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 carri-

er. 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.

TANGLED CABLE 

If a cable loops over itself in the drum, it will not feed properly.  Re-

move 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.  

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.
