5. Clean any debris from the cable and cutting tools.
Inspect cables for wear and damage. Inspect for:
• Obvious flats worn into the outside of the cable
(cable is made from round wire and profile should be
round).
• Multiple or excessively large kinks (slight kinks up to
15 degrees can be straightened).
• Space between the coils indicating the cable has
been deformed by stretching, kinking or running in
REVERSE (REV).
• Excessive corrosion from storing wet or exposure to
drain chemicals.
All of these forms of wear and damage weaken the
cable and make cable twisting, kinking or breaking
more likely during use. Replace worn and damaged
cable before using drain cleaner.
Make sure cable is fully retracted with no more than 6"
of cable outside of the machine. This will prevent
whipping of the cable at start up.
6. Inspect the tools for wear and damage. If necessary,
replace prior to using the drain cleaning machine. Dull
or damaged cutting tools can lead to binding, cable
breakage, and slow the drain cleaning process.
7. Make sure that the FOR/O-OFF/REV switch is set to
the O-OFF position.
8. With dry hands, plug cord into outlet. Test the GFCI in
the electrical cord to insure that it is operating cor-
rectly. When the test button is pushed in, the indicator
light should go off. Reactivate by pushing the reset
button in. If the indicator light goes on, the GFCI is
functioning properly. If GFCI is not functioning properly,
unplug the cord and do not use the drain cleaning
machine until the GFCI has been repaired.

9. Move the FOR/O-OFF/REV switch into the FOR po-
sition. Press the foot switch and note the direction of
rotation of the drum. If the foot switch does not control
the machine operation, do not use the machine until
the foot switch has been repaired. The drum should
rotate counter-clockwise when viewed from the front
of the drum, and will match the drum direction shown
on the warning label (Figure 5) and shown in Figure 6.
Release the foot switch and let the drum come to a
complete stop. Place the FOR/O-OFF/REV switch
into the REV position, and repeat above testing to con-
firm that the drain cleaner operates properly in reverse.
If the rotation is not correct, do not use the machine
until it has been repaired.
10. With the inspection complete, move the FOR/O-
OFF/REV switch into the O-OFF position and, with dry
hands, unplug the machine.
