MAINTENANCE
To keep your machine operating smoothly, it is essential
that all bearings and distributor tube bushings be lubri-
cated. Oiling moving parts is particularly important where
machine comes in contact with sand, grit and other abra-
sive 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 recom-
mended that the feed be flushed with fresh water fol-
lowed by a light oiling of the moving parts. No disassem-
bly 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 disassembly is required, proceed as
follows:
1. Remove the feed tension 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 housing 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 recommended that all three rollers be replaced at the
same time (Cat # PO-MR-703).
TANGLED CABLE
If a cable loops over itself in the drum, it will not feed
properly. Remove and reload the cable to restore func-
tion. 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.
