K-75A/B, K-1500A/B, & K-1500SP Drain Cleaning Machines 8. If cable loads down in the obstruction, relieve load by pulling back on cable with short, quick jerks to free cutter. Slowly advance cable back into the obstruction. Repeat this process until the obstruction is clear. Remember, make sure the cutter is rotating at all times and never force the cable. At this point, progress depends upon the sharpness of the tool and nature of the obstruction. WARNING Do not allow tension to build up in the cable. This will happen if the cutting tool hits a snag and stops turning, but the motor and cable continue to rotate. Torque builds until the cable suddenly twists, potentially wrapping around your hand or arm. This can happen quickly and without warning, so proceed slowly and carefully as you feed the cable into the drain. Releasing clutch handle will stop the cable rotating and releases the torque. If tool gets hung up in an obstruction, refer to Reverse Operating Instructions in the "Special Procedures" section. 9. Once obstruction is cleared, it is recommended that operator flush debris from line with running water. Repeat Step 8 several times if necessary for thorough cleaning job and then work cable through additional stoppages as required. 10. To add cable, the following procedure should be followed: • After reaching the end of each cable section, turn the machine OFF. • Secure the cable by looping it in the line (Figure 7). This procedure is especially useful when cleaning a line with a steep grade. Figure 7 - Looping Cable In Line • With line secured, insert another section of cable in through the front of the machine (female end first) until approximately one foot remains out the front of the machine. • Attach cable to cable in line and resume operation. 11. To retrieve cable from drain line, the following proce- dure should be followed: • Leave FOR/OFF/REV switch in FOR (forward) position. • Push down on clutch handle to engage cable. With mitted hand pull cable out of line (if possible) or hold cable against edge of inlet to thread the cable out until loop forms in front of the machine. NOTE! By holding the cable against the edge of the inlet, the rotation will rapidly "thread" the cable out of the line. • When loop forms, release clutch handle and push excess cable back through machine. Disconnect one section at a time. WARNING When disconnecting sections, remember to turn unit off and secure cable in line. • Once section of cable is removed, insert the secured cable in through the front of the machine and continue removing sections until tool on last section of cable is just inside sewer inlet. HINT! When placing removed cables back into cable carrier, reconnect all cables. This assures easy removal at next job. WARNING Never retract tool from sewer inlet while cable is rotating. Tool can whip causing serious injury. 12. Turn FOR/OFF/REV Switch to OFF position. 13. Pull remaining cable and tool from sewer. 14. Unplug power cord and remove guide hose. CAUTION After using, thoroughly flush and drain cables, couplings and tools with water due to damaging effects of some drain cleaning compounds. Special Procedures Reverse Operation Running machine in reverse will cause premature failure of cable. Use reverse only to free a tool or cable caught in an obstruction. If this should occur, immediately release clutch handle and place FOR/OFF/REV switch to OFF position. After motor comes to a complete stop, place FOR/OFF/REV switch in the REV (reverse) direction. Engage clutch handle only until cable or tool is free of obstruction. Once it is free, release clutch handle immediately. Turn unit OFF. Run unit in FOR (forward) direction and follow normal operating procedure. WARNING Never operate this machine in REV (reverse) for any other purpose. Operating in reverse can damage a cable and cause serious injury. Cable Applications Standard Cable Standard 7/8″ or 11/4″ cable can be used in straight lines from 3″ through 6″ and through fittings.
