Figure 1 - Typical Lock-Nut Cylinder Components
INSTALLATION
NOTICE: 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. 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 qualied
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: 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.

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
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 conrming load is accurate and working
properly. Have gauge or load cell accuracy veried by
qualied 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.
WARNING: 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. Immediately after
lifting, thread the lock-nut into locking position.
