GENERAL POWER TOOL SAFETY WARNINGS

Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE.

*The text used in the general power tool safety warnings section of this manual is as required from the applicable UL/CSA standard. This section contains general safety practices for many different types of power tools. Not every precaution applies to every tool. And some do not apply to this tool.

Work Area Safety

  1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
  2. 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.
  3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical Safety

  1. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
  2. Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an in-creased risk of electric shock if your body is earthed or grounded.
  3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
  4. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
  5. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
  6. If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.

Personal Safety

  1. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
  2. Use personal protective equipment. Always wear eye protec-tion. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate condi-tions will reduce personal injuries.
  3. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or BATTERY pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
  4. Remove any adjusting key or wrench before turning the pow-er tool ON. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
  5. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
  6. Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
  7. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
  8. Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

Power Tool Use and Care

  1. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
  2. Do not use the power tool if the switch does not turn it ON and OFF. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
  3. Disconnect the plug from the power source and/or remove the BATTERY pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
  4. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instruc-tions to operate the power tool. Power tools are dangerous in the hands of untrained users.
  5. Maintain power tools and accessories. Check for misalign-ment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many acci-dents are caused by poorly maintained power tools.
  6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
  7. Use the power tool, accessories and tool bits etc. in accord-ance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a haz-ardous situation.
  8. Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

Service

  1. Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

SPECIFIC SAFETY INFORMATION

WARNING

This section contains important safety information that is specif-ic to this tool.
Read these precautions carefully before using this drain cleaning machine to reduce the risk of electrical shock or other serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE.

Keep this manual with machine for use by operator.

Drain Cleaning Machine Safety

  1. Before using the tool, test the ground fault circuit interrupter (GFCI) provided with the supply cord to insure it is operating correctly. A properly operating GFCI reduces the risk of electrical shock.
  2. Only use extension cords that are protected by a GFCI. The GFCI on the machine power cord will not prevent electrical shock from the extension cords.
  3. Only grasp the rotating cable with gloves recommended by the manufacturer. Latex or loose fitting gloves or rags can be-come wrapped around the cable and may result in serious person-al injury.
  4. Do not allow the cutter to stop turning while the cable is turn-ing. This can overstress the cable and may cause twisting, kinking or breaking of the cable and may result in serious personal injury.
  5. One person must control both the cable and the switch. If the cutter stops rotating, the operator must be able to turn the tool off to prevent the cable from twisting, kinking and breaking.
  6. Use latex or rubber gloves inside the gloves recommended by the manufacturer, goggles, face shields, protective cloth-ing, and respirator when chemicals, bacteria or other toxic or infectious substances are suspected to be in a drain line. Drains may contain chemicals, bacteria and other substances that may cause burns, be toxic or infectious or may result in other seri-ous personal injury.
  7. Practice good hygiene. Do not eat or smoke while handling or operating the tool. After handling or operating drain cleaning equipment, use hot, soapy water to wash hands and other body parts exposed to drain contents. This will help reduce the risk of health hazards due to exposure to toxic or infectious materi-al.
  8. Only use the drain cleaner for the recommended drain sizes. Using the wrong size drain cleaner can lead to twisting, kinking or breaking of the cable and may result in personal injury.

Specific Safety Information for Flexi-Rooter

  1. Keep a glove covered hand on the flexible shaft whenever the machine is running. This provides better control of the shaft and helps prevent twisting, kinking, and breaking of the shaft and reduces the risk of injury.
  2. Keep hands and fingers clear of spinning chains and cutters. May cause serious injury.
  3. Never operate machine with slip clutch cover removed. Fin-gers can get caught.
  4. Do not overstress cables. Keep a leather-gloved hand on the cable for control when machine is running. Overstressing the cables because of an obstruction may cause twisting, kinking, or breaking of the cable and may result in injury.
  5. Place the machine at a distance not greater than three feet (1m) from the drain opening. Greater distances can result in cable twisting or kinking.
  6. Before operating machine, insert cutter into pipe. Allowing the cutter to spin outside the pipe can be very dangerous.
  7. 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.
  8. Do not operate machine while standing in water. Will increase risk of electric shock.
  9. Only use this tool in the application for which it was de-signed. Follow the instructions on the proper use of the ma-chine. Other uses or modifying the drain cleaner for other appli-cations may increase risk of injury.
  10. 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 (kinked or broken) cables with genuine GENERAL replacement cables.
  11. When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manu-al. Use of unauthorized parts or failure to follow Maintenance instructions may create a risk of electric shock or 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, DO NOT USE THE MACHINE 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 run-ning, or if the operator experiences a mild shock, DO NOT USE THE MACHINE! Tag the machine out of service and take it to a motor repair center or return it to the factory for repairs.
    THE SECTION OF CORD BETWEEN THE WALL PLUG AND THE GFCI IS NOT IN THE PROTECTED CIRCUIT.

CAUTION: Do not operate machine if warning labels are missing or illegible.

What is Flexible Shaft Technology?

Flexible shaft technology is faster and more thorough than traditional drain cleaners. Flexible shaft spins more than 10 times faster than drum machines. At speeds of 2000 RPM or more, the cutters quickly grind up stoppages and scour the walls of the pipe. The flexible shaft is safely protected inside a sheath so it’s easy to handle – no spinning drums.

  • Integral Variable Speed Motor
    The integral variable speed motor lets you adjust the speed from 0 – 2400 rpm. With the foot pedal you have both hands free to safely guide the flexible shaft into the line.

  • Stronger, Stiffer Flexible Shaft
    General’s shaft is flexible enough to get through 2 inch lines, yet tough strong enough to cut roots in 4 inch drain lines up to 75 feet down the line.

  • Field Repairable Flexible Shaft
    Free cutting flexible shaft is easily field repairable using an abrasive cutoff wheel or band saw.

  • Non-Marring Flexible Shaft Coupler
    General’s unique non-marring flexible shaft coupler securely clamps onto the flexible shaft without causing damage to the shaft. Patent pending.

  • Safety Slip Clutch
    When properly adjusted, the safety slip clutch protects you from injury and the shaft from damage. It will slip if the cutter is caught or being forced into the stoppage too quickly.

  • Easily Maneuverable Frame
    Durable metal frame includes 10” wheels and folding handle, and easily fits through narrow doorways.

  • Two-Part Cutter Array
    General’s Innovative, cutter system combines the unique ClogChop-per® with Carbide-Tipped Chain Cutters to make a formidable combi-nation. Together, they are capable of boring through tough stoppages and scale, shredding obstructions and scouring pipe walls clean.

    General-100-Flexi-Rooter-Drain-Cleaners-fig-6

OPERATION

SET-UP

MAKE SURE THE MOTOR SWITCH IS IN THE ‘OFF’ POSITION!

  1. Place the machine as close to the drain opening as possible to help prevent the shaft from whipping and kinking.
  2. Always lay the machine down horizontally on the floor during operation.
  3. Position the air 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.
  4. Be sure the power switch is in the OFF position.
  5. Select the proper cutter for your application and secure it to the shaft. See Cutter Application Chart and appropriate attachment section.

OPERATION

Note: It is helpful to use your sewer inspection camera as the same time to help position the cutter at the stoppage and to monitor the progress of the operation. Be sure to keep the camera at least
18” (.5m) back from the cutter to prevent damage to the camera in-spection system.
Note: The machine should always be operated with the motor set to FORWARD rotation. If necessary, the motor can be put into reverse by turning the speed knob to release the trigger switch and pushing the motor direction button toward the reel plate.

BEFORE OPEATING THE MACHINE, INSERT THE CUTTER INTO THE PIPE.
ALLOWING THE CUTTER TO SPIN OUTSIDE THE PIPE CAN BE VERY DANGEROUS.

  1. Release the brake at the center of the reel.

  2. Before stepping on the foot pedal, pull the flexible shaft and cutter from the reel and slide it into the drain at least 12” down the line. Allowing the cutter to spin outside the pipe can be very dangerous.

  3. Make sure the motor is set to FORWARD rotation. Set the motor rotation speed by adjusting the speed knob on the motor clamp. The no load speed range is from 0 – 2400 rpm.

  4. Turn the power switch ON. The switch will light up.

  5. While firmly holding the flexible shaft with both gloved hands, guide the shaft manually down the line.
    Note: It is not recommended to continuously run the machine. Step on the foot pedal only when you encounter an obstruction and when trying to navigate bends and seams in the pipe.

  6. Guide the flexible shaft into the line with a firm even pressure. Do not force the flexible shaft. Let the cutter do the work. You won’t get the job done any faster and you could damage the shaft.

  7. For the best cleaning operation, the rotation speed should be between 1000 and 2200 rpm depending on the resistance in the line and type of stoppage. It is recommended to slow the rotation speed down to help the cutter get around tight bends. Adjust the speed to the level that works best for you.
    OPERATING THE MACHINE AT EXCESSIVE SPEEDS FOR LONG PERIODS OF TIME WILL PREMATURELY WEAR DOWN TOOLING AND POSSIBLY DAMAGE THE PIPE

  8. If you are having trouble getting around a tight bend, push and rotate the shaft at the same time at low speed. The shaft is flexi-ble enough to negotiate several 90 degree bends.

  9. It is helpful to push and release the foot pedal to help the chain cutter navigate bends and seams in the pipe.

  10. Use the ClogChopper penetrating head on its own or in combina-tion with the chain cutters to punch through a complete blockage. Then push and pull the spinning chain cutter though the area to thoroughly clean the line. Use a sewer camera to monitor and inspect your work.

  11. If descaling the pipe, push the chain cutter past the area to be cleaned, then pull the flexible shaft back though the area as you flush the line with water for a more thorough cleaning job.
    MOVE THE SHAFT AND CUTTER BACK AND FORTH CONTINUOUSLY WHILE IN OPERATION.
    LEAVING THE SHAFT TO SPIN IN THE SAME PLACE FOR LONG PERIODS OF TIME COULD DAMAGE THE OUTER SHEATH.

  12. After the job is complete, pull the flexible shaft out of the pipe and wipe off the sheath as you guide it into the reel. A disinfectant spray can be applied to the cloth or sprayed directly onto the sheath to help reduce contaminates. Be sure to inspect the flexible shaft and sheath for wear and damage as you and re-turned to the reel. Then use the reel brake to lock the reel and keep it from rotating.
    Hint: Running water into the line while cleaning will help to flush away debris and keep the shaft and tooling cooler by reducing heat generated by friction.
    THE SAFETY SLIP CLUTCH IS THERE TO PROTECT YOU FROM INJURY AND THE SHAFT FROM DAMAGE. IT WILL SLIP IF THE CUTTER IS CAUGHT OR BEING FORCED INTO THE STOPPAGE TOO QUICKLY. GO SLOWLY AND LET THE CUTTER DO THE WORK. IF THE FLEXIBLE SHAFT BEGINS TO BUCK OR TWIST, STOP BY TAKING YOUR FOOT OFF OF THE PEDAL. SEE THE CLUTCH ADJUSTMENT SECTION IN MAINTENANCE SECTION TO MAKE ANY NECESSARY ADJUSTMENTS TO THE CLUTCH.

ATTACHING FLEXIBLE SHAFT EXTENSIONS

  1. Make sure the machine is turned off and unplugged before attach-ing any accessories.
  2. Inspect the extension for damage and make any necessary re-pairs. DO NOT use a damaged shaft, leader or extension.
  3. Loosen the screws on the leader side of the shaft coupler so that the leader can be inserted.
  4. Insert the flexible shaft extension into the flexible shaft coupler making sure it extends to the midpoint of the coupler and tighten the screws to approximately 41 lb.-in. of torque.
    CHECK THAT THE FLEXIBLE SHAFT COUPLER SCREWS ARE TIGHT BEFORE EACH USE. USE THE SUPPLIED LOCTITE® ANY TIME SCREWS ARE TIGHT-ENED ONTO A LEADER. NEVER USE PERMANENT THREAD LOCKER. SEE MANUFACTURER’S WEBSITE FOR PROPER USE.

MAINTENANCE

DISCONNECT MACHINE FROM POWER SOURCE BEFORE PERFORMING MAINTENANCE!

Flexible Shaft Inspection
Carefully inspect the flexible shaft and sheath before each use to ensure that there are no signs of wear or damage. Take special note to inspect the area shown in Figure 5B for damaged wires. If the shaft or sheath is damaged or worn, repair the shaft before attaching a cutter (See How to Repair Flexible Shaft), or replace the entire shaft as needed. Inspect the shaft more frequently when used in tight bends.

FIGURE 5B

Slip Clutch Adjustment
The Safety Slip Cutch is factory set for optimum performance. If you need to adjust the clutch, follow these steps:

  1. Make sure the machine is turning off and unplugged before mak-ing any adjustments.
  2. Remove the slip clutch cover with the machine in the upright posi-tion. Set aside the 4 screws, washers, and lock nuts to be rein-stalled later.
  3. Lay the machine down and locate the standard hex nut and thin hex nut on the slip clutch stem.
  4. While holding the standard hex nut in place, loosen the thin hex nut.
  5. Hold the body of the slip clutch in place and tighten the standard nut to increase the torque at which the clutch will slip and loosen the standard nut to decrease the torque at which the clutch will slip. The slip clutch should be set at a maximum of 65 lb.-in. of torque.
  6. Once the desired torque is achieved, hold the standard nut in place and tighten the thin nut to lock it in place.
  7. Stand the machine upright and reinstall the slip clutch cover.
