MAINTENANCE
LUBRICATION
1. MOTOR: The grinder motor has pre-lubricated, sealed motor bearings.
2. ROLLER CHAIN AND DRIVE SPROCKETS: The main drive chain has been pre-lubricated at the
factory to protect it against dirt and moisture. Chain life will vary appreciably depending upon its
lubrication. The better the lubrication, the longer the chain life.
• ALWAYS Turn Off, Unplug Machine From Power Source and Perform Lockout/Tagout
Procedure to this Machine BEFORE Servicing.

• NEVER
Place Hands into Machine Input or Output Openings.
• NEVER Bypass, Alter, or Modify This Equipment in Any Way From Its Original Condition.

ROTATING GRINDING AUGER & ROTATING MIXING PADDLE
TO AVOID SERIOUS PERSONAL INJURY
Lubrication effectiveness will vary with the amount of lubricant and frequency of application. Ideally, a
lubricant film should always be present between the working parts. Manually lubricate the chain as often
as is needed
(possibly once a week).
NEVER
exceed three months without lubricating.
Lubricating just the outside of the chain does little good. Apply lubrication on the inside of the chain span
so that it will work through the moving parts and joints by centrifugal force as the chain rotates and
reaches the area where one surface “scrubs” another.
Recommended types of chain lubricant are those with Molybdenum Disulphide or Graphite added. Also
bonded lubricants such as Dow Corning Molykote 321R or equivalent are excellent for open chains. The
lubricant should be of a viscosity whereby it will “flow” somewhat and penetrate the internal working
sufaces. Thick stiff greases are of little value because they cannot work into moving parts of the chain.
a. Unplug mixer/grinder from power source and perform lockout/tagout procedures.
b. Remove rear drive or access cover.
c. Spray or brush lubricant on inside of chain, slowly and carefully turning the large sprocket by hand.
d. Reinstall rear drive cover.
3. THRUST BEARING: The thrust bearing is housed in an enclosed and sealed cover. The lubrication
effectiveness will vary with the amount of lubricant and frequency of application. Ideally, a lubricant film
should always be present between working parts. Manually lubricate the thrust bearing with a good grade
of bearing grease as often as is needed (possibly once a week). Never exceed 3 months without
lubricating.
