INSTALLATION
NOTICE: Use an approved, high-grade pipe sealant to seal
all hydraulic connections.
1.
Remove the oil port plug from cylinder
.
2. Inspect all threads and ttings for signs of wear or damage,
and replace as needed. Clean all threads and ttings.
3. Connect coupler and hydraulic hose from hydraulic pump to
the cylinder. Ensure that there are no uid leaks.
4. Install in-line pressure gauge.
5. Check for leaks in system and have repaired by qualied
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: Depressurize cylinder before making any
repairs.
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 cylinder
seals.
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 fresh hydraulic uid and change as recommended,
or sooner, if the uid becomes contaminated (never exceed
400 hours). Follow pump manufacturer’s instructions for

changing and adding hydraulic uid. Use only premium
quality hydraulic uid. BVA Hydraulics Oil (F01) or equivalent
is recommended when using with electric pump. Do not use
brake uid, transmission uid, turbine oil, motor oil, alcohol,
glycerin etc. Use of other than premium quality hydraulic
oil will void the warranty and damage the cylinder, pump,
hose etc.
4.
Use high-grade, pipe thread to seal all hydraulic connections.
Teon 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. Pieces of tape
may 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 free of dirt. When not in use,
couplers should 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. If a cylinder has not
been used for a period of 4 months, it should be connected to
a pump and fully extended and retracted through a minimum
of 5 cycles. Cycling the cylinder will lubricate the cylinder wall,
reducing the possibility of corrosion and damage.
Faulty Ram Coupler:
If cylinder does not retract,
1. Secure load by other means.
2. Depressurize pump and hose.
WARNING: If ram does not retract after depressurizing
system, discontinue use and contact BVA Customer
Service. Attempting to remove a faulty ram coupler
may result in personal injury and/or property damage.
