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. Use adequate eye protection when operating or near
this equipment.
6. Ensure method of confirming load is accurate and working
properly. Have gauge or load cell accuracy verified by
qualified personnel on a yearly basis.
7. Cylinders should be stored where protected from the
elements, abrasive dust, and damage. These cylinders
should be stored in the vertical position.
INSTALLATION
IMPORTANT! A double-acting cylinder must be powered by
a pump with 4-way valve. Both couplers on the cylinder must
be connected. Use an approved, high-grade pipe sealant to
seal all hydraulic connections.
1. Remove the dust covers and rubber plugs from
couplers.
2. Inspect all threads and fittings for signs of wear or damage,
and replace as needed.
3. Clean all threads and fittings.
4. Connect two hydraulic hoses from the 4-way pump to the
cylinder couplers. Ensure that there are no fluid leaks.
5. Install in-line pressure gauge.
6. 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.
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 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.
