and forth to clear the obstruction. At this point,
progress depends on the type of tool being used
and nature of the blockage. Advance cable slowly.
7. If cable gets hung up in the obstruction, release the
clutch handle to stop the rotation of the cable. Refer
to “Reverse Operation” in the “Special Procedures”
section.
8. Once obstruction is cleared, it is recommended that
operator flush debris from line with running water.
Repeat
Step 6
several times if necessary for thorough
cleaning job and then work cable through additional
stoppages as required.
Cable is not attached inside drum. When
approaching end of cable, keep hand securely on cable
to avoid losing it down the drain.
9. To withdraw cable from line with machine running,
leave FOR/OFF/REV lever in FORWARD position
and slowly pull cable from drain.
10. As excess cable is retrieved from line, hand-feed
cable back into K-50.
11. Release clutch handle just prior to cable or tool
emerging from drain opening. Cable or tool may con-
tain debris and splash work area.
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.
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 po-
sition. 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 ob-
struction. Once it is free, release clutch handle immedi-
ately. Turn unit OFF. Run unit in FOR (forward) direction
and follow normal operating procedure.
Never operate this machine in REV (re-
verse) for any other purpose. Operating in reverse can
damage a cable and cause serious injury.
Brake Adjustment
The cable adapter is equipped with a quick-acting brake
which will immediately stop rotation of the drum when the
clutch handle is pulled upwards.
After attaching cable adapter to your K-50 Machine, test
for proper braking action as follows:
1. Put switch in FORWARD position to start motor.
2. Push clutch handle forward to engage clutch driver
jaws. Drum will rotate.
3. Pull up on clutch handle to release jaws and activate
brake. Drum should stop turning immediately.
If drum does not stop immediately, readjust brake mech-
anism as follows:
WARNING
Make sure machine is unplugged from power source
before making any adjustment.

6. Operate machine to check for proper braking action.
7. If drum does not stop immediately, repeat
Steps 2
and 3
until brake functions properly.
8. Tighten set screws “A” and recheck tension on set
screw “B”.
Due to normal wear, future adjustment will become nec-
essary for effective braking.
