Operation; Maintenance And Service - Enerpac VLP-Serie Anweisungs- / Reparaturbogen

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 performance do not
expose equipment to temperatures of 150°F [65°C] 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
inject.eps
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
bdyhit.eps
severe personal injury.
WARNING: BE SURE SETUP IS STABLE BEFORE
LIFTING LOAD. Cylinders should be placed on a
flat surface that can support the load. Where
applicable, use a cylinder base for added stability.
Do not weld or otherwise modify the cylinder to
stblty.eps
attach a base or other support.
Avoid situations where loads are not directly
centered on the cylinder plunger. Off-center loads
produce considerable strain on cylinders and
plungers. In addition, the load may slip or fall,
danger.eps
causing potentially dangerous results.
Distribute the load evenly across the entire saddle
surface. Always use a saddle to protect the plunger.
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
sman.eps
properly and withstand high loads.
3.0 INSTALLATION/MOUNTING (SEE FIGURE 1)
WARNING: Install the appropriate safety equipment (e.g.
guards or control devices) as required for your specific
application.
3.1 Mounting the Bench Press
danger.eps
Mount the press using the four mounting holes located in the
bracket. See Figure 1 for mounting dimensions.
The bench press is suitable for use in the vertical or horizontal
position.
WARNING: Mount the press firmly. If not mounted in a
stable position, the press may tilt, and could cause
serious personal injury or equipment damage as a result.
danger.eps
3.2 Mounting the Cylinder
Place the cylinder in the mounting block and tighten.
3.3 Hydraulic Connections
1. Connect the hose from the pump to the cylinder.
2. Tighten all couplers and fittings.
NOTE: Use 1 1 ⁄ wraps of teflon on the NPTF threads, leaving
2
the first complete thread free of tape to ensure that pieces of
tape do not enter the hydraulic system, causing leakage or
damage.

4.0 OPERATION

IMPORTANT: The frames of the workshop presses are exclusively
designed for pressing applications only. Do not use the workshop
presses for pulling applications. For information regarding presses
designed for pulling applications, please contact ENERPAC.
For complete operating instructions refer to the instruction sheets
included with each pump and cylinder.
IMPORTANT: It is mandatory that the operator has
a full understanding of all instructions, safety
regulations, cautions and warnings before starting
read.eps
to operate any of these high-force tool equipment.
4.1 Advancing and Retracting the Cylinder
On hand pump (P142) close the release valve and raise and lower
the pump handle to advance the cylinder to the desired position.
4.2 Air Removal
Advance and retract the cylinder several times avoiding pressure
build-up. Air removal is complete when the cylinder motion is
smooth.

5.0 MAINTENANCE AND SERVICE

Regularly inspect all components to detect any problem requiring
maintenance and service.
1. Replace damaged parts immediately.
2. Do not exceed oil temperature above 140° F [60° C].
3. Keep all hydraulic components clean.
4. Periodically check the hydraulic system for loose connections
and leaks.
5. Change hydraulic oil in your system as recommended in the
pump instruction sheet.
6. Periodically check the press frame to make sure all bolts are
tight and frame parts are undamaged. Immediately replace
worn or damaged parts with genuine Enerpac parts. For repair
contact your nearest authorized Enerpac Service Center.
