Failure to comply with the following warnings may
result in personal injury as well as property
damage.
• Study, understand, and follow all instructions
provided with and on this device before use.
• Theusermustbeaqualiedoperatorfamiliarwith
the correct operation, maintenance, and use of cylinders.
Wear protective gear when operating
 hydraulicequipment.
 This device is NOT suitable for use as support
device! As the load is lifted, use blocking and cribbing
to guard against a falling load. Stay clear of a lifted
load before it is properly supported. Never rely on
hydraulic pressure to support a load.
Crush Hazard. Keep hands and feet away
from cylinder and workpiece during
operation.
• Do not exceed rated capacity of the cylinder or
  any equipment in the system. The cylinder is
designed for a max. pressure of 10,000 psi.
•Do not connect a cylinder to a pump with higher pressure rating.
•Do not subject cylinder to a shock loads, a load dropped
suddenly, causing the system pressure to exceed rated
pressure.
 Thesystemoperatingpressuremustnotexceedthe
pressure rating of the lowest rated component
the system. Install a pressure gauge or other load
measuring instrument to monitor the operating pressure. Burst
hazard exists if hose, connection or any other component in the
system exceed its rated pressure.
Avoid damaging hydraulic hose. Do not allow hose
to kink, twist, curl, crush, cut or bend so tightly that
 uid ow within the hose is blocked or reduced.
Periodically inspect the hose for wear.
Do not pull, position or move cylinder setup by the
hose. Use carrying handle or other means of safe
transport.
Do not handle pressurized hoses. Never attempt to
grasp a leaking pressurized hose. Ensure to release
the system pressure before disconnecting hydraulic
hose or connections.
 Hydraulic uid can ignite and burn. Keep
hydraulic
 equipment away from ames and heat. Excessive
 heat will soften seals, resulting in uid leaks. Heat
also weakens hose materials.
Cylinder must be on a stable base which is able
to support the load while pushing or lifting. Use shims,
friction material or constrains to prevent slippage
of the base or load. Ensure cylinder is fully engaged
into/onto adapters, extension accessories.
Center load on cylinder. Distribute load evenly across
the entire saddle surface. Do not off-center loads on
 a cylinder. The load can tip or the cylinder can
“kick out”.
Never try to disassemble a hydraulic cylinder, refer
 repairstoqualied,authorizedpersonal.ContactBVA
Hydraulics tech service for authorized service center.
 Do not subject hose to sharp objects or heavy
impact.
Hose material or seals must not come in contact with
corrosive materials such as battery acid, creosote-
 impregnated objects and wet paint. Never paint a
coupler or hose.
• No alteration shall be made to the cylinder.
• Use only factory authorized fasteners, accessories
  andhydraulicuid.
Heavy
INSTALLATION
NOTICE: Use an approved, high-grade pipe sealant to seal all
hydraulic connections.
1.
Remove the dust cover and rubber plug from coupler .
2. Inspectallthreadsandttingsforsignsofwearordamage,and
replaceasneeded.Cleanallthreadsandttings.
3. Connect hydraulic hose from hydraulic pump to the cylinder
coupler.Ensurethattherearenouidleaks.
4. Install in-line pressure gauge.
5. Check for leaks in system and have repaired by qualified
personnel.
NOTICE: The use of cylinder attachments or extensions reduces
the cylinder capacity by at least 50% per attachment/extension.
WARNING: Before operating the pump, tighten all hose
connections with proper tools. Do not overtighten. Connections
should only be tightened securely and leak-free. Overtightening can
cause premature thread failure or high pressure ttings to burst.
WARNING: Before repairs are made, depressurize cylinder.
Tipsforhydraulichoses&uidtransmissionlines:
•Avoidshortrunsofstraightlinetubing.Straightlinerunsdonot
provide for expansion and contraction due to pressure and/or
temperature changes.
•Reduce stress in tube lines. Long tubing runs should be
supported by brackets or clips.

OPERATION
Operate the hydraulic pump to advance and retract the cylinder.
Do not continue pumping when cylinder is fully extended. Internal
pressure will build up and may damage the seal of the cylinder.
WARNING: NEVER rely on hydraulic pressure alone to
secure a load! NEVER allow personnel to work or pass under
a load until the load is secured by cribbing, blocking, or other
mechanical means.
WARNING: To help prevent material fatigue if the cylinder
is to be used in a continuous application, the load should not
exceed 85% of the rated capacity.
WARNING:
Your cylinder, hose(s), couplings and pump all must
be rated for the same maximum operating pressure, correctly
connected and compatible with the hydraulic uid used. An
improperly matched system can cause the system to fail.
WARNING: All personnel must be clear before lowering load.
MAINTENANCE
1. Inspect hoses and connections daily. Replace damaged
components immediately with BVA Hydraulics Replacement
Parts only.
2. Tighten connections as needed. Use pipe thread sealing
compound when servicing connections.
3. Always use clean, approved hydraulic uid and change as
recommended or sooner if the uid becomes contaminated
(never exceed 400 hours). Follow pump manufacturers
instructionsforchangingandaddinghydraulicuid.Useonly
good quality hydraulic uid. We recommend BVA FJZ01 or
equivalent when using with hand pump, air pump, or electric
pump. Never use brake uid, transmission uid, turbine oil,
motor oil, alcohol, glycerin etc. Use of other than good quality
hydraulic oil will void warranty and damage the cylinder, pump,
hose etc.
4. Use an approved, high-grade pipe thread sealant to seal all
hydraulicconnections.Teontapecanbeusedifonlyonelayer
of tape is used and it is applied carefully (two threads back) to
prevent the tape from being introduced into hydraulic system. A
piece of tape could travel through the system and obstruct the
owofuidandadverselyaffectfunction.
Lubrication & Cleaning
Keep cylinder clean at all times.
1. Any exposed threads (male or female) must be cleaned and
lubricated regularly, and protected from damage. Lubricate with
light machine oil.
2. If a cylinder or ram has been exposed to rain, snow, sand,
airborne abrasive, or any corrosive environment, it must be
cleaned, lubricated, and protected immediately after exposure.
Daily clean exposed ram with clean cloth dampened with light
machine oil. Protect exposed ram from the elements at all times.
3. Keep the hydraulic system as free of dirt as possible. When
not in use, couplers must be sealed with dust covers. All hose
connections must be free of dirt and grime. Any equipment
attached to the cylinder must be kept clean.
Storage
Cylinders should be stored vertically with ram plunger fully retracted
in a dry, protected area, not exposed to corrosive vapor, dust or
otherharmful elements.When acylinder hasnot beenused for
a period of 4 months, it should be connected to a pump and fully
extended and then retracted a minimum of 5 times. This cycle will
lubricate the cylinder wall, reducing the possibility of corrosion and
damage thereof.
How to remove faulty coupler:
If cylinder does not retract,
1. Secure load by other means.
2. Depressurize pump and hose.
3. Remove the cylinder from application.
4. Disconnect and replace with new coupler.
