Operation; Feeding The Cable Into The Drain - RIDGID K-750 Manual

K-750 Drain Cleaning Machine
• You must be able to place at least one hand on the
cable at all times to control and support the cable.
• You must be able to reach the FOR/OFF/REV
switch.
This operating position will help to maintain control of
the cable and machine. See Figure 12.
4. Move the FOR/OFF/REV switch to the FOR (FOR-
WARD) position. Do not depress the foot switch yet.
FOR/OFF/REV refers to the drum/cable rotation and
not to the direction of cable movement. Do not rotate
the cable in reverse except as specifically described
in these instructions. Running the drain cleaner in
REV can damage the cable.

Operation

The K-750 Drain Cleaning Machine is available in two
different feed configurations, either manual feed or AUTO -
FEED. A K-750 supplied with the AUTOFEED can either
feed the cable with the AUTOFEED (feed lever position) or
by manually pulling the cable from the drum and feeding it
into the drain. With the AUTOFEED you can switch back
and forth between operating methods as needed. A K-750
without the AUTOFEED can only be used manually.

Feeding The Cable Into The Drain

Manual Operation
Confirm that at least one foot (.3 m) of cable is in the drain.
Grasp the exposed cable with both gloved hands equally
spaced and pull 6"-12" of cable out of the drum so that
there is a slight bow in the cable. Gloved hands must be
on the cable to control and support the cable. Improper
cable support can allow the cable to kink or twist and can
damage the cable or injure the operator. Make sure that
the cable outlet of the drain cleaner is within 3' of the drain
opening.
Depress the foot switch to start the machine. The person
controlling the cable must also control the foot switch. Do
not operate the drain cleaner with one person controlling
the cable and another person controlling the foot switch.
This can lead to twisting, kinking and breaking of the
cable. Feed the rotating cable into the drain. The rotating
cable will work its way into the drain as you push on the
cable with gloved hands. Do not allow the cable to build up
outside the drain, bow or curve. This can allow the cable
to twist, kink or break.
When the cable has been fed into the drain opening,
pull 6"-12" more cable from the drum and continue feed-
ing the rotating cable into the drain.
AUTOFEED Operation
Confirm that at least one foot (.3 m) of cable is in the drain.
Tighten the AUTOFEED knob (Figure13) so that the roller
12
touches the cable plus one additional turn. Do no over-
tighten the knob – this can cause premature failure of the
AUTO FEED or cable.
Grasp near the center of the exposed length of cable
with a gloved hand. Gloved hand must be on the cable to
control and support the cable. Improper cable support can
allow the cable to kink or twist and can damage the cable
or injure the operator. Make sure that the cable outlet of
the drain cleaner is within 3' of the drain opening. Place the
other hand on the AUTOFEED lever. AUTOFEED lever
should be in neutral (Vertical) position (see Figure 13).
See "Using Machine With A Front Guide Hose" if using a
guide hose.

NOTE: Rate of cable advance or retrieve varies by
handle movement from neutral.
Depress the foot switch to start the machine. The person
controlling the cable must also control the foot switch. Do
not operate the drain cleaner with one person controlling
the cable and another person controlling the foot switch.
This can lead to twisting, kinking and breaking of the
cable. With the cable rotating, move the AUTOFEED
control handle in the same direction that the cable rotates.
This will cause the cable to feed out of the machine. The
further the control handle from the neutral position, the
faster the cable will be fed (up to 20' per minute, maxi-
mum). The rotating cable will work into the drain as you
control the cable with your gloved hand. Do not allow
the cable to build up outside the drain, bow or curve.
This can allow the cable to twist, kink or break.
