assembly. The unit incorporates extended upright rods in order to accommodate both
standard 4” or 6” asphalt compaction molds as well as the taller gyratory compaction
molds. Overall dimensions excluding pump 13” W x 6” D x 29” H (330 x 152 x 737
mm).
This equipment is designed to remove samples from molds and tubes and consists of
the following main components:
1.1 H-4150.2 - Pump Assembly.
1.2 H-4150.21 - Frame Assembly.
1.3 H-4155ED4 - 4” OD Ejector Disc.
1.4 H-4155ER4 - 4” Ejector Ring.
1.5 H-4155ED6 - 6” OD Ejector Disc.

Set Up
Remove the rubber covers from the quick disconnect fittings on the end of the
hose and on the cylinder.
Connect the hose to the cylinder by screwing together the quick connect.
Be sure to relieve the pressure in the hose by putting the lever on the pump valve
to the “return” position before connecting hose to cylinder.
Plug pump into correct outlet for the pump power rating.
Activate the pump with either the button in the handle or the button on the wired
remote.
If you activate the pump with the lever on the pump valve in the “return” position
it will push the sample out and the cylinder will immediately retract when the
button on the pump is released. To keep the cylinder in the extended position
move the lever on the pump valve to the “hold” position.
Operation
Place and attach the proper size ejection disc for the mold or tube onto the jack piston
rod and insert the matching ejection ring into the top casting using the key notches to
retain it by twisting approximately 30 degrees.
Place the mold with sample into the disk and raise the jack to bring the mold into
engagement with the top ring. Continue applying force by operating the jack handle to
push the sample from the mold.
