WaRnIng: uSE ExtREmE CautIon
when using high oil flow pumps with
CLP cylinders. oil flow from pump into
cylinder may be higher than the oil flow
capacity of the plunger travel restriction port. oil flow
at the plunger travel restriction port indicates that
maximum plunger travel has been reached. do not
exceed maximum plunger extension with CLP
cylinders.
WaRnIng: CLP cylinders do not have
a stopring. use these cylinders only in
vertical position with the plunger pointing
upwards.
WaRnIng: do not ExCEEd EquIP-
mEnt RatIngS. never attemp to lift a
load weighing more than the capacity of
the cylinder. overloading causes equip-
ment failure and possible personal injury. These
cylinders are designed for a maximum pressure of
700 bar [10,000 psi]. do not connect these cylinders
to a pump with a higher pressure rating.
ImPoRtant: use hydraulic gauges in
each hydraulic system to indicate safe
operating loads.
WaRnIng: off-center loads produce
unnecessary strain on cylinders and
create potential safety hazards. avoid
point loading. distribute the load evenly
across the entire plunger surface.
WaRnIng: Stay clear of loads supported
by hydraulics. after the load has been
raised or lowered, it must be blocked.
CautIon: Provide a solid support for
the entire base area. all Clp-Series
cylinders require a solid, flat lifting
surface capable of supporting the load
to be lifted. use of Clp cylinders on surfaces such
as sand, mud or dirt may result in cylinder damage.
WaRnIng: nEvER release hydraulic
pressure before the load is
mechanically blocked with lock nut
well positioned against cylinder base.
WaRnIng: nEvER PRESSuRIzE
unCouPLEd CouPLERS. only use
hydraulic equipment in a coupled system.
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.
CautIon: avoid sharp bends and
kinks that will cause severe back-up
pressure in hoses. Bends and kinks lead
to premature hose failure damage.
WaRnIng: Make sure that all system
components are protected from external
sources of damage, such as excessive
heat, flame, moving machine parts, sharp
edges and corrosive chemicals.
4.0 SIdELoad
ImPoRtant: Eliminate the presence
of sideload forces when using CLP
cylinders.
Sideload can occur through:
1. an eccentric load on the plunger.
2. a horizontal load on a structure.
3. a structure and/or cylinder misalignment.
4. non synchronized lifting actions.
5. non stable cylinder base support.
always use a flat, hard surface as a cylinder support
plate. use a low friction material on top of the saddle.
always use grease underneath swivel saddles (see
illustration 3 on page 4). The maximum allowable
sideload is 3% of the cylinder’s rated capacity.
5.0 oPERatIon
ImPoRtant: It is mandatory that the
operator has a full understanding of all
instructions, safety regulations, cautions
and warnings, before starting to operate
any of this high force tool equipment. In case of
doubt, contact Enerpac.
