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
atmospheres, such as in the presence of
flammable liquids, gases, or dust. Tools create
sparks which may ignite the dust or fumes.
•Keep bystanders, children, and visitors away
while operating a 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.
•Do not expose electrical tools to rain or wet
conditions. Water entering a 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 tool outside, use an
outdoor 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. Insufficient
conductor size will cause excessive voltage
drop, loss of power.
•Before using, test the Ground Fault Circuit
Interrupter (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 plugs or tool 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 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 before plugging in. Carrying tools with
your finger on the switch or plugging tools in
that have the switch ON invites accidents.
Remove adjusting keys or switches before

2
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 the plug from the power source
before making any adjustments, changing
accessories, or storing the tool. Such preventive
safety measures reduce the risk of starting the
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.

breaking of the cable and result in serious injury.
• Position machine within two feet of inlet. Use
Front End Guide Hose when it is difficult to
locate the machine near the access or clean out.
Greater distances can result in cable twisting or
kinking.
• Do not operate machine in (REV) reverse.
Operating machine in reverse can result in cable
damage and is used only to back tool out of an
obstruction.
• Be careful when cleaning drains where
cleaning compounds have been used. Avoid

3
direct contact with skin and eyes. Serious burns
can result from some drain cleaning compounds.
• Do not operate machine if operator or machine
is standing in water. Will increase the risk of
electrical shock.
• Wear safety glasses and rubber soled, non-slip
shoes. Use of this safety equipment may prevent
serious injury.
• Only use the A150 to clean drain lines up to 6″
in diameter. Follow instructions on the use of the
machine. Other uses or modifying the drain
cleaner for other applications may increase the
risk of injury.
Description, Specifications and
Standard Equipment
Description
The A150 is a portable Drain Cleaning Machine
designed to clean 11/4”to 6”drain lines.
Applications include sink, shower and floor
drains. Capable of running 2 different size cables:
16mm and 22mm.
The machine is driven by a 750W motor that has
a grounded electrical system. A toggle switch
provides FORWARD/OFF/REVERSE control of
the motor.
The A150 is designed to use 5/8”(16mm) and
7/8”(22mm) diameter sectional-type cable that
has a quick change coupling system for
disconnecting tools. The cable is manually fed in
and out of the drain and rotates at a speed of
460 RPM. The rotation of the cable is controlled
by a clutch handle. The cable stops instantly
when the clutch handle is released.
The A150 is also designed to use with the

3. Inspect the Drain Cleaning Machine for any
broken, missing, misaligned or binding parts as
well as any other conditions which may affect the
safe and normal operation of the machine. If any
of these conditions are present, do not use the
Drain Cleaning Machine until any problem has
been repaired.
4. Lubricate the Drain Cleaning Machine, if
necessary, according to the Maintenance
Instructions.
5. Use tools and accessories that are designed
for your drain cleaner and meet the needs of
your application.
The correct tools and accessories allow you to
do the job successfully and safely. Accessories
suitable for use with other equipment may be
hazardous when used with this drain cleaner.
6. Clean any oil, grease or dirt from all
equipment handles and controls. This reduces
the risk of injury due to a tool or control slipping
from your grip.
7. Inspect the cutting edges of your tools. If
necessary, have them sharpened or replaced
prior to using the Drain Cleaning Machine. Dull
or damaged cutting tools can lead to binding and
cable breakage.
8. Inspect cables and couplings for wear and
damage. Cables should be replaced when they
become severely worn or corroded. A worn
cable can be identified when the outside coils
become flat. Worn or damaged cables can break
causing serious injury.
Machine Set-Up
WARNING
Do not place machine in water. Water entering
the motor can result in electrical shock.
To prevent serious injury, proper set-up of the
machine and work area is required. The
following procedures should be followed to
set-up the machine:
Set-Up For 5/8″ (16mm) Sectional Cable
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 use
the machine while standing in water.
• Flammable liquids, vapors or dust that may
ignite.
2. Position the Drain Cleaning Machine within 2′
of drain inlet. Greater distance can result in
cable twisting or kinking.
3. Make sure FOR/OFF/REV switch is in the
OFF position.
4. Insert first cable into front of machine (female
end first) and push through until approximately
one foot remains out the front of the machine
(Figure 2).
Figure 2 –Inserting Cable Into Front Of Machine
Never couple more than one cable at a time.
Cable will extend behind rear guide tube.
6. Select and install the proper tool to the end of
the cable. The T-Slot Coupler allows the tool to
be snapped into the cable coupler (Figure 3). To
remove tool, use the pin key to depress the
plunger and slide the coupling apart.
Figure 3 –Coupling and Uncoupling Tools
7. Plug the Drain Cleaning Machine into the
electrical outlet, making sure to position the

5
power cord along the clear path selected earlier.
If the power cord does not reach the outlet, use
an extension cord in good condition.
Warning
To avoid electric shock and electrical fires, never
use an extension cord that is damaged or does
not meet the following requirements:
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.
Set-Up For 5/16″Cable Adapter (Optional)
1. Make sure FOR/OFF/REV switch is in the
OFF position.
2. Pull ten inches of cable from cable adapter
and slide into back of A150.
3. Lift plunger pin on cable adapter and depress
clutch handle on machine to allow cable adapter
to slip into drilled hole (Figure4). Be sure plunger
has locked into machine.
Fig 4
NOTE! By pulling down hard on clutch handle,
the adapter will spin. With an upward snap of
clutch handle, the adapter will stop instantly,
preventing overrun or kinking. The built-in brake
increases life of cable.
4. Position machine as close to line opening as
possible and follow same set-up procedure as
described for use with 5/8″ sectional cable.
5. Check that the adapter stops instantly when
clutch handle is pulled upward. If adapter coasts,
see Special Procedures section to adjust brake.
Operating Instructions
WARNING
Wear mitts with rivets provided with machine.
Never grasp a rotating cable with a rag, loose
fitting cloth or leather 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
cleaning compounds have been used. Wear
gloves when handling cable and avoid direct
contact to the skin and especially the eyes and
facial area as serious burns can result. Do not
operate if clutch handle is damaged or does not
function properly. Clutch is a safety feature
designed to stop rotation of cable or adapters
when released.
It is important to know approximate distance
from inlet to main sewer or septic tank.
Over-running cable too far into main sewer or
septic tank can cause cables to knot up and
prevent their return through small line.
Cleaning Drain using 5/8″Sectional Cable
1. Assume the correct operating posture in order
to maintain proper balance.
Should an unexpected situation arise, this
posture provides you with the opportunity to
safely keep control of the machine and cable.
• Be sure you can quickly release the clutch
handle.
• Hand must be on the cable to control its
twisting action when it hits an obstruction.
• Must have access to FOR/OFF/REVERSE
switch.
2. Without turning the machine on, pull sufficient
cable out of the machine to start tool and cable
into the drain inlet. Push cable into inlet as far as
it will go.
3. Pull enough extra cable through machine to
form almost a half circle between machine and

6
line opening.
4. Hold cable loosely in mitted hand. Put
FOR/OFF/REVERSE switch in FOR (forward)
position.
NOTE! The motor will start but cable will not
rotate.
5. With mitted hand on cable, push down on
clutch handle with opposite hand to engage
cable. Push down on top of the cable loop with a
definite snap to advance the cable.
Fig 5
NOTE! A slow or gradual engaging of the clutch
handle causes excessive wear of the jaw set.
The clutch is instant-acting and returning clutch
handle to its original position frees cable
instantly.
6. As soon as excess cable has gone into line,
release clutch handle and pull six to ten inches
of cable out of machine with mitted hand.
7. Continue to feed the cable into the line until
resistance or obstruction is encountered. This
will become apparent to operator as it will be
difficult to feed additional cable into line and/or
the cable will have a tendency to twist sideways
in operator’s hands.
8. If cable loads down in the obstruction, relieve
load by pulling back on cable with short, quick
jerks to free cutter. Slowly advance cable back
into the obstruction.
Repeat this process until the obstruction is clear.
Remember, make sure the cutter is rotating at all
times and never force the cable. At this point,
progress depends upon the sharpness of the
tool and nature of the obstruction.
WARNING
Do not allow tension to build up in the cable. This
will happen if the cutting tool hits a snag and
stops turning, but the motor and cable continue
to rotate. Torque builds until the cable suddenly
twists, potentially wrapping around your hand or
arm. This can happen quickly and without
warning, so proceed slowly and carefully as you
feed the cable into the drain. Releasing clutch
handle will stop the cable rotating and releases
the torque. If tool gets hung up in an obstruction,
refer to Reverse Operating Instructions in the
“Special Procedures” section.
9. Once obstruction is cleared, it is
recommended that operator flush debris from
line with running water. Repeat Step 8 several
times if necessary for thorough cleaning job and
then work cable through additional stoppages as
required.
10. To add cable, the following procedure should
be followed:
• After reaching the end of each cable section,
turn the machine OFF.
• Secure the cable by looping it in the line (Fig 6).
Figure 6 –Looping Cable In Line
This procedure is especially useful when
cleaning a line that has rapid fall, such as
working from a stack line.
• With line secured, insert another section of
cable in through the front of the machine (female
end first) until approximately one foot remains
out the front of the machine.
• Attach cable to cable in line and resume
operation.
11. To retrieve cable from drain line, the
following procedure should be followed:

7
• Leave FOR/OFF/REV switch in FOR (forward)
position.
• Push down on clutch handle to engage cable.
With mitted hand pull cable out of line (if possible)
or hold cable against edge of inlet to thread the
cable out until loop forms in front of the machine.
NOTE! By holding the cable against the edge of
the inlet, in the FOR (FORWARD) position, the
rotation will rapidly “thread” the cable out of the
line.
• When loop forms, release clutch handle and
push excess cable back through machine.
Disconnect one section at a time. When
disconnecting sections, remember to turn unit off
and secure cable in line.
• Once section of cable is removed, insert the
secured cable in through the front of the
machine and continue removing sections until
tool on last section of cable is just inside sewer
inlet. Never retract tool from sewer inlet while
cable is rotating. Tool can whip causing serious
injury.
12. Turn FOR/OFF/REV Switch to OFF position.
13. Pull remaining cable and tool from sewer.
After using, thoroughly flush and drain cables,
couplings and tools with water due to damaging
effects of some drain cleaning compounds.
Cleaning Drain Using 5/16″Cable Adapter
(optional)
1. Assume the correct operating posture in order
to maintain proper balance.
Should an unexpected situation arise, this
posture provides you with the opportunity to
safely keep control of the machine and cable.
• Be sure you can quickly release the clutch
handle.
• Hand must be on the cable to control its
twisting action when it hits an obstruction.
• Must have access to FOR/OFF/REVERSE
switch.
2. Pull out enough cable by hand to insert into
the drain opening and hand-feed the cable into
drain until it stops feeding easily. Push cable
down drain line
keeping your control hand close to the drain
opening.
3. Hold cable loosely in mittened hand, put
FOR/OFF/REV SWITCH in FOR (forward)
position.
NOTE! The motor will start but cable will not
rotate.
4. With mitted hand on cable, push down on
clutch handle with opposite hand to engage
adapter.
5. 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.
6. 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.
7. If cable gets hung up in the obstruction,
release the clutch handle to stop the rotation of
the cable. Refer to “Reverse Operation” in the
“Special Procedures” section.
8. Once obstruction is cleared, it is
recommended that operator flush debris from
line with running water.
Repeat Step 6 several times if necessary for
thorough cleaning job and then work cable
through additional stoppages as required. Cable
is not attached inside drum. When approaching
end of cable, keep hand securely on cable to
avoid losing it down the drain.
9. To withdraw cable from line with machine
running, leave FOR/REV lever in FORWARD
position and slowly pull cable from drain.
10. As excess cable is retrieved from line,
hand-feed cable back into A150.
11. Release clutch handle just prior to cable or
tool emerging from drain opening. Cable or tool
may contain debris and splash work area. Never
retract tool from sewer inlet while cable is
rotating. Tool can whip causing serious injury.

8
12. Turn FOR/OFF/REV Switch to OFF position.
13. Pull remaining cable and tool from sewer.
Special Procedures
Reverse Operation
Running machine in reverse will cause
premature failure of cable. Use reverse only to
free a tool or cable caught in an obstruction. If
this should occur, immediately release clutch
handle and place FOR/OFF/REV switch to OFF
position. After motor comes to a complete stop,
place FOR/OFF/REV switch in the REV (reverse)
direction. Engage clutch handle only until cable
or tool is free of obstruction. Once it is free,
release clutch handle immediately. Turn unit
OFF. Run unit in FOR (forward) direction and
follow normal operating procedure.
Never operate this machine in REV (reverse) for
any other purpose. Operating in reverse can
damage a cable and cause serious injury.
Maintenance Instructions
WARNING
Make sure machine is unplugged from power
source before performing maintenance or
making any adjustment.
Lubrication
Lubricate machine with grease at grease fitting
(located on jaw housing) once a week if used
every day; once a month if used less. Place a
drop of oil on each of the bearing points, thrust
bearing, clutch jaws, etc., at least once a year.
Cables
Cables should be thoroughly flushed with water
to prevent damaging effects of sediment and
drain cleaning compounds.
Periodically lubricate cables and couplings.
When not in use, store cables indoors to prevent
deterioration by the elements.
Cables should be replaced when they become
severely corroded or worn. A worn cable can be
identified when outside of coils become flat.
Cable Containers
Cable container on 5/16″cable adapter (optional)
should be periodically cleaned.
1. Remove cable from the cable adapter. Cable
is not attached to inside of drum.
2. Remove three 1/4″ screws holding tube and
flange to the drum.
3. Clean inside of drum and flange assembly.
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.
4. Reinstall the flange assembly to the drum and
replace cable.
Machine Storage
Motor-driven equipment must be kept indoors or
well covered in rainy weather. Store the machine
in a locked area that is out of reach of children
and people unfamiliar with drain cleaners. This
machine can cause serious injury in the hands of
untrained users.
If machine has been exposed to freezing
weather, unit must be run for ten (10) to twenty
(20) minutes without load to warm up. Failing to
do this will result in frozen bearings. If machine is
exposed to weather for a period of time,
moisture will form across motor windings
causing motor to burn out.
