3. OPERATION
3.5B Loading Procedure
When loading material into the hopper,
keep the bucket as low as possible (fig.
S0010). Allow the material to slide down
the high side of the hopper plate onto the
top screen deck.
Check tailings for size. If you find good
material mixed in with the tailings, try
slowing the feed rate (dump) into the hop-
per.
Dumping the material further down the
deck wastes processing area (fig. S0011).
This will allow good material to flow off
with the tailings.
Use extra care when placing large
heavy objects on the top screen deck. Make
sure smaller material is in front of the load
before lowering onto the top screen deck.
This will provide some cushion effect.
Never drop large heavy objects directly
onto the top screen deck (fig. S0012).
Immediate damage to the wire screen cloth
or shaker assembly may occur.
Keep an eye on tailings and finished
product. Do not allow to build up around
the shaker deck area. Retrieve product
before excessive build up around the shaker
area.

Large objects may roll uncontrollably off

damage to the machine.
