• Non-synchronized lifting actions.
• Non-stable cylinder base support.
It is understood that some side load will occur in many
lifting situations. However, the user should do everything
possible to minimize or eliminate this condition.
The possibility of side load can be reduced by ensuring
that the cylinder base is located on a flat and hard
surface, parallel to the lifting surface and capable of
supporting the cylinder and the load without settling.
5. Operation
Operation procedures will vary, depending on hydraulic
pump type, valve configuration and other factors. For
detailed operating instructions and related information,
refer to the instruction sheet included with your pump.
Also follow the additional instructions and precautions
contained in sections 5.1 and 5.2 of this manual.
5.1 Operating Precautions
WARNING
Failure to observe the following instructions and
precautions could result in serious personal injury, oil
leakage and/or property damage.
• Advance the plunger slowly.
• Use extreme caution when using high oil flow
pumps with CULP Series cylinders. The plunger
may advance more quickly than expected.
NOTICE
It is mandatory that the operator has a full understanding
of all instructions, safety precautions and applicable
safety regulations before operating any high force
hydraulic equipment. If questions or concerns, contact
your local Enerpac Distributor or Authorized Service
Center.
5.2 Operating Instructions
To advance: Operate pump and valve so that pressurized
oil flow is directed in a controlled rate from the pump
reservoir to the cylinder coupler.
To retract: Operate pump and valve so that hydraulic oil
is directed at a controlled rate from the cylinder coupler
back to the pump reservoir.
Note that additional hydraulic components may be
required to control the rate at which the plunger retracts
under load.
NOTICE
CULP Series cylinders contain no plunger return spring.
External force will be required to fully retract the plunger
if it is not under load. A hydraulic pump equipped with a
vacuum valve will help aid plunger retraction.
6. Maintenance
& Storage
• Periodically check the hydraulic system for loose
connections leaks and obvious problems. Replace
any damaged components immediately.
• Monitor the oil temperature during operation. Do
not exceed oil temperatures above 150°F [65°C].
• Install dust cap(s) and plug(s) after the hydraulic
hoses are disconnected from the cylinder.
• Keep all hydraulic components clean.
• Change the hydraulic oil at the recommended
interval shown in the pump instruction sheet.
Change the oil immediately if contamination is
suspected.
• Store cylinders in the upright position, in a clean,
dry and secure location. Keep stored cylinders and
hoses away from heat and direct sunlight.
If repairs are required, refer to the Enerpac website for
the repair parts sheet applicable to your cylinder model
NOTICE
Hydraulic equipment must only be serviced by a
qualified hydraulic technician. For repair service, contact
the Enerpac Authorized Service Center in your area.
