HOW TO USE J-DRUM
(Optional. Cat. No. MR-250)
The J-Drum holds 50 feet of 1/4" or 5/16"
cable to be used when you need to clear
smaller 1-1/4" to 2" lines. These cables
have a basin plug head that can be spun
through most strainers. (See Cable Applica-
tion Chart—Table 1)
DISCONNECT MACHINE FROM POWER SOURCE
BEFORE INSTALLING CABLES OR DRUMS!
1. To install cable, open chuck jaws fully so that cable will pass
through easily.
2. Slide the back end of the cable (opposite to the end with basin
head) through spout and into the drum. The cable will be easier to
install if you bend the last inch of cable at a 45 degree angle.
3. When working through difficult stoppages or tight bends, tighten
the chuck to provide more torque and to prevent the cable from
tangling in the drum.
4. Clean and lubricate chuck regularly to prevent corrosion.
HOW TO INSTALL POWER CABLE FEED
(Optional. Cat. No. PO-MR)
DISCONNECT MACHINE FROM POWER SOURCE
BEFORE INSTALLING POWER CABLE FEED!
1. Put the feed control lever in the
neutral (middle) position, then
loosen the feed tension adjustment
knob until the top feed roller lifts out
of the way.
2. Pull three feet of cable from drum/
cage. Remove cutter and connect-
ing screw from cable.
3. Fully loosen upper clamp knob on the feed support bracket and
snap the clamp over the Mini-Rooter's upper frame. Center the
feed over the drum spout and slide the cable through the feed
rollers. Then moderately tighten the knob.
4. Loosen the two lower clamp cap screws to allow the clamps to fit
over the lower frame. Note that the "short" clamp half should be
closest to the floor.
5. It may be necessary to loosen and re-adjust the upper tube length
to get the correct fit. Loosen the two set screws in the upper tube
and slide the assembly to get the best fit.
6. When alignment is correct, tighten the lower clamp set screws.
Screws should not be fully tightened. Make snug only so that the
bracket is able to pivot.
7. Fully tighten the upper tube set screws.
8. Test the bracket by loosening the knob and swinging the feed
assembly outward. It should disengage and swing smoothly.
9. Swing the feed assembly back and the clamp should snap into the
locked position. Tighten the knob to secure the feed for operation.
Do not attempt to use or transport the unit unless the upper clamp
knob is tightened.
WHEN USING THE POWER CABLE FEED
NEVER OPERATE MACHINE WITHOUT THE GUIDE
TUBE IN PLACE!
MAINTENANCE
DISCONNECT MACHINE FROM POWER SOURCE
BEFORE PERFORMING MAINTENANCE!
To keep your machine operating smoothly, it is essential that all bear-
ings and distributor tube 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. Some users periodically pour oil di-
rectly into the drum. Then, as the drum
turns, the cables get complete lubrication.
Our SNAKE OIL is ideally suited for this
purpose, since it not only lubricates the
cables, it deodorizes them as well.
POWER FEED MAINTENANCE
Keep feed free of excessive soil and grit. It is recommended that the
feed be flushed with fresh water followed by a light oiling of the mov-
ing parts. No disassembly is normally required. Failure to feed can
usually be traced to the following possibilities:
DIRT ACCUMULATION
Over time, dirt can harden enough to stop roller rotation. Flushing with
water followed by liberal oiling can usually restore function. If disas-
sembly is required, proceed as follows:
1. Remove the feed pressure knob, springs and spring plunger. Note
the positioning of these parts to ease re-assembly. The top roller
can now be removed.
2. Remove the snap rings and thrust washers from the bottom hous-
ing cylinders. The bottom rollers can now be removed.
3. Re-assembly is done in reverse order.
DAMAGED ROLLER
Excessive use may wear a roller to the point of failure. It is recom-
mended that all three rollers be replaced at the same time (Cat # PO-
MR-703). The replacement roller is an assembly consisting of one
Feed Roller, two Feed Roller Bearings, and two Bearing Spacers.
Note: The Bearing Spacers must be installed between the Carrier
and each Feed Roller Bearing (as illustrated below) in order to
ensure proper operation and to obtain maximum Feed Roller life.
To Replace the Feed Roller Assembly:
1. Remove the Feed Roller Assembly by unscrewing and removing
the Feed Roller Axle.
2. For convenience, the components are assembled and wired to-
gether at the factory. Before attempting to install the assembly,
hold the assembly together and remove the wire.
3. While still holding the Feed Roller Assembly together, insert it into
the slot opening of the Carrier.
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.
