Make sure FOR/OFF/REV switch is in OFF position
and machine is unplugged from power source.

Using Manual Feed Machine

1. Manually pull a sufficient length of cable out of the
drum to start the tool and cable into the sewer inlet.
2. Move FOR/OFF/REV switch into FOR (forward) po-
sition. Do not step on the air foot switch pedal at
this time.

3. Pull 18" - 24" from the machine - enough to form a
slight loop - and apply downward pressure with both
hands on the cable. Do not force the cable. Allow it
to feed itself into the drain. (See "Special Procedures"
for negotiating through traps.)
WARNING
Before starting machine, both operator's gloved
hands must be on the cable.
4. Exert sufficient downward pressure on cable to keep
it in sewer line while depressing air foot switch pedal
to start cable rotating.
5. Pull cable out of drum and allow cable to feed itself
into the line.
WARNING
Always keep hand on the cable to feel tension.
6. Continue to feed the cable into the line until resistance
or obstruction is encountered. The condition will gen-
erally become apparent to the operator as the cable
will have a tendency to twist sideways in the opera-
tor's hands.
7. Pull back sharply on the cable to free the cutter and re-
lieve the load on the cable. Slowly advance cable
back into the obstruction. Repeat this process until the
obstruction is clear. Remember, make sure the cutter
is rotating at all times and never force the cable.
WARNING
Do not allow tension to build up in the cable. This
will happen if the cutting tool hits a snag and stops
turning, but the motor and its drum continue to ro-
tate. Torque builds until the cable suddenly twists,
potentially wrapping around your hand or arm. This
can happen quickly and without warning, so pro-
ceed slowly and carefully as you feed the cable into
the drain. If tool gets hung up in an obstruction,
refer to Reverse Operating Instructions in the
"Special Procedures" section.
NOTE! Additional cable may be added if required. Refer
to "Special Procedures".
8. Several passes through thoroughly blocked drain
lines are recommended. After establishing drain flow,
increase cutter size to thoroughly clean the lines.
9. To retrieve cable from sewer line, pull cable into the
drum with machine in FOR (forward). The machine
should be kept running during the process for thorough
cleaning.
