4.8 OPERATING (cont'd)
5. Starting Machine (cont’d)
e. Slowly engage the PTO/Clutch control to
the drive system. (Fig. 4-8 )
f.
Increase engine speed until it is at
3/4 throttle.
g. Engage airlock hydraulics. Be sure airlock
is turning in the forward direction.
h. Operate machine at 3/4 speed for 10
minutes to warm system before putting
under full load.
IMPORTANT
It is important to warm the hydraulic
system and blower reservoirs before going
to rated speed. The blower will not "warm
up" unless product is being conveyed.
i. Open airslide approximately 2 inches and
insert into the grain. Operate at this
setting until the machine is warm (10
minutes).
j. After warm up period, bring machine to
capacity.
i. Increase engine speed to rated RPM.
ii. Close airslide until the intake line
starts to pulsate. Open slightly to stop
pulsing.
iii. Watch glass door in receiver tank to
determine how the product is moving
through the machine. The glass can
be covered but it should not be
stationary. If more product is being
drawn in than discharged, the product
will lay stationary against the window.
6. Airlock Speed:
Refer to the Table 2 as a guide
for setting the airlock speed. Use the
flow control to adjust the speed and
count the revolutions using the arrow on
the wheel. It may be necessary to
experiment to determine the best
speed.
