Operation Manual

WARNING!

Read this Operator’s Manual carefully before using

this tool. Failure to understand and follow the

contents of this manual may result in electrical

shock, fire and/or serious personal injury.

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

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.

Specific Safety Information

WARNING

Read this operator’s manual carefully before

using the A150 Drain Cleaner. Failure to

understand and follow the contents of this

manual may result in electrical shock, fire

and/or serious personal injury.

Drain Cleaner Safety

• Wear leather mitt provided with machine. Never

grasp a rotating cable with a cloth or loose fitting

cloth glove. Could become wrapped around

cable and cause serious injury.

• Do not overstress cables. Keep one hand on

the cable for control when the machine is

running. Overstressing cables because of

obstruction may cause twisting, kinking or

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

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

adapter (optional) which hold 5/16”(8mm)

continuous length cables. Rotation of the

adapter is controlled by the clutch handle. The

Machine Inspection

To prevent serious injury, inspect your Drain

Cleaning Machine. The following inspection

procedures should be performed before each use.

1. Make sure the Drain Cleaning Machine is

unplugged and the directional switch is set to the

OFF position.(Figure 1)

Left: to reverse

Middle: to stop

Right: to forward

Fig 1

2. Inspect the power cord and plug for damage.

If the plug has been modified, is missing the

grounding prong or if the cord is damaged, do

not use the Drain Cleaning Machine until the

cord has been replaced.

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

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

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:

• 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.

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.
