4.10 OPERATION
14. Operating Hints:
a. Try to keep the hoses as full as possible to
have maximum capacity.
b. Keep the PTO driveline as straight as possible
to minimize the universal joint angles.
c. Pull the intake nozzle out of the grain and
empty the machine before changing trucks.
d. Maximum efficiency is obtained with large
airflow lines. Use the smaller rubber lines only
for final clean-up.
e. Route the lines to minimize bends and corners.
If a corner is necessary, use a large radius
elbow.
f. Operate only at the rated speed and never use
PTO adaptor shafts.
g. Keep the lines as short as possible to
minimize friction losses.
h. If long distance moving is required, push the
grain rather than pull the grain.
i. If long distance moving is required, use solid
metal tubing whenever and wherever possible.
j. If the airlock becomes jammed, use the
hydraulics to reverse the direction of the airlock
rotation and to clear the obstruction. Do not
reach in with your hands to clear the
obstruction.
k. When on top of the grain, do not push the
nozzle into the pile next to the feet. The suction
will pull the nozzle and the operator into the
pile. If the pile is deep enough, the operator
can be submerged under the grain and be
suffocated.
