SAFETY SLIP CLUTCH
The safety slip clutch is located between the motor and the Cable
Drive Coupler. It is designed to protect your cables from breakage and
is factory preset to slip at 18-20 ft-lbs. of torque. Under normal usage
of your machine, no adjustments need to be made to the clutch. If you
find it necessary to change the clutch tension, the following procedure
should be used:
1. Remove the clutch cover and
loosen the screw in the large
hex nut on the front of the
clutch. Turn the nut in to in-
crease tension and out to
reduce it. Then tighten the
screw.
2. If you do not intend to change the tension on the clutch very
often, you can fold over one of the metal tabs on the washer
between the nut and the body of the clutch so that it presses
firmly on the hex nut. You can, of course, alter the pressure on
the clutch at a later date by bending the tab back up, adjusting
the nut, and bending a different tab against the nut.
3. Remember that the clutch is put on the machine to protect your
cables! Therefore, do not tighten to the point where sections will
be damaged before the clutch slips.
GEAR REDUCER MAINTENANCE
The Model 88 has an oil capacity of 1.25 pints. The manufacturer of
the gear reducer recommends #2 EP oil when operating conditions
are between 15 and 60 degrees F, and #4 EP oil when operating con-
ditions are between 60 and 165 degrees F.
The Model 88 gear reducers are shipped with #4 EP oil. The oil
should be changed after the first 1,000 hours of use, and thereafter
every 12 months or 5,000 hours of use, whichever comes first. The
following steps should be followed for refilling:
1. Remove the Vent/Fill plug at the top of the gear reducer.
2. Remove the Level plug at the middle of the side of gear reducer.
3. Use a funnel or other device to add lubricant until it appears at
the side opening (Capacity: 1.25 pints).
SPECIAL OPERATIONS
FOLDING HANDLE
To make the Model 88 more compact, it is equipped with a folding
handle. By lifting up the sliding collars on each side of the handle,
you can fold it forward. When the handle is raised, the collars will
drop into position, locking the handle in place.
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.
5. Pull the machine back until slack is out of
the cable. Put the motor switch in for-
ward. Stand behind the machine and
press the air switch. Machine will move
toward drain opening. Allow cable to
work its way through drain by itself.
6. If you have difficulty getting the cable
through the trap, you can use the Cable
Feeding Tool (Cat. # CF).
Place air switch on the floor beside drain
opening. Press cable feeding tool so that it
pinches the cable against edge of pipe.
With motor switch in forward, step on the
air switch and run machine until cable
moves freely into drain.
MAINTENANCE
To keep your machine operating smoothly, it is essential that all bear-
ings and bushings be lubricated. Oiling moving parts is particularly
important where machine comes in contact with sand, grit and other
abrasive material.
CABLE MAINTENENCE
To get maximum service from your cables, be
sure that they are clean and well oiled. This not
only provides running lubrication but greatly
extends the life of the cables as well. Our
SNAKE OIL is ideally suited for this purpose,
since it not only lubricates the cables, it deodor-
izes them as well.
DO NOT ALLOW TOO MUCH SLACK IN THE CABLE
BETWEEN MACHINE AND DRAIN OPENING SINCE
THIS CAN CAUSE CABLE WHIPPING.
DISCONNECT FROM POWER SOURCE BEFORE
ADJUSTING CLUTCH TENSION!

7. When all but the last two or three feet of cable section have fed
into the line, stop the machine. If you are using the “G” connec-
tors, simply twist the knurled ring on the Cable Drive Coupler 90°
and detach the cable from the machine. If you are using the “L”
cables, disconnect the cable from the machine using the Cou-
pling Wrench.
8. If the cable begins to buckle or twist, stop by taking your hand off
the air switch. The motor will spin in the opposite direction and
relieve the twist. When you reach some resistance in the drain,
move the motor switch to reverse and run for several seconds.
Then switch to forward again. Allow cable to stop spinning before
going in other direction. Repeat until water starts to flow.
9. After drain is clear, retract the cable by putting machine in re-
verse and backing machine away from drain opening. Allow ca-
ble to move out of drain at its own rate. Disconnect sections as
they emerge from drain.
