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.
WARNING: Only use hydraulic cylinders in
a coupled system. Never use a cylinder
with unconnected couplers. If the cylinder
becomes extremely overloaded,
components can fail catastrophically causing severe
personal injury.
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 by 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 DESCRIPTION
These hydraulically advanced work supports provide
additional support to avoid excessive movement,
vibrations, or deflection of the workpiece during
machining.
As alternatives, spring advanced work supports may
also be used as either air spring loaded or as air
advanced units by simply removing the internal
adjustable spring and attaching a low pressure air
line to the air breather vent port.

5.0 INSTALLATION
1. Locate the work supports at the lowest point of
the fixture's hydraulic system to aid in venting.
Work supports must be purged of air by cycling
several times and allowing air in the system to
vent at the highest point in the system.
2. Install the work supports by either threading into
the fixture, using the accessory jam nuts, or
bolting the flange onto the fixture. Mount the work
support so that the plunger is at the approximate
middle of its stroke when contacting the
workpiece in the fixture. If the work support is to
be hydraulically manifold mounted to the fixture
through the bottom port, the port screw plugs and
copper gaskets must first be removed (see item
B, Figure 2). Lubricate the provided o-rings and
install them (see Figure 2) in the counterbore
around the port prior to mounting and bolting
down the work support. Be sure that the o-rings
do not get pinched or damaged during this
mounting as leakage could result. To ensure that
the manifold mounting does not leak, provide a
fixture mounting surface with flatness within .003
inch (0.08 mm) and a surface roughness not to
exceed 32 uin. rms. (Ra 0,8).
