Frequently Asked Questions - FlexShaft K9306 RIDGID

What type of pipes can this drain cleaner clean?

The RIDGID FlexShaft K9306 is designed for cleaning and descaling drain pipes of 3 to 6 inches (75 to 150 mm) in diameter, up to 125 feet (38 m) in length.

How to install the drain cleaner before use?

Place the unit within 4 feet (1.2 m) of the access point, on a flat and dry surface. Extend the telescopic handle, pull out about 5 feet of cable, and insert the cleaning chain at least 1 foot into the pipe. Plug into a grounded outlet and test the ground fault circuit interrupter.

What safety precautions are essential?

Always wear safety glasses and appropriate gloves (latex inner gloves recommended). Keep a gloved hand on the rotating cable. Do not let the chain spin outside the pipe. Use the ground fault circuit interrupter and never work with your feet in water.

How to mount and adjust the cleaning chain?

Choose the chain suitable for the diameter. Mount it with a collet spacer and a stop sleeve limiting the exposed cable to 1/4 inch (6 mm). Tighten the locking screws with the supplied 3 mm Allen key.

What to do if the cable gets stuck in the pipe?

Release the foot pedal. Set the switch to REV position and briefly press the pedal to reverse rotation. Gently pull the cable to free it. Do not force it.

How to maintain the drain cleaner?

After each use, wipe the cable sheath. Clean the unit with warm soapy water. Check the motor brushes every 6 months and replace them if worn to less than 1/2 inch (13 mm). Damaged cable must be replaced.

Can the drain cleaner be used with an inspection camera?

Yes, the FlexShaft is particularly suitable for camera tracking. Keep the camera at least 1.5 feet (50 cm) behind the cleaning chain and avoid any contact with the rotating chain.

What does the flashing LED light mean?

The torque limiter LED flashes when the motor draws too much current. Release the pedal to reset. If the light stays on steady, the motor has overheated: unplug and let cool for 15 minutes.

How to replace the cable?

Remove the chain, loosen the front cover screws, disconnect the cable coupler, then remove the old cable. Install the new cable by aligning the sheath in the window (between the marks). Tighten the clamps and reassemble the cover.

Where to find spare parts and accessories?

Use only RIDGID parts. Consult the RIDGID online catalog or contact an authorized repairer. Accessories include cleaning chains (carbide or standard), brushes, penetrating heads, FlexShaft lubricant, and replacement sheaths.

General Power Tool Safety Warnings\*

WARNING

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 term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Work Area Safety

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explo-

sive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

- Keep children and by-standers away while a power tool. Distractions can cause you to lose control.

Electrical Safety

• 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.
• Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electrical shock if your body is earthed or grounded.
• Do not expose power tools to rain or

wet conditions. Water entering a power tool will increase the risk of electrical shock.

• 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.
• 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.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE!

Keep this manual with machine for use by the operator.

FlexShaft™ Drain Cleaning Machine Safety

• Before using the tool, test the ground fault circuit interrupter (GFCI) provided with the power supply cord to insure it is operating correctly. A properly operating GFCI reduces the risk of electrical shock.
• Only use extension cords that are protected by a GFCI. The GFCI on the machine power cord will not prevent electrical shock from extension cords.
• Only grasp the rotating cable with gloves recommended by the manufacturer. Latex or loose fitting gloves or rags can become wrapped around the cable and may result in serious personal injury.

• Do not allow the cutter to stop turning while the cable is turning. This can overstress the cable and may cause twisting, kinking or breaking of the cable and may result in serious personal injury.

• 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.

• Use latex or rubber gloves inside the gloves recommended by the manufacturer, goggles, face shields, protective clothing, 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 serious personal injury.
• 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 material.
• Only use the Drain Cleaning Machine 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.
• Keep glove covered hand on the cable assembly whenever the FlexShaft Machine is running. This provides better control of the cable and helps prevent twisting, kinking and breaking of the cable and reduces the risk of injury.
• Position machine cable outlet within 4' (1.2 m) of the drain inlet or properly support exposed cable assembly when the distance exceeds 4' (1.2 m). Greater distances can cause control problems leading to twisting, kinking or breaking of the cable. Twisting, kinking or breaking cable may cause striking or crushing injuries.
• Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts. Loose clothing, jewelry or hair can be caught in moving parts.
• Do not operate this machine if operator or machine is standing in water. Operating machine while in water increases the risk of electrical shock.
• Do not use if there is the risk of contact with other utilities (such as natural gas or electric) during operation. Visual

inspection of the drain with a camera is a good practice. Crossbores, improperly placed utilities and damaged drains could allow the chain knocker to contact and damage the utility. This could cause electrical shock, gas leaks, fire, explosion or other serious damage or injury.

• Any condition which may prevent safe and normal operation.

If any problems are found, do not use the drain cleaning machine until the problems have been repaired.

1. Clean any debris from the cable assembly and chain knockers. Inspect sheath for wear and damage. There should not be any cuts, kinks, breaks or excessive wear. Inspect the cable near the chain knocker. Cable assemblies should not be bent or deformed. Cable strands should be tight to one another without separation. Inspect chain knocker for damaged or lost carbide cutting tips (if equipped) and wear of the chain itself. If chain links are worn more than 14 through or damaged, replace the chain knocker. Replace worn and damaged equipment before using drain cleaning machine.

Confirm that the chain knocker is properly set up and is secure on the cable.

1. Inspect and maintain any other equipment being used per its instructions to make sure it is functioning properly.

2. Make sure that the REV/O-OFF/FOR switch is set to the O-OFF position.

3. With dry hands, plug cord into properly grounded outlet. Test the GFCI provided in the electrical cord to ensure that it is operating correctly. Depress the GFCI TEST button -the machine should not operate. Depress the RESET button – the machine should operate. If GFCI is not functioning properly, unplug the cord and do not use the drain cleaning machine until the GFCI has been repaired.

4. With the inspection complete, with dry hands, unplug the machine.

Machine and Work Area Set-up

WARNING

Three black-and-white icons: a circular eye with glasses, a hand holding a rope, and a stick figure running with a briefcase (no text or symbols)

Set up the Drain Cleaning Machine and work area according to these procedures to reduce the risk of injury from electric shock, fire, machine tipping, twisted or broken cables, chemical burns, infections and other causes, and prevent machine damage.

Always wear safety glasses and other appropriate protective equipment when setting up your Drain Cleaning Machine.

1. Check for an appropriate work area. Operate in a clear level, stable, dry location. Do not use the Drain Cleaning Machine while standing in water.

2. Inspect the drain to be cleaned. If possible, determine the access point(s) to the drain, the size(s), length(s), and material(s) of the drain, distance to mainlines, the nature of the blockage, presence of drain cleaning chemicals or other chemicals, etc.

If chemicals are present in the drain, it is important to understand the specific safety measures required to work around those chemicals. Contact the chemical manufacturer for required information. Confirm no other utilities are present in the drain or area to reduce the risk of damage. Visual inspection of the drain with a camera is a good practice.

If needed, remove fixture (water closet, etc.) to allow access to drain. Do not run the chain knocker in a fixture. This could damage the FlexShaft Machine or the fixture.

1. Determine the correct equipment for the application. See Specifications. Drain Cleaning Machines for other applications can be found by consulting the Ridge Tool Catalog, online at RIDGID.com.

2. Make sure all equipment has been properly inspected.

3. If needed, place protective covers in the work area. The drain cleaning process can be messy.

4. Transport the drain cleaning machine to the work area along a clear path. Adjust handle if necessary (Figure 4). Move handle latches together and move telescoping handle to desired position. Confirm that the handle latches engage and the handle is securely held in position. If handle is moved past latch holes, the handle buttons will prevent the handle from pulling out. If this occurs, depress buttons to move handle.

Telescoping Handle Handle Button Handle Latches

Figure 4 – Adjusting Telescoping Handle

1. Place the Drain Cleaning Machine as shown in Figure 5. Machine should sit squarely and firmly on the ground.

2. Position the Drain Cleaning Machine so that the cable outlet is within 4' (1.2 m) of the drain access. Greater distances from the drain access increases the risk of the cable assembly twisting or kinking. If the FlexShaft Machine cannot be placed with the cable outlet within 4' (1.2 m) of the drain access, extend the drain access with similar sized pipe and fittings (see Figure 5). Improper cable assembly support can allow the cable to kink and twist and can damage the cable or injure the operator. Extending the drain back to the Drain Cleaning Machine also makes it easier to feed cable assembly into drain.

Figure 5 – Example of Extending Drain Access to within 4' (1.2 m) of Machine Cable Outlet

1. Unclamp the chain knocker and pull approximately 5' (1.5 m) of cable assembly out of the machine.

2. Mark the sheath to indicate when the chain knocker is approaching the drain opening when withdrawn. This can be done with tape. This reduces the risk of the chain knockers coming out of the drain and whipping around. The distance depends on the configuration of the drain, but should be at least 5' (1.5 m) from the chain knocker.

3. Ensure chain knocker is properly installed (see Installing/Adjusting Chain Knocker).

4. Insert chain knocker end at least 1' (0.3 m) into drain.

5. Evaluate the work area and determine if any barriers are needed to keep bystanders away from the drain cleaning machine and work area. The drain cleaning process can be messy, and bystanders can distract the operator.

6. Position the foot switch for easy accessibility. You must be able to hold and control the cable, control the foot switch, and reach the REV/O-OFF/FOR switch.

7. Confirm that the REV/O-OFF/FOR switch is in the O-OFF position.

8. Run the cord along a clear path. With dry hands, plug the drain cleaner into a properly grounded outlet. Some GFCIs may need to be reset every time they are plugged in. Reset GFCI if needed. Keep all connections dry and off the ground. If the power cord is not long enough, use an extension cord that:

9. Is in good condition.

10. Has a plug similar to that supplied on the drain cleaner.
11. Is rated for outdoor use and contains a W or W-A in the cord designation (i.e. SOW), or complies with H05VV-F, H05RN-F types or IEC type design (60227 IEC 53, 60245 IEC 57).
12. Has sufficient wire size. For extension cords up to 50' (15,2 m) long use 16 AWG (1,5 mm²) or heavier. For extension cords 50'-100' (15,2 m – 30,5 m) long use 14 AWG (2,5 mm²) or heavier.

When using an extension cord, the GFCI on the drain cleaner does not protect the extension cord. If the outlet is not GFCI protected, it is advisable to use a plug in type GFCI between the outlet and the extension cord to reduce the risk of shock if there is a fault in the extension cord.

1. Move the REV/O-OFF/FOR Switch to the O-OFF position, and with dry hands unplug the machine.

Installing/Adjusting Chain Knocker

1. Select proper chain knocker for the conditions.

Chain knockers are sized based on collar inside diameter and are designed for specific cable sizes. 3/8" chain knockers are used on 3/8" cable, etc. Do not use a larger size chain knocker on a smaller cable (for instance 1/2" on 3/8"). See Figure 6 and Collar Distance Chart.

Chain knockers without carbide cutting tips can be used in common pipe types. These chain knockers work well in grease and similar blockages.

Chain knockers with carbide cutting tips are used for removing scale from the inside of the pipe and can be used for roots. Carbide cutting tips are used for aggressive cleaning and could damage pipe, especially softer materials (such as plastics and Orangeburg), thin walled pipe, or if the chain knocker is kept in one position for an extended time.

Do not use chain knockers for cleaning in glass, ceramic, porcelain or similar material fixtures or pipes. They could be damaged.

1. Figure 7 shows a schematic of proper chain knocker installation and adjustment.

There are two key points when installing/adjusting chain knockers.

Collar Distance: Set the chain knocker collars the correct distance apart (“Collar Distance”) to allow the chains to spread an appropriate amount when rotated to clean the pipe walls. Collar Distance varies based on cable size and pipe diameter, and is generally set using a spacer made from sheath (“Collar Spacer”). If additional flexibility is required to navigate a bend, the collar spacer can be removed and the collar distance can be set with a tape measure. Operating without a collar spacer makes it more likely for the cable to flip over in use and be damaged. Do not operate carbide cutters without a collar spacer to reduce risk of cable damage.

Exposed Cable: Minimize the amount of exposed cable (cable not covered by sheath). The more exposed cable there is, the more likely the cable will flip over in use and be damaged. Exposed cable should be limited to no more than 14 " (6 mm), and is set with a bushing made from sheath ("Knocker Bushing").

Sheath is supplied with the drain cleaner and is available as a service part to allow configuration as needed for your specific application. Only use RIDGID FlexShaft Drain Cleaner sheath of the correct size for the cable. Any time sheath is cut, it should be cut cleanly and squarely. Do not damage the cable when cutting the sheath.

1. Chain knockers are retained to the cable with set screws that use a supplied 3 mm hex key. Loosen set screws and remove chain knocker, spacer and bushing from cable.

2. With no knocker installed, hold cable end away from your body or others. Run machine in REVERSE for 5 seconds to maximize exposed cable. Place switch in O-OFF position and unplug machine.

Hold sheath and pull on cable to remove slack and expose maximum amount of cable.

1. Inspect the sheath end for damage or wear. The sheath end should be square and clean. If needed, the sheath end can be trimmed slightly.

2. If needed, cut a section of sheath to use as the collar spacer to the appropriate size (See Collar Distance Chart).

Collar distance can be modified to your preference for the specific pipe/application. As collar distance increases, the diameter of the chains decreases, and vice versa. Improperly set collar distance can reduce the efficiency of pipe cleaning.

1. Test fit the chain knocker, knocker bushing and collar spacer on the cable as shown in Figure 7. Chains should be straight – do not assemble with chains twisted. To prevent excessive cable end wear, cable end should be flush with the end of the collar.

Check length of exposed cable. To reduce the risk of cable flip over and damage, exposed cable cannot exceed 14 " (6 mm). If needed, cut a knocker bushing from sheath to limit exposed cable. Always use a knocker bushing to reduce wear on the sheath end.

1. With the chain knocker correctly installed on the cable as shown in Figure 7, use the supplied hex wrench to securely tighten the collar set screws. If the set screws are not secure, the chain knocker could slip and damage the cable or be lost down the drain.

Installing Brushes

Brushes are available for various uses, such

as cleaning the inside of the pipe, centering the chain knocker in the pipe and spreading lining compound. See the specific brush information for the types of uses it is appropriate for.

Brushes can be assembled in a variety of configurations, with some options shown in Figure 8.

Brush Only Brush with Securing Ring Centering Guide

Figure 8 – Example Brush Configurations

Installation of brushes is similar to the installation of chain knockers. The collar of the brush is placed over the cable and retained by securely tightening the set screws. When at the end of the cable, the cable end is flush with the brush collar. Brush securing rings are available to improve brush retention if set screws loosen in use.

As with chain knockers, minimize the amount of exposed cable (cable not covered by sheath). The more exposed cable there is, the more likely the cable will flip over in use and be damaged. Limit exposed cable to no more than 14 " (6 mm), set with a bushing made from sheath ("Knocker Bushing").

Installing Penetrating Head

Penetrating heads are available to help create a hole in a blockage to get the drain flowing and allow the chain knocker into an area. See Figure 9 for installation information.

Operating Instructions

WARNING

Always use safety glasses and gloves in good condition while handling or using. Use latex or rubber gloves, face shields, protective clothing, respirators or other appropriate protective equipment when chemicals, bacteria or other toxic or infectious substances are suspected to be present to reduce the risk of infections, burns or other serious personal injury.

Do not allow the chain knocker/end of cable to stop turning while cable assembly is turning. This can overstress the cable and may cause twisting, kinking or breaking of the cable assembly and may result in serious personal injury.

Keep a hand on the cable assembly whenever the FlexShaft Machine is running. This provides better control of the cable and helps prevent twisting, kinking and breaking of the cable and reduces the risk of injury.

Position the FlexShaft Machine cable outlet within 4' (1.2 m) of the drain inlet or properly support exposed cable assembly when the distance exceeds 4' (1.2 m). Greater distances can cause control problems leading to twisting, kinking or breaking of the cable. Twisting, kinking or breaking cable may cause striking or crushing injuries.

One person must control both the cable assembly and foot switch. If the cable stops rotating, the operator must be able to turn the tool OFF to prevent twisting, kinking and breaking of the cable and reduce the risk of injury.

Follow operating instructions to reduce the risk of injury from twisted or broken cable, cable ends whipping around, machine tipping, chemical burns, infections and other causes.

1. Make sure that machine and work area is properly set-up and that the work area is free of bystanders and other distractions.
2. Pull cable assembly from the machine and feed into drain. At least 1' (0.3 m) of cable must be in drain so that the chain knocker will not come out of the drain and whip around when the machine is started.

Directly route the cable assembly from the machine cable outlet to the drain opening, minimizing exposed cable and changes in direction. Do not tightly bend the cable assembly – this can increase the risk of twisting or breaking.

If using a camera to view the drain cleaning process, the camera can be fed in at the same time. Typically the cable assembly and the camera push rod can be gripped and advanced/retrieved at the same time. Keep the camera at least 1.5' (0.5 m) behind the chain knocker.

NOTICE Do not allow the spinning chain knocker to hit the camera head/push rod. It can damage it.

1. Assume a proper operating position to help maintain control of the cable assembly and machine (see Figure 10):
2. Be sure you can quickly release the foot switch.

3. Your gloved hands must be on the cable assembly to control and support as the cable assembly is fed into the drain and blockage.

4. Be sure that you have good balance, do not have to overreach, and cannot fall on machine, drain, etc.

5. You must be able to reach the REV/O-OFF/FOR switch.

This operating position will help to maintain control of the cable assembly and FlexShaft Machine.

4 (1.2 m) MAX.

Figure 10 – In Operating Position

1. Confirm that at least 1' (0.3 m) of cable assembly is in the drain.
2. Grasp the exposed cable assembly with both gloved hands equally spaced and pull 6"-12" (150mm - 300mm) of cable out of the drum so that there is a slight bow in the cable. Gloved hands must be on the cable to control and support the cable. Improper cable support can allow the cable to kink or twist and can damage the cable or injure the operator. Make sure that the cable outlet of the drain cleaner is within 4' (1.2 m) of the drain opening (Figure 10).
3. Move the REV/O-OFF/FOR switch to FOR (Forward) position.
4. Depress the foot switch to start the machine. There will be a slight delay before the cable starts to rotate. The person controlling the cable must also control the foot switch. Do not operate the drain cleaner with one person controlling the cable and another person controlling the foot switch. This can lead to twisting, kinking and breaking of the cable.
5. The FlexShaft Drain Cleaning Machine utilizes high rotational speed and low torque to clean drains. FlexShaft cable assemblies are more flexible than other types

of drain cleaning cables. The FlexShaft machine is best used by applying light pressure and slowly working the chain knocker into the blockage. It's important to let the speed of the chain knocker clean the drain – do not force chain knockers into blockages.

1. Advancing/Retrieving the Cable Assembly – FlexShaft Lubricant

In some cases it may be beneficial to apply RIDGID FlexShaft lubricant to the outside of the sheath when feeding the cable down the drain. This can make it easier to advance the cable assembly down the drain and allow greater cleaning distance. If doing so, place a clean towel with lubricant on it in the palm of the gloved hand used for advancing the cable assembly, and apply lubricant as feeding the cable assembly (Figure 11). Add lubricant to the towel as needed during the process. RIDGID FlexShaft markings are printed on the sheath every 5' (1.5 m) to aid in determining how much cable assembly has been fed from the machine.

Only use RIDGID FlexShaft lubricant. Other lubricants may not be appropriate for use in a drain and could contaminate the water.

When retrieving the cable assembly, it is good practice to use a towel to wipe dirt and debris from the cable sheath as it is pulled from the drain and fed back into the drum.

1. Rotating the Chain Knocker

Generally the chain knocker is rotated for cleaning while withdrawing the cable.

Only rotate the cable/chain knocker when the chain knocker is at least 1' in the drain. To rotate the cable, firmly grip the cable and depress the foot switch. The person controlling the cable assembly must also control the foot switch. Do not operate the machine with one person controlling the cable assembly and another person controlling the foot switch. Do not allow cable assembly to build up outside the drain, bow or curve. This can lead to twisting, kinking and breaking of the cable. At any time, release the foot switch to stop cable rotation. When clearing blockages, operate the cable at full speed for best cleaning. Do not force the chain knocker into blockages. Rotating the chain knocker in FORWARD or RE-

VERSE for a short time while advancing the cable assembly can help it negotiate the drain and blockages.

Figure 11 – Applying Lubricant to the Cable Sheath

1. Advance the cable assembly into the drain, generally not rotating. Grasp the sheath near where it exits the machine housing. Pull 6" to 12" (150 to 300 mm) of cable assembly out of the FlexShaft

Machine so that there is a slight bow in the cable. Gloved hand must be on cable assembly to control and support. Improper cable support can allow the cable assembly to kink or twist and can damage the cable or injure the operator. Feed the cable assembly into the drain (Figure 12, Step 1).

1. Continue to advance the cable assembly until the resistance is encountered. Carefully work the chain knocker through the blockage. Do not force the cable assembly – if the chain knocker cannot turn, it cannot clean the drain. Pay attention to how far the cable has gone. Do not overrun the cable into a larger drain. This can cause the cable to knot up or cause other damage (Figure 12, Step 2).

2. Once the drain is open, if possible, start a flow of water down the drain to flush the debris out of the line and help clean the cable assembly as it is retrieved. This can be done by turning on a faucet in the system or other methods. Pay attention to the water level, as the drain could plug again (Figure 12, Step 3).

3. With the chain knocker past the blockage/area to be cleaned and REV/O-OFF/FOR switch in FOR position, depress the

1. Advance the chain knocker (generally not rotating) to the area of the drain that needs cleaned.

2. If there is a blockage, pass the chain knock-er through the blockage.

3. If possible, start a flow of water through the drain to carry cuttings and debris away as the drain is cleaned.

1. Rotate the cable/chain knocker at full speed.

2. Continue to rotate knocker. Gradually withdraw the cable assembly so that the chain knocker can break up the blockage.

3. Continue to gradually withdraw the cable assembly while rotating so that the chain knocker can clean the walls of the drain.

Figure 12 – General Operating Steps

foot switch to rotate the chain knocker. Slowly pull the cable assembly from the drain, allowing the rotating chain knocker to clean the drain walls and break up the blockage (Figure 12, Steps 4 & 5). If the cable stops turning, do not continue operating the machine. This may cause the cable to twist and kink. At any time, release the foot switch to stop cable rotation. Rotating the cable in REVERSE can help clean the opposite side of the pipe.

Monitor the feedback from the feel of the cable assembly in your hand and the sound of the motor/knocker in the drain. It may be necessary to move the chain knocker out of the blockage to allow it to come back up to speed.

If the chain knocker becomes stuck, the electronic torque limiter will shut off the motor to reduce the likelihood of cable damage. The torque limiter LED will flash to indicate this. Release the foot switch to allow motor to restart. Place the REV/O-OFF/FOR switch to allow opposite rotation. Grasp the cable with both gloved hands, press the foot switch for several seconds and pull on the cable until it is free of the blockage. Repeat if necessary. In some cases, it may be possible to pull the cable assembly and the blockage out of the drain by hand. If this is done, be careful to not damage the cable assembly.

Place the REV/O-OFF/FOR switch in the FOR position and continue cleaning the drain.

NOTICE Do not allow the spinning chain knocker to hit the camera head/push rod. It can damage it.

1. Continue to clean the rest of the drain while retrieving the cable. Once the drain has been cleaned, retrieve the cable and feed back onto the drain cleaning machine. Pay close attention, as the cable may lodge in a blockage while being retracted (Figure 12, Step 6).
2. Watch for your sheath marking as the cable assembly is retrieved. Release the foot switch when the chain knocker nears drain opening. Do not pull the chain knocker from drain while it is rotating. The chain knocker can whip around and could cause serious injury.
3. If needed for complete cleaning, repeat the above procedure.
4. Pull any remaining cable assembly from the line by hand and push back into the drum. Prepare the machine for transport.

Using Machine With Brushes

Using the machine with a brush is similar to use with a chain knocker. Brushes are used for finer cleaning of the pipe, they are not used for blockage removal. Remove blockages and heavy debris with a chain knocker or other methods first. While chain knockers are most typically rotated while withdrawing the cable from the drain, brushes are typically used while advancing the cable. This is because the brushes typically fill the drain diameter and push debris in front of them. See Figure 13 for general steps.

Brushes can also be used in conjunction with chain knockers such as centering devices or for combined cleaning. Usage depends on the exact circumstances and is left to the judgment of the user.

1. Advance the brush (generally not rotating) into the drain.
2. When the area to be cleaned is reached, if possible, start a flow of water through the drain to carry debris away during cleaning.
3. Rotate the cable/brush at full speed and gradually advance the cable into the drain to clean the walls as desired.

⚠ WARNING The Drain Cleaning Machine must be kept dry and indoors or well covered if kept outdoors. Store the machine in a locked area that is out of reach of children and people unfamiliar with drain cleaning machines. This machine can cause serious injury in the hands of untrained users.

Maintenance Instructions

WARNING

REV/O-OFF/FOR switch should be O-OFF and machine unplugged before performing any maintenance.

Always wear safety glasses and other appropriate protective equipment when performing any maintenance.

Cleaning

It is good practice to use a towel to wipe dirt and debris from the sheath as the cable assembly is pulled from the drain and fed back into the drum. This will help to keep the drum clean and reduce the likelihood of the cable assembly sticking in the drum. If needed, cable assembly can be pulled from the machine and the housing opened for flushing/cleaning.

Clean the machine as needed with hot soapy water and/or mild disinfectants.

Do not submerge or flush the machine with water. Do not allow water to enter motor or other electrical components. Make sure unit is completely dry before plugging in and using.

Lubrication

The FlexShaft Drain Cleaning Machines are lubricated for life from the factory.

Cable Re-termination

The FlexShaft cable cannot be shortened or re-terminated. If the cable is damaged, it must be replaced. Do not use a damaged cable.

Cable Assembly Replacement

1. Remove chain knocker from cable assembly.
2. Use a 4 mm hex wrench to loosen the front cover fasteners (they are retained to the cover and frame). Lift the cover and unplug the motor wire connector (Figure 18). Feed cable through bushing into machine. Remove the front cover.

1. Securely tighten all clamp fasteners.

2. Confirm end of sheath is between the lines in the viewport. Securely tighten the sheath clamp screws.

3. Feed the cable into the drum channel.

4. Feed the end of the cable through the cable bushing in the front cover and securely install the front cover.

5. With no knocker installed, hold cable end away from your body or others. Run machine in REVERSE for 5 seconds to maximize exposed cable. Place switch in O-OFF position and unplug machine.

If there is no cable exposed, cut back sheath to expose 1"-2" (25 - 50 mm) of cable. Hold sheath and pull on cable to remove slack and expose the maximum amount of cable. Cut the sheath back to expose 7 3/4" (197 mm) of cable measured from the end of the cable.

Go to Installing/Adjusting the Chain Knocker section, step 5 to complete chain knocker installation.

Motor Brush Inspection/Change

Brushes should be inspected every 6 months and changed when shorter than 12 " (13 mm).

1. See Cable Assembly Replacement, step 2 to remove cover.
2. Use a screwdriver to remove the brush cover, Figure 21. Remove brush and inspect. If there are any signs of damage or shorter than 12 " (13 mm), replace brushes.
3. Reverse process to reassemble.
4. Place chain knocker in drain and allow to run 15 minutes in FORWARD and REVERSE, to break in brushes.

Electronic Torque Limiter/Motor Thermal Overload

The machine is equipped with an Electronic Torque Limiter/Motor Thermal Overload. If the motor draws excessive current, the motor will shut off to reduce the likelihood of cable damage and the Electronic Torque Limiter LED will flash. Release the foot switch to allow the motor to restart. See the Operating Instructions section for information for removing the cable from a blockage.

If the Electronic Torque Limiter LED is on continuously, the motor has overheated. To reset the thermal overload, unplug machine, turn the REV/O-OFF/FOR switch to the O-OFF position and let the machine cool for at least 15 minutes. If the machine will not start or continuously trips during normal operation, take machine for service.
