Special Operations - General Pipe Cleaners The Metro Manual

Operation
1. Before stepping on the foot pedal, pull cable from the drum and
slide it into the drain as far as it will go.
2. Tighten the knob at the top of the Power Cable Feed so that the
feed roller presses against the cable. Be sure not to over-tighten,
since this could cause excess cable wear.
3. The feed lever controls the feeding rate and direction of the ca-
ble. Move the lever down to feed cable out of drum. The further
the lever is moved downward, the faster the cable will feed out.
Move lever up to retract cable into drum. When the lever is in the
middle (neutral) position, cable will spin in place.

4. Move the motor switch to the FORWARD position.
5. With a leather-gloved hand on the Guide Tube or cable, depress
the air foot pedal to start machine. Feed the cable into the line
and against the obstruction with a firm, even pressure. Adjust the
feeding rate to the resistance met. Do not force the cable—let the
cutter do the work. The job won't go any faster and you could
damage the cable.
DO NOT USE TOO MUCH FORCE –
LET THE CUTTER DO THE WORK.
6. Don't leave too much slack in the cable since this will cause
whipping. If the cable starts to bend or build up too much twist,
release pressure on the foot pedal and rotate the drum in the
opposite direction to relieve the twist on the cable. Push any
excess cable back into the drum and then continue.
DO NOT ALLOW TOO MUCH SLACK IN THE CABLE
BETWEEN MACHINE AND DRAIN OPENING SINCE
THIS CAN CAUSE CABLE WHIPPING.
7. If you're having trouble getting around tight bends, try putting the
machine in reverse while applying steady pressure. (If using
Power Cable Feed, putting motor in reverse will cause the feed
control lever to operate opposite of normal.)
Note: If your machine is equipped with a momentary contact
reverse switch, you must hold the switch in position when operat-
ing the machine in reverse.
Don't do this for more than a few seconds at a time as this
could cause tangling in the drum or kinking.

8. If you still can't get around the bend, you're probably using too
large a cable. Switch to a smaller cable (See Cable Application
Chart—Table 1), or use the optional flexible leader.
9. When cable reaches the stoppage, put feed into neutral. Then,
allow the cable to progress forward slowly, chewing into the stop-
page as it goes. This slow, forward movement will reduce stress
on the cable while doing a more thorough cleaning job. A back
and forth action often works best.
Hint: It's often helpful to have a small stream of water running in the
line to wash the cuttings away while the machine is in operation and
after.
10. Be careful not to let the cutter get caught in the stoppage as you
work through it. This can cause kinking and breaking of the ca-
ble. When you feel the cable starting to twist in your hands, stop
the machine and pull back. This will free the cutter from the ob-
struction. Then allow the cable to move forward slowly into the
stoppage.
11. After the line has been cleared, return the cable to the drum with
the motor turning forward. This is important to prevent the cable
from tangling in the drum or in the line.
12. When the cutting tool is near the drain opening, take your foot off
the pedal to stop drum rotation. Never retract the cutting tool
from drain while cable is rotating. The cable could whip and
cause serious injury.
DO NOT USE REVERSE TO PULL THE CABLE OUT
OF THE DRAIN. RUNNING MACHINE IN REVERSE
CAN CAUSE THE CABLE TO TANGLE IN THE DRUM.

SPECIAL OPERATIONS

IF CABLE GETS CAUGHT IN LINE
The motor can be reversed to free the cable if it gets caught in line.
(Note: if using Power Cable Feed, putting motor in reverse will cause
the feed control lever to operate opposite of normal.)
1. Move motor switch to the reverse position.
2. Depress the foot pedal while retracting the cable.
3. After cable is loose, move switch back into forward position.
DO NOT RUN MOTOR IN REVERSE FOR MORE THAN
A FEW SECONDS AT A TIME. THIS COULD CAUSE
THE CABLE TO KINK OR TANGLE IN THE DRUM.
IF CABLE TANGLES IN DRUM
This is almost always caused by using too much pressure when feed-
ing the cable, or by feeding the cable while running the machine in
reverse. To untangle, rotate drum in opposite direction. This will usu-
ally get the cable to lie in the drum properly
If cable has become badly tangled, which will not happen when ma-
chine is used properly, it may be necessary to pull the entire cable out
of the drum and re-install it. (See "How to Install Cables In Drum"
section.)
