Introduction
This item is generally used with other Rice Test apparatus specifically to keep sample

and operates with a variable speed control up to 2400 VPMs for 230V/50Hz. 3,000 VPMs
for 115V/60Hz.
General Information
Inspection:
Your Rice Vibrating Table was thoroughly inspected before it was shipped and should be
ready to operate as soon as you have completed the set-up procedure. Notify Humboldt
Mfg. Co. or your local agent and file a claim with any carriers involved if you find any
damage to the machine.
Physical Specification:
Shipping weight:
12 lbs (5.4 kg)
Overall height: 15 ½"
Base dimension: 11" Diameter
Power supply:
H-1826.4F 230 V/50/60Hz
H-1826B 115 V/60Hz
Check that your machine has the correct voltage for your local supply.
Initial Installation
Set the machine base up at the place it is to be used in the laboratory and then decide
if you plan to operate the machine resting on the three rubber feet as supplied or
permanently connected through the extra mounting holes in the base. The mounting
holes are 3/16" diameter on a 10 1/8" diameter bolt circle.
Put your H-1820 Pycnometer with cover into place on the H-1826.4F or H-1826B by
sliding it through the top ring slot and into position under the top ring. If not already
engaged press down on the ring to compress the springs and hook the screw heads from
the latches into the keepers on the ring. Now try latching the ring down. If you can’t get
the latches down, or if they go down and are too loose to hold the ring down, you can
make a final adjustment by turning the latch screw(s) and re-tightening their nuts. The
proper setting is when the keepers are deflected downward slightly when latched. This
pressure on the keepers should hold the pycnometer in place when there is a vacuum
drawn on it.
Operation
The vibratory action is started by operating the on-off switch located on the front of
the base. Start the machine by raising the bat handle on the toggle switch to the “ON”
position.
CAUTION: Keep hands, clothing and other objects away from moving parts when the
machine is in operation.
Maintenance
The machine can generally be maintained by keeping it clean, correcting any looseness
that may occur and protecting the electrical cord.
