SAFETY PRECAUTIONS
2000 Autoflow
READ THESE INSTRUCTIONS
BEFORE OPERATION AND SERVICE
SAVE FOR FUTURE REFERENCE
Use Caution in the
Operation of this
Equipment
1. Read and understand the operating manual before trying to operate the
dryer.
The design and manufacture of this
dryer is directed toward operator
safety. However, the very nature of
a grain dryer having a gas burner,
high voltage electrical equipment
and high speed rotating parts, does
present a hazard to personnel, which
can not be completely safeguarded
against, without interfering with ef-
ficient operation and reasonable ac-
cess to components.
2. Power supply should be OFF for service of electrical components. Use
CAUTION in checking voltage or other procedures requiring power to
be ON.
3. Check for gas leaks at all gas pipe connections. If any leaks are de-
tected, do not operate the dryer. Shut down and repair before further
operation.
4. Never attempt to operate the dryer by jumping or otherwise bypassing
any safety devices on the unit.
Use extreme caution in working
around high speed fans, gas-fired
heaters, augers and auxiliary con-
veyors, which may start without
warning when the dryer is operat-
ing on automatic control.
5. Set pressure regulator to avoid excessive gas pressure applied to burner
during ignition and when burner is in operation. Do not exceed maxi-
mum recommended drying temperature.
6. Keep the dryer clean. Do not allow fine material to accumulate in the
plenum or drying chamber.
7. Use CAUTION in working around high speed fans, gas burners, augers
and auxiliary conveyors which START AUTOMATICALLY.
KEEP THE DRYER CLEAN
DO NOT ALLOW FINE
MATERIAL TO ACCUMULATE
IN THE PLENUM CHAMBER

owner. For a safe and dependable
drying system, follow the recom-
mendations within this manual, and
make it a practice to regularly in-
spect the operation of the unit for
any developing problems or unsafe
conditions.
Proper Use of Product

Take special note of the safety pre-
cautions listed above before at-
tempting to operate the dryer.
