INSTALLATION
IMPORTANT! 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 fittings for signs of wear or damage,
and replace as needed. Clean all threads and fittings.
3. Connect hydraulic hose from hydraulic pump to the cylinder
coupler. Ensure that there are no fluid leaks.
4. Install in-line pressure gauge.
5. Check for leaks in system and have repaired by qualified
personnel.
Note: 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 leakfree. Overtightening can cause premature thread failure or
high pressure fittings to burst.
Before repairs are made, depressurize cylinder.
!
Tips for hydraulic hoses & fluid 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.

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

Center load on cylinder. Distribute load evenly
across the entire saddle surface. Do not

BEFORE USE
1. Before using this product, read the owner's manual
completely and familiarize yourself thoroughly with the
product, its components and recognize the hazards
associated with its use.
2. Verify that the product and the application are compatible.
If in doubt, call BVA Hydraulics Technical Service (888)
332-6419.
3. Inspect before each use. Do not use if bent, broken, leaking
or damaged components are noted.
4.
Replace worn or damaged parts and assemblies with BVA
Hydraulics authorized replacement parts only. Lubricate
as instructed in Maintenance Section.
5. Ensure method of confirming load is accurate and working
properly. Have gauge or load cell accuracy verified by
qualified personnel on a yearly basis.
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.
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.
Your cylinder, hose(s), couplings and pump all must
!
be rated for the same maximum operating pressure,
correctly connected and compatible with the hydraulic fluid
used. An improperly matched system can cause the system
to fail.
All personnel must be clear before lowering load.
!
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.
Important: Do not attempt to grasp with pliers or wrench
without first wrapping the jaws of such tool with rags or
similar padding.
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 fluid and change as
recommended or sooner if the fluid becomes contaminated
(never exceed 400 hours). Follow pump manufacturers
instructions for changing and adding hydraulic fluid. Use
only good quality hydraulic fluid. We recommend Mobil
DTE13M or equivalent when using with hand pump or air
pump; BVA Hydraulics Oil (F01) or equivalent when using
with electric pump. Never use brake fluid, transmission
fluid, 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. Teflon 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 flow of fluid and adversely affect function.
How to bleed air from system:
1. Place pump at a higher elevation than the hose and
cylinder as shown in figure 2 below.
2. Operate pump to fully extend and retract the cylinder 2 or
3 times. The objective is to force the air bubbles up hill
and back to the pump reservoir.
3. Follow pump instruction manual to bleed the air from
pump reservoir. On most pumps, air can escape by
opening the oil filler plug/screw.
