and cable rotation and a pneumatic foot switch provides ON/OFF control of the motor. The K-40 is offered in both AUTOFEED and manual ver- sions. The AUTOFEED is integral to the four foot long front guide hose. The AUTOFEED allows the cable to be advanced and retrieved at a rate of 6 feet per minute. The front guide hose used with the AUTOFEED helps to protect fixtures and contain the liquid and debris thrown off the cable as it is retrieved from the drain. Manual feed ver- sions require that cable be fed in and out of the drain by hand. The two piece twist-lock drum will n ...

low these procedures for proper assembly. Mounting Guide Hose To K-40 1. If required, attach bracket to K-40 frame with 1/4" bolts provided (See Figure 3). Do not over tighten bolts. Figure 3 – Mounting Guide Hose to K-40 2. Pull approximately five feet of cable from the K-40. Insert the cable into the guide hose (the end with the plunger pin) and feed it through the guide hose until it reaches the AUTOFEED. Fully lift the levers of the AUTOFEED and feed the end of the cable through the end of the AUTOFEED. See Figure 4. 3. Attach the guide hose to the bracket on the K-40. ...

chine and correct any problems to reduce the risk of serious injury from electric shock, twisted or broken cables, chemical burns, infections and other causes and prevent drain cleaner damage. Always wear safety glasses, RIDGID drain clean- ing gloves, and other appropriate protective e quip - ment when inspecting your drain cleaner. For extra protection from chemicals and bacteria on the equip - ment, wear latex, rubber or other liquid barrier gloves under the RIDGID drain cleaning gloves.

cable coils indicates that the cable has been de - formed. This can be caused by kinking, stretching (mechanically pulling the cable) or running the cable in REVERSE (REV). Cables with space between the coils should be replaced. • Excessive corrosion – this can be caused by storing the cable wet or using the cable in corrosive chem- icals used in chemical clog removers. Corrosion weakens the cable and can make it brittle. Ex - cessively corroded cable should be replaced. All of these forms of wear and damage weaken the cable and make cable twisting, kinking or breaking more ...

application. The K-40 is made for • 3/4" to 11/2" lines up to 30' long with 1/4" cable • 3/4" to 11/2" lines up to 45' long with 5/16" cable • 11/4" to 2" lines up to 45' long with 5/16" IC (Inner Core) cable • 11/4" to 21/2" lines up to 30' long with 3/8" cable Drain cleaners for other applications can be found by consulting the Ridge Tool Catalog, on line at RIDGID.com or by calling Ridge Tool Tech nical Services at 800-519-3456. 4. Confirm that the equipment to be used has been properly inspected. 5. If needed, place protective covers in the work area. The drai ...

T-slot coupler allows the cutting tool to be snapped into the cable coupler. As the cutting tool is installed make sure that the spring-loaded plunger in the coupling on the end of the cable moves freely to retain the tool. If the pin sticks in the retracted position, the cutting tool may fall off in use. To remove cutting tool, insert the pin key into the hole in the coupling to depress the plunger and slide the coupling apart. (See Figure 8.) Figure 8 – Coupling and Uncoupling Tools 12. Position the foot switch for easy accessibility. You must be able to hold and c ...

WARD) position. Do not depress the foot switch yet. FOR/OFF/REV refers to the cable rotation and not to the direction of cable movement. Do not rotate the cable in reverse except as specifically described in these instructions. Running the drain cleaner in REV can damage the cable. Using Manual Feed Machine Grasp the cable with both gloved hands and pull a short section (6" - 12") of cable from 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 ...

rotating, the cable can twist, kink or break. Once the tool is free of the blockage and is turning again, you can slowly feed the rotating cutting tool back into the blockage. Do not try to force the tool through the blockage. Let the spinning tool “dwell” in the blockage to help com- pletely break it up. Work the tool in this manner until it has moved completely past the blockage (or blockages), and the drain is flowing. While working the blockage, the tool and cable may be- come clogged with debris and cuttings from the blockage. This can prevent further progress ...

opening. See Figure 11. The guide hose helps to protect the fixture from damage and contain the liquid thrown off the cable as it is retrieved from the drain. If the AUTOFEED is not kept within 6" of the drain opening, the cable will not be properly supported and may allow the cable to twist, kink or break. When using a machine with a front guide hose, pay at- tention to how the guide hose feels in your hand and watch the drum rotation. Because the guide hose is over the cable, there is less sensitivity to the loading of the cable, and it can be harder to tell if the tool ...

cable wind up or if the tool stops turning, immediately release the advance feed and depress the retrieve feed lever to free the tool from the blockage. Don’t keep the cable rotating if the tool is stuck in a blockage. If the tool stops turning and the drum keeps rotating, the cable can twist, kink or break. Once the tool is free of the blockage and the tool is turning again, you can slowly feed the rotating tool back into the blockage. Let the spinning tool “dwell” in the blockage to help completely break it up. Do not try to force the tool through the blockage. Wo ...
