Troubleshooting procedures
ET4001P-002 electric pump
Step 1: Check – Look for fuse,
loose wire connections, switch
malfunctions or damaged cord.
Check for proper installation of
a 220 volt circuit.
Step 2: Check oil level – after
assembly and system has
been purged of air, the fluid
level should be½" from top of
reservoir. Clean, anti-wear type,
having a 300 SSU/100˚ hydraulic
oil is recommended (ISO 32 or
SAE 10W). Oil is needed to:
1. Transmit power easily
through system
2. Lubricate moving parts
3. Provide seal clearances
between parts
4. Cool or dissipate heat
Step 3: Clean or reset relief
valve – a 6,000 psi pressure
gauge, a 5/16" Allen wrench,
a 1" socket and a screwdriver

are required. Remove cap from
relief valve. Remove adjustment
screw, spring and ball. Ball
should be attached to spring.
Check ball and seat for possible
scoring. Replace spring and ball
in cavity. Insert a small punch
through spring against ball. Give
punch a moderate tap to seat
ball. Return adjustment screw
to original position making sure
adjustment screw is at least one
turn from bottoming. Remove
1/4" NPTF plug from port above
check valve and install a 6,000
psi pressure gage. With 6,000
psi pressure gauge in place,
operate unit to full crimping
position. Gauge should read
approximately 5,000 psi. To
raise setting, turn screw inward
(clockwise); to lower, turn screw
outward (counterclockwise) in
¼ turn increments. After each
adjustment, recycle and read
gauge for proper setting. Run
a cycle of the crimping system
for final gauge reading before
removing gauge and reinstalling

Step 4: Shuttle valve –
If the shuttle valve is in a closed
position and the ET4001 pusher
will not retract, it may be helpful
to tap the shuttle valve cap
several times to dislodge any silt
that may be causing the stem
to bind. If this does not free the
valve and allow the pusher to
retract, use extreme caution
prior to proceeding with shuttle
valve removal as the system is
still under pressure. It may be
advisable to relieve pressure at a
hose connection to avoid an oil
bath. After pressure is removed
from system, remove cap and
valve cartridge. Soak cartridge
in a PETROLEUM BASED
SOLVENT ONLY (clean Stoddard
solvent). Do not use Triethene,
gasoline or paint thinner as
they will damage the O-ring
seals. If cartridge disassembly is
required use care in removing
stem as it has a .0005 metal seal
fit. Rotate stem in solvent and

push from seat end to remove
from cartridge. Do not lose the
loose ball. Wash parts in clean
solvent and examine for any
surface markings. If necessary,
polish with a fine crocus cloth.
After final cleaning, reassembly
cartridge. Shake cartridge and
check for free movement of ball
and stem. Replace cartridge
if not functional at this point.
Reassemble shuttle valve into its
cavity and check crimping cycle
prior to using system.
! IMPORTANT: Pressure
must be relieved from system
before disconnecting hose,
installing gauge or removing
valves from pump.
