OPERATING INSTRUCTIONS
NOTE: Be sure to read these instructions completely before operating this pump. Failure to follow these
instructions may result in personal injury or damage to the pump. Safety and Operating instructions are
on the back page.
1. INTRODUCTION
Dirt - This will quickly ruin any hydraulic system.
Before hooking up a system, insure that couplings are
clean and free of foreign matter. Dirt, sand, etc. can
cause difficult assembly and premature wear to seals
and steel components of your hydraulic equipment.
After each use of the system, clean all couplings and
assemble all dust caps.
Air Bleeding - Air in a hydraulic system can be haz-
ardous because it is compressible. Before loading any
cylinder, air must be bled from the system.
With double-acting cylinders, the cylinder may be
purged by fully extending and retracting the unloaded
piston several times. (It is not necessary to invert the
cylinder.)
Air in the system can cause sluggish or hesitant action
of the piston when extending or retracting. When air
has been purged, cylinder action will be smooth and
uniform.
Air can enter your system in many ways, but the most
common is by inadequate usable reservoir capacity.
(Oil level drops below inlet and pump sucks air.)
2. ASSEMBLY
a). Remove two No. 87145 plugs from the 3/8"
NPT ports A & B located on both sides of the
directional control valve. (See figure 1).
b) Assemble hoses or quick-disconnect couplings
at these ports.

c). Connect hoses to cylinder or ram.
d). All Simplex cylinders are equipped with quick-
disconnect couplings. These couplings make
assembly of your system simple and quick.
These couplings must be assembled by hand.
If wrenches or pliers seem to be necessary for
assembly, you are doing something wrong. If
couplings will not fully engage (See figure 2 for
proper engagement), shift the directional con-
trol valve a few times to release any pressure
that may have built up.

e). The reservoir is not vented so there is no
need to open any air vents prior to using the
pump.
