Safety Labels
Duracable Manufacturing uses three signal words on its
safety labels and instructions. These words have the following
definitions:
A ‘Danger’ label indicates an imminently hazardous situation
that, if not avoided, will result in death or serious injury. This
signal word is to be limited to the most extreme situation,
typically for machine components that, for functional purposes,
cannot be guarded. The word ‘danger’ will be in white letters on
a red background.
A ‘Caution’ label indicates a potentially hazardous situation that,
if not avoided, may result in minor or moderate injury. It may also
be used to alert against unsafe practices. The word ‘caution’ will
be in black letters on a yellow background.
The safety label format includes the signal word and symbol, a
picture (not required), and the message.
A ‘Warning’ label indicates a potentially hazardous situation
that, if not avoided, could result in death or serious injury, and
includes hazards that are exposed when guards are removed.
It may also be used to alert against unsafe practices. The word
‘warning’ will be in black letters on an orange background.

Safe Machine Operation
Read this machine manual thoroughly before assembling or
operating the machine. Become familiar with its controls and
proper use before operating. Keep this manual in a handy place
for reference and parts replacement referral. This machine is
designed specifically for the purpose of opening and cleaning
drains. Use it for this purpose - do not use it for other purposes.
Use gloves to protect your hands. Wear them to feed and
retrieve cable. Use a material that can not be easily grabbed by
the cable. Most leather gloves and certain rubber gloves work
well.Duracable Manufacturing Company has each type available
through the Duracable Product Catalog. Also, avoid the use of
loose-fitting clothes or jewelry when operating this machine.
Keep guards in place to protect the operator from the electric
motor and electrical wiring. These guards are for safety
protection and must be in place when running the machine.
Each machine is equipped with an air foot pedal or toggle on/
o switch. The pedal allows the machine operator to turn the
machine on or o with the foot while keeping both hands on the
cable.
Select a work area free from obstruction with room to work.
Keep the machine within three feet of the pipe opening, allowing
only enough room to work. This is required to shorten the length
of exposed cable, thus providing maximum control in high-
torque situations. Take a position that is comfortable to the left
or right side of the machine for feeding or retrieving cable. For
high work openings, the machine can be placed on its back as
conditions require.
When performing a job, use the smallest blade first. Rinse the
pipe after each blade is run through the line in order to clean out
loosened debris. Then follow with the increasing sizes of blades
until the size used is one that actually scrapes the side of the pipe
or sewer. The cutting blades are flexible and can be compressed
to enter most cleanout openings. Centrifugal force created by
the spinning cable forces the blades to expand to their natural
diameter or to the walls of the pipe. It is advisable to maintain a
very keen cutting edge on the blades at all times.
Place two hands on the cable between the outlet of your
machine and the cleanout, and keep them there at all times
during operation. Your hands placed in the proper position will
provide a guide for the cable.
As the blade makes contact with an obstruction in the line, it
stops the blade from turning and builds torque in the cable.
Do not permit the blade to get hung up in an obstruction for
more than three seconds. Torque buildup can be both helpful
and dangerous. It is helpful when pulled from the obstruction
in a timely manner. When the cable is pulled away, the tension is
released and the blade turns at a high speed. When the blade is
free, feed it back into the obstruction to make use of the built-up
power to clean the line. It is dangerous because excess torque
can cause looping over of the cable. Serious injury to fingers
and hands is possible unless precautions are observed. When
retrieving cable from the line, feed the cable into the machine
until the blade is close to the cleanout opening. Shut o the
machine and hand-feed the remaining cable into the machine.
Unpacking Your Machine
The Model DM140 is shipped to you fully assembled and ready
to use. The base machine, reel, cable, and the revolving arm are
all included. When the machine arrives, remove it immediately
and inspect for damage. If any of the contents are damaged,
contact your motor freight carrier immediately.
Lubrication Maintenance
Caution: Do not over oil these points.
• Reel Shaft and Reel Bearings - Check and re-tighten set screws
during the first 24 to 48 hours of operation. The reel shaft
requires monthly lubrication. Use a multipurpose grease or
heavy oil. Keeping the shaft lubricated means the reel will
slide freely and will not “freeze” to the shaft and need to be
repaired. The reel bearings require some light oil monthly.
• Belt-Check tension during the first 24 to 48 hours of operation.
• Belt Tension - Ideal deflection is 1/4”. Over tensioning shortens
belt and bearing life.
• Air Foot Pedal - Check for wear or stress cracks.
Cable Care Instructions
Take care of your cable for optimum performance. The
recommended care procedure is as follows:
• Break in a new cable. To relieve the stress on new cable that
has been coiled since its manufacture, put it in a clean line and
run it for 10 minutes.
• Oil the cable once a week.
• Rinse the cable immediately after each use with the hottest
water available. This is especially important if the cable was in
acid or alkali during use.
• When one end of the cable begins to show wear, rewind and
use the opposite end. (Tip: order the same kind of end fittings
on both ends of the cable.)
• If the cable kinks, cut out the kink and splice the cable ends
together.
Installing New Cable
• Remove cable from the carton and lay it in a straight line on
the floor.
• Make sure the reel is secured on the machine and the revolving
arm rotates freely.
• Feed the cable through the revolving arm.
• The revolving arm must be turning counterclockwise while
loading the cable.
• Install the guide tube, cable end, and cutting blade. The cable
end may be bent to desired form (as shown on the next page).

Frame
The frame on Model DM140 is a continuously welded
uni-body frame made of steel tube with a heavy-duty
casted front bearing mount. Non-marring rubber pads
do not leave marks on the customers’ floors.
Head Bearing
The DM140 is equipped with a heavy-duty casted self-
aligning head bearing, which makes sure that the reel
stays properly aligned when it spins. This increases the
life span, making for a longer-lasting reel. The head
bearing holds the reel in place, as well as allowing quick
release of the reel. Just loosen the four wing nuts and
everything slides o for fast reel changes.
Electrical Wiring
The machine’s electrical wiring is located in the conduit
box on the right side of the motor, housing both the
forward/reverse switch and the air foot switch.
The Ground Fault Circuit Interrupter (GFCI) is built into
the electrical cord for added safety. The GFCI protects
the operator against electrical shock or electrocution. A
great feature is a switch guard that protects the forward/
reverse switch from accidentally being bumped and
going into reverse.

Handle with Care
Every year many people are injured or killed by electricity.
Most of these accidents could have been prevented with
simple precautions and careful use of electricity. Following are
some tips to help avoid electrical accidents. Read through this
information. Be sure you understand its importance. If you have
questions or feel you may have a potential electrical hazard, tell
your supervisor or call a qualified electrician immediately.
General Electrical Guidelines
Remember, electricity is always trying to make a circuit. It can
travel through an electric wire, metal pipe, or even your body.
Electrical shock can occur when you come in contact with an
energized electrical unit and a good conductor. Shock can range
from a slight tingle to a severe burn, or death by electrocution.
Electrical accidents happen in everyday situations. Most
electrocutions occur in a wet environment or when an electrical
product is being repaired or installed. Think about, and take
precautions against, potentially dangerous situations.
When disconnecting electrical cords, pull on the plug rather
than the cord to avoid damage. Use rubber gloves and rubber
boots or insulated shoes to protect yourself, especially if you
are in a wet or damp environment. Before using this machine,
make sure a properly grounded, three-prong, 110-volt outlet is
available. Where it is not available, use a three-prong adapter
and connect the grounding lug to a known ground. Never cut o
a grounding prong to fit a two-prong outlet. This eliminates the
ground protection.
Electrical Procedures
Do not leave the machine plugged in when not in use. Even with
the switch o, a machine can shock or electrocute its handler.
The Model DM140 machine must be grounded to protect the
operator from shock. This is accomplished by using the Ground
Fault Circuit Interrupter (GFCI) Cord to ensure proper grounding.
Check electrical cords before each use for signs of damage.
Repair or replace cords which are pinched, cracked, frayed, or
worn. Remember, the GFCI oers no protection against electric
shock for wiring preceding it in the system. Your GFCI is direct-
wired to the machine, plug the GFCI into the power source
receptacle.
Discontinue use and repair immediately any machine that causes
the slightest shock or is damaged in any way. It could lead to a
serious electrical shock or electrocution.
Inspect the machine daily for wear or damage that might expose
live electrical parts.
Ground Fault Circuit Interrupters (GFCI)
A GFCI works by detecting changes in electrical current flow.
It breaks the circuit before serious injury can occur. For your
protection, heed the “DANGER” warning on the machine cover
and use the GFCI cord. The GFCI must be tested before each use.
Use the following procedure:
• Insert the unit into a 110-volt, AC-grounded receptacle;
• Push the “test” button in - the red indicator light should go o;
• Push the “reset” button in - if the red indicator light goes on,
the unit is ready for use;
• Do not use the unit if the light does not go on when reset;
• Do not use the unit if the indicator light remains on when the
test button is pushed.
Extension Cords
• Use extension cords only when necessary.
• Position cords in use to prevent tripping hazards. Do not place
them in areas where they can be damaged by trac.
• Avoid coiling extension cords during use to prevent possible
overheating of the cord.
• Discard cracked or damaged cords.
• The following cord sizes and lengths should be observed
according to the National Electrical Code when using this
machine:
• 12 gauge wire - 75’ of cord, maximum.
• 14 gauge wire - 50’ of cord, maximum.
• 16 gauge wire - 25’ of cord, maximum.
• Cord sizes smaller than 12 gauge should not be used for 3/4
HP motors. Larger gauge cords can be run greater distances,
but are not practical because of their size and weight.
• To protect your motor, observe the guidelines mentioned. If
you have a run more than 75’, use a generator to reduce your
cord length from the power source to a working distance
within these guidelines.
Overhead Power Lines
• When working outdoors, keep clear from overhead power
lines in all directions.

You can attach end fittings and splice cores to DuraFlex cable using a chemical bonding process, which means you can make quick cable repairs on
the job—without welding. With Loctite Primer and Loctite Retaining Compound, you can quickly create a dependable bond that is as strong as a
conventional weld. Please note that these products are not the same thread-locking compounds available in hardware stores and plumbing-supply
houses, they are heavy-duty, permanent-bonding compounds made especially for jobs such as bonding cable fittings.
