Humboldt H-3625 Flow Table with Mold - Manual (Page 4)

Operation
Depending upon the model purchased operation are the following:
1. By hand (cranking clockwise).
2. By actuating the switch (on the motor line-cord) to the desired count or
3. By presetting and actuating the automatic counter. If the latter, see instructions
attached for the H-3614 Automatic Counter Kit.
Prior to an actual test raise and permit the table to drop a dozen times or more just
prior to use if it has not been operated in some time.
Perform a calibration test to check for satisfactory operation of the flow table using a
suitable calibration material.
Refer to the appropriate ASTM or AASHTO specification for conducting tests, e.g., for
testing the Air Content of Hydraulic Cement Mortar follow the procedure outlined in the
current issue of ASTM Specification C185.
CAUTION: Keep hands, clothing and other objects away from moving parts when the
machine is in operation.
Maintenance
The table top and vertical shaft must be kept clean and the vertical shaft lightly
lubricated with a light oil (SAE-10), which must not flow into the mating frame and
table top surfaces.
To facilitate easy starting and reduce wear apply a light film of oil to the crown of
the cam, being careful to keep it off of the mating frame and table top surfaces.
When the concrete is cured insert the proper ½ " (13mm) padding or pads under the
pedestal.
After mounting, tighten all fasteners (20 ft. lb. torque or 27 NM) and check to see the
able top is level along two diameters in both the raised and lowered positions.
