Your Mini-Rooter XP is designed to give you years of trouble-free,

profitable service. However, no machine is better than its operator. We

therefore suggest you read these instructions through carefully before

using your machine on the job. This will enable you to operate the Mini-

Rooter XP more efficiently and more profitably. Failure to follow these

instructions may cause personal injury to operator or damage to

equipment.

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. Call General’s customer service department at 412-771-

6300 if you have any questions.

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. Power tools create sparks which may ignite the dust or fumes.

• Keep bystanders, children, and visitors away while operating a power 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 UL approved tester or 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 electric shock if your body is grounded.

• Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase the risk

of electric shock.

• Do not abuse the 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 electric shock.

• When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These

cords are rated for outdoor use and reduce the risk of electric 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 electric shock.

• Use proper extension cords. Insufficient conductor size will cause excessive voltage drop and 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 electric 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 electric shock from the extension cords.

• Keep all electric connections dry and off the ground. Do not touch plugs or tools with wet hands.

Reduces the risk of electric 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 medication. 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. Plugging in tools that have the

switch on invites accidents.

• Remove adjusting keys or switches before turning the tool on. A wrench or key that is left attached to

a rotating part of the tool may result in personal injury.

• Do not overreach. 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 preventative safety measures reduce the risk of starting the tool accidentally.

• Store idle tools out of 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 electric shock or injury.

Specific Safety Information

• Wear leather gloves provided with the machine. Never grasp a rotating cable with a rag or cloth

glove. Could become wrapped around cable and cause serious injury.

• Never operate machine with belt guard removed. Fingers can get caught between belt and pulley.

• Do not overstress cables. Keep gloved hand on the cable for control when machine is running.

Overstressing cables because of an obstruction may cause twisting, kinking, or breaking of the cable and

may result in serious injury.

• Position machine within two feet of drain opening. Greater distances can result in cable twisting or

kinking.

• Machine is designed for one-person operation. Operator must control foot switch and cable.

• Do not operate machine in reverse (REV). Operating machine in reverse can result in cable damage

and is used only to back cutting tool out of an obstruction.

• Keep hands away from rotating drum and distributor tube. Do not reach into drum unless machine

is unplugged. Hand may be caught in the moving parts resulting in serious injury.

• Be careful when cleaning drains where cleaning chemicals have been used. Avoid direct contact

with skin and eyes. Drain cleaning chemicals can cause serious burns as well as damage the cable.

• Do not operate machine if operator or machine is standing in water. Will increase risk of electrical

shock.

• Wear safety glasses and rubber soled, non-slip shoes. Use of this safety equipment may prevent

serious injury.

• Before starting each job, check that the cable in the drum is not broken or kinked, by pulling the

cable out and checking for wear or breakage. Always replace worn out (kinked or broken) cables with

genuine GENERAL replacement cables.

• Only use this tool in the application for which it was designed. Follow the instructions on the

proper use of the machine. Other uses or modifying the drain cleaner for other applications may

increase risk of injury.

GROUND FAULT CIRCUIT INTERRUPTER (GFCI)

Your machine is equipped with a ground fault circuit interrupter, which protects you against shock if a short

circuit should occur. Check that receptacle is properly grounded. Test the GFCI before each use.

1. Plug into 120-volt receptacle.

2. Push test button. Indicator light will go out and power to machine should cut off.

3. If light does not go out when test button is pushed, equipment should not be used until proper repairs can

be made.

4. To restore power after test, push reset button. With the reset button depressed, if the machine doesn't

start, stops while running, or if the operator experiences a mild shock, do not use the machine! Take it to

a motor repair center or return it to the factory for repairs.

Note: The section of cord between the wall plug and the GFCI is not in the protected circuit.

Boring Gimlet BG Starting tool, to remove loose objects.

1-1/2” U-Cutter 1-1/2UC Finishing tool, works well in grease stoppages.

2” Side Cutter Blade 2SCB Finishing tool, for scraping inside edges of pipe.

Note: There are no fixed rules for what cutter to use. If one tool doesn't take care of a stoppage,

simply try another.

OPERATING INSTRUCTIONS

SET-UP

1. Place machine within approximately two feet of drain opening. Be sure the Mini-Rooter XP Guide Tube

(XP-GT) is in place. If you can’t place the machine this close to the drain opening, run the cable through

the optional Guide Tube Extension (GTE) or a metal guide tube to prevent cable whipping. On manual

feed machines, always keep a gloved hand on the cable.

2. Position the foot pedal for easy accessibility. The machine is designed for one-person operation. Be sure

you can quickly remove your foot from the pedal in an emergency.

3. Be sure the motor switch is in the off position.

4. Select the proper cutting tool (See Cutter Application Chart—Table 2). A good tool to start with is the

Arrow Head or Boring Gimlet. After the line is opened, follow with larger blades, which scrape the inside

edges of the pipe, assuring a real cleaning job.

5. Insert the cutter into the female connector at the end of the 3/8" or 1/2" cable and tighten the connecting

screw and lock washer firmly in place.

OPERATION

1. Begin by pulling the cable from the drum and sliding it into the drain as far as it will go.

2. Tighten the knob at the top of the Power Cable Feed so that the feed roller presses against the cable. Be

sure not to over tighten since this could cause excess cable wear. Note: The Power Cable Feed is

designed for use with 1/2” and 3/8” cables only.

3. The feed lever controls the feeding rate and direction of the cable. Move the lever down to feed

the cable out of the drum. The further the lever is moved downward, the faster the cable will feed

out. Move the lever up to retract the cable into the drum. When the lever is in the middle (neutral)

position, the cable will spin in place.

4. Move the motor switch to the forward position. Then with a gloved hand on the guide tube or cable,

depress the air foot pedal to start machine.

5. Feed the cable into the line and against the obstruction with a firm, even pressure. Adjust the feeding rate

to the resistance met. Do not force the cable – let the cutter do the work. The job won’t get done any

faster and you could damage the cable.

DO NOT FORCE THE CABLE - LET THE CUTTER DO THE WORK.

6. Don't leave too much slack in the cable since this will cause whipping. If the cable starts to bend or build

up too much twist, release pressure on the foot pedal and rotate the drum in the opposite direction to

relieve the twist on the cable. Push any excess cable back into the drum and then continue.

7. If you're having trouble getting around tight bends, try putting the machine in reverse while applying steady

pressure. Don't do this for more than a few seconds at a time since this could cause tangling in the drum

or kinking.

8. If you still can't get around the bend, you're probably using too large a cable. Switch to a 3/8" diameter

cable, or even a smaller one if necessary. (See Cable Application Chart—Table 1)

9. When the cable reaches the stoppage, put feed in neutral. Then allow the cable to progress forward

slowly, chewing into the stoppage as it goes. This slow forward movement will reduce stress on the cable

while doing a more thorough cleaning job. A back and forth action often works best.

Hint: It's often helpful to have a small stream of water running in the line to wash the cuttings away while the

machine is in operation and after.

10. Be careful not to let the cutter get caught in the stoppage as you work through it. This can cause kinking

and breaking of the cable. When you feel the cable starting to twist in your hands, stop the machine and

pull back on the cable. This will free the cutter from the obstruction. Then allow the cable to move forward

slowly into the stoppage. Remember, no cutting takes place when the blades stop turning.

11. After the line has been opened, return the cable to the drum with the motor turning forward. This is

important to prevent the cable from tangling in the drum or in the line.

Caution: Do not use reverse to pull the cable out of the drain. Always run the machine in forward, whether

you are feeding the cable into the line or pulling it out. Use reverse only to release the cable should it become

caught in the line.

12. When the cutting tool is near the drain opening, take your foot off the pedal to stop drum rotation. Never

retract the cutting tool from drain while cable is rotating. The cable could whip and cause serious injury.

SPECIAL OPERATIONS

IF CABLE GETS CAUGHT IN LINE

The motor can be reversed to free cable if it gets caught in the line. Use the following procedure:

1. Move the toggle switch on motor to reverse position.

2. Pull the cable out of the drain while the drum is rotating in reverse.

3. When the cable has been freed, move the toggle switch to the forward position.

Note: Do not run motor in reverse for more than a few seconds at a time since this could cause tangling in the

drum or kinking.

IF CABLE TANGLES IN DRUM

This is caused by using too much pressure when feeding the cable or by feeding the cable while running the

machine in reverse. To untangle cable, rotate drum in opposite direction. This will usually get the cable to lie

in the drum properly.

If cable has become severely tangled, which shouldn’t occur if used properly, it can be straightened out by

removing the distributor tube from the drum. To do this:

1. Loosen the four bolts that hold the distributor tube cone on the front of the drum.

2. Pull the cone and distributor tube forward, then pull the tangled portion of the cable out of drum.

3. After the cable has been straightened out, slide the distributor tube and cone back along the cable until it

can be repositioned and bolted to the front of the drum.

4. Then, push the excess cable back into the drum.

HOW TO REMOVE DRUM FROM MACHINE

1. Loosen front post knob and swing Power Cable Feed out of the way.

2. Push down on the spring-loaded motor and slide the V-Belt off the back of the drum.

3. Reach behind the drum and locate the drum-retaining latch. Pull the latch to release the drum shaft, then

pull the drum forward off of the machine.

4. To install the drum, simply slide drum onto machine. The latch will lock automatically.

5. Remove the belt guard by loosening retaining knob on top. Position the V-Belt around the drum, then

press down on the motor and slip V-belt onto the pulley. Be sure to reattach the belt guard.

6. Reposition the Power Cable Feed and tighten knob at base of front post.

HOW TO INSTALL 1/2" AND 3/8" CABLES IN DRUM

To install cable in the drum, simply connect the male end of the cable to the drum connecting cable, which is

already attached to the drum. Then remove the drum V-Belt and turn the drum clockwise, while pushing the

cable into the drum.

Note: The cable should lay in the drum in a clockwise direction.

ACCESSORIES

HOW TO USE J-DRUM (OPTIONAL)

The J-Drum holds 50 feet of 1/4” or 5/16” cable to be used when you need to clear smaller

1-1/4” to 2” lines. These cables have a basin plug head that can be spun through most strainer crossbars.

(See Cable Application Chart—Table 1)

1. To install cable, open chuck jaws fully so that cable will pass through easily.

2. Slide the back end of the cable (opposite to the end with basin head) through spout and into the drum.

The cable will be easier to install if you bend the last inch of cable at a 45-degree angle.

3. When working through difficult stoppages or tight bends, tighten the chuck to provide more torque and to

prevent the cable from tangling in the drum.

4. Clean and lubricate chuck regularly to prevent corrosion.

HOW TO USE DUAL-DRUM (OPTIONAL)

The Dual-Drum holds two different diameter cables at the same time. Inner and outer drum compartments

protect the cable from tangling. You can easily switch from 1/4” to 5/16” or 3/8” cables without removing either

one from the drum.

1. Install 1/4” cable into the Dual-Drum by sliding the back end of the cable (opposite to end with basin

head) through spout and into the inner drum. The cable will be easier to install if you bend the last

inch of cable at a 45-degree angle.

2. Install the 5/16” or 3/8” cable into the outer drum by sliding the back end of the cable (opposite to the

end with the Female connector) through the spout. Reach one hand into the drum through one of the

three ports in the face of the drum and pull the cable end to the left side of the outer drum. Then push

another two feet of cable into the drum while pulling the cable downward to form a loop. The cable

should lay in the drum in a clockwise direction.

Note: Use HE cables only in Dual-Drum—not EM cables.

3. Select the appropriate cable for the line you are working on. (See Cable Application Chart—Table 1)

If a 1/4” cable is required, reach into the Dual-Drum and pull the cable out of the inner drum and

through the spout. If a larger cable is required, slide 1/4” cable back though spout, then reach into the

drum and pull the 5/16” or 3/8” cable from the outer drum through the spout.

4. Each of the cables can be “chucked” in place to provide more torque by pressing the knurled knob against

the spring and tightening it against the cable.

MAINTENANCE

To keep your machine operating smoothly, it is essential that all bearings and distributor tube bushings be

lubricated. Oiling moving parts is particularly important where machine comes in contact with sand, grit and

other abrasive material.

CABLE MAINTENANCE

To get maximum service from your cables, be sure that they are clean and well oiled. This not only provides

running lubrication but greatly extends the life of the cables as well. Some users periodically pour oil directly

into the drum. Then, as the drum turns, the cables get complete lubrication. Our SNAKE OIL is ideally suited

for this purpose, since it not only lubricates the cables, it disinfects and deodorizes them as well.

FEED MAINTENANCE

Keep feed free of excessive soil and grit. It is recommended that the feed be flushed with fresh water followed

by a light oiling of the moving parts. No disassembly is normally required. Failure to feed can usually be

traced to the following possibilities:

DIRT ACCUMULATION: Over time, dirt can harden enough to stop roller rotation. Flushing with water followed

by liberal oiling can usually restore function. If disassembly is required, proceed as follows:

1. Remove the feed tension knob, springs and spring plunger. Note the positioning of these parts to ease re-

assembly. The top roller can now be removed.

2. Remove the snap rings and thrust washers from the bottom housing cylinders. The bottom rollers can now

be removed.

3. Re-assembly is done in reverse order.

DAMAGED ROLLER: Excessive use may wear a roller to the point of failure. It is recommended that all three

rollers be replaced at the same time (Cat # PO-MR-703).

TANGLED CABLE: If a cable loops over itself in the drum, it will not feed properly. Remove and reload the

cable by hand to restore function. If the cable kinks, it is evidence of abuse and results from the use of too

much pressure or use of the wrong size cable for the line. Do not force the cable—Let the cutter do the work.
