Grain Systems Unload Augers PNEG-1079 - Manual (Page 19)

5. Operation Procedures
PNEG-1079 6", 8" and 10" Vertical Bin Unload Auger 19
The auger may be operated at speeds from 500 RPM-750 RPM. Operating speeds of 650 RPM-730 RPM
are recommended to achieve rated capacity. Auger flight speed in excess of recommended speed causes
excessive wear. Do not attempt full load operation at speeds below 350 RPM as high torque requirements
may damage the auger.
Break-In Period
Any screw conveyor when it is new or after it sets idle for a season should go through a “break-in” period.
The auger should be run at partial capacity until several hundred bushels of grain have been augered. This
polishes the flighting assembly and tube. Once this is accomplished, the auger can be operated at full
capacity. The auger should not be operated empty except at start-up and during clean-out.
PTO Drive
Only use a tractor with 540 RPM power take-off. If the tractor output PTO shaft is operated at 540 RPM,
the auger will have a 540 RPM auger flight speed.
NOTE: The PTO driveline furnished with the auger is equipped with a “SPRING-LOCK” coupler at the
tractor end. This type coupler is spring loaded and will fit the standard 1-3/8" x 6" spline PTO
output shaft from a tractor.
The retaining balls of the coupler lock into the ring groove of the tractor PTO output shaft to prevent
inadvertent detachment. The PTO driveline is a pin stop-type; that is, the two (2) telescoping sections will
not separate. It is a good practice to operate the PTO driveline in as short a configuration as possible and
keep in line with the tractor as much as possible during operation.
Double check the following before adding power:
Engage PTO at a slow RPM to minimize shock loads. Then work up RPM to recommend speed.
Never operate the auger empty for any length of time, as excessive wear will result. If at all possible,
do not stop or start the auger under load, especially before the flight and tube have become well polished,
as this may cause the auger to “freeze-up”. (See break-in period
above .)
Before operating the unit, add #90 weight non-foaming oil to the gearbox until it
reaches the level check plug in the side of the gearbox.
CAUTION
CAUTION
Before starting the tractor, be certain power to PTO is OFF.
NOTICE
Be certain that the PTO driveline is securely attached to the auger and the tractor.
CAUTION
Use a PTO driveline with a rotating shield in good working order that can be turned
freely on the shaft.
NOTICE
Align PTO driveline with tractor.
