•
Remove plug in jack and replace with sintered breather.
IMPORTANT: DO NOT
operate the hydraulic unit with the solid shipping plug in the oil fill hole or damage to the
hydraulic unit may occur.
•
Verify electrical supply if press is equipped with heated platens.
The CARVER Laboratory Press was carefully designed with a low center of gravity to remain stable under normal
operating conditions. For a permanent installation, hold-down bolts may be used to fasten the press to a workbench.
Holes are conveniently provided in the base directly in front of the columns for this purpose.
If the press is equipped with heated platens, verify the electrical supply and connect the press to the correct voltage
source. The correct operating voltage and current draw information is printed on the ELECTRICAL DATA TAG which
is located on the side of the press.
3.6 GAUGE INFORMATION
This
CARVER
press features a gauge union coupling for quick and easy alignment and interchangeability. While
holding the coupling swivel to keep it from turning, turn the gauge into the coupling swivel until finger tight and position
it for easy viewing by the operator. Hold the gauge in this position with a 15/16" open end wrench on the stem directly
under the gauge case, and using a second wrench, turn the coupling swivel counterclockwise until tight. If leakage
occurs after tightening the gauge into the union coupling swivel, an additional seal may be required. (See reference
drawing 110478B in the appendix.)
IMPORTANT: DO NOT
use more than two (2) seals at one time.
3.7 RAM FORCE CALCULATION
All
CARVER
gauges are calibrated for the specific ram diameter of the hydraulic unit. The Mini "C" and Model "C"
12-ton (107Kn) ram is 3.294 square inches (21.253 square cm) and the Model "M" 25-ton (223 Kn) ram area is 5.157
square inches (33.273 square cm). The standard gauge readings display the load, or force, in pounds as well as metric
tons applied between the platen and head of the press. Accordingly, all calibrations show the load in pounds-force
applied by the press to the material being pressed. For example: a 10,000 lb. (44480n) load applied to material having
an area of one square inch (one square mm) would be equal to a pressure of 10,000 lbs. per square inch (44480 Newtons
per square mm) applied to the material. Or, if the material being pressed has an area of four square inches (258.08
square mm) a 10,000 lbs. (44480 Newton) applied load would be equal to 2,500 lb. per square inch (172.35 bar) on the
material.
EXAMPLE: 10,000 lbs. FORCE (44480 Newtons) = 2,500 PSI (172.35 bar)
4 square inches (258.08 square mm)
CARVER
gauges are highly sensitive, precision instruments. Care should be taken to avoid sudden decompression,
shock loading, over-pressurization, etc., which will result in damage to the gauge and void the warranty.
A variety of standard gauges are available with different calibrated ranges. The standard gauge provided with your press
is calibrated for full press tonnage. If an additional gauge is required, for a lower operating range, a CARVER 2096CE
Two-Gauge Manifold will permit simultaneous mounting of two separate gauges.
