HOW TO EXCHANGE DRUMS
1. Remove belt guard by loosening the knob above the motor.
2. Push the motor down far enough to slide V-Belt off drum.
3. Remove the cutter and connecting screw from the cable end.
4. Unscrew knob behind the front post and pull Power Cable Feed
off the machine.
5. With one hand on the cable, loosen the knob on the front post
cap and open the cap. The Flexitube will spring up out of the post
cap. Remove the Flexitube from the cable.
6. Unscrew the drum retaining bolt in the center of drum and slide
the drum off the shaft and lift it out of the way.
7. Reverse procedure to install drum.
8. To reinstall the Flexitube, pull about 12 inches of cable out be-
yond the frame, then guide the Flexitube, spring end first, into the
front post cap.
9. Position the Flexitube so that the hole in the bushing fits over the
locating pin in the base of the front post clamp. Make sure the
Flexitube bushing does not protrude beyond the front post clamp.
10. From the outside of the front
post, push the cable down
with one hand to secure the
Flexitube in position within
the clamp, then close the cap
and tighten the knob with the
other hand.
MAINTENANCE
To keep your machine operating smoothly, it is essential that all bear-
ings 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
directly 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.
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, cover screws, top cover, spring,
ball bearing and ball bearing holder. Note the positioning of these
parts to ease re-assembly. Remove the swing pin from the car-
rier. The top roller assembly can now be removed.
2. Remove the end cap screws, end caps and thrust washers from
the bottom housing cylinders. Remove swing pins from carriers.
The bottom roller assemblies 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-
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
together 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.
HOW TO INSTALL CABLES IN DRUM
1. Connect the male end of cable to
the drum connecting cable al-
ready attached to drum.
2. Remove V-Belt
3. Be sure the cable goes into drum
as shown in the diagram or cable
will tangle in drum.
4. Replace V-Belt after cable is
installed.

NOTE:
The cable must lay in the drum in the correct direction or it will
tangle in the drum.
