MAINTENANCE
Your MaxiMixer will be delivered, fully lubricated and set up to all drive component installation
specifications. During the break in of your new MaxiMixer, it is recommended that a complete
daily inspection of all drive components be carried out. Throughout the life of your Maximixer, a
complete inspection of all drive components, fasteners, auger knives and shields should be
carried out during scheduled lubrication times. Wore or damaged parts must be replaced, loose or
misaligned parts must be adjusted and tightened to assure proper operation and life of
components.
WARNING: Always shut off engine, set parking brake, remove the key and
wait for all motion to stop before attempting to adjust, lubricate, service or
setup this machine!
CHAINS
Discharge Conveyor Chain
A. The conveyor chain will loosen up some during the first few hours of operation and over the
life of the discharge. Lift a flight near the center of the table. It should move about an inch
off the floor. Remember when tightening the chain to move both take ups the same distance
so the conveyor chain runs straight along the length of the discharge.
Oil bath Roller Chain and Sprockets
Chain Tension
B. Be sure it is tensioned adequately to prevent tooth jumping (ratcheting) under the most severe
load conditions, which the drive will encounter during operation.
C. Adjust spring tightener, to eliminate any slack in roller chain, by moving S-hook along
tightening chain to increase tension on spring.
Drive Alignment
D. Any degree of sprocket misalignment will result in some reduction of chain life.
Misalignment of all roller chain sprocket drives should not exceed 1/4 degree or 1/16” per
foot of linear distance. Misalignment should be checked with a good, straight edge tool. The
tool should be applied from the driver to driven, and then from the driven to driver sprockets
so that the total effect of parallel and angular misalignment is taken into account.
E. Drive misalignment can cause premature sprocket and chain wear. Extreme case may result
binding of chain and drive failure. Alignment of sprockets, using shims and the adjusting
screw on the jackshaft, is critical for proper operation of your MaxiMixer.
