UIDELINES
Sukup Fastir machines benefit in-bin drying by:

Eliminating overdried grain layers. Stirring
mixes grain throughout bins.

Drying faster. Stirring allows the use of higher
drying temperatures.

Increasing drying capacity. Stirring loosens
grain and allows increased airflow through it.
As the machine mixes and loosens bottom layers of
grain that are easily overdried, grain may be heated
to higher temperatures to achieve faster drying rates
without any of the typical effects of overdrying.
I.
Operation Procedures
1 Start machine when grain is about 30”, or one
ring, deep.
1.1
Note
: Do NOT wait to start machine when
grain bin is nearly or completely full.
1.2
Note
: When drying grain, center roof
opening should be open to release
additional moisture from bin.
2
Never turn off machine while drying grain or
when continued filling will take place . In
natural air drying or low temperature drying, do
not shut machine off until grain is dry.
3 In situations where a multiple-auger machine is
used and drying of one bin of grain will take
longer than four weeks, operate stirring machine
intermittently to reduce grain damage.
3.1
Note:
The amount of time for which machine
should be operated can be determined
using the number of augers and size of bin.
Contact Sukup Manufacturing Co. customer
service for suggestions.
4 Do not overfill bin. Filling must be stopped
when distance between top of grain mound and
crosstube reaches 18” to prevent belt and motor
failure. Filling above this point voids
equipment warranty.
5 Use probe to determine moisture content of
crop. When grain first tests dry on the top, grain
throughout entire bin may not necessarily be
dry. Remember, the Sukup stirring machine was
designed to move dry grain off the bottom and
bring it to the top.
6 After grain has dried, shut off heater. Cool
grain and continue stirring . Ensure grain is
thoroughly cooled before shutting off fan.
Continue stirring for an additional 48 hours.
6.1
Note
: Sukup Manufacturing Co. also
recommends periodically running stirring
machine during winter months if grain is not
frozen.
II.
Restarting Fastir Machine
Note
: Shutting off machine allows grain to “set
up” around augers during inactivity. If machine
has been idle for more than two days, take care
when restarting it by using the following steps:
1 Support carriages and prevent distortion of
crosstube by setting boards on top of grain as
shown in Figure 41 .
Figure 41 - Carriage Support Setup During Machine Restart
2 Before power is applied, loosen down augers by
turning clockwise.
3 For 230V Units Only: Unplug all motors and start
each individually beginning with motor nearest to
center of bin.
4 Remove boards below carriages before
restarting.

Fastir Maintenance
Check the following items at the beginning of each
drying season:
 Belts aligned and in good condition
 Shields securely in place
 Electrical connections tight and insulated
 Gearmotor and shear pins in good condition
 Down augers not bent, worn out, or otherwise
in need of replacement
 Locking collars tight on bearings
 Electrical cords secured out of way of all
moving parts
 All bolts and nuts tight
 Hairpin clips inserted through holes on ends of
motor mount rods.
 All safety decals in place and in good
condition. See page 7 .
