4. In order to help align the Spacers and Bearings, 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 components.
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.

TANGLED CABLE
If a cable loops over itself in the drum, it will not feed properly. Re-
move 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.
Solution
Do not force cable! Let the cutter do the work.
Allow a distance of no more than two feet between machine and drain.
A cable that is too large or too small in diameter for a line is more likely
to kink. (Consult Cable Application Chart – Table 1.)
Clean and oil cables routinely.
Replace damaged component.
If no problem found with the pedal or hose, replace the diaphragm
switch.
Allow motor to cool. Press reset button.
Replace switch. Note: Momentary contact switch must be held in
position to use reverse.
Replace cords.
Remove excess moisture from area.
Take motor to authorized service center. (Call General for details.)
Replace Ground Fault Interrupter.
Do not run machine in reverse. Use proper cable size. (Consult Cable
Application Chart – Table 1.)
Clean and lubricate feed rollers regularly. Replace worn rollers.
When cable coils wear flat, cable should be replaced.
Do not force cable. Do not allow too much slack between the cable
and the machine.
Replace slip clutch.
