6. Gathering Material:
a. Use the open end of the
bore to pick up the mate-
rial.
b. Use the tube or spread
wands to pick up material.
c. Several types of tubes or
wands are available to
use. The operator can
select the one most
appropriate for their
application.
7. Air Slide:
Each wand is designed with an
air slide on the tube that can be
used to control the amount of
air entering the machine along
with gathered material. Always
move the wand so that suffi-
cient air enters the system to
move the material and cool the
blower. Do not starve the
system for air.
DANGER
Do not place intake tube near feet
when standing on top of material.
Sufficient material can be re-
moved to draw operator and
intake tube into material. Sub-
mersion in material can cause
suffocation.
8. Nozzle Position:
Do not place the nozzle between your feet
when picking up a deep pile of granular
material. The nozzle can pick up sufficient
material to draw the operator into the pile and
suffocate them. Always pick up material away
from nozzle.
