ure to feed can usually be traced to the follow-
ing possibilities:
DIRT ACCUMULATION
Over time, dirt can harden enough to stop roller
rotation. Flushing with water followed by lib-
eral oiling can usually restore function. If disas-
sembly is required, proceed as follows:
1. Remove the feed tension knob, springs and
spring plunger. Note the positioning of these
parts to ease re-assembly. The top roller can
now be removed.
2. Remove the end caps and thrust washers from
the bottom housing cylinders. The bottom roll-
ers can now be removed.
3. Re-assembly is done in reverse order.
DAMAGED ROLLER
Excessive use may wear a roller to the point of
failure. It is recommended that all three rollers
be replaced at the same time. The replacement
roller is an assembly consisting of one Feed Roll-
er, two Feed Roller Bearings, and two Bearing
Spacers.
NOTE: The Bearing Spacers must be installed be-
tween the Carrier and each Feed Roller Bearing
(as illustrated below) in order to ensure proper
operation and to obtain maximum Feed Roller
life.

To Replace the Feed Roller Assembly:
1. Remove the Feed Roller Assembly by unscrew-
ing and removing the Feed Roller Axle.
2. For convenience, the components are assem-
bled and wired together at the factory. Before
attempting to install the assembly, hold the as-
sembly together and remove the wire.
3. While still holding the Feed Roller Assembly
together, insert it into the slot opening of the
Carrier.

4. In order to help align the Spacers and Bear-
ings, insert a pencil point or similar object
through the un threaded end of the Axle hole
in the Carrier. After removing the pencil point,
continue to maintain the alignment of the com-
ponents.
5. The Feed Roller Axle should then be inserted
through the same unthreaded Axle hole and
should continue to be guided through the Spac-
ers 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" hex wrench.
TANGLED CABLE
If a cable loops over itself in the drum, 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.
TROUBLESHOOTING
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. Al-
low 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.
Cable exposed to acid. Clean and oil cables
regularly.
CABLE TANGLES IN DRUM
Operator forcing the cable. Do not force the
cable. Let the cutter do the work.
Machine running in reverse. Do not run the ma-
chine in reverse to retract the cable from the
drain.
DRUM 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 TURNS IN ONE DIRECTION BUT NOT
OTHER
Reverse switch failure or momentary contact
switch. Replace switch. Note: Momentary con-
tact switch must be held in position to use re-
verse.
