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

K-750R Drain Cleaning Machine
Do not allow the cutter to stop turning while the ma-
chine is running. This can overstress the cable and
may cause twisting, kinking or breaking of the
cable. Twisting, kinking or breaking cable may
cause striking or crushing injuries.
Position machine cable outlet within 3' (0.9 m) of the
drain inlet or properly support exposed cable when
the distance exceeds 3' (0.9 m). Greater distances
can cause control problems leading to twisting,
kinking or breaking of the cable. Twisting, kinking or
breaking cable may cause striking or crushing in-
juries.
One person must control both the cable and switch.
If the cutter stops rotating, the operator must be
able to turn the tool OFF to prevent twisting, kinking
and breaking of the cable and reduce the risk of in-
jury.
Follow operating instructions to reduce the risk of
injury from twisted or broken cables, cable ends
whipping around, machine tipping, chemical burns,
infections and other causes.
1. Make sure that machine and work area is properly set
up and that the work area is free of bystanders and
other distractions.
2. Pull cable out of drum and feed into drain. At least one
foot (0.3 m) of cable must be in drain so that the
end of the cable will not come out of the drain and
whip around when the machine is started.
Directly route the cable from the outlet of the machine
to the drain opening, minimizing exposed cable and
changes in direction. Do not tightly bend the cable –
this can increase the risk of twisting or breaking.
3. Assume a proper operating position that will allow:
• Be sure you can control the ON/OFF action of the
foot switch and can quickly release the foot switch if
needed. Do not press foot switch yet.
• Be sure that you have good balance, do not have to
over reach, and cannot fall on the foot switch, drain
cleaning machine, the drain or other hazards.
• 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/O-OFF/REV
switch.
This operating position will help to maintain control of
the cable and machine. See Figure 11.

4. Move the FOR/O-OFF/REV switch to the FOR (FOR-
WARD) position. Do not depress the foot switch
yet. FOR/O-OFF/REV refers to the drum/cable rota-
tion 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

K-750R Drain Cleaning machines are not equipped with
AUTOFEED ® power feed units. If your machine has a
power feed unit, please see the operating instructions
for the RIDGID K-750 Drain cleaning machine for infor-
mation on proper power feed operation.

Feeding The Cable Into The Drain

Confirm that at least one foot (0.3 m) of cable is in the
drain. Grasp the exposed cable with both gloved hands
equally spaced and pull 6"-12" (150 mm - 300 mm) 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 (Figure 12).
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 con-
trolling 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 ro-
tating cable will work its way into the drain as you push on
