SAFETY FIRST
2.0 SAFETY ISSUES
Read all instructions, warnings and
cautions carefully. Follow all safety
precautions to avoid personal injury or
property damage during system operation. Enerpac
cannot be responsible for damage or injury resulting
from unsafe product use, lack of maintenance or
incorrect product and/or system operation. Contact
Enerpac when in doubt as to the safety precautions
and operations. If you have never been trained on
high-pressure hydraulic safety, consult your
distribution or service center for a free Enerpac
Hydraulic safety course.
Failure to comply with the following cautions and
warnings could cause equipment damage and
personal injury.
A CAUTION is used to indicate correct operating or
maintenance procedures andpractices topreventdamage
to, or destruction of equipment or other property.
A WARNING indicates a potential danger that
requires correct procedures or practices to avoid
personal injury.
A DANGER is only used when your action or lack of
action may cause serious injury or even death.
WARNING: Wear proper personal
protective gear when operating hydraulic
equipment.
WARNING: Stay clear of loads supported by
hydraulics. A cylinder, when used as a load
lifting device, should never be used as a load
holding device. After the load has been raised or
lowered, it must always be blocked mechanically.
WARNING: USE ONLY RIGID PIECES TO
HOLD LOADS. Carefully select steel or
wood blocks that are capable of supporting
the load. Never use a hydraulic cylinder as
a shim or spacer in any lifting or pressing application.
WARNING: Do not exceed equipment
ratings. Overloading causes equipment
failure and possible personal injury. The
vise is designed for a max. pressure of 700 bar [10,000
psi]. Do not connect the vise to a pump with a higher
pressure rating.
Never:set the relief valve to a higher
pressure than the maximum rated pressure
of the pump. Higher settings may result in
equipment damage and/or personal injury.
WARNING: The system operating pressure
must not exceed the pressure rating of the
lowest rated component in the system.
Install pressure gauges in the system to
monitor operating pressure. It is your window to what
is happening in the system.
CAUTION: Avoid damaging hydraulic
hose. Avoid sharp bends and kinks when
routing hydraulic hoses. Using a bent or
kinked hose will cause severe back-pressure. Sharp
bends and kinks will internally damage the hose
leading to premature hose failure.
Do not drop heavy objects on hose. A
sharp impact may cause internal damage
to hose wire strands. Applying pressure to
a damaged hose may cause it to rupture.
IMPORTANT: Do not lift hydraulic
equipment by the hoses or swivel couplers.
Use the carrying handle or other means of
safe transport.

CAUTION: Keep hydraulic equipment
away from flames and heat. Excessive
heat will soften packings and seals,
resulting in fluid leaks. Heat also
weakens hose materials and packings. For optimum
performancedonotexposeequipmenttotemperatures
of 65°C [150°F] or higher. Protect hoses and cylinders
from weld spatter.
DANGER: Do not handle pressurized
hoses. Escaping oil under pressure can
penetrate the skin, causing serious injury.
If oil is injected under the skin, see a doctor
immediately.
Avoid situations where objects are not
directly centered in the vise jaws. Off-center
objects can produce considerable strain on
vise. In addition, the object may slip or fall, causing
potentially dangerous results.
BE SURE SETUP IS STABLE BEFORE
CLAMPING. Vise should be securely bolted
to a flat, solid surface capable of supporting
the load. Do not weld or otherwise modify the vise
cylinder to attach a base or other support.
IMPORTANT: Hydraulic equipment must
only be serviced by a qualified hydraulic
technician. For repair service, contact the
Authorized ENERPAC Service Center in your
area. To protect your warranty, use only ENERPAC oil.
WARNING: Immediately replace worn or
damaged parts with genuine ENERPAC parts.
Standard grade parts will break causing
personal injury and property damage.
ENERPAC parts are designed to fit properly and
withstand high loads.
3.0 HYDRAULIC VISE OPERATING SAFETY
WARNING: Failure to observe the following
safety precautions and instructions may
result in serious personal injury or death.
• Always wear safety glasses before operating vise.
• Keep all body parts, including hands and fingers,
away from vise jaw clamping area during vise
operation. Failure to observe this precaution may
result in serious personal injury. See Figure 1.
• Small parts should be held with pliers or other suitable
tool when clamping an object in the vise jaws. If
necessary, use a magnetic jaw plate to assist with
holding the object in place until the jaw is retracted.
• Never use your fingers to hold an item in place
during clamping. Use a pliers, magnetic clips or
other suitable tools.
• Center the object in the jaws so that the force will
be as evenly distributed as possible. Be certain that
any odd shaped objects are positioned securely, so
that they do not fly out when the jaw is retracted.
• The moving vise jaw is spring tensioned, and will
extend immediately when pressure is relieved. Stay
clear of the area in front of the jaw. Before relieving
pressure, be certain that no personnel are in front
of the jaw.
• The hydraulic vise offers three to five times more
clamping force than a standard bench vise. For this
reason, exercise care to ensure that objects are not
accidentally crushed and damaged in the vise.
• Always shut-off pump and disconnect hydraulic
hose from pump when finished using vise. Do not
leave vise connected and unattended.
WARNING: CRUSH AND
PINCH POINT HAZARD
• Never place fingers or hands in vise!
• Do not use fingers or hands to
position objects in vise!
Figure 1 - Crush and Pinch Point Hazard.
4.0 INSTALLATION
4.1 Pump Requirements
A 10,000 PSI [700 bar] hydraulic pump equipped with
a pressure release valve is recommended for use with
the vise. If desired, a pump equipped with a three-way
control valve (allowing oil flow back to tank) may also
be used.
Always check the pump hydraulic relief valve setting
before connecting the vise. The relief valve setting
must not exceed 10,000 PSI [700 bar].
If an air-powered hydraulic pump is used, an air
regulator must be installed in the air supply line,
limiting the maximum hydraulic pressure to 10,000
PSI [700 bar].
4.2 Preparation for Mounting
Prepare the vise mounting surface as shown in
Figure 2. Three 0.61 inch diameter [15,5 mm] holes
must be provided for the swivel base mounting bolts.
An additional 1.5 inch [38,1 mm] diameter hole must
be provided for the hydraulic hose.
Install the vise only on a solid mounting surface, such
as a workbench, rigid platform or structural support
member.
The mounting surface must be capable of supporting
the combined total weight of the vise, the swivel
base, and the object to be secured. It must also be
capable of withstanding any external forces that could
be transmitted to the vise and/or the object being
secured.
Note: The total weight of the vise and hydraulic hose
is approximately 66 pounds [29,9 kg].

Verify that there will be adequate clearance, so that
the vise jaw can be fully extended to its maximum
8 inch [203 mm] opening without contacting other
objects. Also, verify that there will be sufficient room
to rotate the vise on the swivel base.
The vise is intended primarily for horizontal mounting,
However, if desired, the vise can also be mounted
vertically.
4.3 Vise Installation
Install the vise as described in the following steps:
1. Assemble the vise to the swivel base as shown in
Figure 3. Tighten the locking nuts hand tight.
2. Route the hydraulic hose through the 1.5 inch
[38,1 mm] diameter hole in the support surface.
IMPORTANT: One end of the hose is connected to
the vise at the factory prior to shipment. To prevent air
entry, do not disconnect the hose from the vise.
3. Firmly secure the vise and swivel base to the
support surface as an assembly. Use three 39/64"
bolts (user-supplied).
4. Rotate the vise to the desired position on the
swivel base. To change vise position, loosen each
locking nut about one full turn and rotate the vise
to the desired position. After making adjustments,
retighten the locking nuts to secure the vise.
4.4 Hydraulic Connections
Refer to Figure 4 for hydraulic connection diagrams.
A 10,000 PSI [700 bar] rated thermoplastic hydraulic
hose is supplied with the vise.
The hose end contains an Enerpac CH-604 male
quick-disconnect coupler.
A female quick-disconnect coupler (Enerpac CR-400
or equivalent) must be installed in the pump hydraulic
outlet.
If the pump is not equipped with a gauge, install a
0-10,000 PSI [0-700 bar] hydraulic pressure gauge
between the pump outlet and the hydraulic hose.
IMPORTANT: Be sure that all couplers are properly
connected. Loose or partially connected couplers will
block the flow of oil between the pump and the vise.
5.0 OPERATION
WARNING: Read and understand the
precautions contained in Section 3.0,
Hydraulic Vise Operating Safety, before
operating the vise. Failure to observe the precautions
in Section 3.0 may result in serious personal injury or
death.
Note: On vented pumps, be sure that the vent/fill cap
is in the “vent” position to allow reservoir venting. If
a vent screw or plug is used, be sure it is loosened
(open).
Operate the vise as described in the following steps:
1. To retract (close) the vise jaw, close the pump
release valve and operate pump.
2. To lock (hold) the vise jaw in position, stop
operating the pump, but keep the pump release
valve closed.

Figure 5 - Air Removal.
Position vise upside-down.
Raise pump above vise.
Cycle jaw at
least 3 times.
Operating Characteristics:
• Increasing the hydraulic flow will cause the jaw to
close faster.
• If using an air-powered hydraulic pump, increasing
the air flow will cause the jaw to close faster.
• Increasing the hydraulic pressure will result in
greater clamping force.
• 1000 psi [70 Bar] of hydraulic pressure will provide
approximately 650 pounds [2,89 kN] of clamping
force. Note: Actual clamping force provided will vary
depending on condition of vise, amount of use and
other factors.
CAUTION: Always monitor the hydraulic
pressure gauge when operating the vise.
Excessive clamping force can damage
and/or crush objects placed in the vise.
6.0 MAINTENANCE
WARNING: Always relieve pressure and
disconnect pump from vise before
performing any inspection, maintenance
or repair procedures.
1. Use only Enerpac hydraulic oil with the vise. The
use of any other oil may void your warranty.
2. Cover hydraulic fittings with dust caps when the
hydraulic hose is disconnected.
3. Keep vise external surfaces clean.
4. To help ensure smooth operation, periodically
lubricate the sliding tube of the vise with grease.
5. Periodically inspect the jaw wear plates for
damage or excessive wear. Replace as required.
6. Periodically inspect the vise for loose or damaged
components. Make repairs and/or replace parts
as required before operating vise.
7. Store the vise upright on a firm surface, in a cool,
dry place to prevent seal distortion.
7.0 AIR REMOVAL
If the vise jaw does not retract smoothly, this may be
caused by air trapped in the pump, hydraulic hose
or vise cylinder. Refer to the following steps for air
removal instructions:
1. Remove the vise from the swivel base.
2. Place the vise on the ground and position it
upside-down. See Figure 5.
WARNING: Vise jaw will move during the
following steps. Keep fingers, hands and
all other body parts away from the vise jaw
clamping area.
IMPORTANT: The following steps are intended only
as a guide. Pump venting arrangements and air
purging procedures will vary, depending on pump
model and type. Refer to your pump's instruction
sheet for additional information.
