TROUBLE SHOOTING GUIDE (Table 3)
Problem
Probable Cause
Solution
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.
Allow no more than two feet between machine 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. (Consult Table 1—Cable Applications.)
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 running in reverse.
Do not run the machine in reverse to retract the cable from the drain.
Distributor tube frozen.
Lubricate distributor tube bushings.
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.
Drum/cage turns in one direc-
tion but not other.
Reverse switch or momentary con-
tact switch failure.
Replace switch. Note: Momentary contact switch must be held in
place when using reverse.
Ground fault circuit interrupter
trips and will not reset.
Damaged power cord or extension
cord.
Replace cords.
Short circuit in motor.
Take motor to authorized repair center.
Faulty ground fault circuit interrupter. Replace ground fault circuit interrupter.
Motor turns but drum/cage
does not.
Safety Slip Clutch (optional)
engaged.
Do not force cable.
Failure to feed.
Cable tangled in drum.
Do not run machine in reverse. Use proper cable size. (Consult Cable
Application Chart—Table 1).
Feed misadjusted.
If feed pressure knob is too loose the cable will slip. If it is too tight the
feed rollers will wear prematurely.
Feed roller frozen.
Clean and lubricate feed rollers regularly. Replace worn rollers.
Worn cable.
When cable coils wear flat, cable should be replaced.
TANGLED CABLE
If a cable loops over itself in the drum/cage, it will not feed properly.
Remove and reload the cable to restore function. If the cable kinks, it
is evidence of abuse and results from the use of too much pressure or
use of the wrong size cable for the line. Do not force the cable — let
the cutter do the work.
5. The Feed Roller Axle should then be inserted through the same un
-threaded Axle hole and should continue to be guided through the
Spacers and Bearings to the threaded Axle hole on the other side
of the Carrier.
6. Securely tighten the Axle to the Carrier with a 3/16” allen wrench.
