Safety Labels
Duracable Manufacturing Company uses three signal
words on its safety labels and instructions.These words have
the following denitions:
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.

Information and Specifications
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 specically 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 cannot be easily grabbed by
the cable. Most leather gloves and certain rubber gloves work
well. Duracable Manufacturing has each type available through
the Duracable Product Catalog. Also, avoid the use of loose-
tting 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. Use of the air
foot pedal to operate the machine is required for safe operation.
This allows the machine operator to turn the machine on or off
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 rst. 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 blades are exible 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 ngers
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
off the machine and hand-feed the remaining cable into the
machine.
Use of a Power Cable Feed and Return (PCFR) will reduce stress
and strain on both the drain cleaning machine and the service
technician. Duracable Manufacturing recommends a PCFR unit
be used on every Model DM30 machine.This unit mounts in
front of the head casting assembly and with movement of a
handle will feed or retrieve cable from a sewer line. Mounting
time for the unit is minimal.
Unpacking Your Machine
The Model DM30 is shipped to you with the following parts:
the base machine, a reel, a revolving arm, a oating ring, and
a oating ring attachment. When it arrives, remove the parts
immediately and inspect for damage. If any of the contents are
damaged, contact your motor freight carrier immediately.
AssemblingYour Machine
• Set the base machine in a down position on its rails.
• Pick up the reel with the cone shape to the front of the machine
(toward the switches), and slide it onto the reel shaft. Be sure
the orange drive lugs slide into the openings in the back of the
reel and engage fully.
• Place the oating ring inside the reel and mount it to the tail
piece or cable using the oating ring attachment. Attach a tail
piece (10’ of cable) to the oating ring attachment.
• Feed the tail piece through the revolving arm until about 1” of
the cable shows.
• Position the revolving arm inside the reel.
• Place the revolving arm with cable extended into the rear side
of the head bearing.
• Position the extension shaft on the revolving arm into the
center of the reel bearing.
• Slide the tail piece through the head bearing. Attach the full
length of cable to the tail piece and feed cable back into the
machine.
MovingYour Machine
Break the machine down into lighter-weight components to
move it to and from the job site.To do this, wrap the GFCI cord
and the air foot pedal cord in a convenient spot on the machine,
remove the revolving arm from its assembled position (leave
the cable inside it and keep it with the reel), and remove the
reel assembly. Various accessories are available from Duracable
Manufacturing to assist and protect the operator during the
moving process.
Lubrication Maintenance
Caution: Do not over oil these points.
• Head Bearing Assembly -The roller bearing, located in the
front assembly, requires monthly lubrication. Use a grease gun
to lubricate the zerk tting with multipurpose grease. A lithium-
base grease is recommended.
• Reel Shaft and Reel Bearings -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.
• Wheels - A light oil on the axle every month keeps the wheels
rolling freely instead of ‘freezing’ to the axle.

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 ttings
on both ends of the cable.)
• If the cable kinks, cut out the kink and splice the cable ends
together.
Reel Attachment
The reel you select is set in place and slipped onto the reel shaft.
Drive lugs are mounted on the drive plate and slip through the
opening in the back of the reel.The reel is held in place by the
revolving arm.

Duracable®Machine Manual
Model DM30
As shown above with 21PRS reel, wide wheels, PCFR and a stubbed GFCI
cord. (See options on the next page.)
Frame
The Model DM30 is a powerful machine, constructed of durable
materials and engineered with your safety in mind.The basic frame
is constructed of aluminum alloy.This alloy is structurally as strong
as steel. A double tube frame adds stability, yet the total weight of
the machine, including the 21” reel and revolving arms, is only 75
pounds.
Electrical Wiring
The machine’s electrical wiring is ran through the top of the frame
so normal wear will not expose the wiring.The Ground Fault Circuit
Interrupter (GFCI) is built into the electrical outlet cord for added
safety.The air foot switch is standard on the DM30.This switch allows
the operator to turn the machine on and off with the foot while the
hands stay on the cable.
RPM/Drive
The Model DM30 features a 1/2 HP, 200 rpm Industrial Fractional
Horse Power motor that easily tackles lines up to 6” in diameter with
1/2” or 5/8” cable.
Front Assembly
The front assembly provides the housing for three switches: the on/
off switch, the air foot switch, and the spring loaded on/off/reverse
switch.The front control assembly is covered by a molded one-piece,
high-impact polycarbonate cover. It is custom-tted and bolted to the
frame.
Maneuverability
The Model DM30 has wheels for mobility and ground clearance as
well as a telescoping handle.The wide wheels are standard and there
are also optional narrow wheels.
Cable and Reel Selections
The DM30 was designed to handle several reel sizes. These provide
the operator with exibility of cable size and length.

Handle with Care
Most of us take electricity for granted. It has been with us since
the day we were born. We use it every day for light, phone,
home appliances, tools, and other equipment that helps us
maintain our standard of living. Although electricity is one of
the safest energy forms, we tend to forget how powerful and
dangerous it can be if not used properly.
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 qualied 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 off a grounding prong to t 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 off, a machine can shock or electrocute its handler.
The DM30 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 offers 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 ow.
It breaks the circuit before serious injury can occur. For your
protection, heed the “DANGER” warning on the machine cover
an 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
off;
• 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 traf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, including 25’ of GFCI cord.
• 14 gauge wire - 50’ of cord, including 25’ of GFCI cord.
• 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.
• Check the location of power lines before using a ladder. Use
approved ladders made of non-conductive material.
• Never place a ladder where it can slide into a power line.
• When carrying or moving a ladder or equipment, lower it to
avoid touching a power line.
• Never assume that a wire is safe to touch.
