This section is designed to help you remedy problems if unsatisfactory operation occurs. If you are unable to determine
and correct the trouble, consult one of our authorized dealers.
CAUTION: NEVER ATTEMPT TO LUBRICATE, ADJUST, OR OTHERWISE SERVICE THIS MACHINE UNTIL THE
POWER HAS BEEN DISCONNECTED, LOCKED OUT AND ALL MOTION HAS STOPPED.
PROBLEM - EXCESSIVE ROLL WEAR
1
POSSIBLE CAUSE - Overfeeding, with excess grain continually sliding off the top of the rolls creating friction and
excessive roll wear.
SUGGESTED REMEDY - Keep rolls “hungry”. Adjust hopper gate to feed in only the amount of grain the rolls will take
away. Usually, overfeeding is not the cause for wear on deep-grooved rolls.
2 POSSIBLE CAUSE - Crushing abrasive materials other than grain.
SUGGESTED REMEDY - Mills are designed to be used only on grain, or other similar textured materials.
3 POSSIBLE CAUSE - Foreign matter, such as metal, going between the rolls.
SUGGESTED REMEDY - Periodically check the magnetic grate for metal, nails, bolts, etc. and remove as necessary.
4 POSSIBLE CAUSE - Gravel in the grain.
SUGGESTED REMEDY - Sand and small gravel is difficult to remove from grain because of similar sizes as grain.
Larger gravel and small rocks can be removed by screening with wire hardware cloth on a frame mounted in the
hopper.
PROBLEM - MILL IS HARD TO START
1
POSSIBLE CAUSE - Grain between rolls.
SUGGESTED REMEDY - Close hopper gate, and separate rolls to allow grain to fall through. The best remedy is to
make a practice of closing hopper gate before stopping mill so no grain is left between the rolls.
PROBLEM - EXCESS VIBRATION
1
POSSIBLE CAUSE - Uneven flow of grain into the mill.
SUGGESTED REMEDY - Eliminate “surging of grain” into the mill as much as possible.
2 POSSIBLE CAUSE - Excess RPM.
SUGGESTED REMEDY - Recommended nominal operation speed of 1750 RPM (motor).
3 POSSIBLE CAUSE - Roll bearings worn or defective.
SUGGESTED REMEDY - Replace bearings.
4 POSSIBLE CAUSE - Feed rate is too fast for current roll spacing.
SUGGESTED REMEDY - Slow down the feed rate, or change the roll spacing. IMPORTANT: Changing roll spacing will
affect feed particle size.
5 POSSIBLE CAUSE - Loose bolts on bearings or mill.
SUGGESTED REMEDY - Check for loose or missing hardware and replace or secure.
