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.

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 Company 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 switch. Use of
the air foot switch 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 cutting 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
Company recommends a PCFR unit be used on every Model
DM55 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.
UnpackingYour Machine
The Model DM55 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.
DisassemblingYour Machine
To disassemble the Model DM55 machine, reverse the
assembly process
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 switch pedal 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 Company 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-based 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.

Model DM55
Frame
The new and improved frame is constructed of an
aluminum alloy that is structurally as strong as steel.The side
rail design has support brackets that allow the motor, gear and
head casting assemblies to be bolted directly to the frame. In
addition, these parts are enclosed by impact-resistant cover
panels for safety and appearance.
Electrical Wiring
The machine’s electrical wiring is run through the top
of the frame. The Ground Fault Circuit Interrupter (GFCI) is
built into the electrical cord to protect the operator against
electrical shock or electrocution.
The air foot switch is standard equipment and allows
operators to turn the machine on and off with the foot while
the hands stay on the cable.
RPM/Drive
The standard King machine has a 3/4 HP industrial motor
and can be ordered in one of three different speeds: 145 rpm,
175 rpm or 215 rpm.The gearbox has a 10:1 gear ratio for more
torque and power than any other machine on the market.This
added power means you can easily add reels of cable to clean
lines longer than 300 feet. The gearbox cantilever weight
capacity is 900 pounds. Another feature is the 3/4” thick axle
for unsurpassed durability.
Front Assembly
The front assembly provides the housing for two switches:
the forward/off/reverse switch and the air foot switch. The
front assembly is covered by a molded, one-piece, high-
impact cover. The assembly is custom-tted and bolted to the
frame.
Maneuverability
The King’s wheels provide greater mobility and ground
clearance, while still tting through a standard 30” door.
A narrower wheel is available. A telescoping handle is
standard.

Electrical Safety
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 DM55 machine must be grounded to protect the operator
from shock.This is accomplished by using the Ground Fault
Circuit Interrupter Cord (GFCI) 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.
