TIP: Know approximately where you are going. Over -
running cable into city sewers or septic tanks can
cause cable damage and retrieval problems.
NOTE! Additional cable may be added if required. Refer
to Special Applications Procedure section.
Do not put the machine in reverse. The ma-

chine should be kept running during the retrieval process
for thorough cleaning.
NOTE! A continuous flush of water should be used to
clean the cable and tool as they are retrieved.

Special Procedures

Main Sewer Or Septic Tank Overrun

It is very important to know the approximate distance from
inlet to main sewer or septic tank. Over-running cable too
far into main sewer or septic tank can allow cables to
knot-up and prevent their return through small lines.

Reverse Operation

Running machine in reverse will cause premature failure
of cable. Use reverse only to free a tool caught in an ob-
struction. If this should occur, immediately remove foot
from air foot switch pedal and allow machine to come to a
full and complete stop. Place FOR/OFF/REV switch to
REV (reverse) position. If machine has automatic feed,
loosen feed knob. Grasp cable with gloved hands and pull
while jogging air foot switch pedal. When tool is dislodged
and drum has stopped rotating, place FOR/OFF/REV
switch in FOR (forward) position and follow normal oper-
ating procedure.
Never operate this machine in REV (re-

verse) for any other purpose. Operating in reverse can
damage a cable and cause serious injury.

Loading The Machine On Vehicle

The stair climber can be raised from the lower position
(used to move the machine up and down stairs) to the
upper position (used to load the machine onto truck beds).
To place the stair climber in the upper position, raise the
stir climber by pulling out the locking pin and lifting the
cross member until the pin locks in the upper position. Tip
the machine backwards and rest the stair climbers on
the truck bed. Lift up on the front of the machine and
slide it onto the truck (Figure 12) .
Use proper lifting technique – lift with
WARNING
your legs, not your back!!
NOTE! Take care not to damage electrical cord or air
foot switch hose.
