Machine Inspection
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 bro ken
cables, chemical burns, infections and other causes
®
and prevent drain cleaner damage.
Always wear safety glasses, RIDGID drain clean-
ing gloves, and other appropriate protective e quip -
ment when inspecting your drain cleaner. For extra
protection from chemicals and bacteria on the e-
quipment, wear latex, rubber or other liquid barrier
gloves under the RIDGID drain cleaning gloves.
1. Inspect the RIDGID drain cleaning 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 improper or damaged
gloves. The gloves protect your hands from the ro-
tating 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been replaced by a qualified repair person.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-
