4. Firmly tighten bolts holding loading wheel to handles.
5. Adjust gap between guard and drum to less than
1 /
that gap between belt guard and drum is less than
to prevent fingers and other objects from being pulled
into the belt and pulley. Adjust if necessary.
Installing Cable
Do not remove the bands or cables from the cable car-
ton. The cable is under tension and can whip or strike if
released.
Manual Cable Installation – this can be used for both
Manual and AUTOFEED units.
1. Retrieve male coupling end of cable through the
center hole of the carton and pull approximately 6' of
cable from the carton.
2. Connect the male coupling of the cable to the pigtail
coupling (See Figure 4). Confirm connection is se-
cure.
3. Pull short sections of cable from the carton and man-
ually feed into the drum. Do not turn machine ON.
AUTOFEED Cable Installation
Handles
1. Retrieve male coupling end of cable through center
hole of carton and pull cable from carton. Lay cable
out straight in a flat area (such as an empty paved
parking lot or driveway) with no obstructions or items
that could become wrapped around the cable.
2. When using an AUTOFEED to load cable, the rotat-
ing cable will tend to walk sideways. To prevent this,
place suitable stops (such as wood blocks) on either
side of the cable at 10 foot intervals.
3. After properly inspecting and setting up the drain
cleaner, attach the cable to the pigtail as shown in
Figure 4. Make sure that no one is in the area around
the cable. Tighten the AUTOFEED knob so that the
roller touches the cable plus one additional turn. With
the FOR/OFF/REV switch in the FOR position, press
the foot switch to start the drum turning. Move the
feed handle in the opposite direction of the cable ro-
tation to feed the cable into the drum.
Belt Guard
Fasteners 4. When 10' of cable is left outside of the drum, step off
the foot switch and move the FOR/OFF/REV switch to
OFF. Loosen the AUTOFEED knob and manually
feed the remaining cable into the drum. Do not use the
AUTOFEED to put all of the cable in the drum. The
cable end can whip around and cause serious injury.
