hand on the cable whenever the ma-
chine is running. This provides better control of the
cable and helps prevent twisting, kinking and breaking.
•Position machine within two feet of the drain inlet
or properly support exposed cable when the dis-
tance exceeds two feet. reater distances can cause
control problems leading to twisting, kinking or breaking
of the cable.
•One person must control both the cable and the
foot switch. If the cutter stops rotating, the operator

built into the cord. A FWD/OFF/ REV switch controls drum
and cable rotation and a pneumatic foot switch provides
ON/OFF control of the motor.
The K-40 is offered in both AUTOFEED and manual ver-
sions. The AUTOFEED is integral to the four foot long
front guide hose. The AUTOFEED allows the cable to be
advanced and retrieved at a rate of 6 feet per minute.
The front guide hose used with the AUTOFEED helps to
protect fixtures and contain the liquid and debris thrown off
the cable as it is retrieved from the drain. Manual feed ver-
sions require that cable be fed in and out of the drain by
hand.
The two piece twist-lock drum will not dent or corrode, and
allows easy access to the inner drum. The inner drum al-
lows quick cable change out, helps prevent cable damage
from flip over in the drum, and reduces the likelihood of
drum leakage.
Cables are available in three sizes – 1/4", 5/16" and 3/8" di-
ameters. The 1/4" and 5/16" cables are supplied with integral
bulb augers. Some versions of these cables are supplied
with the “Speed Bump” feature to indicate to the operator
that they are near the end of the cable. 3/8" cables are avail-
able with an integral bulb head or with a quick change
coupling for attaching tools. The K-40 is equipped with a
torque arm attached to the cable to improve torque trans-
fer when most of the cable is out of the drum.

must be able to turn the machine motor off to prevent
twisting, kinking and breaking of the cable.
•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. 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
equipment. 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 glasses and
RIDGID drain cleaning gloves, and may include
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 exposed body parts exposed to
drain contents after handling or using drain cleaning
equipment. Do not eat or smoke while operating or han-
dling 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 instruc-
tions. Other uses or modifying the drain cleaning
machine for other applications may increase the risk of
injury.

- Sound emissions may vary due to your location and specific use of these tools.
- Daily exposure levels for sound need to be evaluated for each application
and appropriate safety measures taken when needed. Evaluation of expo-
sure levels should consider the time a tool is switched off and not in use. This
may significantly reduce the exposure level over the total working period.
St nd rd Equipment
All K-40 Drain Cleaning Machines come with one pair of
RID ID Drain Cleaning loves.
This machine is made to clean drains. If prop-
erly used it will not damage a drain that is in good
condition and properly designed, constructed and main-
tained. If the drain is in poor condition, or has not been
properly designed, constructed and maintained, the drain
cleaning process may not be effective or could cause
damage to the drain. (The best way to determine the
condition of a drain before cleaning is through visual in-
spection with a camera.) Improper use of this drain
cleaner can damage the drain cleaner and the drain.
This machine may not clear all blockages.

serious injury from electric shock, twisted or broken
c bles, chemic l burns, infections nd other c uses
nd prevent dr in cle ner d m ge.
Alw ys we r s fety gl sses, RIDGID dr in cle n-
ing gloves, nd other ppropri te protective e quip -
ment when inspecting your dr in cle ner. For extr
protection from chemic ls nd b cteri on the equip -
ment, we r l tex, rubber or other liquid b rrier
gloves under the RIDGID dr in cle ning gloves.
Figure 5 – RIDGID Drain Cleaning Gloves – Leather, PVC
1. Inspect the RID ID drain cleaning 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 ro-
tating cable. If the gloves are not RID ID drain
cleaning gloves or are damaged, worn out or do not
fit snugly, do not use machine until RID ID drain
cleaning gloves are available. See Figu e 5.
2. Make sure that the drain cleaning machine is un-
plugged. Inspect the power cord, round Fault Circuit
Inter rupter ( FCI) and plug for damage or modifi-
cation, such as a missing grounding prong. If any
damage or modifications are found, do not use the
tool until the cord has been properly repaired or re-
placed.
3. Clean any oil, grease or dirt from all equipment han-
dles and controls. This helps prevent the machine or
control from slipping from your grip.
4. Make sure the foot switch is attached to the drain
cleaning machine. Do not operate the machine with-
out the foot switch.
K-40 Drain Cleaning Machine
5. Inspect the drain cleaning machine for any broken,
worn, missing, misaligned or binding parts or any
other condition which may prevent safe and normal
operation. Rotate the drum and make sure that it
turns freely without binding. If any problems are
found, do not use machine until problems have been
repaired.
Figure 6 – K-40 Warning Label
6. Check that the warning label is present and firmly at-
tached. Do not operate the drain cleaning machine
without the warning label. See Figu e 6.
7. Check the motor shroud to insure that it is securely
fastened to the drain cleaner. Do not operate without
motor shroud in place. (See Figu e 6.)
8. Clean any debris from the cable and tools. Inspect ca-
bles for wear and damage. Inspect for
• Wear – wear can be identified by looking for flats on
the outside of the cable. Cables are made from
round wire, and the outside of the cable should be
rounded like the wire profile. If you can see an ob-
vious flat on the outside of the cable, it is worn and
should be replaced.
• Cable kinks – If the cable is not perfectly straight but
is slightly “wavy”, that is acceptable. Kinked cables
have a well-defined bend, and may have gaps be-
tween the coils of the cable. Slight kinks (up to 15°)
can be straightened, but all kinks weaken the cable
and can cause cable failure during use. Cables with
multiple or excessively large kinks should be re-
placed.
Warning
Label
otor
Shroud

278-104-281.10_REV. B 7
• Space between cable coils – space between the
cable coils indicates that the cable has been de -
formed. This can be caused by kinking, stretching
(mechanically pulling the cable) or running the cable
in REVERSE (REV). Cables with space between the
coils should be replaced.
• Excessive corrosion – this can be caused by storing
the cable wet or using the cable in corrosive chem-
icals used in chemical clog removers. Corrosion
weakens the cable and can make it brittle. Ex -
cessively corroded cable should be replaced.
All of these forms of wear and damage weaken the
cable and make cable twisting, kinking or breaking
more likely during use. Make sure cable is fully re-
tracted, with no more than 2" of cable out. This will
prevent whipping of the cable at start up.
9. 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.
10. Make sure that the FOR/OFF/REV switch is set to the
OFF position.
11. With dry hands, plug cord into properly grounded out-
let.
For a corded tool, test the FCI provided in the elec-
trical 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 FCI is functioning prop-
erly. If FCI is not functioning properly, unplug the
cord and do not use the drain cleaning machine until
the FCI has been repaired.
12. 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
machine 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 (Figu e 6). Release the foot switch
and let the drum come to a complete stop. Place the
FOR/OFF/REV switch into the REV position, and re-
peat above testing to confirm that the drain cleaner
operates properly in reverse. If the rotation is not cor-
rect, do not use the machine until it has been repaired.
13. With the inspection complete, move the FOR/OFF/ -
REV switch into the OFF posItion, and with dry hands,
unplug the machine.
M chine nd Work Are Set-Up
WARNING
Set up the dr in cle ning m chine nd work re c-
cording to these procedures to reduce the risk of
injury from electric shock, fire, m chine tipping,
twisted or broken c bles, chemic l burns, infec-
tions nd other c uses, nd prevent dr in cle ner
d m ge.
Alw ys we r s fety gl sses, RIDGID dr in cle ning
gloves, nd other ppropri te protective e quip ment
when setting up your dr in cle ner. For extr pro-
tection from chemic ls nd b cteri on the m chine
nd in the work re , we r l tex, rubber or other liq-
uid b rrier gloves under the RIDGID dr in cle ning
gloves. Rubber soled, non-slip shoes c n help pre-
vent slipping nd electric shock, especi lly on wet
surf ces.
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 water.
If needed, remove the water from the work area.
• Properly grounded electrical outlet. A three-prong or
FCI 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, deter-
mine 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 (urinals, etc.) to allow access
to the drain. Feeding cable through a fixture could
damage the drain cleaner and the fixture.
K-40 Drain Cleaning Machine

3. Determine the correct drain cleaning equipment for the
application. The K-40 is made for
•3/4" to 11/2" lines up to 30' long with 1/4" cable
•3/4" to 11/2" lines up to 45' long with 5/16" cable
•1
1/4" to 2" lines up to 45' long with 5/16" IC (Inner
Core) cable
•1
1/4" to 21/2" lines up to 30' long with 3/8" cable
Drain cleaners for other applications can be found by
consulting the Ridge Tool Catalog, on line at
RID ID.com or by calling Ridge Tool Tech nical
Services at 800-519-3456.
4. Confirm that the equipment to be used has been
properly inspected.
5. If needed, place protective covers in the work area.
The drain cleaning process can be messy.
6. 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 pos-
sible slip hazards. Wear appropriate footwear to help
prevent slips.
7. Position the drain cleaning machine. If using a ma-
chine without the front guide hose and AUTOFEED,
the opening of the drum must be within 2 feet of the
drain opening. If using a machine with the guide hose
and AUTOFEED, the end of the AUTOFEED must be
within 6 inches of the drain opening. The guide hose
should not be pulled tight or kinked to reach this
position. reater distances from the drain access in -
crease the risk of the cable twisting or kinking. The
K-40 can be placed either with the drum horizontal or
vertical as long as it sits squarely and firmly on the rub-
ber feet provided.
8. If the machine cannot be placed close enough to the
drain opening, extend the drain access back to 2'
from the drum opening or 6" from the AUTOFEED with
similar sized pipe and fittings. Improper cable support
can allow the cable to twist and kink and can damage
the cable or injure the operator. See Figu e 7.
Figure 7 – Example of Extending Drain to Within 2' of
Drum Opening.
9. 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.
10. Select proper tool for the conditions.
Most of the cable choices for the K-40 Drain Cleaning
Machine incorporate a bulb auger end configuration.
This is a good choice for use in small secondary drain
lines. Use of a bulb auger allows the obstruction to be
probed and fiberous blockages to be pulled out of
the line.
The C-4, C-6 and C-6IC cable available for use with
the K-40 Drain Cleaning Machine incorporate a male
coupling that allows for the installation of various
tools for cleaning drains.
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 ap-
propriate 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 block-
age can be used. enerally, 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 circum-
stances 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 RID ID Catalog and on line at RID ID.com.

11. If needed, install the tool to the end of the cable. The
T-slot coupler allows the cutting tool to be snapped into
the cable coupler. As the cutting tool is installed make
sure that the spring-loaded plunger in the coupling
on the end of the cable moves freely to retain the
tool. If the pin sticks in the retracted position, the cutting
tool may fall off in use. To remove cutting tool, insert
the pin key into the hole in the coupling to depress the
plunger and slide the coupling apart. (See Figu e 8.)
Figure 8 – Coupling and Uncoupling Tools
12. 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.
13. Confirm that the FOR/OFF/REV switch is in the OFF
position.
14. 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).
• Has sufficient wire size (16 AW for 50’ or less, 14
AW for 50’ – 100’ long). Undersized wires can
overheat, melting the insulation or causing a fire or
other damage.
When using an extension cord, the FCI on the drain
cleaner does not protect the extension cord. If the out-

infections nd other c uses.
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. Wearing RID ID drain cleaning gloves, pull cable
out of machine and feed into drain. Push cable as far
into drain as it will go. At least one foot of cable must
be in drain so that the end of the cable will not come
out of the drain and whip around when you start the
machine.
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 step on 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.
• You must be able to place at least one hand on the
cable at all times to control and support the cable
as it feeds into the drain and blockage.
• 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 Figu es 7 and 11.

4. Move the FOR/OFF/REV switch to the FOR (FOR-
WARD) position. Do not depress the foot switch
yet. FOR/OFF/REV refers to the 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.
Using M nu l Feed M chine
rasp the cable with both gloved hands and pull a short
section (6" - 12") of cable from the drum so that there is a
slight bow in the cable. loved 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. See Figu e 9.
Figure 9 – anually Feeding Cable
Starting the cable in the drain
Confirm at least one foot of cable is in the drain and the
drum opening is within 2' of drain opening. Press the foot
switch to start the machine. Feed the rotating cable into the
drain. The rotating cable will slowly work its way into the
drain as you push on the cable with gloved hands. 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 con-
trolling the foot switch. This can lead to kinking,
twisting and breaking of the cable.
If it is hard to get the cable through a trap, the following
methods or combination of methods can be used.
• First, sharp downward thrusts on the cable, both with
and without the cable turning, can help to get the tool to
pass through the trap.
• A second method is to run the drain cleaner in REV
(REVERSE) for several seconds while pushing on the
cable. Only do this long enough to get the cable started
through the trap. Running the drain cleaner in reverse
can damage the cable.
• Finally, if none of these options work, consider using a
smaller diameter or more flexible cable, or a different
drain cleaner.
Cleaning the drain
With the cable rotating in FORWARD (FOR) direction pull
short sections (6" - 12") of cable out of the drum and feed
it into the drain. Always keep both hands on the cable. As
you feed the cable into the drain, you may feel and see
the cable slow down and feel the cable start to wind or
load up (this will feel like the cable is starting to twist or
squirm). This may be a transition in the drain line (trap,
elbow, etc.) build up in the drain (grease, etc.) or the ac-
tual 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 line 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.
If using cable with the “speed bump” feature (See Figu e
10) this indicates that there is only about five more feet of
usable cable.
Figure 10 – C-13-IC SB Cable with Cable End Indicator
Speedbump is Approx. 84ʺFrom Back End of
Cable
Working the blockage
If the tool at the end of the cable stops turning, it is no
longer cleaning the drain. If the tool becomes lodged in the
blockage and power is maintained to the drain cleaner, the
cable will start to wind up (this will feel like the cable is
starting to twist or squirm). Having both hands on the
cable allows you to feel this wind up and control the
cable. As you feel the cable wind up, or if the tool stops
turning, pull back on the cable to free the tool from the
blockage. Don’t keep the cable rotating if the tool is stuck

in a blockage. If the tool stops turning and the drum keeps
rotating, the cable can twist, kink or break.
Once the tool is free of the blockage and is turning again,
you can slowly feed the rotating cutting tool back into the
blockage. Do not try to force the tool through the blockage.
Let the spinning tool “dwell” in the blockage to help com-
pletely break it up. Work the tool in this manner until it has
moved completely past the blockage (or blockages), and
the drain is flowing.
While working the blockage, the tool and cable may be-
come 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 re-
moved. See section on “Ret ieving the Cable”.
Handling a stuck tool
If the tool stops turning and the cable cannot be pulled
back from the blockage, release the foot switch while
firmly holding the cable with both hands. Do not remove
hands from cable or cable may kink, twist and break.
The motor will stop and the cable and drum will turn
backwards until the energy stored in the cable is relieved.
Do not remove hands from cable until the tension is re-
leased. 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. Be careful not to
damage the cable or tool while pulling on the cable. If the
tool will not come free from the blockage, place the
FOR/OFF/REV switch in the REV position. rasp the
cable with both gloved hands, press the foot switch for sev-
eral 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 clean-
ing 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 run-
ning 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 FOR/OFF/REV switch should be in the FOR
position – do not retrieve the cable with the FOR/OFF/REV
in the REV position, this can damage the cable. As with
feeding the cable into the drain, keep both hands on the
cable for control. The tool can become caught while being
retrieved. Pull 6" - 12" of cable from the drain at a time and
feed back into the drum. The flow of water down the line will
help to clean the cable as it is retrieved. Continue retrieving
the cable this way until the tool is just inside the drain
opening. Release your foot from the foot switch, allowing
the drum 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 could cause serious in-
jury.
Place the FOR/OFF/REV in the OFF position and with dry
hands unplug the machine. Pull the remaining cable from
the drain by hand and feed 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 M chines with Guide Hose nd
AUTOFEED
Figure 11 – Using achine With AUTOFEED
rasp the AUTOFEED with one hand and hold it so that
K-40 Drain Cleaning Machine

278-104-281.10_REV. B12
the end of the AUTOFEED is within 6 inches of the drain
opening. See Figu e 11. The guide hose helps to protect
the fixture from damage and contain the liquid thrown off
the cable as it is retrieved from the drain. If the
AUTOFEED is not kept within 6" of the drain opening, the
cable will not be properly supported and may allow the
cable to twist, kink or break.
When using a machine with a front guide hose, pay at-
tention to 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 can be harder to tell if the tool is rotating or not.
If the tool is not rotating, the drain is not being cleaned.
Figure 12 – Advance/Retract Feed Lever
Starting the cable in the drain
Confirm at least one foot of cable is in drain and end of
AUTOFEED is less than 6" from Drain opening. Press on
the foot switch to start the machine. To advance the cable
into the drain, depress the ADVANCE feed lever (Figu e 12
and 13). The rotating cable will work its way into the drain.
The person controlling the cable and the AUTOFEED
must also control the foot switch. Do not operate the
drain cleaner with one person controlling the cable and
AUTOFEED and another person controlling the foot
switch. This can lead to kinking, twisting and breaking
of the cable.
If it is hard to get the cable through a trap, the following
methods or combination of methods can be used.
• First, sharp downward thrusts on the cable, both with
and without the cable turning, can help to get the tool to
pass through the trap.
• A second method is to run the drain cleaner in REV
(REVERSE) for several seconds while pushing down on
the cable. Only do this long enough to get the cable
started through the trap. Running the drain cleaner in re-
verse can damage the cable.
• Finally, if none of these options work, consider using a
smaller diameter or more flexible cable, or a different
drain cleaner.
Figure 13 – AUTOFEED in Advance and Retrieve Position
Cleaning the Drain
Always keep one hand on the guide hose. As you feed the
cable into the drain, you may feel and see the cable slow
down and feel the guide hose start to load or wind up (this
will feel like the guide hose is starting to twist or squirm).
This may be a transition in the drain line (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 drain. This can cause the cable to twist,
kink or break. Keep end of AUTOFEED within 6" of drain
opening.
Pay attention to the amount of cable that has been fed into
the drain. If using cable with the “speed bump” feature
(See Figu e 10), the speed bump will not pass through the
depressed AUTOFEED. This indicates that it is time to re-
trieve the cable. Feeding cable into a larger drain line 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.
Working the blockage
If the tool at the end of the cable stops turning, it is no
longer cleaning the drain. If the tool 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 guide hose
is starting to twist or squirm) and buildup outside the
drain. Having a hand on the guide hose can allow you to

feel this wind up and control the cable. As you feel the
cable wind up or if the tool stops turning, immediately
release the advance feed and depress the retrieve feed
lever to free the tool from the blockage. Don’t keep the
cable rotating if the tool is stuck in a blockage. If the tool
stops turning and the drum keeps rotating, the cable can
twist, kink or break.
Once the tool is free of the blockage and the tool is turning
again, you can slowly feed the rotating tool back into the
blockage. Let the spinning tool “dwell” in the blockage to
help completely break it up. Do not try to force the tool
through the blockage. Work the tool in this manner until the
tool has moved completely past the blockage (or block-
ages), and the drain is flowing.
While working the blockage, the tool and cable may be-
come 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 re-
moved. See section on “Ret ieving the Cable”.
If the tool continues to get hung up in the blockage, stop
using the auto feed and work the cable by hand as detailed
in the Manual Feed Section. To do this, the cable must be
retrieved from the drain and the guide hose and AUTO -
FEED removed from the machine to allow proper posi-
tioning of the machine to the drain and access to the
cable. Do not try to work the cable by hand with the guide
hose and AUTOFEED in place.
Handling a stuck tool
If the tool stops turning and the cable cannot be pulled
back from the blockage, release the foot switch, maintain
a firm grip on the AUTOFEED and guide hose and release
the feed lever. Do not remove your hand from cable or
the cable may kink, twist and break. The motor will
stop and the cable and drum will turn backwards until
the energy stored in the cable is relieved. Do not remove
hand from the AUTOFEED and cable until the tension is
released. Place FOR/OFF/REV switch in the OFF position.
Freeing a stuck tool
If the tool is stuck in the blockage, place the FOR/OFF/ -
REV switch in the REV position. With both AUTOFEED
levers released press the foot switch for several seconds
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 run-
ning 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 by depressing the retrieve feed lever. The
FOR/OFF/REV switch should be in the FOR position – do
not retrieve the cable with the FOR/OFF/REV in the REV
position, this can damage the cable. As with feeding the
cable into the drain, keep hands firmly on the AUTOFEED
and guide hose for control. The tool can become caught
while being retrieved. The flow of water down the line will
help to clean the cable as it is retrieved. Continue retrieving
the cable until the tool is just inside the drain opening.
Release the feed lever and release the foot switch, allowing
the drum to come to a complete stop. Do not pull the
end of the cable from the drain while the cable is ro-
tating. The tool can whip around and could cause
serious injury.
Place the FOR/OFF/REV in the OFF position and with dry
hands unplug the machine. Pull the remaining cable from
the drain by hand and feed 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.

Cables should be thoroughly flushed with water after every
use to prevent damaging effects of sediment and drain
cleaning compounds. Remove guide hose and drain debris
from drum by tipping machine forward after every use to re-
move sediment and chemicals which can corrode cable.
To help prevent corrosion during storage, cables can be
coated with RID ID 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.
