The RIDGID K-400 AF w/C-45 IW (27013) Auto-Feed Drum Machine for 1 1/2 in. to 4 in. Drain Lines, with C-45 IW 1/2 in. x 75 ft. Integral Wound Cable (115V) offers reliable power that cleans tough everyday drain line blockages in tubs, showers and sinks. A sleek profile and user-friendly design get you up and running easily -- and on to the next job quickly. The K-400 is ideal for drain cleaners, service plumbers, facility and institutional maintenance departments and property management companies. Please note that the K-400 is not designed to remove root blockages.

The K-400 will clean drain lines from 1 1/2" to 4" (40 to 100mm) in diameter and 100 feet (30.5m) in length depending on size of the cable. The corrosion-resistant cable drum holds 75 feet (22.5m) of 1/2" (12mm) diameter cable or 100 feet (30.5m) of 3/8" (10mm) diameter cable. The cable spins at 165 RPM.

The K-400 drum is belt-driven by a 380-watt electric motor that has a grounded electrical system. An integral Ground Fault Circuit Interrupter (GFCI) is built into the line cord. A FOR/OFF/REV (or 1/OFF/2) switch controls drum and cable rotation, while a pneumatic foot switch provides ON/OFF control of the motor.

The K-400 features a cable control system that consists of a torque limiter to stop the drum from rotating when the tool stops rotating and the torque exceeds the set value. This helps to prevent cable damage from cable flip over in the drum. The torque limiter is designed to work with 3/8" and 1/2" integral wound (IW) cable, and may not protect other cables.

The included "Solid-Core" Integral Wound cable is durable and kink-resistant. The cable has a quick change coupling system for connecting or disconnecting tools. The included "AUTOFEED" automatic cable feed powers cable in and out of the drain at a rate of 10-14 feet per minute. Reversing the direction of the AUTOFEED will feed the cable back into the drum.
