The pump on your machine is an SPX Model B
The control valve is a 4 position 3 way valve
built by SPX
This pump is equipped with an external dump
valve, sight glass with temperature gauge, and
an oil drain plug
The Pump uses TURBINE GRADE HYDRAULIC FLUID
ALTRA R&O 150 OR BETTER as the fluid of choice.
The reservoir should be ¾ full of fluid.
The vent is located in the Red colored plug
located on the back side of the reservoir.
This pump is a 15 minute duration unit. Please
turn off the pump motor whenever the machine
This will prolong pump life and minimize fluid
The Valve (See figure 2, figure 3, & figure
The valve contains a 4 position lever and a
star shaped flow control knob, and an external
The 4 position lever is labeled RETRACT, HOLD,
METERED ADVANCE, RAPID ADVANCE. (See Figure
You should only use this valve in the METERED
ADVANCE or RAPID ADVANCE positions. Use the
dump valve to release the load or pressure from
the machine. (Figure 3)
The lever on the right side of the valve is
the pressure/release lever or DUMP VALVE. (Figure
In the upright position (with the lever straight
out) the pump will Build pressure. (Figure 4)
In the down position (with the lever facing
down) the pump will release pressure and allow
the piston to retract. (Figure 3)
The lever on the left is the rapid advance/controlled
rate lever. (Figure 2)
With the knob pulled toward the star shaped
knob, the pump is in rapid advance.
Note: This means the piston
will move rapidly. Care must be taken when using
the rapid advance function. The piston only
has 2 1/2 inches of stroke. If left in the rapid
advance position for too long, the piston will
overextend causing a release of oil from the
piston assembly. Contact CSI at 724-867-6664
if this occurs to prevent extensive damage which
would void your warranty.
The rapid advance lever is used only
to position the piston close to th sample for
zeroing purposes, or to preload the sample once
zeroing has been performed. Never use the rapid
travel position to test the cylinder to total
failure. This will provide inaccurate test results.
The stem in the center acts like a water spigot
(Figure 2). Counter-clockwise increases the
rate of force application per second. Clockwise
decreases the rate. Once the proper rate is
achieved, you can leave the stem at that setting
and the machine will continue to load at the
You are now ready to test your specimen.
