the drum. ONLY run the motor in REV if the cutter has
become caught. If the cable begins to get stuck or
buckle/kink/ twist, immediately remove your foot from
the foot switch while rmly holding the cable with
both hands. Allow the machine to come to a complete
stop and the tension to release from the cable. Turn
the machine off and immediately manually rotate the
cable in the opposite direction until the twist or buckle
has been removed.
If drum continues to rotate under power when the
cable/cutter is stuck the cable can twist, buckle kink
or break.
Retrieving the cable
8. Move the motor switch to the OFF position. Do no
operate the motor in reverse.
9. Unplug the power cord.
10. Loosen the thumbscrew and hand feed all the cable
back into the drum, cleaning in cold water then oiling
the cable as you go. It is recommended that the cable
is continuously ushed through with clean water and
oiled as it is being retrieved from the pipe and again
before putting it away. This will prolong cable life and
prevent unpleasant odors as well as the damaging
effects of drain cleaning compounds.
11. Once all of the cable is fed back into the drum, tighten
the thumbscrew.

unpleasant odors as well as the damaging effects of
sediment and drain cleaning compounds. Cleaning and
lubricating should occur prior to storing the machine.
