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.
5. The Feed Roller Axle should then be inserted through the same un
-threaded Axle hole and should continue to be guided through the
Spacers and Bearings to the threaded Axle hole on the other side
of the Carrier.
6. Securely tighten the Axle to the Carrier with a 3/16" allen wrench.
TANGLED CABLE
If a cable loops over itself in the drum/cage, it will not feed properly.
Remove and reload the cable to restore function. If the cable kinks, it
is evidence of abuse and results from the use of too much pressure or
use of the wrong size cable for the line. Do not force the cable — let
the cutter do the work.
