READ THE FOLLOWING BEFORE WELDING ON THIS MIXER/FEEDER
When welding on your mixer/feeder, do not allow the current to flow through the ball
bearings or the roller chains. Ground directly to the item being welded.
Always disconnect the scale instrumentation from the weigh bars or load cells and the
power source. Be sure the current does not pass through weigh bars or load cells or scale
indicator. The alternator should always be disconnected if the mixer/feeder is not
disconnected from the towing vehicle.
CHAIN TENSION
All the single roller chain should be tightened to the point of .042” (1 mm) (dime)
clearance is reached between the coils of the 1-1/4” idler tension springs and .068” (1.7
mm) (nickel) clearance is reached between the coils of the 1-3/4” idler tension springs.
LOADING INSTRUCTIONS & PRECAUTIONS
A.
Do not add side board extensions to the mixer.
B.
Do not overload the mixer. Mixer capacity can be reached by weight or volume. By
volume, the rotor bars and wipers should always be visible at the peak of the rotor
cycle. If the rotor is completely submerged under the mix, mixing efficiency may be
reduced, spillage may occur, and damage to the mixer may result. Maximum capacity
by weight can be calculated by multiplying 28 pounds times mixer cubic foot capacity.
C.
Load molasses and/or liquid protein supplements first with mixer not running, then add
one (1) commodity ingredient before starting the mixer. For the shortest mixing time
and maximum mixing efficiency, these items should be added at the first of the loading
process.
D.
When adding minute supplements or medication in non-liquid form, these ingredients
should be loaded in the middle of the loading sequence.
E. RATIONS WITH GROUND HAY:
1.
Load molasses (or liquids) first with the mixer not running.
2.
Load one (1) commodity ingredient and start mixer.
3.
Finish loading commodities, silage, or ground hay. Loading ground hay after mixing
liquids with another commodity will prevent molasses hay balls.
NOTE:
These procedures may not work on all rations. Loading sequences may be
changed to give best possible mix.
ATTENTION:
F.
Never load the mixer from the right side (side opposite the discharge) with a front end
loader while the mixer is running.
