Cable kinks or breaks. Operator forcing the cable. Do not force the cable. Let the cutter do the work.

Too much slack between machine and drain. Do not allow more than six inches between guide hose and drain.

Cable used in wrong size drain line.

A cable that is too large or too small in diameter for a line is more

likely to kink (See Table 1—Cable Application Chart).

Cable exposed to acid. Clean and oil cables regularly.

Cable tangles in drum/cage. Operator forcing the cable. Do not force the cable. Let the cutter do the work.

Machine run in reverse.

Do not run machine in reverse to retract cable from drain. Use re-

verse only if cable is caught in line.

Drum/cage stops while foot

pedal depressed.

Hole in pedal or hose. Replace as required.

Hole in diaphragm switch. If no hole found in pedal or hose, replace diaphragm switch.

Blown fuse. Replace with a 5 amp fuse (if 120 v motor) or 3 amp fuse (if 220 v

motor).

Motor turns in one direction

but not other.

Reverse switch failure. Replace reverse switch.

Ground fault circuit inter-

rupter trips and will not reset.

Damaged power cord or extension cord.

Replace cords.

Faulty ground fault circuit interrupter.

Replace ground fault circuit interrupter.

Failure to feed. Cable tangled in drum.

Make sure to use proper size cable for the job (see Table 1 – Cable

Application Chart).

Feed misadjusted.

If feed tension knob is too loose, the cable will slip. If it is too tight,

the feed rollers will wear prematurely.

Clean debris from around rollers. If rollers do not turn, cable will not

feed. Badly worn rollers must be replaced.

Worn cable. When cable coils wear flat, cable should be replaced.
