c. Check that the machine hydraulics are
matched to the tractor hydraulics.
d. With the tractor at a low idle, slowly
engage the PTO.
e. Increase the engine speed until it is at
3/4 throttle.
f. Engage airlock hydraulics. Be sure
airlock is turning in the forward direction.
g. Operate the machine at 3/4 speed for 10
minutes to warm the system before
putting under a full load.
IMPORTANT
It is important to warm the hydraulic
system and the blower reservoirs before
going to the rated speed. The blower will
not "warm up" unless the product is
being conveyed.
h. Open the air-slide approximately 2
inches and insert into the grain. Operate
at this setting until the machine is warm
(10 minutes).
j. After the warm up period, bring the
machine to capacity.
i. Increase the engine speed to the
rated PTO RPM.
ii. Close the air-slide until the intake line
starts to pulsate. Open the air-slide
slightly to stop it from pulsing.
iii. Watch the glass door in receiver tank
to determine how the product is moving
through the machine(Fig. 4-16) The glass
can be covered but it should not be
stationary. If more of the product is being
drawn in than discharged, the product will
lay stationary against the window.
