KEEP AWAY FROM FIRE AND HEAT

Keep your equipment away from excessive heat
which tends to soften the packings. For best
performance, DO NOT expose equipment to
temperatures above 160 F.

ASSEMBLY

1. Remove SHIPPING PLUG from the 3/8"
NPT port and discard (refer FIGURE 1).
NOTE: THE PLUG IS STRAIGHT THREAD
TO PREVENT DISTORTION TO THE 3/8”
NPT THREADING.

2. Assemble hose or quick-disconnect coupling
directly to this port. Use a sealant or Teflon
to seal threads.

3. The reservoir is vented so there is no need
to open any air vents prior to using the
pump.

WORKING PRESSURE

The pump's maximum working pressure is
10,000 PSI (700 kg/cm 2). Make sure that all
hydraulic equipment such as rams, hoses, etc.
used with this pump is rated at 10,000 PSI
operating pressure.

HYDRAULIC CONNECTIONS

Never disconnect or connect any hydraulic

hoses or fittings without first unloading the
ram. Open the release valve counter­clockwise to assure that the system has
been depressurized. If the system includes
a gauge, double check the gauge to assure
pressure has been released.

All Simplex cylinders and tools are equipped

with quick-disconnect couplings. These
couplings ease the assembly of your system.
These couplings must be assembled by
hand. Wrenches or pliers should not be
required for this operation.

If couplings will not fully engage (refer to

FIGURE 2 for proper engagement), turn the
release knob counter-clockwise to release
any pressure that may have built up.

Threaded connections such as fittings,

gauges, etc. must be securely tightened and
leak free. DO NOT over tighten connections.
Connections need only be secure and leak
free. Over tightening can cause premature
thread failure.

OSESH

DO NOT DROP HEAVY OBJECT

S ON HOSE.
A sharp impact may kink wire strands on which
the strength of the hose depends. AVOID
SHARP KINKS IN HOSE. Never apply pre

ssure
when hose is swung in sharp curves or when the
hose is visibly kinked.

AUTION: Loose or cross threaded fittings

C
can be potentially dangerous if pressurized.
Never hold or stand directly in line with any
hydraulic connections while pressurizing.
Never grab, touch or in any way come in
contact with a hydraulic pressure leak.
Escaping oil can penetrate the skin and a
serious injury can result.
