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. 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 electrical shock if your body is
grounded.
• Don’t expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electrical shock.
• Do not abuse cord. Never use the cord to carry the
tools or pull the plug from an outlet. Keep cord
away from heat, oil, sharp edges or moving parts.
Replace damaged cords immediately. Damaged
cords increase the risk of electrical shock.
• When operating a 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
electrical shock.
• Use only three-wire extension cords which have
three-prong grounding plugs and three-pole receptacles 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 outlet receptacles.
The GFCI on the machine power cord will not prevent
electrical shock from the extension cords.
• Keep all electric connections dry and off the
ground. Do not touch plug with wet hands. Reduces
the risk of electrical shock.
Personal Safety
• Stay alert, watch what you are doing and use common 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 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, jew-
elry, or long hair can be caught in moving parts.
• Avoid accidental starting. Be sure switch is OFF be-
fore plugging in. Carrying tools with your finger on the
switch or plugging tools in that have the switch ON in-
vites accidents.
• Remove adjusting keys or 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 balance at all times. Proper footing and balance enables
better control of the tool in unexpected situations.
• Use safety equipment. Always wear eye protection.
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 plug from the power source before
making any adjustments, changing accessories, or
storing the tool. Such preventive safety measures re-
duce risk of starting 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.
• 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 replacement 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.

severely worn or corroded. A worn cable can be identified when the outside coils become flat or having
several kinks throughout the cable.
Worn or damaged cables can break
causing serious injury.
Machine Set-Up
K-40 Drain Cleaner:
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 place
the machine in water.
• Flammable liquids, vapors or dust that may ignite.
2. Place the machine in the most convenient position, flat
on the working surface or upright on its back and
close to the drain opening.
3. Position the air foot switch pedal for easy operator
accessibility. Machine is designed for one person operation. Air-operated foot switch has an extra long
rubber air cord which frees up the operator to hand-feed
the cable or operate the autofeed and guide hose.
4. Make sure FOR/OFF/REV switch is in the OFF po-
sition.
5. 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.
K-40 Battery Charger
Battery Charging Procedure:
Before using the battery charger, read all
the instructions included with the battery and charger.
1. Locate the charger so the cord and charger will not be
stepped on, tripped over or be subjected to damage.
Do not expose charger to wet environment such as
rain or snow.
2. Charge battery cartridge in temperatures above 50°F
(10°C) and below 104°F (40°C). Store tool and battery
cartridge in location where temperatures do not exceed 120°F (49°C).
3. Plug the battery charger into the proper A/C voltage
source. The charging light will flash in green color
(Figure 13).

WARNING
WARNING
WARNING
WARNING
Ridge Tool Company 9
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 pins on line plug that are similar in size
and shape to those of the plug on the charger.
• 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.
Do not attempt to use a step-up trans-
former, an engine generator or DC power receptacle.
4. Insert the battery cartridge so that the plus and minus
terminals on the battery cartridge are on the same
sides as their respective markings on the battery
charger. Insert the cartridge fully into the port so that
it rests on the charger port floor.
5. When the battery cartridge is inserted, the charging
light color will change from green to red and charging
will begin. The charging light will remain lit steadily during charging. When charging is completed, the
charging light color will change from red to green.
NOTE! Charging time will be approximately one hour.
Charge only Makita type batteries. Other
types of batteries may burst causing personal injury.
6. After charging, unplug the charger from the power
source. Always cover the battery terminals with the
battery cover when the batter cartridge is not used.
Important Charging Notes
1. When you charge a new battery cartridge or a battery
cartridge which has not been used for a long period of
time, it may not accept a full charge. This is a normal
condition and does not indicate a problem. You can
recharge the battery cartridge fully after discharging it
completely and recharging a couple of times.
2. If you charge a battery cartridge from a just-operated tool or a battery cartridge which has been left in
a location exposed to direct sunlight or heat for a
long time, the charging light may flash in red color. If
this occurs, wait for a while. Charging will begin after
the battery cartridge cools. The battery cartridge will
cool faster if you remove the battery cartridge from the
battery charger.
3. If the charging light flashes alternately in green and red
color, a problem exists and charging is not possible.
The terminals on the charger or battery cartridge are
clogged with dust or the battery cartridge is worn out
or damaged.
4. If you wish to charge two battery cartridges, allow
15 minutes between chargings on the battery charger.

WARNING
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.
Be very careful when cleaning drains where chemical compounds have been used. Avoid direct
contact of the skin and especially the eyes and facial area as serious burns can result. Rinse hands
thoroughly after contact with chemical compounds.
Cleaning Drain Line Using Machine
Without Autofeed
1. Place the FORWARD/REVERSE switch in the FORWARD position.
Power unit must be completely stopped
before moving FORWARD/REVERSE switch. REVERSE
position is used only when removing cable from an obstruction or retrieving the cable after the drain is cleared.
2. Pull out enough cable by hand to insert into the drain
opening and hand-feed the cable into the drain until it
stops feeding easily (Figure 15).
3. Turn the machine on by depressing the foot pedal.
4. Continue hand-feeding the cable slowly until the drain
is opened or blockage is encountered. Keep your
cable hand close to the drain opening to keep control
of the cable and help prevent cable flip-over.
Keep your other hand on the extended
cable between K-40 and your cable hand to steady the
exposed cable and maintain cable control.
5. When you reach the blockage, work the cable back
and forth to clear the obstruction. At this point,
progress depends on the type of tool being used and
nature of the blockage. Advance cable slowly.
6. If cable/blade gets hung up in obstruction, release the
foot pedal and let motor come to a complete stop
before reversing.
7. Place FORWARD/REVERSE lever in REVERSE position.
8. Press foot pedal only until cable/blade is free of obstruction. Release foot pedal immediately.
NOTE! Only run machine in REVERSE if relieving cable
from a blockage or retrieving the cable with the
Autofeed.
9. As soon as cable/blade is free and motor has stopped,
return FORWARD/REVERSE lever to FORWARD
position.
10. Continue feeding cable by following Steps 4 through
9 until through obstruction.
11. The speedbump cable end indicator, located approximately 84″ from the back end of the cable, is a
1
/2″ expanded bump in the cable to warn the operator
there is only 6′ of usable cable left. (Figure 23)
12. To withdraw cable from line with machine running,
leave FORWARD/REVERSE lever in FORWARD
position and slowly pull cable from drain.
13. As excess cable is retrieved from line, hand-feed
cable back into K-40 Drum.
14. Turn machine OFF just prior to cable or tool emerg-
ing from drain opening. Retrieve by hand as cable or
tool may contain debris and splash work area.
Cleaning Drain Line Using Guide Hose
With Autofeed
1. Place FORWARD/REVERSE switch into FORWARD
position. Keep autofeed close to drain opening, approximately 2″ – 6″ (Figure 16).
2. Hand feed approximately one to two feet of cable
into the drain opening.
3. Turn machine ON by depressing foot pedal and be
sure entire cable is spinning before continuing.
4. Depress the autofeed’s feed actuator lever and feed
cable into drain.
NOTE! Know how long your run of pipe is prior to clean-
ing. Running too much cable can damage your
equipment and the drain.

5. Feed cable into drain until obstruction is encountered
or cable begins to bind up.
6. If cable begins to bind up, release feed actuator lever
and pull cable back slightly by hand. Refeed cable into
blockage again. If advancing the cable with the
autofeed is difficult, discontinue using it and advance
the cable by hand until the line clears.
7. Once drain is open and flowing, continue feeding additional cable with autofeed to clean rest of drain.
8. The speedbump cable end indicator, located approximately 84″ from the back end of the cable, is a
1
/2″ expanded bump that will not pass through the
autofeed and warns the operator it is time to retrieve
the cable. (Figure 23)
9. To retrieve cable, stop machine completely.
10. Switch the FOR/REV switch to REV.
11. Turn machine ON and depress the feed actuator
lever. It will automatically retrieve the cable from the
drain.
12. Turn machine OFF just prior to cable or tool emerg-
ing from drain opening. Retrieve by hand as cable or
tool may contain debris and splash work area.
HINT! If your cable tool/retriever bulb has hooked onto
a solid blockage such as a rag or ball or hair, it
may be wise to pull the cable out of the drain by
hand. Reversing the cable to retrieve it may
cause the blockage to unscrew off the cable.
NOTE! The only adjustment on the autofeed is the round
top adjustment screw under the feed actuator
lever. Its purpose is to adjust the distance the feed
actuator lever has to be depressed to engage
the different size cables. Turn knob clockwise to
accommodate the larger 3/8″ cable and turn knob
counter clockwise to accommodate the
5
/16″ cable. No
adjustment is necessary direct from the factory.
Special Procedures
Loading Cable Into Drum
Your K-40/K-40B is supplied with an inner drum that fits
snugly inside a two-piece drum that allows easy changeout of cable. To access the inner drum feature:
1. On units supplied with mounting bracket, remove one
mounting bracket bolt and loosen the remaining one.
Swing mounting bracket to OPEN position (Figure 17).
2. Loosen the four screws that hold the drum front to the
drum back. Loosen each screw about 3 full turns
(Figure 18).

3. Separate the drum front from the drum back by twisting apart (Figure 19).
4. Lift the inner drum, with cable, out of its cradled fit.
5. Fit the new inner drum into the drum back and draw
about a foot of cable out of the inner drum (Figure 20).
6. Pass the exposed cable head through the drum front
assembly, align the drum front with the drum back,
and rotate drum front to lock into position. Tighten the
screws.
Torque Arm
The K-40/K-40B is supplied with a torque arm inside
the inner drum (Figure 21) and attached to the back
end of the cable (Figure 22).
The torque arm retains the cable inside the inner drum of
the K-40/K-40B and greatly enhances the performance of
the machine. It is adjustable to different sizes of cable
ranging from 1/4″ through 3/8″.
Cable End Indicator
The C-13-IC SB Cable has a “speedbump” at the back
end of the cable (Figure 23). This bump in the cable will
warn you to stop feeding cable out of the drum. The
“speedbump” is most effective on K-40 units with the
autofeed accessory. The bump will not pass through the
autofeed during operation of the machine. To pass the
bump through the autofeed, lift the actuator handle.
Continuing to feed the cable past the speedbump may result in the cable coming out of the inner drum requiring
you to reload the cable.

Maintenance Instructions
WARNING
Make sure machine is unplugged from power
source before making any adjustment.
1. Cables should be thoroughly flushed with water after
each use to prevent damaging effects of drain cleaning compounds. RIDGID Cable Rust Inhibitor should
be applied prior to storage.
When not in use, store cables indoors to prevent deterioration by the elements.
NOTE! Cables should be replaced when they become
severely corroded or worn. A worn cable can
be identified when outside coils of cables become flat.
2. Use a clean cloth to wipe the unit off. Oil, grease
and other substances may cause deterioration. Certain
cleaning agents and solvents damage plastic parts.
Some of these are: gasoline, carbon tetrachloride,
chlorinated cleaning solvents, ammonia and household detergents that contain ammonia. Avoiding use
of these and other types of cleaning agents minimizes the probability of damage.
3. It is a good idea to regularly drain the inner drums of
any captured liquid. Simply hold the machine nose
down and drain excess liquid each time the machine
is used.
NOTE! Remove the Guide Hose accessory for ease of
draining.
4. Store the unit where it is cool and dry. Avoid those
areas where the temperature will drop to 0°F or exceed +120°F.

Autofeed
A drop of grease to the following areas once a month will
extend the life of the Autofeed unit and keep it well maintained.
a. Top of Large Top Adjustment Screw
b. Threads on Bottom of Top Adjustment Screw
c. Outside Diameter of Top Roller Holder housing
There are no grease fittings to worry about, however, the
autofeed will accumulate dirt, grease and debris over time.
It is a good idea to periodically remove the autofeed unit
and clean with cleaning solvent and a firm brush.
It is also a good idea to apply a light grease once a
week, to the autofeed roller bearing surface. This will extend the life of the bearings and keep them free to operate
properly.
