PRODUCT DESCRIPTION

BVA Hydraulics Single Acting Low Prole Cylinder is designed for rated capacity pushing, spreading and pressing

jobs. A wide variety of applications exist for this category of product. Special skill, knowledge and training may be

required for a specic task and the product may not be suitable for all the jobs described above. Unsuitable applications

would include applications that call for a device to move, level or support persons, animals, hazardous materials,
mobile homes/dwellings in general, mirrors and/or plate glass, and/or to connect/secure hatches, components, etc.
between bulkheads. The user ultimately must make the decision regarding suitability of the product for any given
task and therefore accept responsibility for that decision. Immediately after lifting, loads must be supported by
appropriate mechanical means.

NEVER use hydraulic cylinder as a support device.

!

Always check connections before using. Alteration of these products is strictly prohibited. Use only those

!

adapters and attachments provided and approved by the manufacturer.

WARNING: To reduce the risk of personal injury and/or property damage, ensure that the rated working

!

pressure of each pressurized attachment be equal to or greater than the rated working pressure developed
by the hydraulic pump.

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 ttings for signs of wear or damage, and replace as needed.

3. Clean all threads and ttings.

4. Connect hydraulic hose from hydraulic pump to the cylinder coupler. Ensure that there are no uid leaks.

5. Install in-line pressure gauge.

6. Check for leaks in system and have repaired by qualied personnel.

Note: The use of cylinder attachments or extensions reduces the cylinder capacity by at least 50% per attachment/
extension.

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.

!

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.

.
