Instruction Manual
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 qualied 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.

! WARNING
   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 qualied, 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 a 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 qualied 
personnel.
NOTICE: Using cylinder attachments or extensions reduces 
cylinder capacity by at least 50% per attachment/extension.
WARNING:  Before  operating  pump,  tighten  all  hose 
connections. 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 
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.
