K-750 Drain Cleaning Machine

Pre-Operation Inspection

WARNING
Before each use, inspect your drain cleaning ma-
chine and correct any problems to reduce the risk of
serious injury from electric shock, twisted or broken
cables, chemical burns, infections and other causes
and prevent drain cleaner damage.
Always wear safety glasses, RIDGID drain cleaning
gloves, and other appropriate protective equipment
when inspecting your drain cleaner. For extra pro-
tection from chemicals and bacteria on the equip-
ment, wear latex, rubber or other liquid barrier
gloves under the RIDGID drain cleaning gloves.
1. Inspect the RIDGID drain cleaning gloves or mitts
("gloves"). Make sure they are in good condition with
no holes, tears or loose sections that could be caught
in the rotating cable. It is important not to wear im-
proper or damaged gloves. The gloves protect your
hands from the rotating cable. If the gloves are not
RIDGID drain cleaning gloves or are damaged or
worn out, do not use machine until RIDGID drain
cleaning gloves are available. See Figure 6.

2. Make sure that the drain cleaning machine is un-
plugged and inspect the power cord, Ground Fault
Circuit Interrupter (GFCI) and plug for damage. If the
plug has been modified, is missing the grounding
prong or if the cord is damaged, to avoid electrical
shock, do not use the machine until the cord has
been replaced by a qualified repair person.
3. Clean any oil, grease or dirt from all equipment han-
dles and controls. This helps prevent the machine or
control from slipping from your grip.
4. Make sure the foot switch is attached to the drain
cleaning machine. Do not operate the machine with-
out the foot switch.

5. Inspect the drain cleaning machine for the following
items:
• Proper assembly and completeness
• Any broken, worn, missing, mis-aligned or binding
parts
• Smooth and free movement of the AUTOFEED
handle throughout range. Rotate the drum and
make sure that it turns freely without binding.
• Presence and readability of the warning label (see
Figure 7).
• Presence and proper adjustment of the belt guard.
Belt guard should be adjusted so that the gap be-
tween the guard and the drum is no more than
(See Figure 3.)
• Any condition which may prevent safe and normal
operation.
If any problems are found, do not use the drain cleaner
until the problems have been repaired.

6. 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 the profile
should be round).
• Multiple or excessively large kinks (slight kinks up to
15 degrees can be straightened).
• Space between cable coils indicating that 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.
