Frequently Asked Questions - FlexShaft K912 RIDGID

What types of drills can I use with the FlexShaft K9-12 drain cleaner?
Use only a cordless drill with a speed of 1,800 to 2,500 RPM, a chuck of at least 3/8 in (10 mm), and an adjustable clutch. Never use a corded drill, hammer drill, or impact driver. The drill must have a momentary contact trigger (non-locking).
How do I install the cleaning chain on the cable?
Loosen the set screws with the provided 3 mm Allen key, place the cleaning chain, chain sleeve, and spacer sheath onto the cable. Ensure the bare cable does not exceed 1/4 in (6 mm). Tighten the screws 45°-90° after contact with the cable. Follow the collar spacing according to the table (e.g., 1 3/4 in for 1 1/2 in pipe).
How do I use the drain cleaner to clear a drain?
Position the drain cleaner within 1 m of the access, insert at least 1 ft (0.3 m) of cable into the pipe, then start the drill following the rotation direction (arrow). Advance the cable slowly until the blockage, then let the chain run at full speed while gradually pulling back the cable. Never force it. Maintain a trickle of water if possible.
What safety risks should I be aware of?
Always wear safety glasses and gloves. Risks of entanglement, cable kinking or breakage, electric shock (if using a corded drill), chemical burns or infection (from drain contents). Do not let the chain spin in the open air. Keep one hand on the cable at all times. Do not use near flammable gases or liquids.
How do I maintain the FlexShaft drain cleaner?
Clean the sheathed cable with a towel while retracting. Wash the drum with warm soapy water or a mild disinfectant. Lubrication is lifetime, but you can apply RIDGID FlexShaft lubricant on the sheath to ease feeding. Replace the sheathed cable if worn (procedure in the manual).
What if the cable kinks or bends?
This may be due to excessive force, improper cable support, an incorrectly adjusted chain, or an unsuitable drill. Immediately stop the drill, remove the cable, and inspect. Follow usage instructions: do not force, keep one hand on the cable, and ensure the drill is properly set (clutch).
Can I use the drain cleaner with an inspection camera?
Yes, the FlexShaft is suitable for cleaning associated with camera inspections. Position the camera at least 1.5 ft (0.5 m) behind the cleaning chain. Never let the chain hit the camera head or cable to avoid damage.
How do I adjust the drill's clutch for the drain cleaner?
Set the drill's torque collar to about 25% of its maximum (e.g., position 5 on a 1-20 scale). Use the screwdriving mode (◀). If the drill's clutch engages before the drain cleaner's integrated clutch, gradually increase the torque setting until the drill operates normally.
What accessories are available for the K9-12?
Single or double cleaning chains (with or without carbide teeth) for 1.25 to 2 in pipes, nylon brushes (1.5 and 2 in), penetrating heads (1.5 and 2 in), FlexShaft lubricant in cartridges, replacement sheathed cable of 50 ft, and sleeves for thin-wall pipe. References in the RIDGID catalog.
How do I transport and store the drain cleaner?
Rewind the cable and chain into the drum, secure the cap, remove the drill from the drive shaft. Store in a dry place, protected from weather, out of reach of children. Do not leave the drill mounted during transport or storage.

RIDGID FlexShaft K912 - Machine and Work Area Set-up - 1

RIDGID FlexShaft K912 - Machine and Work Area Set-up - 2

RIDGID FlexShaft K912 - Machine and Work Area Set-up - 3

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 lo-

cation. Do not use the Drain Cleaning Machine while standing in water.

  1. 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.

Best drain cleaning results will occur if water is flowing during the drain cleaning process to wash away debris. For 1/4" and 1½" sink drains, cut away wall pipes are available to allow this. See Figure 3 for installation. Place a container to catch any drain contents that may spill.

Figure 5 – Example of Extending Drain Access to within 3' of Machine Cable Outlet

  1. Position the Drain Cleaning Machine so that the cable outlet is within 3' (1 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 3' (1 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.

  1. Rotate the cable cap to move the arrow to unlock position and remove the cap (Figure 6). Retrieve chain knocker and cable assembly from the drum. Feed the chain knocker through the cable cap hole and lock the cable cap in original position. (Figure 7).

  1. Pull approximately 4' (1.2 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 4' (1.2 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 machine for easy accessibility. You must be able to hold and control the cable assembly and the drill switch.
  7. With dry hands, insert the battery into the drill.

Battery Powered Drill Set-Up and Operation

See the Specifications section along with this section for information on acceptable battery powered drills for use with the FlexShaft Drain Cleaning Machines. There are many types of battery powered drills available, and not all are appropriate for use with the FlexShaft Drain Cleaning Machines. If there is any question about appropriateness of a drill for this application, do not use it. Remove the battery from the drill before making any adjustments or attaching to/removing from the drain cleaning machine.

Drill Switch

The drill must be equipped with a momentary contact switch without a switch lock. This means that the drill will only turn when the operator is depressing the drill switch. If the drill switch is released, the drill will turn OFF. Set drill rotation to match the arrow on the machine (see Figure 4).

Drill Speed

When using your FlexShaft Drain Cleaning Machine, the required rotational speed range is 1800 – 2500 rpm. Cleaning will be optimized by rotating the chain knockers closer to the 2500 rpm maximum. To do this, know your battery powered drill specifications and settings to optimize operation. Many battery powered drills have multiple speed settings, and typically the highest speed is in the range for operation of the FlexShaft equipment. Do not operate the FlexShaft drain cleaning machine at over 2500 rpm.

Figure 8 – Example Drill Settings

Drill Adjustable Clutch Setting

Always use a battery powered drill equipped with a properly set adjustable clutch. The drill should be used only in the "screw driving mode" (◀) for the drill adjustable clutch to work. When the drill adjustable clutch releases, the motor continues to turn but the drill chuck

does not. Many times this is accompanied by vibration/noise from the drill. When using the K9-12 FlexShaft Drain Cleaning Machine, always start with the drill adjustable clutch set to approximately 25% of the total clutch adjustment range (example – if the torque adjustment collar on the drill is marked from 1 to 20, the initial setting should be 5).

Battery powered drills are often also equipped with "Drill" (☐) and "Hammer" (☐) modes of operation (Figure 8). In these modes, the adjustable clutch does not work, and these modes should never be used for FlexShaft Drain Cleaning Machine operation.

Operate the drain cleaner per these instructions with the chain knocker in a drain. The K9-12 FlexShaft machine integral clutch should release first before the drill clutch releases. If during operation the drill clutch continuously releases ("clutches out"), before the integral K9-12 FlexShaft Drain Cleaning Machine clutch, then the drill clutch must be adjusted. Release the drill switch and remove the drill from machine. The drill adjustable clutch setting should be increased. The drill clutch can be increased in steps until the drill runs smoothly and no longer releases before the K9-12 FlexShaft machine integral clutch.

If the integral FlexShaft machine clutch continuously releases, withdraw the cable from the drain. Review the drain cleaner set up and operation and confirm everything is correct – an important part of the set up for proper operation is chain knocker selection and adjustment (See Figures 10 & 11). Make any needed changes and continue cleaning drain. If the integral K9-12 Machine Clutch continues to disengage during use, consider using another RIDGID drain cleaning 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. 14 " chain knockers are used on 14 " cable, etc. Do not use a larger size chain knocker on a smaller cable (for instance 516 " on 14 ]). See Figure 9 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 scale and 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. See Figure 10, Attachment Selection Charts.

Figure 10B – Attachment Selection Charts

  1. Figure 11 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.

Exped 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"). Exposed cable varies with the amount of cable out of the drum. The more cable out of the drum, the smaller the exposed cable. Exposed cable may need to be set with cable out of the drum for best results,

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. 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.

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

Figure 11 – Chain Knocker Installation/Adjustment

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 11. 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 11, use the supplied hex wrench to securely tighten the collar set screws. Place set screw tip against cable, then tighten an additional 18 to 14 turn (45° to 90° degrees). 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 (See Figure 10B).

Brushes can be assembled in a variety of configurations, with some options shown in Figure 12.

natural_image Close-up of a metallic cable with twisted wires and a metallic connector (no visible text or symbols)

Figure 12B – Two Spaced Brushes

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 13 for installation information.

RIDGID FlexShaft K912 - WARNING - 5

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 use with a corded drill. Operating with a corded drill increases the risk of electrical shock.

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

Practice good hygiene. Do not eat or smoke while handling or operating the tool. After han-

dling 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.

Keep 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 3' (1 m) of the drain inlet or properly support exposed cable assembly when the distance exceeds 3' (1 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 cordless drill. Do not lock drill switch in the ON position during operation. If the cable stops rotating, the operator must be able to release the drill switch 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 drill (see Figure 14):

  2. Be sure you can quickly release the drill switch.

  3. Your gloved hand 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..

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

text_image 3' (1 m) MAX.

Figure 14 – In Operating Position

  1. Confirm that at least 1' (0.3 m) of cable assembly is in the drain.
  2. Confirm that the drill directional switch is in the forward direction, and depress and release the drill switch, noting the direction of the drill chuck. Drill rotation should match the arrow on the drum (See Figure 4). Do not rotate the cable in reverse except as specifically described in these instructions. Running in reverse can damage the FlexShaft cable.
  3. Place one hand on the cable assembly and other hand on the drill grip.
  4. 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 when withdrawing the cable. It's important to let the speed of the chain knocker clean the drain – do not force chain knockers into blockages.

8. 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 15). Add lubricant to the towel as needed during the process.

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.

9. Rotating the Chain Knocker

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

The general operating steps for the FlexShaft Drain Cleaning Machines (see below):

RIDGID FlexShaft K912 - Rotating the Chain Knocker - 1

text_image Diagram illustrating three stages of chain-linking or recombination process with arrows indicating direction
  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 knocker 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.

RIDGID FlexShaft K912 - Rotating the Chain Knocker - 2

text_image Diagram illustrating chain-linking process with numbered steps and directional arrows indicating movement
  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 16 – General Operating Steps with Chain Knocker

Only rotate the cable/chain knocker when the chain knocker is at least 1' in the drain. To rotate the cable, firmly grip the drill handle and depress the drill switch. The person controlling the cable assembly must also control the drill switch. Do not operate the machine with one person controlling the cable assembly and another person controlling the drill. 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 drill trigger to stop cable rotation. When clearing blockages, operate the cable at full speed for best cleaning. Do not force the chain knocker into blockages. In some cases, using variable speed will assist with navigating turns. Rotating the chain knocker in FORWARD or REVERSE for a short time while advancing the cable assembly can help it negotiate the drain and blockages.

  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 16, 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 16, Step 2).

  2. 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 16, Step 3).

  3. With the chain knocker past the blockage/area to be cleaned, fully depress the drill 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 16, Steps 4 & 5). If the cable stops turning, do not continue operating the drill. This may cause the cable to twist and kink. At any time, release the drill switch to stop cable rotation.

Monitor the feedback from the feel of the cable assembly in your hand and the sound of the drill/knocker in the drain. If the integral FlexShaft machine clutch or the drill clutch disengages (indicated by noise from the integral clutch or drill and possibly some vibration of the drill), the cable has likely stopped turning. See Drill Adjustable Clutch Setting in the Battery Powered Drill Set-up and Operation section. When this happens, release the drill switch to stop the rotation of the drill. Once drill rotation is stopped the clutch will automatically reengage, however, if the cable end is stuck, it must be moved out of the blockage before proceeding.

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, it may be able to be freed by running the drill in reverse for a short time. Do not run in reverse for more than a few seconds to prevent cable damage. 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. Remove the blockage from the knocker and cable and continue cleaning the drain as detailed above.

If using with a camero do not run the chain knocker into the camera head or push rod.

In some cases, to clean the opposite side of the pipe it may help to run the drill in REVERSE for a short time.

  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 16, Step 6).

  2. Watch for your sheath marking as the cable assembly is retrieved; listen carefully to the sound of the knocker as it approaches the pipe entrance. Release the drill 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 can cause damage or serious injury.

  1. If needed for complete cleaning, repeat the above procedure.

  2. 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 17 for general steps.

Step 3
Figure 17 – Cleaning Drain Walls With Brush

  1. Advance the brush (generally not rotating) into the drain.
  2. When close to the area of the drain to be cleaned, 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.

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 judgement of the user.

Penetrating tip heads can also be used with brushes or chain knockers for additional accessory customization.

Draining the Drum

If the cable is wiped clean as it is pulled from the drain, there should be minimal need to drain the drum. If needed, remove the cable cap and turn the machine over to drain.

Transportation and Storage

WARNING Feed all of cable assembly and chain knocker into the drum and secure the cap. Remove the drill from the input shaft. Do not leave the drill attached during transport and storage to prevent tipping and damage to the drain cleaner.

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

Drill should be removed from drain cleaner before any maintenance is performed.

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

Cleaning

It is good practice to wipe dirt and debris from the cable assembly as it is pulled from the drain to help keep the equipment clean. 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. Drain the machine as needed.

Lubrication

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

Cable Assembly Replacement

  1. Place the Drain Cleaning Machine in Horizontal use position.
  2. Pull entire cable assembly from housing.
  3. Using a Philips-head screwdriver, remove the fasteners holding the housing together. Remove the top housing (Figure 18)
